[0024] Embodiment 1

[0025] See also Figure 1-Figure 3 A valve assembly fixture comprises a workbench 1, wherein support plates 2 are fixedly connected to the left and right sides of the upper surface of the workbench 1, a first cylinder 3 is fixedly installed on a side of the support plate 2 away from the center of the workbench 1, a frame plate 4 is fixedly connected to the output end of the first cylinder 3, a motor 5 is fixedly installed on the upper surface of the frame plate 4, a bidirectional threaded rod 6 is rotatably arranged between the upper and lower inner walls of the frame plate 4, two movable plates 7 are movably connected to the outer surface of the bidirectional threaded rod 6, a slide plate 8 is fixedly connected to the left surfaces of the two movable plates 7, a slide groove 9 is provided on the left inner wall of the frame plate 4, an arc plate 10 is fixedly connected to the right surfaces of the two movable plates 7, a clamping plate 11 is movably connected to the side of the arc plate 10 close to the center of the workbench 1, a first spring 12 is fixedly connected between the outer surface of the clamping plate 11 and the inner surface of the arc plate 10, two second cylinders 13 are fixedly installed on the lower surface of the workbench 1, and a placement plate 14 is movably installed on the output ends of the two second cylinders 13.

[0026] Specifically, through the coordination among structures such as the workbench 1, the support plate 2, the first cylinder 3, the frame plate 4, the motor 5, the bidirectional threaded rod 6, the movable plate 7, the slide plate 8, the slide groove 9, the arc plate 10, the clamping plate 11, the first spring 12, the second cylinder 13, and the placement plate 14, the four clamping plates 11 can be adjusted in distance up, down, left, and right so that the clamping plates 11 can adapt to valves of different sizes and stably clamp them. The elastic force buffer of the first spring 12 can reduce the clamping wear of the clamping plate 11 on the outer surface of the valve.

[0027] In this embodiment: the output end of the motor 5 is fixedly connected to the upper surface of the bidirectional threaded rod 6, and the two movable plates 7 are located at the upper and lower sides of the bidirectional threaded rod 6 and are both provided with thread grooves corresponding to the bidirectional threaded rod 6.

[0028] Specifically, the two movable plates 7 cooperate with the forward and reverse rotation of the bidirectional threaded rod 6 through the thread grooves, so that the two movable plates 7 move toward and away from each other.

[0029] In this embodiment, the slide plate 8 and the slide groove 9 are slidably arranged correspondingly, and the clamping plates 11 on both sides of the workbench 1 are correspondingly arranged through the arc plate 10.

[0030] Specifically, when the movable plate 7 moves by the forward and reverse rotation of the threaded groove in cooperation with the bidirectional threaded rod 6 , the movable plate 7 is moved horizontally by the sliding plate 8 in cooperation with the sliding groove 9 .

[0031] Working principle: When it is necessary to assemble the valve, the motor 5 on the frame plates 4 on both sides of the workbench 1 is turned on to drive the bidirectional threaded rod 6 to rotate forward. At the same time, the bidirectional threaded rod 6 cooperates with the thread groove on the movable plate 7 to move the upper and lower movable plates 7 closer to each other, and the distance between the arc plate 10 and the clamping plate 11 driven by the two movable plates 7 is reduced. At the same time, the movable plate 7 moves horizontally on the bidirectional threaded rod 6 through the slide plate 8 and the slide groove 9. After the movable plates 7 on both sides together with the arc plates 10 and the clamping plates 11 on the surface are adapted to the current batch of valves, the valve can be placed on the placement plate 14, and then the two second cylinders 13 are turned on to push the placement plate 14 to move upward, and the valve is moved. After moving to a position corresponding to the central angle of the clamping plates 11 on both sides, the first cylinder 3 on the support plates 2 on both sides is opened to push the two frame plates 4 closer to each other, so that the clamping plates 11 fit the valve surface. Through the pushing force on both sides, the clamping plates 11 are close to the valve and then cooperate with the arc plate 10 to compress the first spring 12 to reduce the initial contact friction. The valve is fixed and clamped by the movable plate 7 in cooperation with the arc plate 10 and the clamping plates 11, and subsequent assembly work can be carried out. For the spacing of the clamping plates 11, the bidirectional threaded rod 6 can be reversed by the motor 5, thereby driving the two movable plates 7 to move away from each other, thereby expanding the spacing between the arc plate 10 and the clamping plates 11 on the movable plate 7.

[0032] Embodiment 2

[0033] See also Figure 1-Figure 2 , Figure 4-Figure 5 Based on the first embodiment, the present invention provides a technical solution:

[0034] In this embodiment: a plurality of slots 15 are provided on the upper surface of the placement plate 14, a pulley 16 is rotatably provided between the left and right inner walls of the slot 15, two sleeves 17 are fixedly connected to the lower surface of the placement plate 14, and circular plates 18 are movably connected to the inner surfaces of the two sleeves 17, and a second spring 19 is fixedly connected between the upper surface of the circular plate 18 and the upper inner wall of the sleeve 17.

[0035] Specifically, through the coordination among the structures such as the slot 15, the pulley 16, the sleeve 17, the circular plate 18, and the second spring 19, the valve can be placed on the placement plate 14 and can be conveniently moved to adjust the position or taken out. It can also provide a buffer when the valve is placed on the placement plate 14, so that the valve can be stably placed on the placement plate 14.

[0036] In this embodiment, the lower surface of the circular plate 18 is fixedly connected to the output end of the second cylinder 13 , and the second spring 19 is wound around the inner surface of the sleeve 17 .

[0037] Specifically, the gravity of the valve placed on the placement plate 14 drives the placement plate 14 and the sleeve 17 to cooperate with the circular plate 18 on the second cylinder 13 to squeeze the second spring 19, thereby buffering the valve when it is placed and reducing damage.

[0038] Working principle: When assembling the valve, the valve needs to be placed on the placement plate 14. When the valve contacts the placement plate 14, the placement plate 14 is driven down by the gravity of the valve. At the same time, the placement plate 14 drives the sleeve 17 at the bottom to cooperate with the circular plate 18 on the second cylinder 13 to squeeze the second spring 19, thereby buffering the gravity of the valve. After the valve is placed on the placement plate 14, the valve can be pushed to move back and forth on the placement plate 14. The bottom of the valve fits the pulley 16 on the placement plate 14, and the pulley 16 is driven to rotate in the slot 15 through the moving force, so that the valve is quickly centered and assembled by quick limit work.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
