Foldable mechanical arm steel frame

Abstract

The invention discloses a foldable mechanical arm steel frame. The foldable mechanical arm steel frame comprises a fixed steel frame, a first foldable steel frame and a second foldable steel frame. The fixed steel frame comprises a first stand rod, a second stand rod, an oblique support and a middle cross bar. The first foldable steel frame comprises two first top movable rods, a first middle movable rod and two first bottom movable rods. The second foldable steel frame comprises two second top movable rods, a second middle movable rod and two second bottom movable rods. The foldable mechanical arm steel frame is simple in structure and relatively small in weight; the foldable mechanical arm steel frame can be folded and retracted when not used, the space occupation is greatly reduced; thefoldable mechanical arm steel frame can be unfolded when used, the stress area is increased, the stress load is increased, and the situation that a mechanical arm is damaged due to too large stress of a local part is avoided; and the foldable mechanical arm steel frame can adapt to different working environments through multiple kinds of deformation and can be used on various engineering machines.

Description

technical field [0001] The invention belongs to the field of mechanical arms, and in particular relates to a steel frame of 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, rotatin...
