目前,铣床上所用的锥柄立铣刀的安装方法,大部分靠尾部锥柄用拉杆拉紧定位。装拆极为不便。本文介绍刀杆快换夹头,是我们在吸收德国先进技术的基础上设计的,已在合作生产的HVC-4数控置铣床上得到了应用。实践证明,其使用安全可靠,装卸方便,大大节省了装卸刀时间。其结构及工作 At present, the taper shank milling cutter used on the end of the installation of the cutter, most of the taper shank with the tail taut position. Assembly and disassembly is extremely inconvenient. This article introduces a quick changer Chuck, which is based on our absorption of Germany’s advanced technology and has been applied in the co-production HVC-4 CNC milling machine. Practice has proved that its safe and reliable, loading and unloading convenient, greatly saving the handling knife time. Its structure and work
