The invention discloses a five-degree-of-freedom mechanical arm applicable to a narrow space. The five-degree-of-freedom mechanical arm comprises a shoulder joint, a big arm, a small arm and a wrist joint, thus the mechanical arm has multiple degrees of freedom of big-arm rotation, small-arm rotation, wrist-joint rotation, wrist-joint gyration and wrist-joint retraction and the like, the adjustability of the mechanical arm is greatly improved so that the mechanical arm can be precisely adjusted to any work position in a work space, and the work accuracy of the mechanical arm is improved; meanwhile, the mechanical arm can be better stretched into the narrow work space, the using range of the mechanical arm is enlarged, and the adaptability of the mechanical arm to the narrow work space is improved.
Description
technical field [0001] The invention relates to the technical field of industrial robots, in particular to a five-degree-of-freedom mechanical arm suitable for narrow spaces. Background technique [0002] A manipulator is an automatic operating device that can imitate certain actions of a human hand to grab, carry objects or operate tools according to a fixed program. It is characterized by being able to complete various expected operations through programming; the manipulator is the earliest Industrial robots are also the earliest modern robots. They can replace human heavy labor to realize mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, they are widely used in machinery manufacturing, metallurgy, electronics, light industry and Department of Atomic Energy etc. However, the existing manipulators generally have 6 degrees of freedom, and their shoulder joints are fixed on the ground or moved relative ...
