One prestressing force Jacquard sley point of the present invention, including piezoelectric vibrator, guide syringe needle, lower locating piece and upper locating piece,
It is characterized in that:
Piezoelectric vibrator includes elastic base plate and four piezoelectric ceramics；Described elastic base plate is sheet type structure, including centre
Cantilever, two side cantilevers and cantilever bonding pad, three cantilevers interact and play the effect that syringe needle skew is amplified；Described centre hangs
Arm includes that intermediate cantilever elongation zone and intermediate cantilever fixed area, one end, described intermediate cantilever elongation zone are arranged in described cantilever and connect
The side in district, the other end in described intermediate cantilever elongation zone is disposed with described intermediate cantilever fixed area, at described intermediate cantilever
It is disposed with on fixed area about hole, elastic base plate symmetrical axisymmetric two intermediate cantilever location, said two side size cantilever phase
Together and it is arranged symmetrically with about described elastic base plate axis of symmetry；Described piezoelectric ceramics is sheet type structure and is arranged in described side
The upper and lower surface of cantilever, produces syringe needle by inverse piezoelectric effect and offsets；Described intermediate cantilever and described side cantilever configuration are described
The same side of cantilever bonding pad, the opposite side in described cantilever bonding pad arranges guide syringe needle, for threading yarn；Described lower location
Block is made up of lower locating piece pedestal, two U-shaped boss and two positioning cylinders, and the upper surface at described lower locating piece pedestal is arranged
There are two equivalently-sized described U-shaped boss and are arranged symmetrically with about lower locating piece axis of symmetry, the open side of described U-shaped boss
It is arranged on leading flank formation side cantilever mounting groove；Side parallel with described leading flank on the cantilever mounting groove of described side is referred to as
Side cantilever locating surface, the lower surface of described side cantilever and the bottom surface of described side cantilever mounting groove connect to be arranged, side cantilever stretches out end
End face and described side cantilever locating surface connect to be arranged；Described lower locating piece pedestal upper surface also arrange two equivalently-sized and about
The symmetrical axisymmetric positioning cylinder of described lower locating piece, for positioning and voltage oscillator and upper locating piece, two described positioning cylinders
The spacing of axis place plane and described side cantilever locating surface is not equal to two described intermediate cantilever pilot hole axes place planes
With the spacing that described side cantilever stretches out terminal surface, therefore form prestressing force and predeformation；Hole, two location is had on upper locating piece,
This hole, location coordinates layout with the positioning cylinder of described lower locating piece.
After energising work, piezoelectric vibrator occurs cyclic bending to deform under the effect of alternating voltage, and piezoelectric vibrator drives and leads
Yarn syringe needle move, it is achieved the skew of whole sley point syringe needle, syringe needle drive yarn movement, the present invention relative to tradition sley point,
There is bigger side-play amount and power output, can effectively extend the service life of Jacquard sley point.
