Laser Heating Assisted Micro-turning Device

Abstract

The invention relates to a laser heating auxiliary micro-turning fixture and a laser heating auxiliary micro-turning method and belongs to the field of auxiliary processing of machine tools, and the device and the method are used for solving the problems of poor processed surface quality, tool abrasion and tool breakage existing in the prior art. The device comprises a rotary sliding table, a translation sliding table, a laser and a clamp, wherein the translation sliding table is fixedly arranged on a Y-directional sliding table; the rotary sliding table is fixedly arranged on the translation sliding table; the laser is fixedly arranged on the rotary sliding table by virtue of the clamp; the axis of a gun head of the laser and a vertical surface in which the tool tip of a tool of a machine tool is located are coplanar. According to the method, rays of the laser are applied to the front end of a micro tool tip, and local preheating for a to-be-processed workpiece by virtue of lasers is realized. The laser and the micro-turning device are combined for preheating the to-be-processed workpiece, so that the micro-turning for a difficult-to-process material is realized, the quality and size precision of a processed surface are ensured, the cutting force is reduced, and phenomena of serious tool abrasion and tool breakage substantial results are improved; a camera is used for monitoring in real time, so that the precise and reliable micro diameter of a laser spot can be ensured.
