链式刀库结构紧凑,容量大,在机床制造中用得很多。但是刀库运行时,输送链会因磨损而下垂,致使换刀位置中的刀座定位有误差。右图所示是消除这缺陷的定位装置,一个液压缸和两根撑杆把在换刀位置的刀座固定在链轮上。撑杆在刀库机架中平稳移动,每根撑杆的前端有两个滚轮,它们压紧在输送链的滚子上,使刀座精确定位。输送链下垂现象被消除,为避免轴向定位误差
Chain knife magazine compact structure, large capacity, used in machine tool manufacturing a lot. However, when the tool magazine is in operation, the conveyor chain will sag due to wear and tear, resulting in an incorrect positioning of the tool holder in the tool change position. The figure to the right shows the positioning device to eliminate this defect. A hydraulic cylinder and two struts hold the tool holder in the tool change position to the sprocket. The struts move smoothly in the magazine rack, with two rollers at the front of each strut, which press against the rollers of the conveyor chain to precisely position the seats. Conveyor chain droop phenomenon is eliminated, in order to avoid axial positioning error
