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

Embodiment Construction

[0057] figure 1 for the overall schematic. As shown in the figure, it mainly includes rail vehicle aluminum profile self-positioning handling equipment I, closed-loop grinding control system II, ground III, rail vehicle side wall hollow extruded aluminum alloy profile combination IV, self-positioning device V, aluminum profile grinding and positioning clip Tight tooling Ⅵ and aluminum profile automatic assembly and welding positive and negative flip tooling Ⅶ.

[0058] figure 2 Flow chart of manufacturing process for rail vehicle body side walls. As shown in the figure, the first step of the traditional side wall manufacturing process is: using a hoisting device to pick up the hollow extruded aluminum alloy profile that has been grooved from the material rack and lift the aluminum profile grinding tool; the second step of the process is: : Grinding the groove of the hollow extruded aluminum alloy profile with oxide film; the third step of the process is: use a hoisting dev...

Abstract

The invention provides a self-positioning grinding tool for an aluminum profile of a rail vehicle, including a positioning platform, a supporting platform and a clamping platform used in conjunction; The first positioning device and the second positioning device on the device; the first positioning device includes a first self-positioning seat; the second positioning device includes a second self-positioning seat and a clamping device installed on the side of the second self-positioning seat, The second self-positioning seat is inserted into the first self-positioning seat; the supporting platform is installed on the bottom of the aluminum profile of the rail vehicle; the clamping platform is installed on the bottom of the aluminum profile of the rail vehicle, on one side of the clamping platform There is a clamping device for clamping the aluminum profile of the vehicle.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a self-positioning grinding tool for aluminum profiles of rail vehicles. Background technique [0002] At present, in order to achieve the design speed of high-speed trains, and at the same time to reduce wheel and rail wear, reduce energy consumption, reduce the load of the braking system and other requirements, so the body structure needs to use lightweight materials, and aluminum alloy tensile profiles are just enough Meet the body strength and rigidity requirements. The rail vehicle body composed of hollow extruded aluminum alloy profiles includes four major components, the bottom frame, end wall, side wall and 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 the same time, the sid...
