[0002] Projection welding is a highly efficient welding method that can perform multiple welding points simultaneously. It can be used to replace arc welding, brazing and bite welding. This method has a high processing speed and consumes no other energy except electricity, which is a great feature. Compared with spot welding, projection welding is different in that projections are pre-processed on the plate, or the profiles and chamfers on the weldment that can concentrate the current are used as the mutual contact points during welding.
[0003] The existing projection welding fixture with a positioning function for shock absorbers, when installed and used, has no adjustment function on the positioning and fixing structure, so it can only fix a single type of shock absorber, resulting in fewer usage scenarios of the device; since there is no cooling structure, the welding strength of the standard parts themselves is reduced under the high temperature and pressure generated by the power on during welding, affecting the product quality or even scrapping it, which has a certain adverse effect on people's use process. In order to address the deficiencies of the prior art, we propose a projection welding fixture with a positioning function for shock absorbers. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-4 As shown, a projection welding fixture with a positioning function is used for a shock absorber, a fixing rod 6 and a U-shaped fixing frame 17 are threadedly connected, a silicone pad is arranged on the inner wall of the U-shaped fixing frame 17, and a workbench 1 and a second fixing frame 11 are welded.
[0023] Pull open the movable block 15, the length telescopic rod 10 and the spring 9 are stretched, and the shock absorber is placed in the cavity formed by the two sets of U-shaped fixing frames 17. Then let go, the spring 9 generates a rebound force, driving the length telescopic rod 10 and the movable block 15 to move to the left, so that the two sets of U-shaped fixing frames 17 are tightly fixed on the outer surface of the shock absorber. At the same time, according to the adaptation of the shock absorber diameter, the model of the U-shaped fixing frame 17 is replaced so that the curvature of the U-shaped fixing frame 17 is kept close to the shock absorber, and the device can fix shock absorbers of different diameters.
[0024] like Figure 1-4 As shown, a projection welding fixture with a positioning function for a shock absorber, the lower electrode 13 and the upper electrode 8 have the same center line as the circular hole set inside the workbench 1, and the diameter of the circular hole is smaller than the diameter of the U-shaped fixing frame 17.
[0025] The cylinder 4 drives the connecting frame 5 to descend, and the four sets of height telescopic rods 14 maintain the balance of the connecting frame 5. Then the upper electrode 8 and the lower electrode 13 are energized to counterattack, and arc welding is performed on the shock absorber. Subsequently, the convex welding of the shock absorber is completed. After removing the shock absorber, the length telescopic rod 10 and the spring 9 return to normal state, so that the movable block 15 moves to the left. To a certain extent, the movable block 15 can scrape off the welding slag on the upper surface of the workbench 1, and the water inlet 2 is connected to the water source, so that the cooling water pipe 3 can cool the upper electrode 8.
[0026] How it works
[0027] It should be noted that the utility model is a projection welding fixture with a positioning function for a shock absorber. When in use, the movable block 15 is pulled open, the length telescopic rod 10 and the spring 9 are stretched, and the shock absorber is placed in the cavity formed by the two groups of U-shaped fixing frames 17. Then let go, the spring 9 generates a rebound force, driving the length telescopic rod 10 and the movable block 15 to move to the left, so that the two groups of U-shaped fixing frames 17 are tightly fixed on the outer surface of the shock absorber. At the same time, according to the adaptation of the shock absorber diameter, the model of the U-shaped fixing frame 17 is replaced so that the curvature of the U-shaped fixing frame 17 remains close to the shock absorber, and the device can fix shock absorbers of different diameters.
[0028] The cylinder 4 drives the connecting frame 5 to descend, and the four sets of height telescopic rods 14 maintain the balance of the connecting frame 5. Then the upper electrode 8 and the lower electrode 13 are energized to counterattack, and arc welding is performed on the shock absorber. Subsequently, the convex welding of the shock absorber is completed. After removing the shock absorber, the length telescopic rod 10 and the spring 9 return to normal state, so that the movable block 15 moves to the left. To a certain extent, the movable block 15 can scrape off the welding slag on the upper surface of the workbench 1, and the water inlet 2 is connected to the water source, so that the cooling water pipe 3 can cool the upper electrode 8.
