The aim of the utility model is realized by the following technical scheme: the on-line repair device for the taper hole precision of the main shaft of the machining center comprises a support frame, wherein an inner longitudinal platform is arranged on the support frame, the inner longitudinal platform is connected with an outer longitudinal sliding table through a sliding power source, a rotating shaft rotating power source is arranged on the outer longitudinal sliding table, a cutter bar is arranged on a rotating shaft of the rotating shaft rotating power source through a chuck, a grinding wheel is arranged on the cutter bar, and the sliding power source and the rotating shaft rotating power source are respectively electrically connected with a microcomputer controller and are uniformly regulated and controlled by the microcomputer controller.

Taper adjusting rods are arranged on the butt joint positions of the two sides of the support frame and the side edges of the inner longitudinal platform, a rotary positioning pin and a taper adjusting groove are arranged on the support frame and the butt joint positions of the support frame and the inner longitudinal platform, and a positioning groove corresponding to the rotary positioning pin and a protrusion corresponding to the taper adjusting groove are arranged on the inner longitudinal platform.

The beneficial effects brought by adopting the technical scheme are as follows: the rotary shaft of the external longitudinal sliding table and the rotary shaft rotary power source is driven to move up and down through the sliding power source, so that the cutter bar and the grinding wheel also do reciprocating up and down rectilinear motion, and the cutter bar and the grinding wheel are driven to rotate at a high speed and reversely rotate the main shaft of the machining center through the rotary shaft, and the grinding wheel penetrates into the conical hole of the main shaft of the machining center to grind and repair the conical hole on line. And the inner longitudinal platform is properly adjusted in swinging angle through the taper adjusting rod on the supporting frame, so that the grinding angle of the main shaft taper hole of the machining center can be adjusted in advance, and the main shaft taper hole of the machining center can be automatically repaired within one or two hours without waiting for a long time. The device has high working efficiency and high repair precision, and reduces the working labor intensity.
