Description

Technical Field

[0001] This utility model relates to the field of pressure ring processing technology, and in particular to a valve pressure ring processing device with clamping function. Background Technology

[0002] Valve pressure rings are crucial components in valve assemblies, widely used in industries such as petroleum, chemical, and power. Their primary function is to ensure the valve's sealing performance and safety under high pressure and high temperature environments by compressing the seal. The machining quality of the pressure ring directly affects the valve's performance and lifespan.

[0003] In existing technologies, clamping pressure rings typically employs external fixing methods, which are difficult to adapt to pressure rings of different sizes and shapes, limiting the range of products that can be processed. Unstable clamping methods can also easily lead to displacement of the pressure ring during processing, affecting machining accuracy and quality. Secondly, existing polishing equipment often uses a single polishing disc design, making it difficult to ensure uniform polishing of the pressure ring surface. This can easily result in localized excessive wear or uneven polishing, affecting the performance and lifespan of the pressure ring. Furthermore, the lack of effective fixing and locking mechanisms during polishing results in insufficient stability and positioning accuracy of the polishing disc, leading to unsatisfactory polishing results.

[0008] In a preferred embodiment, one end of the empty plate is fixedly connected to the inner wall of the empty tube, and a telescopic rod is provided on the inner wall of the empty tube. The inner wall of the empty tube is fixedly connected to one end of the telescopic rod, and a cone is provided on the other end of the telescopic rod. The other end of the telescopic rod is fixedly connected to one end of the cone, and the outer side of the cone slides in contact with the bottom end of the empty plate.

[0009] In a preferred embodiment, a movable arm is provided at one end of the side of the first grinding disc, and the side of the first grinding disc is fixedly connected to one end of the movable arm.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. With the extension of the telescopic rod, the cone block exerts an external force on the hollow plate, forcing it to extend out of the hollow tube. The clamping surface of the clamping plate will then fully contact and fix the inner side of the pressure ring. Therefore, by fixing it from the inside, pressure rings of different sizes and shapes can be adapted, expanding the range of products that can be processed and providing more flexibility for subsequent production. When polishing, since there are two polishing discs installed, and the two are in a semi-circular shape, the shape and relative position design of the two polishing discs can form a plane to contact both sides of the pressure ring during polishing, ensuring uniformity during polishing and avoiding local excessive wear or uneven polishing.

As a support point, the folding plate can effectively reduce the vibration and displacement of the device during operation, making the overall structure more stable, thereby improving the reliability and operational safety of the machine. It also helps to evenly distribute the load from the equipment and the processing process, reducing local stress concentration. Therefore, a second fixing part is designed at the other end. The design and installation of the second fixing part can effectively prevent the other end of the folding plate from tilting up due to the weight of the motor or the reaction force generated during operation.

[0024] Example 1

[0025] like Figures 1-4As shown, this utility model provides a technical solution: a valve pressure ring processing device with clamping function, comprising: a main body 1, a support mechanism 2 provided on the bottom side of the main body 1, the main body 1 including a hollow tube 11, a hollow plate 12 provided on the inner wall of the hollow tube 11, the inner wall of the hollow tube 11 and the outer side of the hollow plate 12 being slidably connected through, a clamping plate 17 provided on the top side of the hollow plate 12, the top side of the hollow plate 12 and the bottom end of the clamping plate 17 being slidably connected, a lead screw 18 provided on the inner wall of the clamping plate 17, the inner wall of the clamping plate 17 and the outer side of the lead screw 18 being threadedly connected, the hollow... Grinding disc 110 and grinding disc 112 are respectively provided on the outer side of the tube 11. The outer side of the empty tube 11 is in contact with the inner side of grinding disc 110 and grinding disc 112 respectively. An inner plate 13 is provided on the inner wall of the empty plate 12. The inner wall of the empty plate 12 is vertically slidably connected to one side of the inner plate 13. A spring piece 14 is provided on the top side of the inner plate 13. The top side of the inner plate 13 is fixedly connected to the bottom end of the spring piece 14. The top end of the spring piece 14 is fixedly connected to the inner wall of the empty plate 12. One end of the empty plate 12 is fixedly connected to the inner wall of the empty tube 11. The inner wall of the empty tube 11 is provided with a telescopic mechanism. One end of the telescopic rod 16 is fixedly connected to the inner wall of the hollow tube 11. A cone 15 is provided at the other end of the telescopic rod 16, and is fixedly connected to one end of the cone 15. The outer side of the cone 15 slides in contact with the bottom end of the hollow plate 12. A movable arm 111 is provided at one end of the side of the grinding disc 110, and is fixedly connected to one end of the movable arm 111. A telescopic rod 114 is provided at one end of the movable arm 111, and is fixedly connected to one end of the telescopic rod 114. Next, one end of the movable arm 111 is fixedly connected to one side of the grinding disc 112. One end of the grinding disc 110 is provided with a sleeve 19. One end of the grinding disc 110 is fixedly connected to one end of the sleeve 19. The inner wall of the sleeve 19 is slidably connected to the outer side of one end of the empty tube 11. One end of the sleeve 19 is fixedly connected to the output end of the motor 115. The inner wall of the movable arm 111 is provided with a fixing member 113. The inner wall of the movable arm 111 is threadedly connected to the outer side of the fixing member 113. One end of the fixing member is threadedly connected to the inner wall of the grinding disc 110.

[0026] In this embodiment, when the valve pressure ring processing device with clamping function is in use, by inserting the device into the middle end of the hollow tube 11, and then extending the length of the telescopic rod 16, the cone block 15 exerts an external force on the hollow plate 12, forcing it to extend out of the hollow tube 11. Subsequently, one side of the clamping plate 17 will contact the inner side of the pressure ring. At this time, the screw 18 is rotated, causing the clamping plate 17 to move on the hollow plate 12. As it moves continuously, the clamping surface of the clamping plate 17 will completely contact and fix the inner side of the pressure ring. Therefore, by fixing it from the inside, it is possible to... The range of processable products is expanded by using pressure rings of different sizes and shapes, providing more flexibility for subsequent production. During polishing, since there are two polishing discs installed, and both are semi-circular, the shape and relative position design of the two polishing discs can form a plane to contact both sides of the pressure ring during polishing, ensuring uniformity in the polishing process and avoiding localized excessive wear or uneven polishing. Subsequently, by fixing the fastener inside the first polishing disc 110, the position of the second polishing disc 112 can be limited, ensuring stability during the polishing process.

[0027] Secondly, when dealing with pressure rings of different thicknesses, the telescopic rod between the two grinding discs is retracted, which shortens the distance between the two grinding discs and allows for flexible adaptation to pressure rings of different thicknesses. This enables the device to handle pressure rings of various specifications and improves processing flexibility. During this process, the sleeve 19 on the grinding disc 110 will be extended so that the power source can keep up in time.

[0029] like Figure 1 As shown, the support mechanism 2 includes a folding plate 21. A fixing member 22 is provided on the inner wall of one end of the folding plate 21. The inner wall of one end of the folding plate 21 is threadedly connected to the outer side of the fixing member 22. A motor 115 is provided on the other end of the folding plate 21. The other end of the folding plate 21 is fixedly connected to the bottom side of the motor 115.

[0030] In this embodiment, the installed folding plate 21 is located on the bottom side of the motor 115. As a support point, the folding plate 21 can effectively reduce the vibration and displacement of the device during operation, making the overall structure more stable, thereby improving the reliability and operational safety of the machine, and helping to evenly distribute the load from the equipment and processing process, reducing local stress concentration. Since the motor 115 is installed at one end of the folding plate 21, in order to prevent the other end from tilting up, a fixing part 22 is designed at the other end. The design and installation of the fixing part 22 can effectively prevent the other end of the folding plate 21 from tilting up due to the weight of the motor 115 or the reaction force generated during operation, thereby ensuring the balance of the entire device.
