Abstract

The invention relates to a bounce measurement tool of an inner hole and an external diameter of a deep-hole part. The measurement tool is composed of a pedestal, a connection body, a support post, a supporting rod, a cross beam, a connecting rod, connecting assemblies, a movable rod, a meter clamping seat, a clamping plate and a dial indicator. The pedestal is combined with the support post by the connection body. One end of the cross beam is installed at the top of the support post by one connecting assembly; one end of the supporting rod is installed at the support post by one connecting assembly and the other end of the supporting rod is installed on the cross beam by one connecting assembly; one end of connecting rod is installed at a free end of the cross beam by one connecting assembly; one end of the movable rod is connected with a free end of the connecting rod and the other end of the movable rod is combined with the meter clamping seat by the clamping plate; and the dial indicator is installed on the meter clamping seat. When the measurement tool is in use, the inner hole and external diameter bounce of the measured deep-hole part meets the requirement; and the measurement speed and the measurement accuracy are improved.

Description

technical field [0001] The invention belongs to the inner hole and outer diameter runout measuring tool, in particular to the inner hole and outer diameter runout measuring tool of deep hole parts. Background technique [0002] For deep-hole parts with an inner hole depth of more than 800mm, an orifice diameter smaller than the measured inner hole diameter, and a large difference between the two (such as the engine rotor assembly in an aircraft, if the beating of the engine rotor assembly cannot meet the technical requirements, it will inevitably affect the rotor. The balance of the rotor will cause the vibration of the engine, especially for the core components of the machine such as the engine. If the rotor balance fails, it will cause huge economic losses, and even endanger life). It is easy to operate, it is difficult to improve the measurement speed and ensure the accuracy of the measurement. Because the operation of measuring the runout of the inner hole is carried ou...
