Among them, the driven wheel flange is a key component in mechanical equipment, and its welding quality directly affects the safety and stability of the entire equipment. Therefore, it is particularly important to develop an efficient, accurate and stable driven wheel flange welding tooling.

[0003] During traditional driven wheel flange welding, after the driven wheel is installed on the side panel, the flange and the side panel are first bolted together. Since the flange is light, it is easily pulled by the side panel, resulting in inaccurate gap size. The gap size needs to be readjusted, and the adjustment takes a certain amount of time. In addition, the driven wheel is generally painted before being installed on the side panel, and then welded after painting. This increases the difficulty of welding and affects the appearance. Manual touch-up of paint is required, which takes a certain amount of time, resulting in poor work efficiency. Utility Model Content

Since it is prior art, it will not be described in detail in this case. Starting the motor 63 can drive the bidirectional threaded rod 64 to rotate, and the bidirectional threaded rod 64 has self-locking properties.

[0031] Reference Figure 1 , Figure 3 , Figure 4 The support clamping assembly 6 also includes a moving block 65, the rear surface of the moving block 65 is fixedly connected to an adjusting plate 66, and the left surface of the adjusting plate 66 is fixedly connected to a top block 67. The moving block 65, the adjusting plate 66 and the top block 67 will move synchronously.

[0032] Reference Figure 1 - Figure 3 The fixing assembly 5 includes a stopper 51, a positioning block 52 is fixedly connected to the lower surface of the rectangular tube 1, and a positioning bolt 53 is passed through and threadedly connected to the left surface of the positioning block 52. When the positioning bolt 53 is turned, the positioning bolt 53 will move laterally. By turning the positioning bolt 53, the distance between the positioning bolt 53 and the flange 3 can be changed. When the positioning bolt 53 and the flange 3 are in close contact, the flange 3 will be clamped and fixed.

[0033] Reference Figure 1 , Figure 3 , Figure 4 The rectangular tube 1 is located directly above the I-beam 2 , the outer wall of the driven shaft 4 fits the inner wall of the flange 3 , and the right end of the lower surface of the positioning pin 62 fits the upper surface of the positioning plate 61 .
