这是一种利用靠模范成导程的分度头。适用各种铣床、刨床、插床;特别是用于自动、半自动机床时,有相当准确的随动性,还可以与相应的磨床配合进行直接磨削直槽和螺旋槽,并具有分度快、调整方便、无级调导程等特点,最适应工具加工使用。结构:由分度头和靠模两部分组成。分度头(图1)由齿条、双联齿轮12、13、齿轴6、主轴8、主体4、分度盘20、定位销21、转臂26等主要件组成。主体4上(除与齿轴6的装配孔外)的轴孔都装有e=0.25的偏心套,以调整齿部啮合间隙,减小顺铣时主轴与靠模之间的空动、分度盘与齿
This is a type of indexing head that utilizes the index head. For a variety of milling machines, planer, slotting; Especially for automatic, semi-automatic machine, there is a very accurate follow-up, but also with the corresponding grinding machine with direct grinding straight slot and spiral groove, and with indexing fast, Easy adjustment, stepless adjustment process characteristics, the most suitable tool for processing. Structure: Divided by the head and by the two parts of the module. Indexing head (Figure 1) by the rack, double gear 12, 13, pinion 6, the main shaft 8, the main body 4, indexing plate 20, positioning pin 21, the main arm 26 and other components. The main body 4 (except for the mounting hole with the pinion 6) is equipped with an eccentric sleeve with an e = 0.25 to adjust the meshing clearance of the teeth and reduce the lost motion between the spindle and the master in the down-milling Dial and tooth
