The invention discloses a cylindrical roller bearing copper holder pocket hole milling fixture. The cylindrical roller bearing copper holder pocket hole milling fixture comprises a transition disc fixedly connected with a machine tool spindle, a chuck fixedly connected to the transition disc, a middle pull rod connected with a machine tool piston rod, a front pull rod connected to the middle pull rod, a gland fixed to the front pull rod and a torsion-resisting disc which is mounted on the front pull rod and matched with the chuck for fixing a holder. A penetrating hole allowing the front pull rod to penetrate is molded in the middle of the torsion-resisting disc, a plurality of milling cutter inlet and outlet through holes are molded in the torsion-resisting disc in the circumferential direction at equal intervals, and a holder circular bead positioning groove is molded in one end, facing the chuck, of the torsion-resisting disc. The copper holder pocket hole milling fixture is simple in structure, convenient to debug, easy to machine, short in clamping time, and capable of stably positioning a holder circular bead, so that the circular bead cannot deform, and the machining precision is ensured.
Description
technical field [0001] The invention belongs to the field of bearing processing equipment, and in particular relates to a pocket milling jig for a copper cage of a cylindrical roller bearing. Background technique [0002] The traditionally used copper cage pocket milling jig for cylindrical roller bearings, when milling the cage pocket, one end of the cage is positioned with a small cylinder, there is a relatively large gap between the inner diameter of the cage and the outer diameter of the cylinder for easy installation , so there is no way to ensure the concentricity of the cage and the milling machine spindle. Therefore, the pockets milled out of the cage have some problems, such as deep and shallow, and relatively large dispersion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pocket milling fixture for copper cages of cylindrical roller bearings with simple structure, convenient debugging, simple proce...
