Detailed Description

As shown in fig. 1 and 2, the invention provides an auxiliary device for processing a rotating shaft, which comprises a sliding seat 9, a thimble assembly 1 arranged on the sliding seat 9, a chuck 2, a fixed disk 3, a movable clamping block 4, a guide disk 5, a motor 6 and a cylinder 7, wherein the chuck 2 is connected with the sliding seat 9 through the fixed disk 3, the movable clamping block 4 is slidably connected with the chuck 2, one end of the guide disk 5 is connected with the motor 6, the other end of the guide disk 5 is rotatably connected with the chuck 2, the movable clamping block 4 is connected with the guide disk 5, the movable clamping block 4 moves inwards or outwards at the same time by taking the axis of the thimble assembly 1 as the center through the guide of the guide disk 5, the cylinder 7 is connected on the fixed disk 3, one end of the thimble assembly 1 is slidably connected with the cylinder 7, and the thimble assembly 1 moves telescopically relative to the guide disk 5 through the action of the cylinder 7.
