机用平口钳在夹紧长方形工件或圆形工件时,常常因夹紧使工件向上拱起,须反复敲打,不使工件拱起,这样不但增加了辅助时间,也容易影响加工质量。为此我们改制成如图所示平口钳钳口。在机用平口钳钳口上加工出一个α角度,为了避免自锁的影响,α可取在20°～25°之间,我们取了α角等于20°,左右两个钳口铁,各用两个内六角螺钉安装在钳体上,钳口铁1
Mechanical clamping pliers in the clamping rectangular workpiece or circular workpiece, often because of clamping the workpiece arch upward, repeated beating, not to arching the workpiece, this will not only increase the auxiliary time, but also easily affect the processing quality. To this end, we reformed into a flat-nose pliers as shown. In the machine mouth jaw pliers processing an α angle, in order to avoid the impact of self-locking, α desirable between 20 ° ~ 25 °, we take α angle is equal to 20 °, left and right two jaw iron, each with two A hexagonal screw mounted on the caliper body, jaw iron 1
