Problems solved by technology
[0002] When testing the symmetry of the gear tooth groove, ordinary measuring tools are used. Since the two sides of the gear teeth are arc-shaped, it is difficult to determine the symmetrical tangent point of the gear tooth groove by the usual detection method, and the detection accuracy is not high. And the detection efficiency is very low

Description
technical field [0001] The invention relates to the technical field of measurement and inspection tools, in particular to a gear tooth groove symmetry detection device. Background technique [0002] When testing the symmetry of the gear tooth groove, ordinary measuring tools are used. Since the two sides of the gear teeth are arc-shaped, it is difficult to determine the symmetrical tangent point of the gear tooth groove by the usual detection method, and the detection accuracy is not high. And the detection efficiency is very low. Contents of the invention [0003] In view of the above problems, the present invention provides a gear tooth groove symmetry detection device, which can conveniently determine the symmetrical tangent point of the gear tooth groove, ensure the detection accuracy, and greatly improve the detection efficiency. [0004] Its technical solution is as follows: a gear cogging symmetry detection device, which includes a base, characterized in that: the ...
