  • Patent number: 10994423
    Abstract: A modular gripper has a body with a trident section and cylindrical section. A powering assembly is positioned in the cylindrical section. A pair of oppositing jaws is pivotally secured between a center wall and a pair of side wall, respectively, of the trident section. The clevis cam driver with piston rod moves a cam assembly on the centre wall slot. The cam assembly passes through a body having a trident section and cylindrical section. The trident section comprises a trident structure that includes, at one end, a pair of side walls along with a center wall. The cylindrical section includes a fluid driven powering assembly. A pair of opposing jaw member are pivotally secured to the trident portion about separate pivot pins. A cam assembly is operatively connected to a piston rod of the fluid driven powering assembly. The cam assembly extends laterally outward with respect to a cylinder bore axis to receive a cam bush that engages with a through slot on each of the pair of opposing jaw members.

  • Patent number: 9908219
    Abstract: A clamp apparatus includes a pair of first and second clamp arms. A driving force transmission mechanism transmits a driving force of a drive unit, whereby the first clamp arm is operated to rotate via a link arm, while simultaneously, the second clamp arm is rotated, and after being rotated through a predetermined angle, under moving action of a roller, which is inserted into a cam groove of a link plate, rotation of the second clamp arm is stopped and maintained in advance with respect to the first clamp arm. Consequently, after positioning of a workpiece has been carried out by the second clamp arm, rotation of which is stopped, the first clamp arm continues to be rotated, whereby the workpiece is clamped.

  • Patent number: 9486585
    Abstract: A drive ram for use with a medical fluid injector may include a central, longitudinal reference axis. First and second gripper members may be pivotally interconnected with a plunger engaging end of the drive ram. Each of the first and second gripper members may be pivotable about a common pivot axis that intersects the reference axis. Each of the gripper members may further include a first end that is remote from the common pivot axis. In some embodiments, the first and second gripper members may be pivotable between a first position and a second position. In the first position, the first ends of the gripper members may be spaced apart by a first distance, while in the second position, they may be spaced apart by a second distance that is greater than the first distance.
