Embodiment 1

[0054] An intelligent design method for a fixture structure, the specific steps are as follows:

[0055] Step 1. Construct the ontology model of a certain beam part on the aircraft by using ontology-based representation method, and establish the fixture component ontology library and instance ontology library;

[0056] (1) Construct the body model of a beam part on the aircraft. like figure 1 As shown in the figure, a beam part on the aircraft needs to mill holes on the surface F6, and its body model includes the three-dimensional solid model of the workpiece, the basic information of the workpiece and the clamping planning requirements of the workpiece. Among them, the basic information of the workpiece includes: the major category of the workpiece is beam; the fine category of workpiece is straight beam; the material of the workpiece is titanium alloy; the size of the workpiece is medium size. The clamping planning requirements of the workpiece are: the positioning method ...

Abstract

The invention relates to an intelligent design method of a clamp structure, and belongs to the field of computer-aided design of clamps. The method comprises the following steps: constructing a workpiece body model, a clamp element body model and a case body model by utilizing a body-based representation method so as to form a clamp element body library and a case body library; and introducing a knowledge component technology to construct an intelligent model which is capable of automatically completing design tasks. On such basis, rule-based and case reasoning-based methods are combined to form a mixed reasoning mode so that intelligent selection of clamp types is realized, and automatic selection of clamp sizes and rapid assembling of clamp elements are realized through the development of a software platform. The intelligent design method of the clamp structure has the advantages of improving the quality and efficiency of clamp structure design, and reducing the requirements, for the aspects of experience and the like, of the designers.

Description

technical field [0001] The invention relates to an intelligent design method for a fixture structure, which belongs to the field of computer-aided fixture design. Background technique [0002] As a mechanism used to fix, support and clamp workpieces in the process of machining, so that the workpieces are in the correct position relative to the machine tool, fixtures have an important impact on the production quality, efficiency and cost of products. In the design process, due to the complexity of the processed parts, the diversity and uncertainty of the influencing factors, and largely relying on the experience and knowledge of the designer, the design of the fixture is very cumbersome and time-consuming, and it is difficult to understand the field Knowledge is scientifically and effectively inherited and reused. Therefore, for fixture design, traditional design patterns and methods can no longer meet the needs of modern enterprises, and an intelligent design method is espe...
