Bearing inner ring diameter detection device and detection method thereof

Abstract

The invention discloses a bearing inner ring diameter detection device and a detection method thereof, and belongs to the technical field of bearing inner ring detection. The bearing inner ring diameter detection device comprises a base, and feed mechanisms, transfer mechanisms, detection mechanisms and discharge mechanisms which are mounted on the base, as well as a control unit, wherein the feed mechanisms are mounted on the side edges of transfer mechanism conveying belts; the detection mechanisms are mounted on the side edges of transfer mechanism displacement sheets; the discharge mechanisms are located below the displacement sheets; to-be-detected bearing inner rings on the feed mechanisms are conveyed to the detection mechanisms by the conveying belts and the displacement sheets, and displaced to the discharge mechanisms by the displacement sheets after detection; the displacement sheets are displaced by expansion of piston rods of station clamping air cylinders and station pushing air cylinders which are connected with the displacement sheets; and the control unit is connected with the feed mechanisms, the transfer mechanisms, the detection mechanisms and the discharge mechanisms respectively by signal lines.

Description

technical field [0001] The invention relates to a bearing inner ring aperture detection device and a detection method thereof, belonging to the technical field of bearing inner ring detection. Background technique [0002] Bearings are important basic components of various mechanical equipment, including outer rings, inner rings and balls, etc. Among them, the accuracy of the bore size, roundness and taper of the inner ring of the bearing directly affects the accuracy and performance of the bearing. [0003] At present, my country's bearing inner ring aperture detection is still basically at the level of manual detection. Low detection efficiency and low stability are the biggest drawbacks currently existing. Although the "Bearing Inner Diameter Automatic Detector" with publication number 102139268A discloses an automatic detection device for bearing inner diameter, it needs to rely on the feeding cylinder to push the inner ring of the bearing to be tested to the station dur...
