An Adaptive Fully Automatic Rapid Track Change System

Abstract

The invention discloses a self-adaptive full-automatic quick rail change system. Two rail change execution assemblies placed oppositely are installed on the same rail change rotary table, two rail change execution assemblies arranged in parallel relatively are installed on a guide rail section set on the same side, and a rail change drive assembly and an advancing drive assembly are installed on the same side of a chassis. The advancing drive assembly transmits power to the rail change execution assemblies through a unilateral synchronous cog belt, and the rail change drive assembly transmitspower to the rail change execution assemblies through a bilateral synchronous cog belt. In the initial state, the rail change rotary tables and multiple guide rail sections in a guide rail assembly are connected and matched, so that a continuous rail is formed. In the working process, the two rail change execution assemblies perpendicular to the advancing direction turn 90 degrees in the oppositedirections, rail change guide rails on the rail change rotary tables are driven to rotate at 90 degrees, butt joint of the rail change guide rails in the guide rail vertical direction is finished, andtherefore a right-angle rail change action is finished.

Description

technical field [0001] The invention relates to an adaptive full-automatic fast track changing system. The system is especially suitable for the track change between parallel tracks in a small area and in a narrow space. It has strong self-adaptive ability and can be applied to both flat and curved surfaces. Background technique [0002] At present, the connection of fastening holes is an important part of aircraft assembly and manufacturing. Due to the large size, complex shape, and large number of parts and connectors, the labor of aircraft assembly accounts for about half or more of the total labor of aircraft manufacturing. At present, the fastening holes on the aircraft skin are processed manually. When the workers process the riveting holes, they fix the drilling template on the part to be processed, and use the hand drill to sequentially process along the inherent direction of the drilling template. With this processing method, the level of hole making is affected by...

Problems solved by technology

At present, the fastening holes on the aircraft skin are processed manually. When the workers process the riveting holes, they fix the drilling template on the part to be processed, and use the hand drill to sequentially process along the inherent direction of the drilling template. With this processing method, the level of hole making is affected by the narrow curved surface space on the one hand, and the worker's technology on the other hand. The quality of hole making is uneven, and the assembly accuracy cannot be guaranteed, which makes the stability of the final product poor, and the quality of its assembly connection is directly affected. It affects the anti-fatigue performance and reliability of the product structure, and the efficiency of hole making is low, which affects the assembly efficiency of the aircraft
