Problems solved by technology

Due to the wide variety of shaft-type blades, a lot of measuring tools are required, which not only makes it difficult to guarantee the time limit for blade processing, but also increases the processing cost of the blades (the manufacturing cycle of each set of measuring tools takes tens of days, and the manufacturing cost costs several thousand. to RMB 10,000) and storage costs

Abstract

A universal combined test tool for a shaft type blade comprises a base, a universal positioning block, an angle assisting positioning block, a mounting angle measuring device, a ruler, a movable section positioning block, a blade tip assisting positioning block, a blade tip height measuring device, a compression block, a first sample plate and a second sample plate. By using the combined test tool, the mounting angle, the section and the blade tip height of the shaft type blade can be measured. The measuring method comprises the steps of 1, the axial positioning and angle positioning of the to-be-measured shaft type blade and 2, the mounting angle measuring, the blade type measuring and the blade tip height measuring of the to-be-measured shaft type blade.

Description

technical field [0001] The invention belongs to measuring tools, and in particular relates to a general combined measuring tool for measuring the profiles, installation angles and blade tip heights (including conical surfaces, planes, slopes, arc surfaces, etc.) of different types of axial blades. Background technique [0002] The detection of shaft-type blades mainly includes the detection of blade profile, installation angle, and blade tip height. To complete the above-mentioned detection, using existing measuring tools, each type of shaft-type blade needs 4 sets of measuring tools, one of which is used for testing installation Angle, one set is used to detect the blade tip height, and two sets are used to detect the blade profile (the blade profile requires a set of measuring tools for coarse and fine). Due to the wide variety of shaft-type blades, a lot of measuring tools are required, which not only makes it difficult to guarantee the time limit for blade processing, bu...
