Abstract

The invention relates to a binocular initiative vision monitoring device for precision machining. The feature is that it fixes three supports on base, and sliding rails are installed in the three supports and plumbing to bottom plane, sliding blocks are installed in the sliding rail, the round guiding rail connecting to the three sliding blocks, two dollies installed on the round guiding rail, each dollies having a cradle head that is installed a video camera. The base line and location between the two video cameras would be adjusted by sliding on the guiding rail. The vision system could flexibly adjust the observing anger. It has the advantages of parallel structure, simple moving mode and simple vision computing mode.

Description

technical field

[0001] The invention relates to the field of visual monitoring of mechanical processing, in particular to a binocular active visual device for monitoring the working space of precision machining of parallel machine tools. Background technique

[0002] Parallel machine tool is a new type of CNC processing equipment with parallel mechanism as the main body. Compared with traditional CNC machine tools, parallel machine tool is easy to realize six-axis linkage, and it is a kind of virtual axis machine tool.

[0003] The emergence of parallel mechanisms can be traced back to 1931. Gwinnett proposed an entertainment device based on spherical parallel mechanisms in his patent. In 1962, Gough invented a six-degree-of-freedom tire detection device based on parallel mechanisms. In 1965, German Stewart For the first time, the mechanism invented by Gough was studied in the sense of mechanism, and it was extended and applied to the motion generating device of the flight s...
