Abstract

The invention relates to a mechanical arm, and belongs to hoisting carrying machines. A lifting supporting plate is assembled on a base through a lifting unit, a mechanical arm base is fixedly installed on the lifting supporting plate, and a folding or unfolding three-section arm is installed on the mechanical arm base through a rotary disc assembly, an installation head and a stretchable unit which are sequentially connected in series; the rotary disc assembly is formed by a rotating shaft, a rotary wheel, a rotary disc base, a driving belt, a first connecting piece, a second connecting piece and a shape memory polymer driver in an assembled manner; and the lifting unit and the stretchable unit are each formed by shape memory polymer and a shape memory alloy net. According to the mechanical arm, the shape memory characteristic of a shape memory material is creatively used, a traditional mechanical driving mode is replaced with a shape memory effect driving manner, and the mechanical arm has the beneficial effects of being simple in structure, high in positioning accuracy, small in structure weight and flexible and reliable in operation, and reducing the complexity of the operation process.

Description

technical field [0001] The invention belongs to hoisting and transporting mechanical equipment, and mainly relates to a mechanical arm. Background technique [0002] The hoisting and handling machinery can partially or completely replace the operator for production, reduce the labor intensity of the operator, and achieve safe and efficient production. The robotic arm is an important part of the handling machinery, extending the operating range of the manipulator. However, at present, most of the manipulators use the traditional mechanical drive method, which has a cumbersome structure, large mass, complicated control process, and low positioning accuracy, which limits the scope of application of the manipulator to a certain extent. Contents of the invention [0003] The purpose of the present invention is to address the shortcomings of the above-mentioned prior art, and to design and provide a mechanical arm with a new structure, so as to simplify the structure, reduce th...
