如果将部件10、20固定在架台25上,将接合线(间隙40的位置)从上侧用切削刀具60在规定的槽41处切削。 If the member 10, 20 is fixed on the stand 25, the engagement groove 41 of cutting line (gap 40 positions) from the upper side with a cutting tool 60 in a predetermined. 槽41为长方形。 Groove 41 is rectangular. 槽41相对的边(部件10、20的端部)是平行的。 Groove 41 opposite sides (end elements 10 and 20) are parallel.

该切削宽度,至少设定大到不留有形成间隙40的两侧壁面的程度。 The cutting width, is set at least as large as the extent of not leaving a gap is formed on both sides of the wall 40. 切削的深度为直到突出片23的上面为止。 Depth of cut for the top 23 until the projecting piece. 切削通过干切削进行。 Cutting through dry cutting.

在上述中,对切削刀具60是用圆锯表示的,但槽铣刀或者立铣刀也有同样效果。 In the above, the cutting tool 60 is represented by a circular saw, but slot cutters or end mills have the same effect. 主要要求切削的宽和深度要恒定。 The main requirements of the cutting width and depth to be constant.

接着,把由切削刀具60切出来的切屑,由从切屑除去咀50吹出的压缩空气吹开或者由吸尘器吸入除去。 Next, cut out by the cutting tool 60 chips from the chip is removed by blowing compressed air nozzle 50 by a vacuum cleaner sucked on or removed.

在切屑除去咀50的后方,配置有与突部12、22的上面、其外侧部件10、20的上面以及槽41内的突出片23接触的橡胶板95。 In the rear of the nozzle 50 of the chip removal, the rubber plate 95 is disposed above the projecting portion 12 and 22, upper and outer side member protruding pieces 10, 20 within the groove 41 of the contact 23. 这样遮住而使切屑不向后方移动。 Such chips are not leaving the cover moves backward.

在制作槽41后,在槽41内插入填补材料30。 After the production of grooves 41, fill material 30 is inserted in the groove 41. 这就是将卷盘90的填补材料30拉出,导引到槽41内并由按压辊70向下方按压插入填补材料30。 This is to fill material 30 of the reel 90 is drawn out, guided into the groove 41 by the pressing roller 70 is pressed downward to fill material 30 is inserted. 按压辊70通过气缸装置71(或者压缩弹簧),使填补材料30的上面向着槽41的下底面压入。 The pressing roller 70 by the cylinder device 71 (or compression spring), so that filling material above the bottom surface 30 of the groove 41 towards the lower press-fitting.

在使填补材料30的下面接触到突出片23的上面时,以填补材料30的上面占据比突部12、22的上面还稍微高的位置来确定填补材料30的高度尺寸。 In making the filling material 30 into contact with the projecting piece below the top 23 to the top 30 of the fill material occupying also slightly higher than the upper projecting portion 12 and 22 positions to determine the height of fill material 30.

填补材料30的截面形状几乎与槽41的截面形状相同。 30 is a cross-sectional shape of the filling material is almost cross-sectional shape of the groove 41 of the same. 填补材料30的宽度几乎与槽41的宽度相同。 The width of the filling material 30 is almost the same as the width of the groove 41. 然而,填补材料30通过按压辊70比较容易地进入槽41,但在部件10(20)和填补材料30之间不要空出过大的间隙。 However, filling material 30 by the pressing roller 70 relatively easily into the groove 41, but between the member 10 (20) and a filling material 30 is not too large empty space. 填补材料30的宽度和槽41的宽度之间的差为不到1mm的大小。 The difference between the width and the width of the groove 41 between the filling material 30 is less than 1mm in size.

填补材料30被卷在自由旋转的卷盘90上,并按顺序经过矫正辊91a、91b、91c、送出辊92a、92b、92c、92d、92e、92f直到按压辊70。 Fill material 30 is wound on a reel 90 to rotate freely, and sequentially after correction rollers 91a, 91b, 91c, delivery roller 92a, 92b, 92c, 92d, 92e, 92f until the pressure roller 70. 这些辊都接触填补材料30。 These rolls are exposed to fill material 30.

矫正辊91a、91b、91c夹住被卷在卷盘90上的填补材料30,是去掉填补材料30的卷摺、使其呈直线状的部件。 Correction rollers 91a, 91b, 91c sandwiched is wound on a reel 90 of fill material 30, is to remove the fill material 30 of the roll-folded, so that the member linearly. 矫正辊91a、91b主要接触被卷在卷盘90上的填补材料30的内侧面。 Inner side surface 91a, 91b is exposed primarily to the correction rollers 90 roll on the reel 30 of the filling material. 矫正辊91c主要触接被卷在卷盘90上的填补材料30的外侧面。 The main outer side correction rollers in contact 91c is wound on a reel 90 of fill material 30. 矫正辊91a、91b、91c向着填补材料30的接触部(辊的外周部)为凹状。 Correction rollers 91a, 91b, 91c toward the fill material contact (roller outer peripheral portion) 30 of a concave shape. 在这个凹部放入填补材料30。 In this recess 30 into the fill material.

送出辊92a、92b、92c、92d是使填补材料30从卷盘90卷回、并供给槽41的辊。 Delivery roller 92a, 92b, 92c, 92d is to fill material 30 from the reel 90 is rewound, and the supply tank 41 rolls. 该送出辊接触填补材料30的高度方向的面(沿槽41的高度方向的面)。 The delivery roller contacts the material fill height direction of the surface 30 (the surface along the height direction of the groove 41). 该送出辊与填补材料30的接触部为凹状。 The sending roll and the contact portion of the filling material 30 in a concave shape. 在该凹部装入填补材料30。 Loaded in the recess 30 to fill the material. 送出辊92a、92c通过扭矩限制器由电动机驱动。 Delivery roller 92a, 92c is driven by a motor via a torque limiter. 由此,用规定的力使填补材料30沿长方向送出。 Thus, with the power to make regulations sent fill material 30 along the longitudinal direction. 送出辊92a、92c分别连接送出辊92b、92d。 Delivery roller 92a, 92c are connected to the delivery roller 92b, 92d. 例如在送出辊92a、92c、92b、92d的外周部有齿轮,送出辊92a、92c的齿轮啮合在送出辊92b、92d的齿轮上。 For example, in off rollers 92a, 92c, 92b, 92d of the outer peripheral portion of a gear, the delivery roller 92a, 92c of the gear mesh at the send-out roller 92b, 92d of the gear.

送出辊92a、92b、92c、92d、92e、92f是填补材料30的导向辊。 Delivery roller 92a, 92b, 92c, 92d, 92e, 92f is to fill material 30 of the guide roller. 在送出辊92e、92f上没有电动机。 In sending roller 92e, no motors on 92f. 送出辊92e、92f接触填补材料30的高度方向的面(沿槽41的高度方向的面)。 Surface (a surface along the height direction of the groove 41) off rollers 92e, 92f contact the height direction of the filling material 30. 该送出辊与填补材料30的接触部为凹状。 The sending roll and the contact portion of the filling material 30 in a concave shape. 在该凹部装入填补材料30。 Loaded in the recess 30 to fill the material.

在使填补材料30插到槽41时,在按压辊70的后方,通过旋转刀具80使填补材料30临时插入接合到部件10、20上。 In the filling material 30 so that when inserted into the groove 41, in the rear of the pressing roller 70, by rotating the tool 80 so that the temporary filling material 30 inserted to the engaging member 10, 20. 该接合就是由旋转刀具80进行的摩擦搅拌接合。 The engagement of the rotary cutter 80 is carried out by friction stir welding.

通常,摩擦搅拌接合的旋转刀具在大直径部的前端有小直径部,但该旋转刀具80没有小直径部。 Typically, a rotating friction stir welding tool in the front end of the large diameter portion has a small diameter portion, but not the rotary tool 80 the small diameter portion. 旋转刀具80的前端是平的。 The front end of the rotary tool 80 is flat. 旋转刀具80从上方插入到部件10、20和填补材料30中。 The rotary cutter 80 is inserted from above into the members 10, 20 and 30 in the fill material. 旋转刀具80的轴心与通常的旋转刀具同样是倾斜着的。 Rotary tool axis and a normal rotary tool 80 is inclined in the same. 倾斜方向是相同的。 Inclination direction is the same. 旋转刀具80处于旋转状态。 The rotary cutter 80 is rotating.

旋转刀具80的直径为比槽41的宽度稍微大一些。 The diameter of the rotating cutter 80 is slightly larger than the width of the groove 41 of some. 例如,槽41的宽度为3mm时,旋转刀具80的直径为6mm。 For example, the width of the groove 41 is 3mm, the diameter of the rotary cutter 80 is 6mm. 向突部12、22的旋转刀具80的插入深度,由于为临时插入,因而只是少量插入。 The projecting portions 12 and 22 of the rotary tool 80 of the insertion depth, due to the temporary insertion, and thus only a small amount of insertion. 例如从突部12、22的上面起为1.0mm。 From the above example, the protrusions 12 and 22 is 1.0mm. 该临时的接合在由后述的旋转刀具81的摩擦搅拌接合的时候,填补材料30有从槽41不脱离的接合强度。 The temporary engagement in the rotary cutter 81 described later, when the friction stir welding, filling material 30 has grooves 41 without departing from the joining strength. 即,设为能够得到该接合强度的插入深度。 That is, a bonding strength can be obtained in the depth of insertion.

填补材料30的上端位于比突部12、22的顶还高的位置。 The upper end of fill material 30 is positioned higher than the top of the projecting portion 12 and 22 positions. 填补材料30也比突部12、22突出。 Fill material 30 also protruding portions 12 and 22 protrudes. 由此,即使由于填补材料30和槽41的制作误差在两者之间有间隙,通过填补材料30的突部也能够埋上该间隙。 Accordingly, even if the filling material 30 and the groove 41 of the fabrication error in a gap between the two, by the projecting portion 30 of the filling material can also be buried on the gap. 从而,能够使填补材料30在部件10、20上坚固地固定。 Thus, possible to fill material 30 firmly fixed to the members 10, 20. 另外,在填补材料30由按压辊70按压插入时,使填补材料30能够紧结合在接突出片23上,并能够形成坚固的接合。 Further, when the filling material 30 is pressed by the pressing roller 70 is inserted, so that filling material 30 can be tightly bonded to protruding contact piece 23, and robust bond can be formed.

在通过旋转刀具80接合时,接合部的上面侧呈稍凹陷。 When the rotary cutter 80 by joining the top side of the joint was slightly dented. 在图7、图8中平面地图示了接合部的上面。 In FIG. 7, FIG. 8 illustrates a top planar joint.

在旋转刀具80的大直径部的外周面上由于不设置螺钉,所以在摩擦搅拌接合时不用担心把填补材料30、突部12、22向旋转刀具80的轴方向挤出。 In the outer peripheral surface of the large diameter portion of the rotary cutter 80 is not provided due to the screw, there is no fear of the filling material 30, projecting portions 12 and 22 to the extrusion axis 80 of the rotary tool when friction stir welding.

旋转刀具80的位置尽量靠近按压辊70是理想的。 Position of the rotary cutter 80 is as close to the pressing roller 70 is desirable.

接着,由旋转刀具81,摩擦搅拌接合突部12、22和填补材料30三者。 Next, the rotary tool 81, the friction stir welding protrusions 12, 22 and 30 of the three filling material. 该接合是为了使部件10、20真正地接合的接合。 The engagement member 10, 20 is to make the engagement really engaged.

旋转刀具81是在大直径部的前端有小直径部的旋转刀具。 The rotary cutter 81 is at the front end of the large diameter portion has a small diameter portion of the rotary tool. 小直径部的直径比填补材料30的宽度和槽41的宽度稍大。 The diameter of the small-diameter portion is slightly larger than the width of the width of the groove filling material 30 and 41. 在摩擦搅拌接合时,旋转刀具81的大直径部和小直径部的交界的下端,在比除去突部12、22的部件10、20的上面靠上方,位于比突部12、22的顶靠下方的位置。 When friction stir welding, the lower end of the rotary tool 81 of the large diameter portion and a small diameter portion of the junction, 10 and 20 positioned above the top, is located over the top portion 12, 22 by projecting member projecting portions 12 and 22 than the removal of lower position. 同样,旋转刀具81的小直径部的前端位于突出片23的上面的付近或者突出片23的内部的位置。 Similarly, the front end of the rotary tool 81 the small diameter portion is located above the projecting piece 23 projecting to pay near or inside the sheet 23 position.

如上所述在填补材料30和部件10、20之间有间隙时,用比除去突部12、22的部件10、20的上面靠上方的突部12、22和填补材料30埋上所述间隙。 As described above when a gap between the filling material 30 and the member 10, 20, by using the ratio of the upper projection 12, 22 and filling material 30 buried in the upper projecting portion 12 and 22 to remove parts of the gap 10, 20 . 接合部的上面侧稍微凹陷。 The upper side of the joint is slightly dented.

接着,在必要时对比除去突部12、22的部件10、20的上方靠上方的突部12、22和填补材料30(为接合部)进行切削加工,并使其呈平滑状。 Then, if necessary to remove the upper member contrast projection 12, 22 10 and 20 by the projecting portion above the filling material 12, 22 and 30 (for engagement) by cutting, and it was a smooth shape.

图9出示了在摩擦搅拌接合部中切除比部件10、20的表平面靠上的突部12、22和接合部、对摩擦搅拌接合部进行了平滑加工的截面。 Figure 9 show a friction stir weld or joint member 10, 20 in the removal ratio of the surface plane by the projecting portion 12, 22 and the engagement of the friction stir joining with the smoothing processing section. 43是摩擦搅拌接合部。 43 is a friction stir joining.

切削刀具60、旋转刀具80、81分别在接合线的直角方向、即间隙40(槽41)的宽方向能够单独地移动。 Cutting tool 60, the rotary cutter 80 and 81 respectively in a direction perpendicular to the bonding wire, i.e. the gap 40 (groove 41) in the width direction can be separately moved. 这是为了检测接合线(间隙40、槽41)的位置、使切削刀具60、旋转刀具80、81位于其中心的原故。 This is to detect the joining line (gap 40, groove 41) in position, the cutting tool 60, the rotary tool 80, 81 at the center thereof exigencies. 另外,切削刀具60,旋转刀具80、81能够分别单独地上下动作。 Further, the cutting tool 60, the rotary tool 80, 81 can move up and down independently, respectively. 这是为了规定由切削刀具60形成的切削深度(槽41的深度)、由旋转刀具80、81形成的接合深度的原故。 This is the cutting depth (the depth of the groove 41) by the cutting tool 60 to a predetermined formation, the depth of engagement by the exigencies of the rotary tool 80, 81 is formed.

为此,分别具备检测突部12、22的光学传感器(图中未示)。 To this end, the projecting portion 12 and 22 respectively, with the detection of the optical sensor (not shown). 光学传感器检测两个突部12、22的宽度位置,使切削刀具60、旋转刀具80、81位于该宽度的中心位置。 The optical sensor detects the position of the width of the two protrusions 12 and 22, the cutting tool 60, 80, 81 located in the center of rotation of the tool width. 另外,检测突部12、22的顶的位置,规定切削刀具60、旋转刀具80、81的插入深度。 In addition, the top of the protrusion 12, 22 detecting the position of a predetermined cutting tool 60, the insertion depth of the rotary tool 80, 81.

由于在由旋转刀具81进行摩擦搅拌接合时,产生按压填补材料30的反力,所以由送出辊92a、92b、92c、92d给与填补材料30的驱动力必须是与该按压反力方向相对的力。 Since the rotary tool 81 by the friction stirring joining, pressing the filling material to produce a reaction force 30, so by the delivery roller 92a, 92b, 92c, 92d to give the driving force of the filling material 30 must be opposite to the direction of the pressing reaction force force.

从送出辊92e、92f到按压辊70的距离、从按压辊70到旋转刀具80的距离、从旋转刀具80到旋转刀具81的距离,根据按压所述填补材料30的反力,必须是在各自的位置使填补材料30不发生压曲的距离。 From the delivery roller 92e, 92f to the pressing roller 70 of the distance, the distance 70 to the rotary tool 80 from the pressure roller, the rotary tool 80 to the rotary tool 81 of the distance, according to the pressing reaction force of the padding material 30, must be in the respective position so that fill material 30 from buckling does not occur.

根据该实施例,在对接两个部件的时候,即使沿着接合线存在一定间隙,也可以切削接合线形成规定的间隙,接着插入填补材料,实质地除去接合线的间隙,由于实施摩擦搅拌接合,而能够进行良好的接合。 According to this embodiment, the docking of the two members, even though there is a certain gap along a joining line, the bonding wires may be cut to form a gap defined, and then insert the filling material, the gap of the bonding wire is removed substantially, due to the implementation of the friction stir welding , and can be a good joint.

摩擦搅拌接合以后,使接合部呈平滑状,在实施极细的线加工的精加工时,由于填补材料30的材质与母材(部件10、20)为同一材质,所以接合部的变色少,外观也不会变坏。 After the friction stir welding, the joint portion was smooth shape, when implementing hairlines finishing machining, the material due to the filling material and the base material (10, 20 member) 30 of the same material, so the joint less discoloration, Appearance does not deteriorate.

另外,旋转刀具80与旋转刀具81同样,也可以在大直径部的前端有小直径部。 Further, the rotary tool 80 and the rotary tool 81, as well, at the front end of the large diameter portion has a small diameter portion.

下面,用图11说明本发明的其它的实施例。 Next, using Figure 11 illustrates another embodiment of the present invention. 在该图中的符号与图1~图10相同的符号实质上是相同的部件。 The same reference symbols as in Fig. 1 to 10 in this figure is essentially the same components. 该实施例主要是废除了临时接合的步骤。 This embodiment is mainly the abolition of temporary bonding step.

送出辊92a、92b、92c、92d与图2的情况比较,是设置方向改变了90度。 Delivery roller 92a, 92b, 92c, 92d and the comparative case of Fig. 2, is provided to change the direction of 90 degrees. 虽然也可以在从矫正辊91a~91b到送出辊93a~93d之间有导向辊,但在这里除去,取而代之的是设置导向管94。 Although it may be in the correction rollers 91a ~ 91b to the delivery roller has a guide roller 93a ~ 93d, but here was removed, replaced by a guide tube 94 is provided. 导向管94是具有耐磨耗性和刚性并且有挠性的部件。 The guide tube 94 having a wear resistance and rigidity and has a flexible member. 例如是聚四氟乙烯(注册商标)管。 For example, polytetrafluoroethylene (registered trademark) tube. 在导向管94的内径和填补材料30之间有适当的间隙。 Between the inner diameter of the guide tube 94 and the filling material 30 has a proper gap. 导向管94的两端固定在设置了该摩擦搅拌接合装置的行走体(图中未示)上。 The guide tube 94 is fixed at both ends of the set of friction stir welding apparatus traveling body (not shown). 在图11中对导向管94内的填补材料30用实线表示。 In Figure 11, the material 30 to fill the inside of the guide tube 94 indicated by a solid line. 虽然也可以有按压辊70,但这里除去了。 Although you can also have a pressing roller 70, but here removed. 并除去了临时接合用的旋转刀具80。 And removing the temporary bonding of the rotary tool 80.

送出辊92a~92d的送出力,是能够对由旋转刀具81产生的所述按压反力而提供给填补材料30的力。 The force of feeding out roller 92a ~ 92d, and is capable of rotating the cutter 81 by a reaction force generated by the pressing force provided to the fill material 30. 从送出辊93a~93d到旋转刀具81的距离,是不使填补材料30由所述按压反力而产生压曲的距离。 The distance from the delivery roller 93a ~ 93d to the rotary cutter 81, which does not cause the filling material 30 is pressed by a reaction force generated from buckling. 由此,能够省略旋转刀具80的临时接合。 Thereby, possible to omit the rotary tool 80 of the temporary engagement.

使用送出辊92a~92f时,使应该把它们设置为对于行走体可自由移动,但在取代它们使用导向管94时是能够使构成变得简单。 When using the delivery roller 92a ~ 92f, so they should be set for running body can move freely, but they are used to replace the guide tube 94 is capable of constituting simple.
