该夹具附加一个小型液压站配在X62W铣床上,用于大批量加工195型柴油机起动齿轮轴的螺旋槽(图1)。经过几年在南宁机械厂生产考验,加工出近10万个零件,工件尺寸符合图纸要求,光洁度在?4以上,班产量250～300件。液压系统见图2。一、工作原理当压力油进入油缸后腔时(图3),活塞杆上的齿条作直线运动,与齿条啮合的齿轮15在原位作旋转运动,由键6带动轴 The fixture is attached to a small hydraulic station for use with the X62W milling machine for high-volume machining of helical grooves in the starting gear shaft of a Type 195 diesel engine (Figure 1). After several years in Nanning Machinery Factory production test, processing nearly 100,000 parts, the workpiece size in line with the requirements of the drawings, finish in? 4 above, the class output of 250 to 300. Hydraulic system shown in Figure 2. First, the working principle When the pressure oil into the cylinder after the cavity (Figure 3), the piston rod rack for linear motion, meshing with the rack gear 15 in place for rotation, the key shaft 6
