Abstract

The invention is applied to the technical field of detection, and particularly relates to a method and device for detecting the linearity and perpendicularity of equipment. The method comprises the following steps of fitting and generating a mark point straight line of an X axis according to pixel coordinates of mark points in M1 acquired images, and generating a linearity testing result of the X axis of the equipment; fitting and generating a mark point straight line of a Y axis according to the pixel coordinates of the mark points in the M1 acquired images, and generating a linearity testing result of the Y axis of the equipment; generating an included angle Thetaxy between the X axis and the Y axis according to Thetax and Thetay, and generating a perpendicularity testing result of the X axis and the Y axis of the equipment. According to the method and the device, the existing problems of low equipment linearity and perpendicularity detection efficiency and high cost are solved, the application range of equipment linearity and perpendicularity detection is widened, and the equipment linearity and perpendicularity detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a detection method and device for straightness and verticality of equipment. Background technique [0002] In the process of equipment production and assembly, due to mechanical processing, assembly, application environment, etc., there is a certain deviation of straightness and verticality in the XY axis of the equipment. The straightness and verticality of the XY axis directly affect the detection performance of the entire equipment. and detection accuracy. Straightness measurement is the most basic item in the field of geometric metrology, and it is the basis of geometric measurement such as flatness, parallelism, perpendicularity, and coaxiality. Straightness measurement is also a very important content in the machinery manufacturing industry. Together with dimensional accuracy, roundness and roughness, it is called the four major factors affecting product qual...
