Abstract

The invention discloses a laser processing PCD diamond tool sharpening device and method. The sharpening device comprises a laser device light path part and a sample clamping part. The laser device light path part comprises a laser device, a laser device outer light path and a galvanometer which are sequentially connected. The sample clamping part comprises a first positioning support column, a second positioning support column, a control lifting stud, a vertical lifting platform, a sample base and a clamping device shell. The sample base is designed for the size of a specific diamond drill bit, and drill bits different in size can be machined by replacing the sample base. The sample base is positioned above the vertical lifting platform. Through cooperation of the sample base and the vertical lifting platform, the position of a sample is accurately positioned, the vertical lifting platform is connected with the control lifting stud through threads, the control lifting stud is connected with the motor, the motor is used for driving the control lifting stud to rotate, accurate ascending and descending of the vertical lifting platform are achieved, and accordingly, ascending, descending and positioning during machining are achieved.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser processing PCD diamond tool sharpening device and method. Background technique [0002] PCD (Polycrystalline Diamond) is a kind of polycrystalline diamond sintered at high temperature and high pressure (1450-1700°C, 5.5-7.0GPa) by using high-quality diamond (0.5μm~50μm) and adding a certain component of catalyst. polymer. For a long time, PCD has been used in various fields due to its extremely high hardness and excellent wear resistance, especially in the field of cutting tools, which is playing an increasingly important role. PCD can be used not only to produce turning tools and boring tools, but also to produce complex props such as milling cutters, drills, reamers, saws, routers, and punches. In the fields of automobile, aviation and parent material processing, PCD tools have been widely used. The processing materials include non-ferrous metals such as alum...
