Gear Angle Offset Measuring Device and Measuring Method Based on Laser Displacement Sensor

Abstract

The invention discloses a gear angle offset measurement device and a measurement method based on a laser displacement sensor in the technical field of gear measurement. The measurement device includes a workbench on which a workpiece rotary table and a two-coordinate translation mechanism are arranged. The two-coordinate translation mechanism includes The X-axis guide rail fixed on the upper side of the worktable, the center positioning mandrel is vertically arranged on the workpiece rotary table, the Y-axis guide rail is slidably connected to the Y-axis guide rail, and the lifting frame is slidably connected to the Y-axis guide rail. A laser displacement sensor is connected to the top, and the center plane of the X-axis guide rail passes through the center of the workpiece turntable. The base of the laser displacement sensor is an angle-adjustable indexing plate. By adjusting the indexing plate, the position of the laser beam relative to the gear center is changed for offset measurement. The present invention can realize the measurement of complex gears, and the tooth surface data has no fluctuation during the measurement process, and the precision is good.

Description

Gear angle offset measurement device and measurement method based on laser displacement sensor technical field The present invention relates to a kind of gear measurement method, particularly the gear angle offset measurement based on laser displacement sensor [0001] quantitative method. Background technique Gear measurement technology can be divided into two categories: measurement during contact and non-contact measurement. The contact between the touch probe or the scanning sensor probe and the surface of the geometric body to record the three-dimensional coordinate position of the surface point of the body. Touch measurement method, this method is complicated to operate, has the problem of lateral resolution caused by the large radius of the touch probe, and requires Probe movement path should be planned in advance. Contact measurement can effectively measure spur gears, helical gears, etc. When the touch probe probe measures the spiral gear, the contact surfa...
