Quantitative control dressing device special for edge grinding wheel

Abstract

The invention provides a quantitative control dressing device special for an edge grinding wheel. The quantitative control dressing device special for the edge grinding wheel is installed and fixed based on a lathe and comprises a rapid movement mechanism, a feeding mechanism and an abutting mechanism. The rapid movement mechanism vertically moves through a self-locking linear sliding platform. The feeding mechanism comprises a guide sleeve, a guide pipe and flaky oilstone, wherein a through hole where the guide pipe is inserted and a narrow groove where the flaky oilstone can be inserted are formed in the guide sleeve, the guide pipe is located above the flaky oilstone, a counterweight is arranged at the top end of the guide pipe, a plurality of positioning holes are arranged in the axial direction of the guide pipe at equal intervals, and positioning rods are inserted into the positioning holes; a positioning block at the left end of the bottom of the guide sleeve adjoins the left side surface of the flaky oilstone; a pressing wheel arranged in the abutting mechanism abuts against the right side surface of the flaky oilstone. The quantitative control dressing device special for the edge grinding wheel can achieve centering of the flaky oilstone and a V-shaped groove, guarantee accurate positioning of the flaky oilstone, and achieve fixed-stroke and constant-pressure type grinding, thereby quantitatively controlling the dressing process and improving the consistency of the micro forms of work surfaces of the edge grinding wheel and the V-shaped groove.

Description

technical field [0001] The invention belongs to the field of sharpening of superhard material edging grinding wheels, and in particular relates to a special quantitative control sharpening device for edging grinding wheels. Background technique [0002] Superhard material edging wheels are mainly made of superhard materials such as diamond and cubic boron nitride as raw materials. Among them, the edge grinding wheel is mainly used for edge grinding of optical glass, such as figure 1 As shown, several V-shaped grooves are distributed along the axial direction on its outer peripheral surface. The V-shaped grooves are the working surface of the edging grinding wheel, and the shape and size of each V-shaped groove on the same edging grinding wheel are consistent. [0003] However, in the actual use of the edging wheel, the working conditions of each V-shaped groove are quite different, mainly reflected in: (1) After each V-shaped groove processes the workpiece, the quality of t...

AI Technical Summary

Problems solved by technology

Manual operation can only control the total consumption of the whetstone or the sharpening time, but it cannot stably control the relative position of the whetstone and the V-shaped groove and the grinding pressure. The sharpening effect of the V-groove is also unstable, so that the surface micro-morphology of each V-groove cannot be guaranteed to be consistent
