Multi-degree-of-freedom mechanical arm

Abstract

The invention relates to a multi-degree-of-freedom mechanical arm. The multi-degree-of-freedom mechanical arm comprises a supporting base, a rotary mechanism, a telescopic mechanism, a pitching drive part, a folding mechanism, a rotary mechanism, an opening-closing mechanism and a mechanical claw, wherein the rotary mechanism is arranged on the bottom of the supporting base; one end of the telescopic mechanism is hinged with the supporting base; one end of the pitching drive part is hinged to the top of the supporting base, and the other end of the pitching drive part is hinged with the telescopic mechanism; the folding mechanism is arranged at the other end of the telescopic mechanism; the telescopic mechanism drives the folding mechanism to linearly move; the rotary mechanism is connected with the folding mechanism; the opening-closing mechanism is arranged at the output end of the rotary mechanism; the mechanical claw is connected with the opening-closing mechanism; and the opening-closing mechanism drives the mechanical claw to open or close. The multi-degree-of-freedom mechanical arm can perform six-degree-of-freedom compound motion, and can be suitable for construction operation of a complex environment.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a multi-degree-of-freedom mechanical arm. Background technique [0002] In many working environments, the content of the work is relatively complicated, such as construction work in the roadway, etc. In order to improve the degree of mechanized work, reduce the intensity of manual labor and work risks, it is necessary to introduce robotic arms to replace manual work. The mechanical arm of engineering operation equipment is mostly a lifting arm. The base of the lifting arm has a slewing device, and the hydraulic motor provides the slewing power. The lifting arm can also complete the pitching and telescopic movement through the pitching cylinder and the telescopic cylinder, and then complete the lifting operation. The control of the above movements is uniform. Realized by hydraulic valve group. [0003] The engineering operation arm in the prior art has limited freedom of ...
