我厂对M36×4盲孔螺纹、M42×4.5通孔螺纹的加工,在Z35摇臂钻床上,采用行星齿轮传动攻丝饺孔工具,效果较好,扩大了钻床攻丝、铰孔范围,确保了产品质量,较手动攻丝提高工效3～4倍。工具结构如图所示。当钻床主轴带动偏心轴22逆时针旋转时,因内啮合齿轮存在齿数差,使外齿动轮17在内齿定轮16中除作逆时针公转外,还产生与偏心轴为1:8的顺时针自转,滑块15把外齿动轮的自转传给外套12,
I plant M36 × 4 blind hole thread, M42 × 4.5 through-hole thread processing, Z35 radial drilling machine, the use of planetary gear drive tapping hole tool, the effect is better, expanding drilling tapping, reaming range, To ensure product quality, more effective than manual tapping 3 to 4 times. Tool structure as shown. When the drilling spindle drives the eccentric shaft 22 to rotate counterclockwise, the external gear 17 is caused to rotate in the internal toothed wheel 16 in counterclockwise rotation due to the difference in the number of teeth of the internal gear, and a 1: 8 Rotating the hour hand, the slider 15 to the outer wheel gear rotation 12,
