摘要
在各种不同的用途,机械制造业它被广泛处理所固定物体,以便占据在正确的位置的处理装置,称作待处理的器械。因此,机械加工,装配,检验,或夹具,焊接,得到了广泛的热处理等冷,热加工和运输工作期间使用与否。但是,它是被最广泛使用的夹具,夹具金属切削机床,我们正在谈论的设备。这是产品,高收益,低成本的,复杂的精密部件,以确保现有的设备,或工人的全部潜力来处理技术,减少繁重的体力劳动,质量已经发挥了重要作用它是能够掌握。因此,它是重要的技术措施的设计,采用了模具和夹具,促进生产的快速发展。出于这个原因,在本设计中,夹具和设计的固定装置的选择。
本文围绕中心钻夹具的设计。钻头部分的部分,首先通过夹具的设计实践使我们能够有一个初步的了解,尤其是夹具设计更深刻的理解。然后,分析了夹具的设计,选型的指导下进行。选定的夹具后。通过查阅相关书籍和设备,设计相关的加工夹具的设计过程。确认的相关文件完成后。为了完成该夹具的整体设计,请参考相关信息。
