Wire cable bending test device

Abstract

The invention discloses a wire cable bending test device comprising a rack. A circular truncated cone is fixed on the rack. A first fixed ejector block and a second fixed ejector block are fixed on the circular truncated cone; a first movable ejector block and a second movable ejector block are arranged on the circular truncated cone; the first movable top block and the second movable top block are provided with driving mechanisms for driving the two to be far away from or close to each other; a wire cable to be tested is sleeved between the first fixed top block and the second fixed top block; one end of the wire cable is fixed on the fixed base, the fixed base is fixed on the circular truncated cone, the other end of the wire cable is fixed on the movable base, the movable base is hingedwith a hinge base fixed on the outer wall of the inner gear ring, the inner gear ring is hinged on the circular truncated cone, a servo motor is fixed on the circular truncated cone, and a driving gear is fixed on the servo motor and meshed with the inner gear ring. The wire cable bending test device can perform multi-point bending test on the wire cable and can adjust the bending part of the wire cable and is convenient to operate and high in stability.

Description

Technical field: [0001] The invention relates to the technical field of cable and wire testing, in particular to a wire and cable bending testing device. Background technique: [0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables include multiple insulated cores, and their respective possible coverings, overall protective layers and outer sheaths. Wires The cable may also have additional uninsulated conductors. Wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables need to have high bending strength to prevent damage to wires or insulators caused by stretching or bending of wires and cables during use. Detects the damage of wires or insulators of wires and cables after bending. However, the current wire and cable bending testing machines have complex structures, high prices, cumber...

AI Technical Summary

Problems solved by technology

Wires and cables need to have high bending strength to prevent wires or insulators from being damaged due to stretching or bending during use. Detect the damage degree of the wire or insulator after the wire and cable are bent, but the current wire and cable bending test machine has a complicated structure, high price, cumbersome operation process, poor test stability, and can only perform bending test on the same part
