Problems solved by technology

[0003] In the production process, some parts have irregular and small structures in local areas, and they have high requirements for the geometrical tolerance of the structural surface. When detecting the geometrical tolerances of such irregular structures, if the general However, there is a problem that it cannot be detected due to the small structure; the current conventional detection method for this structure is to use a special projector for detection, but the operation process of using a projector is complicated and the detection efficiency is low. , the input cost is high, and many manufacturers do not have projectors, so it is not universally practical

Abstract

The invention discloses a detection device for detecting the form and location tolerance of an irregular structure. The detection device comprises a base plate and a detection part, wherein the detection part consists of a support block, a slide rail and a detection block. The detection device is characterized in that the slide rail is fixed to the support block; the detection block can slide horizontally along the slide rail; at the same time the detection surface of the detection block fully simulates a structural profile to be detected; and the working part of the detection surface is made to be a passing and stopping structure according to the tolerance required by the structural profile to be detected. When the passing end of the detection block can successfully pass through the detected structural profile, and a stopping end can stop the detection block from passing, the detection profile of the structure is qualified, otherwise the detection profile is unqualified.

Description

technical field [0001] The invention relates to the technical field of shape and position tolerance detection, in particular to a detection device that can be used to detect shape and position tolerances of irregular structural profiles. Background technique [0002] The detection device is a special detection equipment designed and manufactured to detect the external dimension, surface shape and other position status of the product. At the part production site, the shape, outline and hole size of the part can be detected through the detection device, so as to ensure the rapid judgment of the quality status of the part during production. [0003] In the production process, some parts have irregular and small structures in local areas, and they have high requirements for the geometrical tolerance of the structural surface. When detecting the geometrical tolerances of such irregular structures, if the general However, there is a problem that it cannot be detected due to the s...
