Novel tool for bearing cage locking port machining

Abstract

The invention relates to a novel tool for bearing cage locking port machining. The novel tool comprises a riveting upper mold and a riveting lower mold; the riveting lower mold is provided with an U-shaped groove upwards opened for placing a cage; the U-shaped groove is provided with two arc limiting holes for placing balls near a lowest end; the two limiting holes are symmetrically formed in the center line of the U-shaped groove; the riveting upper mold is arranged above the cage in an area between the two limiting holes; the riveting upper mold and the riveting lower mold form a space perpendicular relation; an upper mold positioning block is arranged above the riveting upper mold; two sides of the riveting lower mold are connected with lower mold positioning molds through dowel pins; and a limiting block is arranged out of the outer periphery of the upper mold positioning block above the lower mold positioning modules. The tool is simple in structure, has precise positioning and limiting functions, and can conveniently machine a needed locking port; and after the assembly of the tool is debugged, a pin hole is machined and a pin is assembled, so that the repeated positioning precision is improved, the realization is easy, and the machine tool equipment cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of cylindrical roller bearings without inner ring, in particular to a novel tooling for processing the lock of a bearing cage. Background technique [0002] Roller bearings without inner ring are relatively tight in structure and can withstand larger radial loads, so they have been widely used. However, due to their own structural limitations, the cage pockets must have a locking function. At present, most of this type of cage adopts a separate structure, which is troublesome to manufacture. For this reason, the cage is designed as an integrated structure. The pocket space structure adopts a rectangular parallelepiped, which is convenient to manufacture. The rollers are pressed from the inner hole of the cage. Precise size and function of locking rollers. Therefore, it is necessary to design the lock processing tooling of the cage. Summary of the invention [0003] The technical problem to be solved by the prese...

Problems solved by technology

[0002] Roller bearings without an inner ring are relatively compact in structure and can withstand large radial loads, so they have been widely used. However, due to their own structural limitations, the pockets of the cage must have a locking function.

At present, most of this type of cage adopts a separate structure, which is troublesome to manufacture. Therefore, the cage is designed as an integrated structure. The pocket space structure adopts a cuboid, which is convenient to manufacture. The roller is pressed from the inner hole of the cage. Precise size and lock roller function
