A pulley finishing equipment

Abstract

The present invention discloses a pulley finishing turning device, comprising: a machine tool base fixed with a housing; a tool row plate fixed with a finishing turning tool; a machine tool spindle fixed with a three-jaw chuck; a clamping reinforcement mechanism, comprising a push rod member fixedly connected to the inner end of the claw of the three-jaw chuck in a stepped shape, a fixed shaft member movably sleeved in the three-jaw chuck, and an inclined slot matched with the push rod member on the fixed shaft member; a rubber sleeve fixedly sleeved on the fixed shaft member, and a push plate that can form a push against the rubber sleeve is fixedly connected to the front end of the fixed shaft member, and a fixed ring plate is fixedly provided at the rear end of the rubber sleeve; an elastic member is used to form an inward pulling force on the fixed shaft member, so that the rear end face of the fixed ring plate is fixedly abutted against the front end face of the push rod member. The present invention can effectively form a stable clamping of the pulley workpiece and reduce the adverse effects on the running stability of the machine tool spindle.
