Abstract

The invention discloses a detachable type mechanical arm cable-bunching device adopting peripheral slide spherical hinge connection, and belongs to the field of robots. The cable-bunching device comprises a dual-cable hoop mechanism, a spherical hinge connecting mechanism and a cable-bunching clamp mechanism, wherein the dual-cable hoop mechanism comprises metal dual cables, a metal hoop and a hoop connecting bolt; the spherical hinge connecting mechanism comprises a hoop slide connector, a spherical hinge external connecting part, a spherical hinge internal connecting part and a spherical hinge connecting bolt; and the cable-bunching clamp mechanism comprises a ratchet wheel, a pawl and a ratchet wheel connecting bolt. According to the cable-bunching device provided by the invention, thediameter of the dual-cable hoop mechanism is adjustable to meet different mechanical arm diameter needs. The detachable type mechanical arm cable-bunching device is wide in applicability, is simple instructure and is firm; and meanwhile, the spherical hinge connecting mechanism and the cable-bunching clamp mechanism realize relative motion in the peripheral direction of a mechanical arm, and greatly reduces torsional deflection, caused by rotation of the mechanical arm, of cables.

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
