C61100车床溜板箱中有两只90°齿形、120牙的端面直齿齿牙盘(见图1),以前是在平铣上,用分度盘进行人工分度来铣削端面齿的。每加工一只齿牙盘,就要120次的人工分度,还不包括每牙铣好后的退刀。因此,操作工人的劳动强度大,生产效率低。还不易保证质量。后来,我们对机床部分传动链进行了改装,实现了端面直齿齿形自动分度连续切削,大大地减轻了操作工人的劳动强度,生产率提高50％以上,质量也有很大的提高。刀具到工件的自动分度传动链如图2所示。铣床主轴上装有一片2牙的专用铣刀1,主轴另一端装有链轮5,把运动传给链轮6,再通过万向接头14接入1/90分度盘,即能实现工件的自动分度。传动链计算
C61100 lathe in the box with two 90 ° tooth profile, 120 tooth end face straight tooth gear (see Figure 1), the previous is in the flat milling, with indexing plate manual indexing to mill face tooth. Each processing a tooth plate, it is necessary 120 times the manual indexing, does not include each tooth milling after the retraction. Therefore, the workers are labor-intensive and their production efficiency is low. Still not easy to ensure quality. Later, we modified the part of the transmission chain of the machine to realize continuous automatic taper cutting of the face straight tooth profile, which greatly reduced the labor intensity of the workers. The productivity increased by more than 50% and the quality was greatly improved. Tool to the workpiece automatic indexing drive chain shown in Figure 2. Milling machine spindle is equipped with a piece of 2-tooth milling cutter 1, the other end of the spindle sprocket 5, the movement is passed to the sprocket 6, and then through the universal joint 14 access 1/90 sub-dial, which can achieve the workpiece Automatic indexing.
