Abstract

The invention discloses an auxiliary measuring device and method for the width of inner and outer ring flow channels between blades of a cartridge receiver assembly, and belongs to the field of machinery. The auxiliary measuring device comprises a cross-shaped positioning frame and a body; stepped pins are arranged at two ends of the positioning frame; a first sliding block is arranged on the bodylocated on one side of the positioning frame, a first sliding block cover plate is arranged on the first sliding block, a first clamping jaw is arranged on the bottom surface of the first sliding block cover plate, and a first positioning pin is arranged on the first clamping jaw; and the body positioned on the other side of the positioning frame has the same structure. According to the auxiliarymeasuring device, the stepped pins on the positioning frame are clamped on the outer ring to position the whole device, and the two stepped pins are clamped on the outer ring of the cartridge receiver; the body is provided with the sliding blocks and the sliding block covers, the two sliding block covers are respectively provided with the clamping jaws with the positioning pins, the positioning pins are used for positioning the flow channel walls, and rapid distance measurement can be achieved with the help of measuring tools like calipers.

Description

Technical field[0001]The invention belongs to the field of machinery, in particular to an auxiliary measuring device and method for the width of the inner and outer circulation channels between the blades of a casing assembly.Background technique[0002]Many aero-engine stator receiver components need to measure the width of the inner and outer circulation channels between the blades. Such parts are composed of outer ring, inner ring, and blades through welding. There are a large number of blades (generally more than 100 pieces), The narrow space between the blades brings a lot of data measurement and data processing work. At present, a three-coordinate measuring machine is usually used to measure the actual value of the radius at a fixed point on the inner and outer circulation channel surface, and the actual value of the channel width is calculated through the actual value of the corresponding point. The measurement workload is large and the data processing time is long.Summary of t...
