Abstract

The invention relates to a detection device and a method for detecting an outer diameter, a runout value and roundness of a circular shaft. The detection device comprises a base portion, an optical measurement portion, a center portion and a personal computer (PC)-programmable logic controller (PLC) control center, wherein the base portion comprises a base board and two base board guide rails, the optical measurement portion and the center portion are installed on the base portion in a sliding mode, the optical measurement portion comprises an optical measurement instrument guide rail and an optical measurement instrument, the optical measurement instrument guide rail is arranged on the base board guide rails in a sliding mode, the optical measurement instrument is arranged on the optical measurement instrument guide rail in a sliding mode, the center portion comprises a center guide rail, a first center structure and a second center structure, the first center structure and the second center structure are arranged on the center guide rail in a sliding mode, and the PC-PLC control center controls the optical measurement portion and the center portion to move relative to the base portion. The optical measurement instrument is used for measuring a round shaft to be detected, measured data are fed back to the PC-PLC control center, and the PC-PLC control center calculates the outer diameter, the runout value and the roundness of the circular shaft to be detected 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...
