This requires repeated rework using manual labor or inefficient mechanical tools. Traditional methods have the following problems: manual cleaning is inefficient and cannot guarantee consistency; conventional mechanical tools are difficult to adapt to complex flow channel structures; and residual sand particles can easily damage the flow channel surface, affecting aerodynamic performance.

[0021] This application discloses a tool for removing residual sand from the flow channels of a compressor housing. (Refer to...) Figure 1 , Figure 2 and Figure 3The tool for removing residual sand from the compressor housing includes a propulsion head 1, which can enter the interior of the compressor housing's flow channel. One end of the propulsion head 1 is equipped with a grinding component 2, and the other end is connected to a spring seat 3. A linear spring 31 and a corrugated metal hose 32 are connected to the spring seat 3. The corrugated metal hose 32 is sleeved on the outside of the linear spring 31. The lengths of both the linear spring 31 and the corrugated metal hose 32 can cover the length of the compressor housing's flow channel. A suction port 11 is provided on the propulsion head 1, and a negative pressure nozzle 12 is connected to the suction port 11. The negative pressure nozzle 12 is located near the port of the suction port 11 close to the corrugated metal hose 32. The negative pressure nozzle 12 can be connected to a vacuum cleaner via the hose.

[0022] By adopting a composite structure of linear spring 31 and metal corrugated hose 32, it combines flexibility and rigidity, and can bend and deform freely according to the curvature of the flow channel, accurately fitting the inner wall of the narrow flow channel, breaking through the limitations of traditional tools in adapting to complex geometric structures.

[0023] The negative pressure nozzle 12, in conjunction with an external vacuum cleaner, forms an instant vacuuming system that simultaneously removes sand particles generated during polishing, preventing secondary residue.

[0024] The grinding assembly 2 includes a rotating motor 21, a brush roller 22, coarse grinding bristles 23, and fine grinding bristles 24. The rotating motor 21 is mounted on the push head 1. The roller shaft of the brush roller 22 is coaxially connected to the output shaft of the rotating motor 21 via a coupling. Both the coarse grinding bristles 23 and the fine grinding bristles 24 are arranged on the roller surface of the brush roller 22. The coarse grinding bristles 23 are located in the front half of the brush roller 22 away from the rotating motor 21, and the fine grinding bristles 24 are located in the rear half of the brush roller 22 near the rotating motor 21. By arranging the coarse grinding bristles 23 and the fine grinding bristles 24 at the front and rear ends of the brush roller 22, the coarse grinding bristles 23 and the fine grinding bristles 24 can perform staged processing on the inner wall of the compressor housing flow channel during grinding, realizing the automated staged removal of residual sand and burrs, significantly improving work efficiency, reducing manual rework, and ensuring cleaning consistency through standardized mechanical operation.

[0027] The propulsion head 1 has lubricant micro-holes 15, which are located on the side wall of the propulsion head 1. Several lubricant micro-holes 15 are evenly distributed along the circumference of the propulsion head 1. The lubricant micro-holes 15 are filled with lubricant and release lubricant evenly, reducing friction between the brush and the flow channel. Combined with the rounded corner design, it further prevents surface scratches and ensures the integrity of aerodynamic performance.

[0028] A miniature camera 16 is connected to the propulsion head 1. The miniature camera 16 is located on the forward-moving end face of the propulsion head 1. The miniature camera 16 provides real-time internal image feedback to external monitoring equipment to achieve precise positioning and process monitoring.

[0029] The propulsion head 1 is provided with rounded corners at both ends. This design prevents the sharp ends of the propulsion head 1 from contacting the inner wall of the compressor housing flow channel and damaging the flow channel.

[0030] The implementation principle of a tool for removing residual sand from the flow channel of a compressor housing according to an embodiment of this application is as follows: During operation, the operator inserts the push head 1 into the flow channel of the compressor housing, and then starts the rotating motor 21. The rotating motor 21 drives the brush roller 22, coarse grinding bristles 23 and fine grinding bristles 24 to rotate. The coarse grinding bristles 23 and fine grinding bristles 24 are used to perform step-by-step treatment on the inner wall of the flow channel of the compressor housing, so as to realize the automated step-by-step removal of residual sand and burrs. At the same time, the metal corrugated hose 32 is manually pushed into the flow channel of the compressor housing. During this process, the miniature camera 16 can provide real-time internal image feedback to the external monitoring equipment for the operator to observe the internal grinding situation.
