Description

一种缓冲限位柱
技术领域
本发明属于限位装置，特别涉及一种缓冲限位柱。
背景技术
目前在不用滑环的旋转机构中，为了保证装置的安全性，都采用机械限位。一般机械限位都是刚性撞击，而刚性撞击会影响一些系统性能。为避免刚性撞击，一般在限位柱上采用橡胶等缓冲装置，来降低甚至消除机械限位的刚性撞击。使用橡胶的弹性紧紧束缚在限位柱上，有时束缚不紧为了防止脱落，会在限位柱的底部安装一个挡圈。虽然此种方式能够合理的达到缓冲限位的作用，但是橡胶缓冲保护套加工比较费劲，需要做很多工装，而且还要加工挡圈，成本高。
发明内容
为了克服现有技术的缺点，本发明提供一种缓冲限位柱，它结构简单，易加工制造，成本低。
本发明解决其技术问题所采取的技术方案是：限位柱本体的外圆柱面上套有第一层热缩套管，第一层热缩套管与限位柱本体过盈配合。
本发明结构简单，易加工制造，成本低。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1为本发明剖视图。
具体实施方式
如图1所示，限位柱本体1的外圆柱面上套有第一层热缩套管3，第一层热缩套管3与限位柱本体1过盈配合。
所述第一层热缩套管3的外圆柱面上套有第二层热缩套管4，第二层热缩套管4与第一层热缩套管3过盈配合。
为了提高缓冲效果，可继续增加热缩套管层数。
所述第一层热缩套管3的内经为比所述的限位柱本体1的外径大1-2mm。
所述第二层热缩套管4的内经为比所述的第一层热缩套管3的外径大1-2mm。
所述过盈配合的实现方法：将第一层热缩套管3套在限位柱本体1上，用热吹风加热第一层热缩套管3进行热缩，冷却后，第一层热缩套管3紧缩在限位柱本体1上。
同样的方法，可以将第二层热缩套管4紧缩在第一层热缩套管3上。
