Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a valve clamping device for valve processing. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. During the processing of valves, they need to be clamped and fixed by clamping devices. Valve clamping devices used in valve processing are indispensable tools in valve manufacturing. They are used to fix the valve body, ensure stability and accuracy during processing, and ensure the processing accuracy of the valve in subsequent grinding, polishing, or assembly.

[0003] CN221911420U discloses an adjustable clamping device for valve processing, including a base. By placing the valve on a placement block, the output shaft of the second drive motor in the clamping assembly drives the connected bidirectional threaded rod to rotate. The pulley sleeved at one end of the bidirectional threaded rod is connected to another set of pulleys via a belt, thereby driving the other set of bidirectional threaded rods to rotate synchronously. The two sets of bidirectional threaded rods simultaneously drive the two sets of sliding blocks threaded to their outer walls to slide, so that the four sets of sliding blocks drive the four sets of clamping blocks at the top to move relative to each other, so that the four sets of clamping blocks can quickly clamp and fix the valve. The output shaft of the first drive motor in the drive assembly drives the active bevel gear and the driven bevel gear to mesh, so that the rotating rod drives the rotating disk to rotate under the cooperation of the rotating disk bearing, which can rotate the valve clamped and fixed on the surface of the support table, realize the adjustment of the valve angle, and facilitate the processing and grinding of the other end face of the valve.

[0004] While the existing technology CN221911420U has many advantages in use, it still has the following problems: its clamping tightness for valves is not perfect. When clamping valves of different sizes, the fit between the clamping component and the valve is poor, which will affect the clamping stability of the valve. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a valve clamping device for valve processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a valve clamping device for valve processing, including a processing table, a slider, a drive motor and a connecting plate. The processing table has a sliding groove inside, and sliders are slidably installed on both sides of the inner wall of the sliding groove. A damping bearing is embedded in the slider, and a rotating shaft is interference-fitted inside the damping bearing. A support column is welded to the outer wall of the upper end of the rotating shaft. The outer wall of the support column has a circular array of fitting grooves, and fitting blocks are set inside the fitting grooves. Drive motors are set on both sides of the lower outer wall of the processing table, and rectangular array of support legs are installed on the lower outer wall of the processing table.

[0007] By adopting the above technical solution, the slide ensures the stability of the horizontal movement of the slider and allows for adjustment of the spacing between the clamping components. The clamping components can clamp and fix the valve. The interference fit of the damping bearing and the rotating shaft ensures the stable rotation of the support column. After the rotating shaft is adjusted by rotation, it can adjust different clamping components. It ensures that the inner diameter of the clamping component is compatible with the size of the valve to be clamped, providing a stable clamping environment for the valve. Furthermore, the assembly of the fitting groove and the fitting block ensures the stability of the clamping component's position during use.

[0008] Specifically, a connecting plate is installed on the lower outer wall of the rotating shaft, and the connecting plate is located at the lower end of the slider.

[0009] By adopting the above technical solution, the drive motor can drive the rotation of the support column through the connecting plate, thereby adjusting the position of the clamping component and ensuring that the inner diameter of the clamping component is compatible with the size of the valve. This design simplifies the transmission mechanism, improves transmission efficiency, and ensures the precise movement of the clamping component.

[0010] Specifically, a clamping member is welded to the outer wall of one end of the interlocking block, and a clamping groove is formed inside the clamping member, and the inner diameter of the clamping groove is inconsistent.

[0011] By adopting the above technical solution, the clamping grooves inside the clamping components have inconsistent inner diameters, which can accommodate valves of different sizes and shapes. This design increases the adaptability of the device, allowing the same device to clamp multiple types of valves, while ensuring the tightness of the clamping between the clamping components and the valves, and reducing production costs.

[0012] Specifically, a bolt is provided on one side of the outer wall of the interlocking block, and the interlocking block is connected to the inner wall of the interlocking groove through the bolt.

[0013] By adopting the above technical solution, the detachable design of the bolt facilitates the replacement and maintenance of the clamping parts. At the same time, the bolt connection also ensures the stability of the interlocking block in the interlocking groove and prevents the clamping parts from loosening during use.

[0014] Specifically, push rod bodies are provided on both sides of the upper outer wall of the processing table. One end of the outer wall of the push rod body is connected to the slider. A fastener is provided on one side of the outer wall of the push rod body, and the push rod body is connected to the upper outer wall of the processing table through the fastener.

[0015] By adopting the above technical solution, the fasteners enable the push rod body to be more securely connected to the processing table, preventing the push rod body from sliding or shifting during the processing. At the same time, the design of the push rod body also facilitates the movement and adjustment of the slider, and can adjust the spacing between the clamping parts, thus improving the ease of operation of the device.

[0016] Specifically, support frames are installed on both sides of the outer wall of the drive motor. A base plate is welded to the upper outer wall of the support frame. Screws arranged in a rectangular array are provided inside the base plate, and the base plate is connected to the lower outer wall of the processing table through the screws.

[0017] By adopting the above technical solution, the design of the support frame and base plate provides stable support for the drive motor, ensuring its smooth operation. The screw connection method allows the base plate to be easily installed under the processing table, and also facilitates the disassembly and maintenance of the drive motor.

[0018] Specifically, a drive plate is provided on the upper outer wall of the drive motor, the drive plate is located at the lower end of the connecting plate, and magnets are embedded in the outer walls of the drive plate and the connecting plate on opposite sides.

[0019] By adopting the above technical solution, the magnet at the upper end of the drive plate and the magnet at the lower end of the connecting plate attract each other. This design not only simplifies the transmission mechanism and reduces transmission noise, but also improves transmission efficiency. At the same time, the use of magnets ensures a tight connection between the drive plate and the connecting plate, so that the drive motor's rotation of the drive plate can be transmitted to the connecting plate, realizing the adjustment of the clamping position and preventing gaps and errors in the transmission process.

[0020] The beneficial effects of this utility model are:

[0021] (1) The valve clamping device for valve processing described in this utility model has a push rod body that facilitates the movement and adjustment of the slider, can adjust the spacing between the clamping parts, improves the ease of operation of the device, and ensures that the clamping parts firmly clamp the valve.

[0022] (2) The valve clamping device for valve processing described in this utility model can adjust different clamping parts to ensure that the inner diameter of the clamping parts is compatible with the size of the valve to be clamped, providing a stable clamping environment for the valve. This design simplifies the transmission mechanism, improves the transmission efficiency, and ensures the precise movement of the clamping parts, so that the same set of devices can clamp multiple types of valves, and ensures the clamping tightness between the clamping parts and the valve, thereby reducing production costs.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the valve clamping device for valve processing according to this utility model includes a processing table 1, a slider 2, a drive motor 3, and a connecting plate 22. The processing table 1 has a sliding groove 13 inside, and sliders 2 are slidably installed on both sides of the inner wall of the sliding groove 13. A damping bearing 27 is embedded in the slider 2, and a rotating shaft 21 is interference-fitted inside the damping bearing 27. A support column 23 is welded to the outer wall of the upper end of the rotating shaft 21. A circular array of fitting grooves 24 is opened on the outer wall of the support column 23, and fitting blocks 25 are provided inside the fitting grooves 24. Drive motors 3 are provided on both sides of the lower outer wall of the processing table 1, and rectangular array of support legs 14 are installed on the lower outer wall of the processing table 1.

[0032] During use, the slide 13 ensures the stable horizontal movement of the slider 2 and allows adjustment of the spacing between the clamping parts 26. The clamping parts 26 can clamp and fix the valve. The interference fit of the damping bearing 27 and the rotating shaft 21 ensures the stable rotation of the support column 23. After the rotating shaft 21 is rotated to adjust the angle, it can adjust the clamping parts 26. It ensures that the inner diameter of the clamping parts 26 is compatible with the size of the valve to be clamped, providing a stable clamping environment for the valve. The assembly of the fitting groove 24 and the fitting block 25 ensures the stable position of the clamping parts 26. The support leg 14 can raise the processing table 1, ensuring that the working height of the processing table 1 meets the requirements.

[0033] For synchronized rotation, for example, such as Figure 4 As shown, a connecting plate 22 is installed on the lower outer wall of the rotating shaft 21, and the connecting plate 22 is located at the lower end of the slider 2.

[0034] In use, the drive motor 3 can drive the support column 23 to rotate through the connecting plate 22, thereby adjusting the position of the clamping part 26 to ensure that the inner diameter of the clamping part 26 is compatible with the size of the valve. This design simplifies the transmission mechanism, improves transmission efficiency, and ensures the precise movement of the clamping parts.

[0035] To clamp the valve, for example, such as Figure 1 As shown, a clamping member 26 is welded to the outer wall of one end of the interlocking block 25. The clamping member 26 has a clamping groove inside, and the inner diameter of the clamping groove is inconsistent.

[0036] During use, the inner diameter of the clamping grooves inside the clamping member 26 is inconsistent, which can accommodate valves of different sizes and shapes. This design increases the adaptability of the device, allowing the same device to clamp multiple types of valves, while ensuring the tightness of the clamping between the clamping member 26 and the valve, thus reducing production costs.

[0037] For fixed connections, for example, such as Figure 4 As shown, a bolt is provided on one side of the outer wall of the fitting block 25, and the fitting block 25 is connected to the inner wall of the fitting groove 24 by the bolt.

[0038] During use, the detachable design of the bolts facilitates the replacement and maintenance of the clamping component 26. At the same time, the bolt connection also ensures the stability of the fitting block 25 in the fitting groove 24 and prevents the clamping component 26 from loosening during use.

[0039] To facilitate clamping, for example, such as Figure 2 As shown, push rod bodies 11 are provided on both sides of the upper outer wall of the processing table 1. One end of the outer wall of the push rod body 11 is connected to the slider 2. A fastener 12 is provided on one side of the outer wall of the push rod body 11, and the push rod body 11 is connected to the upper outer wall of the processing table 1 through the fastener 12.

[0040] During use, the fastener 12 allows the push rod body 11 to be more securely connected to the processing table 1, preventing the push rod body 11 from sliding or shifting during the processing. At the same time, the push rod body 11 also facilitates the movement and adjustment of the slider 2, and can adjust the spacing between the clamping parts 26, thus improving the ease of operation of the device.

[0041] To fix the usage location, for example, such as Figure 5 As shown, support frames 31 are installed on both sides of the outer wall of the drive motor 3. A base plate 32 is welded to the upper outer wall of the support frame 31. The base plate 32 has screws arranged in a rectangular array inside, and the base plate 32 is connected to the lower outer wall of the processing table 1 by screws.

[0042] During use, the design of the support frame 31 and the base plate 32 provides stable support for the drive motor 3, ensuring its smooth operation. The screw connection allows the base plate 32 to be easily installed on the lower end of the processing table 1, and also facilitates the disassembly and maintenance of the drive motor 3.

[0043] For synchronized rotation, for example, such as Figure 5 As shown, a drive plate 33 is provided on the upper outer wall of the drive motor 3. The drive plate 33 is located at the lower end of the connecting plate 22. Magnets 34 are embedded in the outer walls of the drive plate 33 and the connecting plate 22 on opposite sides.

[0044] During use, the magnet 34 at the upper end of the drive plate 33 and the magnet 34 at the lower end of the connecting plate 22 attract each other. This design not only simplifies the transmission mechanism and reduces transmission noise, but also improves transmission efficiency. At the same time, the use of magnet 34 ensures a tight connection between the drive plate 33 and the connecting plate 22, so that the drive motor 3 can transmit the rotation of the drive plate 33 to the connecting plate 22, thereby adjusting the position of the clamping member 26 and preventing gaps and errors in the transmission process.

[0045] When using this utility model, a suitable clamping part 26 is selected according to the size of the valve to be processed, and the selected clamping part 26 is fixed in the fitting groove 24 of the support column 23 by bolts to ensure that the fitting block 25 and the fitting groove 24 are tightly fitted to prevent loosening.

[0046] Start the drive motor 3. The drive motor 3 drives the support column 23 to rotate through the connecting plate 22. Observe the rotation of the support column 23 and adjust the angle of the support column 23 as needed to ensure that the inner diameter of the clamping part 26 used is compatible with the size of the valve.

[0047] The position of the slider 2 in the slide groove 13 is adjusted by using the push rod body 11, thereby changing the spacing between the clamping members 26, placing the valve in the clamping groove, and using the push rod body 11 to apply clamping force to the clamping members 26 to fix the valve.

[0048] It should be noted that this utility model is a valve clamping device for valve processing. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
