Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a device and method for detecting and judging the radius of different convex arcs. Background technique [0002] The arc degree refers to the roundness of the arc. The arc is mainly determined by the arc length and the arc radius. When the arc length is constant, the arc radius determines the curvature (curvature) of the arc. The roundness of the arc is important for improving Mechanical manufacturing and installation accuracy and prolonging the working life of the machine play a very important role. Therefore, it is very important to detect the convex arc radius and determine the arc degree. In the prior art, there are many methods for detecting the radius of a concave arc and judging the degree of the arc, for example, measuring the radius of the arc with the method of bow height and chord length, measuring the radius of the arc with the method of rotation, measuring the ...
