经过近20年的使用考验,几经产品转换,证明这些成组夹具的性能稳定可靠,经济效果显著。机械工厂中车床(包括立车)所占的比重最大,而法兰、壳体及其它不规则零件在车床上的成组加工时装卡多较困难和费力,但一般见诸于资料的成组夹具以铣、铇、钻、镗床用的较多,车床及立车用的既少,又不理想。因此我厂自1963年开展成组加工试点以来重点发展车床类成组夹具。该类夹具的共同特点是:
After nearly 20 years of use test, after several product conversion, proved that the performance of these groups of fixtures stable and reliable, significant economic effect. The lathe (including the vertical lathe) occupies the largest proportion of machinery factory, and the flange, shell and other irregular parts in the lathe group processing fashion card more difficult and laborious, but generally seen in the data group Fixture to milling, 铇, drilling, boring machine with more lathes and vertical cars with less, but not ideal. Therefore, I plant since 1963 to carry out group processing pilot focus on the development of lathe group fixture. Common features of this type of fixture are:
