An operating arm of a tubular piece handling manipulator

Abstract

The invention discloses an operation arm for a pipe type piece carrying mechanical hand. The operation arm comprises a hollow rod body stretching into a pipe cavity of a pipe type piece, an air bag sleeve arranged on the hollow rod body in a sleeving manner, an adjusting rod, an air supply pipe, an air suction pipe, at least one pair of telescopic arms connected with the adjusting rod, and suction cups installed on the telescopic arms, wherein the adjusting rod, the air supply pipe and the air suction pipe are arranged in the hollow pipe body. The top end of the adjusting rod extends out of the hollow rod body and is used for adjustment. The air supply pipe is connected with the air bag sleeve through air supply holes formed in the hollow rod body and is used for inflation for air supply of the air bag sleeve so that a pipe opening of the pipe type piece can be filled with the inflated air bag sleeve. The air suction pipe is connected with the suction cups and used for providing suction force for the suction cups. Corresponding guiding grooves used for expansion of the telescopic arms are formed in the axial rod wall of the hollow rod body. The telescopic arms can expand to penetrate the guide grooves to extend to the pipe cavity of the pipe type piece under the effect of the adjusting rod, and the suction cups can make contact with the pipe wall of the pipe type piece so as to suck the pipe wall of the pipe type piece. By the adoption of an air bag sleeve expansion manner and a suction cup suction manner, the piece can be flexibly taken.

Description

technical field [0001] The invention relates to an operating arm, in particular to an operating arm of a manipulator for transporting tubular parts, and belongs to the technical field of manipulators. Background technique [0002] At present, with the development of mechanical tools and the needs of production, manipulators are applied to certain machines or equipment to replace manual work such as picking or placing objects, which can make the entire production line more regular, stable, and continuous. In order to ensure a constant production and working state, whether it is a single-joint manipulator or a multi-joint manipulator, they all have their own specific application places. [0003] For the production line of pipe-shaped parts (such as hollow pipes), the use of manipulators to handle pipe-shaped parts can greatly improve production efficiency. However, the existing handling manipulators basically act on the outer surface of the handling object by clamping, so the...

Problems solved by technology

However, the existing handling manipulators basically act on the outer surface of the handling object by clamping, so the operating end of the handling manipulator that is in direct contact with the handling object has a large size and takes up a lot of space; and when handling products of different sizes, Different sizes of handling operation ends are required, so there are problems such as poor versatility
