摘要
针对液压支架双伸缩立柱中缸采用普通工艺加工存在的问题,参考了带式输送机滚筒弹性涨套的定位原理,研制了一种新型液压支架双伸缩立柱中缸加工定位卡装置,主要由顶盘和弹性涨套组成。该定位卡装置经实际应用,显著地提高了中缸加工的成品率和质量,降低了工人的劳动强度和加工成本,同时使立柱密封面研磨损坏而引发设备故障的概率也大幅降低。
In view of the problems existing in the middle cylinders on double telescopic columns of hydraulic supports during ordinary process,referring to the locating principle of the elastic expansion sleeve of the belt conveyor drum,a new type of hydraulic support double telescopic column middle cylinder processing positioning card device is developed,which mainly composed of the roof and the elastic sleeve.The locating card device has remarkably improved the finished product rate and quality of the middle cylinder processing,reduced the labor intensity and the cost of the processing,at the same time,the failure probobitity of the sealing surface of the column has been greatly reduced.
