Index plate device based on mouse chain wheel meshing

The invention discloses an index plate device based on mouse chain wheel meshing. The device comprises a C-axis adjusting device upper box body, a C-axis adjusting device lower box body, a locking flange plate, a C-axis index adjusting device dial, a fixed mouse chain wheel, a movable mouse chain wheel and a blind rivet. According to the indexing plate device based on the mouse chain wheel meshing, a gap between an upper box body and a lower box body and axial pressure relative to an input shaft of a lathe are adjusted by adjusting clockwise and anticlockwise rotation of a nut installed on the upper box body of the C-axis adjusting device, and therefore meshing, disengaging and fastening actions of a fixed mouse chain wheel and a movable mouse chain wheel are completed. In addition, the fixed mouse chain wheel and the movable mouse chain wheel in the scheme can be replaced with chain wheels with different graduations, such as 1 degree, 2 degrees, 5 degrees and the like according to factory requirements.
