During clamping, first start the driving part 4 to drive the sliding table 6 to move according to the angle required to be formed between the spring plate seat and the axle housing, and the sliding table 6 will push the swing seat 3, and the swing seat 3 is constrained by the rolling support group 5 and swings on the rolling support group 5, so that the swing seat 3 can swing to the required angle. At this time, the positioning plate 7 and the fixed arm 8 will form the adjusted angle, and then the axle body is positioned on the positioning plate 7, and the axle body is also deflected to the adjusted angle, and then the four plates of the spring plate seat are surrounded on the axle housing and welded in sequence to form a covering structure; finally, the air chamber support is installed on the chuck 10, and then the swing arm cylinder 9 is started, and the swing arm cylinder 9 presses the air chamber support to the predetermined position of the axle body through the chuck 10, and then the air chamber support is welded to the axle body. Compared with the traditional manual positioning method, the positioning tooling pre-adjusts the angle of the swing seat 3 and the positioning plate 7, so that the angle deflection is formed when the axle body is positioned, ensuring that the spring plate seat and the axle housing finally form an angle, realizing precise angle positioning, and the overall structure is simple and reliable, which greatly improves the welding quality and welding efficiency; at the same time, the positioning tooling clamps the air chamber support through the chuck 10, and then accurately presses the air chamber support to the predetermined position of the axle body through the swing arm cylinder 9 to prevent malfunction during welding.

[0035] In this embodiment, the swing seat 3 includes a support plate 31 and arc-shaped swing plates 32 arranged on both sides of the support plate 31. The arc-shaped surface of the arc-shaped swing plate 32 is rollingly connected with the corresponding rolling support group 5. The support plate 31 is movably connected with the sliding platform 6. The positioning plate 7 is installed on the support plate 31. In this structure, the support plate 31 is used to install the positioning plate 7. The arc-shaped swing plates 32 on both sides are affected by the sliding platform 6 and swing to a desired angle on the rolling support group 5. Its structure is simple and ingenious.

[0036] In this embodiment, a T-shaped plate 311 is provided at the bottom of the support plate 31, a U-shaped hinge ear 61 is provided at the top of the sliding platform 6, and the T-shaped plate 311 is inserted into and movably connected to the U-shaped hinge ear 61. In this structure, the swing function of the arc swing plate 32 is realized through the movably connected U-shaped hinge ear 61 and the T-shaped plate 311.

[0037] In this embodiment, vertical waist-shaped holes 611 are provided on the two ear plates of the U-shaped hinge ear 61, and a pin shaft capable of vertical movement is installed in the vertical waist-shaped hole 611, and the T-shaped plate 311 is connected to the pin shaft. Since the sliding platform 6 is linearly operated and constrained by the rolling support group 5, the swing of the arc-shaped swing plate 32 can be decomposed into translation and ascending motion, so the pin shaft can move vertically in the vertical waist-shaped hole 611, and finally the swing of the arc-shaped swing plate 32 is formed, which has a simple structure and ingenious design.

[0038] In this embodiment, the rolling support group 5 includes a plurality of support legs 51 mounted on the frame 1, and a roller 52 is mounted on the top of each support leg 51. Each support leg 51 is evenly distributed at the bottom of the arc-shaped swing plate 32 on the corresponding side, and the roller 52 is in contact with the corresponding arc surface. In this structure, when the arc-shaped swing plate 32 is subjected to thrust, it will swing on the roller 52, ensuring the stability and smoothness of the swing.

[0039] In this embodiment, the rolling support group 5 further includes a limiting support platform 53 and a limiting roller 54 mounted on the limiting support platform 53. An arc-shaped limiting hole 321 is provided on the arc-shaped swing plate 32. The limiting support platform 53 is mounted on the frame 1. The limiting roller 54 extends into the arc-shaped limiting hole 321. In this structure, the limiting function of the limit position of the arc-shaped swing plate 32 is realized through the constraints of the limiting roller 54 and the arc-shaped limiting hole 321, which plays a certain protective role.

[0040] In this embodiment, a plurality of clamping platforms 71 for positioning the axle body are arranged on the positioning plate 7. The clamping platforms 71 are used to cooperate with the axle body for positioning to prevent the axle body from malfunctioning during welding.

[0041] In this embodiment, the driving member 4 includes a motor 41 and a screw nut transmission pair 42. The motor 41 is mounted on the fixed seat 2, and the screw nut transmission pair 42 is mounted at the output end of the motor 41 and connected to the sliding table 6. In this structure, the rotational motion of the motor 41 is converted into the linear motion of the sliding table 6 through the screw nut transmission pair 42. The linear motion of the sliding table 6 is constrained by the rolling support group 5 and the cooperation between the pin and the vertical waist hole 611, and finally forms the swing of the arc swing plate 32.

[0042] In this embodiment, the chuck 10 includes a mounting platform 101 and a clamping platform 102. The mounting platform 101 is mounted on the output end of the swing arm cylinder 9, and the clamping platform 102 is mounted on the mounting platform 101. In this structure, the mounting platform 101 is connected to the output end of the swing arm cylinder 9 to provide a mounting base for the clamping platform 102, and the clamping platform 102 is used to clamp the air chamber support, and its structure is simple and reliable.

[0043] In this embodiment, the mounting platform 101 includes an upper fixing block 1011, a lower fixing block 1012 and a pressure spring 1013. The upper fixing block 1011 is mounted on the output end of the swing arm cylinder 9. The lower fixing block 1012 is connected to the upper fixing block 1011 through the pressure spring 1013. The clamping platform 102 is mounted on the lower fixing block 1012. In this structure, when pressed down for positioning, the upper fixing block 1011 will further press the lower fixing block 1012 through the pressure spring 1013, so that the clamping platform 102 generates further pressing force, which can ultimately improve the welding quality.

[0044] In this embodiment, a guide column 1014 is provided between the upper fixing block 1011 and the lower fixing block 1012. The guide column 1014 ensures stability and smoothness during downward pressing.

[0045] In this embodiment, the clamping platform 102 includes a clamping block 1021 and a pair of clamping plates 1022 disposed on the clamping block 1021. The clamping block 1021 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 1022.

[0046] In this embodiment, a spring pin 1023 for tightening the air chamber support is installed on the clamping block 1021. When the air chamber support is clamped, the spring pin 1023 is avoided to ensure that the air chamber support can enter the concave cavity, and then the spring pin 1023 pops out to tighten the air chamber support, further improving the clamping force of the air chamber support.

[0047] In this embodiment, the clamping platform 102 is provided with a handle 11 for facilitating the resetting of the swing arm cylinder 9. When welding is completed, the operator pulls upwards through the handle 11 to reset the swing arm cylinder 9.
