最近我们参考国外资料并结合我厂实际需要,改进设计了一种结构比较简单的可微动调节镗杆(见附图)。实践证明:不但能保证加工精度,且节约了辅助工时,提高了劳动生产率,现介绍如下,供参考。这镗杆的特点是利用偏心的原理来控制刀头的进刀量。在镗杆如中采用研配镶入滑座6,镗刀借内六角螺钉3固定在滑座6内,由于弹簧7的作用使滑座6通过一颗φ6毫米的钢珠压紧在调节偏心圈1的内壁上。调节偏心圈1的内孔偏心0.5毫米,以圈壁最
Recently, we refer to foreign information and combined with the actual needs of our plant to improve the design of a simple structure of the micro adjustable boring bar (see photo). Practice has proved that: not only can guarantee the machining accuracy, and save the auxiliary working hours, improve the labor productivity, are introduced as follows, for reference. The characteristic of this boring bar is the use of eccentric principle to control the feed of the cutter head. In the boring bar, such as the use of research into the insert 6, boring boring tool by hexagonal screw 3 is fixed in the slider 6, 6 due to the role of the spring slide 6 by a φ6 mm steel ball pressed in the adjustment eccentric 1 on the inner wall. Adjust the eccentric hole eccentric hole 1 0.5 mm eccentric to the most ring wall
