Abstract

The invention provides a blade tenon tooth positioning device. The tenon tooth positioning device comprises a base and a plurality of blocking teeth which are arranged on the base at intervals, wherein a first positioning inclined surface and a second positioning inclined surface which are oppositely arranged are respectively arranged on the adjacent first blocking tooth and the second blocking tooth; and an included angle between the first positioning inclined surface and the second positioning inclined surface is matched with a tooth-shaped angle of a to-be-positioned blade tenon tooth. According to the technical scheme adopted by the invention is applied, the blade tenon tooth positioning device can be used for realizing reliable matching between the plurality of the blocking teeth and the blade tenon tooth, good in stability, and has relatively good measuring precision.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a blade tenon tooth positioning device. Background technique [0002] In the field of aviation machinery, when the blade part is installed on a measuring tool with a blade tenon tooth positioning device for measurement, the tenon tooth part of the part is fixed by the tenon tooth positioning device, and then the distance from the intersection point to the tenon tooth symmetry center is measured by a meter (ie measured size). The device can not only accurately fix the position of the parts, but also meet the measurement requirements, so as to process qualified parts. [0003] The original blade tenon tooth positioning device adopts a fitting blade tooth shape positioning piece designed according to the structural size of the tenon groove used for matching with the tenon tooth, and a groove with a width of 2 mm is opened along the axial direction of the tenon tooth. The materi...
