Multi-joint flexible mechanical arm

Abstract

The invention provides a multi-joint flexible mechanical arm. The multi-joint flexible mechanical arm comprises a driving part, rotating joints, pull wires, brakes and a comprehensive brake, wherein the driving part drives multiple push rods to perform a linear reciprocating motion; the rotating joints include longitudinal rotating joints and transverse rotating joints orthogonally staggered and connected; pivot shafts of the longitudinal rotating joints are perpendicular to pivot shafts of the transverse rotating joints; the longitudinal rotating joints and the transverse rotating joints can rotate and stop around respective pivot shafts; multiple pull wires penetrate through each rotating joint in sequence from the peripheries of the rotating joints; each pull wire is singly connected with the corresponding push rod; the other ends of the pull wires penetrate out of the rotating joint at the most front end for fixing; all the rotating joints are provided with the brakes; and the comprehensive brake uses the linear reciprocating motion of the push rods to tighten or release the pull wires so as to control rotation of the rotating joints. The multi-joint flexible mechanical arm cancels a joint motor, reduces the joint structure complexity and the electric energy consumption, and is provided with a push rod extension detecting device for replacing all joint detecting devices of the arm to reduce the cost.

Description

Technical field [0001] The invention relates to the field of robots, in particular to a multi-joint flexible mechanical arm. Background technique [0002] The robotic arm is one of the most commonly used robots in the industry. As the industrial level and requirements continue to increase, the requirements for robotic arm robots are also increasing. Robots with more degrees of freedom are flexible, thereby increasing the scope of application and working space, and remote processing Ability, able to enter the narrow curved space for flaw detection, and have the ability to avoid obstacles, which is not easily achieved by conventional robots. In addition, there is no need to disassemble and assemble the box, and enter its interior through the peephole to check the operation of the machine or the cleaning and maintenance of key parts. The curved pipeline connection is sealed, inspected, and minimally invasive technology. The serpentine multi-joint flexible arm is usually installed o...
