[0022] In this embodiment, the clamping frame 1 is rotatably connected to the connecting rod 3, and the connecting structure includes multiple connecting shafts 5. Both ends of the connecting shafts 5 are threaded heads. The connecting shafts 5 are fixedly connected to the chuck 4 by nuts, and the connecting rod 3 is fixedly connected to one of the connecting shafts 5.
[0023] Specifically, when clamping a part, the pulling head 2 is pulled so that the pulling head 2 drives the connecting rod 3 to rotate, thereby driving the chuck 4 to clamp the part. When the opening and closing angle of the chuck 4 needs to be changed, the connecting rod 3 can be fixed with different connecting shafts 5, and the connecting shaft 5 can be inserted into the connecting rod 3. Then, the nut is rotated to clamp and fix the connecting rod 3, so that the position of the chuck 4 can be changed, thereby changing the opening and closing angle of the chuck 4.
[0024] A slot 7 is provided in the chuck 4 , a block 8 is fixed on the clamp plate 6 , the block 8 corresponds to the slot 7 , a plurality of bolts 9 are installed between the chuck 4 and the block 8 , and the chuck 4 and the block 8 are fixedly connected by the bolts 9 .
[0025] Specifically, when the splint 6 is not compatible with the part, the bolt 9 can be removed, and the splint 6 that is compatible with the part can be installed on one side of the chuck 4, and the block 8 can be inserted into the slot 7, and the splint 6 can be fixed by the bolt 9.
[0026] The first pull rod 10 is slidably connected to the second pull rod 12, an electric cylinder 11 is fixed inside the first pull rod 10, the output end of the electric cylinder 11 is fixedly connected to the second pull rod 12, the limiting structure includes a limiting rod 13, the limiting rod 13 is fixedly connected to the clamping frame 1, the electromagnetic suction cup 16 is fixedly connected to the second pull rod 12, a first electrode sheet 14 is fixed on the electromagnetic suction cup 16, a second electrode sheet 15 is fixed on the limiting rod 13, the first electrode sheet 14 corresponds to the second electrode sheet 15, the electromagnetic suction cup 16 includes an electromagnet and a shell, the electromagnet is fixed in the shell, and the shell is fixedly connected to the second pull rod 12.
[0027] Specifically, when it is necessary to clamp a plate-like part, the electric cylinder 11 can be started so that the electric cylinder 11 pushes the electromagnetic suction cup 16 until the electromagnetic suction cup 16 contacts the part, and then the electromagnetic suction cup 16 adsorbs the part, and then the first pull rod 10 is pulled upward, so that the first pull rod 10 pulls the part through the second pull rod 12, and at the same time, the two clamps 6 approach each other. When the part is suspended in the air, the clamp 6 can clamp the part. At this time, the first electrode sheet 14 and the second electrode sheet 15 are powered off, so that the electromagnetic suction cup 16 loses its magnetic force, and the part can be clamped and fixed only by the chuck 4 and the clamp 6.
