Electric multiple unit chassis equipment pre-assembly tool and method

Abstract

The invention discloses an electric multiple unit chassis equipment pre-assembly tool. The electric multiple unit chassis equipment pre-assembly tool comprises a rigid platform, a plurality of longitudinal linear sliding rails parallelly arranged on the rigid platform, a first positioning mechanism and a second positioning mechanism, wherein the first positioning mechanism and the second positioning mechanism move along the longitudinal linear sliding rails. A plurality of longitudinal positioning blocks are arranged on one sides of the longitudinal linear sliding rails, and third positioningmechanisms are arranged at the two ends of the longitudinal linear sliding rails. Longitudinal connecting plates moving along the longitudinal linear sliding rails are arranged between the first positioning mechanism and the longitudinal linear sliding rails, transverse linear sliding rails are arranged on the longitudinal connecting plates, and the first positioning mechanism moves along the transverse linear sliding rails. A fine adjustment mechanism is further arranged at one end of the rigid platform, and the problems that the floor space of the chassis equipment pre-assembly tool is large, vehicle model conversion attachments are more, the workload is large and the working efficiency is low are solved. The invention further discloses an electric multiple unit chassis equipment pre-assembly method. A modular assembly method is adopted, and the electric multiple unit chassis equipment pre-assembly method has the characteristics of fast assembly and scattered processes.

Description

technical field [0001] The invention belongs to the field of railway electric train unit manufacturing, and in particular relates to a pre-assembly tool and method for electric train unit underframe equipment. Background technique [0002] In the context of the current leap-forward development of railways, the speed, safety and comfort of the railway electric multiple units with dispersed power have been greatly improved compared with the railway passenger cars with concentrated traction power. The technical requirements are also getting higher and higher. Such as Figure 6 As shown, it is a schematic diagram of the structure of the underframe equipment of the EMU. At present, the underframe equipment of the EMU adopts modular production, mainly including installation beams, various equipment parts, various types of gas pipelines, power cables and trunking, etc. composition. There are two types of EMUs: 8-group and 16-group. For the composition of EMU chassis equipment, 8-...
