Rail vehicle aluminum profile self-positioning polishing tool

Abstract

The invention provides a rail vehicle aluminum profile self-positioning polishing tool. The rail vehicle aluminum profile self-positioning polishing tool comprises positioning platforms, supporting platforms and clamping platforms which are used in cooperation. The positioning platforms are installed at the two ends of a rail vehicle aluminum profile and comprise supporting platforms, first positioning devices and second positioning devices; the first positioning devices and the second positioning devices are placed on the supporting platforms; the first positioning devices comprise first self-positioning seats; the second positioning devices comprise second self-positioning seats and clamping devices installed on the side faces of the second self-positioning seats, and the second self-positioning seats are inserted into the first self-positioning seats; the supporting platforms are installed at the bottom of the rail vehicle aluminum profile; and the clamping platforms are installed at the bottom of the rail vehicle aluminum profile, and a clamping device used for clamping the vehicle aluminum profile is arranged on one side of each clamping platform.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a self-positioning and grinding tool for rail vehicle aluminum profiles. Background technique [0002] At present, in order to achieve the design speed of high-speed trains, at the same time, it is necessary to reduce wheel and rail wear, reduce energy consumption, and reduce the load of the braking system. Therefore, the car body structure needs to use lightweight materials, and aluminum alloy tensile profiles can just Meet the strength and rigidity requirements of the car body. The rail vehicle body composed of hollow extruded aluminum alloy profiles includes four major components, the underframe, the end wall, the side wall and the roof, all of which are integrally welded by MIG welding. As one of them, the welding quality of the side wall is directly related to whether the final structure of the car body can meet the design and use requirements. At th...

AI Technical Summary

Problems solved by technology

For the traditional process of assembling side wall profiles, five profiles are hoisted in turn by the crane and placed in the assembly station. However, due to changes in the assembly datum during assembly and manual assisted assembly, there will be assembly errors and it will take Time to make adjustments to assembled profiles

If the error is not eliminated, the uniformity of the weld will be affected in the subsequent welding, thereby reducing the overall structural strength of the side wall, and serious accidents of structural damage to the vehicle body will occur when the vehicle is running
