本装置可用于普通车床刀架上,作60m/min以上的高速车削,并能自动退刀,一般能加工圆柱螺纹和锥度管牙螺纹(锥度在30°以内)。采用切削的刀片,系重新改磨的YT15或798-3K1305E3的可转位刀片。现将其结构介绍如下: 刀杆体1装夹在车床刀架上,导程板16用销轴17与导板15连接,再通过销轴13、螺母14与固定在尾架套筒上的支架25连接。进刀时,手动或机动移动大拖板,使顶杆4沿着导程板16滑动。由于小刀杆3用螺钉固定在同顶杆4相连接的长方形滑块2上,从而使车刀进行仿形进给。导程板16可按照工件的锥度制备、更换。另外,导程板上有若干只插销轴17的调节孔,是用以调
The device can be used on ordinary lathe turret, for high-speed turning 60m / min or more, and can automatically retract the knife, the general processing cylindrical thread and taper pipe thread (taper within 30 °). Using a cutting insert, a reshaped YT15 or indexable insert of the 798-3K1305E3. Now the structure is introduced as follows: a cutter body 1 mounted on the lathe turret, the guide plate 16 with the pin 17 is connected with the guide plate 15, and then through the pin 13, the nut 14 and the bracket fixed to the tailstock sleeve 25 connection. When feeding, the large carriage is manually or movably moved so that the ejector rod 4 slides along the guide plate 16. Since the knife bar 3 is screwed to the rectangular slider 2 connected to the jack 4, the turning tool is subjected to the copying feed. The lead plate 16 can be prepared and replaced according to the taper of the workpiece. In addition, the guide plate has a number of bolt hole 17 adjustment hole is used to adjust
