[0030] The polishing mechanism 2 includes a motor 21 and a polishing roller 22 . The motor 21 is mounted on the base plate 1 , and the polishing roller 22 is mounted on the output shaft end of the motor 21 .

[0031] The fixing mechanism 3 includes an electric slide rail 31, a clamping assembly 32 and a fixing assembly 33. The electric slide rail 31 is installed on the base plate 1. A movable slider is installed on the electric slide rail 31 along the axial direction of the polishing roller 22. The clamping assembly 32 includes a lower jacket 321, an upper jacket 322 and a locking structure. The lower jacket 321 is located on the lower side of the polishing roller 22 and one end of it is connected to the slider and the other end is rotatably connected to the upper jacket 322. The upper jacket 322 is located on the upper side of the polishing roller 22 and its distal end can be rotatably engaged with the end of the lower jacket 321 close to the slider so that the polishing roller 22 is located between the lower jacket 321 and the upper jacket 322. The locking structure is used to lock the engaged lower jacket 321 and the upper jacket 322. The fixing assembly 33 is used to fix the bushing to the inner side of the lower jacket 321 and the upper jacket 322.

[0032] The bushing to be processed is placed on the polishing roller 22, the bushing is clamped by the clamping assembly 32, and the opening on the bushing is fixed by the fixing assembly 33. The position of the clamping assembly 32 on the polishing roller 22 is adjusted by the slider on the electric slide rail 31, and the motor 21 is started to enable the polishing roller 22 to polish the inner wall of the bushing.

[0033] The locking structure includes an installation groove 323, an avoidance groove 324 and a threaded rod 326. The installation groove 323 is opened at one end of the lower jacket 321 close to the slider, and the avoidance groove 324 is opened at the far end of the upper jacket 322. One end of the threaded rod 326 is rotatably installed in the installation groove 323 through the rotating shaft 325. A locking nut 327 is screwed on the threaded rod 326, and the outer diameter of the locking nut 327 is larger than the width of the avoidance groove 324.

[0034] The fixing assembly 33 includes a through hole 331, a threaded sleeve 332 and a first bolt 333. A through hole 331 is opened on the side wall of the lower jacket 321 and the upper jacket 322 respectively. A threaded sleeve 332 is arranged in the through hole 331. The first bolt 333 is threadedly screwed into the threaded sleeve 332. The first bolt 333 can be screwed into the opening in the side wall of the bushing.

[0035] Preferably, a guide sleeve 336 is provided on the inner wall of the through hole 331, and the inner ring diameter of the guide sleeve 336 tends to expand in the direction close to the polishing roller 22. The first bolt 333 is rotatably connected to both sides of one end close to the polishing roller 22 with locking rods 334, and a spring 337 is connected between the two locking rods 334. The two locking rods 334 are further provided with guide blocks 335 on the side away from each other that abut against the inner wall of the guide sleeve 336.

[0036] When the present invention is used, the bushing is placed on the lower sleeve 321, and the through hole 331 on the lower sleeve 321 is aligned with an opening of the bushing, and the first bolt 333 is rotated. The first bolt 333 drives the two locking rods 334 to move, and the locking rods 334 drive the guide block 335 to slide in the inner wall of the guide sleeve 336. The position of the guide block 335 changes with the inner wall size of the guide sleeve 336 during the sliding process. The two locking rods 334 rotate around the first bolt 333 under the action of the spring 337. When the two locking rods 334 move into the opening of the bushing, the two locking rods 334 contact the inner wall of the bushing, thereby locking an opening of the bushing. Then close the upper jacket 322, rotate the threaded rod 326 into the avoidance groove 324, rotate the locking nut 327 to clamp the lower jacket 321 and the upper jacket 322, then rotate the first bolt 333 opened on the upper jacket 322, and repeat the above principle to lock the other opening of the bushing. The two locking rods 334 can lock openings of different sizes.

[0037] Furthermore, the chamfering mechanism 4 is further included. The chamfering mechanism 4 includes a chamfering tool 41 and a tool groove 42. The tool groove 42 is provided at the distal end of the polishing roller 22. The chamfering tool 41 is provided with a second bolt 43, which is threadedly connected to the bottom of the tool groove 42. The slider on the electric slide 31 drives the clamping assembly 32 to adjust the bushing to the turning position of the chamfering mechanism 4 to chamfer one end of the chamfering mechanism 4.

[0038] When the utility model is used, the motor 21 is started, the motor 21 drives the polishing roller 22 to rotate, the polishing roller 22 drives the chamfering tool 41 to rotate, and the slider on the electric slide rail 31 adjusts the position of the bushing so that the polishing roller 22 polishes the inner end of the bushing, and at the same time the chamfering tool 41 chamfers the edge of the bushing.
