一种机械锁紧油缸可转动的锁紧机构
本技术涉及钢球式机械锁紧油缸的
,具体涉及于一种机械锁紧油缸可转动的锁紧机构。
技术介绍
钢球式机械锁紧油缸使用时,锁紧机构跟随活塞杆轴向移动,钢球在解锁过程中不可避免的会在锁紧零件表面的同一位置产生很深的压痕,降低解锁机构的耐久性,从而降低锁紧油缸的使用寿命。
技术实现思路
有鉴于此,本技术提供了一种机械锁紧油缸可转动的锁紧机构,带动锁紧盖和支撑块发生转动,减轻压痕深度,提高解锁机构的耐久性。本技术采取的技术方案如下:一种机械锁紧油缸可转动的锁紧机构,所述锁紧机构包括锁紧盖、钢球架、钢球、支撑块及螺母;所述螺母与油缸活塞杆固定连接,所述支撑块套装在螺母上并由螺母端面限位,所述支撑块的限位端面上设有切向油槽,所述油槽方向与支撑块套装内孔相切;所述钢球架为阶梯轴,大径部分与油缸缸体内壁固定连接,小径部分设有限制钢球轴向运动的限位孔,且小径部分与油缸缸体内壁预留间隔;所述锁紧盖底面与油缸活塞套装,锁紧盖盖体与所述预留间隔孔轴配合,锁紧盖内圆周面设有螺旋油槽;液压油沿所述切向油槽和螺旋油槽流动,流体压力作用在槽上,使锁紧盖和支撑块发生转动。进一步地,所述锁紧盖盖体内圆周为锥面,大端朝外。有益效果:本技术采用带螺旋油槽和切向油槽的锁紧机构零件,使得每次解锁过程中产生的压痕相对前一次压痕转动一定的角度,多次解锁产生的压痕就会沿解锁机构外表面圆周分散分布,每次的压痕不再重合,大大减小了压痕深度,解决了钢球的压痕问题,将该转动的 ...
