Abstract

The invention provides a tool for a pocket hole of a short cylindrical roller bearing retainer and a pocket hole method of the tool, relates to a tool for the pocket hole and the pocket hole method of the tool, and aims to solve the problem that due to the inconsistency between the axial position degree and the circumferential position degree of the pocket hole, the processing quality of the retainer is affected. According to the tool, a locating shaft is installed on a workbench in a rotatable mode, a locating rotating shaft is installed in a center hole formed in the locating shaft in a sleeved mode, and the retainer is installed on the locating shaft; a cover plate is installed on the retainer in a press mode, a stepped hole is formed in the middle of the cover plate, and a press block is installed in the stepped hole of the cover plate in a rotatable mode; and a press rod is vertically screwed into the press block, a screwing rod is horizontally arranged at the upper end of the press rod in a penetrating mode, and a locating pin is detachably inserted into the pocket hole of the retainer. The method comprises the steps that the tool for the pocket hole of the retainer is installed; the retainer is fixed; the position of the pocket hole to be broached is determined; the work of preparation before broaching is conducted; after a broaching machine is started, broaching of the pocket hole is accomplished; and broaching is conducted repeatedly until broaching of the pocket hole of the retainer is accomplished. The tool for the pocket hole and the pocket hole method of the tool are used for production of the bearing retainer.

Description

technical field [0001] The invention relates to a tooling for pocket holes in a cage and a pocketing method thereof, in particular to a tooling for pocket holes in a cage of a short cylindrical roller bearing and a pocketing method thereof. Background technique [0002] The solid cage of short cylindrical roller bearings is machined, and the pocket holes are generally processed by broaching. There are many factors that affect the machining accuracy of the pocket hole, including the material, structure, and manufacturing quality of the broach, the tooling structure and manufacturing quality of the broaching square hole, the choice of cutting fluid, the stability of the broaching machine, the determination of working parameters, and operator skills. So far, systematic research has been carried out on broaches, process flow, cutting fluid application, cutting parameters, etc., and the accuracy indicators of this type of cage pockets have been greatly improved. Through the analy...
