我厂生产的JB23-63型压力机中的调节螺杆、球头座、球头盖零件,要求球体部份接触面积不少于50％。为此设计了研磨专用装置(如图所示)。动力由电机(J02-12-4/T2,1380r/min,0.8kW)传给两级蜗轮减速箱(传动比是2/24×2/24),通过连接套使工件调节螺杆转动,其转速n=1380×2/24×2/24=9.6r/min。另一方面,曲拐与蜗轮减速箱的第一级传动相连,其转动通过接杆的作用,使摆动盘摆动。摆动速度v=1380×2/24=115次/min,摆动角α=0°～9°。工件球头盖、球头座用螺钉相连,可使两者
I plant JB23-63-type press in the adjustment screw, ball seat, ball cap parts, the required ball contact area of not less than 50%. Designed for this purpose grinding device (as shown). Power from the motor (J02-12-4 / T2, 1380 r / min, 0.8kW) to the two-stage worm gearbox (transmission ratio is 2/24 × 2/24), through the connecting sleeve so that the workpiece adjustment screw rotation, the speed n = 1380 × 2/24 × 2/24 = 9.6 r / min. On the other hand, the bellcrank is connected with the first stage transmission of the worm gear box, and the rotation of the swinging plate is caused by the action of the connecting rod to make the wobble plate swing. Swing speed v = 1380 × 2/24 = 115 times / min, swing angle α = 0 ° ~ 9 °. Workpiece ball cover, ball seat with screws connected to both
