Manipulator arm for handling tubes

Abstract

The invention discloses a mechanical hand operation arm for carrying a pipe type part. The mechanical hand operation arm comprises a hollow rod used for stretching into a pipe cavity of the pipe type part, an adjusting rod, air suction pipes, at least one pair of telescopic arms connected with the adjusting rod, and suckers installed on the telescopic arms, wherein the adjusting rod and the air suction pipes are arranged in the hollow rod. The top end of the adjusting rod stretches out of the hollow rod for adjustment. The air suction pipes are connected with the suckers and used for providing suction force for the suckers. Corresponding guide grooves for the telescopic arms to expand out are formed in the axial rod wall of the hollow rod, and the telescopic arms can expand and penetrate through the guide grooves under the action of the adjusting rod to stretch into the pipe cavity of the pipe type part and make the suckers in contact with the pipe wall of the pipe type part to suck the pipe wall of the pipe type part. The mechanical hand operation arm has the advantages that the operation arm is small in initial state dimension and occupied space due to the mode of carrying out suction of the suckers through insertion from the cavity of the product, and the dimension of the operation end can be flexibly changed through the adjusting control of the adjusting rod in use so that the operation arm can be suitable for products with pipe cavities in different dimensions.

Description

technical field [0001] The invention relates to an operating arm, in particular to a manipulator operating arm used for handling 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 oper...

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
