Family of pliers for clamping plates having similar and preferably identical frames, and pliers from such family

摘要

The invention relates to pliers for clamping plates used in conjunction with a manipulator arm, comprising a rigid frame connected to a carrier such as a rigid stand or robot, and an articulation sub-assembly connected to the frame and comprising a fixed arm, a mobile arm, and a main actuator for displacing the mobile arm in translation or rotation relative to the fixed arm for closing or opening the pliers and respectively clamping the plate assembly between the arms or releasing said assembly, wherein said pliers belong to a family of pliers comprising C- and X-shaped pliers, the frame having a similar shape and appearance for all the pliers of said family. Application mainly in the family of C- and X-shaped resistance-welding pliers having similar and preferably identical frames.

主权项

1. A rigid frame having a lateral flank defining one side thereof, wherein the lateral flank is configured to alternately support a first subassembly and a second subassembly, wherein each subassembly can be interchangeably mounted to the lateral flank, wherein the first subassembly includes at least one clamp associated with C-type kinematics, and the second subassembly includes at least one clamp associated with X-type kinematics, the rigid frame comprising:
at least one orifice configured to support a pivot pin in the orifice about which a rigid lever and attached mobile arm can be pivoted with respect to the clamp associated with X-type kinematics; wherein the lateral flank is configured to support the clamp associated with C-type kinematics as a linearly translatable subassembly; and wherein the opposite side of said frame is configured to be connected to an associated support element; wherein each respective interchangeable clamp defines a movable subassembly having components that include: a first stationary arm, a second mobile arm, and a main actuator configured to bear against the lateral flank supporting said stationary arm and capable of moving said mobile arm with respect to said stationary arm according to a first degree of freedom, regardless of whether in translation or rotation, so as to close or open the respective clamp, wherein all components of each respective movable subassembly are directly mountable only to the one lateral flank side of the frame.
