Technical Field
[0001] This utility model belongs to the field of ball valve processing technology, specifically a ball valve processing clamping device. Background Technology
[0002] A ball valve is a type of valve in which the valve stem drives the valve to rotate around the ball valve axis. It can also be used for fluid regulation and control. In pipelines, ball valves are mainly used for cutting off, distributing and changing the flow direction of the medium. It can be tightly closed with only a 90-degree rotation and a very small torque. Its production process requires the use of a special clamping device.
[0003] Existing clamping devices for ball valve machining often rely on the surface platform of the ball to clamp and fix it during the process of clamping the ball. After clamping, the contact area between the clamping component and the ball is small, and the force range of the component on the ball is small, which can easily cause the ball to deflect during the machining process and affect the machining accuracy.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a ball valve processing clamping device according to an embodiment of the present invention includes a housing 1. A semi-circular clamping plate 11 is rotatably connected to the side wall of the housing 1, and the two semi-circular clamping plates 11 are correspondingly arranged. A top box 12 is fixedly connected to the side wall of the semi-circular clamping plate 11. A top block 13 is slidably connected inside the housing 1, and the top block 13 is positioned corresponding to the top box 12. A transmission roller 15 is rotatably connected inside the housing 1, and a top plate 14 and a transmission gear 16 are fixedly connected to the side wall of the transmission roller 15. A power gear 17 meshes with the bottom of the transmission gear 16. A power roller 18 is fixedly connected to the side wall of the power gear 17, and a torque motor 19 is provided at the end of the power roller 18. During operation, the torque motor 19 is fixedly connected to the side wall of the housing 1, and the power roller 18 is rotatably connected to the housing 1. The operator can drive the torque motor 19. The top block 13 presses against the top box 12, causing multiple semi-circular clamping pieces 11 to contact the side wall of the ball valve to be processed, thus completing the clamping. During the process, whenever the torque motor 19 is driven, since the power roller 18 is fixedly connected to the output end of the torque motor 19, and the power gear 17 is meshed with the transmission gear 16, the two top plates 14 will rotate along with the transmission roller 15. At this time, the two top plates 14 will contact the corresponding top blocks 13 respectively, causing the top blocks 13 to press against the top box 12. Through the above structure, the power gear 17 and the transmission gear 16 are set to enhance the torque of the torque motor 19, and the top plates 14 and top blocks 13 are set to press against the top box 12, causing the semi-circular clamping pieces 11 to contact the side wall of the ball valve. This increases the force range of the clamping device on the ball valve, which is beneficial to improving the stability of the clamped ball valve.
[0026] like Figure 1 and Figure 2As shown, a fixed platform 2 is fixedly connected to the side wall of the chassis 1; a base plate 21 is provided at the bottom of the fixed platform 2; a moving motor 22 is fixedly connected to the side wall of the base plate 21, and a bidirectional lead screw 23 is fixedly connected to the output end of the moving motor 22; the bidirectional lead screw 23 is threadedly connected to the fixed platform 2; a limit block 24 is fixedly connected to the side wall of the fixed platform 2, and the two limit blocks 24 are correspondingly arranged; a limit groove 25 is opened on the top of the base plate 21, and the position and size of the limit groove 25 correspond to the limit block 24; during operation, the operator can adjust the relative distance between the two fixed platforms 2 by driving the moving motor 22, thereby adjusting the relative distance between the two chassis 1, thus making it easier to clamp and fix the ball valve. During the process, whenever the fixed platform 2 is fixedly connected to the side wall of the chassis 1, the operator can adjust the relative distance between the two fixed platforms 2, thereby adjusting the relative distance between the two chassis 1, thus making it easier to clamp and fix the ball valve. When the movable motor 22, which is attached to the side wall of the base plate 21, is driven, the bidirectional lead screw 23, which is fixed to the output end of the movable motor 22, rotates. Since the bidirectional lead screw 23 is threadedly connected to the two fixed platforms 2, and the limiting block 24, which is fixed to the side wall of the fixed platform 2, is in contact with and constrained by the limiting groove 25 opened on the top of the base plate 21, the two fixed platforms 2 will move along with the output of the movable motor 22. Through the above structure, the movable motor 22 and the bidirectional lead screw 23 are set to adjust the relative distance between the two housings 1, which enhances the flexibility and applicability of the device, provides convenience for the ball valve clamping operation of the workers, reduces the difficulty of clamping the ball valve, and helps to improve the ball valve fixing speed and increase work efficiency.
[0027] like Figure 3 As shown, a fixing plate 3 is fixedly connected to the side wall of the semicircular clamping plate 11, and the fixing plate 3 is sized to correspond to the semicircular clamping plate 11. A clamping protrusion 31 is fixedly connected to the side wall of the fixing plate 3, and multiple clamping protrusions 31 are arranged correspondingly. The fixing plate 3 and the clamping protrusions 31 are made of rubber. During operation, the multiple clamping protrusions 31 are respectively arranged to correspond to the surface contour of the ball valve. Whenever the semicircular clamping plate 11 moves towards the ball valve under the pressure of the top block 13, the multiple clamping protrusions 31 fixed to the side wall of the fixing plate 3 and made of rubber will replace the semicircular clamping plate 11 and contact the side wall of the ball valve. Through the above structure, the fixing plate 3 and the clamping protrusions 31 replace the semicircular clamping plate 11 and contact the side wall of the ball valve. The fixing plate 3 and the clamping protrusions 31 are made of rubber, which takes advantage of the strong plasticity of rubber, which helps to improve the stability of the ball valve, avoid the ball valve from being displaced during processing, and enhance the processing accuracy.
[0028] like Figure 5As shown, a stop protrusion 4 is fixedly attached to the inner side wall of the chassis 1, and the two stop protrusions 4 are respectively set to the position and size of the top plate 14; the stop protrusions 4 are made of rubber; during operation, whenever the top plate 14 rotates to the position of the stop protrusion 4 under the action of the torque motor 19, the stop protrusion 4 made of rubber can stop the rotation of the top plate 14 by contact; through the above structure, the stop protrusion 4 is set to block the top plate 14, thereby avoiding its collision with adjacent components. The stop protrusion 4 is made of rubber to take advantage of the flexibility of rubber, thereby reducing the noise of the device.
[0029] like Figure 4 As shown, a limiting disc 5 is fixedly connected to the side wall of the top plate 14, and the two limiting discs 5 are arranged correspondingly. During operation, the limiting disc 5 fixed to the side wall of the top plate 14 contacts the side wall of the top block 13. The limiting disc 5 can maintain the contact relationship between the top block 13 and the top plate 14 through contact. Through the above structure, the limiting disc 5 limits the top block 13, thereby maintaining the contact relationship between the top block 13 and the top plate 14, enhancing the stability and risk resistance of the device, and helping to extend the service life of the device.
[0030] like Figure 4 and Figure 5 As shown, a torsion spring is provided between the housing 1 and the semi-circular clamping plate 11. During operation, after the ball valve is processed, the operator drives the torque motor 19 to release the pressure between the top plate 14 and the top block 13. At this time, since a torsion spring is provided between the housing 1 and the semi-circular clamping plate 11, the torsion spring can release the elastic force to reset the corresponding semi-circular clamping plate 11, thereby causing the ball valve to fall off. Through the above structure, the torsion spring is provided between the housing 1 and the semi-circular clamping plate 11 to allow the semi-circular clamping plate 11 to naturally reset after clamping, which improves the practicality and convenience of the device and helps to avoid the semi-circular clamping plate 11 from hindering the ball valve from falling off.
[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the chassis 1, semi-circular clamping plate 11, top box 12, top plate 14, top block 13, transmission gear 16, and power gear 17 are made of stainless steel. During operation, the use of stainless steel in the chassis 1, semi-circular clamping plate 11, top box 12, top plate 14, top block 13, transmission gear 16, and power gear 17 allows them to leverage the advantages of stainless steel, such as strong corrosion resistance, high structural strength, and smooth surface. By employing stainless steel in the chassis 1, semi-circular clamping plate 11, top box 12, top plate 14, top block 13, transmission gear 16, and power gear 17, the structural strength of the device is enhanced, the friction coefficient between components is reduced, which helps prevent component jamming, reduces the difficulty of device maintenance, and extends the service life of the device.
[0032] During operation, the torque motor 19 is fixed to the side wall of the housing 1, and the power roller 18 is rotatably connected to the housing 1. The operator can drive the torque motor 19 to cause the top block 13 to press against the top box 12, thereby causing multiple semi-circular clamping plates 11 to contact the side wall of the ball valve to be processed, thus clamping it. During the process, whenever the torque motor 19 is driven, because the power roller 18 is fixedly connected to the output end of the torque motor 19, and the power gear 17 is meshed with the transmission gear 16, the two top plates 14 will rotate along with the transmission roller 15. At this time, the two top plates 14 will respectively interact with the corresponding... When the top block 13 comes into contact, it presses against the top box 12. The operator can adjust the relative distance between the two fixed platforms 2 by driving the moving motor 22, thereby adjusting the relative distance between the two housings 1, thus making it easier to clamp and fix the ball valve. During the process, whenever the moving motor 22 fixed to the side wall of the base plate 21 is driven, the bidirectional lead screw 23 fixed to the output end of the moving motor 22 rotates. Since the bidirectional lead screw 23 is threadedly connected to the two fixed platforms 2, and the limiting block 24 fixed to the side wall of the fixed platform 2 is in contact with the limiting groove 25 opened on the top of the base plate 21, Constraints are applied, and with the output of the moving motor 22, the two fixed platforms 2 will move. Multiple clamping protrusions 31 are respectively set to correspond to the surface contour of the ball valve. Whenever the semi-circular clamping piece 11 moves towards the ball valve under the pressure of the top block 13, multiple clamping protrusions 31, which are fixed to the side wall of the fixed piece 3 and are made of rubber, will replace the semi-circular clamping piece 11 and contact the side wall of the ball valve. Whenever the top plate 14 rotates to the position of the stop protrusion 4 under the action of the torque motor 19, the stop protrusion 4, made of rubber, can stop the rotation of the top plate 14 by contact. The limiting plate 5, which is fixed to the side wall of the top plate 14, contacts the top plate 14. On the side wall of block 13, the limiting plate 5 can maintain the contact relationship between the top block 13 and the top plate 14 by contact. After the ball valve is processed, the operator drives the torque motor 19 to release the pressure between the top plate 14 and the top block 13. At this time, since a torsion spring is provided between the housing 1 and the semi-circular clamping plate 11, the torsion spring can release the elastic force to reset the corresponding semi-circular clamping plate 11, thereby causing the ball valve to fall off. The housing 1, semi-circular clamping plate 11, top box 12, top plate 14, top block 13, transmission gear 16 and power gear 17 made of stainless steel can give full play to the advantages of stainless steel's strong corrosion resistance, high structural strength and smooth surface.
