The inner hole of the guiding part is provided with a threaded connection hole. The clamping sleeve is provided with a clamping sleeve, the outer circle of the clamping sleeve is matched with the inner hole, the inner hole of the clamping sleeve is matched with the outer circle of the working part, and the clamping sleeve is divided along the circumference direction. Cut into three pieces of independent clamping sleeve unit, clamping sleeve unit and clamping unit unit one by one and fixed by screws. The utility model can be applied to clamping various different workpieces, and the structure is simple, and the collet configuration is reduced.
【技术实现步骤摘要】
多功能外胀紧夹头
本技术涉及一种弹性夹头,具体涉及一种外胀紧式的弹性夹头。
技术介绍
外胀紧夹头用于工件外圆的夹紧,是一种实现自动化内孔、端面加工生产的常用工具。外胀紧夹头由一体结构的夹紧部、联接部和导向部组成,工作原理是通过对夹紧部的外圆锥面的压紧,使开设纵向切断槽的夹紧部产生弹性变形,夹紧部的夹紧内孔对位于夹紧内孔的工件外圆进行夹紧。现有技术中,一种外胀紧夹头只能对应一种工件,对于不同形状尺寸的工件,需要配置很多的外胀紧夹头;另外,对于外圆为锥体的工件,需要夹紧内孔也为锥孔,由于夹紧内孔的深度较浅,所以加工锥孔有难度,外胀紧夹头的设计会变得很复杂;还有,为保证强度和持久弹性,外胀紧夹头一般采用金属材质,这不适合一些特殊要求工件的夹紧。
技术实现思路
鉴于
技术介绍
的不足,本技术的目的旨在提供一种能够适用于各种不同工件的夹紧,结构简单,减少夹头配置的多功能外胀紧夹头。本技术是采取如下技术方案来完成的:多功能外胀紧夹头,由一体结构的夹紧部、联接部和导向部组成,夹紧部具有外圆锥面和夹紧内孔,夹紧部沿圆周方向开设三条纵向切断槽,三条纵向切断槽将夹紧部分割成三瓣独立的夹紧部单元,纵向切断槽贯穿夹紧部整个长度直至靠近导向部,导向部的外圆设有导向滑槽,导向部的内孔设有螺纹连接孔,其特征在于:所述夹紧内孔设有夹紧套,夹紧套的外圆匹配夹紧内孔,夹紧套的内孔匹配工件外圆,夹紧套沿圆周方向被分割成三瓣独立的夹紧套单元,夹紧套单元与夹紧部单元一一对应并通过螺钉固定相接。所述夹紧套的外侧端具有法兰圈,法兰圈也随夹紧套被切割成独立的三瓣,法兰圈贴着夹紧部的外端面设置,法兰圈上加工有所述 ...
