Multiple-degree-of-freedom industrial robot manipulator

Abstract

The invention relates to a multiple-degree-of-freedom industrial robot manipulator. A lower end of a first rod of the manipulator is connected to a working platform, while an upper end of the first rod is connected with one end of a second rod; the other end of the second rod is connected to an actuator; a lower end of a first expansion link is connected to a slider that is mounted in a sliding groove; an upper end of the first expansion rod is connected to a first sliding sleeve; the first sliding sleeve sleeves the first rod; a lower end of a second expansion link is connected to the working platform, while an upper end of the second expansion link is connected to a third sliding sleeve; the third sliding sleeve sleeves the second rod; one end of a third rod is connected to a second sliding sleeve that sleeves the second expansion link, while the other end of the third rod is connected to the actuator; the working platform is mounted on a trolley. The multiple-degree-of-freedom industrial robot manipulator has the advantages of large working space, large digging force, good stress and the like of a traditional hydraulic machine mechanism, and furthermore, the number of active rods and controllable motors is further reduced, and the complexity of a frame transmission system is reduced.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a multi-degree-of-freedom industrial robot manipulator. Background technique [0002] Since the 1960s, robotic arms have been widely used in the processing and logistics industry, which not only reduces the work intensity of people, but also greatly improves the processing and production efficiency. However, most of these mechanical arms are fixed on the base. With the development of industry and technology, the working space of this mechanical arm installed on the fixed base is extremely limited, which cannot meet the needs of actual tasks. In response to this situation, since the late 1980s, many research institutions at home and abroad have carried out research on mobile manipulators. The mobile manipulator is mainly composed of a walking device, a manipulator and a grabbing device. On the basis of inheriting the advantages of the traditional manipulator, the working space of the man...
