在普通卧式镗床上,装卸镗刀杆是件频繁而麻烦的事。为减少辅助工时和主轴锥孔的磨损,研制出一种快换夹头(图1)。它是由三个滚柱1、偏心套2、两个端盖3、两个挡圈4、圆柱销5和主体6组成。三个圆头滚柱1是均布在主体6的长孔槽中,而孔槽的底部应不使滚柱1掉出。偏心套2与滚柱1在长槽孔中处于相互对应的位置,并特制出三个弧形凹沟(图1A-A),用
In the ordinary horizontal boring machine, loading and unloading boring bar is a frequent and troublesome thing. In order to reduce the auxiliary working hours and spindle taper wear, developed a quick change chuck (Figure 1). It is composed of three rollers 1, eccentric sleeve 2, two end caps 3, two retaining rings 4, a cylindrical pin 5 and a main body 6. The three round head rollers 1 are evenly distributed in the slot of the main body 6, and the bottom of the slot should not allow the roller 1 to fall out. The eccentric sleeve 2 and the roller 1 are located at positions corresponding to each other in the slots, and three arc-shaped grooves (FIG. 1A-A) are specially designed for
