High-precision high-strength carbon fiber thin-wall pipe end face connecting structure

Abstract

The invention belongs to the technical field of positioning supports, and relates to a high-precision high-strength carbon fiber thin-wall pipe end face connecting structure. The connecting structure comprises a square pipe, a connecting piece fixed to the side wall of the square pipe and a connecting pipe fixed to the side of the square pipe through the connecting piece, and at least two rivet nuts are arranged on the square pipe. The connecting piece is provided with a fixing taper hole, the end, facing the connecting piece, of the connecting pipe is provided with an end face, and the connecting piece is fixed to the end face through a plurality of reverse screws embedded into the fixing taper hole. Counter bores matched with the rivet nuts are formed in the faces, facing the square pipe, of the connecting piece, and the connecting piece is fixed to the rivet nuts through forward screws penetrating through the counter bores. According to the connecting structure, the strength reduction of a punched carbon fiber thin-walled pipe is compensated through the rivet nuts, and the connecting piece is used for connecting, positioning and fixing, so that the connecting pipe can be accurately and firmly fixed on the side of the square pipe.

Description

technical field [0001] The invention relates to the technical field of positioning brackets, in particular to a high-precision and high-strength carbon fiber thin-wall pipe end face connection structure. Background technique [0002] The machinery manufacturing industry is the cornerstone of modern industry. Nowadays, it has been focusing on improving productivity and processing quality for a long time. With the enhancement of environmental protection awareness and the increasing shortage of natural resources, the limited use of energy and resources in the production process and the reduction of pollution in production play an increasingly important role. Facing the dual challenges of environment and energy, the transformation of the manufacturing industry has also brought new development opportunities for the industry. With the revolutionary breakthrough and cross integration of information technology, new energy, new materials and other important fields and frontier direc...
