The driving motor 12 drives the rotating shaft 13 and the linkage gear 14 to rotate, so that the linkage gear 14 cooperates with the rack plate 11 on the inner side of the movable beam 2, and drives the clamping seat 15 at the bottom thereof to perform horizontal lateral movement at the bottom of the movable beam 2 to drive the parts to be transported, thereby realizing the automatic loading and unloading operation of the parts, greatly reducing the operator's workload and improving the processing efficiency.

[0020] Reference Figure 1-Figure 3The two ends of the inner side of the main frame 1 are symmetrically provided with slide grooves 3, and the two side surfaces of the movable beam 2 are fixedly installed with sliders 4 adapted to the slide grooves 3.
