Description

Technical Field

[0001] This application relates to the field of grinding equipment, and more particularly to a pneumatic grinding assembly. Background Technology

[0002] Grinding, a surface modification technique, generally refers to a processing method that uses a rough object (such as sandpaper containing high-hardness particles) to alter the physical properties of a material's surface through friction. Its main purpose is to achieve a specific surface roughness or to smooth the surface of a workpiece. In traditional grinding processes, grinding equipment is typically used to grind the workpiece surface, such as grinding machines, pneumatic grinders, abrasive wheel grinders, angle grinders, etc. Pneumatic grinders are generally used for metal grinding, cutting, paint removal, and putty sanding.

[0003] Existing pneumatic grinding components generate a large amount of dust during actual operation. If the dust is not treated, it will directly pollute the air. At the same time, the existing grinding components do not have dust collection, which affects the normal grinding work of the workers. Utility Model Content

[0004] In order to solve the problem of dust pollution in the air generated during the operation of existing grinding components, this application provides a pneumatic grinding component.

[0005] The pneumatic grinding assembly provided in this application adopts the following technical solution:

[0006] A pneumatic grinding assembly includes a housing and a collection assembly mounted on the housing. The collection assembly includes a bracket fixedly connected to the housing, and a collection box is clamped on the bracket. A filter cover is fixedly connected to the bottom outer wall of the collection box. A circular opening is provided on one side outer wall of the collection box, and a fan is fixedly connected to the inner wall of the circular opening. A dust box is clamped to the inner wall of the collection box.

[0007] By adopting the above technical solution, a collection component is set on the outer shell of the grinding component. The collection component facilitates the collection of dust generated during grinding, thereby preventing dust from being raised and causing a decline in air quality. The detachable dust box in the collection box facilitates the collection of dust, thereby preventing secondary dust raising. The fan facilitates the suction of diffused dust into the dust box. The filter cover facilitates the preliminary filtration of dust, preventing large impurities in the air from entering the dust box.

[0008] The bottom inner wall of the collection box is fixedly connected to a connector that communicates with the filter cover, and the bottom outer wall of the ash box is fixedly connected to a connecting sleeve that connects to the connector.

[0009] By adopting the above technical solution, the connector and the filter cover are connected, and the connector and the connecting sleeve can be directly engaged, thereby facilitating the introduction of the dust collected by the filter cover into the dust box.

[0010] A second connector, which is connected to the ash box, is fixedly connected to one side of the outer wall of the ash box, and the inlet of the fan is connected to the second connector through a pipe.

[0011] By adopting the above technical solution, the connection head two is convenient for connecting to the fan. The fan is designed to easily draw the ash box into a negative pressure state, thereby facilitating the introduction of external dust into the ash box.

[0012] The same dust removal filter cloth is fixedly connected to the inner walls of both sides of the ash box, and an ash outlet is opened on one side of the outer wall of the ash box, and a sealing cap is snapped into the inner wall of the ash outlet.

[0013] By adopting the above technical solution, the dust collection filter cloth is designed to keep the collected dust in the dust box, the dust outlet is designed to allow the collected dust to be directly discharged, and the sealing cover is designed to seal the dust outlet, thereby ensuring the sealing performance of the dust box.

[0014] The top outer wall of the ash box has an opening, and a pull rod is slidably connected to the inner wall of the opening.

[0015] By adopting the above technical solution, the opening at the top of the gray box facilitates the sliding installation of the pull rod, which has a T-shaped structure.

[0016] One end of the pull rod is fixedly connected to an impact block, and the impact block is in contact with the dust removal filter cloth. A spring is sleeved on the outer wall of the pull rod.

[0017] By adopting the above technical solution, the spring is directly compressed when the pull rod pulls the impact block upward. When the pull rod is released, the impact block directly impacts the dust removal filter cloth, thus facilitating the removal of impurities adhering to the dust removal filter cloth.

[0018] The inner wall of the outer casing is rotatably connected to a rotating disk, and the top outer wall of the outer casing is fixedly connected to a handle. The top outer wall of the handle is fixedly connected to a housing, the outer wall of the handle is fixedly connected to a switch box, and the outer wall of the outer casing is fixedly connected to an air pipe.

[0019] By adopting the above technical solution, the grinding disc is directly driven to grind the parts when the rotating disc in the outer shell rotates. The handle makes it easy to hold the grinding component, and the switch box makes it easy to control the rotation of the rotating disc.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application provides a collection component on the housing of the grinding component. The collection component facilitates the collection of dust generated during grinding, thereby preventing dust from polluting the air when it is raised. The collection component also facilitates the collection of dust in the dust box, effectively preventing the dust from being raised again.

[0022] 2. This application provides a mounting bracket on the outer casing, which facilitates the snap-fit ​​and fixing of the collection box. This allows for easy installation and fixation of the collection components onto the outer casing when needed. The dust filter cloth inside the ash box helps retain dust within the ash box. The cooperation between the pull rod, the impact block, and the spring facilitates the cleaning of impurities adhering to the dust filter cloth, thereby preventing the dust filter cloth from being clogged by dust.

A housing 3 is fixedly connected to the top outer wall of the handle 2, and a switch box 4 is fixedly connected to the outer wall of the handle 2. An air pipe 5 is fixedly connected to the outer wall of the housing 1. When the rotating disk 6 in the housing 1 rotates, it directly drives the grinding disk to grind the parts. The handle 2 is designed for easy hand holding of the grinding assembly, and the switch box 4 is designed for easy control of the rotation of the rotating disk 6.

[0031] Reference Figure 2-3The collection component 7 includes a bracket 8 fixedly connected to the outer shell 1, and a collection box 9 is clipped onto the bracket 8. A filter cover 10 is fixedly connected to the bottom outer wall of the collection box 9. A circular opening is opened on one side outer wall of the collection box 9, and a fan 11 is fixedly connected to the inner wall of the circular opening. A dust box 14 is clipped onto the inner wall of the collection box 9. A connector 12 connected to the filter cover 10 is fixedly connected to the bottom inner wall of the collection box 9. A connecting sleeve 15 connected to the connector 12 is fixedly connected to the bottom outer wall of the dust box 14. A connector 2 13 connected to the dust box 14 is fixedly connected to one side outer wall of the dust box 14. The inlet of the fan 11 is connected to the connector 2 13 through a pipe. The same dust removal filter cloth 16 is fixedly connected to both sides inner walls of the dust box 14. A dust outlet is opened on one side outer wall of the dust box 14, and a sealing cover 20 is clipped onto the inner wall of the dust outlet.

[0032] In use, the collection component 7 facilitates the collection of dust generated during grinding, thereby preventing dust from rising and causing a decline in air quality. The detachable dust box 14 in the collection box 9 facilitates dust collection, thereby preventing secondary dust re-entrainment. The fan 11 facilitates the suction of diffused dust into the dust box 14. The filter cover 10 facilitates preliminary filtration of dust, preventing large impurities in the air from entering the dust box 14. The connector 13 facilitates connection with the fan 11. The fan 11 facilitates creating a negative pressure state in the dust box, thereby facilitating the introduction of diffused dust from the outside into the dust box 14. The dust removal filter cloth 16 facilitates the retention of collected dust in the dust box 14. The dust outlet facilitates the direct discharge of collected dust. The sealing cover 20 facilitates the sealing of the dust outlet, thereby ensuring the sealing performance of the dust box 14.

[0033] Reference Figure 3-4 An opening is provided on the top outer wall of the ash box 14, and a pull rod 17 is slidably connected to the inner wall of the opening. An impact block 18 is fixedly connected to one end of the pull rod 17, and the impact block 18 is in contact with the dust removal filter cloth 16. A spring 19 is sleeved on the outer wall of the pull rod 17. When the pull rod 17 pulls the impact block 18 upward, it directly compresses the spring 19. When the pull rod 17 is released, the impact block 18 directly impacts the dust removal filter cloth 16, thereby facilitating the removal of impurities adhering to the dust removal filter cloth 16.

[0034] The implementation principle of a pneumatic grinding component in this application embodiment is as follows: When using the component 7, the collection box 9 is first attached to the mounting base 8, and the air supply pipe is connected to the air pipe 5. When the operator holds the handle 2 and presses the switch box 4, the rotating disk 6 rotates, directly driving the grinding disk to grind the material. At the same time, the fan 11 in the collection box 9 starts. The fan 11 directly passes through the filter cover 10 on the collection box 9, and the filter cover 10 introduces the dust into the dust box 14. The connection head 12 and the connection head 2 are set to facilitate the disassembly and assembly of the dust box 14. The dust entering the dust box 14 is easily retained in the dust collection filter cloth 16. When it is necessary to clean the dust in the dust box 14, the pull rod 17 is pulled to drive the impact block 18 to compress the spring 19. When the pull rod 17 is released, the spring 19 directly drives the impact block 18 to impact the dust collection filter cloth 16, thereby easily shaking off the dust adhering to it.

[0035] 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.
