|1. (WO2018201337) IN-SITU SYSTEM FOR MEASURING SHAPE ERROR IN LARGE RING SURFACE|
|Applicants:||DALIAN UNIVERSITY OF TECHNOLOGY
|Title:||IN-SITU SYSTEM FOR MEASURING SHAPE ERROR IN LARGE RING SURFACE|
An in-situ system for measuring a shape error in a large ring surface 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 orientation adjustment platform (5) can adjust a rotation angle thereof with respect to a z axis and an x axis, and adjustment of angles thereof is controlled by the orientation adjustment platform motor (4). The orientation adjustment portion and the rotating portion are connected by means of the connection plate (6). The rotating portion comprises a rotating indexed disk base (7) and a high precision rotating indexed disk (1). When the rotating indexed disk (1) is to be rotated, the rotating indexed disk (1) is loosened by means of a wrench (11), and then manually rotated to a desired angle. Afterwards, the wrench (11) is pulled backwards for fixation. The measurement portion comprises a sensor clamp (10), a sensor holder (9), and a touch sensor (8). The sensor clamp (10) is positioned by means of a mandrel and the rotating indexed disk (1), and is fixed by means of two pairs of bolts and nuts (2). A total of four sets of sensor receptacles are arranged at the sensor clamp (10). Each set of sensor receptacles includes at least three receptacles. Each sensor receptacle receives one sensor holder (9) for fixing the sensor (8).
