According to the mechanical arm and the position adjusting method thereof, the problem that the degree of freedom of an existing mechanical arm is not enough to limit the application scene of the existing mechanical arm is solved, position adjustment can be achieved at four displacement degrees of freedom, and the technical effects of being high in precision, good in rigidity and multiple in mechanical arm application scene are achieved.

Description

technical field [0001] The invention relates to the technical field of industrial production, in particular to a mechanical arm and a position adjustment method thereof. Background technique [0002] In recent years, in the production lines of machinery manufacturing, metallurgy, electronics and other industrial fields, multi-joint manipulators have developed rapidly and are widely used in other fields. The degree of intelligent automation of manipulators is also getting higher and higher. Its production application technology More and more mature, the mechanical arm can replace the heavy labor of human beings to realize the mechanization and automation of production. [0003] At the same time, in some industrial fields and scientific research laboratories, there are some simple and repetitive operations, which also have high requirements for intelligent automation, but because the operations are simple, they do not require multiple degrees of freedom. At the same time, the...
