A kind of workpiece inner hole polishing equipment for lathe and using method thereof

Abstract

The invention relates to workpiece inner hole polishing equipment for a lathe and a use method of the workpiece inner hole polishing equipment. The workpiece inner hole polishing equipment comprises a connecting base, a polishing grinding wheel and a driving mechanism, wherein the connecting base comprises a clamping block connected with a knife rest, a plurality of screw holes are formed in the clamping block in an array manner, the polishing grinding wheel is fixedly connected with the clamping block through a switching block, and the switching block is fixedly connected with different screw holes, so that the relative position of the polishing grinding wheel and the knife rest is changed; the polishing grinding wheel rotates under the drive of the driving mechanism; a closed annular rack is coaxially arranged on the polishing grinding wheel, a power input shaft is rotationally connected to the switching block, and the power input shaft is driven by a gear meshed with the rack; the driving mechanism comprises a power source connected with the power input shaft; a polishing grinding wheel with power is fixedly mounted with a knife, and the surface of a round workpiece is synchronously polished while turning is performed; the structure is simple, the efficiency is high, and great convenience is provided for later dimension measurement of the surface of a workpiece inner hole.

Description

technical field [0001] The invention relates to a workpiece inner hole polishing device for a lathe and a use method thereof, belonging to the field of lathe expansion devices. 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...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved by the present invention is: to overcome the technical problem that the traditional lathe in the prior art cannot turn and grind the inner hole of the workpiece, and provide a lathe expansion structure and its use method, so that the workpiece can be turned while turning polishing
