在普通车床上加工多品种、形状复杂、工艺性要求高的零件是有一定困难的。这里介绍一种在普通车床上使用的多功能刀架,即能保证工件的加工精度及其他要求,又能提高效率。刀架结构如图所示(其尺寸是用在C620、C6140及C6150普通车床上)。该刀架是夹在普通车床的刀架内,可以不转动刀架,一次工序能加工内外螺纹、内外圆的各挡尺寸或锪内孔、攻丝或切槽等。根据产品零件形状和尺寸,可以相应改变刀架尺寸,根据机床大小和中心高低设计刀架的具体尺寸,但所有形状和结构基本一致。刀架体上的φ25~(+0.027)孔,既可装自制过渡套,过渡套外圆配φ25~(+0.027)孔,内锥为标准2~#英氏,可放钻头,钴锪零件
In the ordinary lathe processing variety, shape complexity, high technological requirements of the parts is a certain difficulty. Here to introduce a multi-functional turret used in general, that can guarantee the accuracy of the workpiece and other requirements, but also improve efficiency. Tool holder structure as shown (the size is used in C620, C6140 and C6150 ordinary lathe). The knife holder is caught in the ordinary lathe turret, you can not rotate the turret, a process can be processed inside and outside the thread, the internal and external dimensions of the block or 锪 hole, tapping or grooving. According to the shape and size of the product parts, the size of the tool holder can be changed accordingly. The specific dimensions of the tool holder are designed according to the size of the machine and the height of the center, but all the shapes and structures are basically the same. Tool holder body φ25 ~ (+0.027) hole, either self-made transition sleeve, transition sleeve with φ25 ~ (+0.027) hole, the inner cone for the standard 2 ~ # British, can be put drill, cobalt 锪 parts
