Bearing steel ball diameter automatic measurement and sorting equipment

Abstract

The invention relates to the technical field of bearing production, in particular to bearing steel ball sorting equipment capable of automatically measuring diameters. The bearing steel ball sorting equipment comprises a control cabinet, an automatic feeding mechanism, a differential type inductive-transducer diameter measurement mechanism and an automatic sorting mechanism. Automatic falling of steel balls is achieved through cooperation of a hopper, a steel ball baffle and a photoelectric sensor, a PLC system controls a cylinder to achieve automatic feeding, and a differential type inductive transducer is used for measuring the diameters of the steel balls so as to improve measurement precision. A sorting box is matched with PLC control to achieve automatic graded sorting of the steel balls, and unqualified steel balls are picked out. The automatic measurement and sorting process of the steel balls is achieved through automatic falling, high-precision steel ball diameter measurement through the differential type inductive transducer and the sorting box controlled by a PLC.

Description

technical field [0001] The invention relates to the technical field of bearing production and assembly, in particular to automatic measuring and sorting equipment for bearing steel ball diameters. Background technique [0002] The diameter of the steel ball directly affects the dynamic working characteristics of the bearing. Therefore, detecting the diameter of the steel ball before installation and sorting it has important practical significance for ball bearings. At present, most domestic bearing manufacturers use manual sorting or special measuring tools to measure and sort the diameter of steel balls. Among them, the manual sorting method has the longest application time and the widest application range. The detection of steel balls on the production line is still at the stage of a relatively primitive method, using a lever micrometer to detect steel balls. This method has the advantages of high detection efficiency, convenience and feasibility, but the resolution of the...

Problems solved by technology

Off-line detection of a large number of rollers requires a lot of manpower and material resources. According to relevant statistics, a skilled operator can complete the measurement of about 50-60 per minute, and a shift needs 8 to 10 workers. , and repeated mechanical labor for a long time will cause fatigue to the operator, resulting in deviations in measurement results, reduced work efficiency, and affected factory benefits.
