A fixing plate 10 is fixedly mounted on the top of the mounting vertical plate 9. A polishing assembly is mounted on the top of the fixing plate 10. A rotating stage 19 is overlapped on the top of the mounting frame 1. A rotating shaft 20 is fixedly mounted on the bottom of the rotating stage 19. The number of rotating stages 19 and rotating shafts 20 are both several. The rotary table 19 and several rotary axes 20 are arranged in a linear array, allowing multiple tubular parts 26 to be placed simultaneously. During polishing of the tubular parts 26, tubular parts 26 in other positions can be replaced. The rotary axes 20 are rotatably mounted inside the mounting bracket 1. A clamping assembly is provided on the top of the rotary axis 20, and the tubular parts 26 are held on the top of the rotary axis 20 via the clamping assembly. The polishing assembly includes a rectangular plate fixedly mounted on the top of the fixed plate 10. A drive motor 11 is fixedly mounted on the front side of the rectangular plate, and a circular hole is provided through the front side of the rectangular plate. The radius of the output end of the drive motor 11 is smaller than the radius of the circular hole. A rotating shaft 12 is fixedly installed at the output end. A connecting groove 13 is formed on the surface of the rotating shaft 12. A rotating sleeve 14 is slidably installed inside the connecting groove 13. A limiting plate 15 is rotatably installed on the surface of the rotating sleeve 14. The limiting plate 15 is fixedly installed on the top of the fixed plate 10 on the rear side. A driving bevel gear 16 is fixedly installed on the front side of the rotating sleeve 14 and the front end of the rotating shaft 12.

There are two polishing rollers 18, and the two polishing rollers 18 are symmetrically distributed. Through the arrangement of the two polishing rollers 18, the tubular part 26 is polished. The two polishing rollers 18, rotating at the same speed but in opposite directions, can drive the tubular part 26 to rotate, thereby polishing the tubular part 26 thoroughly. The polishing rollers 18 are rotatably set inside the fixed plate 10. The drive motor 11 drives the output end to drive the rotating shaft 12 to rotate. The rotating shaft 12 drives the rotating sleeve 14 to rotate through the connecting groove 13, so that the rotating sleeve 14 and the rotating shaft 12 simultaneously drive the active bevel gear 16 to rotate, so that the driven bevel gear 17 drives the polishing rollers 18 to polish the tubular part 26. At the same time, the two polishing rollers 18 rotating at the same speed but in opposite directions will drive the tubular part 26 to rotate, thereby enabling the tubular part 26 to be polished thoroughly.

[0023] Specifically, the front and rear adjustment assembly includes a servo motor 4 fixedly installed on the front side of the U-shaped frame 3. A rotating screw 5 is fixedly installed at the output end of the servo motor 4. An adjusting sleeve 6 is threaded onto the surface of the rotating screw 5.

A slide rail 8 is slidably installed inside the sliding sleeve 7. The slide rail 8 is fixedly installed on the lower side wall of the U-shaped frame 3. When it is necessary to grind tubular parts 26 of different specifications, the servo motor 4 drives the rotating screw 5 to rotate, causing the adjusting sleeve 6 to move the sliding sleeve 7 on the surface of the slide rail 8. This causes the adjusting sleeve 6 to move the mounting plate 9, and the mounting plate 9 moves accordingly. Plate 9 drives the fixed plate 10 to move. The front fixed plate 10 drives the drive motor 11 to move forward through the rectangular plate, so that the rotating shaft 12 drives the front active bevel gear 16 to move forward, and drives the front driven bevel gear 17 to move forward through the front polishing roller 18. The rear fixed plate 10 drives the rotating sleeve 14 to move backward through the limiting plate 15, and drives the rear active bevel gear 16 to move backward. The rear fixed plate 10 drives the rear driven bevel gear 17 to move through the rear polishing roller 18, thereby adjusting the distance between the two polishing rollers 18, so that tubular parts 26 with different diameters can be polished.

[0024] Specifically, the clamping assembly includes a mounting block 21 fixedly mounted on the top of the rotary table 19. A connecting screw 22 is rotatably mounted inside the mounting block 21.

A clamping plate 24 is mounted on the end of the upper flip plate 23 via a hinge seat. The inside of the tubular part 26 is in contact with the clamping plate 24. A lower flip plate 25 is mounted on the surface of the clamping plate 24 via a hinge seat. The lower flip plate 25 is connected to the mounting block 21 via a hinge seat. Rotating the connecting screw 22 causes the movable sleeve 27 to push the clamping plate 24 through the hinge seat and the upper flip plate 23 to fix the position of the tubular part 26, thereby facilitating the positioning of the tubular part 26 and preventing the tubular part 26 from falling off during the polishing process.

[0025] The polishing equipment for aerospace parts is connected to 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0026] In use: Place the tubular part 26 to be polished on top of the rotating shaft 20. Rotate the connecting screw 22, causing the moving screw sleeve 27 to rotate the upper flip plate 23 via the hinge seat. The upper flip plate 23 pushes the clamping plate 24 to move via the hinge seat. The connecting screw 22 rotates the lower flip plate 25 via the hinge seat, causing the clamping plate 24 to contact the inner wall of the tubular part 26, fixing the position of the tubular part 26. The electric linear guide 2 drives the moving seat to move the U-shaped frame 3, causing the U-shaped frame 3 to move via the rotating screw 5, which in turn moves the adjusting screw sleeve 6, and the adjusting screw sleeve 6 moves the mounting vertical plate 9. The mounting plate 9 drives the polishing roller 18 to move, so that the middle part of the polishing roller 18 is horizontally aligned with the middle part of the tubular part 26. The drive motor 11 drives the output end to drive the rotating shaft 12 to rotate. The rotating shaft 12 drives the rotating sleeve 14 to rotate through the connecting groove 13. The rotating sleeve 14 and the rotating shaft 12 simultaneously drive the driving bevel gear 16 to rotate, which in turn drives the driven bevel gear 17 to rotate. The two driven bevel gears 17 rotate in opposite directions at the same speed, and the driven bevel gear 17 drives the polishing roller 18 to polish the tubular part 26. At the same time, the polishing roller 18 pushes the tubular part 26 to rotate.
