[0021] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12, Figure 13 , Figure 14 , Figure 15 As shown in Figure 13 , Figure 14 , and Figure 15 , a welding device for machining an outer cylinder of an automotive shock absorber includes a base 1. A left clamp 3 for clamping the outer cylinder is provided at one end of the base 1, and a right clamp 2 for clamping an end cap 19 is provided at the other end. A welding assembly 4 is provided on one side of the base 1, and a grinding assembly 5 is provided on the other side. The grinding assembly 5 includes a driving part, and a mounting plate 14 is provided on the driving part. A welding torch 15 is provided on the mounting plate 14. The driving part can drive the welding torch 15 to move in the horizontal and vertical directions to approach or move away from the weld seam. The butt joint detection assembly includes a first guide rod 16 and a second guide rod 17, which are symmetrically arranged on both sides of the welding torch 15. The first guide rod 16 slidably penetrates through the mounting plate 14. A first guide wheel 1601 is provided at one end close to the left clamp 3, and a limit plate 18 is fixedly provided at the other end. A threaded rod 21 is screwed on the limit plate 18. One end of the threaded rod 21 is rotatably connected to the mounting plate 14, and a end cap is provided at the other end. The second guide rod 17 slidably penetrates through the mounting plate 14 and also slidably penetrates through the limit plate 18. A second guide wheel 1701 is provided at one end close to the left clamp 3, and an end cap 19 is provided at the other end. A spring 20 is provided between the end cap 19 and the limit plate 18. A laser emitter 23 is provided on the first guide wheel 1601, and a laser receiver 22 for receiving the optical signal emitted by the laser emitter 23 is provided on the second guide wheel 1701. Both the laser emitter 23 and the laser receiver 22 are connected to an external control system. The external control system judges the butt joint accuracy between the outer cylinder and the cylinder end through the optical signal transmitted by the laser emitter 23 and the laser receiver 22. When the butt joint detection assembly detects a poor butt joint accuracy between the outer cylinder and the cylinder end, the external control system will adjust the position of the left clamp 3 to adjust the butt joint position between the outer cylinder and the cylinder end.

[0022] In this embodiment, the worker clamps the shock absorber outer cylinder on the left clamp 3 and clamps the cylinder end on the right clamp 2. After clamping, the outer cylinder and the cylinder end are butted. After butting, the driving part is controlled to adjust the position of the welding torch 15 to align the welding torch 15 with the weld seam, preparing for circumferential welding. Among them, through the provided butt joint detection assembly, the operator adjusts the position of the limit plate 18 by rotating the screw on the end cap, thereby changing the length of the first guide rod 16 extending from the mounting plate 14. In this way, the distance between the tip of the welding torch 15 and the weld seam can be flexibly adjusted according to specific welding requirements to achieve the best welding effect. Then, the driving part adjusts the position of the welding torch 15 to make the welding torch 15 perpendicular to the weld seam and make the first guide rod 16 and the second guide rod 17 abut against both sides of the weld seam. Before welding, the left fixture 3 and the right fixture 2 will first drive the clamped outer cylinder and the cylinder end to slowly rotate one week. During this process, if the docking accuracy between the outer cylinder and the cylinder end is high, at this time, when the first guide rod 16 and the second guide rod 17 move along their surfaces, they will always remain on the same horizontal line, and the laser signal emitted upward by the laser emitter 23 received by the laser receiver 22 will remain constant; on the contrary, if the docking accuracy is insufficient, the laser signal received by the laser receiver 22 will deviate, indicating the existence of an alignment error. When it is detected that the docking accuracy between the outer cylinder and the cylinder end is poor, the external control system will adjust the position of the left fixture 3 to correct the docking position of the outer cylinder and the cylinder end, eliminate the deviation, ensure the docking accuracy of the two, and thus ensure the welding effect.
