如图所示为机夹四刃刀片车刀,由刀体2和装于其上直角槽内的车削刀片1组成。刀片车刀体上夹紧的方法为:在拧螺钉3时夹紧力经圆柱形销子传递给特型销子5,后者转动,并用球形头部作用于车削刀片1上形成压紧力矩。此时,刀片以自己的支承表面压紧刀体2的支承表面,并用侧表面压入其槽的角中,以保证刀片固定在刀体上增加强度。车削时均匀的切削力与压紧力的方向相重合,由此提高了刀片的固定强度。这种车刀可与钎焊结构车刀的使用规程相同。
As shown in the picture is a four-blade machine tool holder blade, the cutter body 2 and mounted on the upper right-angle groove turning insert 1 composition. The method of clamping the cutter body is as follows: when the screw 3 is tightened, the clamping force is transmitted to the special pin 5 via the cylindrical pin, which rotates and uses the spherical head to act on the turning insert 1 to form a tightening torque . At this point, the blade presses against the bearing surface of the body 2 with its own bearing surface and is pressed into the corner of its groove with the side surface to ensure that the blade is fixed to the body and increases the strength. The uniform cutting force during turning is coincident with the direction of the pressing force, thereby increasing the fixing strength of the insert. This type of turning tool can be used in the same way as a brazed turning tool.
