Problems solved by technology

The reasons are: 1. It is not easy to measure. The element to be measured is a small arc surface, the size of which is less than 1 / 3 of the circumference. For clamping, there is no effective clamping support surface and effective pressing and fixing surface. The only surface that can be used is a thin ring-shaped facet, which is easy to be biased when clamping and pressing
At present, a three-coordinate measuring machine is used for measurement, and a six-jaw chuck is used for clamping. The disadvantages are that the clamping efficiency is low, the data output by this measurement method has poor repeatability, and the data traceability is poor.

Abstract

The invention belongs to the detection technology and especially relates to an inertial rotor detection tooling. The tooling comprises a tooling main body (01) and a compaction cap (03). In the invention, through effectively using an inertial rotor structure, the local area of a detected surface is selected as an orientation, and measuring machine samping point touch is reasonably avoided. The large hole of the center step hole of an inertial rotor is used to carry out centering, and the small hole end surface of the center step hole of the inertial rotor is compressed. The inertial rotor structure is fully used and the effective measuring range of the large hole of the center step hole is increased. The inertial rotor is clamped, inertial rotor small arc surface measurement element pointpositions can be picked accurately, efficiency is high, repeatability is good, the tooling is traceable, a clamping error is small, and the precision of measuring machine sampling points is guaranteed.

Description

technical field [0001] The invention belongs to detection technology, and in particular relates to an inertial rotor detection tool. Background technique [0002] The inertia rotor is an important part of the navigation power tuning gyro. It has a special structure, high precision requirements, and difficult measurement. Different measuring equipment and different inspectors often have different measurement data, which brings some confusion to the measurement. The reasons are: 1. It is not easy to measure. The element to be measured is a small arc surface, the size of which is less than 1 / 3 of the circumference. For clamping, there is no effective clamping support surface and effective pressing and fixing surface. The only surface that can be used is a thin ring-shaped facet, which is easy to be biased when clamping and pressing. At present, a three-coordinate measuring machine is used for measurement and a six-jaw chuck is used for clamping. The disadvantages are low clamp...
