1、压缩机箱体夹具设计摘要零件的加工工艺编制,在机械加工中占有非常重要的地位,零件工艺编制得合不合理,这直接关系到零件最终能否达到质量要求;夹具的设计也是不可缺少的一部分,它关系到能否提高其加工效率的问题。因此这两者在机械加工行业中是至关重要的环节。本次设计的是压缩机箱体加工工艺以及夹具的设计,压缩机主要作用是把低压冷媒汽体吸进压缩成高压汽体----冷却循环,使部分动能转化为压力能从而提高汽体的压力。压缩机箱体则是承载这个压力和连接各零部件,因此要求箱体能够承受压力,以及箱体与其他零部件的密封性,在编制加工
2、工艺时,要考虑到各个接触面的各项精度以及形状与位置公差等。在设计加工箱体斜面上的螺纹孔专用夹具时,由于孔是自由公差,所以为了缩短加工时间,采用两个斜面挡块来使箱体工件定位,再使用两铰链支座,使得装夹工件就方便了,斜面挡块的与水平位置倾斜14°,保证了被加工斜面在水平位置,使用钻模以及钻模套来准确的定孔的加工位置,有钻模套加工孔无需画线定位,直接就可以加工,提高了加工效率。4ABSTRACTTheparttreatinghandicraftestablishment,occupiesveryimporta
