Description

Multi-dimensional adjustable fixture single-section flexible construction system
Technical Field
The invention relates to the field of automobile production, in particular to a single-section flexible building system of a multi-dimensional adjustable fixture, which is used for accurately positioning and building a single-section of a real proportional shape and an interior flexible modeling of a vehicle.
Background
Rail transit becomes one of the main transportation means for people to travel daily in a rapid, safe and convenient transportation mode, and particularly high-speed rail transit is rapidly developed. However, with the increasing domestic and international orders of high-speed rails, the defects of vehicle modeling are also exposed. Railway vehicles are welded from metallic materials such as steel, aluminum alloys, etc., and once formed cannot be changed. However, before the vehicle is not formed, the internal and external appearances, the layout of the control system, the degree of ergonomic coordination and the like of the vehicle body are difficult to fully and truly feel only by virtue of a design perspective view. If the molded vehicle is changed, huge economic loss is caused. One suitable solution is to build a flexible molding system for rail vehicles that fully truly simulates the interior and exterior molding and handling arrangements of rail vehicles and performs ergonomic design. The opinion presented to the customer can be quickly changed and all flexible components can be reused until the customer is satisfied. And then the actual vehicle body is manufactured, so that huge economic loss can be avoided, and more effects are created.
The flexible modeling system of the railway vehicle mainly comprises an installation platform, a flexible rigid framework (the main body is an aluminum alloy section bar and a metal hinge with a settable angle), vehicle accessories and an inner decorative plate and an outer decorative plate. The installation platform is an in-vehicle floor plane and also a foundation for constructing a flexible rigid framework, and consists of an aluminum alloy section bar and a lower support; the flexible rigid skeleton is formed by taking an aluminum alloy section bar as a main body, adopting a specific connecting clamp and a metal hinge which can be adjusted in angle and positioned at any angle, and the mounting positions of the coordinate positioning devices are reserved on the flexible members. The inner and outer decorative plates are decorative plates which are designed according to the vehicle body, are obtained by using a reusable composite material through forming and processing means, are consistent with the designed shape, correspond to the size of the plate divided by the real vehicle inner and outer decoration, and are provided with mounting connection points at set positions; the interior and exterior decorative plates are arranged on the flexible rigid framework through accurate positioning of coordinates, so that the appearance of the interior and exterior shapes of the real vehicle is obtained; and then the car accessories including lamplight, windshield glass, illumination in the car, a car head console and the like are arranged at the design position, so that the overall appearance of the real car, the simulation impression of the real car with ergonomic design such as control and the like are formed. The design is modified according to customer needs and the assembly is readjusted until customer satisfaction. If the real vehicles are rebuilt after being produced, the cost is in the tens of millions. The cost of transformation by using the flexible modeling system of the railway vehicle is about 0.5 percent of that 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 external shape inner decorative plate is divided according to the grid of the design drawing and is formed by processing light materials; each split appearance internal decorative plate is internally provided with a powerful magnetic ring at a preset coordinate point; the external internal decorative plate and the coordinate positioning piece on each section frame are correspondingly installed to form a flexible real-proportion simulation railway vehicle model, and then the vehicle accessories including lamplight, windshield glass, illumination in the vehicle, a vehicle head control table and the like are installed at the design position to form the overall appearance of the real vehicle, the simulation impression of the real vehicle with the ergonomic design such as control and the like. Therefore, the problem to be solved is that the single-section coordinate positioning piece is installed, the number of coordinate points to be positioned is numerous, and therefore the positioning fixture is required to be positioned accurately and is required to be operated simply. At present, no flexible modeling system directly applied to rail vehicles is found in domestic and foreign data.
