Ball embedding device of bearing retainer

Abstract

The invention discloses a ball embedding device of a bearing retainer. The ball embedding device comprises a base and a boss formed on the base, a plurality of inserting holes are formed in the boss,material pushing rods are inserted into the inserting holes, the material pushing rods extend out of the outer wall of the boss and are provided with annular check rings, compression springs sleeve the material pushing rods in an inserted mode, the two ends of the compression springs abut against the check rings and the boss respectively, vertical pin shafts are inserted and fixed to the ends, away from the compression springs, of the material pushing rods, the lower ends of the pin shafts extend out of the material pushing rods, and guide wheels sleeve the lower ends of the pin shafts in an inserted mode; and an installation groove is formed in the lower end face of the boss, a driving cam is inserted into the installation groove, a plurality of protruding parts are formed on the drivingcam, a plurality of receding grooves penetrating through the outer wall of the boss are formed in the installation groove, the protruding parts penetrate out of the receding grooves, supporting lugs are formed on the protruding parts on the two sides of the driving cam, the supporting lugs are hinged to a piston rod of an air cylinder, the air cylinder is hinged to the base, and a guide wheel abuts against the protruding parts. The balls do not need to be sorted, the assembly mode of the retainer and the balls is simplified, and therefore the assembly efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bearing assembly equipment, in particular to a ball embedding device of a bearing cage. Background technique [0002] Bearings generally consist of an outer ring, an inner ring, a cage and balls, and the balls are held between the outer ring and the inner ring by the cage. During the assembly process of the bearing, the balls need to be embedded in the cage, and then the cage is assembled to the outer ring. When assembling the balls and the cage, it is necessary to sort the number of balls first, move the selected balls to the tray individually, and then buckle the inverted cage, and press the balls into the cage from the opening of the cage. The structure of this assembly method is relatively complicated, and the ball assembly efficiency is low. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the prior art, to provide a ball insertion device...
