在生产中,为了适应不同尺寸工件的装夹需要,我们往往要更换不同规格的虎钳,而频繁地装卸虎钳势必会影响工件的装夹速度,浪费工时。于是,我们在所有虎钳上都安上了一种新式夹爪。这种夹爪是由两对夹爪组成(分别叫做内夹爪和外夹爪)。这两对夹爪上面都钻有直径为0.25in的螺孔,以便和两个档块相连(见图)。其中,外夹爪做得比内夹爪要高,这样在装夹尺寸较大的工件时,可不必
In production, in order to adapt to different sizes of workpiece clamping needs, we often have to replace the different specifications of the vise, and frequent loading and unloading vices is bound to affect the clamping speed of the workpiece, a waste of man-hours. So, we put a new type of jaw on all the vices. The jaws are made up of two pairs of jaws (inner jaw and outer jaw, respectively). Both pairs of jaws are drilled with a 0.25in diameter screw hole to connect with the two stops (see picture). Among them, the outer jaw is done higher than the jaws, so when clamping the larger size of the workpiece, you do not have to
