The base plate 6 is fixedly installed on the upper part of the frame 1, and the base plate 6 is mounted on the upper part of the base plate 6. The cylinder three 14 is fixedly installed by the vertical support 12, and the lower end of the cylinder three 14 is equipped with a shock-absorbing pad 13, and the lower end of the shock-absorbing pad 13 is opposite to the card seat 11, and the card seat 11 is installed in the middle section of the upper surface of the base plate 6 through the base 10, and the support seat two 9 is installed in the rectangular sliding holes of the base plate 6 on both sides of the card seat 11. The support seat one 8 is installed in the rectangular sliding hole of the base plate 6 outside the support seat two 9. A pull-back plate 15 is provided on the side of the support seat one 8 facing the support seat two 9, and the main shaft of the cylinder two 7 passes through the support seat one 8 to control the pull-back plate 15. The lower parts of the support seat 1 8 and the support seat 2 9 are connected to their respective cylinders 1 5, and the telescopic rod of the cylinder 1 5 passes through the tension plate 18. The cylinder 1 5, the cylinder 2 7 and the cylinder 3 14 are connected to their respective knob manual valves 4, universal mufflers 17 and threaded straight-through 16 through the air pipe 3 and the T-shaped three-way 19. A knob manual valve 4 can control two cylinders at the same time through the threaded straight-through 16 and the air collecting row 2, that is, a knob manual valve 4 can control two cylinders corresponding to the support seat 1 8 or the support seat 2 9 at the same time under the cooperation of the threaded straight-through 16 and the air collecting row 2, so that the support seat 1 8 and the support seat 2 9 can be locked with only two operations. The universal muffler 17 is used to reduce the exhaust sound when the cylinder moves. The cylinder 2 7 and the cylinder 3 14 are connected to the knob manual valve 4 through the air pipe 3.

[0016] The structure of the second embodiment is basically the same as that of the first embodiment, except that a scale is provided on the upper surface of the substrate 6 .

[0017] In order to further optimize the working efficiency of the present application and make the base plate 6 more flat and stable, a leveling pad is provided at the lower part of the frame 1.

[0020] When in use, the staff can move the support seat 18 and the support seat 29 according to the size of the rear axle, and close the knob manual valve 4 corresponding to the cylinder 15 connected to the support seat 18 by twisting it. The high-pressure air will enter the cylinder 15 connected to the support seat 8 under the action of the T-shaped three-way 19 and the air collecting row 2, and continue to pressurize it, so that the cylinder 15 of the support seat 18 contracts and drives the tensioning plate 18 thereon to cooperate with the support seat 18 to clamp the base plate 6, thereby completing the fixation of the support seat 18. Then, by twisting the knob manual valve 4 corresponding to the cylinder 15 connected to the support seat 29 to close it, the high-pressure air will enter the cylinder 15 connected to the support seat 8 under the action of the T-shaped three-way 19 and the air collecting row 2, and continue to pressurize it. The cylinder 15 of the support seat 29 contracts and drives the tensioning plate 18 thereon to cooperate with the support seat 29 to clamp the base plate 6, thereby completing the fixation of the support seat 8. Tighten the base plate 6 to complete the fixation of the support seat 2 9, place the workpiece to be welded on the holder 11, the support seat 1 8 and the support seat 2 9, then control the knob manual valve 4 corresponding to the cylinder 2 7 to let the pullback plate 15 clamp the flange at the end of the rear axle, turn the knob manual valve 4 connected to the cylinder 3 14 to close it, and high-pressure air will enter the cylinder 3 14 under the action of the T-shaped tee 19 to make it extend downward so that the shock-absorbing pad 13 can press the rear axle assembly placed on the holder 11, and then the staff can start the welding work. After welding, turn the knob manual valve 4 connected to the cylinder 3 14 to let the high-pressure air pass through the universal muffler 17 to vent, and then remove the workpiece and weld the next workpiece. If you need to weld rear axles of other sizes, just readjust the positions of the support seat 1 8 and the support seat 2 9.

[0021] In summary, the auxiliary tooling for welding rear axles of electric tricycles of various specifications in the embodiment of the utility model ensures that the force applied to the parts each time is consistent through cylinder control, which greatly improves the stability and consistency of product quality. At the same time, by setting the movable support seat 1 8 and the support seat 2 9, the compatibility with rear axles of various wheelbases is achieved. At the same time, because it has a one-button locking function of the knob manual valve 4, it greatly reduces the time and physical effort wasted by workers in actual production due to frequent replacement and adjustment of tooling, so that production efficiency is improved. In this way, the purpose of using one set of tooling to deal with rear axles of various wheelbases and effectively pressing them in place to ensure product quality can be achieved, which can effectively improve production efficiency.
