φ1650圆锥破碎机由于震动,造成竖轴顶端螺纹位置严重磨损而使开缝螺母松动,为了确保设备安全运转,尽快修复竖轴,节约备件费用,我厂自制了一台大直径螺纹绞丝装置(如图)。使用这种绞丝装置,可争取时间,避免加工上的困难。可就地修复竖轴螺纹,修复后的螺纹直径,稍有些缩小,但不要紧,可将废旧开缝螺母内孔给予堆焊后与竖轴绞制好的螺纹进行配车,这样加工出来的螺母完全符合装配松紧要求。大直径螺纹绞丝装置,可直接支承在轴顶端上,刀架上装有刀具,还有与螺纹有关的调节丝杆,当转动手柄时,整个刀架可沿着轴套方向上下移动,螺纹就绞制而成了。
φ1650 cone crusher as a result of vibration, causing the vertical axis of the top thread position serious wear and tear caused by loose nut, in order to ensure the safe operation of equipment, as soon as possible to repair the vertical axis, saving spare parts costs, I plant a homemade large-diameter screw thread device Figure). Use of this twisted wire device, you can gain time to avoid processing difficulties. Repair on-site vertical axis thread, the thread diameter after repair, a little smaller, but it does not matter, the waste can be given to open the inner hole of the slotted nut and vertical shaft stranded good thread with the car, so processed nuts In full compliance with the assembly requirements. Large-diameter thread skein device, can be directly supported on the top of the shaft, the tool holder is equipped with a knife, as well as thread-related adjustment screw, when the handle is turned, the entire tool holder can be moved up and down along the sleeve, thread Twisted and made.
