Description

Technical Field

[0001] This utility model relates to the field of aviation technology, specifically to a surface finishing device for the production of aviation parts. Background Technology

[0002] In patent application CN222874261U, a protective housing is included. A sand-collecting hopper is located on the lower end face of the protective housing, and a support bracket is fixedly mounted on the upper end face of the protective housing. A sandblasting device is rotatably engaged at the center of the inner end face of the support bracket. A servo motor is located on the upper end face of the support bracket near the sandblasting device, and a drive synchronous pulley is fixedly mounted at the output end of the servo motor. The advantages are: during sandblasting, the feeding slide plate can cooperate with the protective housing for closed feeding, ensuring that the protective housing is a closed structure when the sandblasting drum is circling the workpiece, effectively improving the stability of sandblasting. Furthermore, the feeding slide plate contains multiple sets of workpieces, which can be circulated and fed simultaneously with the protective housing, effectively improving the efficiency of sandblasting the workpieces inside the feeding slide plate.

A brush 15 is installed at the bottom of the dustproof box 20.

[0025] In this embodiment, a sand discharge pipe 17 is provided on one side of the bottom of the impeller housing 21. One end of the sand discharge pipe 17 is fixedly connected to one side of the bottom of the impeller housing 21. A filter screen 19 is provided inside the impeller housing 21. The filter screen 19 is adapted to the impeller housing 21. An impeller 18 is provided at the bottom of the inner wall of the impeller housing 21. The impeller 18 is rotatably connected to the bottom and top of the inner wall of the impeller housing 21. A polishing disc 13 is provided on the other side of the bottom of the impeller housing 21. The top of the polishing disc 13 penetrates the bottom of the impeller housing 21 and extends into the interior of the impeller housing 21. The top of the polishing disc 13 is fixedly connected to the bottom of the impeller 18.

[0026] In this embodiment, an exhaust fan 5 is provided on one side of the cabinet 1, a waste box 4 is provided at the bottom of the exhaust fan 5, the top of the waste box 4 is fixedly connected to the bottom of the exhaust fan 5, an exhaust pipe 6 is provided at the top of the exhaust fan 5, one end of the exhaust pipe 6 is fixedly connected to the top of the exhaust fan 5, and the other end of the exhaust pipe 6 is fixedly connected to the other side of the impeller housing 21.

[0027] In this embodiment, an air tank 2 is provided on one side of the bottom of the inner wall of the cabinet 1, an air pump 3 is provided on the top of the air tank 2, a sandblasting pipe 8 is provided on one side of the air pump 3, one end of the sandblasting pipe 8 is fixedly connected to one side of the air pump 3, and the other end of the sandblasting pipe 8 is fixedly connected to the top of the sandblasting nozzle 16.

[0028] In this embodiment, a sand box 7 is provided on one side of the gas storage tank 2, and the sandblasting pipe 8 is connected to the top of the sand box 7.

[0029] In this embodiment, the other end of the sand discharge pipe 17 is fixedly connected to the top of the sand box 7.

[0030] In this embodiment, a turntable 10 is provided at the bottom of the inner wall of the cabinet 1, and a conveyor belt 9 is symmetrically provided on the front of the cabinet 1. The conveyor belt 9 is adapted to the turntable 10.

[0031] Working principle: During use, parts are conveyed sequentially to the area directly below the sandblasting device via conveyor belt 9 and turntable 10. High-pressure air is injected into the air tank 2 by air pump 3, and then the air valve is opened to allow air to pass through the sandblasting pipe 8 to the sandblasting nozzle 16. During this process, the rapid airflow creates a negative pressure inside the sand box 7, which in turn drives the sand particles through the sandblasting pipe 8 and out of the sandblasting nozzle 16 to perform sandblasting on the object to be sandblasted. Due to the use of the dust box 20 and the bottom brush 15, the sand particles are collected after being sprayed out and then driven by the exhaust fan 5 to be expelled. The air enters the impeller housing 21 through the inlet 14. Under the action of the filter screen 19 and gravity, it re-enters the sand box 7 through the sand discharge pipe 17. The air, after being initially filtered by the filter screen 19, continues to move under the action of the exhaust fan, thereby driving the impeller 18 to rotate. The polishing disc 13 at the bottom of the impeller 18 rotates coaxially to polish the surface of the sandblasted parts. The air containing a large amount of debris and impurities finally enters the waste box 4 through the exhaust pipe 6. Since the exhaust pipe 6, the sand discharge pipe 17, and the sandblasting pipe 8 are all designed with flexible hoses, the robotic arm can drive the sandblasting device to move within a small range.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
