High-speed train first train body assembling device and assembling method thereof

Abstract

The invention discloses a high-speed train first train body assembling device and an assembling method thereof, and belongs to the field of welding, assembling and auxiliary positioning devices for train first train bodies. The device comprises a train roof assembling tool, a front window frame positioning tool, a train roof hoisting tool, a side wall assembling tool and a train body front end plate assembling tool; train roof assembling and welding are completed through the train roof assembling tool; train body front end plates are located at the standard positions of the end of the side wall assembling tool through the train body front end plate assembling tool; and positioning operation of train roofs and the side wall assembling tool is completed through the train roof hoisting tool and the front window frame positioning tool. According to the high-speed train first train body assembling device and an assembling method thereof, the train roofs can be assembled, welded and machinedon the ground through the train roof assembling tool, the positioning efficiency and the assembling precision of all parts of the train roofs both can be significantly improved, then the symmetry ofthe central vertical plane of the train roofs is significantly improved, therefore, the wind resistance and waggling and noise which are generated when a train runs at high speed can be significantlyreduced, the mechanical transmission path can be optimized, and the structural strength of a train body is further improved.

Description

technical field [0001] The invention belongs to the field of auxiliary positioning devices for welding and pairing of a head car body of a train, and in particular relates to a pairing device and a method for combining a car body of a high-speed train. Background technique [0002] The vertical plane is a vertical plane passing through the central axis of the bottom surface of the geometric body, which refers to the section that can divide the symmetrical geometric body into two parts of mirror symmetry along the vertical direction. [0003] Such as Figure 1 to Figure 4 As shown, the car body 1 of a head car of a certain type of high-speed train mainly includes a roof 1-1, a left side wall 1-2 and a right side wall 1-3 which are mirror images of each other, and a front end plate 1-4 of the car body, wherein , the exterior of the roof 1-1 and the front end of the side wall are large curved parts with a bullet-shaped streamlined appearance, and the roof 1-1 includes a roof pa...

Problems solved by technology

[0013] In order to solve the problem of difficult control of the positioning accuracy and unreasonable assembly sequence in the existing car body composite welding method based on sling hoisting, the size of the car body of the head car is easily out of tolerance, the quality of welding operation and the safety of the operation cannot be guaranteed, and even the car body may be damaged. The vertical surface of the roof and the vertical surface of the side wall are not uniform, which seriously affects the technical problem of symmetry and structural strength. The present invention provides a high-speed train head car body assembly device and its assembly method
