[0026] Compared with the prior art, the quick-change welding fixture for hydraulic shock absorber components described in this embodiment of the invention has the following advantages:

[0027] In the quick-change fixture for welding hydraulic damper components provided in this embodiment of the invention, the replacement of different fixtures is achieved simply by loosening the tightening screw to remove the tapered fixture and quickly replace it with other fixtures. After replacement, only tightening the tightening screw is required to complete the replacement. In other words, the quick-change fixture for welding hydraulic damper components provided in this embodiment of the invention adopts a quick-change fixture structure with a 16° tapered angle. By fixing it with the tightening screw, this positioning method eliminates the need for repeated fixture checks after installation, effectively improving production efficiency by 30%. The symmetry of the welded components is also significantly improved. That is, after installation, the damper weld can be performed, greatly improving the welding clamping efficiency. Due to the reasonable tapered structure, the symmetry and parallelism of the welded products are also improved.

[0028] In practical applications, such as Figures 1-4 As shown, the aforementioned follower rotary flange 7 can be mounted on the fixture body 6 via bearing 71.

[0029] Among them, such as Figures 1-4 As shown, the interior of the aforementioned follower rotary flange 7 has a 16° tapered hole. The quick-change tapered clamp 8 is connected to the tapered hole of the follower rotary flange 7 through the 16° tapered surface, and the contact area is not less than 75%. Therefore, based on the characteristics of the tapered connection, its centering characteristics and supporting force make the tapered connection stable and reliable, and the connection accuracy can be guaranteed without additional testing.
