|1. (WO2018201340) IN-SITU METHOD FOR MEASURING SHAPE ERROR IN FLAT RING SURFACE|
|Applicants:||DALIAN UNIVERSITY OF TECHNOLOGY
|Title:||IN-SITU METHOD FOR MEASURING SHAPE ERROR IN FLAT RING SURFACE|
An in-situ method for measuring a shape error in a flat ring surface is realized on the basis of an in-situ measurement system for measuring a shape error in a large ring surface. The in-situ measurement system comprises an orientation adjustment portion, a rotating portion, and a measurement portion. The orientation adjustment portion comprises an orientation adjustment platform (5), an orientation adjustment platform motor (4) and a connection plate (6). The rotating portion comprises a rotating indexed disk base (7) and a high precision rotating indexed disk (1). The measurement portion comprises a sensor clamp (10), a sensor holder (9), and a touch sensor (8) and a related apparatus thereof. The measurement system realizes application of a three-point method in measurement of a shape error in a flat ring surface and improves an algorithm capable of realizing application of the three-point method in in-situ measurement of a shape error in a flat ring surface, thereby realizing in-situ measurement of a shape error in a flat ring surface, greatly reducing an amount of time required for processing a small part, and mitigating an impact on precision of the part due to repeated clamping operations.
