[0002] Valves are mechanical devices that control the flow rate, direction, pressure, and temperature of flowing fluid media. Valves are basic components in pipeline systems. Technically, valve fittings, like pumps, are often discussed as a separate category. Valves can be operated manually or by handwheel, handle, or pedal, and can also be controlled to change the pressure, temperature, and flow rate of the fluid medium. Valve clamping fixtures are specialized clamping tools used to fix and support valve components during valve manufacturing and repair, ensuring the accuracy and quality of machining or assembly.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although existing technologies can clamp valves, their stability is poor during clamping and rotation, which may lead to valve detachment and reduce safety.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a clamping fixture for valve processing, including a clamping component 2, of which two clamping components 2 are provided and distributed symmetrically, the clamping components 2 are used to clamp the valve; a stabilizing component 3 is provided on one side of the clamping components 2, the stabilizing component 3 is used to stabilize the inner cavity of the valve; and a limiting component 1 is provided on one side of the clamping components 2 and the stabilizing components 3, the limiting component 1 is used to limit the clamping components 2 and the stabilizing components 3;

[0026] When the valve needs to be clamped, the limiting component 1 is first clamped on the lathe. Then, two clamping components 2 are fixedly connected to the two sides of the center position on one side surface of the limiting component 1, so that the limiting component 1 can limit the two clamping components 2, thereby clamping and fixing the valve. Since a stabilizing component 3 is fixedly connected to the center position on one side surface of the limiting component 1, the limiting component 1 can limit the stabilizing component 3, thereby allowing the stabilizing component 3 to be inserted into the valve cavity, so that the stabilizing component 3 can clamp and fix the valve, thereby improving the stability of the valve and improving safety. Then, through the limiting component 1, the stabilizing component 3 and the clamping components 2 can be driven to rotate, thereby driving the valve to rotate, so as to facilitate the operation of the operator.

[0027] See Figure 1 , Figure 2 The limiting component 1 includes a turntable 11. A clamping post 12 is provided at the center of one side surface of the turntable 11. Movable grooves 13 are provided on both sides at the center of the other side surface of the turntable 11. The inner cavity of the movable groove 13 is connected to the clamping component 2. Irregular sliding grooves 18 are provided at the center of the two side walls of the inner cavity of the movable groove 13. Fixed grooves 14 are provided at the center of the other side surface of the turntable 11. A mounting plate is provided at the center of the inner cavity of the fixed groove 14. An internal threaded hole 15 is provided at the center of one side surface of the mounting plate. The inner cavity of the internal threaded hole 15 is connected to the stabilizing component 3. Limiting brackets 16 are provided on the top surface of the two fixed grooves 14. Limiting grooves 17 are provided at the center of the top surface of the two limiting brackets 16. The inner cavity of the limiting grooves 17 is connected to the stabilizing component 3.

[0028] The turntable 11 in the limiting component 1 can be placed in a preset position and also provides an installation base for the clamping column 12, thus enabling the turntable 11 to support the clamping column 12 and allowing the lathe to clamp and fix the clamping column 12, so that the lathe can drive the turntable 11 to rotate. Since there are moving grooves 13 on both sides of the center position of the other side surface of the turntable 11, and irregular sliding grooves 18 are formed on the center position of both sides of the inner wall of the moving grooves 13, and the inner cavities of the moving grooves 13 and the irregular sliding grooves 18 are connected to the clamping component 2, the moving grooves 13 and the irregular sliding grooves 18 can limit the clamping component 2, allowing the clamping component 2 to move within the inner cavities of the moving grooves 13 and the irregular sliding grooves 18, thereby improving the stability of the clamping component 2 and enabling it to handle valves of different sizes. The door is clamped. Since a fixing groove 14 is provided in the center of the other side surface of the turntable 11, and a mounting plate is provided in the center of the cavity of the fixing groove 14, and an internal threaded hole 15 is provided in the center of one side surface of the mounting plate, the cavity of the internal threaded hole 15 is connected to the stabilizing component 3, so that the mounting plate can divide the fixing groove 14 into two parts, and the stabilizing component 3 can rotate in the cavity of the internal threaded hole 15, so as to guide the stabilizing component 3. Since the top surface of the two fixing grooves 14 is fixedly connected to the limit frame 16, and the top surface of the two limit frames 16 is provided with a limit groove 17 in the center, and the cavity of the limit groove 17 is connected to the stabilizing component 3, the limit groove 17 can limit the stabilizing component 3, and thus guide the stabilizing component 3.

[0029] See Figure 1 , Figure 3The clamping assembly 2 includes a screw 21, which is disposed in the inner cavity of the moving groove 13. A bearing 22 is provided at one end of the screw 21. A moving plate 23 is sleeved on the outside of the screw 21. A connecting plate 24 is provided on one side of the moving plate 23. A pressing plate 25 is provided on one side of the connecting plate 24. A C-shaped plate 26 is provided on one side of the pressing plate 25. An anti-slip pad 27 is provided in the inner cavity of the C-shaped plate 26. A shaped slider 28 is provided on both the top and bottom surfaces of the moving plate 23. The shaped slider 28 is connected to the inner cavity of the shaped groove 18.

[0030] The screw 21 in the clamping assembly 2 can be rotatably connected to the inner cavity of the moving slot 13 and also provide a mounting base for the bearing 22. This allows the screw 21 to be inserted into the inner cavity of the bearing 22 and rotate within it. Since a moving plate 23 is sleeved on the outside of the screw 21, and a connecting plate 24 is fixedly connected to one side of the moving plate 23, while a pressure plate 25 is fixedly connected to one side of the connecting plate 24, and a C-shaped plate 26 is fixedly connected to one side of the pressure plate 25, the rotation of the screw 21 drives the moving plate 23 to move. This, in turn, allows the moving plate 23 to move via the connecting plate 24, which in turn moves the pressure plate 25, thus enabling the pressure plate 25 to move the C-shaped plate 26. This allows the C-shaped plate 26 to clamp the valve, enabling it to clamp valves of different sizes. Since the inner cavity of the C-shaped plate 26 is fixedly connected with an anti-slip pad 27, the friction within the C-shaped plate 26 is increased, thereby improving the clamping stability and safety. Because the top and bottom surfaces of the moving plate 23 are both fixedly connected with irregularly shaped sliders 28, and these sliders 28 are connected to the inner cavity of the irregularly shaped groove 18, the moving plate 23 moves while simultaneously driving the irregularly shaped sliders 28 to move within the irregularly shaped groove 18. This allows the irregularly shaped groove 18 to guide the moving plate 23, further improving its stability.

[0031] See Figure 1 , Figure 4 The stabilizing component 3 includes a lead screw 31, which is disposed in an internal threaded hole 15. Two threaded sleeves 32 are sleeved on the lead screw 31. A fixing rod 33 is provided on one side of each of the two threaded sleeves 32. An arc-shaped plate 34 is provided on one side of each of the fixing rods 33. A rubber pad 35 is provided on the outer side of each of the two arc-shaped plates 34. The rubber pad 35 is used to increase the friction of the arc-shaped plates 34.

[0032] By using the lead screw 31 in the stabilizing component 3, it can be rotatably connected to the inner cavity of the internal threaded hole 15 and also provide an installation base for the two threaded sleeves 32. Since a fixing rod 33 is fixedly connected to one side of each of the two threaded sleeves 32, and an arc plate 34 is fixedly connected to one side of each of the two fixing rods 33, the lead screw 31 can adjust the position of the threaded sleeve 32, which in turn can adjust the position of the fixing rod 33, so that the fixing rod 33 can adjust the position of the arc plate 34. Then, through the arc plate 34, the valve can be limited and fixed, thereby limiting and fixing different valves to improve valve stability. Since rubber pads 35 are provided on the outer side of each of the two arc plates 34, the friction of the arc plates 34 can be increased, thereby improving the stability of the arc plates 34 and thus improving safety.

[0033] During operation, when the valve needs to be clamped, the limiting component 1 is first clamped on the lathe. Then, two clamping components 2 are fixedly connected to the two sides of the center position on one side surface of the limiting component 1, so that the limiting component 1 can limit the two clamping components 2, thereby clamping and fixing the valve. Since a stabilizing component 3 is fixedly connected to the center position on one side surface of the limiting component 1, the limiting component 1 can limit the stabilizing component 3, thereby allowing the stabilizing component 3 to be inserted into the valve cavity, so that the stabilizing component 3 can clamp and fix the valve, thereby improving the stability of the valve and improving safety. Then, through the limiting component 1, the stabilizing component 3 and the clamping components 2 can be driven to rotate, thereby driving the valve to rotate, so as to facilitate the operator's processing.

[0034] The turntable 11 in the limiting component 1 can be placed in a preset position and also provides an installation base for the clamping column 12, thus enabling the turntable 11 to support the clamping column 12 and allowing the lathe to clamp and fix the clamping column 12, so that the lathe can drive the turntable 11 to rotate. Since there are moving grooves 13 on both sides of the center position of the other side surface of the turntable 11, and irregular sliding grooves 18 are formed on the center position of both sides of the inner wall of the moving grooves 13, and the inner cavities of the moving grooves 13 and the irregular sliding grooves 18 are connected to the clamping component 2, the moving grooves 13 and the irregular sliding grooves 18 can limit the clamping component 2, allowing the clamping component 2 to move within the inner cavities of the moving grooves 13 and the irregular sliding grooves 18, thereby improving the stability of the clamping component 2 and enabling it to handle valves of different sizes. The door is clamped. Since a fixing groove 14 is provided in the center of the other side surface of the turntable 11, and a mounting plate is provided in the center of the cavity of the fixing groove 14, and an internal threaded hole 15 is provided in the center of one side surface of the mounting plate, the cavity of the internal threaded hole 15 is connected to the stabilizing component 3, so that the mounting plate can divide the fixing groove 14 into two parts, and the stabilizing component 3 can rotate in the cavity of the internal threaded hole 15, so as to guide the stabilizing component 3. Since the top surface of the two fixing grooves 14 is fixedly connected to the limit frame 16, and the top surface of the two limit frames 16 is provided with a limit groove 17 in the center, and the cavity of the limit groove 17 is connected to the stabilizing component 3, the limit groove 17 can limit the stabilizing component 3, and thus guide the stabilizing component 3.

[0035] The screw 21 in the clamping assembly 2 can be rotatably connected to the inner cavity of the moving slot 13 and also provide a mounting base for the bearing 22. This allows the screw 21 to be inserted into the inner cavity of the bearing 22 and rotate within it. Since a moving plate 23 is sleeved on the outside of the screw 21, and a connecting plate 24 is fixedly connected to one side of the moving plate 23, while a pressure plate 25 is fixedly connected to one side of the connecting plate 24, and a C-shaped plate 26 is fixedly connected to one side of the pressure plate 25, the rotation of the screw 21 drives the moving plate 23 to move. This, in turn, allows the moving plate 23 to move via the connecting plate 24, which in turn moves the pressure plate 25, thus enabling the pressure plate 25 to move the C-shaped plate 26. This allows the C-shaped plate 26 to clamp the valve, enabling it to clamp valves of different sizes. Since the inner cavity of the C-shaped plate 26 is fixedly connected with an anti-slip pad 27, the friction within the C-shaped plate 26 is increased, thereby improving the clamping stability and safety. Because the top and bottom surfaces of the moving plate 23 are both fixedly connected with irregularly shaped sliders 28, and these sliders 28 are connected to the inner cavity of the irregularly shaped groove 18, the moving plate 23 moves while simultaneously driving the irregularly shaped sliders 28 to move within the irregularly shaped groove 18. This allows the irregularly shaped groove 18 to guide the moving plate 23, further improving its stability.

[0036] By using the lead screw 31 in the stabilizing component 3, it can be rotatably connected to the inner cavity of the internal threaded hole 15 and also provide an installation base for the two threaded sleeves 32. Since a fixing rod 33 is fixedly connected to one side of each of the two threaded sleeves 32, and an arc plate 34 is fixedly connected to one side of each of the two fixing rods 33, the lead screw 31 can adjust the position of the threaded sleeve 32, which in turn can adjust the position of the fixing rod 33, so that the fixing rod 33 can adjust the position of the arc plate 34. Then, through the arc plate 34, the valve can be limited and fixed, thereby limiting and fixing different valves to improve valve stability. Since rubber pads 35 are provided on the outer side of each of the two arc plates 34, the friction of the arc plates 34 can be increased, thereby improving the stability of the arc plates 34 and thus improving safety.

[0037] In summary, this device can both clamp and limit the valve, thereby improving the stability of valve rotation and thus enhancing safety.
