Gripper with a trident body section
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. The jaws rotate with respect to one another in response to fluid power in the cylindrical section. A pair of side plate members, each slide plate member has an elongated blind slot that receives an end of the cam assembly, the ends travel in the blind slot. Cam slots in the pair of opposing jaws, via a cam bushing.
