Description

Comprehensive detecting tool for relative angles and positions of dense bead type double-intersecting holes

Technical Field

The utility model belongs to the field of double-intersection hole detection, and relates to a dense-bead type double-intersection hole relative angle and position comprehensive detection tool.

Background

The existing synchronizer is combined with a gear ring, six groups of double-phase intersecting holes are formed in one circumference, and six groups of flat pins are matched with the matched conical rings. The six sets of two-phase intersections are required to have relative position requirements, and the two "single-hole" apertures of the individual two-phase intersections have relative angular requirements.

At present, no proper gauge can be used for measuring operators on a production line, if the operators need to send a three-coordinate measuring instrument to measure, the operation is complex, the measurement efficiency is greatly reduced, the detection cost is increased, the resources are wasted, and the operators are inconvenient to monitor the stability of the machining quality in the process of machining double-intersecting holes. In the prior art, by three-coordinate measurement, the measurement efficiency is low, the detection time is long, and the detection cost is high. In contrast, for example, in the conventional CN214666466U, a position degree detection device for a through hole of a synchronizer ring gear can detect the position degree of the synchronizer ring gear, but it can only measure the position degree, but cannot detect the angle.
