Description

Multi-dimensional adjustable fixture single-section flexible construction system

Technical Field

The invention relates to a single-section precise coordinate positioning construction of a vehicle's real-proportion appearance and interior flexible modeling in the field of automobile production, and specifically, it relates to a multi-dimensional adjustable fixture single-section flexible construction system.

Background technique

Rail transit has become one of the main means of transportation for people's daily travel with its fast, safe and convenient transportation mode, especially high-speed rail has developed rapidly. However, with the increasing number of domestic and international orders for high-speed rail, the defects of vehicle modeling have also been exposed. Rail vehicles are welded with metal materials such as steel and aluminum alloy, and once formed, they cannot be changed. However, before forming, it is difficult to fully and truly feel the interior and exterior appearance of the car body, the layout of the control system, the degree of ergonomic coordination, etc. based on the design stereogram. If the vehicle is changed after forming, it will cause huge economic losses. An appropriate solution is to establish a flexible modeling system for rail vehicles, which fully simulates the interior and exterior modeling and control layout of rail vehicles, and conducts ergonomic design. The opinions raised by customers can be quickly changed, and all flexible parts can be reused until the customer is satisfied. Then make the actual car body, which can avoid huge economic losses and create more benefits.

This rail vehicle flexible modeling system is mainly composed of an installation platform, a flexible rigid frame (the main body is an aluminum alloy profile and a metal hinge with adjustable angle), vehicle accessories, and interior and exterior trim panels. The installation platform is the floor plane inside the vehicle, and is also the foundation for the flexible rigid frame. It is composed of aluminum alloy profiles and lower supports; the flexible rigid frame is based on aluminum alloy profiles, and adopts specific connection fixtures and metal hinges that can be adjusted and positioned at any angle. The installation position of the coordinate positioning device is reserved on these flexible components. The interior and exterior trim panels are designed according to the interior and exterior shapes of the vehicle body. Reusable composite materials are used through molding and processing methods to obtain decorative panels that are consistent with the design shape and have the same size as the panels divided by the interior and exterior decoration of the real vehicle, and have installation connection points at the set position; such interior and exterior trim panels are installed on the flexible rigid frame through precise coordinate positioning, and the real vehicle interior and exterior shape appearance is obtained; then the vehicle accessories including lights, windshields, interior lighting, front control consoles, etc. are installed at the design position, forming a real vehicle simulation appearance of the overall appearance, control and other ergonomic designs of the real vehicle. Improve the design according to customer needs and readjust the assembly until the customer is satisfied. If the real vehicle is produced and then modified, the cost will be tens of millions. However, using this rail vehicle flexible modeling system, the cost of modification is only about 0.5% of the real vehicle modification, and the economic benefits are obvious.

The cross-sectional decomposition is adopted, and the section frame is roughly formed with standard aluminum profiles, and the coordinate point positioning parts can be fixed on the frame; the exterior interior panels are divided according to the design grid and processed and formed with light materials; each exterior interior panel after division has a strong magnetic ring built in the predetermined coordinate point; the exterior interior panels are installed correspondingly with the coordinate positioning parts on each section frame to form a flexible real-scale simulated rail vehicle model, and then the vehicle accessories including lights, windshields, interior lighting, front control consoles, etc. are installed at the designed position, forming a real vehicle simulation look and feel with ergonomic design such as the overall appearance and control of the real vehicle. Therefore, the first problem to be solved is the installation of single-section coordinate positioning parts. There are many coordinate points to be positioned, so the positioning fixture is required to be both accurate and easy to operate. At present, no flexible modeling system directly applied to rail vehicles has been found in domestic and foreign information.

Summary of the invention

1. Use the ball rod as the coordinate positioning part, the center of the ball is the predetermined coordinate point, and part of the rod is used for fixed position, and further automatic installation is considered while accurately positioning;
