Operation principle：
This clamp system, can fix 4 workpiece simultaneously, and during clamping, 4 workpiece are respectively put into the first station 71, the second work
Position 72, the station 74 of 3rd station 73 and the 4th, then tightening nuts 31, when unclamping workpiece, only need to unscrew nut 31, this
Clamp system uses manual locking, easy to operate, securely and reliably.
During fixed workpiece, with screwing for nut 31, the first pressing plate 21 by nut 31 thrust to right translation, so as to press from both sides
Workpiece on tight first station 71；Meanwhile as the precession to the right of nut 31, screw rod 3 are moved to the left by reaction force, from
And the second pressing plate 22 is driven to move to left and clamp the workpiece in second station 72；Second pressing plate 22 is moved to left, and linkage board 5 will be driven left
Move, and then drive the lower end of the 3rd pressing plate 23 to left movement, because the middle part of the 3rd pressing plate 23 is left with being fixed on second boss 12
The first support bar 61 of side is hinged, and its lower end rotates pin joint of the 3rd pressing plate 23 around middle part, the 3rd pressing plate to left movement
23 top will move right, so as to clamp the workpiece on the station of 3rd station 73；And moving to right for the first pressing plate 21, pass through push rod
The lower end of 4 the 4th pressing plates 24 of drive moves right, due to the 4th pressing plate 24 middle part and be fixed on the of the right side of second boss 12
Two support bars 62 are hinged, and its lower end moves right, make the 4th pressing plate 24 around middle part pin joint rotate, the 4th pressing plate 24 it is upper
Portion will be moved to the left, so as to clamp the workpiece on the station of the 4th station 74；Pressed from both sides while so just realizing workpiece on 4 stations
Tightly.
When unclamping workpiece, make counter motion, as nut 31 exits to the left, lose the thrust of nut 31, each pressure
Plate departs from the workpiece on corresponding station naturally；And acted in the elastic force of the first spring 3a, second spring 3b and back-moving spring 8
Under, automatically reseting for each pressing plate is realized, workpiece is easily removed.
Highly preferred embodiment of the present invention has illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
It can depart from the scope of the present invention.
