[0023] It should be noted that the control method of the present application is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present application is mainly used to protect mechanical devices, so the present application will no longer explain the control method and circuit connection in detail.

[0024] See also Figure 1-4 The clamping mechanism includes a cylinder 501 fixed on the inner wall of the front side of the rectangular warehouse 1. The clamping mechanism is driven by a cylinder 501 to synchronously drive the clamping plates 3 on both sides for clamping. There is no need for too many power drive components, which reduces the manufacturing cost of the device and the subsequent maintenance and use cost, has better economic benefits and is more practical. A connecting plate 502 is fixed to the rear end of the output shaft of the cylinder 501. A slide groove 503 is provided on the top surface of the connecting plate 502. Two slide rods 504 are slidably connected in the slide groove 503. When it is necessary to speed up the valve component for processing, the valve component is placed between the four clamping plates 3, and then the cylinder 501 is retracted. The cylinder 501 drives the connecting plate 502 to move forward, and the connecting plate 502 drives the slide rod 504 to slide forward. The gear column 50 is rotatably connected between the inner walls on the left and right sides of the clamping warehouse 2. 5. A tooth plate 506 meshing with the gear column 505 is fixed at one end of the clamping plate 3 located inside the clamping bin 2. The top end of the slide bar 504 is fixed to the bottom tooth plate 506. The tooth plates 506 on the front and rear clamping plates 3 are respectively meshed with the upper and lower sides of the gear column 505. The tooth plates 506 on the upper and lower clamping plates 3 are respectively meshed with the rear and front sides of the gear column 505. A long hole 507 is provided on the bottom surface of the clamping bin 2 for the slide bar 504 to slide back and forth. The slide bar 504 drives the bottom tooth plate 506 to move forward, and the bottom tooth plate 506 drives the gear column 505 to rotate. The gear column 505 drives the tooth plate 506 on the front side thereof to move up, the tooth plate 506 on the rear side to move down, and the tooth plate 506 on the top to move backward, so that the four tooth plates 506 drive the four clamping plates 3 to move synchronously in the center to clamp the valve member.

[0025] Two guide rods 508 are fixed between the front and rear inner walls of the rectangular bin 1, which penetrate the connecting plate 502 front and back and are slidably connected thereto. Two guide holes 509 are provided on the front side of the connecting plate 502 for the guide rods 508 to penetrate and be slidably connected thereto. When the cylinder 501 drives the connecting plate 502 to move back and forth, the stability of the connecting plate 502 sliding back and forth can be effectively improved by cooperating with the guide holes 509 through the arranged guide rods 508. A rectangular hole 7 is provided on the top surface of the rectangular bin 1 for the two clamping bins 2 to slide left and right inside it. The bottom end of the clamping bin 2 penetrates the rectangular hole 7 and extends to the inside of the rectangular bin 1. The four clamping plates 3 on the same clamping bin 2 are distributed in a circle with equal angles with the central axis of the gear column 505 as the center. A clamping block is fixed on the side of the clamping plate 3 facing the central axis of the gear column 505.

[0026] The long hole 507 is used for allowing the slide rod 504 to move forward and backward inside it, and the slide groove 503 is used for allowing the slide rod 504 to move left and right inside it. It should be understood that when the two clamping bins 2 slide left and right for adjustment, the slide rod 504 will be driven to slide left and right inside the slide groove 503 but will not separate from the connecting plate 502, so that the two slide rods 504 can be controlled to move forward and backward through the cylinder 501.

[0027] See also Figure 2-4 In this embodiment, the adjustment mechanism includes a guide block 601 fixed on the back of the clamping bin 2, a guide groove 602 for sliding connection of the guide block 601 is provided on the inner wall of the rear side of the rectangular bin 1, a threaded block 603 is fixed on the front of the clamping bin 2, and a threaded rod 604 horizontally penetrating the two threaded blocks 603 and threadedly connected thereto is rotatably connected between the inner walls on the left and right sides of the rectangular bin 1, and two threaded grooves 605 are provided on the outer peripheral wall of the threaded rod 604, and the spiral directions of the two threaded grooves 605 are opposite. When the distance between the two clamping bins 2 needs to be adjusted after the valve components are clamped by the clamping bins 2 on both sides, the threaded rod 604 is rotated, and the threaded rod 604 drives the two threaded blocks 603 to move relative to or away from each other through the two threaded grooves 605 with opposite thread directions, thereby driving the two clamping bins 2 to cooperate with the guide block 601 and the guide groove 602 to slide left and right for adjustment.

[0028] The guide groove 602 is used for the guide block 601 to slide left and right inside it. The left end of the threaded rod 604 extends to the outside of the rectangular bin 1. A handle is fixed to the left end of the threaded rod 604. The handle is provided to facilitate the rotation of the threaded rod 604 to adjust the distance between the two clamping bins 2. A threaded hole is provided on the right side of the threaded block 603 for the threaded rod 604 to pass through and to match the threaded groove 605.

[0029] The working principle of the above embodiment is:

[0030] (1) When the valve component needs to be tightened for processing, the valve component is placed between the four clamping plates 3, and then the cylinder 501 is retracted. The cylinder 501 drives the connecting plate 502 to move forward, and the connecting plate 502 drives the sliding rod 504 to slide forward. The sliding rod 504 drives the bottom tooth plate 506 to move forward, and the bottom tooth plate 506 drives the gear column 505 to rotate. The gear column 505 drives the tooth plate 506 on the front side to move upward, the tooth plate 506 on the rear side to move downward, and the tooth plate 506 on the top to move backward, so that the four tooth plates 506 drive the four clamping plates 3 to move synchronously in the center to clamp the valve component.

[0031] (2) When the distance between the two clamping bins 2 needs to be adjusted after the two clamping bins 2 clamp the valve components, the threaded rod 604 is rotated. The threaded rod 604 drives the two threaded blocks 603 to move relative to or away from each other through two threaded grooves 605 with opposite thread directions, thereby driving the two clamping bins 2 to slide left and right in coordination with the guide blocks 601 and the guide grooves 602 for adjustment.
