Under state, as shown in figure 5, clamp hand is in open configuration, hollow shaft drives clamp hand to make rotating motion, and clamp hand is under rotary motion state
Close to the copper wire of bending.
Example state 3:
After completing the step in example state 2, clamp hand opens the posture to make rotating motion close to carbon brush copper wire.Clamp hand arrives
Up to after copper wire root, motor stalls, feed motion terminates.At this point, 13 piston rod of cylinder is shunk, push rod connector 15 follows gas
Cylinder pushrod movement drives push rod to travel forward, so that the annulus 27 being connected with push rod travels forward, in clamp hand front end reset spring
Under the action of 29, closure is clamped copper wire root by clamp hand.
Example state 4:
After completing the step in example state 3, clamp hand has clamped copper wire root.At this point, motor does counter motion, lead screw
Motor is followed to do counter motion, all mechanisms on front end sliding block and rear end sliding block will be retreated along lead screw direction.At the same time,
Lead screw drives hollow shaft rotation by belt, and clamp hand will also follow hollow shaft to rotate.Clamp hand clips copper wire and makes rotating motion on one side,
It retreats on one side, until clamp hand leaves copper wire end, being straightened and afterturn (as shown in Figure 7) for copper wire is completed in motor stalling.
Being straightened with after afterturn for copper wire is completed, motor stalling, cylinder returns to original state.The rigidity of copper wire obtains
It improves, into next station, entire copper wire straightening device waits next carbon block copper wire to arrive.Carbon block in front process fixture into
Row clamps.
