Foldable mechanical arm

Abstract

The invention discloses a foldable mechanical arm. The mechanical arm comprises a first mechanical arm steel frame, a second mechanical arm steel frame and a stress control body which are sequentiallyconnected through a second steering engine and a third steering engine. The first mechanical arm steel frame and the acting point of the mechanical arm are connected through a first steering engine.A first compression cylinder is arranged between the first steering engine and the first mechanical arm steel frame. A second compression cylinder is arranged between the second steering engine and the second mechanical arm steel frame. A third compression cylinder is arranged between the third steering engine and the stress control body. The mechanical arm provided by the invention is simple in structure and low in overall weight, and can be folded to retract or extend to be unfolded according to the specific use conditions, the occupied space is reduced, the stress area and stress loads arealso ensured, the adaptability of the mechanical arm is improved, and more working requirements are met by simulating the work of an upper limb or a lower limb according to the specific conditions.

Description

technical field [0001] The invention belongs to the field of mechanical arms, and in particular relates to a foldable mechanical arm. Background technique [0002] The robotic arm is a high-precision, high-speed dispensing robotic arm. The robotic arm is a multi-input multi-output, highly nonlinear, and strongly coupled complex system. Because of its unique operational flexibility, it is widely used in industrial manufacturing, medical treatment, entertainment services, military and other fields have been widely applied. [0003] Today's robotic arms generally realize the normal functional operation of the robotic arm by stretching, rotating, and lifting. In order to meet the telescopic, rotating, and lifting functions of the robotic arm, many of today's robotic arms are complex in structure and bulky, which not only increases the size of the robotic arm. The space occupied also increases the stress on the functional parts or joints when stretching, rotating or lifting. Aft...

[0003] Today's robotic arms generally realize the normal functional operation of the robotic arm by stretching, rotating, and lifting. In order to meet the telescopic, rotating, and lifting functions of the robotic arm, many of today's robotic arms are complex in structure and bulky, which not only increases the size of the robotic arm. The space occupied also increases the stress on the functional parts or joints when stretching, rotating or lifting. After long-term use, the strength of the robotic arm will be reduced, affecting the normal operation of its functions, and in severe cases, it will cause damage to the robotic arm. even pose a safety hazard
