Comparative measurement method-based multi-parameter automatic measurement system of outer ring of rolling bearing

Abstract

The invention discloses a comparative measurement method-based multi-parameter automatic measurement system for an outer ring of a rolling bearing. The automatic measurement system comprises a feeding mechanism, a chained transmission mechanism, an axial parameter measurement apparatus, a radial parameter measurement apparatus, a separation mechanism, a PLC control module, an upper computer control module, and a man-machine interaction module. According to the measurement system, with utilization of a standard and high-precision inner ring of a bearing as a reference component as well as a camera and a digital dial gauge as comparative measurement instruments, a measured outer ring of the bearing is compared with the reference component so as to carry out separation of a qualified product, a reprocessed product and a scraped product. According to the invention, automatic comparative measurement of the outer diameter of an outer ring of a bearing and the variation thereof, an inner diameter and the variation thereof as well as the diameter of a groove and the variation thereof can be realized; and moreover, bottleneck problems that the system cost is too high due to a requirement of a high resolution ratio of a camera during the high precision detection and large-size detection of an outer ring of a bearing and the previous multi-parameter detection of an outer ring of a bearing needs to utilize special measurement instruments respectively to carry out measurement can be solved.

Description

technical field [0001] The invention relates to the field of measurement and testing, in particular to a multi-parameter automatic measurement system for the outer ring of a rolling bearing based on a comparative measurement method. Background technique [0002] Rolling bearings are the basic components that transmit motion and bear loads, and the processing and testing accuracy of each component directly affects the performance, life and reliability of rolling bearings. Bearing outer ring is an important component part of rolling bearing. After turning or grinding, parameters such as outer diameter, inner diameter and groove diameter need to be tested with high precision. At present, most of the bearing manufacturers in my country basically adopt semi-automatic and manual detection methods due to the low level of automatic detection, especially in the detection of bearing outer rings. The multi-parameter detection of bearing outer rings is performed in different The test pl...
