Then, the second servo motor 507 is started to drive the second threaded rod 506 to rotate. The rotational motion of the second threaded rod 506 will be converted into a linear motion of the sliding block 505, driving the pressure plate 504 to move downward, squeezing the workpiece and fixing it, completing the positioning of the workpiece, and making the clamping of the clamping plate 304 more stable.
