Tool and method for assembling of carbon fiber composite cross beams of standardized CRH train equipment compartment

Abstract

The invention provides a tool and method for assembling of carbon fiber composite cross beams of a standardized CRH train equipment compartment. The tool for the assembling of the carbon fiber composite cross beams of the standardized CRH train equipment compartment comprises a base platform, a positioning press plate, a piece of end seal foam, side portion balance plates and a top balance plate; bolt holes are formed in the positioning press plate and the base platform correspondingly; the positioning press plate is connected to the top surface of the base platform through bolts; one or more limit holes are formed in the top surface of the base platform; limit blocks are arranged in the limit holes; and the end seal foam, the side portion balance plate and the top balance plate are arranged between the positioning plate and the base platform correspondingly. The tool is a novel practical tool formed by machining and combining with the steel serving as the raw material. The tool for the assembling of the carbon fiber composite cross beams of the standardized CRH train equipment compartment has the advantages of being simple in structure, easy to manufacture, easy to implement, low in manufacturing cost, high in assembling precision and the like. The assembling precision of structural elements is guaranteed, the manufacturing cost is greatly lowered, and the manufacturing cycle is greatly shortened at the same time.

Description

technical field [0001] The invention relates to a tooling and method for assembling a carbon fiber composite crossbeam in a standardized EMU equipment compartment, and is particularly suitable for assembling a carbon fiber composite crossbeam in an equipment compartment of a standardized EMU in China.
