Abstract

The invention discloses a main shaft taper hole grinder. The lower seat is fixed on the working surface of the machine tool. The lower seat is connected upwardly by rolling two sets of rolling linear guide rail pairs to the upper sliding seat. A wire is additionally arranged between the upper sliding seat and the lower seat. Rod transmission mechanism; the upper surface of the upper sliding seat is equipped with a main shaft shell, and the bearings at both ends of the through hole on the upper part of the main shaft shell are set together with the main shaft. There is a main shaft pulley, and the motor pulley is connected to the main shaft pulley; the second bearing at the rear end of the lower seat is equipped with a screw, and the end of the screw is fixed with a hand wheel; the lower surface of the upper sliding seat is connected to an upper slide. The seat screw nut, the external thread on the circumferential surface of the lead screw is matched with the internal thread of the upper slide seat nut. The invention also discloses an online repair method for the taper hole of the main shaft. The device and method of the invention have simple structure and reliable operation.
