Description

Technical Field

[0001] This utility model relates to the field of compressor housing processing equipment technology, and in particular to a cleaning device for a compressor housing machining center. Background Technology

[0002] A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It utilizes the inertial force of the exhaust gases from the engine to drive a turbine within the turbine housing. The turbine, in turn, drives a coaxial impeller, which compresses the air supplied through the air filter and forces it into the cylinders. As engine speed increases, the exhaust gas velocity and turbine speed also increase simultaneously, causing the impeller to compress even more air into the cylinders. The increased air pressure and density allow for the combustion of more fuel. By increasing the fuel quantity and adjusting the engine speed, the engine's output power can be increased. To accommodate the internal structure of the turbocharger, the turbocharger housing often needs to be machined in a specialized workshop to have a curved surface and a certain degree of openwork in the center. This machining process often generates debris, which needs to be cleaned promptly to prevent debris adhering to the housing from entering the turbocharger and affecting its operation.

[0003] Traditional cleaning methods use manual air guns to blow away debris, which suffers from low efficiency, incomplete cleaning of blind spots, and secondary splashing of debris. Utility Model Content

[0004] To address the issues of low efficiency, incomplete cleaning of blind spots, and secondary debris splashing associated with manual air gun cleaning, this application provides a cleaning device for a machining center used for compressor housings.

[0005] The cleaning device for a compressor housing machining center provided in this application adopts the following technical solution:

[0006] A cleaning device for a compressor housing machining center includes a base with a clamping assembly for holding and fixing the compressor housing. The base also has uprights with one upright at each end of the clamping assembly, the two uprights being parallel to each other. A lifting plate is positioned between the two uprights, and a driving assembly for moving the lifting plate up and down is mounted on the uprights. A rotating head with a nylon brush is positioned below the lifting plate. A rotating assembly for driving the rotating head to rotate circumferentially within the compressor housing is mounted on the lifting plate. A fixing pipe is connected to the lifting plate, perpendicular to the lifting plate. A protective cover is connected to the fixing pipe, covering the rotating head and also covering the compressor housing. A negative pressure suction nozzle is connected to the protective cover, vertically positioned, and several nozzles are evenly distributed circumferentially around the protective cover. A vacuuming device is connected to each negative pressure suction nozzle via a flexible hose.

[0007] Preferably, the clamping assembly includes a push cylinder and a clamping plate. The push cylinder is mounted on the base, and two push cylinders are provided on the base and are arranged opposite to each other. The clamping plate is connected to the end of the piston rod of the push cylinder and is an arc-shaped plate adapted to the side wall of the compressor housing.

[0008] Preferably, the base is connected to a positioning post that can pass through the central hole of the compressor housing. The positioning post is arranged in a direction perpendicular to the base. The side wall of the positioning post slides against the inner wall of the central hole of the compressor housing. The positioning post is located between two clamping plates.

[0009] Preferably, the driving assembly includes a fixed plate, a lifting cylinder, and a slider. The slider is connected to the lifting plate and has one slider on each of the opposite sides of the lifting plate. A through groove for the slider to slide is provided on the vertical plate. The through groove passes through the top of the vertical plate and two opposite side walls. The fixed plate is connected to the top of the vertical plate. The lifting cylinder is connected to the fixed plate and is arranged vertically. The piston rod of the lifting cylinder passes through the fixed plate and is connected to the slider.

[0010] Preferably, the rotating assembly includes a rotating motor, a fixed bearing, and a rotating rod. The fixed bearing is connected to the lifting plate, and the axis of the fixed bearing is collinear with the axis of the fixed tube. One end of the rotating rod passes through the fixed tube and is connected to the fixed bearing, while the other end is connected to the rotating head. The bottom of the rotating rod connected to the rotating head is stepped. The rotating motor is mounted on the lifting plate, and the output shaft of the rotating motor is coaxially connected to the rotating rod via a coupling.

[0011] Preferably, a sealed bearing is connected inside the fixed tube, the sealed bearing is located at the bottom of the fixed tube, and the rotating rod is connected to the sealed bearing.

[0012] Preferably, the base has a connection hole for connecting to a machining center.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This utility model provides a cleaning device for a compressor housing machining center. A lifting plate drives the nylon brush to move up and down, and a rotating assembly drives it to rotate circumferentially inside the compressor housing. This achieves full-coverage cleaning of the curved surfaces and hollow structures of the compressor housing, significantly improving cleaning efficiency. Through a protective cover and several negative pressure nozzles, debris is collected in real time during cleaning, forming an integrated "cleaning-vacuuming" process. This improves the situation of secondary debris splashing, thus addressing the problems of low efficiency, incomplete cleaning of dead corners, and secondary debris splashing associated with manual air gun cleaning.

A negative pressure suction nozzle 312 is connected to the protective cover 311. The negative pressure suction nozzle 312 is arranged vertically. Several negative pressure suction nozzles 312 are evenly distributed around the circumference of the protective cover 311. A dust collection device is connected to the negative pressure suction nozzle 312 through a flexible hose.

[0021] The lifting plate 3 drives the nylon brush 51 to move up and down, and the rotating component 6 drives it to rotate circumferentially inside the compressor housing, achieving full coverage cleaning of the curved surface and hollow structure of the compressor housing, significantly improving cleaning efficiency. Through the protective cover 311 and several negative pressure suction nozzles 312, debris is collected in real time while cleaning, forming an integrated "sweeping-vacuuming" process, improving the situation of secondary debris splashing.

[0022] The clamping assembly 2 includes a push cylinder 21 and a clamping plate 22. The push cylinder 21 is mounted on the base 1. There are two push cylinders 21 on the base 1, and the two push cylinders 21 are arranged opposite to each other.

[0023] A positioning post 13 is connected to the base 1, which can be inserted into the center hole of the compressor housing. The positioning post 13 is set in a direction perpendicular to the base 1. The side wall of the positioning post 13 slides against the inner wall of the center hole of the compressor housing. The positioning post 13 is located between two clamping plates 22.

[0024] By setting the positioning post 13, the position of the compressor housing on the base 1 can be quickly positioned. At the same time, the positioning post 13 can seal the shaft hole of the compressor housing to prevent debris from remaining in the shaft hole.

[0025] The drive assembly 4 includes a fixed plate 41, a lifting cylinder 42, and a slider 43. The slider 43 is connected to the lifting plate 3. The slider 43 is provided on opposite sides of the lifting plate 3. A through groove is provided on the vertical plate 12 for the slider 43 to slide. The through groove passes through the top of the vertical plate 12 and two opposite side walls. The fixed plate 41 is connected to the top of the vertical plate 12. The lifting cylinder 42 is connected to the fixed plate 41. The lifting cylinder 42 is arranged in a vertical direction. The piston rod of the lifting cylinder 42 passes through the fixed plate 41 and is connected to the slider 43.

[0027] A sealed bearing 313 is connected inside the fixed tube 31. The sealed bearing 313 is located at the bottom of the fixed tube 31. The rotating rod 63 is connected to the sealed bearing 313. The sealed bearing 313 prevents debris from entering the rotating parts, extends the service life of the device, and, together with the fixed bearing 62, limits both ends of the rotating rod 63, which helps to improve the stability of the rotating rod 63 during rotation.

[0028] The base 1 has a connection hole 11 for connecting to the machining center, which facilitates the connection of the cleaning device to the machining center.

[0029] The implementation principle of the cleaning device for a compressor housing using a machining center according to an embodiment of this application is as follows: During operation, the robotic arm of the machining center places the compressor on the base 1 and sleeves it on the outside of the positioning column 13. Then, the push cylinder 21 pushes the clamping plate 22 to clamp and fix the compressor housing. Next, the lifting cylinder 42 pushes the slider 43 to drive the lifting plate 3 to descend, so that the rotating head 5 enters the interior of the compressor housing. At this time, the protective cover 311 covers the outside of the compressor housing and forms an enclosing structure with the compressor housing. Then, the rotating motor 61 drives the rotating rod 63 to rotate. The rotating rod 63 drives the rotating head 5 and the nylon brush 51 to rotate along the circumference inside the compressor housing, forming an integrated "cleaning-vacuuming" process in conjunction with the negative pressure suction nozzle 312.
