e: when the front position and the rear position of the welding table body (3) need to be finely adjusted, firstly, the rotary table (14) is rotated to drive the rotary rod (11) and the gear (12) to start rotating, the gear (12) and the gear bar (13) are meshed with each other, at the moment, the gear bar (13) drives the first support (4) and the welding table body (3) to move in the front-rear direction, meanwhile, the second distance measuring sensor (16) is started, the distance between the second reflector plate (15) and the second distance measuring sensor can be measured in real time, then the moving distance between the first support (4) and the welding table body (3) during the front-rear fine adjustment is calculated according to the measured result of the first distance measuring sensor (9), and the front-rear position of the welding table body (3) is adjusted according to the measured distance;
f: after the position of the welding table body (3) is adjusted, the first nut (25) and the second nut (26) need to be rotated respectively and tightly attached to the surfaces of the first support (4) and the second support (5) respectively, and then the laser generator (2) can be started to weld the objects.
