Description
Technical field
The present invention relates to the slide cam selector of mechanical textile industry, be specifically related to a kind of piezoelectric ceramic needle selecting machine.More specifically, the present invention relates to a kind of piezoelectric ceramic needle selecting machine of replaceable piezoelectric ceramics driving piece.
Background technology
As everyone knows, in mechanical textile industry, according to technological requirement, control the method for operation of pin and can make style.At present, general way is to adopt slide cam selector, particularly piezoelectric ceramic needle selecting machine to realize the automatic operating of pin.As shown in figure 11, piezoelectric ceramic needle selecting machine 1000 comprises conductive base 10, a plurality of piezoelectric ceramics driving piece 30, is arranged on the needle selection head 20 of described a plurality of piezoelectric ceramics driving piece 30 front ends the structure of existing a kind of piezoelectric ceramic needle selecting machine.On described conductive base 10, with the fixedly wall 101 of one, fixedly wall 101 is with a plurality of pods 102 of coordinating with described piezoelectric ceramics driving piece 30 of being used for.In addition, on described fixedly wall 101 also with a plurality of translots 103.When making this piezoelectric ceramic needle selecting machine 1000, first prepare pedestal 10 and fixedly on wall 101, preparing corresponding translot 103 and pod 102, then piezoelectric ceramics driving piece 30 being put into pod 103 and guaranteed that piezoelectric ceramics driving piece 30 and two walls of pod 103 closely cooperate.Put into the piezoelectric ceramics driving piece 30 top of pod 103 lower than notch one desired depth of pod 102.Until described a plurality of piezoelectric ceramics driving pieces 30, all pack into after its corresponding a plurality of pod 102, thereby it is fixed by piezoelectric ceramics driving piece 30 with conducting resinl, after solidifying, to seal described translot 103.Needle selection head 20 can be fixedly connected with piezoelectric ceramics driving piece 30 before piezoelectric ceramics driving piece 30 packs into fixedly on wall 101.The driving power supply line 50 of piezoelectric ceramics driving piece 30 also can be welded in place as requested before piezoelectric ceramics driving piece 30 packs into fixedly on wall 101, after piezoelectric ceramics driving piece 30 fix in position, then by being connected with driving power (not shown) again after cable concentrator 40 arrangement boundlings.
There is following shortcoming in existing piezoelectric ceramic needle selecting machine: if one of them piezoelectric ceramics driving piece breaks down and can not work, because it is shut by conducting resinl, used a new piezoelectric ceramics driving piece to replace very difficult, or even impossible.Therefore,, even if this just causes a piezoelectric ceramics driving piece on piezoelectric ceramic needle selecting machine to break down and can not work, just whole piezoelectric ceramic needle selecting machine need to be replaced.And this piezoelectric ceramic needle selecting machine price is very expensive, change the increase that whole piezoelectric ceramic needle selecting machine certainly will cause equipment cost.
If the structure of piezoelectric ceramic needle selecting machine can make any piezoelectric ceramics driving piece wherein be changed easily, that will inevitably reduce the cost of use of piezoelectric ceramic needle selecting machine, thereby correspondingly reduces weaving production cost.
Summary of the invention
The object of the invention is to: a kind of novel piezo-electric ceramic slide cam selector is provided, overcome the above-mentioned defect that existing piezoelectric ceramic needle selecting machine exists, indivedual piezoelectric ceramics driving pieces on piezoelectric ceramic needle selecting machine can be convenient for changing when breaking down, thereby reduce production costs.
Technical scheme of the present invention is: a kind of piezoelectric ceramic needle selecting machine of replaceable piezoelectric ceramics driving piece, comprise a plurality of piezoelectric ceramics driving pieces and conductive base, it is characterized in that, the fastening structure that also comprises described piezoelectric ceramics driving piece, described fastening structure comprise be arranged on described conductive base vertical with described piezoelectric ceramics driving piece direction, Qie Qi two ends are threaded the guide rail in hole, intermediate plate in the middle of a plurality of, two outer intermediate plates and guide shaft, described a plurality of in the middle of in each of intermediate plates with the opening matching with described guide rail, both sides, Bing its underpart are used for accepting described guide shaft with at least two through holes, described outer intermediate plate in both sides, its underpart respectively with two through hole Bing bottoms accepting described guide shaft with the projection extending internally, in described projection with another through hole, when described piezoelectric ceramics driving piece being put between adjacent described intermediate plate, described in the middle of intermediate plate while being arranged in two through holes of described outer intermediate plate by described guide rail and guide shaft location and described guide shaft, another through hole by described outer intermediate plate of trip bolt and the screwed hole on described guide rail put in place described piezoelectric ceramics driving piece is fastening.
In a preferred specific embodiment, the drive electrode of described piezoelectric ceramics driving piece inserts in an electrode tip holder separably, described electrode tip holder comprises the drive electrode chamber that a plurality of and described piezoelectric ceramics driving piece matches, and the electrode that draw described drive electrode chamber is connected with driving power supply line.
More preferably, the electrode tip holder cover plate that described electrode tip holder removably connects with described electrode tip holder with one, on described electrode tip holder cover plate, be also removably connected with a fastening structure cover plate, when described fastening structure cover plate is in place, its front end compresses described piezoelectric ceramics driving piece.
In another preferred specific embodiment, the piezoelectric ceramic needle selecting machine of described replaceable piezoelectric ceramics driving piece also comprises the fastening structure cover plate being arranged on cable concentrator, described fastening structure cover plate and described cable concentrator removably connect and when being in place, the front end of described cover plate compresses described piezoelectric ceramics driving piece.
Preferably, for convenience of dismounting, between described adjacent middle intermediate plate and between described adjacent middle intermediate plate and outer intermediate plate, with spring, connecting.
The piezoelectric ceramic needle selecting machine of the replaceable piezoelectric ceramics driving piece in the present invention does not adopt conducting resinl or other resin material as the fixed sealing material of piezoelectric ceramic piece.When one of them piezoelectric ceramics driving piece breaks down cisco unity malfunction, can it be pulled down separately conductive substrates by unclamping fastening structure, then replace.Therefore, the piezoelectric ceramic needle selecting machine of this structure can conveniently be realized the replacing of single fault piezoelectric ceramics driving piece, and need when single piezoelectric ceramics driving piece breaks down, just to piezoelectric ceramic needle selecting machine, not carry out integral replacing, thereby reduces costs.
