制冷零配件
制冷零配件如(ru)消音器(qi)(qi)排氣(qi)管(guan)美加力涂覆黑(hei)色配件是機器(qi)(qi)組(zu)成的基本要素(su)，機器(qi)(qi)一(yi)(yi)般包括一(yi)(yi)個(ge)或幾個(ge)用來接(jie)收外界能源(yuan)的傳動部(bu)(bu)分(fen)，實現機器(qi)(qi)生(sheng)產智能的執行(xing)部(bu)(bu)分(fen)，把原動機的運動和動力傳遞給執行(xing)部(bu)(bu)分(fen)的傳動部(bu)(bu)分(fen)，保(bao)障機器(qi)(qi)中(zhong)各(ge)部(bu)(bu)分(fen)協調工作的監測與控制系統(tong)構(gou)成，將機器(qi)(qi)進行(xing)進一(yi)(yi)步分(fen)解，可以得到各(ge)類零件。
制冷零配件：
1、基(ji)(ji)準先(xian)(xian)行(xing)：即先(xian)(xian)加工基(ji)(ji)準面，零件在機械加工過程(cheng)中，作為定位(wei)基(ji)(ji)準的外表應首先(xian)(xian)加工出(chu)來，以(yi)便盡快為后(hou)續工序的加工提供精基(ji)(ji)準；
2、劃分(fen)加(jia)工(gong)階段：機械加(jia)工(gong)質(zhi)量需(xu)要高的外(wai)表，都劃分(fen)加(jia)工(gong)階段，一般可分(fen)為粗加(jia)工(gong)、半(ban)精(jing)加(jia)工(gong)和精(jing)加(jia)工(gong)三個(ge)階段。主(zhu)要是為了保證(zheng)消音器排(pai)(pai)氣管(guan)美加(jia)力涂(tu)覆黑色加(jia)工(gong)質(zhi)量;有利于科學應用設備;便于安排(pai)(pai)熱處理工(gong)序;以及便于時(shi)發現毛坯缺陷等；
3、先面(mian)后孔：對(dui)于箱體(ti)、支架和連桿等零(ling)件應(ying)先加(jia)工平(ping)面(mian)后加(jia)工孔。這(zhe)樣就可以以平(ping)面(mian)定位加(jia)工孔，保證平(ping)面(mian)和孔的位置(zhi)精(jing)度，而且對(dui)平(ping)面(mian)上的孔的加(jia)工帶來方(fang)便(bian)；
4、光整(zheng)加(jia)工(gong)(gong)(gong)(gong)主要外表的(de)(de)光整(zheng)加(jia)工(gong)(gong)(gong)(gong)，如研磨、珩磨、精磨、滾(gun)壓(ya)加(jia)工(gong)(gong)(gong)(gong)等，應放(fang)在工(gong)(gong)(gong)(gong)藝路線末尾階段。擬定(ding)(ding)精密零件(jian)(jian)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝路線的(de)(de)一(yi)般(ban)原則,精密零件(jian)(jian)加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝規程的(de)(de)制(zhi)定(ding)(ding)，大體可分為(wei)兩個環節。先要擬定(ding)(ding)消音器排氣管美加(jia)力涂覆黑色零件(jian)(jian)加(jia)工(gong)(gong)(gong)(gong)的(de)(de)工(gong)(gong)(gong)(gong)藝路線，然后再確定(ding)(ding)每一(yi)道(dao)工(gong)(gong)(gong)(gong)序的(de)(de)工(gong)(gong)(gong)(gong)序尺寸、所用(yong)設備和(he)工(gong)(gong)(gong)(gong)藝裝備以及切(qie)削規范(fan)、工(gong)(gong)(gong)(gong)時(shi)定(ding)(ding)額等。
