我们在铣削过程中,常遇到单件、小批零件加工。往往为了加工一个键槽或一个平面,就得更换一套夹具,费时费力,工效低。为了大干快上,我们做了一个多用钳口(图1),其材料为45钢,热处理硬度HRC40～45。在单件小批生产时,将钳口的E、F两个基准面紧靠活动 We are in the process of milling, often encountered a single, small parts processing. Often in order to process a keyway or a plane, you have to change a set of fixtures, time-consuming and labor-intensive. In order to go faster, we made a multi-purpose jaws (Figure 1), the material is 45 steel, heat treatment hardness HRC40 ~ 45. In a single small batch production, the jaws E, F two datum close to the activities
