Description

Tool of short-term test product external screw thread Technical Field The utility model belongs to the technical field of thread detection, and particularly relates to a jig for rapidly detecting external threads of a product. Background The metric external screw thread piece is widely applied to the fields of machinery, automobiles, aerospace and the like, has the characteristics of simple manufacture and convenient pairing, and after the screw thread piece is produced, whether the external screw thread size is qualified or not needs to be detected, and the external screw thread detection is not only a key step for ensuring the quality and the safety of products, but also an important means for improving the production efficiency, reducing the cost and meeting the industry standard. Currently, for external thread detection in the market, the detection is usually performed manually by a worker, and the manual detection consumes a lot of time, and the worker is tired after detecting for a long time, so that the qualification rate and the efficiency of the detection can be affected. Therefore, in order to solve the above-mentioned technical problems, it is necessary to provide a fixture for rapidly detecting the external threads of a product. The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Disclosure of utility model The utility model aims to provide a jig for rapidly detecting external threads of a product, which can solve the problem of low detection efficiency of the external threads by the existing manual work.
