五角刀架是立车经常发生振动故障的一个部件。根据对多台立车修复的经验,认为主要是五角刀架受力分配不合理和调整不当造成的。 五角刀架必须具有良好的轴向定位、径向定位和抗旋转力。机床在经过一个时期的使用后,由于实际受力的作用和各受力零件自身的硬度不同,因而产生不同 Pentagon turret is often a vertical car vibration failure of a component. According to the experience of repairing multiple vertical lathes, it is mainly caused by the unreasonable stress distribution and improper adjustment of the pentagon turret. Pentagon turret must have good axial positioning, radial positioning and anti-rotation force. Machine tool after a period of use, due to the actual role of the force and the strength of the various parts of the different hardness, resulting in different
