摘要： The invention concerns an adjustable precision grinding and machinist vise which has a novel mechanism for precisely clamping metal pieces, tools, and other articles between a movable jaw and a stationary jaw. The vise is made such that it can be mounted on larger machines such as lathes, drills, milling machines, surface grinders and the like. The device employs a series of notches in the base as a guide means to stabilize clamping. A pin engages, at its lower end, a guide with opposite flanges which guide also has a central wedge with an arcuate load bearing surface. The pin extends through a rotatable clamp disposed within an angling shoulder on the movable jaw. The pin is disposed through the movable jaw and into a chamber in the base for engagement in the guide means to thereby insure precise positioning. Threadably tightening the pin into the guide snugs either the arcuate upper surface of the wedge or the arcuate upper surface of the flanges, or both into engagement with an upper surface of the chamber in the base. The rotatable clamp and wedge (as well as flanges) allow rotation such that the movable jaw moves toward the stationary jaw of the vise upon tightening.

摘要翻译： 本发明涉及一种可调节的精密研磨和机械虎钳，其具有用于在活动夹爪和固定夹爪之间精确夹紧金属片，工具和其它制品的新颖机构。 台钳制造成可以安装在诸如车床，钻头，铣床，平面磨床等较大的机器上。 该装置在基座中采用一系列切口作为引导装置，以稳定夹紧。 销在其下端处接合具有相对凸缘的引导件，该引导件还具有具有弓形承载表面的中心楔形件。 销延伸穿过设置在可动夹爪上的倾斜肩部内的可旋转夹具。 销穿过可动夹爪并进入基座中的腔室中以与导向装置接合，从而确保精确定位。 将销螺纹拧紧到引导件中，可以将楔形件的弧形上表面或法兰的弓形上表面紧贴，或者两者都与底座中的腔室的上表面接合。 可旋转的夹具和楔形件（以及法兰）允许旋转，使得当紧固时可动夹爪朝向虎钳的固定夹爪移动。
