Cable restraining device suitable for robot executer

Abstract

The invention provides a cable restraining device suitable for a robot executer. The cable restraining device comprises an upper half ring, a lower half ring and a cable fixing base. The upper half ring and the lower half ring are the same in radius and are spliced to form an integral circular ring, and the two ends of the lower half ring and the two ends of the upper half ring are fixedly connected. The cable fixing base is of an arc structure, and a plurality of axially-formed arc fixing base grooves are formed in the inner wall of the cable fixing base. A plurality of upper half ring grooves corresponding to the fixing base grooves are formed in the outer wall of the upper half ring. The fixing base grooves and the upper half ring grooves are spliced into cable holes used for fixing a cable. The cable fixing base is fixedly connected with the upper half ring. According to the cable restraining device, the cable is kept close to a robot with the short distance, and meanwhile the problems such as interference caused by cable postures in the using process are solved.

Description

technical field [0001] The invention belongs to the field of wiring technology, and in particular relates to a cable restraint device suitable for robot actuators. Background technique [0002] At present, except for the spraying robot, most industrial robots use the method of installing cables from the outside. Especially when installing the end effector that needs to be connected to the cable, the cable needs to be fixed on the robot arm. In general, a cable bracket is installed on the arm of the robot to fix the bellows, and the bellows are used to cover the cables, but this method requires a long cable between the fixed seat and the actuator to make the end perform When the end effector performs a relatively large rotation, and the position of the cable is uncontrollable, when the rotation angle of the end effector is small or in a non-rotating state, the cable cannot be wound on the forearm, but hangs on the forearm at random with the robot posture On the forearm, ther...

Problems solved by technology

In general, a cable bracket is installed on the arm of the robot to fix the bellows, and the bellows are used to cover the cables, but this method requires a long cable between the fixed seat and the actuator to make the end perform When the end effector performs a relatively large rotation, and the position of the cable is uncontrollable, when the rotation angle of the end effector is small or in a non-rotating state, the cable cannot be wound on the forearm, but hangs on the forearm at random with the robot posture On the forearm, there is a lot of sagging. If the cable material is hard, it will protrude outward in an indeterminate direction and posture, which may easily cause interference during movement and touch the surface of the workpiece.
