A fixing mechanism 5 and an adjusting mechanism 6 are disposed on the upper surface of the base 1. The fixing mechanism 5 includes a fixed seat 51 disposed on the upper surface of the base 1, two electric push rods 52 fixedly mounted on the inner top wall of the fixed seat 51, a pressure plate 53 fixedly connected to the output ends of the two electric push rods 52, and a moving mechanism disposed on the upper surface of the base 1. By activating the controller to synchronously operate the two electric push rods 52, the pressure plate 53 can be pushed to stably clamp the sheet metal part. This design ensures a uniform distribution of clamping force, avoiding welding errors caused by unstable clamping.

[0026] Among them, the fixing seat 51 is a hollow frame, and anti-slip rubber is fixedly connected to the inner bottom wall of the fixing seat 51. There are two sets of fixing seats 51 and pressure plates 53.

[0027] Specifically, the moving mechanism includes a mounting box 54 fixedly connected to the top of the base 1, a servo motor 55 fixedly mounted outside the mounting box 54, a bidirectional threaded rod 56 fixedly connected to the output shaft of the servo motor 55, and moving blocks 57 threadedly connected to the left and right sides of the bidirectional threaded rod 56. By adjusting the rotation direction and speed of the servo motor 55 through the controller, the left and right movement and positioning of the moving blocks 57 can be easily realized. The fixed connection between the fixed seat 51 and the moving blocks 57 also allows the position of the fixed seat 51 to be flexibly adjusted to adapt to sheet metal parts of different sizes, improving the versatility and flexibility of the equipment and achieving the advantage of high welding efficiency.

[0028] It should be noted that the bidirectional threaded rod 56 is rotatably connected to the inside of the mounting box 54, and the two fixed seats 51 are respectively fixedly connected to the upper surfaces of the two movable blocks 57. The bottom of the movable block 57 is fixedly connected to a slider extending into the inside of the mounting box 54, and the inside of the mounting box 54 is provided with a sliding groove that matches the slider, and the slider and the sliding groove are slidably connected.

[0029] In this embodiment, the adjustment mechanism 6 includes a guide rail 61 fixedly connected to the top of the base 1, a drive box 62 slidably connected to the outside of the guide rail 61, a reciprocating motor 63 fixedly installed on the outside of the drive box 62, and a gear 64 fixedly connected to the output shaft of the reciprocating motor 63.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, the sheet metal part to be processed is placed between two fixed seats 51. By adjusting the rotation direction and speed of the servo motor 55 through the controller, the left and right movement and positioning of the moving block 57 can be easily realized. The fixed seat 51 and the moving block 57 allow the position of the fixed seat 51 to be flexibly adjusted to adapt to sheet metal parts of different sizes. By starting the synchronous operation of the two electric push rods 52 through the controller, the pressure plate 53 can be pushed to stably clamp the sheet metal part. By starting the reciprocating motor 63 through the controller, the gear 64 is driven to mesh with the toothed plate, making the movement of the drive box 62 on the guide rail 61 more stable. This stable movement helps to reduce vibration and error in the welding process, realizes precise adjustment of the movement speed and position of the laser welding head 4, and ensures the stability and accuracy of the welding process.
