Wiring harness stretch performance detection device

Abstract

The invention discloses a wiring harness stretch performance detection device which comprises a working platform, a pull load mechanism and a clamping mechanism. The pull load mechanism comprises a cylinder. An output part is a piston rod of the cylinder. The clamping mechanism comprises two groups of clamping components. Each clamping component comprises two fixing plates. Arc grooves used for clamping wiring harness are arranged in the corresponding positions of the two fixing plates. One of the clamping components is fixedly arranged on the working platform. The other clamping component is connected with the output part of the pull load mechanism in a rigid mode and capable of moving under the action of the pull load mechanism. Due to the fact that load and release motion of the wiring harness to be detected are executed by a pneumatic system, the wiring harness stretch performance detection device is capable of being simple and direct, lower in cost, environment-friendly and free from pollution. Load speed is adjusted by a speed adjustment valve so that detection is more accurate, comprehensive, real and reliable. The clamping mechanism of the wiring harness stretch performance detection device is simple and direct in design and convenient to install and operate. Detail processing of the surface is unique. The surface of the wiring harness to be detected is not pressed and damaged due to the design of double-arc transition. The wiring harness is capable of being normally used after the wiring harness is detected so that waste is avoided.

Description

technical field [0001] The invention relates to a wire harness extension performance testing device. Background technique [0002] The automotive wiring harness is the main network of the automotive circuit, and there is no automotive circuit without the wiring harness. The sensor harness is one of the important parts of the car, which is used to conduct various signals required by the car control system. The sensor wiring harness is generally composed of two copper wires with a diameter of 0.5mm and a rubber protective cover with an outer diameter of 6-8mm through the injection molding process, and the total length is generally about one meter. During the assembly and maintenance of the vehicle, it is inevitable that the wire harness will bear a certain degree of tension in the axial direction, which will cause axial tensile deformation of the wire harness, and this stretching deformation is required not to affect the wire harness. normal work. Therefore, in the process ...

Problems solved by technology

Traditional test equipment is often very complicated, using electric cylinders or hydraulic cylinders as drivers, the equipment is expensive, bulky, and inconvenient to operate; and due to the incomplete design of the clamping and fixing device of the wire harness, permanent pressure will be left on the surface of the wire harness during the test. traces, the tested sample can only be scrapped after the test
