我厂机加车间小批量生产MP-0021接头和MP_5-0021三通接头,其毛坯如图1: 被加工后零件如图2: 其工艺路线是钳工去毛刺,按图划线(中心和圆),然后上车床,用四爪卡盘按线找正,找正后再车削,这样每个零件都要划线,一批零件好几百,钳工加工起来工作量太大,而效率很低(车:每件都要找正),质量也不易保证,基于以上情况,车工谭刚生同志,利用料头制出了一套多用途夹具如图3:
MP-0021 connector and MP_5-0021 tee connector of MPC-0021 are manufactured in small workshop in our factory. The blank is as shown in Fig. 1: The machined part is as shown in Fig. 2: The process route is the fitter deburring, ), And then on the lathe, with a four-jaw chuck according to the line to find positive, find and then turning, so that each part to be crossed, hundreds of parts hundreds, Fitter processing workload is too large, and inefficient (Car: to find each one is positive), the quality is not easy to guarantee, based on the above situation, comrade Tan Gengsheng comrades, the use of material system made a set of multi-purpose fixture shown in Figure 3:
