Laser large-cutting-depth trimming device and method for formed grinding wheel

Abstract

The device comprises a truss, a working platform, a grinding wheel, a motor, an X-direction manual sliding table, a Y-direction manual sliding table, a laser vibrating lens, a Z-direction electric sliding table, a super field depth microscope, an A-direction electric sliding table, a controller, a computer and a displayer. Aiming at the defects that a laser quasi-tangential method can be used for shaping but is difficult to sharpen, and a laser radial method can be used for sharpening but is difficult to precisely shape, an effective power density model of a Gaussian laser beam scanning grinding wheel surface is established, and the laser large-cutting-depth trimming method for the formed grinding wheel is provided on the basis. By means of the method, efficient and precise shaping of the surface profile of the grinding wheel can be achieved, and precise control over the surface appearance of the grinding wheel can be achieved. During large-cutting-depth shaping, the grinding wheel material removing efficiency is high, and automation is easy to achieve in the process; and during large-cutting-depth dressing, the bonding agent material removal uniformity is good, and the abrasive particle exposure height controllability is high.

Description

Technical field [0001] The present invention belongs to the field of grinding wheel dressing technology, specifically, relates to a forming grinding wheel laser large cut depth dressing device and method. Background [0002] The forming and grinding process of grinding wheel is an important processing method for complex curved parts (such as gears and turbine blades) that have become increasingly widely used in the aerospace, automotive industry and construction machinery in recent years. For form grinding, the reduction in the profile accuracy of the workpiece caused by grinding wheel wear is the main technical bottleneck that limits its large-scale promotion and application. The key to the grinding of the forming grinding wheel is the industry consensus, due to the complex profile of the forming grinding wheel section, the extremely high hardness of the abrasive particles, and the high holding strength of the binder, resulting in the forming grinding wheel, especially the super...
