Method for measuring plane secondary enveloping ring surface hobbing cutter

Abstract

The invention relates to a method for measuring a plane secondary enveloping ring surface hobbing cutter, and belongs to the fields of the precision testing technology and instrument, the mechanical transmission technology and metal cutting tools. According to the method, numerical models of various errors of the hobbing cutter are built based on the gear space meshing mechanism and a corresponding worm tooth surface equation according to the definitions of the various errors of the hobbing cutter, coordinate conversion is carried out on the numerical models, the numerical models are resolved into motions of three axes of a measuring machine, and a numerical value solving method is adopted for obtaining numerical solutions of three coordinates. A computer conducts sampling route planning according to the numerical solution, the coordinate values are input into a numerical control system to control the motions of the three axes of the measuring machine, a data collecting system synchronously collects three-axis grating values and measuring head data, the collected data are processed, and the high-precision measurement on cutting edge spiral line errors, edge opening tooth shaped errors and scrap containing groove circular pitch errors of the plane secondary enveloping ring surface hobbing cutter is accordingly achieved.

Description

technical field [0001] The invention relates to a method for measuring a plane secondary enveloping torus hob, and belongs to the fields of precision testing technology and instruments, mechanical transmission technology and metal cutting tools. Background technique [0002] The planar quadratic enveloping toroidal worm pair is produced under the background of the development of the machinery industry towards high speed, heavy load and high efficiency, and is the basic part of mechanical transmission. This kind of worm pair has the characteristics of multi-tooth meshing, instantaneous double-line contact, large curvature radius, and large angle between the contact line and the relative sliding speed, which makes it have a large bearing capacity, high transmission efficiency, easy automatic lubrication, and long service life. [0003] With the development of science and technology, higher and higher requirements are put forward for the precision of the toroidal worm drive sys...
