An online video multiplier workpiece detector

Abstract

The invention discloses an online video magnification workpiece detector. A rapid positioning mandrel is connected above the main frame of the instrument, and a camera mounting body is installed below the main frame of the instrument, and a CCD industrial sensor with a magnification lens is installed inside. Camera, the display screen of the CCD industrial camera is installed in front of the main frame of the instrument, and the quick positioning mandrel above the main frame of the instrument is set coaxially and concentrically with the magnification lens of the CCD industrial camera installed in the camera installation body. The present invention is directly installed on the fast positioning fixture of the spindle of the numerical control and digital display processing machine tool, and the measured workpiece on the workbench is directly photographed with the lens of the CCD industrial camera, and the video image is enlarged and transmitted to the display screen, and is set in the center of the display screen. Some cross marks are used to position the detection reference of the workpiece to be tested, and then the moving table drives the invention to move to each detection position of the workpiece to be tested, and the cross marks are used for comparison and measurement, and the accurate information is obtained from the digital display table of the processing machine tool. measured value.

Description

technical field [0001] The invention belongs to the technical field of measuring equipment and instruments, and relates to a measuring instrument for online detection of workpieces, in particular to an online video multiplying workpiece detector. Background technique [0002] In the existing precision mold processing industry, for the processing and measurement of precision molds, the detection method usually used is the method of measurement after processing. The detection instruments used are: industrial microscopes, optical projectors and secondary detectors, etc. Wait. It uses the photoelectric principle to enlarge the precision workpiece, and then uses the electronic ruler and digital display meter to measure the structural size of the workpiece or the positional accuracy of the structure. Adopt above-mentioned measuring instrument, must unload the finished part from machine tool, put on the machine platform of measuring instrument again and just can detect. If the wo...
