我厂有一台MJ4216珩磨机,磨头胀缩需用手动控制,我厂生产的等离子气缸套采用珩磨抛光内表面,生产节拍紧,要求效率高,磨头手动胀缩费时费力,满足不了节拍的要求,我们对磨头进行了改造,增加液压胀缩装置,解决了这一问题。 1.液压胀缩装置的结构 液压胀缩装置的结构如图1所示,主轴接杆1和油缸3用螺钉连为一体,油缸下端挂接珩磨头,通过活塞4的运动压缩磨头内的胀杆实 I plant a MJ4216 honing machine, grinding head expansion and contraction required manual control, I plant the production of plasma cylinder honing and polishing the inner surface, the production beats tight, requiring high efficiency, grinding head manual expansion and contraction time-consuming and laborious, can not meet the beat Requirements, we modified the grinding head, increase the hydraulic expansion and contraction devices to solve this problem. 1. Structure of hydraulic expansion and contraction device Structure of hydraulic expansion and contraction device shown in Figure 1, the main shaft connecting rod 1 and cylinder 3 with screw as a whole, the lower end of the cylinder mounted honing head, the movement of the piston 4 compression within the grinding head Expansion rod real
