分度开槽夹具
本技术涉及一种夹具,具体的说是一种能够实现分度开槽的夹具,属于机加工设备
技术介绍
随着机械行业发展,为了适应各个行业精密零件的需求,对于不同要求的零件加工,夹治具变得尤为重要,机器成本及人工成本不断的升高,企业对加工周转周期及其成本的控制也在不断的提高。机械自动化不断发展,这就对机加工某一部位,不同方位的开槽的加工方法有了一个更高的挑战,分度的准确性和开槽速度的快慢也提出了更高的要求,因此一些零件某部位快速分度开槽直接影响着零件的周转周期及零件成本的管控。现有技术中,分度开槽主要通过两种方式实现:1.直接在机器上运用机械自动开槽,这样不但占用大量的机械,而且浪费机器成本;2.直接用多人工分度开槽,如一个人做0°和180°的开槽,一个人做90°和360°的开槽,浪费多个人工成本不说,且多次装夹,角度准确性得不到确切的保障。在分度开槽的实际加工过程中经常出现零件加工慢耽误交期,且分度不准确,报废率升高等其他加工过程中造成零件尺寸及外观不良,直接影响零件的品质,造成不良品的急剧上升。
技术实现思路
本技术的目的在于克服上述不足之处,从而提供一种分度开槽夹具,能够实现快速装夹、精密分度,提高了分度开槽的加工效率,保证零件的质量,使加工成本和周转周期都得到了有效的改善。按照本技术提供的技术方案,分度开槽夹具包括下支座、上支座、弹簧夹套和分度钢珠,其特征是:上支座和下支座上下分布设置,上支座和下支座之间设有平面轴承;弹簧夹套下端设有螺杆部,螺杆部从上到下依次穿过上支座和下支座,螺杆部和上支座之间设有滚珠轴承,螺杆部和下支座之间通过螺纹连接;上支座 ...
