用w100型万能分度头和配套的顶尖座,每装夹一次套形零件(长64毫米),必须松开顶尖座的两个压紧螺钉,卸下工件时还需向后拉动顶尖座。用这种方法加工零件,不但浪费了辅助时间,而且定位精度也难保证。为此,我们对原顶尖座进行了改进(如图所示)。向右旋转手柄9,在螺杆7的作用下,套筒4及顶尖5向后移动,工件被松开。同时向右旋转快速手柄8,并向后拉动。快速套筒3在导向螺钉6
With w100-type universal indexing head and supporting the top seat, each clamping a sleeve-shaped parts (length 64 mm), you must loosen the top two compression screws, remove the workpiece need to pull the top seat back. Using this method of processing parts, not only wasted auxiliary time, and positioning accuracy is difficult to guarantee. To this end, we have improved the top seat (as shown). Turn the handle 9 to the right, under the action of the screw 7, the sleeve 4 and the top 5 move backward, and the workpiece is released. Rotate Quick Handle 8 to the right and pull backwards. The quick sleeve 3 is on the guide screw 6
