Technical Field

[0001] This application relates to the field of valve body polishing technology, specifically a polishing device for valve body processing. Background Technology

[0002] Valve body polishing is an important process in valve manufacturing and maintenance. The main purpose of polishing is to improve the surface finish of the valve body, thereby reducing frictional resistance during fluid flow and improving valve performance.

[0003] For example, the patent with publication number CN220533808U specifically discloses a belt polishing machine, which includes a bracket and a belt assembly mounted on the bracket. The belt assembly includes a drive wheel, a driven wheel and a belt. The drive wheel and the driven wheel are both mounted on the bracket, and the belt is wound around the drive wheel and the driven wheel.

[0004] In the aforementioned patent, the belt polishing machine mainly drives the belt to rotate under the cooperation of the drive wheel and the driven wheel, and performs polishing operations on the valve body. However, during the polishing process of the belt polishing the valve body, metal debris may be attached to the belt due to the grinding of the belt. The metal debris attached to the belt moves with the belt and may cause scratches or marks on the surface of the valve body, thus affecting the smoothness after polishing. Therefore, it is necessary to provide a polishing device for valve body processing to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] like Figure 1As shown, this application provides a polishing device for valve body processing, including a worktable 1 and a sandpaper grinder 3 mounted on the worktable 1. The sandpaper grinder 3 is used to grind the valve body. The sandpaper grinder 3 includes a base plate 32 slidably mounted on the worktable 1 and drive wheels (not shown in the figure) with bearings mounted on the base plate 32. In this application, there are three sets of drive wheels, and the three sets of drive wheels are arranged in a triangular pattern. The number of drive wheels depends on the actual situation and is not limited here.

[0024] A sanding belt 31 for polishing the valve body is installed on the outer ring of the three sets of drive wheels, and a first motor (not shown in the figure) is connected to the bottom of one set of drive wheels. The drive wheel can rotate under the drive of the first motor, and the rotational force of the drive wheel drives the sanding belt 31 to move. The base plate 32 is adapted to move under the action of external driving force so that the sanding belt 31 moves closer to the valve body to polish the valve body. The external driving force can be driven by screw transmission, which is not limited here.

[0025] Meanwhile, a base 25 for placing the valve body is mounted on the bearing on the workbench 1, and a pressing mechanism 2 is provided on the top of the base 25. The pressing mechanism 2 is used to limit and press the valve body on the base 25. The pressing mechanism 2 includes a frame 21 mounted on the workbench 1 and a hanging plate 23 slidably mounted on the frame 21. A cylinder 22 is mounted on the frame 21. The output end of the cylinder 22 is connected to the hanging plate 23. A second motor 24 is mounted at the bottom of the hanging plate 23, and a pressure column 241 is fixed to the output end of the second motor 24.

[0026] The hanging plate 23 is adapted to be lifted and lowered under the drive of the cylinder 22, and indirectly drives the pressure column 241 on the second motor 24 to move closer to the platform 25, so that the pressure column 241 presses and limits the valve body on the platform 25, and the second motor 24 rotates, and through the cooperation of the platform 25, the valve body is rotated.

[0027] Then, under the action of external driving force, the base plate 32 drives the sanding belt 31 to approach the valve body on the platform 25, and the first motor operates and drives the sanding belt 31 to move through the cooperation of the drive wheel to polish the edge of the valve body.

[0028] like Figures 1-3 As shown, two sets of cleaning sections 4 are installed on the workbench 1. The cleaning sections 4 are opposite to the end corners of the sanding belt 31 and are used to brush away metal debris from the sanding belt 31.

[0029] The cleaning unit 4 includes a base 41 fixed on the workbench 1 and a slide 42 slidably mounted on the base 41. The base 41 is angled and parallel to the inclined side of the sander 3. A roller brush 43 is rotatably mounted on the slide 42. The roller brush 43 is made of nylon fiber and is adapted to abut against the sanding belt 31. Thus, the slide 42 is adapted to slide along the base 41 under the action of external force and move closer to or away from the corner of the sander 3.

[0030] Meanwhile, a drive unit 44 is provided at the end of the base 41. The drive unit 44 is used to control the sliding distance of the carriage 42. The drive unit 44 includes a guide frame 441 fixed on the base 41 and a guide shaft 442 that slides through the guide frame 441. The end of the guide shaft 442 is fixedly connected to the carriage 42.

[0031] A right-angle wrench 443 is hinged at the end of the guide frame 441, and a damping shaft is provided at the connection between the guide frame 441 and the right-angle wrench 443 so that the right-angle wrench 443 can only rotate under the action of external force. A connecting rod 444 is provided between the right-angle end of the right-angle wrench 443 and the guide shaft 442, and the two ends of the connecting rod 444 are respectively hinged to the right-angle end of the right-angle wrench 443 and the guide shaft 442.

[0032] When the position of the slide 42 needs to be adjusted, pressure is applied to the right-angle wrench 443 to make it rotate. With the cooperation of the connecting rod 444, the guide shaft 442 is driven to move along the guide frame 441 and the slide 42 slides on the base 41. At the same time, under the action of the damping shaft, when the external force on the right-angle wrench 443 disappears, the position of the right-angle wrench 443 is fixed, thereby achieving the purpose of adjusting the position of the roller brush 43 so that the roller brush 43 can clean the sanding belt 31 at different distances.

[0033] In summary, the rotation of the right-angle wrench 443 drives the connecting rod 444 to move, and with the cooperation of the connecting rod 444, it drives the guide shaft 442 to move, thereby causing the roller brush 43 on the slide 42 to move closer to or away from the sanding belt 31. At the same time, under the action of the damping shaft, the right-angle wrench 443 is appropriately fixed in position, thereby achieving the purpose of adjusting the position of the roller brush 43 and solving the problem that metal debris easily adheres to the sanding belt 31 and scratches the valve body during the polishing process.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations are possible for those skilled in the art. Any improvements and modifications made within the spirit and principles of this application, without departing from its principles, should also be considered within the scope of protection of this application.
