The secondary positioning blocks 6 have corresponding positioning blocks on both sides of their outer walls. The system is equipped with a slide rail groove 7, with a side positioning block 8 slidably connected to one side of the slide rail groove 7. A fourth workpiece 15 is installed on the outer side of the side positioning block 8. Fixed seats 9 are symmetrically installed on the top outer wall of the base plate 1, and the fixed seats 9 are located on both sides of the side positioning block 8.

A clamping block 3, a main positioning block 5, and a secondary positioning block 6 are installed on the top outer wall of the main slide rail 4, and the bottom end of the clamping block 3 is slidably connected to the outer wall of the main slide rail 4. The secondary positioning block 6 is shaped like a mountain, and the protrusion of the secondary positioning block 6 is located on the outer side of the second workpiece 13. On the wall, when the main cylinder 2 is activated, the main cylinder 2 pushes the clamping block 3 to slide back and forth on the slide rail, and the second workpiece 13 can be pre-positioned by the mountain-shaped auxiliary positioning block 6; there are two slide rail grooves 7, and the slide rail grooves 7 are symmetrical from left to right, and the auxiliary positioning block 6 can be used to assist in the positioning of the slide rail grooves 7; one side of the side positioning block 8 is slidably connected to the outer wall of the slide rail groove 7, and the side positioning block 8 can be used to slide along the slide rail groove 7, thereby assisting in the positioning of the first workpiece 12; there are two L-shaped connecting plates 11, and the L-shaped connecting plates 11 are symmetrical from left to right, and one side of the L-shaped connecting plate 11 is fixed to the outer wall of the auxiliary positioning block 6, which facilitates the positioning of the L-shaped connecting plate by the auxiliary positioning block 6. 11.

The auxiliary positioning block 6 assists in positioning the first workpiece 12. Then, the auxiliary cylinder 10 is started to drive the L-shaped connecting plate 11 to move. The L-shaped connecting plate 11 drives the side positioning block 8 to move left and right along the slide rail in the slide rail groove 7. The fourth workpiece 15 is pushed by the auxiliary positioning block 6 to approach the pre-positioned second workpiece 13.
