Cutter rest for lathe with polishing function

Abstract

The invention relates to a cutter rest for a lathe with a polishing function. The cutter rest comprises a sliding plate, a jacking and pressing block and a jacking and pressing assembly, wherein the sliding plate is used for installing a cutter tool, a long strip-shaped groove is formed in the sliding plate, the jacking and pressing block is connected onto the sliding plate in a sleeving way, the jacking and pressing assembly is fixedly arranged at one side, opposite to the long strip-shaped groove, of the sliding plate, the jacking and pressing assembly comprises a fixing ring and a pushing ring, the fixing ring is fixed with the sliding plate, the pushing ring is movably connected with the fixing ring through a plurality of screw rod assemblies, the cutter tool is vertically arranged into the long strip-shaped groove relative to the sliding plate, one side surface of the cutter tool is tightly pressed on one side of the long strip-shaped groove, the pushing ring moves through regulating the screw rod assemblies, and the jacking and pressing block is tightly pressed onto the other side surface of the cutter tool; a polishing grinding wheel is connected onto the jacking and pressing block in a sleeving way, and the polishing grinding wheel and the jacking and pressing block are rotationally connected; and a motor is also arranged on the sliding plate, and drives the polishing grinding wheel to rotate through a transmission assembly.

Description

technical field [0001] The invention relates to a tool holder for a lathe with a polishing function, which belongs to the field of lathes. Background technique [0002] Generally, after boring a workpiece with a round hole, in order to improve the installation accuracy and aesthetics, it is often necessary to polish the inner wall of the hole, and these tasks are generally to re-clamp the workpiece to some special polishing machine for polishing. However, there are many problems in this polishing method; [0003] 1. When the workpiece is removed from the lathe and re-clamped on the polishing machine, it is difficult to ensure the coaxiality of the two installations because of the second installation. If it is a preliminary polishing, the surface of the polishing head is relatively rough , will bring a certain degree of wear to the inner wall of the hole, and non-coaxial wear will affect the accuracy of the hole. [0004] 2. Re-clamping will bring about a large waste of tim...
