Description
Technical field
The present invention relates to piezoelectric ceramics tricot machine technical field, more particularly to a kind of compound Jacquard sley point of multifunctional material.
Background technology
Jacquard sley point is used for jacquard warp, is the critical component for realizing jacquard weave function, the deflection of sley point is realized using inverse piezoelectric effect.Piezoelectric ceramic wafer by polarization can produce the deformation shunk and upheld plus voltage so that sley point offsets or offset to the right to the left.Have in existing Jacquard sley point using common rectangle piezoelectric vibrator, also have using prestressing force piezoelectric vibrator.Traditional prestressing force piezoelectric vibrator has the advantages of service life is long, required voltage is low, output displacement is big, it is necessary to first apply prestressing force in the pre-assembly, in actual use, applies stressing operations complexity, and process needs very high precision.
The content of the invention
Apply stressing operations complexity to solve traditional prestressing force Jacquard sley point, and process needs the problem of very high precision, propose a kind of compound Jacquard sley point of multifunctional material, piezoelectric vibrator in the sley point applies prestressing force using memorial alloy, it is simple to operate, prestressing force can be applied on demand, improve the life-span of prestressing force Jacquard sley point.
To achieve these goals, the present invention uses following technical scheme：
A kind of compound Jacquard sley point of multifunctional material of the present invention, including piezoelectric vibrator, electric heating piece and guide syringe needle, it is characterised in that：
Piezoelectric vibrator includes elastic base plate and two panels piezoelectric ceramics, the elastic base plate includes two side cantilevers, intermediate cantilever, flexure mems alloy, positioning area and syringe needle bonding pad, two side cantilevers are arranged symmetrically on intermediate cantilever, the flexure mems alloy is to be converted into trapezoidal thin-slab structure along its length, bending folding line is vertical with length direction, and the flexure mems alloy is connected between the positioning area and the intermediate cantilever；Two panels electric heating piece is arranged on the flexure mems alloy surface；Piezoelectric ceramics described in two panels is arranged in two side cantilever surfaces；Guide syringe needle is arranged in one end of the syringe needle bonding pad.
It is vertical with length direction to bend folding line to be converted into trapezoidal thin-slab structure along its length or being converted into along its length on the symmetrical polygon thin-slab structure of plane where the cantilever of side for the flexure mems alloy.
During work, it is powered to electric heating piece, electric heating piece is begun to warm up to memorial alloy, and when the set temperature is reached, memorial alloy shrinks deformation, tenses intermediate cantilever, and intermediate cantilever is applied with prestressing force.After applying drive signal on piezoelectric vibrator, cyclic bending deformation occurs in the presence of alternating voltage for piezoelectric vibrator, and piezoelectric vibrator drives the motion of guide syringe needle, realizes the skew of whole sley point syringe needle, and syringe needle drives yarn movement.After being stopped, electric heating piece stops heating, and memorial alloy restores to the original state, and prestressing force disappears.It is of the invention compared with common prestressing force Jacquard sley point, the present invention in piezoelectric vibrator using memorial alloy apply prestressing force, it is simple to operate, prestressing force can be applied on demand, improve the life-span of prestressing force Jacquard sley point.
