Embodiment Construction

[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] see figure 1 , the present invention provides a trinity of aluminum weldments, TC-end vehicle body traction pillow assembly welding process, the vehicle body traction pillow consists of a bolster beam, a traction beam and a coupler mounting seat. The upper plane of the corbel is connected to the floor, the lower plane is assembled with the bogie, the two sides of the corbel are welded to the side beams on both sides, the traction beam plays the role of traction during the operation of the vehicle, the mounting hole on the coupler mounting seat is assembled with the coupler, and the side Assemble with cab.

[0032] In this example, if figure 2 As shown, the corbel, traction beam and coupler mounting seat are all made of aluminum alloy mat...

Abstract

The invention discloses a vehicle body draft, bolster and buffer assembling and welding process. The vehicle body draft, bolster and buffer comprises a body bolster, a draft sill and a coupler mounting base which are all made of aluminium alloy materials. The process comprises the following steps: (A) assembling and welding the coupler mounting base; (B) assembling and welding the draft sill and a cover plate; (C) assembling and welding the components of a body bolster plate; and (D) carrying out assembling and welding on a general assembly equipment: assembling and welding the coupler mounting base, the draft sill and the body bolster on the general assembly equipment; dispensing with machining and ensuring the flatness to be 0.5mm after completing welding; ensuring the verticality between the coupler mounting surface and the air spring mounting surface to be not more than 1.5mm; and ensuring the deviation from the center of the coupler mounting base to the center of the air spring hole to be not more than +/-1mm. The process has the beneficial effects of solving the problem of assembling and welding of the aluminium alloy structures of high-speed trains, collecting the parameters of aluminium alloy welding through experiments, perfecting the aluminium alloy assembling and welding process, preventing deformation after welding and variation of the material displacement size, ensuring the product quality and reducing the production cost and energy waste.

Description

technical field [0001] The invention relates to an aluminum alloy assembling and welding product process, in particular to a material machining and assembling process of a trinity of aluminum welded parts, which is a car body tension pillow, and belongs to the field of product manufacturing technology. [0002] Background technique [0003] Aluminum alloy has the advantages of light weight, corrosion resistance, good appearance flatness, easy manufacture of complex curved surfaces, high specific strength, etc., and has been valued by the track modification industry around the world. At present, my country's rail transit is facing the development of high-speed passenger cars, subway passenger cars, light rail trains and high-speed heavy-duty trucks. The lightweight of trains is the first choice for increasing the speed of trains. Aluminum alloy materials can reduce self-weight, reduce resistance during operation, reduce energy consumption, and increase load, so the railway t...
