摘　　要：研究了一种新型复合镗杆,包括设有离合器的传动轴和刚性支架。传动轴两端分别由角接触球轴承Ⅰ和滑动轴承悬架在刚性支架上。传动轴上设有数个镗刀的套筒,套筒一端由键和螺钉与传动轴固定联接,另一端由角接触球轴承Ⅱ悬架在刚性支架上。镗刀头由压紧螺钉、调刀楔块和紧定螺钉固定在套筒上。与现有技术相比,采用该镗杆技术,不增加镗杆悬臂长度即可安置多工位镗刀,充分利用现有机床和动力转矩,可实现多级台肩孔同时加工。复合镗杆悬臂的刚度好,加工精度高,大大提高了设备的工作效率。A new type of composite boring bar is introduced, including a clutch shaft and rigid support of boring bar, shaft I respectively by angular contact ball bearing and sliding bearing suspension on the rigid support, its characteristic is that on the drive shaft it is equipped with a number of boring cutter sleeve, the sleeve by the key and the screw at one end connected to the drive shaft are fixed, the other end by the angular contacts ball bearing II suspension on the rigid support. The described ones in the boring cutter by compression screw and adjustable cutter wedge are set on the sleeve. The boring bar technology compared with the existing technology has not increased boring bar cantilever length placed multi-station bor- ing cutter, making full use of the existing machine tools and dynamic torque, effectively solve the problem of the multi-stage shoulder hole processing at the same time, compound boring bar cantilever of good rigidity, high machining accuracy, and greatly improve the work efficiency of the equipment.
