Method for manufacturing rectangular hollow tube of carbon fiber composite material for mechanical arm

Abstract

The invention provides a manufacturing method of a carbon fiber composite material rectangular hollow pipe for a mechanical arm, and the obtained rectangular hollow pipe. A carbon fiber composite material serves as a raw material and is carbon fiber prepreg; the prepreg comprises one-way and fabric prepregs and the rectangular hollow pipe is manufactured by a mould pressing inflation forming method. According to the manufacturing method of the carbon fiber composite material rectangular hollow pipe, a rectangular thin-walled hollow pipe is manufactured by performing mould pressing inflation combined forming on the carbon fiber prepreg serving as the raw material. Compared with the prior art, the invention has the advantages that the carbon fiber composite material rectangular hollow pipe has high bearing capacity, high rigidity and light weight; during operation, the arm is more stable in action and moves and stops more quickly; the arm can be quickly positioned by the vibration damping characteristic of the carbon fiber composite material; the carbon fiber composite material is applicable to precision equipment due to the zero thermal expansion coefficient; equipment investment is small; a mould is simple to manufacture; production energy consumption is low; production period is short; automatic production is realized.

Description

technical field [0001] The invention relates to a method for manufacturing a rectangular hollow tube of carbon fiber composite material for a mechanical arm and the obtained rectangular hollow tube. Background technique [0002] The role of the robot arm is as a transmission part of an industrial robot. Most of the existing robot arms are made of aluminum alloy or steel. Due to the lack of rigidity, fatigue resistance, and excessive specific gravity of these materials, the flexibility is not high and the coefficient of thermal expansion is large. . [0003] Carbon fiber composite materials have excellent mechanical and chemical properties, such as high specific strength, large specific modulus, good fatigue resistance, and good chemical corrosion resistance. The arm made of carbon fiber composite material has a large load-bearing capacity, good rigidity, and light weight. When working, the arm moves more smoothly and moves and stops more quickly. The inherent vibration dam...
