Below by by Fig. 2 to Fig. 5 to the installation of this measurement component bar 14 with to be fasteningly described.From position shown in Figure 1, user by this measurement component bar 14 on importing direction E, namely import to from down in the axial direction in the end segments 24 of tubulose of this transmission shaft 11.Due to the tapering of the tapered segment 14a of this measurement component bar 14, the end segments 24 of this transmission shaft 11 this with very little size radially, flexibly expansion and being radially pressed to from outside the section 14a of the taper of this measurement component bar 14.Go out as shown in FIG. 2, the 1st stage that upper end side is importing motion of this measurement component bar 14 reclines mutually with this downside ejecting bolt 20.At this, this piston section 27 ejecting bolt 20 will remain in the position of its outside orientation by these spherical clamping bodies 13, and these clamping bodies are arranged in the annular groove 25 of this closing sleeve 12 in this position.
Further, the axial importing of this measurement component bar 14 on importing direction E causes: this ejects bolt 20 and resists the power of the 2nd spring 19 and axially move up, and wherein these spherical clamping bodies 13 are remained in the position of its outside orientation by this measurement component bar 14 now.The end segments 24 of this transmission shaft 11, due to the section 14a of the taper of this measurement component bar 14, still further radial, flexibly expand.This situation is shown in Figure 3.
This measurement component bar 14 imports in the end segments 24 of the tubulose of this transmission shaft 11, until these lower ends of this transmission shaft 11 recline mutually with the bracket 15 of this measurement component bar 14.This in the diagram shown in situation under, the end segments 24 of this tubulose following radial, flexibly expand, make this end segments completely under inherent strain (Eigenspannung) to tensioning on the cover of this measurement component bar 14.In this situation, the depression 16 of this annular of this measurement component bar 14 is positioned at the scope of these spherical clamping bodies 13, make these clamping bodies can implement one radially-inwardly orientation motion and be attached in this depression 16.By this motion of these spherical clamping bodies 13, this closing sleeve 12 is released and implements the motion (see Fig. 4) of an axially upwards orientation due to the power of the 1st spring 17.The clamping surface 21 of this inclination reclines from outside with these spherical clamping bodies 13 and is squeezed into the depression 16 of this measurement component bar 14 by these clamping bodies further thus.Due to the inclination of clamping surface 21, from this closing sleeve 12 to these spherical clamping bodies 13 and power from these clamping bodies to this measurement component bar 14 that apply from have one this longitudinal axis L ' the component of axis that acts on of direction, this measurement component bar 14 is drawn in the end segments 24 of the tubulose of this transmission shaft 11 thus.Guarantee thus, the lower end of this transmission shaft 11 abuts in bracket 15 place of this measurement component bar 14 by whole circumference.This situation is shown in Figure 5.
The lower end of this transmission shaft 11 is guaranteed the reclining of bracket 15 place of this measurement component bar 14: this measurement component bar 14 is accurately relative to this transmission shaft 11 axially orientation, that is, the longitudinal axis L of this measurement component bar 14 and this transmission shaft 11 longitudinal axis L ' extend parallel to each other.The section 14a of the taper of this measurement component bar 14 guarantees to when the expansion that the access in the end segments 24 of this transmission shaft 11 is flexible when it, radial: these two longitudinal axis L overlap with L', that is, this measurement component bar 14 is located exactly relative to this transmission shaft 11.
Due to the clamping force component of the axis that clamping surface 21 and this of this inclination obtain thus, this measurement component bar 14 automatically aligns and moves in its nominal position and also keeps there under prestress.The clamping force of this radial direction between the radial direction of the tapered segment 14a on the top of this measurement component bar 14 and this transmission shaft 14, the end segments 24 of resilient expansion supports the location accurately of this measurement component bar 1 and tool has the following advantages, and makes it possible to transmit high torque between this transmission shaft 11 and measurement component bar 14.
Fig. 6 to 9 shows these the independent stages removed from this unitor 10 by this measurement component bar 14.Fig. 6 show this measurement component bar 14 install after of the state diagram corresponding with Fig. 5, wherein these spherical clamping bodies 13 are compressed in the depression 16 of this measurement component bar 14 by the clamping surface 21 of this closing sleeve 12 and the lower end of this transmission shaft 11 abuts in bracket 15 place of this measurement component bar 14.As indicated by arrow B in figure 6, this closing sleeve 12 moves down by the power that user resists the 1st spring 17 from this installation site.Carry out this to move until the lower end of this closing sleeve 12 reclines (see Fig. 7) mutually with the bracket 15 of this measurement component bar 14 equally.In this position, the annular groove 25 of this closing sleeve 12 is positioned at the scope of these spherical clamping bodies 13, makes these clamping bodies can implement a radial motion.In the motion of a further orientation downwards of this this closing sleeve 12, this closing sleeve 12 is applied the power of a downward orientation on this measurement component bar 14 by bracket 15 by user.This is ejected bolt 20 supported by this, and this ejects bolt applies a downward orientation because the 2nd spring 19 is same power to this measurement component bar 14.By the motion of the downward orientation of this measurement component bar 14, these spherical clamping elements 13 are laterally shifted and are extruded in this annular groove 25, make this measurement component bar 14 then eject bolt 20 release from this transmission shaft along this transmission shaft 11 by this.But the clamping force provided by the flexible expansion of the end segments 24 due to transmission shaft 11 that drops of this measurement component bar 14 is avoided, and makes user this measurement component bar 14 can be taken off downwards.
As in figure 6 by arrow P and P' instruction, replace in by user by one electric, that power source that is pneumatic or hydraulic pressure realizes the downward orientation of closing sleeve 12 offset movement, removing of measurement component bar 14 can robotization.Can produce or apply the power acted between this transmission shaft and this closing sleeve by this power source, make this closing sleeve move down thus.According to arrow P in figure 6 when the power that importing such as is pneumatic impacts (Kraftsto β), this power acts between the convex shoulder 18 and this closing sleeve 12 of this transmission shaft 11, makes this closing sleeve move down in the direction of arrow B thus.
For this reason, can additionally propose, an applying power on bolt 18 is ejected to this, its mode is, the power of a such as hydraulic pressure impact according to arrow P ' act on the upside that this ejects bolt 20, this ejects bolt 20 and is pushed downwards thus and on this measurement component bar 14, applies an ejecting force (Auswerfekraft) thus.
