At the same time, the air intake holes 13 facilitate heat dissipation inside. Through the wire 14 and the operator 15, the start and operating power between the servo motor 3, the electric telescopic rod 202, and the laser welding equipment 204 can be respectively controlled. Through the observation window 16, it is convenient to observe the welding situation.

[0045] Refer to Figure 1 、 Figure 2 and Figure 3 , on the right side of the front end of the cabinet door 207, there is a fixed connection of a handle 18. A keyhole 19 is provided on the front side of the handle 18. The handle 18 facilitates opening the cabinet door 207.

[0047] Working principle: Before using this device, first, place the oil cylinder to be welded on the top of the rotating disk 5 above the operation counter 1. Then start the servo motor 3 to drive the rotating disk 6 to rotate. During the initial rotation stage of the rotating disk 6, the clamping block 8 rotates synchronously. With the cooperation of the arc-shaped groove 7 and the groove 9, the clamping block 8 moves towards the central area of the rotating disk 5. When the clamping block 8 is in close contact with the surface of the oil cylinder to be welded, the movement of the clamping block 8 immediately stops. At this time, through the interaction between the groove 9 and the clamping block 8, the rotating disk 5 starts to rotate to ensure that the oil cylinder is firmly clamped. Once the oil cylinder is successfully clamped, the welding operation can be started. After the welding operation is completed, just start the servo motor 3 in reverse, and the clamping block 8 will move away from the center of the rotating disk 5, thus releasing the clamping of the oil cylinder and completing the entire work process. And through the protection mechanism 2, when the oil cylinder is placed on the rotating disk 5, start the electric telescopic rod 202 to make the sliding block 206 slide on the L-shaped chute 205, and then rotate the protection cabinet 203 to a specific angle to cover the oil cylinder for welding. During this process, the laser welding device 204 is started to perform the welding operation on the oil cylinder. When it is necessary to check the welding during the welding operation, the welding condition of the oil cylinder can be checked by opening the cabinet door 207. After the welding is completed, the electric telescopic rod 202 contracts, and the sliding block 206 retracts accordingly, driving the structure above it to first move vertically upward to the top of the fixed column 10, and then rotate leftward. At the same time, the rotating block 201 also rotates accordingly, and finally the protection cabinet 203 is removed, thus ensuring that the operator is protected from strong light during the welding process.
