Description

Technical Field

[0001] This utility model relates to the field of valve assembly technology, specifically a positioning fixture for assembling chemical valves. Background Technology

[0002] Valves are devices used in fluid systems to control the direction, pressure, and flow rate of fluids. They enable the flow or cessation of media (liquids, gases, powders) within piping and equipment and control their flow rate. The final step in valve manufacturing is assembling the valve body and valve cover. Existing technology involves manual assembly of the valve body and valve cover, but the valve body is often connected to flanges at both ends, which makes it unstable and difficult to provide stable support. This leads to inconvenience in assembling the valve cover and valve body, thus affecting the valve manufacturing efficiency. To address these issues, we propose a positioning fixture for chemical valve assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a positioning fixture for assembling chemical valves to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for assembling chemical valves, comprising a horizontal plate, two L-shaped plates above the horizontal plate, an arc-shaped block fixedly connected to the bottom inner wall of the L-shaped plate, two L-shaped blocks above the horizontal plate, two cylinders fixedly connected to the inner wall of the two L-shaped blocks on opposite sides, two round rods fixedly connected to the opposite sides of the two L-shaped plates, the cylinders slidably sleeved on the outer side of the corresponding round rods, a first spring fixedly connected between the cylinders and the corresponding L-shaped plates, the first spring movably sleeved on the outer side of the corresponding round rods, two rectangular holes opened at the top of the horizontal plate, a connecting rod rotatably connected to the bottom of the L-shaped blocks, the bottom end of the connecting rod passing through the corresponding rectangular holes and rotatably connected to a rectangular rod.

[0005] More preferably, a crossbar is fixedly connected to the bottom end of the rectangular rod, and a motor is fixedly connected to the bottom of the crossbar.

[0006] More preferably, a screw is fixedly connected to the end of the output shaft of the motor, the horizontal plate is threaded onto the outside of the screw, and two vertical rods are fixedly connected to the bottom of the horizontal plate.

[0007] More preferably, the horizontal seat is slidably sleeved on the outside of the two vertical rods, two support plates are fixedly connected to the top of the horizontal plate, and two positioning rods are fixedly connected to the sides of the two L-shaped blocks that are far apart from each other.

[0008] More preferably, a circular block is fixedly connected to the end of the positioning rod, and the same second spring is fixedly connected between the circular block and the corresponding support plate, with the second spring movably sleeved on the outside of the corresponding positioning rod.

[0009] More preferably, a support block is fixedly connected to the bottom inner wall of the L-shaped block, a circular plate is fixedly connected to the top of the support block, and a slide rail is fixedly connected to the top of the horizontal plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The motor of this utility model drives the horizontal seat to move upward through the rotation of the screw, which in turn squeezes the connecting rod. The connecting rod squeezes the L-shaped block, and the L-shaped block drives the circular plate to move through the L-shaped plate. The circular plate contacts the flange on the valve body. As the L-shaped block moves, the valve body restricts the movement of the L-shaped plate. The L-shaped block continues to move and compresses the first spring. The first spring generates a reaction force that allows the circular plate to fix the valve body. At this time, the valve cover can be placed on top of the valve body for assembly. This can stably support and effectively fix the valve body, making the assembly of the valve cover and valve body convenient and not affecting the valve processing efficiency.

The cylinders 5 are slidably sleeved on the outer side of the corresponding round rods 6, and a first spring 7 is fixedly connected between the cylinders 5 and the corresponding L-shaped plates 2. The first spring 7 is movably sleeved on the outer side of the corresponding round rods 6. Two rectangular holes 8 are opened at the top of the horizontal plate 1, and a connecting rod 9 is rotatably connected to the bottom of the L-shaped blocks 4. The bottom end of the valve body passes through the corresponding rectangular hole 8 and is rotatably connected to a rectangular rod 10. The motor 12 rotates through the screw 13 to drive the horizontal seat 11 to move upward and press the connecting rod 9. The connecting rod 9 presses the L-shaped block 4. The L-shaped block 4 moves the circular plate 20 through the L-shaped plate 2. The circular plate 20 contacts the flange on the valve body. As the L-shaped block 4 moves, the valve body restricts the movement of the L-shaped plate 2. The L-shaped block 4 continues to move and compresses the first spring 7. The first spring 7 generates a reaction force so that the circular plate 20 can fix the valve body. At this time, the valve cover can be placed on the top of the valve body for assembly. The valve body can be stably supported and effectively fixed, making the assembly of the valve cover and the valve body convenient and not affecting the processing efficiency of the valve.

[0020] In this embodiment, specifically: a horizontal seat 11 is fixedly connected to the bottom end of the rectangular rod 10, and a motor 12 is fixedly connected to the bottom of the horizontal plate 1;

[0021] In this embodiment, specifically: a screw 13 is fixedly connected to the end of the output shaft of the motor 12, a cross seat 11 is threaded onto the outside of the screw 13, and two vertical rods 14 are fixedly connected to the bottom of the cross plate 1;

[0022] In this embodiment, specifically: the horizontal seat 11 is slidably sleeved on the outside of the two vertical rods 14, the top of the horizontal plate 1 is fixedly connected to two support plates 15, and the two L-shaped blocks 4 are fixedly connected to two positioning rods 16 on the side away from each other. The positioning rods 16 are used to achieve the positioning effect.

[0023] In this embodiment, specifically: a circular block 17 is fixedly connected to the end of the positioning rod 16, and the same second spring 18 is fixedly connected between the circular block 17 and the corresponding support plate 15. The second spring 18 is movably sleeved on the outside of the corresponding positioning rod 16.

[0024] In this embodiment, specifically: a support block 19 is fixedly connected to the bottom inner wall of the L-shaped block 4, a circular plate 20 is fixedly connected to the top of the support block 19, and a slide rail 21 is fixedly connected to the top of the horizontal plate 1.

[0025] In this embodiment, specifically: two sliders 22 are slidably connected to the outer side of the slide rail 21, the top of the sliders 22 is fixedly connected to the bottom of the corresponding L-shaped block 4, a base plate 23 is provided below the horizontal plate 1, and four support legs 24 are fixedly connected between the top of the base plate 23 and the bottom of the horizontal plate 1.

[0026] In operation, this utility model is used as follows: The valve body is placed on top of the two arc-shaped blocks 3. Then, the motor 12 is started. The motor 12 drives the screw 13 to rotate, which in turn moves the horizontal seat 11 upwards. The horizontal seat 11 then moves the two rectangular rods 10 upwards. During this movement, the rectangular rods 10 press against the connecting rod 9. Under this pressure, the connecting rod 9 moves and rotates, pressing against the L-shaped block 4. Under this pressure, the L-shaped block 4 moves the corresponding two positioning rods 16, which in turn move the corresponding circular block 17. The circular block 17 compresses the second spring 18, causing the L-shaped block 4 to move the corresponding L-shaped plate 2. L-shaped plate 2 drives slider 22 to slide on the outside of slide rail 21. L-shaped plate 2 drives corresponding circular plate 20 to move. Circular plate 20 contacts flange on valve body. As L-shaped block 4 moves, valve body restricts the movement of L-shaped plate 2. L-shaped block 4 continues to move and compresses first spring 7. At this time, under the action of the elastic force of first spring 7, a reaction force is generated. The reaction force enables circular plate 20 to fix valve body. At this time, valve cover can be placed on top of valve body for assembly. Thus, a positioning fixture for chemical valve assembly is formed, which can stably support and effectively fix valve body, making valve cover and valve body assembly convenient and not affecting valve processing efficiency.
