Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of severe wear of the grinding wheel when using the array profiling grinding wheel in the grinding process of the cylindrical array structure of the high-order curve section; and the grinding of the single arc grinding wheel requires repeated grinding of the array structure unit. Due to the long processing cycle and high cost of the workpiece, a method for precision grinding of high-order curve cross-section cylindrical array structures using arc array grinding wheels with variable tangency points is proposed

Abstract

The invention discloses a method for grinding a cylindrical array structure with a high-order curve section by an arc array grinding wheel. The grinding wheel is trimmed into an arc array structure with repeated k-order sections, and an array cylindrical surface is ground through the arc array grinding wheel in a variable tangential point reciprocating manner according to the curve tangency principle; and the movement path of the grinding wheel in the high-order curve section plane of the cylindrical surface is an equidistant parallel line at the distance of r from a high-order curve. After the tangential point of the grinding wheel is changed once in the high-order curve section plane, the grinding wheel does reciprocating motion in the direction perpendicular to the high-order curve section plane for one time, so that the grinding of one generating line of the cylindrical surface is finished. Since the grinding wheel is of an array structure, the grinding process of all high-order curve section cylindrical arrays can be finished as long as the grinding of one cylindrical structure unit in the array structure is finished. After the section unit structure of the grinding wheel is trimmed into an arc, the tangential points between the grinding wheel and workpieces are ensured to form the high-order curve through the interpolation motion of a machine tool; and the array structureis ground in a variable tangential point manner, and the grinding accuracy is high.

Description

technical field [0001] The invention relates to a grinding processing method, which uses an arc array grinding wheel to carry out variable tangent point precision grinding on a high-order curve section cylinder array, and only needs to perform one grinding cycle on the array unit to complete the forming grinding of the array structure . Background technique [0002] In industries such as automobiles, electronics, and optics, it is necessary to process a large number of high-order curved cross-section cylindrical array structures, and the requirements for shape accuracy and surface quality are getting higher and higher. At present, the methods for precise grinding of the array structure can be mainly divided into two categories. The first type is to trim the section of the grinding wheel into a shape that matches the array structure, and directly perform profiling grinding on the array structure. The advantage of this method is that the processing efficiency is high, but the...
