Synchronous positioning and press-fitting device for multi-station rear axle bearing

Abstract

The invention discloses a synchronous positioning and press-fitting device for a multi-station rear axle bearing. The synchronous positioning and press-fitting device for the multi-station rear axle bearing comprises a working table and a rear axle mold, wherein the rear axle mold comprises a plurality of bearing seats; bearings to be pressed are arranged in the bearing seats; pressurizing oil cylinders are arranged at least one side of two side surfaces in the axial direction of each bearing seat; each pressurizing oil cylinder comprises an oil cylinder shell and a pressurizing piston rod; apressurizing block is arranged at one outward end of each pressurizing piston rod; a positioning assembly is arranged under each bearing seat; a feeding and blanking mechanism is arranged on the upperside surface of the working table, and comprises a power mechanism; and a positioning mold capable of supporting the rear axle mold is arranged above the power mechanism. The synchronous positioningand press-fitting device for the multi-station rear axle bearing provided by the invention has the advantages that the rear axle mold is convenient and safe to feed and blank; the bearing is pressed in a horizontal plane, so that the processing space is large, no repetitive positioning is needed, the positioning times is less, and the pressing-fit efficiency is high; and the feeding and blanking mechanism can be used for pre-positioning the rear axle mold, so that the bearing can be processed and positioned conveniently and can be quickly pressed.

Description

technical field [0001] The invention relates to the technical field of bearing pressing, in particular to a multi-station rear axle bearing synchronous positioning and pressing equipment. Background technique [0002] The conventional technology of rear axle bearings of automobiles usually adopts vertical punching, and the bearing is placed above the bearing seat. However, due to the axisymmetric structure of the rear axle, there are usually four bearing seats for installing bearings on the rear axle. The two groups are located on the same axis, and the axes of the two sets of bearing housings are parallel. Due to the structural interference of the rear axle when the bearing is pressed on the punch press, it is easy to cause misalignment of the bearing installation, affecting the accurate installation of the rear axle bearing, and even causing serious problems. The rear axle is broken or distorted, which poses a safety hazard; due to the large size and irregular shape of the...
