A Method for Generating Full-scale Wiring Harness Tooling Board Drawing Based on CAD Platform

Abstract

The invention discloses a method for generating full-size harness tool board pictures on the basis of CAD (computer aided design) platforms. The method includes editing various command modules in ARX (auto-regressive with extra inputs) development environments of C++ language supported by the CAD platforms and combining the command modules and original commands of the CAD platforms to carry out operation. The method has the advantages that various parameters are respectively set by the aid of CAD attribute blocks of tree structures, and accordingly requirements on data extraction and positioning at follow-up steps can be met; nodes and paths are used as basic units, abstraction and simulation are carried out, connecting rod system models of plane kinematics are built, accordingly, the continuous consistency of topological relations among various rod pieces of tool boards can be guaranteed in various placing procedures, operation on the paths on the CAD platforms is transformed into movement change in the connecting rod system models, constant connection states of the nodes and the paths can be guaranteed, and integral movement and operation can be carried out by the nodes and the paths; boundary block diagrams of the hardness tool boards are used as boundaries, and connecting rods can be dragged, so that the paths which exceed ranges can be arranged in limited ranges on the basis of the built models.

Description

technical field [0001] The invention relates to the drawing of a full-size wire harness tooling board drawing, in particular to a method for generating a full-size wire harness tooling board based on a CAD platform. Background technique [0002] The wire harness refers to the contact terminal (connector) punched from copper and the wire and cable after crimping, and then plastic insulator or metal shell on the outside, and then bundled with wire harness to form a connected circuit component. [0003] Before the wire harness is made, the wire harness diagram must be drawn on the CAD (Computer Aided Design) platform. The wire harness diagram must take into account the size and shape of each electrical component and the distance between them, and also reflect the relationship between the electrical components. The connection relationship, and at the same time, identify and specify the wrapping of the wire harness. However, the displayed length and the actual length of the wire...

Problems solved by technology

[0004] In the prior art, according to the wire harness diagram, the paths of the wires are sequentially drawn with equal dimensions manually, which is inefficient, heavy workload, and error-prone. Most of the work is redrawn, and the parameters of the cladding material, clips and sheaths also need to be drawn one by one, especially as the wiring harness diagram includes more harnesses, the efficiency and accuracy will be greatly reduced
