Method for generating parameters of electric screen cabinet

Abstract

The invention discloses a method for generating parameters of an electric screen cabinet. The method comprises the following steps of establishing a rectangular framework model according to boundary dimensions of the electric screen cabinet under a Pro / ENGINEER environment, and controlling dimension incidence relation of the electric screen cabinet, wherein the framework model comprises a reference line and a reference surface; performing section beam design by use of a steel structure generating module in Pro / E, and generating a cabinet body framework of the electric screen cabinet according to the framework model; constructing reference lines and reference surfaces for other section beams in the electric screen beams, and establishing constraint relations between the reference lines and reference surfaces and the framework model or the cabinet body framework; adding components including a front door, a top plate and side plates in the cabinet body framework, and finishing assembly of the electric screen cabinet. The method disclosed by the invention can be used for solving the technical problems in the prior art that sectional materials with same sections and different lengths require repeated modeling, the design time is wasted, furthermore after assembly is finished, when a cabinet body is changed, related parts need to be changed one by one, so that the workload is high and the omission possibility is high.

Description

technical field [0001] The invention relates to a modeling method for electrical products, in particular to a rapid modeling and design parameter rapid generation method applied to electrical standard panel cabinets. Background technique [0002] Electrical standard screen cabinets are mostly composed of columns, beams, door panels and other components. When performing three-dimensional modeling, the same type of profiles are often used, so that each time the same cross-section and different length profiles are modeled, a lot of waste will be wasted. energy and time. In addition, the frame of the electrical screen cabinet is mostly a space structure. In order to ensure that the mutual relationship remains unchanged when the model is modified later, it is necessary to establish a complex reference relationship, which is prone to errors. At present, in the regeneration process of the electrical standard panel cabinet assembly model, it is often only the change of the length, ...

Problems solved by technology

[0007] In view of this, the purpose of the present invention is to provide a method for generating electrical screen cabinet parameters, which solves the problem in the prior art that when building an electrical screen cabinet model, multiple modeling is required for profiles with the same cross-section and different lengths, which wastes design time. And after the assembly is completed, when the cabinet body is changed, the parts involved need to be changed one by one, the workload is relatively large, and technical problems that are easy to miss
