Background technology
Car front suspension frame spring adopts the cold-drawn spring steel wire of diameter of phi 11~Φ 16mm mostly, in the cold coiling mode, manufactures.Main equipment for this bearing spring of cold coiling is numerical-control spring coiling machine.
The existing drawing-inroller 6 of part numerical-control spring coiling machine adopts flat key 8 to connect with feed spool 1, and adopts screw 7 tightenings, and its structure as shown in Figure 6.During production, need back down the pitch of spring, and the resistance of deformation of thick line wire-diameter steel is very large, make drawing-inroller be subject to very large axial force, and steel wire is very large rocking of several circles in end, be close to and determine screw and be difficult to fixedly axial location, cause drawing-inroller to produce axial float, affect pushing precision and spring forming accuracy, product percent of pass is affected, and the drawing-inroller size is large, weight is large, therefore rotary inertia is large, low-response, productive temp are restricted.In addition, large-sized drawing-inroller materials are also many, and manufacturing cost is also high.
Summary of the invention
Purpose of the present invention is exactly that a kind of axial float problem while improving existing drawing-inroller work is provided in order to overcome the defect that above-mentioned prior art exists, and makes the lathe feeding more stablize accurate spring coiling machine feeding positioning component.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of spring coiling machine feeding positioning component, be set on the feed spool of spring coiling machine, it is characterized in that, this feeding positioning component consists of drawing-inroller and positioner, and two arc grooves are offered in the described drawing-inroller outside, and arc groove and drawing-inroller both sides end face are equidistant, described positioner comprises positioning shaft sleeve, swelling tapered sleeve and trim ring, described swelling tapered sleeve is set in outside feed spool, and described positioning shaft sleeve is set in outside the swelling tapered sleeve, and described trim ring is located at the front end face of swelling tapered sleeve.
Described positioning shaft sleeve is with flange, and inner surface is with tapering, and the outer surface part is with tapering, with the quenched and tempered steel manufacture of Quenching Treatment.
Described swelling tapered sleeve has thin groove outward, and outer surface is with tapering, with quenchless spring steel manufacture.
Described positioning shaft sleeve and swelling tapered sleeve are pressed abd fixed on feed spool through trim ring.
Described drawing-inroller is offered two arc grooves equidistant with end face, offers 6 on end face for the screw via hole of clamping is installed.
Described drawing-inroller is arranged on positioning shaft sleeve through screws clamp.
Compared with prior art, the present invention is fixed on drawing-inroller on the feed spool of spring coiling machine with positioner, utilizes positioning shaft sleeve flange location, clamps drawing-inroller, and the axial float problem while having solved former drawing-inroller work, make feeding more stable accurately; The gross weight of drawing-inroller and positioner is only 2/3 of original structure, and inertia reduces, and has alleviated the burden that lathe drives, and is convenient to busy shift, commutation; The Novel feeding wheel construction is simplified, and has greatly reduced the use of high-alloy steel, has saved fee of material and processing charges.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The structural representation that Fig. 2 is drawing-inroller;
The structural representation that Fig. 3 is positioning shaft sleeve;
The structural representation that Fig. 4 is the swelling tapered sleeve;

In figure, 1 is that feed spool, 2 is that drawing-inroller, 3 is that positioning shaft sleeve, 4 is that swelling tapered sleeve, 5 is that trim ring, 6 is that screw, 8 is flat key for having drawing-inroller, 7 now.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
A kind of spring coiling machine feeding positioning component, be set on the feed spool 1 of spring coiling machine, its structure as shown in Figure 1, comprise drawing-inroller 2, positioning shaft sleeve 3, swelling tapered sleeve 4 and trim ring 5, as shown in Figure 2, two arc grooves are offered in the outside to the structure of drawing-inroller 2, and the end face of groove and drawing-inroller 2 is equidistant, the thickness that makes drawing-inroller 2 is attenuate greatly, also offers 6 on the end face of drawing-inroller 2 for the screw via hole of clamping is installed.Positioning shaft sleeve 3, swelling tapered sleeve 4 and trim ring 5 have formed positioner, the structure of positioning shaft sleeve 3, swelling tapered sleeve 4 and trim ring 5 is respectively as shown in Fig. 3, Fig. 4, Fig. 5, positioning shaft sleeve 3 is with flange, inner surface is with tapering, the outer surface part is with tapering, manufacture positioner for the axial of drawing-inroller 2 and positioning and clamping radially with the quenched and tempered steel of Quenching Treatment, have thin groove outside swelling tapered sleeve 4, outer surface is with tapering, with quenchless spring steel manufacture, positioning shaft sleeve 3 is pressed abd fixed on feed spool 1 through trim ring with swelling tapered sleeve 4.
Positioner utilizes positioning shaft sleeve 3 flange location, clamps drawing-inroller 2, and the axial float problem while having solved drawing-inroller 2 work makes feeding more stable accurately; The gross weight of drawing-inroller 2 and positioner is only 2/3 of original structure, and inertia reduces, and has alleviated the burden that lathe drives, and is convenient to busy shift, commutation; The Novel feeding wheel construction is simplified, and has greatly reduced the use of high-alloy steel, has saved fee of material and processing charges, and specific practice is:
(1) assemble the feeding positioning component by Fig. 1: swelling tapered sleeve 4 is installed on feed spool 1, positioning shaft sleeve 3 is installed on swelling tapered sleeve 4, after the axial location of the flange of adjustment positioning shaft sleeve 3, use screw in compression by trim ring 5, positioning shaft sleeve 3 fits tightly with the conical surface of swelling tapered sleeve 4, is fixed on feed spool 1;
