Description

Technical Field

[0001] This utility model relates to the field of burr removal and polishing technology for butterfly valve body surface, specifically a surface polishing device for butterfly valve processing. Background Technology

[0002] A butterfly valve is a type of valve that controls the flow of media in a pipeline by rotating a disc-shaped disc. It has both shut-off and throttling functions and is widely used in water treatment, energy, chemical and other fields. The core components of a butterfly valve include the valve body, valve stem, disc and sealing ring.

[0003] In the prior art, publication number "CN221065705U" discloses a surface polishing device for butterfly valve processing, including a processing housing, a support leg fixedly installed at the bottom of the processing housing, and a processing component disposed on the side wall of the processing housing. The processing component includes a polishing mechanism installed on the side wall of the processing housing, the polishing mechanism being located on the inner wall of the processing housing, and a stabilizing mechanism installed on the side wall of the processing housing, the stabilizing mechanism being located below the polishing mechanism. This invention solves the problem that while existing devices use a polishing device to polish butterfly valves during processing, this device lacks a dust removal function. A large amount of dust is generated during polishing of the butterfly valve surface, requiring operators to clean the dust afterward, increasing their workload. Furthermore, if the dust enters the operator's mouth, it can affect their health.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In the aforementioned device and existing technology, dust collection during the grinding process is achieved through a dust removal structure to avoid affecting manual clamping. The inner cavity of the butterfly valve body needs to be deburred, and the outer surface of the butterfly valve body needs to be ground to remove any residual coating, so as to facilitate the application of primer for rust prevention on the outer surface of the butterfly valve body. If it is not possible to grind both sides of the butterfly valve body during the grinding process, it will increase the number of processing steps for the butterfly valve body and affect the processing efficiency of the butterfly valve grinding.

The vertical lifting frame 2 is installed on both sides of the material discharge chamber 9. A material discharge guide plate 13 is installed on one end of the conveyor table 1 near the material discharge chamber 9. A butterfly valve body inner and outer contact grinding unit is provided between adjacent vertical lifting frames 2 for contact grinding to remove burrs and floating rust layers from the butterfly valve body. A butterfly valve body grinding rotation adjustment unit is provided in the bottom area of ​​the material discharge guide plate 13 for rotating and adjusting the grinding position of the butterfly valve body during the grinding step. A conveyor belt 11 is installed on the surface of the conveyor table 1.

[0027] The surface of the feeding bin 9 is inclined, and a buffer sleeve 91 is provided on the surface of the feeding bin 9.

[0028] The feeding guide plate 13 is inclined, and the surface of the feeding guide plate 13 is provided with guide inclined blocks 14, which are symmetrically arranged in two sets.

[0029] The inner and outer contact grinding unit of the butterfly valve body includes an outer grinding part, which includes a grinding cover 4. A positioning ring 22 is installed in the middle section of the outer surface of the grinding cover 4. Fixed arms 21 are installed on both sides of the positioning ring 22. The fixed arms 21 are fixed to the moving end of the vertical lifting frame 2. An annular guide rail 41 is installed on the top of the grinding cover 4. A grinding inner shell 421 is provided in the inner cavity of the grinding cover 4. The top of the grinding inner shell 421 is fixed to the rotating end of the annular guide rail 41. A flexible steel brush layer 422 is provided in the inner cavity of the grinding inner shell 421. The flexible steel brush layer 422 makes contact grinding with the outer surface of the butterfly valve body.

[0030] The inner and outer contact grinding unit of the butterfly valve body also includes an inner grinding part, which includes an arc-shaped fixed shell 42. The arc-shaped fixed shell 42 is installed on the top of the annular guide rail 41. The arc-shaped fixed shell 42 is arranged in multiple annular arrays. A vertical sleeve 43 is installed in the central area of ​​the top of the arc-shaped fixed shell 42. A high-speed motor 45 is embedded in the surface of the vertical sleeve 43. An installation turntable 46 is installed on the rotating end of the high-speed motor 45. A transmission rotating shell 44 is rotatably mounted on the outer surface of the vertical sleeve 43. The bottom of the transmission rotating shell 44 is fixed to the top of the installation turntable 46. An adsorption gas chamber plate 47 is installed at the bottom of the installation turntable 46. An external sleeve 48 is installed on the outer surface of the adsorption gas chamber plate 47. A flexible steel brush layer 481 is provided on the outer surface of the external sleeve 48. The flexible steel brush layer 481 contacts and grinds the inner wall surface of the butterfly valve body.

[0031] In this embodiment, the annular guide rail 41 slowly polishes the outer surface of the butterfly valve body with the inner shell 421 and the flexible steel brush layer 422, ensuring that the residual oil coating on the outer surface of the butterfly valve body is fully removed. The high-speed motor 45 drives the mounting turntable 46 and the flexible steel brush layer 481 to perform variable-speed polishing on the inner wall of the butterfly valve body. First, the protruding burrs are removed by fast polishing, followed by slow polishing until the inner wall of the butterfly valve body is polished smooth. During the polishing process, the adsorption air chamber plate 47 continuously extracts the gas in the polishing area to reduce dust in the area. At the same time, some metal debris can be adsorbed and fixed by the magnetic column 331 to further reduce the impact of debris generated during polishing, while ensuring the polishing effect of the inner and outer layers of the butterfly valve body surface.

[0032] Example 2:

[0033] Based on Embodiment 1, this embodiment takes into account that if the butterfly valve body cannot be turned over during the grinding process, the anti-rust paint on the other side of the butterfly valve body will have poor adhesion. At the same time, contact grinding will cause the butterfly valve body to overheat and make it impossible to manually clamp and turn it over. Therefore, this embodiment is equipped with a butterfly valve body grinding rotation adjustment unit to ensure that both sides of the butterfly valve can be effectively ground, thus avoiding the above problems.

[0034] The butterfly valve body grinding rotation adjustment unit includes a positioning part, the positioning part includes a rotating base plate 33, the grinding chamber 3 is symmetrically mounted with electric hinges 32, the rotating base plate 33 is mounted on the rotating end of the electric hinges 32, the rotating base plate 33 is provided with magnetic suction columns 331 on the surface of the rotating base plate 33, the grinding chamber 3 is provided with a grinding cavity 31 inside, and the magnetic suction columns 331 are inserted into the grinding cavity 31.

[0035] The butterfly valve body grinding rotation adjustment unit also includes a rotation part, which includes a fixing frame 34. The fixing frame 34 is configured in two sets and is installed on both sides of the grinding chamber 3. A retaining ring 35 is installed on the surface of the fixing frame 34. A telescopic cylinder 36 is embedded in the surface of the retaining ring 35. An electric turntable 37 is installed on the movable end of the telescopic cylinder 36. A support column 38 is installed on the rotating end of the electric turntable 37. One end of the support column 38 moves through the grinding chamber 3, and anti-slip rubber dots are provided on the surface of one end of the support column 38.

[0036] In this embodiment, the support column 38 is inserted into the grinding chamber 3 by driving the telescopic cylinder 36, and the butterfly valve body is fixed by clamping the two sets of support columns 38. At this time, the electric hinge 32 is driven to unfold the rotating base plate 33 downward, and then the electric turntable 37 is controlled to drive the support column 38 and the butterfly valve body to rotate and flip.

[0037] Working principle: The operator loads the butterfly valve body to be ground from one end of the top of the conveyor belt 11, and then drives the conveyor belt 11 to transport the butterfly valve body. When the butterfly valve body is transported by the conveyor belt 11 to the surface of the unloading guide plate 13, the butterfly valve body falls into the grinding chamber 3 under the guidance of the guide block 14 on the surface of the unloading guide plate 13. Then, after calibration by the calibration personnel, the butterfly valve body is calibrated and placed in the center area of ​​the grinding chamber 3, and is magnetically positioned and fixed by the magnetic column 331 in the grinding cavity 31. This ensures that in the subsequent grinding process, the flexible steel brush layer 422 and the flexible steel brush layer 481 can smoothly and effectively contact the outer surface and inner wall of the butterfly valve body for grinding, ensuring the grinding effect of the butterfly valve body.

[0038] Once the butterfly valve body is properly aligned and installed, the vertical lifting frame 2 can be driven to descend via the fixed arm 21 and positioning ring 22. The grinding cover 4 descends and inserts into the grinding chamber 3. Part of the flexible steel brush layer 422 adheres to the outer surface of the butterfly valve body, while part of the flexible steel brush layer 481 adheres to the inner wall of the butterfly valve body. Then, by driving the annular guide rail 41 and high-speed motor 45, the annular guide rail 41 slowly grinds the outer surface of the butterfly valve body, carrying the grinding inner shell 421 and the flexible steel brush layer 422, ensuring the smooth surface of the butterfly valve body. The residual oil coating on the surface is thoroughly removed by grinding. The high-speed motor 45 drives the mounting turntable 46 and the flexible steel brush layer 481 to perform variable-speed grinding on the inner wall of the butterfly valve body. First, the protruding burrs are removed by fast grinding, followed by slow grinding until the inner wall of the butterfly valve body is smooth. During the grinding process, the adsorption air chamber plate 47 continuously extracts the gas in the grinding area to reduce dust in the area. At the same time, some metal debris can be adsorbed and fixed by the magnetic column 331 to further reduce the impact of debris generated during grinding, while ensuring the grinding effect of the inner and outer layers of the butterfly valve body surface.

[0039] After the upper surface of the butterfly valve body is polished, the polishing cover 4 can be reset by driving the vertical lifting frame 2. Then, the support column 38 can be inserted into the polishing chamber 3 by driving the telescopic cylinder 36, and the butterfly valve body is fixed by clamping the two sets of support columns 38. At this time, the electric hinge 32 is driven to unfold the rotating base plate 33 downward, and then the electric turntable 37 is controlled to drive the support column 38 and the butterfly valve body to rotate and flip. After the butterfly valve body has completed the flipping and adjustment, the rotating base plate 33 can be reset by driving the electric hinge 32. After the reset is completed, the other side of the butterfly valve body can be effectively polished to ensure that both sides of the butterfly valve body are effectively polished and to ensure the polishing efficiency of the butterfly valve body.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
