A high-efficiency press-fitting equipment for rear axle bearings

Abstract

The invention discloses efficient rear axle bearing press fitting equipment which comprises a working table and a rear axle die. The rear axle die comprises a plurality of bearing blocks, to-be-pressed bearings are arranged in the bearing blocks, at least one of the two axial side faces of each bearing block is provided with a pressure applying oil cylinder, and each pressure applying oil cylindercomprises an oil cylinder shell and a piston rod; the outward end of each piston rod is provided with a pressure applying block attached to the side face of the corresponding to-be-pressed bearing, the axis of each to-be-pressed bearing is parallel to a working upper plane of the working table, and the working table is provided with a limiting assembly and a positioning assembly for positioning the rear axle die; and the pressure applying oil cylinders are fixed to the limiting assembly, and the pressure applying blocks can do spiral motion relative to the axes of the piston rods. The efficient rear axle bearing press fitting equipment has the beneficial effects that the to-be-pressed bearings ate subject to in-plane pressure applying machining rather than longitudinal punching machining,the machining space is increased, positioning and machining are convenient, and the working efficiency of the pressed bearings is improved; and the pressure applying blocks are pressed into the to-be-pressed bearings while rotating relative to the bearing blocks, stress concentration of the surfaces of the to-be-pressed bearings is prevented, the installing strength of the to-be-pressed bearingsis improved, and the positioning requirement is low.

Description

technical field [0001] The invention relates to the technical field of bearing pressing, in particular to an efficient rear axle bearing pressing equipment. Background technique [0002] The rear axle refers to the rear drive shaft component of the vehicle power transmission, and is also a device used to support the wheels and connect the rear wheels. Bearings need to be installed in the rear axle, usually punched by a vertical punch. Usually the rear axle has an axisymmetric structure, and there are usually four bearing seats on the rear axle, two of which are on the same axis, and the other two are also on the same axis, and the axes of the two sets of bearing seats Parallel, due to the misalignment of the bearing installation when the bearing is pressed on the punch press, it will affect the accurate installation of the rear axle bearing, and even cause the rear axle to break or twist in severe cases, resulting in potential safety hazards; due to the interference of the ...
