我们在Y 7150型磨齿机上的定转数间歇机构和丝杠处,安装一套分齿装置后,成功地磨削出不同模数的齿条。加工原理及分齿装置:按成型法加工,砂轮被修成锥形以构成假想齿条的齿面。齿条位置固定不动,机床立柱1带着砂轮向前移功至全齿深,磨齿后退出。工件按固定节线移动齿距,如此循环。如图1所示,分度开始时将离合器5接通,按动分齿装置电钮,使电磁铁19产生牵引力。通过联接杆20使
We Y7150 type gear grinding machine on the number of intermittent institutions and the screw at the installation of a set of teething device, the successful grinding of different modulus rack. Processing principle and sub-tooth device: According to the molding method, the grinding wheel is tapered to form the tooth surface of the imaginary rack. The rack position is fixed. The column 1 of the machine tool moves forward with the grinding wheel to the full depth of the tooth, and retracts after grinding. The workpiece moves by a fixed pitch pitch, so cycle. As shown in FIG. 1, the clutch 5 is turned on at the beginning of the indexing, and the electric button 19 is pressed to make the electromagnet 19 generate the traction force. Through the coupling rod 20 to make
