[0022] The rotating assembly 2 includes a fixed column 21, a first motor 23 and a positioning cylinder 24. The fixed column 21 is fixedly installed on the top of the mounting frame 1. A rotating cylinder 22 is rotatably installed on the surface of the fixed column 21. A connecting piece 211 is fixedly installed on the top of the fixed column 21. The rotating cylinder 22 and the positioning cylinder 24 are fixedly connected by a connecting bridge 25. A first connecting rod 27 and a second connecting rod 28 are arranged between the positioning cylinder 24 and the connecting piece 211.
[0023] The clamping assembly 4 includes a fixed shell 41, the top of the fixed shell 41 is fixedly connected to the output end of the electric telescopic rod 3, a second motor is fixedly installed inside the fixed shell 41, the output end of the second motor passes through the bottom of the fixed shell 41 and extends downward, the output end of the second motor is fixedly connected to a rotating ring 42, and a clamping claw 46 is installed at the bottom of the fixed shell 41. Two clamping claws 46 are symmetrically arranged, and the rotating ring 42 is used to provide power for the movement of the clamping claw 46.
[0024] Furthermore, the first motor 23 is fixedly mounted on the mounting frame 1, and the output end of the first motor 23 passes through the top of the mounting frame 1 and extends upward. The output end of the first motor 23 is fixedly connected to a gear 231, and the surface of the rotating cylinder 22 is fixedly connected to a ring gear 221. The gear 231 is meshed with the ring gear 221. The gear 231 and the ring gear 221 cooperate with each other to convert the output power of the first motor 23 into a rotational force for the rotating cylinder 22 to rotate around the fixed column 21.
[0025] Furthermore, a rotating rod 26 is rotatably installed at the center of the positioning cylinder 24, one end of the first connecting rod 27 is hinged to the connecting piece 211, the other end of the first connecting rod 27 is hinged to one end of the second connecting rod 28, the other end of the second connecting rod 28 is fixedly connected to the top of the rotating rod 26, and the bottom end of the rotating rod 26 is fixedly connected to the top of the electric telescopic rod 3. When the rotating cylinder 22, the connecting bridge 25 and the positioning cylinder 24 rotate as a whole around the fixed column 21, the first connecting rod 27 and the second connecting rod 28 cooperate with each other to make the rotating rod 26 rotate synchronously around its own axis, and when the rotating cylinder 22 rotates to ninety degrees around the fixed column 21, the rotating rod 26 completes a one hundred and eighty degree rotation around its own axis.
[0026] Furthermore, a fixed rod 43 is fixedly connected to the surface of the rotating ring 42, and two fixed rods 43 are provided, and the two fixed rods 43 are symmetrically distributed in the center.

The second motor can drive the rotating ring 42 to rotate around its own axis, and the fixed rod 43 and the transfer rod 47 cooperate with each other to convert the rotational force of the rotating ring 42 into a force for the guide block 45 to slide horizontally along the guide groove 44.
[0027] The working principle of the present utility model is as follows: during actual operation, the second motor drives the rotating ring 42 to rotate around its own axis. The rotating ring 42 rotates and drives the two guide blocks 45 to move toward each other along the guide groove 44 through the fixed rod 43 and the transmission rod 47. The two clamping jaws 46 move synchronously toward each other. The clamping jaws 46 clamp the workpiece into position. After that, the output end of the electric telescopic rod 3 shortens upward, and the clamping assembly 4 and the workpiece move upward synchronously as a whole, so that the workpiece leaves the conveyor belt.
[0028] The first motor 23 is turned on, and the first motor 23 drives the rotating cylinder 22 to rotate around the axis of the fixed column 21 through the gear 231 and the ring gear 221. The rotating cylinder 22 rotates and drives the positioning cylinder 24 and the rotating rod 26 to rotate synchronously around the axis of the fixed column 21 through the connecting bridge 25. The electric telescopic rod 3, the clamping assembly 4 and the workpiece rotate synchronously around the axis of the fixed column 21 as a whole. In the process of the positioning cylinder 24 rotating, the first connecting rod 27 and the second connecting rod 28 cooperate with each other to drive the rotating rod 26 to rotate around its own axis. The rotating rod 26 rotates and drives The electric telescopic rod 3, the clamping assembly 4 and the workpiece rotate synchronously around the axis of the rotating rod 26. When the rotating cylinder 22 rotates ninety degrees around the axis of the fixed column 21, the workpiece comes to the top of another conveyor belt. At this time, the workpiece has just rotated one hundred and eighty degrees around the axis of the rotating rod 26. After that, the output end of the electric telescopic rod 3 extends downward to place the workpiece on another conveyor belt. The second motor runs in the opposite direction. Similarly, the two clamping jaws 46 move in directions away from each other and release the clamping of the workpiece. The other conveyor belt can transport the workpiece to subsequent processing equipment.
