Abstract

The invention provides a bearing riveting and pressing tool, which comprises a positioning sleeve, a press mold, ejector rods, disc springs and a discharge plate. The press mold is a circular plate structure, and a guiding positioning shaft head is arranged in the center of the circular plate structure; riveting and pressing ribs are arranged on the periphery of the guiding positioning shaft head; the discharge plate is a circular plate structure, the diameter of the circular plate structure is identical to that of the press mold, and a through hole is disposed in the center of the discharge plate; and a plurality of disc spring mounting grooves are arranged on the plate structure of the discharge plate and the plate structure of the press mold, each ejector rod is mounted in the center of the corresponding disc spring mounting groove, the disc springs are strung on the ejector rods, one end of each ejector rod is fixedly connected with the press mold, a flange is disposed at the other end of the ejector rod, the discharge plate is limited and can axially move along the ejector rod. The bearing riveting and pressing tool has functions of guiding, positioning, riveting, pressing, discharging and the like, is simple in structure as compared with an existing bearing riveting and pressing mold, workers operate the bearing riveting and pressing tool conveniently, materials are discharge easily, timely and accurately, and work efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a tooling for bearing riveting. Background technique [0002] The bearing assembly is an important supporting component of various equipment connections. After the bearing is riveted, it must meet the positioning accuracy requirements and rotate flexibly. In the existing riveting process, the workpiece is put into the positioning sleeve on the workbench after being loaded into the bearing, and the upper die is riveted around to complete the riveting work of the bearing. There are two ways of riveting the upper die: the first In order to use the split upper die method for riveting, the upper die is composed of an upper template, a positioning shaft (material 45 steel, quenched and tempered) and four riveting pins (material T10A, quenched). The disadvantage of die riveting is that the riveting pin is very small, and the material is brittle after quenching, and the se...
