A multi-station synchronous rear axle bearing pressing equipment

Abstract

The invention discloses a multi-station synchronous rear axle bearing press-fitting device. The device comprises a workbench and a rear axle die, the rear axle die comprises a plurality of bearing seats, the bearing seats are internally provided with to-be-pressed bearings, at least one side of the two axial side faces of each bearing seat is provided with a pressure applying oil cylinder, each pressure applying oil cylinder comprises an oil cylinder shell and a piston rod, pressure applying blocks attached to the side faces of the to-be-pressed bearings are arranged at the ends, facing outwards, of the piston rods, the piston rods are coaxial with the to-be-pressed bearings, the axis of each to-be-pressed bearing is parallel to the working upper plane of the workbench, a limiting assemblyand a positioning assembly for positioning the rear axle die are arranged on the workbench, and the pressure applying oil cylinders are fixed on the limiting assembly. The device has the advantages that when re-machining is carried out after pre-positioning, fixing of the rear axle die is completed by the pressure applying oil cylinders and the pressure applying blocks, the machining space is enlarged, positioning and machining are convenient, the machining precision of the to-be-pressed bearings and the bearing seats is improved, the to-be-pressed bearings are prevented from being eccentricto the bearing seats, the plurality of to-be-pressed bearings can be synchronously machined through the pressure applying oil cylinders, so that the working efficiency of bearing press-fitting is improved.

Description

technical field [0001] The invention relates to the technical field of bearing pressing, in particular to a multi-station synchronous rear axle bearing pressing equipment. Background technique [0002] The rear axle bearings of automobiles need to be installed with interference. In conventional technology, punching is usually used. However, due to the axisymmetric structure of the rear axle, there are usually four bearing seats for installing bearings on the rear axle, two of which are The seat is located on the same axis, and the other two bearing seats are also located on the same axis, and the axes of the two sets of bearing seats are parallel. Due to structural interference when the bearing is pressed on the punch press, it is easy to cause misalignment of the bearing installation and affect the accurate installation of the rear axle bearing. In severe cases, it may even cause the rear axle to break or twist, causing potential safety hazards; due to the interference of t...
