Compared with ordinary parts, precision parts are more precise and more suitable for industries with high requirements for precision. In the process of precision parts processing, they need to be welded, and a laser welding machine is required for welding.

[0003] The utility model with publication number CN118060711A provides a laser welding machine for precision parts processing, including a slide rail, a slider, and a laser, wherein the slide rail and the slider are slidably matched, and further comprising a welding table. The lower end of the welding table is fixedly connected to a plurality of support legs, the upper end of the welding table is fixedly connected to a gantry, the slide rail is mounted on the upper end of the gantry, the upper end of the slider is fixedly mounted to an electric telescopic rod, and the telescopic end of the electric telescopic rod is fixedly connected to a mounting plate. The present invention provides a limit assembly on the welding table to initially clamp and fix the parts. Since the spacing between the clamping plates is adjustable, parts of different sizes can be fixed, and the versatility is good. The negative pressure box is sucked by a vacuum pump to maintain a negative pressure state in the negative pressure box, generating a pressure difference when the parts are placed up and down. The parts are further fixed on the welding table under atmospheric pressure, which is more conducive to the precise welding of the parts.

[0004] During use, welding slag will fall onto the workbench. If it is not cleaned out in time, the welding slag will stick to the workbench after cooling, making cleaning more difficult and affecting cleaning efficiency.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

At the same time, negative pressure is generated in the negative pressure box. Through the pressure difference between the upper and lower parts of the precision parts, the parts can be further fixed on the workbench 4 to improve its stability. The horizontal driving mechanism 803 and the driving cylinder 801 drive the laser welding head 802 to the appropriate position to weld the precision parts.
