锁紧装置工作原理：
只要液压释放压力加到EE离合器上，活塞杆就能在两个方向自由运动。如果这释放压力解除，蓄积在弹簧上的力释放出来并使活塞杆被锁定。由于有意图地减低压力或者是由于一个应急开关的闭合，电源掉电和系统损坏而造成的液压系统失压。锁紧可以持续的时间是无限的并无须供电。锁紧由释放压力打开同时活塞杆又能自由运动。由于内力的作用短暂的在短行程的部位超载是可能，但不会毁坏活塞杆和锁紧装置!
应用领域：冶金设备、数控机床、模具设备以及*生产线的机械锁紧。

机械自动锁紧装置一种新型液压油缸机，包括工作油缸(2)、*纵杆(15)及锁紧部件，锁紧部件是由固定座(1)及置于固定座空腔内的斜锲(4)、滑动块(6)、弹簧(5)、摩擦片(7)组成，工作油缸上、下两端为圆锥面，该工作油缸置于固定座中心孔内，滑动块、斜锲有相对应的斜面(12、13)，两斜面贴合并可相对移动，滑动块的另一端联接着摩擦片，该摩擦片(7)是与工作缸外径相适配的弧形件，从径向的两侧贴紧工作油缸，在其贴合面上，设有与工作油缸上、下锥面相对应的斜面(10、11)，在*纵系统控制下，通过*纵杆的上、下运动，靠工作油缸的负载力及自重力使各斜面贴合，将工作油缸分别锁定于工作状态及撤收状态，该装置可排除液压系统油液渗漏对锁紧精度的影响，适用于需要锁紧的各种液压油缸，更适用于对锁紧位置精度要求高，保持时间长的液压装置中。

：主要是看用机械式的，还是液压式，还是*锁紧。各类型所用零部件都不一样，液压跟*的组要是气缸，液压缸推动夹头实现锁紧，机械式的组要是偏心锁紧把手跟辅助挡块，等

主要由径向承载件、轴向承载件、锁紧装置、密封装置等部分组成。其中,锁紧装置在整套油膜轴承中起着重要的作用。它用来将径向承载件等紧固在轧辊上,使轴承正常工作。锁紧装置的快速装卸功能及锁紧的可靠性是影响现场装配效率及轴承可靠性的关键因素之一。如果锁紧装置锁紧可靠性差,用于固定锁紧板与锁紧螺母的螺栓松动,将会导致锁紧板、卡环脱落,迫使轧机停产,给钢厂造成巨大的经济损失。

锁*装置是机械装置，内置在气缸内部的，我们当时用的是40mm缸径的，具体最大、最小缸径能做到多少，就不太清楚了。有些机构如平面四杆机构，凸*机构，螺纹等都有自锁功能。机械中的锁紧，一般都是用自锁实现的
