基于SolidWorks的组合夹具CAD系统的开发 总被引:4,自引:1,他引:4
文章针对西安昆仑机械厂提出的数控机床用的组合夹具,常因生产时间交替,造成对同一零件,其组合夹具结构和安装方位差异较大,从而使编好的数控加工程序不能直接重复使用的问题,以SolidWorks为平台,建立了组合夹具CAD系统.该系统运用SolidWorks面向对象的参数化特征造型方法和成组技术原理,建立组合夹具元件库和对组合夹具进行分类、装配、管理.该系统的建立对组合夹具的推广,CAD/CAM的集成,有一定促进作用.同时,作者借助VC 6.0和SolidWorks的API函数对SolidWorks的二次开发进行了有益的探索. 相似文献

Fixture design is an important procedure in many manufacturing operations in terms of maintaining product quality, consistency and assisting the assembly, machining and inspection processes. A robust fixture design approach is presented in this study. It treats fixture layout as a multi-objective optimization problem, which considers both the mean and the variation of the mean localization errors of the machining features in a set-up, and the distance of the location points among the locators to ensure the location is stable and reliable. The non-dominated ACO and GA are proposed to solve this multi-objective problem, and their performances are compared. 相似文献

Fixture layout including locator layout and clamp layout plays a vital role in fixture performance. Current researches have been focused on fixtures for components with regular geometry, the results of which are not always applicable for components with complex geometry. This paper presents a methodology of fixture layout optimisation carried out in consideration of the repeatability, immobility and stability of fixturing. The locator layout is optimised based on the criteria of workpiece repeatability and location accuracy. The clamp layout optimisation offers a method to minimize the magnitude of the clamping force. The procedure of clamp optimisation is (1) to find the feasible clamping position in terms of the immobility requirement; (2) to get the best clamp among the feasible clamping positions under constraint of the stability. The optimal fixture layout is considered in a global range and is especially suitable for the workpiece with complex surfaces. A fixture layout design for the aerofoil of a turbine blade is analysed as an example, and the optimal fixture layout is demonstrated. 相似文献

The design of machining fixtures is a highly complex process that relies on designer experience and his/her implicit knowledge to achieve a good design. In order to facilitate its automation by the development of a knowledge-based application, the explicit definition of the fixture design process and the knowledge involved is a prior and a fundamental task to undertake. Additionally, a fundamental and well-known engineering principle should be considered: the functional requirements and their associated constraints should be the first input to any design process. Considering these two main ideas, this paper presents the development undertaken to facilitate the automation of the fixture design process based on a functional approach.In this context, the MOKA methodology has been used to elicit fixtures knowledge. IDEF0 and UML have been used to represent the fixture design process. A methodology based on the function concept and aiming to formalize such design process is proposed. Fixture functional requirements have been defined and formalized. Functional fixtures elements have been used to create a functional design solution, the link of these elements with the functional requirements and with typical commercial fixture components has been defined via tables and rules mapping. And finally, a prototype knowledge-based application has been developed in order to make an initial validation of the proposed methodology. 相似文献
