我厂加工的干式铸铁气缸套,内孔的尺寸是在M4216老式珩磨机上加工的。操作时,必须提前把干式铸铁气缸套压入随行套里,珩磨时靠油缸压紧随行套。测量工件时,必须松开夹紧,把随行套从夹具里拿出来测量。加工一个工件得反复把随行套从夹具里拿出来好几次测量,很麻烦。这种操作方法满足不了生产的需要,而且气缸套的壁厚差也往往达不到工艺要求。为此我们设计了可移动夹具珩磨气缸套,提高了生产效率,工件的尺寸精度也达到了工艺要求,效 I plant processing of dry cast iron cylinder liner, the hole size is processed in the M4216 vintage honing machine. Operation, must be in advance of the dry cast iron cylinder liner into the accompanying sleeve, honing cylinder by pressing the accompanying sets. Measurement of the workpiece, you must release the clamp, the accompanying sets from the fixture to measure out. It takes a lot of measurement to take a few measurements from the fixture in order to process a workpiece. This method of operation can not meet the needs of production, but also poor cylinder wall thickness often fail to craft requirements. To this end, we designed a movable clamp honing cylinder liner to improve production efficiency, the workpiece dimensional accuracy has reached the process requirements, efficiency
