Abstract

A multistage rotary and telescopic mechanical arm comprises a first gear and a second gear which are engaged with each other. The first gear is connected with a first support through a first rotating shaft. The second gear is connected with a second support through a 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, a second mechanical arm body and a third mechanical arm body. One end of the second mechanical arm body is arranged in a hollow cavity of the first mechanical arm body. One end of the third mechanical arm body is arranged in a hollow cavity of the second mechanical arm body. The first mechanical arm body and the second mechanical arm body are in threaded connection, and the second mechanical arm body and the third mechanical arm body are in threaded connection. The second mechanical arm body and the third mechanical arm body are each driven by an independent drive system. Multistage extension and retraction and omnibearing rotation of the mechanical arm can be achieved, and the multistage rotary and telescopic mechanical arm has the beneficial effects of being simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a multi-stage rotating telescopic mechanical arm. 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 multi-stage rotating telescopic...
