Abstract

The invention discloses a coaxiality measuring device and method for a mechanical part. The device comprises a measuring seat, a positioning element, a lever, and an indication meter. The positioning element arranged at the measuring seat is used for localizing a to-be-measured part by using a reference hole of the to-be-measured part as a reference; the lever arranged at the measuring seat is used for transferring a measurement position of a to-be-measured inner hole of the to-be-measured part and enabling coaxiality measurement of the to-be-measured part to be converted into bounce value measurement of the lever; and the indication meter that is arranged at the measuring seat by corresponding to the position in contact with the inner hole of the to-be-measured part by the lever is used for measuring a bounce value of the lever. On the basis of the force transmission effect of the lever, the measurement position of the to-be-measured inner hole of the to-be-measured part is transferred, complete contact of two buses of the reference hole of the to-be-measured part with two lines of the positioning element, and radial circular bouncing of the to-be-measured part is transformed into bouncing of the lever, so that a system error caused by the clearance fit of the to-be-measured inner hole of the to-be-measured part and the external circular surface of the traditional measuring tool can be eliminated. Meanwhile, the manufacturing difficulty of the measuring device can be reduced. The measuring device can be used conveniently and measurement becomes precise.

Description

technical field [0001] The invention relates to the field of detection of mechanical parts, in particular to a device and method for measuring coaxiality of mechanical parts. Background technique [0002] Currently, it is necessary to figure 1 The coaxiality of the part to be tested shown in is measured, wherein the part to be tested includes a reference hole 100 and an inner hole 200 integrally communicated with the reference hole 100 . When measuring the coaxiality of the part to be tested, it is necessary to measure the coaxiality between the reference hole 100 and the inner hole 200 to be tested. The existing general measurement methods include the coaxiality measuring instrument (gyroscope measurement) measurement method , V-shaped block metering measurement method and mandrel measurement method, etc. However, the coaxiality measuring instrument method and the V-shaped block metering measurement method cannot be measured during processing, and the coaxiality measuring ...
