Tool and method for assembling anti-rolling torsion bars with various sizes

Abstract

The invention discloses a tool and a method for assembling anti-rolling torsion bars with various sizes. The tool comprises a support and a workbench arranged on the support, and is characterized by further comprising a support seat, arc-shaped washers and height positioning blocks, the support seat which can slide or can be fixed is arranged on the workbench, and comprises fixing devices, a base and positioning barriers, the fixing devices are used for fixing a shaft of a torsion bar, the positioning barriers are arranged on sides of the support seat, the height positioning blocks are used for positioning torsion arms with a certain relative height deviation, and the arc-shaped washers and the fixing devices of the support seat are matched with one another to fix the shaft of the torsion bar. The tool and the method for assembling the anti-rolling torsion bars have the advantages that the tool is convenient to operate and low in cost, and is simple and practical, the distance from the support seat to the workbench can be adjusted according to the distance between the torsion arms with different sizes, and accordingly the assembly precision of the torsion arms can be guaranteed; the arc-shaped washers can be determined according to shafts of the torsion bars with the different sizes; and the tool with the structure can be used for assembling the anti-rolling torsion bars with the various sizes.

Description

technical field [0001] The invention relates to an assembling tool and an assembling method of an anti-rolling torsion bar, in particular to an assembling tool and an assembling method of an anti-rolling torsion bar for a rail vehicle. Background technique [0002] With the development of rail transportation, the speed of rail vehicles is getting faster and faster. The role of the anti-roll torsion bar system to improve the roll stiffness of the vehicle is becoming more and more important. It has become an essential device for subways and high-speed trains. The anti-roll torsion bar is the core component of the device, and its assembly accuracy directly affects the performance of the entire device. [0003] The anti-roll torsion bar generally includes a torsion bar shaft, two torsion arms (such as figure 1 As shown), in order to limit the relative movement between the torsion bar shaft and the torsion arm, the connection between the torsion bar shaft and the torsion arm mai...

AI Technical Summary

Problems solved by technology

The anti-roll torsion bar has various specifications, the distance between the two torsion arms is different, the diameter of the torsion bar shaft is different, etc. If there is no general assembly tool to assemble the anti-roll torsion bar of different specifications, then the assembly it will be very troublesome
