Disassembling and assembling tool and method for detachable interference fit anti-roll torsion bar

Abstract

The invention discloses a disassembling and assembling tool and method for a detachable interference fit anti-roll torsion bar. The disassembling and assembling tool comprises a support and a bottom plate, wherein the bottom plate is arranged on the upper surface of the support; the disassembling and assembling tool further comprises a pressure output assembly, a supporting base assembly, a baffleplate assembly, a torsion rod shaft pressure head assembly and a torsion arm pressure head assembly; the pressure output assembly is arranged at the left end part of the upper surface of the bottom plate, the supporting base assembly is arranged in the middle of the upper surface of the bottom plate, and the baffle plate assembly is arranged at the right end part of the upper surface of the bottom plate. A supporting base assembly is adopted to fix or place a torsion rod shaft, the ultrahigh-pressure power supply facility is used for providing hydraulic pressure and transmitting the hydraulicpressure to the inner hole of a torsion arm through a high-pressure oil pipe, meanwhile, axial pressure is applied to the torsion arm or the torsion bar shaft through the pressure output assembly, sothat the torsion arm and the torsion bar shaft can be assembled or disassembled. According to the disassembling and assembling tool and method, fastening of fastening parts is not needed, heat assembly or cooling treatment is not needed, the torsion arm does not need to be heated by a drying oven, cooling treatment is not needed after assembly, and assembly efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of disassembly and assembly of an anti-rolling torsion bar. Background technique [0002] At present, for the anti-roll torsion bar with cone interference fit, the most widely used assembly method is mainly the thermal assembly method. The tooling of the thermal assembly scheme is mainly composed of an oven, an assembly platform, a positioning device and a circumferential positioning block. The oven is used to heat the torsion arm, and the positioning device is used to position the torsion arm during assembly. Its assembly process: put the torsion arm into the oven for heat treatment, and fix the position of the torsion bar shaft; after the torsion arm is heated to the required temperature, take out the torsion arm, assemble the torsion arm to the torsion bar shaft, and pass through the positioning device and the circumferential direction. The role of the positioning block ensures the center distance betwe...
