[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1-5 A positioning device for welding the rear cover of an axle housing includes a base plate 1, a support member 2 fixedly installed in the middle of the base plate 1 for supporting the middle section 51 of the axle housing 5, a rear cover positioning component 3 fixedly installed on one side of the support member 2 for positioning the rear cover 6 fastened to the middle section 51 of the axle housing 5, and positioning components 4 fixedly installed on both sides of the base plate 1 for positioning the shaft heads 52 at both ends of the axle housing 5.

[0021] It should be noted that the base plate 1 is fixedly connected to the welding workbench, which should be equipped with corresponding clamps to clamp and fix the bridge shell 5, i.e., the bridge tube 53, during welding.

[0022] In this utility model, the support member 2 includes a pad 21 and a support plate 22 for supporting the middle section 51. The pad 21 is fixedly installed in the middle of the upper surface of the base plate 1, and the support plate 22 is fixedly installed on the pad 21 and parallel to the base plate 1.

[0023] In this utility model, the top of the rear cover 6 is integrally connected to a connecting seat 7 for connecting the air chamber support, and the connecting seat 7 is provided with a first screw hole 8 (the screw hole is used to connect the air chamber support).

[0024] In this utility model, the rear cover positioning component 3 includes a bracket 31 and a positioning frame 32. The bracket 31 is fixedly installed on one side of the support plate 22. The positioning frame 32 includes a mounting part 321 and a positioning part 322 that are fixedly connected. The mounting part 321 is fixedly installed on the top of the bracket 31. The positioning part 322 extends to the top of the connecting seat 7. The extended end of the positioning part 322 is provided with a second screw hole (not shown in the figure). A positioning bolt 9 is screwed into the second screw hole and the first screw hole 8 from top to bottom in sequence to achieve positioning and temporarily fix the rear cover 6.

[0025] In this utility model, the positioning component 4 includes a support 41 and a positioning block 42. The support 41 is fixedly installed on one side of the base plate 1, and the positioning block 42 is detachably installed on the front side of the support 41 and its position on the support 41 is adjustable.

[0026] In this utility model, the positioning block 42 includes a mounting block 421 and a positioning protrusion 422 fixedly connected to the front side of the mounting block 421. The front side of the positioning protrusion 422 abuts against the outer circular surface of the corresponding shaft head 52, thereby positioning the bridge housing 5 and keeping the base plate 1 and the bridge housing 5 on the same center line, i.e., aligned.

[0027] In this utility model, the upper and lower ends of the support 41 are respectively provided with horizontally extending strip grooves 10, and the upper and lower ends of the mounting block 421 are respectively provided with third screw holes 11. Bolts (not shown in the figure) pass through the corresponding third screw holes 11 and strip grooves 10 from front to back and extend out. The extended end of the bolt is screwed with a locking nut (not shown in the figure).

[0028] Therefore, by tightening the locking nut, the locking nut abuts against the rear side of the support 41, and the nut end of the bolt abuts against the front side of the mounting block 421, thereby fixing the positioning block 42 to the front side of the support 41 and making it detachable.

[0029] By loosening the locking nut, the fixing of the positioning block 42 is released, and the bolt can be moved left and right along the strip groove 10, thereby achieving the purpose of moving the positioning block 42 left and right, thus realizing the adjustment of the position of the positioning block 42 on the support 41, and realizing the positioning of shaft heads 52 of different lengths.

[0030] It should be noted that the purpose of adjusting the position of the positioning block 42 on the support 41 is to ensure that the front side of the positioning protrusion 422 abuts against the outer circular surface of the oil seal protrusion of the corresponding shaft head 52 for shaft heads 52 of different lengths. At this time, the base plate 1 and the bridge housing 5 can be reliably kept on the same center line, that is, aligned.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] In use, the middle section 51 of the bridge housing 5 is placed on the support plate 22, and the support plate 22 supports the middle section.

[0033] By finely adjusting the bridge housing 5, the shaft heads 52 on both sides abut against the front sides of the positioning protrusions 422 on both sides respectively. Specifically, the outer circular surface of the oil seal protrusion of the shaft heads 52 on both sides abuts against the front sides of the positioning protrusions 422 on both sides.

[0034] At this point, the base plate 1 and the bridge shell 5 are aligned along the same center line.

[0035] Then, the bridge housing 5, i.e. the bridge tube 53, is clamped and fixed by the fixtures configured on the welding workbench.

[0036] Then, fasten the rear cover 6 onto the middle section 51 of the bridge housing 5.

[0037] Then, screw the positioning bolts 9 into the second screw hole and the first screw hole 8 from top to bottom to achieve positioning and temporarily fix the back cover 6. At this time, the welding operation of the back cover 6 can be carried out.

[0038] After welding is completed, unscrew the positioning bolt 9, remove the axle housing 5, and then perform additional welding on the parts of the rear cover 6 and the middle section 51 that were originally covered by the bracket 31 and positioning frame 32.

[0039] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0040] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
