[0044] Working principle: When the equipment is needed, the workpiece to be trimmed and polished is placed inside the housing 1. By holding the workpiece, the cylinder 7 is activated, which drives the moving frame 8 to move. The movement of the moving frame 8 drives the rotating plate 9 to rotate, which in turn drives the positioning clamp 10 to rotate on the inner wall of the support block 11. The rotation of the positioning clamp 10 clamps and fixes the workpiece. Before clamping, the slider 5 can be moved by activating the electric slide rail 4. The movement of the slider 5 controls the movement of the support column 6, thereby adjusting the position of one clamp to accommodate different workpiece lengths. Finally, during the polishing and trimming process, the motor 2 is activated, which drives the housing 3 to rotate, causing one clamp to rotate. The clamped workpiece is then transferred to the other clamp, thus achieving the flipping of the workpiece.

[0045] By starting motor 12, the threaded rod 13 can be rotated. The rotation of the threaded rod 13 can drive the threaded block 14 to move. The movement of the threaded block 14 can cause the electric slide rail 15 to move. The electric slide rail 15 then controls the slider 16 to move, so that the hydraulic cylinder 17 can drive the grinder 18 to be adjusted flexibly. Finally, by starting the hydraulic cylinder 17, the grinder 18 is driven to perform edge trimming and grinding operations on the workpiece.

[0046] Finally, the rotation of the threaded rod 13 drives the drive wheel 20 to rotate. At this time, the drive wheel 20 drives the belt 21 to make the driven wheel 22 rotate. The rotation of the driven wheel 22 drives the extension plate 23 to push the connecting rod 24 to rotate. The rotation of the connecting rod 24 drives the moving block 25 to control the cleaning plate 26 to move on the inner wall of the housing 1, so that the impurities generated during the trimming and polishing operation will be swept and pushed to the front end of the housing 1 to discharge the impurities.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
