Abstract

The invention discloses a disassembly and assembly tool and method for a detachable interference fit anti-rolling torsion bar. The disassembly and assembly tool includes a bracket and a bottom plate installed on the bracket; the disassembly and assembly tool also includes a pressure output assembly and a support seat assembly , baffle plate assembly, torsion bar shaft pressure head assembly, torsion arm pressure head assembly; the pressure output assembly is installed on the left end part of the bottom plate, the support seat assembly is installed on the middle part of the bottom plate, and the baffle plate assembly is installed on the right end part of the bottom plate. The support seat assembly is used to fix or place the torsion bar shaft; the ultra-high pressure power supply facility is used to provide hydraulic pressure and transmit it to the inner hole of the torsion arm through the high-pressure oil pipe, and at the same time, apply axial pressure to the torsion arm or torsion bar shaft through the pressure output assembly, thereby Realize the assembly or disassembly of the torsion arm and the torsion bar shaft. The invention does not need to fasten the fastening parts, and does not need to carry out thermal assembly or cooling treatment, does not need an oven to heat the torsion arm, and does not need to carry out cooling treatment after assembly, which improves the assembly efficiency.

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...
