Problems solved by technology

[0004] The above-mentioned technical solution has the following defects: during the welding process, the jitter generated by the movement of the longitudinal sliding frame and the working platform may cause a gap between the metal frame and the metal plate, failing to fit, when the laser If the irradiated position is not close to each other, it will lead to failure to weld; and foreign objects may not be able to press against the metal frame and metal plate, which will also cause the two to be not close to each other and cannot be welded, which will greatly affect the welding efficiency

Abstract

The invention relates to a laser spot welding machine and a production process of a range hood using the laser spot welding machine, relates to the technical field of welding equipment, including a frame, and the frame is provided with a laser, an observation mechanism, a moving mechanism, and a moving mechanism A workbench is set on the workbench, and a clamping mechanism is arranged on the workbench. The clamping mechanism includes a fixed frame installed on the workbench. Two movable seats are installed on the fixed frame, and the first clamping block is installed on the movable seat. , a second clamping block is slidably arranged on the moving seat, a space for clamping the weldment is formed on the opposite side of the first clamping block and the second clamping block, and a first drive assembly is provided on the fixed frame, and the fixed The frame is provided with a second driving assembly connected with the moving seat. The present invention clamps the weldment by the first clamping block and the second clamping block, realizes the fixation of the weldment, reduces the possibility of gaps in the weldment, reduces the possibility of the laser being unwelded during welding, and improves Improve the quality of welding and reduce the defective rate.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a laser spot welding machine and a production process of a range hood using the laser spot welding machine. Background technique [0002] Laser spot welding is the use of high-energy laser pulses to locally heat materials in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool, thereby welding the same or different materials. together. [0003] Existing laser spot welding machines such as figure 1 As shown, the frame 1 is included, the frame 1 is provided with a horizontal adjustment frame 41, the horizontal adjustment frame 41 is slid to be provided with a longitudinal adjustment frame 42, and the longitudinal adjustment frame 42 is slid to be provided with a workbench 3; the horizontal adjustment frame 41 A lead screw motor is provided inside, and the...
