Light mechanical arm made from carbon fiber composite material

Abstract

The invention relates to the technical field of mechanical arms, in particular to a light mechanical arm made from a carbon fiber composite material. The light mechanical arm made from the carbon fiber composite material comprises a mechanical arm base, a mechanical joint I, a mechanical joint II, a connecting rod I, a mechanism joint III, a connecting rod II, a mechanical joint IV and a tail endexecuting end device which are successively connected, wherein the connecting rods I and II are made from a carbon fiber material; outer wrapping layers of the mechanical joints III and IV are also made from the carbon fiber material; one end of the connecting rod I is connected to the mechanical joint II through a cementing agent by way of cementing while the other end of the connecting rod I isconnected to the mechanical joint III by way of co-curing; and one end of the connecting rod II is connected to the mechanical joint III through the cementing agent by means of cementing while the other end of the connecting rod II is connected to the mechanical joint IV by way of co-curing. By means of the structural arrangement, part of members of the mechanical arm is coated with carbon fibersto form a mixed structure, so that the mechanical arm has higher strength and meanwhile the weight is alleviated under the circumstance of not increasing the dimension of the mechanical arm.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a light mechanical arm made of carbon fiber composite material. Background technique [0002] As a new type of mechanical material, carbon fiber is now more and more mature in its related processes and usage methods, and it is used more and more widely. Carbon fiber has high specific strength, high specific modulus, high temperature resistance, corrosion resistance, Fatigue resistance and other advantages, compared with the traditional mechanical arm, the carbon fiber mechanical arm is lighter, and the human-computer interaction is safer, and it will not increase the weight and size of the mechanical arm. The traditional connection methods of the mechanical arm, such as screws, bolts, etc., destroy the structure of the connecting part, resulting in a decrease in its strength, and these connection methods make the connection not compact enough.
