A device for judging the front and back sides of a cage

Abstract

The invention discloses a device for judging the front and back sides of a cage, which comprises a frame, a cage positioning mechanism, a cage judging mechanism, a cage lifting mechanism and a main control machine; the cage positioning mechanism, the cage judging mechanism, the cage The lifting mechanism is installed on the frame, the cage positioning mechanism is connected in parallel with the cage discrimination mechanism, and the cage lifting mechanism is located at the end of the cage discrimination mechanism; when judging: make one of the end faces of the cage form a 45-degree angle with the horizontal plane, because The chamfer of the center hole of the cage is generally 45 degrees. At this time, the angle between the chamfer of the center hole of the cage and the horizontal plane is 0 degrees. At this time, the width of the chamfer of the center hole of the cage captured by the camera is the actual Width, the front and back of the cage can be judged according to the width of the chamfer captured at this time and the width of the reference chamfer; the fully automatic judgment reduces human labor and improves the discrimination efficiency of the cage, which can be well used in production .

Description

technical field [0001] The invention belongs to the technical field of mechanical parts testing equipment, and in particular relates to a front and back side discrimination device of a cage. Background technique [0002] The cage partially wraps all or part of the rolling elements and moves with them to isolate the rolling elements, guide the rolling elements and keep them in the bearing. For cages on equipment with high speeds such as automotive transmissions, the requirements for dimensional accuracy are very high. If the dimensional accuracy of the cage is not up to standard during the production process, installing it on the vehicle will cause excessive wear of the cage, affecting the service life of the ball cage, or driving safety issues. The cage mentioned in the present invention refers to a metal member whose inner and outer surfaces are spherical and both ends are planes formed after turning. Such as figure 1 As shown, in the existing cage processing technology,...
