Telescopic mechanical arm capable of rotating in omnibearing manner

Abstract

The invention discloses a telescopic mechanical arm capable of rotating in an omnibearing manner. The telescopic mechanical arm comprises a first gear and a second gear which are engaged with each other. The first gear is arranged on a first rotating shaft in a penetrating manner and connected with a first support through the first rotating shaft. The second gear is arranged on a second rotating shaft in a penetrating manner and connected with a second support through the second rotating shaft. Connecting arms are arranged between the first rotating shaft and the second rotating shaft. The first rotating shaft is connected with a first drive device. The first support is connected with a second drive device. The second support is connected with a telescopic external mechanical arm. The external mechanical arm comprises a first mechanical arm body and a second mechanical arm body. One end of the second mechanical arm body is arranged in a hollow cavity of the first mechanical arm body. A gear and rack mechanism is arranged between the first mechanical arm body and the second mechanical arm body. Extension and retraction and omnibearing rotation of the mechanical arm can be achieved, and the telescopic mechanical arm has the beneficial effects of being simple in structure, low in cost, stable in structure and reliable in transmission.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a telescopic mechanical arm capable of omnidirectional rotation. Background technique [0002] Jointed robot, also known as jointed arm robot or jointed mechanical arm, is one of the most common forms of industrial robots in today's industrial field, and is suitable for mechanical automation operations in many industrial fields. For articulated robots, the joint is an important part of it, which realizes the relative movement of the mechanical arm. [0003] At present, most articulated robots have only one kind of relative motion between every two mechanical arms. When the articulated robot needs more complex movements or needs to reach a wider area, it needs to use multiple arms and multiple joints to combine As a result, its structure is complex and bulky. Contents of the invention [0004] Purpose of the invention: the present invention discloses a telescopic mecha...
