[0038] In the utility model, the supporting mechanism includes a plurality of mounting seats 8 fixedly arranged on the top of the workbench 1, a guide seat 9 is inserted on the top of the mounting seat 8, the steering shaft is located between the two rollers on the guide seat 9, a first bolt 10 is provided through a thread on one side of the mounting seat 8, one end of the first bolt 10 is in contact with the guide seat 9 and is used to fix the guide seat 9.

[0043] When in use, the transmission shaft is placed on a plurality of guide seats 9, and the electric push rod 14 is started to drive the support plate 2 on one side to move. The movement of the support plate 2 can drive the top 3 to contact the transmission shaft until the two tops 3 clamp the transmission shaft. At this time, the rotating shaft 21 conflicts with the reciprocating screw 13, and the polishing machine 6 and the motor 4 are started. The rotation of the motor 4 can drive the top 3 to rotate, and drive the transmission shaft to rotate. At the same time, it can drive the rotating shaft 21 to rotate through the synchronous wheel 22 and the synchronous belt 23. The rotation of the rotating shaft 21 can drive the reciprocating screw 13 to rotate through the friction between the rotating shaft 21 and the reciprocating screw 13. The rotation of the reciprocating screw 13 can drive the sliding seat 5 to move. The movement of the sliding seat 5 can drive the polishing machine 6 to move. When the wedge block 20 contacts the transition portion 16, it will drive the wedge block 20 to move downward through the guide strip 7, so that the polishing machine 6 contacts the transmission shaft and grinds the transmission shaft, so that it grinds the transmission shaft while moving.

[0044] When a larger transmission shaft needs to be polished, the first bolt 10 is rotated to move one end of the first bolt 10 away from the guide seat 9. At this time, the guide seat 9 can move the rod up and down to adjust the support height, and the guide bar 7 can be removed from the multiple support bars 11, and the corresponding guide bar 7 can be replaced to continue processing and polishing.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
