Problems solved by technology

[0002] Parallel mechanisms have the advantages of high stiffness, high precision, and large load-carrying capacity. Researchers have invented a large number of parallel mechanisms, but most of them are three-degree-of-freedom and six-degree-of-freedom parallel mechanisms. There are few invention patents involving two-degree-of-freedom parallel mechanisms
Moreover, the general two-degree-of-freedom parallel mechanism is a two-branch structure, and the load-carrying capacity is weak. Although some two-degree-of-freedom parallel mechanisms have a three-branch structure, the stress distribution on each branch is uneven due to the unreasonable distribution of kinematic pairs. , some branches are subjected to greater stress and greater wear and tear, and the structure of some mechanism kinematic pairs is too complicated, assembly is very difficult, and operation is inconvenient

Abstract

The invention provides a two-freedom-degree parallel mechanism for improving load capacity. The two-freedom-degree parallel mechanism comprises a machine frame, a movable platform, a first supporting foot, a second supporting foot and a third supporting foot, wherein the first supporting foot, the second supporting foot and the third supporting foot are connected between the machine frame and the movable platform. The second supporting foot and the third supporting foot are telescopic, the lower portion of the first supporting foot is rotatably installed on the machine frame through a first spherical hinge, the upper portion of the first supporting foot is rotatably installed on the movable platform through a first rotating shaft, the lower portion of the second supporting foot is rotatably installed on the machine frame through a cross-shaped connecting piece, the upper portion of the second supporting foot is rotatably connected to the movable platform through a second spherical hinge, the lower portion of the third supporting foot is rotatably installed on the machine frame through a fourth rotating shaft, and the upper portion of the third supporting foot is rotatably installed on the movable platform through a fifth rotating shaft. The two-freedom-degree parallel mechanism is high in rigidity and bearing capacity and simple in geometric structure and has good application prospect.

Description

technical field [0001] The invention relates to the technical field of parallel mechanisms, in particular to a two-degree-of-freedom parallel mechanism for lifting load capacity. Background technique [0002] Parallel mechanisms have the advantages of high stiffness, high precision, and large load-carrying capacity. Researchers have invented a large number of parallel mechanisms, but most of them are three-degree-of-freedom and six-degree-of-freedom parallel mechanisms. There are few invention patents involving two-degree-of-freedom parallel mechanisms . Moreover, the general two-degree-of-freedom parallel mechanism is a two-branch structure, and the load-carrying capacity is weak. Although some two-degree-of-freedom parallel mechanisms have a three-branch structure, the stress distribution on each branch is uneven due to the unreasonable distribution of kinematic pairs. , Some branches bear greater stress and greater wear and tear, and the structure of some mechanism kinem...
