Abstract

本发明涉及机械连接领域，特别涉及一种套筒锁紧装置。套筒锁紧装置，由内向外依次包括固定导向管、衬套、可移动套筒、和锁紧环，所述可移动套筒外表面有孔，所述孔内放置有滚珠，所述锁紧环上切有偏心内圆槽，所述偏心内圆槽相对所述锁紧环外圆的中心有偏心量，所述滚珠部分位于偏心内圆槽内。当可移动套筒安装到要求位置后，为了使其固定，转动锁紧环，偏心内圆槽将滚珠压向衬套和固定导向管，就可以将可移动套筒锁紧。

Description

套筒锁紧装置
技术领域
本发明涉及机械连接领域，特别涉及一种套筒锁紧装置。
背景技术
锁紧机构是一种广泛使用在多种装置中的机构，用于将可动零部件固紧在所需位置上，锁紧机构一般为螺纹锁紧，但是螺纹锁定并不十分可靠，螺钉会反转或松动，时间长会影响部件之间连接的可靠性。
发明内容
本发明的目的是提供一种连接可靠、结构合理的套筒锁紧机构。
本发明的技术方案如下：套筒锁紧装置，由内向外依次包括固定导向管、衬套、可移动套筒、和锁紧环，所述可移动套筒外表面有孔，所述孔内放置有滚珠，所述锁紧环上切有偏心内圆槽，所述偏心内圆槽相对所述锁紧环外圆的中心有偏心量，所述滚珠部分位于偏心内圆槽内。
当可移动套筒安装到要求位置后，为了使其固定，转动锁紧环，偏心内圆槽将滚珠压向衬套和固定导向管，就可以将可移动套筒锁紧。
附图说明
下面结合附图和具体实施方式对本发明作进一步详细的说明。
图1为本发明的结构示意图；
图2为图1的A-A剖视图。
具体实施方式
如图1和图2所示，本发明的套筒锁紧装置，由内向外依次包括固定导向管1、衬套5、可移动套筒2和锁紧环4，所述可移动套筒2外表面有孔，所述孔内放置有滚珠3，所述锁紧环4上切有偏心内圆槽6，所述偏心内圆槽6相对所述锁紧环4外圆的中心有偏心量，所述滚珠3部分位于偏心内圆槽6内。当可移动套筒2安装到要求位置后，为了使其固定，转动锁紧环4，偏心内圆槽6将滚珠3压向衬套5和固定导向管1，就可以将可移动套筒2锁紧。

Claims (1)

1.套筒锁紧装置，其特征在于，由内向外依次包括固定导向管、衬套、可移动套筒、和锁紧环，所述可移动套筒外表面有孔，所述孔内放置有滚珠，所述锁紧环上切有偏心内圆槽，所述偏心内圆槽相对所述锁紧环外圆的中心有偏心量，所述滚珠部分位于偏心内圆槽内。
