    • A workpiece holding assembly includes a base member which has a first support portion extending therefrom at a first position, a second support portion extending therefrom at a second position, a third support portion extending therefrom at a third position, and a fourth support portion extending therefrom at a fourth position. A first workpiece engaging member extends between the first support portion and the second support portion and is adapted for at least partial rotational movement. A second workpiece engaging member extends between the third support portion and the fourth support portion and is adapted for at least partial rotational movement. Each workpiece engaging member may include an outer surface having at least one substantially planar surface portion and at least one curved surface portion. The second workpiece engaging member may run substantially parallel to the first workpiece engaging member. Pairs or other multiples of such holding assemblies may be utilized for engaging and holding a rokpiece.
    • 工件保持组件包括基部构件,其具有在第一位置处从其延伸的第一支撑部分,在第二位置从其延伸的第二支撑部分,在第三位置从其延伸的第三支撑部分和从其延伸的第四支撑部分 在第四个位置。 第一工件接合构件在第一支撑部分和第二支撑部分之间延伸并且适于至少部分旋转运动。 第二工件接合构件在第三支撑部分和第四支撑部分之间延伸并且适于至少部分旋转运动。 每个工件接合构件可以包括具有至少一个基本平坦的表面部分和至少一个弯曲表面部分的外表面。 第二工件接合构件可以基本上平行于第一工件接合构件延伸。 这种保持组件的对或其他倍数可以用于接合和保持罗克。

    • A clamping apparatus includes two pairs of rotatable and substantially cylindrical clamping elements positioned on jaws of the clamping apparatus. One pair of clamping elements is located on a fixed jaw, and the second pair is located on a movable vise jaw. The jaws are supported on a generally rectangular base which has a pair of end portions. One end portion is a first upstanding flange formed integrally with the base. The second end portion is the fixed jaw. A two-way threaded rod is carried by the movable vise jaw and one threaded end extends through a cooperating threaded recess in the first upstanding flange. The movable vise jaw has a transverse notch located in its bottom to receive a hollow cylindrical nut which is internally threaded in a first direction. Adjacent to the cylindrical nut is a friction ring. The second threaded end of the threaded rod, threaded in the second direction, is threaded into the cylindrical nut. There are two speeds for moving the movable vise member towards the fixed member. One speed of movement occurs when the clamping members are not in engagement with the workpiece. The second speed of movement occurs when the clamping members are engaging the workpiece.
    • 夹紧装置包括定位在夹紧装置的夹爪上的两对可旋转且基本上圆柱形的夹紧元件。 一对夹紧元件位于固定夹爪上,第二对位于可动虎钳上。 夹爪支撑在具有一对端部的大致矩形的基部上。 一个端部是与底座一体形成的第一直立凸缘。 第二端部是固定爪。 双向螺纹杆由可动虎钳夹持,一个螺纹端延伸穿过第一直立法兰中的配合螺纹凹槽。 可动虎钳具有位于其底部的横向凹口,以容纳在第一方向上内螺纹的中空圆柱形螺母。 与圆柱形螺母相邻的是一个摩擦环。 螺纹杆的第二螺纹端在第二方向上螺纹拧入圆柱形螺母。 有两个速度可移动虎钳部件朝向固定部件移动。 当夹紧构件不与工件接合时,发生一个移动速度。 当夹紧构件接合工件时,发生第二速度移动。

    • A material-saving and energy-saving multifunctional bench clamp includes a movable clamp body, a fixed clamp body and a transmission pair of a screw and a nut. The fixed clamp body is provided with a holding accessory and a retractable locating-guiding device. The movable clamp body is made up of a left part and a right part. The left part is provided with two work heads, each head includes holding members, which form a holding assembly together with the accessories installed on the fixed clamp body. At least two axially locating-guiding key grooves are shaped on the cylinder guide rail of the right part and positioned the corresponding work heads of the left part. The bench clamp not only reduces processing surfaces and costs, but also saves about 30% material of clamper body under the same standard size and rated clamp force by comparison to the old multifunctional bench clamp.
    • 一种省电节能多功能台架夹具包括一个可动的夹具体,一个固定的夹具体和一个螺钉和一个螺母的传动对。 固定夹具体设置有保持附件和伸缩定位引导装置。 可动夹具主体由左部和右部构成。 左部设有两个工作头,每个头包括保持构件,其与安装在固定夹具体上的附件一起形成保持组件。 至少两个轴向定位导向键槽在右侧部分的气缸导轨上成形,并将左侧部分的相应工作头定位。 台式夹具不仅减少了加工表面和成本,而且与旧的多功能工作台夹相比,可以节省大约30%的相同标准尺寸的夹具主体材料和额定夹紧力。
