On-line diameter measurement device for large-diameter solid of revolution

Abstract

The invention discloses an on-line diameter measurement device for a large-diameter solid of revolution, and the device comprises a first measurement group and a second measurement group, wherein the first measurement group and the second measurement group are symmetrically arranged on two sides of a measured solid of revolution; the first measurement group and the second measurement group are symmetrical to the axis of the measured solid of revolution; the two measurement groups respectively correspond to two ends of the measured solid of revolution; each measurement group comprises a transmitting end for transmitting measurement lights, a receiving end aligned with the transmitting end and an adapting piece for connecting the transmitting end and the receiving end; the measured solid of revolution is positioned between the transmitting end and the receiving end; the measured lights are formed into blocked lights and residual lights after meeting the measured solid of revolution, wherein the blocked lights are blocked by the measured solid of revolution and can not be transferred to the receiving end, and the residual lights penetrate through the measured solid of revolution to reach the receiving end; the receiving end receives the residual lights and calculates the light band width of the residual lights; the receiving end inputs the light band width into a processor; and the processor calculates to obtain the diameter of the measured solid of revolution. The on-line diameter measurement device has the advantages of high measurement precision and low manufacture cost.

Description

technical field [0001] The invention relates to an online diameter measuring device of a large-diameter revolving body. Background technique [0002] For a long time, with the development of large-scale mechanical equipment in the direction of complexity and precision, the inspection requirements for the processing quality of large-sized workpieces required by these equipments have also been continuously improved. Scholars at home and abroad have done a lot of research on the measurement of the diameter and related parameters of rotary parts, but there has been no ideal method and instrument for large diameter measurement, especially in the machinery industry, large-scale precision measurement has not yet been well resolved. The object of the present invention is to research and develop on-line precise measurement of diameter parameters of large-size revolving body parts through the construction of sensors. [0003] At present, the methods of diameter measurement mainly inc...
