DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.
[0020] According to Figures 1 to 4 As shown, a bending and welding tooling assembly for the wire seat of the rear axle housing includes a welding template 1. The welding template 1 includes a first plate body, a second plate body, and a third plate body that are integrally connected. The first plate body is arranged in a cross shape, and the second plate body and the third plate body are respectively arranged at both ends of the first plate body. The second plate body and the third plate body are arranged in an L shape.
[0021] The inner side of the first plate body is provided with positioning posts 3, and the positioning posts 3 are inserted into the threaded holes of the large flange. The outer side of the first plate body is provided with a handle 4. The distance between the second plate body and the handle 4 is set to be greater than the distance between the third plate body and the handle 4, and the height of the third plate body is set to be greater than the height of the second plate body.
