Description

Technical Field

[0001] This application relates to the field of valve body processing technology, and in particular to a grinding device for valve body processing. Background Technology

[0002] Currently, the valve body is the main structure of a valve, serving as the outer shell for connecting pipelines, forming flow channels, and supporting internal components (such as the valve disc and valve stem). Its core functions include pressure bearing and sealing, regulating fluid flow or shut-off, and fixing the drive device. Valve bodies are mostly made of metal (cast iron, stainless steel, etc.) or non-metallic materials (such as PVC), and can be classified by structure as straight-through, angle, etc. Manufacturing processes include casting and forging. Its design directly affects the valve's pressure resistance, sealing performance, and applicable media (such as corrosive, high-temperature, and high-pressure environments), making it a key component for valve performance. Typical examples include the rotary valve body of a ball valve or the Z-shaped flow channel structure of a gate valve.

[0003] A Chinese patent with publication number CN218518337U discloses a valve body grinding device, including a support, a grinding table rotatably connected to the top surface of the support, a first drive motor fixedly connected to the bottom surface of the support, one end of the output shaft of the first drive motor fixedly connected to the grinding table, a drive bevel gear rotatably connected to the bottom surface of the grinding table, a second drive motor fixedly connected inside the grinding table, one end of the output shaft of the second drive motor fixedly connected to the drive bevel gear, a set of first threaded screws rotatably connected to the inner wall of the grinding table, a driven bevel gear fixedly connected to one end of each set of first threaded screws, the peripheral surfaces of each set of driven bevel gears meshing with the drive bevel gears, a moving block threadedly connected to the peripheral surfaces of each set of first threaded screws, and a clamping rod fixedly connected to the top surface of each set of moving blocks.

[0004] In related technologies, the valve body is placed on a grinding platform, and then the grinding platform drives the valve body to rotate. As the valve body rotates, the grinding blocks grind the outer surface of the valve body.

[0005] Regarding the aforementioned technologies, the inventors believe that burrs exist inside the valve body during the processing. If these burrs are not removed, they can easily affect the fluid flow and sealing performance within the valve body. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a grinding device for valve body processing, which solves the technical problem that if burrs are present inside the valve body during the processing and are not ground, they will easily affect the fluid flow and sealing performance inside the valve body.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0013] Furthermore, the two sliding frames arranged opposite each other are provided with slide rails, and the slide rails are formed with slide grooves. A crossbar is provided between the two sliding frames. The crossbar is slidably installed in the slide groove. A pressing cylinder is provided on the crossbar.

[0025] In order 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.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a grinding device for valve body processing.

[0028] Reference Figure 1A grinding device for valve body processing includes a frame 1, on which a conveyor roller 11 is mounted. The conveyor roller 11 is rotatably mounted on the frame 1. When the valve body is placed on the frame 1, the conveyor roller 11 allows the valve body to slide on the frame 1. A drive assembly 2 and a grinding assembly 3 are provided on the frame 1. The drive assembly 2 drives the valve body to slide on the frame 1, and during the sliding process, the grinding assembly 3 grinds the valve body.

[0029] Reference Figure 2 The frame 1 is rectangular in shape. The drive assembly 2 includes a sliding frame 21, which is arranged opposite to each other along the width of the frame 1. In use, the valve body passes between the two sliding frames 21. The two sliding frames 21 have the same structure and function, therefore, only one set of sliding frames 21 will be described below.

[0030] A sliding frame 21 is equipped with a rotating shaft 211, and several rotating shafts 211 are spaced apart on the corresponding sliding frame 21. A conveyor belt 212 is mounted on the frame 1, and the conveyor belt 212 is fitted onto the rotating shaft 211. During use, the rotating shaft 211 rotates, and the conveyor belt 212 rotates on the sliding frame 21. To improve the ease of rotation of the conveyor belt 212 on the sliding frame 21, a sliding motor 22 is mounted on the frame 1. The output shaft of the sliding motor 22 is equipped with a drive gear 221, and one of the rotating shafts 211 is equipped with a driven gear 222. The drive gear 221 and the driven gear 222 mesh with each other. The sliding motor 22 drives the drive gear 221 to rotate, and the drive gear 221 drives the rotating shaft 211 to rotate through the driven gear 222. Since the conveyor belt 212 meshes with the rotating shaft 211, the conveyor belt 212 can rotate on the sliding frame 21.

[0031] In use, the valve body passes between the two sliding frames 21, and the conveyor belt 212 on the sliding frame 21 abuts against the valve body, so that the valve body can slide on the conveyor roller 11 during the rotation of the conveyor belt 212.

[0032] To enable the sliding frames 21 on both sides of the frame 1 to accommodate different types of valve bodies, allowing the valve bodies to slide on the frame 1, drive cylinders 23 are installed on both sides of the frame 1 in the width direction. The drive cylinders 23 are horizontally mounted on the frame 1, with one end of the piston rod facing towards the side closest to the sliding frame 21. One end of the piston rod passes through the sliding frame 21, and the sliding frame 21 and the piston rod of the drive cylinder 23 slide together. Furthermore, a support spring 231 is provided between the sliding frame 21 and the drive cylinder 23, and the support spring 231 abuts against the piston rod of the drive cylinder 23.

[0033] In use, the sliding frames 21 on both sides of the frame 1 move toward each other under the action of the drive cylinder 23, so that the conveyor belt 212 can press against the valve body. When there are protrusions on the surface of the valve body, the support spring 231 is compressed, so that the sliding frame 21 can adapt to the surface changes of the valve body.

[0034] Reference Figure 3 The grinding assembly 3 includes an adjusting block 31, which is slidably mounted on the frame 1 and slides vertically on the frame 1. A connecting rod 311 and a drive motor 312 are provided on the adjusting block 31. The drive motor 312 is mounted on the adjusting block 31. One end of the connecting rod 311 is connected to the output shaft of the drive motor 312, and the other end extends horizontally to one side. Brush bristles 313 are formed on the connecting rod 311. In use, the valve body is conveyed under the drive of the conveyor belt 212. One end of the connecting rod 311 passes through the valve body. During the grinding process inside the valve body, the drive motor 312 drives the connecting rod 311 to rotate, and the brush bristles 313 on the connecting rod 311 grind the valve body, removing burrs from the valve body.

[0035] A lifting cylinder 32 is installed on the frame 1. The lifting cylinder 32 is installed on the frame 1 and is vertically arranged. One end of the piston rod of the lifting cylinder 32 is connected to the adjusting block 31. When in use, the lifting cylinder 32 drives the adjusting block 31 to move up and down on the frame 1, so that the connecting rod 311 can be inserted into the inner cavity of different valve bodies, thereby improving the cleaning effect of the bristles 313 on the connecting rod 311 on the inner cavity of the valve body.

[0036] Reference Figure 4 Furthermore, to improve the polishing effect of the valve body, each of the two sliding frames 21 is equipped with a slide rail 33, and the slide rail 33 has a groove 331. The length direction of the groove 331 is parallel to the sliding direction of the sliding frame 21 on the frame 1. A crossbar 34 is provided between the two sliding frames 21, spanning across the two sliding frames 21, and the crossbar 34 is slidably mounted on the groove 331 of the slide rail 33. Furthermore, a pressing cylinder 341 is provided on the crossbar 34. The pressing cylinder 341 is mounted on the crossbar 34, and one end of the piston rod of the pressing cylinder 341 extends through the crossbar 34 towards the side near the conveyor roller 11.

[0037] A pressure plate 342 is provided at one end of the piston rod of the pressing cylinder 341, and the pressure plate 342 is mounted on the piston rod of the pressing cylinder 341. Brush bristles 313 are formed on the side of the pressure plate 342 near the conveying roller 11. The pressing cylinder 341 drives the pressure plate 342 to move towards the side closer to the valve body. When the brush bristles 313 on the pressure plate 342 press against the valve body, the brush bristles 313 on the pressure plate 342 polish the valve body, thereby removing the burrs on the valve body.

[0038] Reference Figure 5 Furthermore, a support plate 35 is provided on the side of the frame 1 near the conveyor roller 11. Brush bristles 313 are formed on the support plate 35. One end of the brush bristles 313 is connected to the support plate 35, and the other end passes between two adjacent conveyor rollers 11. In use, the pressure plate 342 and the brush on the support plate 35 polish the outer surface of the valve body.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
