    • An apparatus for gripping objects comprising a first jaw having a first support member and a first support plate that is slidingly attached to the support member with respect to a first direction or motion. The apparatus is also comprised of a second jaw that has a second support member and a second surface plate attached to the second surface member. Additionally, the apparatus is comprised of a structure holding the first jaw and the second jaw such that the first jaw and the second jaw can move in a second direction toward or away from each other to grip or release the object, respectively. In a preferred embodiment, the second surface plate is fixedly attached to the second support member and the first direction is perpendicular to the second direction. The sliding action of the first support plate acts to reduce the effective frictional force between the object and jaws to facilitate stable grasping.
    • 一种用于夹持物体的装置,包括具有第一支撑构件和相对于第一方向或运动滑动地附接到支撑构件的第一支撑板的第一钳口。 该装置还包括具有第二支撑构件和附接到第二表面构件的第二表面板的第二钳口。 此外,该装置由保持第一钳口和第二钳口的结构构成,使得第一钳口和第二钳口可以分别沿着第二方向或彼此远离彼此移动以夹持或释放物体。 在优选实施例中,第二表面板固定地附接到第二支撑构件,并且第一方向垂直于第二方向。 第一支撑板的滑动作用用于减小物体和夹爪之间的有效摩擦力,以便于抓握。

    • A fixture process and method is provided for developing a complete set of all admissible fixture designs for a workpiece which prevents the workpiece from translating or rotating. The fixture processor generates the set of all admissible designs based on geometric access constraints and expected applied forces on the workpiece. For instance, the fixture processor may generate a set of admissible fixture designs for first, second and third locators placed in an array of holes on a fixture plate and a translating clamp attached to the fixture plate for contacting the workpiece. In another instance, a fixture vice is used in which first, second, third and fourth locators are used and first and second fixture jaws are tightened to secure the workpiece. The fixture process also ranks the set of admissible fixture designs according to a predetermined quality metric so that the optimal fixture design for the desired purpose may be identified from the set of all admissible fixture designs.
    • 提供了一种固定工艺和方法,用于开发用于工件的一整套允许的夹具设计,防止工件平移或旋转。 夹具处理器基于几何访问约束和对工件的预期施加力产生所有允许设计的集合。 例如,固定装置处理器可以产生一组可容许的夹具设计,用于放置在固定板上的孔阵列中的第一,第二和第三定位器以及附接到固定板的用于接触工件的平移夹具。 在另一种情况下,使用夹具,其中使用第一,第二,第三和第四定位器,并且紧固第一和第二固定夹爪以固定工件。 固定过程还根据预定的质量度量对一组允许的夹具设计进行排列,从而可以从所有允许的夹具设计的集合中识别用于期望目的的最佳夹具设计。
