The slide seat 19 can be connected to the threaded rod 17 through the connecting hole 20, and is fixed to the output shaft of the driving motor 2 16 through the threaded rod 17. When the driving motor 2 16 is running, the threaded rod 17 can be driven to rotate, so that the slide seat 19 moves on the threaded rod 17 and drives the clamping plate 25 to approach the other end of the workpiece to clamp it. A sliding groove 18 is provided above the threaded rod 17, and two rotating cylinders 21 are provided inside the slide seat 19. The outer walls of the two rotating cylinders 21 are fixedly connected to a block 22, and the inner surface of the rotating cylinder 21 is fixedly connected to a plug plate 26, and the inner surface of the other rotating cylinder 21 is provided with a slot 23. Embodiment 2

[0026] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0027] The rotating drum 3 forms a rotating structure with the fixed box 2 through the clamping block 12 and the turning rail 13. The output shaft of the driving motor 15 is fixedly connected to the rotating drum 3. The rotating drum 3 can be connected to the turning rail 13 inside the fixed box 2 through the clamping block 12. The output shaft of the driving motor 15 is fixed to one end of the rotating drum 3. When the driving motor 15 is started, the rotating drum 3 can be driven to rotate. After the workpiece is clamped in the clamping plate inside the rotating drum 3 and the rotating drum 21, the rotating drum 21 is also driven to rotate through the connection between the workpiece and the rotating drum 3 and the rotating drum 21, so that the workpiece can be driven to rotate together to change the processing surface of the workpiece when necessary.

[0028] The plug-in connection is between the plug-in plate 26 and the slot 23, and the rotating drum 21 is rotatably connected to the slide 19 through the clamping block 22 and the turn rail 13. The plug-in plate 26 is connected to the slot 23, which can facilitate the connection and fixation of the two rotating drums 21, and facilitate the rotation of the rotating drum 21 in the slide 19 and the moving block 9 through the turn rail 13, and can drive the rotating drum 21 to rotate together when the rotating drum 3 drives the workpiece to rotate; the inner wall of the rotating drum 3 is fixedly connected with a connecting rod 8, and four electric push rods 10 are fixed inside one end of the connecting rod 8. The four electric push rods 10 inside one end of the connecting rod 8 push the clamping plate 5 to move outward, so that the clamping groove of the clamping plate 5 is wide, which is convenient for putting one end of the workpiece into the inside of the clamping plate 5 and clamping multiple workpieces.

[0029] The output ends of the four electric push rods 10 are all fixed with a clamping plate 5, the outer wall of the clamping plate 5 is fixed with a spring 4, the inner wall of the clamping plate 5 is bonded with a rubber pad 6, and one end of the clamping plate 5 is provided with an inner groove 11. The electric push rod 10 drives the clamping plate 5 to retract to clamp the workpiece, and the clamping plate 5 can be auxiliary clamped by the elastic action of the spring 4. The rubber pad 6 can increase the friction between the workpiece and the clamping plate to prevent the workpiece from falling; an electric push rod 27 is fixed above the slide 19, and a moving block 9 is fixed to the output end of the electric push rod 27. The slide 19 is provided with an inner groove 11. The electric push rod 27 can drive the moving block 9 to move up and down, and drive the clamping plate 25 to clamp the other end of the workpiece; a spring 24 is fixed to the inner wall of the rotating cylinder 21, and one end of the spring 24 is fixedly connected to the clamping plate 25, and the inner wall of the clamping plate 25 is bonded with a rubber pad 7. By arranging the spring 24 and the clamping plate 25 inside the rotating cylinder 21, the elastic action of the spring 24 can be used to clamp workpieces of different sizes, and the rubber pad 27 can increase the friction between the workpiece and the clamping plate to prevent the workpiece from falling.

[0030] Working principle: the fixed box 2 is connected to the base 1, and the four clamping plates 5 are pushed outward from the inner groove 11 at one end of the clamping plate 5 through the electric push rod 10 on the connecting rod 8 in the fixed box 2, so that the clamping groove is widened, so that the workpiece to be clamped can be placed in the clamping groove, and then the clamping plate 5 is clamped on the workpiece through the retraction of the electric push rod 10 and the elastic action of the spring 4. After one end of the workpiece is clamped, the slide 19 connected to the threaded rod 17 through the connecting hole 20 and the slide groove mouth 18 drives the threaded rod 17 to rotate under the drive of the driving motor 16, so that the slide 19 moves on the threaded rod 17 and moves it to a suitable position, and the other end of the workpiece is placed on the clamping plate 25, and then the moving block 9 is pressed down by the electric push rod 27 to plug the plug 26 on the rotating drum 21 into the slot 23, and the rotating drum 21 and the fixed drum 21 are fixed. The position of the second clamping plate 25 enables it to rotate on the transfer rail 13 of the moving block 9 and the slide 19, and the two clamping plates 25 clamp the other end of the workpiece through the elastic action of the spring 24, and increase the friction between the workpiece and the clamping plates through the rubber pad 16 and the rubber pad 27 to prevent the workpiece from falling. The rotating drum 13 and the rotating drum 21 form a rotating structure with the fixed box 12, the moving block 9 and the slide 19 through the clamping block 12, the clamping block 22 and the transfer rail 13, and then the driving motor 15 in the shell 14 is started to drive the rotating drum 13 to rotate. When the rotating drum 13 rotates, the rotating drum 21 connected to the rotating drum 13 through the workpiece is driven to rotate, so that the workpiece can be rotated according to the need to change the processing surface of the workpiece during processing, avoiding the need to disassemble the workpiece and flip the processing surface of the workpiece when the processing surface needs to be adjusted.
