摘要
随着机床加工精度改进,使减少的定位误差,加工精度,制造精密的设备需要相应增加。以满足不同的部门和经济,不同型号和不同程度的精确度的标准进行选择的文件夹的需要。通用夹具直接影响到经济,模块化,组合夹具系统单独夹具可重构性,可重构性和可扩展性的能力和范围之广,通用性强,效率高的方案,强大的功能性元素,使得夹具通用性好,简洁的要素,支持低成本,促进了利用经济价值。
设计是实际生产的组合,通用夹具不能满足生产要求,特别是研磨夹具的设计中,夹具包括定位控制夹紧装置中,刀程序,夹子和定位键的设计和精度分析等方面。
该装置具有良好的精度,特别是用于钻孔,扩22槽的底部钻具零件加工程序。该夹具具有夹紧力剂,具有现代机床夹具的高效和精密的特点要求,能有效地降低时间原辅工件加工的时间,大大提高了劳动生产率,有效地降低了劳动强度。

Abstract
With the improvement of the machining accuracy, in order to reduce the positioning error and improve the machining accuracy, manufacturing precision of the fixture requirements increase. In order to meet the needs of different industries and economy, clip has different models, and the accuracy of criteria for selection of different grades. The versatility of the fixture directly affect the economy, module, modular fixture system uses only fixturing system anization, reconstruction and expansion of the function is strong, and has a wide application range, good versatility, high utilization rate of the fixture, ponents, makes the clamp of mon good, ponents and fine, low matching costs, economic use only the promotion value.
This design bined with the actual production, universal fixture cannot meet the requirements of production, and specifically designed for a milling fixture, including fixture scheme, method of clamping and tool programs, clip and location specific keys of design and machining precision of the analysis.
The utility model has the advantages of good precision, strong pertinence, mainly used for processing fork drilling, expanding 22 spline bottom part operations. The clamp with clamping force device, has the characteristics required by the modern machine tool fixture, and precision, and can effectively reduce machining time and auxiliary time, greatly improves the labor productivity, ef
