Robot 3D drag chain

Abstract

The invention discloses a robot three-dimensional drag chain. The robot three-dimensional drag chain is formed by connecting multiple sections of single chain links. Each single chain link is annular as a whole and is separated into a left chain link and a right chain link by a plane passing the midperpendicular of the single chain link, and the two ends of the left chain link and the right chain link are overlapped with each other at the partition part. One group of groove and hasp which are buckled with each other are arranged in the center of each single chain link, a left spherical surface connector is arranged in the middle of the groove, a right connecting ball is arranged in the middle of the lower part of the hasp, and the right connecting ball can be connected with the spherical surface of the left spherical surface connector in the single chain link below the right connecting ball. The right chain link comprises an inner cambered surface and an outer cambered surface, and the outer cambered surface at the upper part of the right chain link adopts a gradual change structure of which the two sides are thicker than the middle. The robot three-dimensional drag chain overcomes the problem that the traditional robot drag chain is difficult to bend due to the even design of outer ring surfaces in the single chain link structure and is therefore not portable enough when a cable is mounted in the drag chain and the cable in the drag chain is repaired and solves the problem that dust in the air, and oil stains, water stains and the like, produced during robot operation, enter the inner part of the drag chain and pollute the cable due to poor air tightness.

Description

technical field [0001] The invention relates to a drag chain structure, in particular to a robot three-dimensional drag chain. Background technique [0002] Due to the uniform design of the outer ring surface in the single chain link structure of the existing robot towline, it is not easy to bend. When installing cables in the towline, it is not easy to install the cables in it easily, resulting in increased labor costs and installation difficulties. It is inconvenient to check and repair the internal cables of the towline. In addition, the robot drag chain has not given too much consideration to the issue of sealing. Often due to the poor sealing of the drag chain, the problem that the internal cables are polluted by the outside world occurs. Contents of the invention [0003] The object of the present invention is to provide a robot three-dimensional drag chain that solves the above problems, can easily install cables in it, can be bent freely, and has good sealing per...
