Abstract

The invention discloses a visual inspection device for special-shaped workpieces. The visual inspection device is composed of a visual inspection device body. The visual inspection device body comprises an optical carrying table, a first precise slewing bearing, a first multidirectional visual measurement system, a second precise slewing bearing and a second multidirectional visual measurement system; a first precise slewing bearing and a second precise slewing bearing are arranged at the two ends of the optical carrying table respectively, and a first multi-direction vision measurement system and a second multi-direction vision measurement system are sequentially connected between the first precise slewing bearing and the second precise slewing bearing in the axial direction; each of the first multi-direction vision measurement system and the second multi-direction vision measurement system comprises a radial dimension measurement vision mechanism, an axial dimension measurement vision mechanism and a rotary workpiece to be measured; the method is suitable for application occasions with high requirements for on-site rapid and precise measurement, and solves the problem of on-line rapid and precise measurement of the type of workpieces at present.

Description

technical field [0001] The invention relates to the technical field of industrial detection, in particular to a visual precision detection device for measuring special-shaped workpieces. Background technique [0002] In industrial production applications, there is a need for fast and accurate measurement of the geometric quantities of a class of parts after assembly, such as on-axis parts, rotating saw teeth, and rotary flywheels. The radial distance between the rotating parts and the axial distance between the rotating parts are important indicators for measuring the installation and rotating accuracy, and they are also the key problems of geometric quantity measurement to be solved in this patent. The topological structure of the DUT is as figure 1 As shown, the measurement difficulties are described as follows: (1) the length in the axial direction has a certain degree of ductility, and the length is different; (2) the radial direction also has a certain degree of ductil...
