Anti-side-rolling torsion bar assembly automatic positioning and assembling device and method

Abstract

The invention discloses an anti-side-rolling torsion bar assembly automatic positioning and assembling device and method. The anti-side-rolling torsion bar assembly automatic positioning and assembling device comprises a rack, a table board, a table board displacement mechanism, an automatic clamping device, an automatic centering device, a control system, an assembly limiting device, circumferential positioning blocks and a mechanical arm mounted on the rack. The mechanical arm is used for transferring a torsion bar shaft to a preset position; the automatic centering device is used for conducting automatic centering on the torsion bar shaft; the automatic clamping device is used for conducting automatic clamping and positioning on the torsion bar shaft; the assembly limiting device is used for automatically positioning torsion arms and assembling limiting check blocks so as to assemble the torsion arms onto the torsion bar shaft. The anti-side-rolling torsion bar assembly automatic positioning and assembling device can realize automatic centering and automatic clamping of the torsion bar shaft on an assembly platform, realize automatic positioning to assemble the limiting check blocks (namely, positioning check blocks) and automatically release clamping after completion of assembly of a hot jacket. The anti-side-rolling torsion bar assembly automatic positioning and assemblingdevice conducts coordinate positioning through grating rulers, and the assembly precision and efficiency of the assembly platform are improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle anti-rolling torsion bar system manufacturing. Background technique [0002] During the assembly process of the anti-roll torsion bar system, after the torsion arm needs to be heated to the temperature required by the process, the inner hole is expanded to the size required for assembly, and the two ends of the torsion bar shaft are shrunk and assembled, and the torsion bar assembly is cooled. Later, an interference fit will be formed. In order to ensure the correct position of the torsion arm and the torsion bar shaft after shrink fit, the torsion bar shaft must be positioned before assembly. During the shrink fit assembly, the axial position and the circumferential position of the torsion arm are guaranteed by the tooling limit. [0003] The assembly table in the existing process needs to adjust the relative position of the tooling before each product change, and manual measurement is requ...
