该机构主要由斜块、钢球和顶杆组成(见图),其工作原理如下:卸刀时,用扳手拧动M16×1.5的螺钉,推动斜度为1:4.8的滑块6向前移动.这时钢球4沿斜面向左推动顶杆3移动,因主轴的反作用力,使锥柄刀杆轻松脱落.然后,拧动螺钉7向后退,滑块6在弹簧5的作用下复位.卸刀杆时,限位螺钉2使顶杆不会从孔中滑出.由于刀杆是锥柄的,楔紧力大.此种快换机构的结构就比拧动螺纹套式的拆卸更为方便.它不用配套各种不同规格的专用扳子,只需一把活动扳子.因此,用于
The mechanism is mainly composed of inclined block, steel ball and ejector rod (see picture). Its working principle is as follows: When unloading the knife, use a wrench to tighten the M16 × 1.5 screw and push the slider 6 with a slope of 1: 4.8 to move forward Then the ball 4 along the inclined surface to push the mandrel 3 to move left, due to the spindle reaction force, so that the taper shank arbor easily fall.Then screw the screw 7 to back, the slider 6 in the spring 5 reset . When the cutter bar is unloaded, the stopper screw 2 will not allow the ejector pin to slide out of the hole. Because the cutter bar is taper shank, the wedging force is large. The structure of such a quick-change mechanism is smaller than that of the screw- More convenient. It does not need to support a variety of different specifications of the special wrench, just an activity wrench. Therefore, for
