Method for acquiring fixed point positions of six-point type clamping jaw of general rigid plate

Abstract

The invention relates to the technical field of industrial automatic plate positioning, in particular to a universal rigid plate six-point type clamping jaw fixing point position obtaining method which comprises the steps that (1) a file is configured, a standard DXF file containing a graph is imported, and a machining graph is analyzed and obtained; judging whether the processing graph is connected end to end and is closed or not; if yes, entering the next step; (2) judging whether the processing graph is legal or not; if yes, drawing a limit, and generating a calculation auxiliary line for a user to drag; (3) segmenting the legal processing graph, and obtaining segmented graph data; and performing fillet compensation on the segmented graphic data after expanding and deviating according to the radius of the positioning clamp or the positioning wheel to obtain a moving path of the positioning clamp or the positioning wheel, and generating an auxiliary line which can be moved by a user and is used for determining a positioning point. By means of the method, high-precision plate positioning supporting complex special-shaped plates can be achieved, operation is easy and convenient, universality is high, and the calculation process is visual.
