[0001] This utility model relates to the field of compressor housing processing equipment technology, and in particular to a pneumatic cleaning machine for compressor housing testing samples. Background Technology

[0002] Compressor: In a gas turbine engine, the component that uses high-speed rotating blades to do work on the air and increase its pressure. The curved front end of the compressor impeller blades is called the guide wheel, which guides the gas into the working impeller without impact, reducing airflow impact loss. During the manufacturing process, the end wall of the compressor housing is polished and precision machined. After machining, dust will accumulate on the end wall of the compressor housing, which needs to be cleaned.

Typically, an air gun is provided on the compressor housing processing table for manual cleaning of the end walls. However, due to the large amount of work involved in compressor housing manufacturing, the conventional manual cleaning method using an air gun is labor-intensive and inefficient, which is not conducive to the mass production of compressor housings.

A track 11 for placing the compressor housing is rotatably connected to the fixed frame 1. A rotating assembly 2 for driving the track 11 is provided on the fixed frame 1. The two ends of the track 11 are respectively the feed end for connecting to the previous station and the discharge end for connecting to the next station. A first fixing plate 12 and a second fixing plate 13 are connected to the fixed frame 1. The first fixing plate 12 and the second fixing plate 13 are located opposite each other on the fixed frame 1. On both sides, an air guide pipe 121 and a high-pressure nozzle 122 are connected to the first fixing plate 12, and a material collection pipe 131 is connected to the second fixing plate 13. The air guide pipe 121 is located between the material collection pipe 131 and the high-pressure nozzle 122. The high-pressure nozzle 122 is arranged in the direction towards the material collection pipe 131. An auxiliary component 3 for connecting the air guide pipe 121 and the material collection pipe 131 is provided on the material collection pipe 131. A dust collection bag 4 is connected to the tail end of the material collection pipe 131. A connecting component 5 for connecting the dust collection bag 4 is provided on the material collection pipe 131.

[0020] Through the coordinated design of the conveyor system 11 and the rotating component 2, the compressor housing is automatically and continuously conveyed. The collecting pipe 131 and the air guide pipe 121 form a closed-loop airflow channel through the auxiliary component 3. Combined with the high-pressure nozzle 122 and the auxiliary component 3, a bidirectional airflow is formed to cover the entire surface of the compressor housing, ensuring that dust is efficiently sucked into the dust collection bag 4. The dust collection bag 4 is connected by the connecting component 5, which enables the quick replacement of the dust collection bag 4 on the collecting pipe 131.

[0021] The rotating assembly 2 includes a pulley 21 and a rotating motor 22. The pulley 21 is connected to the fixed frame 1 and is arranged along the width direction of the fixed frame 1. There is one pulley 21 at each end of the fixed frame 1 along the length direction. The track 11 is tensioned and sleeved between the two pulleys 21. The rotating motor 22 is connected to the fixed frame 1, and the output shaft of the rotating motor 22 is coaxially connected to the wheel axle of one of the pulleys 21 through a coupling.

[0022] The auxiliary component 3 includes a push cylinder 31, a protective plate 32, and a connecting plate 33. The push cylinder 31 is connected to the collecting pipe 131 and is arranged along the length of the collecting pipe 131. The protective plate 32 has an inverted "U" shaped cross section and is slidably arranged above the collecting pipe 131. The connecting plate 33 is fixedly connected to the protective plate 32. The piston rod of the push cylinder 31 is connected to the connecting plate 33. The protective plate 32 can be connected to the air guide pipe 121.

[0023] By pushing the cylinder 31 to push the connecting plate 33 and the protective plate 32, the protective plate 32 is connected to the air guide pipe 121 and the material collection pipe 131 to form a closed-loop airflow channel, which reduces dust and airflow escape and improves energy utilization.

[0024] An auxiliary nozzle 321 is connected to the protective plate 32 for blowing on the end wall of the compressor housing opposite to the air guide duct 121. The auxiliary nozzle 321 is inclined toward the collection pipe 131. A connecting pipe 322 is connected between the air outlet of the protective plate 32 and the auxiliary nozzle 321. When the protective plate 32 is connected to the air guide duct 121 and the collection pipe 131, the auxiliary nozzle 321 can blow on the end wall of the compressor housing opposite to the air guide duct 121, so that the airflow of the high-pressure nozzle 122 and the auxiliary nozzle 321 can fully cover the end wall of the compressor housing, improving cleaning efficiency.

[0025] A mounting bracket 14 is connected to the fixed frame 1. The mounting bracket 14 is located at the discharge end of the fixed frame 1. A displacement sensor 141 for detecting the position of the compressor housing is connected to the mounting bracket 14. The displacement sensor 141 on the mounting bracket 14 can monitor the workpiece position information in real time and form feedback control with the rotating motor 22 to ensure that the compressor housing is accurately parked at the cleaning station and avoid incomplete cleaning due to positioning deviation.

[0026] The connecting component 5 includes a fixed frame 51 and a hoop 52. The fixed frame 51 is connected to the tail end of the collecting pipe 131. The fixed frame 51 is a rectangular frame. The fixed frame 51 has a slot for the hoop 52 to be inserted. The opening of the dust collection bag 4 is fitted onto the fixed frame 51. The slot is set along the circumference of the fixed frame 51. There are two hoops 52. The two hoops 52 can be spliced ​​and wrapped in the slot. The ends of the two hoops 52 are connected by bolts.

[0027] The dust collection bag 4 is connected by a split hoop 52 and can be quickly disassembled and replaced by bolt fastening. Combined with the rectangular fixing frame 51 design, it greatly shortens the downtime for maintenance.

[0028] The implementation principle of a pneumatic cleaning machine for compressor housing inspection samples in this application embodiment is as follows: During cleaning, the compressor housing is placed on the track 11, and the displacement sensor 141 monitors the workpiece position information in real time, forming feedback control with the rotating motor 22 to transport the compressor housing to a precise stop at the cleaning station. Then, the push cylinder 31 pushes the connecting plate 33 and the protective plate 32, so that the protective plate 32 connects with the air guide pipe 121 and the material collection pipe 131 to form a closed-loop airflow channel. Then, the external air supply equipment supplies air to the high-pressure nozzle 122 and the auxiliary nozzle 321. The bidirectional high-pressure airflow blows the dust on the end wall of the compressor housing into the material collection pipe 131 and is collected by the dust collection bag 4.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model.
