Abstract

The invention provides a self-tightening type centering drive plate. The self-tightening type centering drive plate comprises a Morse cone, wherein a drive plate apex is arranged in the Morse cone; the drive plate apex is fixedly connected through an adjusting screw, a top tension spring and compression screws; the drive plate apex is connected to a floating block through a pin; the Morse cone is connected with a lever pressing plate through another adjusting screw, another spring and another pin; the contact of the lever pressing plate is in sliding contact with the floating block; the lever pressing plate is fixedly connected with a pressing head through a screw thread; and the drive plate apex precisely matches the Morse cone, and the fit clearance is 0.005-0.01 mm. The self-tightening type centering drive plate, disclosed by the invention, has the advantages of operation convenience, high precision, low labor intensity and high working efficiency; and the longitudinal separation of a tail seat is only necessary to adjust when work-pieces with different lengths are machined.

Description

technical field [0001] The invention belongs to the mechanical field, in particular to a self-tightening centering dial. Background technique [0002] When turning workpieces with lathes, there is no special tooling. Generally, the following methods are used: use a clamp to cover the outer surface of the workpiece to be processed, and the clamp has a tightening screw to tighten on the outer surface of the workpiece. The force makes the workpiece and the clamp connect as a whole. The workpiece is mounted on the top of the machine tool bed and tailstock. The jacking screw is moved by the lever at the top of the bed, so that the workpiece is rotated and processed. When loading and unloading, each workpiece All will be tightened or loosened with screws one by one, so the operation is labor-intensive, and the precision is poor, and the production efficiency is low. Contents of the invention [0003] The invention provides a self-tightening centering dial, which solves the disa...
