    Abstract: A latch blocks the opening of workpiece clamping arms in a machine tool, such as a crankpin grinding machine, until the crank fixtures are precisely angularly located. As the latch releases the clamping arms, a plunger is urged into an aperture in each crankhead positively locking the crank fixtures to the crankhead in the proper angular position for loading and unloading workpieces. Movement of the plunger into the crankhead closes a switch completing a circuit to open the clamping arms.

    Abstract translation: 闩锁将工件夹紧臂的开口阻塞在诸如曲柄销磨床的机床中,直到曲柄夹具精确地定位。 当闩锁释放夹紧臂时,柱塞被推动到每个曲柄头中的孔中,将曲柄固定装置正确地锁定到曲柄头处于适当的角度位置,用于装载和卸载工件。 柱塞进入曲柄头的运动关闭一个完成电路以打开夹紧臂的开关。
