Manufacturing method of carbon fiber composite material rectangular hollow pipe 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 robot arm and the obtained rectangular hollow tube. Background technique [0002] The function of the robot arm is as the transmission part of the industrial robot. Most of the robot arms that have been used are made of aluminum alloy or steel. Due to the insufficient rigidity of these materials, the fatigue resistance, and the excessive specific gravity, the flexibility is not high, and the thermal expansion coefficient 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 large bearing capacity, good rigidity, and light weight. The movement of the arm is more stable when working, and the movement and stop ar...
