[0035] The utility model is further described in conjunction with the following embodiments.

[0036] Example 1.

[0037] like Figure 1-6 As shown, a main reducer tooling processing positioning device comprises a positioning base plate 1, on which are bolted no less than two supporting positioning seats 2 and a rotation limit positioning seat 3, on which are provided arc bayonet sockets 4, on which a main reducer blank 5 is simultaneously fitted and clamped, and on which the rotation limit positioning seat 3 is also movably mounted a rotation limit assembly, on which the side of the main reducer blank 5 is provided two corresponding bearing holes 6, on which the side of the bearing hole 6 is mounted a side pressure supporting mechanism, and the side pressure supporting mechanism and the bearing hole 6 are movably pressed and fitted.

[0038] The present application is used for processing and positioning of a blank 5 of a main reducer for automobiles. First, the bottom support and fixation of the entire processing and positioning device is performed through the positioning base plate 1. Then, the main reducer for automobiles is supported by the arc bayonet 4 on the supporting positioning base and the rotating limit positioning seat 3, so that the main reducer for automobiles can reach a horizontal level and the center of a circle is fixed. Then, the rotating limit assembly slides on the rotating limit positioning seat 3 and cooperates with the main reducer for automobiles to limit the horizontal rotation of the main reducer blank 5. The indexing holes of the disk 7 on the blank and the threaded holes of the bearing cover are accurately processed to prevent the main reducer blank 5 from rotating. Then, the main reducer is pressed and fixed by the side pressure supporting mechanism.

[0039] The main reducer blank 5 is provided with a blank upper disc 7, which is movably fitted and clamped with the arc bayonet 4. The main reducer blank 5 is also provided with a top bearing portion 8. The rotation limit positioning seat 3 is provided with a positioning support slide 9. The rotation limit assembly includes a positioning center slider 10, which is slidably installed inside the positioning support slide 9. A limiting claw 11 is fixedly installed on the positioning center slider 10, and the limiting claw 11 is movably fitted with the inner wall of the top bearing portion 8.

[0040] The main reducer blank 5 is simultaneously clamped on multiple arc snap-fits 4 through the upper disc 7 of the blank, and the number of arc snap-fits 4 is not less than three, so as to fix the rotation center of the main reducer blank 5, and then the limiting claw 11 slides inside the positioning support slide 9 through the positioning center slider 10 to achieve insertion between the two inner walls of the top bearing part 8, thereby realizing the rotation limit of the main reducer blank 5.

[0041] The side pressure supporting mechanism includes a side positioning block 12, which is bolted to the positioning base plate 1, and a clamping pad 13 is bolted to the top of the side positioning block 12. A limiting screw 14 is fixedly installed on the top of the side positioning block 12, and a pressure plate 15 is movably mounted on the limiting screw 14. An adjusting groove 16 is provided on the pressure plate 15, and the limiting screw 14 is movably matched with the adjusting groove 16. The bottom of one end of the pressure plate 15 is movably fitted with the clamping pad 13, and the bottom of the other end of the pressure plate 15 is fixedly installed with an arc-shaped clamping block 17, and the bottom of the arc-shaped clamping block 17 is movably pressed and fitted with the bearing hole 6.

[0042] The side pressure supporting mechanism is achieved by screwing a nut on the limit screw 14. When the nut screw descends, it can drive the pressure plate 15 to descend, and then drive the arc-shaped clamping block 17 to fit and press the bottom of the bearing hole 6, thereby fixing the main reducer. The adjustment groove 16 can facilitate the movement of the pressure plate 15 and the removal and placement of the main reducer. The arc-shaped clamping block 17 can increase the clamping contact area, further improving the positioning accuracy and stability of the main reducer.

[0043] The utility model clamps and positions the main reducer blank 5 through a fixed arc bayonet 4, fixes the horizontal angle and the center position of the circle, limits the rotation angle of the main reducer through a rotation limit assembly, and then presses the main reducer blank 5 through a side pressure supporting mechanism, thereby shortening the time for aligning the rotation direction of the main reducer blank 5, improving the alignment accuracy of the rotation direction of the main reducer blank 5, facilitating the tightening operation of the operator, and improving the processing accuracy of the indexing hole of the main reducer blank 5 and the threaded hole of the bearing cover.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
