Description

Technical Field

[0001] The invention relates to the technical field of EMU maintenance, and in particular to a hot-installation tool and a hot-installation method for a bogie anti-roll torsion bar connecting bushing. Background Art

[0002] As a component of the EMU bogie bolster, the anti-roll torsion bar reduces the outward tilt angle of the body when passing through a curve through the torsion bar (torsion spring). In this way, the anti-roll torsion bar can ensure the specified distance from the ground and improve the comfort of the ride. The anti-roll torsion bar needs to be removed from the frame for inspection and repair. Among them, the third and fourth level repairs require the replacement of the connecting bushing at the end of the rod.

[0003] In the current industry, the bogie anti-roll torsion bar and the corresponding connecting bushing need to be manually aligned and installed, and the operation mainly relies on manual alignment. The bushing needs to be heated during the installation process, but the temperature drops rapidly during the manual assembly process, and the bushing cools down too quickly. Therefore, the installation time is extremely short, and high skills are required for the installer. At the same time, when the bushing is hot-installed, the material is easily deformed when heated, and manual alignment is used. This process cannot guarantee the coaxiality of the bushing and the rod, and the connecting bushing is prone to tilt during installation, resulting in a low hot installation pass rate, a long rework time, low maintenance efficiency and low quality.

The vertical adjustment component is connected to the universal ball head through the through holes.

8. The shrink fitting tool for the bogie anti-roll torsion bar connecting bushing according to claim 7, characterized in that: The first horizontal adjustment guide rail and the second horizontal adjustment guide rail both extend horizontally, and the extension directions of the first horizontal adjustment guide rail and the second horizontal adjustment guide rail are vertically arranged.

9. The shrink fitting tool for the bogie anti-roll torsion bar connecting bushing according to claim 8, characterized in that: The vertical adjustment assembly includes a fixed block and an adjustment rod, wherein the fixed block is fixedly arranged on the second adjustment platform, the adjustment rod is threadedly connected to the fixed block, and the adjustment rod is vertically arranged, and the top end of the adjustment rod is fixedly connected to the universal ball head.

10. A method for hot-installing a bogie anti-roll torsion bar connecting bushing, characterized in that: The hot-loading tool for the bogie anti-roll torsion bar connecting bushing according to any one of claims 3 to 9 comprises the following steps: S1, preparation stage; Placing the bogie anti-roll torsion bar to be assembled at an assembly station; S2, installation phase; The positioning part is placed on the bogie anti-roll torsion bar to be assembled, so that the first guide groove and the second guide groove are clamped and fixed on the bogie anti-roll torsion bar, and the position of the clamping plate is adjusted so that the positioning part clamps the rocker arm, and the coaxiality of the positioning part and the bogie anti-roll torsion bar is within the standard range; S3, standard position acquisition phase; Take out a standard bushing and place it on the sleeve bracket, adjust the posture of the sleeve bracket until the standard bushing is aligned with the bogie anti-roll torsion bar to be assembled, select the thickness of the limit washer so that the standard bushing is installed in the standard position of the bogie anti-roll torsion bar, and after assembling the standard bushing, move the sleeve bracket back and forth along the axial direction of the bogie anti-roll torsion bar. If there is no jamming during the process, fix the posture of the sleeve bracket by the first locking member and the second locking member, take out the standard bushing, and put it back to its original position; S4, liner assembly stage; Take out the connecting bushing to be assembled, heat the connecting bushing to 500° C., take out the heated connecting bushing and quickly place it on the sleeve bracket, move the sleeve bracket axially along the bogie anti-roll torsion bar to sleeve the connecting bushing on the bogie anti-roll torsion bar and push it until it contacts the pad, and wait until the temperature of the connecting bushing drops to room temperature; S5, verification stage; Check the assembly status. If the assembly is qualified, it will be marked as qualified and sent to the next workstation. If the assembly is unqualified, the installed bushing will be removed and reworked.
