Abstract
An apparatus and method for fusing terminal or commutator wire connections on an armature or stator, including an electrode, a pneumatic locking cylinder for driving the electrode into contact with the workpiece and applying a force to the workpiece, a load cell for measuring the force applied by the electrode, an opposition cylinder for providing an opposition force to the electrode after a cold-forming force has been reached by the electrode, a linear potentiometer for measuring the distance traveled by the electrode after the opposition force has been applied; and a locking mechanism for stopping the locking cylinder after a predetermined distance has been traveled during the weld cycle.
Claims15
An apparatus for fusing a workpiece consisting of at least two electrically conductive elements comprising:
- an electrode;
- means for moving the electrode into contact with said workpiece causing said electrode to apply a force to said workpiece;
- means for monitoring the force applied by said electrode;
- and
- means for applying an opposition force to said electrode when a predetermined force has been reached by said electrode to relieve a portion of said force applied by said electrode to said workpiece.
A method for fusing a workpiece including at least two electrically conductive elements comprising the steps of:
- moving an electrode into contact with said workpiece;
- applying a force to said workpiece;
- monitoring said applied force until a predetermined force is reached;
- initiating a weld cycle;
- applying an opposition force to said workpiece to relieve a portion of said force;
- measuring electrode distance travel after said opposition force is applied;
- and
- stopping said electrode after a predetermined distance has been traveled by said electrode.
