Abstract

The invention discloses an inner hole size measuring device. The device includes a first mounting assembly extending in a first direction, a second mounting assembly movably connected to the first mounting assembly and at least one measuring device body which is rotatably connected with the second mounting assembly; the measuring device bodies can extend into a hole of a measured piece, the axialpositions of the measuring device bodies in the hole are adjusted through the first mounting assembly, and the radial positions of the measuring device bodies in the hole are adjusted through the second mounting assembly. The provided inner hole size measuring device can be used for detecting the inner hole of a component, especially a complex inner hole.

Description

technical field [0001] The invention relates to the technical field of inner hole detection equipment, in particular to an inner hole size measuring device. Background technique [0002] With the advancement of modern science and technology, the processing and measurement of hole parts in the fields of automobiles, aerospace and other fields are getting higher and higher. In actual production, parts with inner hole structures are often encountered, and the inner hole Overall dimensions are often the critical dimensions of the part. [0003] At present, there are many methods for measuring the inner hole of parts. Vernier calipers or inner micrometers are often used for measurement. However, caliper measurement is greatly affected by factors such as the technical proficiency level of the operator, and for some complex inner hole measurements, caliper measurement can no longer meet the demand. [0004] Therefore, it is very necessary to design a device that can measure the si...
