行星铣内螺纹专用机床(图1)用来铣削乳化液泵阀体上的M80×2及M45×2内螺纹孔。提高生产效奉10陪。操作实现半自动化,螺纹光洁度达到6,精度提高,质量稳定。 加工原理如2图所示。刀杆以n_1=1450转/分旋转,自转一周中在S_1S_2一段孤长内进行切削。刀杆在高速自转的同时,又以n_2=4.5转/分的速度绕O_2公转。当刀杆公转一周动力头即向前移动一个螺距,也就加工出一扣螺纹。 Planetary milling internal thread special machine (Figure 1) is used to mill the M80 × 2 and M45 × 2 female tapped holes on the body of the emulsion pump. Improve production efficiency 10 accompany. Semi-automatic operation, thread finish 6, accuracy, quality and stability. Processing principle as shown in Figure 2. Arbor with n_1 = 1450 rev / min rotation, a week in the rotation S_1S_2 in a long period of cutting. Arbor in the high-speed rotation at the same time, with n_2 = 4.5 rev / min speed around O_2 revolution. When the arbor one revolution of the power head that is moving forward a pitch, it also processed a buckle thread.
