Description
Technical Field
The invention relates to the field of automobile production, in particular to a single-section accurate coordinate positioning and building system for a real-proportion shape and an interior flexible shape of a vehicle, and particularly relates to a multi-dimensional adjustable fixture single-section flexible building system.
Background
The rail transit becomes one of the main transportation means for people to go out daily in a fast, safe and convenient transportation mode, and particularly, the rapid development of high-speed rails also exposes the defect of vehicle modeling along with the increasing domestic and international orders of the high-speed rails. The rail vehicle is formed by welding metal materials such as steel, aluminum alloy and the like, and once formed, the rail vehicle can not be changed. Before the vehicle is not formed, the appearance of the inside and outside of the vehicle body, the layout of a control system, the coordination degree of ergonomics and the like are difficult to be comprehensively and really sensed only by designing a stereogram. If the vehicle after shaping changes, can cause huge economic loss. One suitable solution is to create a flexible modeling system for a rail vehicle that fully and realistically simulates the internal and external modeling and the control arrangement of the rail vehicle and is ergonomically designed. The opinion presented to the customer can be changed quickly and all flexible parts can be reused until the customer is satisfied. Then, the vehicle body is manufactured for practical use, so that huge economic loss can be avoided, and more benefits are created.
The flexible modeling system of the railway vehicle mainly comprises a mounting platform, a flexible rigid framework (a main body is an aluminum alloy section and a metal hinge with a settable angle), vehicle accessories and inner and outer decorative plates. The mounting platform is an in-vehicle floor plane, also builds a foundation for the flexible rigid framework, and consists of an aluminum alloy section and a lower support; the flexible rigid framework is formed by taking an aluminum alloy section as a backbone, adopting a specific connecting clamp and a metal hinge which can be adjusted in angle and positioned at any angle, and the flexible components are provided with installation positions of coordinate positioning devices. The inner and outer decorative plates are decorative plates which are obtained according to the design shape of the vehicle body by using a recyclable composite material through forming and processing means and correspond to the size of plates divided by the real vehicle inner and outer decorations, and installation connecting points are arranged at set positions; the inside and outside decorative plates are accurately positioned and installed on the flexible rigid framework through coordinates, so that the appearance and the impression of the inside and the outside shapes of the real vehicle are obtained; then, the car accessories including lamplight, windshield glass, in-car lighting, a car head console and the like are arranged at the designed positions, so that the real car simulation impression of ergonomics design such as the integral appearance, the control and the like of the real car is formed. The design is modified according to customer needs and the assembly is readjusted until the customer is satisfied. If the vehicle is transformed after being produced, the cost is in the level of ten million. By using the flexible modeling system of the railway vehicle, the reconstruction cost is about 0.5 percent of the reconstruction cost of the real vehicle, and the economic benefit is obvious.
Adopting transverse multi-section decomposition, roughly forming a section frame by using a standard aluminum profile, and fixing a coordinate point positioning piece on the frame; the appearance interior trimming panel is divided according to the design drawing grids and is processed and formed by light materials; a powerful magnetic ring is arranged in each divided appearance interior trimming panel at a preset coordinate point; the appearance interior trim panel and the coordinate positioning piece on each section frame are correspondingly installed to form a flexible real-proportion simulated rail vehicle model, and vehicle accessories including lamplight, windshield glass, interior lighting, a headstock console and the like are installed at design positions, so that the real vehicle simulated impression of ergonomics design such as the integral appearance, the control and the like of a real vehicle is formed. Therefore, the problem to be solved is that the single-section coordinate positioning piece is installed, and the number of coordinate points to be positioned is large, so that the positioning fixture is required to be accurate in positioning and simple to operate. At present, no flexible modeling system directly applied to rail vehicles is found in domestic and foreign data.
