When clamping, the air chamber support is first installed on the chuck, and then the swing arm cylinder is started. The swing arm cylinder presses the air chamber support to the predetermined position of the axle body through the chuck, and then the air chamber support is welded to the axle body. Compared with the traditional manual positioning method, the positioning tool clamps the air chamber support through the chuck, and then accurately presses the air chamber support to the predetermined position of the axle body through the swing arm cylinder to prevent malfunction during welding. The overall structure is simple and reliable, which greatly improves the welding quality and welding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Figures 1 to 5An embodiment of the positioning tooling for welding the axle body and the air chamber support of the present invention is shown, comprising a frame 1, a fixed arm 2, a swing arm cylinder 3 and a chuck 4 for clamping the air chamber support, the fixed arm 2 is mounted on the frame 1, the swing arm cylinder 3 is mounted on the fixed arm 2, and the chuck 4 is mounted on the output end of the swing arm cylinder 3. During clamping, the air chamber support is first mounted on the chuck 4, and then the swing arm cylinder 3 is started, and the swing arm cylinder 3 presses the air chamber support to the predetermined position of the axle body through the chuck 4, and then the air chamber support is welded to the axle body. Compared with the traditional manual positioning method, the positioning tooling realizes the clamping of the air chamber support through the chuck 4, and then the air chamber support is accurately pressed to the predetermined position of the axle body through the swing arm cylinder 3 to prevent malfunction during welding. The overall structure is simple and reliable, which greatly improves the welding quality and welding efficiency.

[0025] In this embodiment, the chuck 4 includes a mounting platform 41 and a clamping platform 42. The mounting platform 41 is mounted on the output end of the swing arm cylinder 3, and the clamping platform 42 is mounted on the mounting platform 41. In this structure, the mounting platform 41 is connected to the output end of the swing arm cylinder 3 to provide a mounting base for the clamping platform 42. The clamping platform 42 is used to clamp the air chamber support, and its structure is simple and reliable.

[0026] In this embodiment, the mounting platform 41 includes an upper fixing block 411, a lower fixing block 412 and a pressure spring 413. The upper fixing block 411 is mounted on the output end of the swing arm cylinder 3, the lower fixing block 412 is connected to the upper fixing block 411 through the pressure spring 413, and the clamping platform 42 is mounted on the lower fixing block 412. In this structure, when pressed down for positioning, the upper fixing block 411 will further press the lower fixing block 412 through the pressure spring 413, so that the clamping platform 42 generates further pressing force, which can ultimately improve the welding quality.

[0027] In this embodiment, a guide column 414 is provided between the upper fixing block 411 and the lower fixing block 412. The guide column 414 ensures stability and smoothness during downward pressing.

[0028] In this embodiment, the clamping platform 42 includes a clamping block 421 and a pair of clamping plates 422 disposed on the clamping block 421. The clamping block 421 has a concave cavity at the bottom. When clamping, the air chamber support is located in the concave cavity and is clamped by the pair of clamping plates 422.

[0029] In this embodiment, a spring pin 423 for tightening the air chamber support is installed on the clamp block 421. When the air chamber support is clamped, the spring pin 423 is avoided to ensure that the air chamber support can enter the concave cavity, and then the spring pin 423 pops out to tighten the air chamber support, further improving the clamping force of the air chamber support.

[0030] In this embodiment, the clamping platform 42 is provided with a handle 5 for facilitating the resetting of the swing arm cylinder 3. When welding is completed, the operator pulls the handle 5 upward to reset the swing arm cylinder 3.

[0031] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
