Multi-degree-of-freedom mechanical arm

Abstract

The invention discloses a multi-degree-of-freedom mechanical arm. The multi-degree-of-freedom mechanical arm comprises a bracket, a first rod body, two telescopic rods, a connecting mechanism and a plurality of claw bodies, wherein a substrate which can slide horizontally is arranged on the lower portion of a second right-angled edge which is horizontally arranged, and an annular groove is formed in the lower surface of the substrate; the first rod body is horizontally arranged below the substrate and a first sleeve externally sleeves the first rod body; the upper ends of the two telescopic rods are fixedly arranged on the outer wall of the first sleeve, separately, and one of the telescopic rods is driven by a hydraulic oil cylinder to stretch; the connecting mechanism comprises a first round disc, a second sleeve, a hollow cylinder, a compression spring, a second round disc and two second rod bodies; and the plurality of claw bodies are movably arranged on the lower surface of the second round disc, and one of the claw bodies is elastically hinged to the lower surface of the second round disc through a locking spring. The plurality of claw bodies rotate in multiple directions, multiple planes and multiple angles by means of an operation of increasing the inclination angles between the two telescopic rods and the vertical direction by adjusting the lengths of the two telescopic rods and combining rotation of the first sleeve, so that the multi-degree-of-freedom mechanical arm can be suitable for a construction operation in a complicated environment.

Description

technical field [0001] The invention relates to the field of mechanical technology. More specifically, the present invention relates to a multi-degree-of-freedom robotic arm. Background technique [0002] In many industrial production operations, the operating environment is harsh and the operation content is complex, and the production operations cannot be completed by manpower alone. In order to improve the degree of mechanized operations and reduce the intensity of manual labor and operation risks, mechanical arms are introduced in industrial production to replace manual operations; The robotic arm can automatically grab and carry the workpiece according to the fixed program, which has the advantages of convenient use and labor saving. [0003] However, the existing mechanical arms have the disadvantages of complex structure, limited rotatable freedom, inflexible operation, and inaccurate positioning; It will cause industrial accidents, and the low handling efficiency r...
