Abstract

A detection device, comprising a base (110), an optical measurement portion (120), a centering portion (130), and a PC-PLC control center; the base (110) comprises a substrate (112), and two substrate guide rails (113); the optical measurement portion (120) and the centering portion (130) are slidably installed on the base (110); the optical measurement portion (120) comprises an optical measurement instrument guide rail (122) and an optical measurement instrument (123); the optical measurement instrument guide rail (122) is slidably disposed on the substrate guide rail (113); the optical measurement instrument (123) is slidably disposed on the optical measurement instrument guide rail (122); the centering portion (130) comprises a centering guide rail (132), and a first centering structure (133) and a second centering structure (135) slidably disposed on the centering guide rail (132); and the PC-PLC control center controls the movement of the optical measurement portion (120) and the centering portion (130) relative to the base (110). Also disclosed is a method of detecting the circular shaft outer diameter, runout value and roundness using the detection device, the method comprising: using the optical measurement instrument (123) to measure a to-be-detected circular shaft; feeding back the measured data to the PC-PLC control center; and the PC- PLC control center calculates the outer diameter, runout value and roundness of the to-be-detected circular shaft according to the measured data.

Description

technical field [0001] The invention relates to an optical detection device, in particular to a detection device and a detection method that can be used to detect the outer diameter, runout value, true roundness and the like of a shaft. Background technique [0002] At present, with the rapid development of the industry, in order to avoid the wear or failure of the applied equipment due to the excessive fluctuation of the outer diameter, runout value and roundness of the round shaft parts, it is necessary to detect the round shaft parts. In the measurement industry, the existing technologies mostly use parallel light, scanning parallel beam or expanded beam to irradiate the measured object at a parallel light speed, and measure the projected size of the light speed scanning occlusion time, or the measurement of the parallel light occlusion position. However, such measurement methods are mostly semi-automatic: inspectors need to hold optical measuring instruments to measure t...
