Abstract

A multistage telescopic composite 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 and are driven by independent drive systems. By means of the design, multistage stretching and retracting can be achieved through threaded connection between the mechanical arm bodies, and the advantages of being simple and stable in structure, low in cost and wide in telescopic range are achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a multi-stage retractable composite 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. [0003] At present, in most joint robots, the expansion and contraction between every two mechanical arms is realized by the lead screw device, but for the expansion and contraction between multi-stage mechanical arms, the lead screw device does not have enough space to set up. Contents of the invention [0004] Purpose of the invention: The present invention discloses a multi-stage telescopic compound mechanical arm, which has a simple and compact structure and low cost, and can realize multi-stage telescopic expansion of the mechanical arm. [0005] Tech...
