Description
Technical field
The invention belongs to piezoelectric ceramics tricot machine technical field, and in particular to a kind of adjustable piezoelectric vibrator slide cam selector of prestressing force.
Background technology
In mechanical textile industry, slide cam selector is the accuracy and reliability that needle selection control will be all directly affected for implementing the key element, its properity etc. of needle selection control.Conventional piezoelectric formula slide cam selector makes piezoelectric element bend to the shape remembered in advance to carry out needle selection using inverse piezoelectric effect, with fast response time, heating less, power consumption is small the characteristics of, but it goes out that needle force degree is inadequate, and displacement output ability is low, easily cause style sewing quality poor.Amplitude and power output can be increased by using prestressing force piezoelectricity slide cam selector and effectively improving out needle force degree increases output displacement, but its technological difficulties is to need to be previously applied prestressing force in the pre-assembly, during practical set, apply stressing operations complexity, and operating process precision prescribed is high.
The content of the invention
It is small in order to solve current conventional piezoelectric slide cam selector output displacement, and prestressing force piezoelectricity slide cam selector applies stressing operations complexity, and process required precision it is high the problem of, propose a kind of adjustable piezoelectric vibrator slide cam selector of prestressing force, elastic base plate in the adjustable piezoelectric vibrator slide cam selector of the prestressing force is disposed with bent plate pretension arm, DC voltage is applied by the pretension piezoelectric ceramics posted to surface and produces pretightning force, compared to conventional prestressing force piezoelectricity slide cam selector, it is simple that the present invention applies stressing operations, and prestressing force can be applied on demand, with easy assembling, prestressing force is adjustable, output displacement is big, the advantages that service life is long.
To achieve these goals, the present invention uses following technical scheme：
A kind of adjustable piezoelectric vibrator slide cam selector of prestressing force of the present invention, including piezoelectric vibrator, cutter head connecting pin, middle circle pin, top dowel pin and pretension piezoelectric ceramics, wherein：
The piezoelectric vibrator is made up of elastic base plate and four piezoelectric ceramics；The elastic base plate includes two side cantilevers, intermediate cantilever and cantilever bonding pad；Described two side cantilevers are arranged symmetrically on intermediate cantilever；Described two side cantilever and intermediate cantilever homonymy one end are arranged on the top dowel pin；The upper and lower surface of described two side cantilevers is respectively arranged the piezoelectric ceramics of sheet type structure；The intermediate cantilever is disposed with bent plate pretension arm close to one end of top dowel pin；The bent plate pretension arm is the thin-slab structure for being converted into V-arrangement along its length, is made up of two rectangular surfaces mutually to form an angle, bent plate folding line is vertical with length direction；Pretension piezoelectric ceramics is pasted with two rectangular surfaces of the bent plate pretension arm, apply DC voltage makes bent plate pretension arm bend by inverse piezoelectric effect, and then produces prestressing force；Described two side cantilevers and intermediate cantilever are arranged in the same side of the cantilever bonding pad；The cutter head connecting pin is arranged in the opposite side of the cantilever bonding pad；The middle circle pin is arranged on the cantilever bonding pad close to the side of two side cantilevers.
During work, apply DC voltage to pretension piezoelectric ceramics, bent plate pretension arm stress occurs bending and deformation, and tenses intermediate cantilever, and now the two of piezoelectric vibrator side cantilever is applied in upper prestressing force by the pulling force of intermediate cantilever.After applying alternating current drive signal on piezoelectric vibrator, cyclic bending deformation occurs in the presence of alternating voltage for piezoelectric vibrator, and piezoelectric vibrator drives slide cam selector output displacement, realizes the adjustable selective mechanization operation for going out pin, completing pin, realizes the sewing of style.After being stopped, pretension piezoelectric ceramics is stopped power supply, and bent plate pretension arm restores to the original state, and prestressing force disappears.Compared with conventional prestressing force piezoelectricity slide cam selector, the piezoelectric vibrator in the present invention applies prestressing force using pretension piezoelectric ceramics, simple to operate, can apply prestressing force on demand, has the advantages that easily assembling, prestressing force is adjustable, output displacement is big, service life is long.
