The working principle of the clamping device with the side edge adjusted;

initial state: the limit baffles 24 are farthest away; when the device works, firstly, a PCB is placed on the marble bedplate 20, then the pair of limiting baffles 24 are close to each other until the PCB is clamped, so that the limiting clamping of the PCB is completed, and the device is suitable for limiting clamping of PCBs with various sizes;

the marble bedplate 20 has high overall strength because no groove is formed on the marble bedplate 20;

meanwhile, due to the existence of the four lifting cylinders 11 and the rollers 12 on the four lifting cylinders, the marble bedplate 20 can be in a horizontal state, and the influence on the production and processing of subsequent workpieces due to the inclination of the upper end surface of the marble bedplate 20 caused by manufacturing and installation errors is avoided.
