针对ZY-650钻机动力头对中差的问题,设计了车加工的定心工装,以提高加工精度,改善动力头的总体功能性能。加工结果表明,该方法可以有效改善驱动套同轴度精度,加工精度完全符合期望要求。
In view of the difference of the power head of the ZY-650 drilling rig, a centering tool for the machining is designed to improve the machining accuracy and improve the overall functional performance of the power head. The machining results show that this method can effectively improve the concentricity accuracy of the driving sleeve and the machining accuracy fully meets the expectation requirements.
