Abstract

The invention provides a measurement device of a long-shaft part. The measurement device comprises a fixture body and a measurement body, wherein the fixture body is used for fixedly locating the long-shaft part to the measurement body; the measurement body is a three-coordinate measuring machine and is used for measuring the dimensions of the long-shaft part; the fixture body comprises a first fixture part and a second fixture part, wherein one end of the long-shaft part is installed on the first fixture part, and the other end of the long-shaft part is installed on the second fixture part; and the first fixture part and the second fixture part are provided with a first V-shaped slot and a second V-shaped slot respectively. Through the measurement device, measurement of the long-shaft part can be completed accurately and efficiently.

Description

technical field [0001] The invention belongs to the field of mechanical processing detection methods, and in particular relates to a measuring device and a use method for long-axis parts. Background technique [0002] Low-pressure turbine shaft parts have complex structures, many measurement dimensions, and strict tolerances. The outer diameter of the long shaft is composed of multiple shafts with different sections. The total length of the part is more than 1.5 meters. At present, when measuring the dimensions of the outer surface of the long axis, a 2-meter caliper is required. Two people cooperate to measure, and the measurement stability is poor. The processing size of the inner cavity is only guaranteed by the program, and the dimensional accuracy cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to provide a measuring device and usage method for long-axis parts, which solves the defects of poor stability and unguaranteed...
