Robot wrist body and preparation method thereof

Abstract

The invention relates to a robot wrist body and a preparation method thereof, and belongs to the technical field of machines. The robot wrist body is made of an aluminum alloy. The aluminum alloy comprises, by mass, 0.5%-1.3% of Si, 0.2%-0.5% of Mn, 0.17%-0.35% of Mg, 0.5%-1.2% of Ni, 0.8%-1.5% of Be, 2.5%-3.5% of glass fibers, 1.5%-3.0% of nanometer Al2O3 and the balance Al. The preparation method of the robot wrist body includes the steps that the glass fibers and the nanometer Al2O3 are each processed through an activation solution and a modification solution and are then dried; and a metalraw material is heated and smelted into an alloy solution, the glass fibers and the nanometer Al2O3 are added, the mixture is then subjected to pouring to form a green body, and thermal treatment isconducted. The prepared robot wrist body is prepared from the aluminum alloy, is small in mass and high in flexibility and has high strength, tenacity and tensile strength.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a robot wrist body and a preparation method thereof. Background technique [0002] In modern industry, with the popularity of assembly line operations, robots are used more and more widely. Industrial robots are a powerful tool to automate the production process and improve labor productivity. Robotic hands are used in most assembly lines. The wrist is a structural component that connects the arm and the hand, and plays a role in supporting the hand. Its main function is to determine the working direction of the hand. Therefore it needs to have a high degree of flexibility. [0003] In order to ensure the service life and safety during use, the traditional load-bearing parts and connectors basically use steel materials. When the conditions of use are met, some secondary load-bearing parts and connectors can use aluminum alloy instead of steel to undertake the connection role. ...

AI Technical Summary

Problems solved by technology

Although the robot wrist body made of steel has a long service life, the weight of the steel is relatively heavy, which makes the robot relatively cumbersome and has certain defects in flexibility.

In some assembly line operations, the robot hand needs to bear heavy workload and high working intensity, and it also has high requirements on the mechanical properties of the wrist body. The mechanical properties of ordinary aluminum alloys are poor, and it is difficult to meet the requirements for use.
