Manipulator for transport robot for producing automobiles

Abstract

The invention relates to a robot and in particular to a manipulator for a transport robot for producing automobiles. The manipulator comprises a robot small arm and a plurality of mechanical paws, wherein each mechanical paw is hinged to the small arm through a wrist; each wrist is composed of a rotatable hollow revolving axle; the radial side of each revolving axle is fixedly connected with the corresponding mechanical paw; the other radial side of each revolving axle is hinged to the small arm; each mechanical paw is a hollow mechanical paw; and high-pressure gas which flows through an inner cavity of each revolving axle and an inner cavity of the corresponding mechanical paw drives the corresponding mechanical paw to stretch or shorten. According to the manipulator for the transport robot for producing the automobiles, as the bodies of the mechanical paws are designed into formation with matching outer paws and corresponding inner paws, and in addition, the inner paws can stretch out and draw back, when the robot needs to hold and transport an object with larger size, the inner paws retract into the corresponding outer paws, and thus the thicker outer paws are used to work; and when the robot needs to hold and transport an object with smaller size, the inner paws stretches out of the corresponding outer paws, and thus the thinner inner paws are used to work.

Description

Technical field [0001] The invention relates to a robot in the field of automobile manufacturing, in particular to a mechanical arm of a transport robot. Background technique [0002] Robots have been widely used in industrial production, especially in the handling process of automobile parts production and processing. The robot's arm meets the needs of industrial production through swinging and circular rotation. In the implementation process, after the mechanical claws of the robot arm move toward the object, the object is held and lifted by the movement of the robot arm. In the prior art, the mechanical claw can only bend and swing, and the size of the claw body is fixed; the current robot manipulator uses the same thickness when handling objects of different sizes Mechanical claws or replace robots of different sizes; if mechanical claws of the same thickness are used to handle objects of different sizes, large robots may hold small objects or small robots may hold large obj...

AI Technical Summary

Problems solved by technology

In the prior art, the mechanical claws can only perform actions such as bending and swinging, and the size of the claw body is fixed; at present, the manipulators of the robot use the same thickness when holding and transporting objects of different sizes. Robotic claws or replace robots of different sizes; if using the same thickness of mechanical claws to hold and transport objects of different sizes, there will be situations where a large manipulator holds a small object or a small manipulator holds a large object, which may cause the handling of objects Difficult phenomenon; if you change robots of different sizes to hold and carry items of different sizes, it will waste replacement time, reduce production efficiency, and increase production costs
