The technical scheme that its technical problem that solves the utility model adopts is: lasting pincers is swept cutter platform electricity liquid adjusting device, comprise and sweep cutter platform casing and oil cylinder, sweep be provided with on the cutter table oil cylinder one the location nut, setscrew nut just becomes one with oil cylinder after fixing at cylinder bottom and cylinder cap place by two guide pads being attached thereto, the formation screw thread transmission that links to each other with screw shaft of this setscrew nut.
The two ends of described screw shaft are fixed on the casing by bearing, bearing holder (housing, cover), and an end of screw shaft has belt pulley to link by synchronous belt and motor.
Be provided with in the described oil cylinder and make piston and the piston rod move back and forth, this piston rod right-hand member is equipped with coupling block and is hinged on and sweeps on the supporting seat that cutter platform slide plate is fixed together by bearing pin.
The described cutter platform slide plate cunning of sweeping is contained on the guide rail of sweeping cutter platform casing top.
The beneficial effects of the utility model are: adopt sweeping and set up a location nut on the cutter table oil cylinder, this setscrew nut links to each other with screw shaft and constitutes the screw thread transmission, make that the anchor point of oil cylinder is adjustable, enlarged impulse stroke, had accurate positioning, adjust the precision height, time saving and energy saving, easy to operate, advantage that efficient is high.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of lasting pincers is swept cutter platform electricity liquid adjusting device, comprises and sweeps cutter platform casing and oil cylinder, and the right-hand member of screw shaft 7 is fixed on the right-hand member of casing by bearing 23, bearing seat 22; The middle part of screw shaft 7 and setscrew nut 8 constitute thread connection, and the semi-circular but mouth of guide pad 11 and 18 lower ends is placed on the smooth place, the left and right sides of screw shaft 7 threaded portions respectively; Screw shaft 7 can only rotate, and can not move axially; The right-hand member of screw shaft 7 is an input, and belt pulley 1 connects by the input of key 25 with screw shaft 7; Motor 6 links to each other with belt pulley 1 by main pulley 3, the synchronous belt 2 on reductor 5 and the output shaft.
Sweep the cylinder bottom 12 of cutter table oil cylinder, cylinder cap 17 connects firmly with guide pad 11 and 18 respectively, setscrew nut 8 is fixed in the middle of guide pad 11 and 18, the left end of screw shaft 7 is by bearing 9, bearing is sat 10 and is fixed, cylinder body 14 is packed in the centre of cylinder bottom 12 and cylinder cap 17 by bolt, piston rod 15 left ends and piston 13 are connected as one and can move back and forth in cylinder body 14, the right-hand member of piston rod 15 is equipped with coupling block 19 and is hinged on and sweeps on the supporting seat 21 that cutter platform slide plate 16 is fixed together by bearing pin 20, sweeps that cutter platform slide plate 16 is sliding to be contained on the guide rail of sweeping cutter platform casing 4 tops and pressing plate 24 formations.
When reality is used, when sweep cutter table oil cylinder through a hole entrance pressure power liquid to the A chamber, when liquid is returned through the b hole in the B chamber, cylinder body 14 is a fulcrum with setscrew nut 8, pressure liquid promotes piston 13 and moves to right in cylinder body 14 together with piston rod 15, the coupling block 19 of piston rod 15 by the end swept cutter platform slide plate 16 and moved right on guide rail with making with the hinged supporting seat 21 of bearing pin 20, when piston 13, when piston rod 15 is shifted to the right to the ultimate position in cylinder body 14, sweeping cutter platform slide plate 16 surges and adjust to finish, cut off oil circuit a sealing A chamber, this moment, motor 6 energisings were just changeed, by reductor 5, main pulley 3, synchronous belt 2, belt pulley 1 drives screw shaft 7 and clockwise rotates, make setscrew nut 8 drive cylinder body 14, cylinder bottom 12, cylinder cap 17 grades move right, under the effect of the liquid in the A chamber, piston 13, piston rod 15 also moves right, and the result is by coupling block 19, supporting seat 21 makes to be swept cutter platform slide plate 16 and continues to move right on guide rail, till reaching ideal position.
When sweep cutter table oil cylinder through b hole entrance pressure power liquid to chamber B, when liquid is returned through hole a in the A chamber, cylinder body 14 is a fulcrum with setscrew nut 8, pressure liquid promotes piston 13 and moves to left in cylinder body 14 together with piston rod 15, the coupling block 19 of piston rod 15 by the end swept cutter platform slide plate 16 and is moved to the left on guide rail with making with the hinged supporting seat 21 of bearing pin 20, when piston 13, when piston rod 15 moves left to the ultimate position in cylinder body 14, sweeping cutter platform slide plate 16 surges and adjust to finish, cut off oil circuit b sealing B chamber, motor 6 energising counter-rotatings this moment, by reductor 5, main pulley 3, synchronous belt 2, belt pulley 1 drives screw shaft 7 and rotates counterclockwise, setscrew nut 8 drives cylinder body 14, cylinder bottom 12, cylinder cap 17 grades move to left, under the effect of the liquid in the B chamber, piston 13, piston rod 15 also is moved to the left, the result is by coupling block 19, supporting seat 21 makes to be swept cutter platform slide plate 16 and continues to be moved to the left on guide rail, till reaching ideal position.
