A Circumferential Sliding Ball Hinge Connection Detachable Robotic Arm Harness Device

Abstract

The invention discloses a circumferential sliding ball hinge connected detachable wire harness device of a mechanical arm, which belongs to the field of robots. The wire harness device specifically includes a double wire hoop mechanism, a ball hinge connection mechanism and a wire harness clamp mechanism. The double wire hoop mechanism includes metal double wires, metal hoops and hoop connection bolts; the ball hinge connection mechanism includes The hoop sliding connecting piece, the ball hinge external piece, the ball hinge internal piece and the ball hinge connecting bolt; the harness clamp mechanism includes a ratchet, a ratchet and a ratchet connecting bolt. The diameter of the double-wire hoop mechanism in the wire harness device provided by the present invention is adjustable to meet the needs of different diameters of mechanical arms. It has wide applicability, simple structure, and firmness; The relative movement of the arm in the circumferential direction greatly reduces the torsional deformation of the cable caused by the rotation of the mechanical arm.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a circumferential sliding ball hinge connection detachable wire harness device for a mechanical arm. Background technique [0002] When the robotic arm is used in practice, tooling is generally installed at its end, such as electric (pneumatic) grippers, sensors, etc., and correspondingly applied to power cables, control cables, etc. The requirements and types of these cables will vary according to different working conditions. Generally, all routing space is not reserved for them inside the manipulator. It is inevitable that some cables will be fixed outside the manipulator and cause inconvenience. matter of convenience. [0003] At this stage, there are relatively few schemes for external wiring of the robotic arm. The simplest method is to paste the wire clip directly on the robot arm, which can achieve the effect of short-term wire harness, but first, it will affect the ap...

Problems solved by technology

The simplest method is to paste the wire clip directly on the robot arm, which can achieve the effect of short-term wire harness, but first, it will affect the appearance of the robot arm, and second, it will easily cause damage when the robot arm rotates at a large angle. The cable clamps fall off; some are bound to the robotic arm with non-slip cloth straps, but the structure is not strong enough. The torsion generated by the high-speed operation of the robotic arm will deform it, and cause damage to the straps and cables after a long time; Some use metal hoops to fix the cables on the manipulator, but the cable clamps cannot rotate relative to the hoops. In the case of a relatively large rotation range of the manipulator, the cables will be twisted and eventually damaged. or disconnected communication

Although the existing external wiring scheme of the manipulator can play the role of wire harness in a short time, there are shortcomings such as loose wire harness, lack of relative movement between the cable and the clamp, and the inability to adjust the diameter of the clamp. Some damage to the cable
