[0001] This utility model relates to the field of bridge housing production technology, and in particular to a fixture for grinding and fixing the triangular plate of a bridge housing. Background Technology

[0002] Automotive axle housings can be classified into three types according to their manufacturing processes: integral cast axle housings, steel plate stamping and welding axle housings, and expanded steel plate axle housings. Among these, steel plate stamping and welding axle housings are the most widely used. A steel plate stamping and welding axle housing consists of an upper axle plate, a lower axle plate, a leaf spring seat, a half-shaft sleeve, a rear cover, and a main reducer housing. The upper axle plate, lower axle plate, triangular plate, leaf spring seat, and half-shaft sleeve are welded together to form a welded drive axle housing. It has advantages such as light weight, good impact resistance, and low cost.

[0003] Before welding, the two arc-shaped connecting surfaces of the triangular plate need to be ground. The current grinding method is: the worker holds the triangular plate with pliers in one hand and grinds it with a hand-held grinder in the other hand. Grinding needs to be done one by one, which is inefficient and cannot meet production needs.

[0004] Based on the above problems, the inventors proposed a grinding fixture for bridge shell triangular plates, which can effectively improve grinding efficiency by combining the structural characteristics of triangular plates. Summary of the Invention

[0015] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0016] like Figure 1 , 2As shown, this utility model includes a processing table, with triangular plates 9 stacked on the panel 1 of the processing table. Each triangular plate 9 includes an arc-shaped positioning surface 15 and two arc-shaped connecting surfaces 14. A positioning mechanism for positioning the triangular plates 9 is provided on the panel 1. The positioning mechanism includes an arc-shaped positioning plate 7 and two adjustable positioning rods 8. The arc-shaped positioning plate 7 is perpendicularly fixed to the panel 1, and the curvature of the arc-shaped positioning plate 7 matches the curvature of the arc-shaped positioning surface 15. The arc-shaped positioning surface 15 rests against the arc-shaped positioning plate 7. The two positioning rods 8 are used to position the two arc-shaped connecting surfaces 14 respectively.

[0017] In this embodiment, a fixing mechanism for pressing the triangular plate 9 is provided on the top surface of the arc-shaped positioning plate 7. The fixing mechanism includes a mounting plate 16, a rotary pressing cylinder 13, and a pressing plate 10.

A through hole is provided on the swing arm 12 of the rotary pressing cylinder 13, and a screw 11 passes through the through hole. The lower end of the screw 11 is fixed to the pressing plate 10. An upper adjusting nut and a lower adjusting nut are threaded onto the screw 11. The upper adjusting nut and the lower adjusting nut are located on the upper and lower sides of the swing arm 12, respectively. The height of the pressing plate 10 can be adjusted by coordinating the upper adjusting nut and the lower adjusting nut.

[0018] In this embodiment, the panel 1 is provided with guide holes 6 corresponding to each positioning rod 8 and through which the positioning rod 8 passes. Each positioning rod 8 is provided with a drive mechanism for driving its lifting and lowering.

[0019] In this embodiment, a support frame 2 is provided below the panel 1 for support, and a horizontal support plate 4 is provided on the support frame 2. The driving mechanism includes a lifting cylinder 3, the cylinder seat of the lifting cylinder 3 is fixed to the horizontal support plate 4, the piston rod end of the lifting cylinder 3 is connected to a fixed seat 5, and the positioning rod 8 is fixed to the fixed seat 5.
