Pulley positioning device for part assembly of large-length vehicle

Abstract

The invention discloses a pulley positioning device for positioning the elements of long-length vehicle. Wherein, the bend head of positioning plate is mounted with a distant adjusting cut, a compress plate and a support pulley for adjusting the horizontal position of compartment top while they are distant from the outer surface of compartment; two sides at the middle part of positioning plate are independently mounted with frame positioning devices for baffling the edges of frame elements, while the lower end is mounted with a shape surface of positioning the theory shape of compartment, a cover edge cutting reticle for cutting the cover, and a inversed-L shape cut for positioning low longitudinal beam. The invention uses support pulley and the shape surface whose distant is 3mm, to position the compartment top and the compartment body, while it can adjust the open angle of compartment top via pad and realize positioning and assembling the compartment top, frame and side walls without additive assemble support. And it has lower cost, high accuracy and wider application.

Description

technical field [0001] The invention relates to a pulley positioning device used for positioning and assembling large-scale components such as a large-length vehicle, especially a maglev train car roof, a window frame assembly, and a side wall. Background technique [0002] The long-length vehicles in the prior art include the roof and side walls of trains and maglev cars, which are relatively large components. The work line that the jig needs to be assembled has a large span and few assembly surfaces. The positioning device used in assembly in the prior art has single purpose and high cost. Because the maglev train is a modern high-speed vehicle equipment with high cost and can only be produced in batches, its production cost control is very strict, and it needs less but more refined, multi-purpose devices that reduce the manufacturing cost as much as possible. In order to solve this problem, foreign maglev trains are reported to use a pulley positioning device only for p...

Problems solved by technology

[0003] The purpose of the present invention is to provide a maglev train that can reduce the manufacturing cost of the maglev vehicle and can complete the maglev train without adding other assembly frames, aiming at the disadvantages of the prior art that the large-length vehicle has few assembly surfaces, single use, and high installation cost.
