A Throat Plane Positioning Method Based on Surface Features of Toroidal Worm

Abstract

The invention belongs to the technical field of precision measurement, and particularly provides a throat plane positioning method based on profile characteristics of an hourglass worm. The technicalsolution provided by the invention comprises: starting from the profile characteristics of the hourglass worm to separately position a left tooth surface or a right tooth surface on the basis of roughpositioning of a throat plane, recording indication values of a micro-displacement sensor through carrying out searching on a truncated cylindrical spiral line of a throat plane reference circle of the hourglass worm along an axial direction of the hourglass worm, calculating minimum-value point information through fitting an indication value curve, and obtaining a throat plane position of the side tooth surface. According to the throat plane positioning method based on the profile characteristics of the hourglass worm provided by the invention, one-time positioning success of a throat planeof the one side tooth surface can be realized, a positioning process is simple and reliable, efficiency is high, and a guarantee is provided for high-precision measurement of the hourglass worm.

Description

technical field [0001] The invention belongs to the technical field of precision measurement, and in particular relates to a throat plane positioning method based on the surface characteristics of a toroidal worm. Background technique [0002] The toroidal worm is a nonlinear worm, which has the characteristics of large number of meshing teeth, long instantaneous contact line, large bearing capacity, and high transmission efficiency. It has broad application prospects in the fields of ships, mining machinery, and aerospace. The processing of the toroidal worm is different from that of the ordinary cylindrical worm. When changing the machining tooth surface, the position of the tool grinding wheel needs to be adjusted so that the tool grinding wheel feeds from both sides of the toroidal worm axis to process the left and right tooth surfaces. The adjustment of the position of the tool grinding wheel causes the reference position of the left and right tooth surfaces of the toru...
