Abstract
The utility model discloses a lathe tapping device. The lathe tapping device aims to overcome problems that in the prior art, the tapping device fails to eliminate a synchronization error caused by main shaft rotation and drag plate feeding to lead to a sleave or a tap fracture. The device comprises a knife pouch, a tap chuck, a tap, a T-shaped pull bar and an elastic component. In the actual operation, due to the synchronization error caused by main shaft rotation and drag plate feeding, the tap is influenced by a rotating force of a workpiece to push the tap chuck to axially move along the knife pouch. The tap chuck is fixedly connected to the T-shaped pull bar. When the tap chuck is driven by a force to move rightward, the T-shaped pull bar moves rightward as well, and the elastic component is compacted. Otherwise, the elastic component is in a loosening state. The elastic component can eliminate the synchronization error caused by main shaft rotation and drag plate feeding, helps to achieve high tapping quality of the workpiece and has no tap fracture.
