Abstract
The utility model relates to a needle selector used in mechanical textile industry, in particular relates to a piezoceramic needle selector. The piezoceramic needle selector does not select resin materials as solid seal materials of piezoceramic patches. When one piezoceramic patch is failed and cannot work normally, a cover plate can be removed firstly, and then inverted U-shaped conductive elastic material can be taken out, and then the failed piezoceramic patch can be taken out. A new piezoceramic patch is installed in a vertical slot, and then the inverted U-shaped conductive elastic material is inserted in a cross slot so as to match with the piezoceramic patch in place, and finally the cover place is fixed on a base so as to tightly press the inverted U-shaped conductive elastic material. Thus, the piezoceramic needle selector with the structure provided by the utility model can conveniently realize replacement of single failed piezoceramic patch, and overall replacement of the piezoceramic needle selector is not required when single piezoceramic patch is failed, thereby reducing the use cost.
Description
Technical field
The present invention relates to the needle selection device 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 ceramic piece.
Background technology
As everyone knows, in mechanical textile industry, according to technological requirement, the method for operation of control pin can be made style.At present, general way is to adopt needle selection device, particularly piezoelectric ceramic needle selecting machine to realize the automatic operating of pin.The structure of existing a kind of piezoelectric ceramic needle selecting machine is as shown in Figure 1, and piezoelectric ceramic needle selecting machine 100 comprises conductive base 10, a plurality of piezoelectric ceramic piece 20, is installed in the needle selection head of said a plurality of piezoelectric ceramic piece 20 front ends.The fixing wall 101 that has one on the said conductive base 10, fixing wall 101 have a plurality of pods 102 of cooperating with said piezoelectric ceramic piece 20 of being used for.In addition, on said fixing wall 101, also have a plurality of translots 103.When making this piezoelectric ceramic needle selecting machine 100; At first prepare pedestal 10 and on fixing wall 101, prepare corresponding translot 103 and pod 102, then piezoelectric ceramic piece 20 is put into pod 103 and guarantee that piezoelectric ceramic piece 20 and two walls of pod 103 closely cooperate.The top of having put into the piezoelectric ceramic piece 20 of pod 103 is lower than notch one desired depth of pod 103.Treat that described a plurality of piezoelectric ceramic piece 20 all packs into behind its corresponding a plurality of pod 103, use insulating cement, thereby it is fixed with piezoelectric ceramic piece 20 after solidifying, to seal described translot 102 like epoxide-resin glue.Needle selection head 30 can be fixedly connected with piezoelectric ceramic piece 20 on piezoelectric ceramic piece 20 is packed fixing wall 101 into before.The driving power supply line 50 of piezoelectric ceramic piece 20 also can be welded in place on piezoelectric ceramic piece 20 is packed fixing wall 101 into before as requested; After treating piezoelectric ceramic piece 20 fix in position, then through being connected with the driving power (not shown) again behind the cable concentrator 40 arrangement boundlings.
There is drawback in existing piezoelectric ceramic needle selecting machine: if one of them piezoelectric ceramic piece breaks down and can not work,, it is more changed very difficulty with a new piezoelectric ceramic piece because it is shut by epoxide-resin glue, or even impossible.Therefore, even this just causes a piezoelectric ceramic piece on the piezoelectric ceramic needle selecting machine to break down and can not work, just need whole piezoelectric ceramic needle selecting machine is more changed.And this piezoelectric ceramic needle selecting machine price is very expensive, changes 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 ceramic piece wherein changed easily, that will inevitably reduce the cost of use of piezoelectric ceramic needle selecting machine, thereby reduces production costs.
Summary of the invention
The objective of the invention is to: a kind of novel piezo-electric ceramic needle selection device is provided; Overcome the above-mentioned defective that existing piezoelectric ceramic needle selecting machine exists; Indivedual piezoelectric ceramic pieces on the piezoelectric ceramic needle selecting machine can be convenient for changing when breaking down, thereby reduce production costs.
The length direction of " indulging " of the present invention, " vertically " finger pressure electroceramics sheet; The thickness direction of " horizontal stroke ", " laterally " finger pressure electroceramics sheet, this direction is vertical with the length direction of piezoelectric ceramic piece.
The piezoelectric ceramic needle selecting machine of the replaceable piezoelectric ceramic piece among the present invention comprise pedestal, with the fixing wall and the piezoelectric ceramic piece of pedestal one; Said fixing wall is provided with and the consistent pod of said piezoelectric ceramic piece length direction; Said piezoelectric ceramic piece is positioned in the said pod and closely cooperates with two walls of pod; It is characterized in that, also be provided with two translots in each pod both sides on the said fixing wall, and said translot length in the vertical is less than said fixing wall length in the vertical; Two limits of one inverted U-shaped conductive elastomer U cooperate and on each limit, all have convexity with said two translots; Make when said inverted U-shaped conductive elastomer is in place; Said convexity tightly props up the two sides of said piezoelectric ceramic piece; And the top downside of inverted U-shaped conductive elastomer props up the upside of piezoelectric ceramic piece, and the top upside of inverted U-shaped conductive elastomer then exceeds the upper surface of said fixing wall a little; On said pedestal, also be fixed with a cover plate, said cover plate compresses the top of described inverted U-shaped conductive elastomer when being in place.
In a specific embodiment, said inverted U-shaped conductive elastomer is made of copper.
In a specific embodiment, said cover plate is fixed on the said pedestal through screw.
In a further embodiment, said cover plate adopts engineering plastics to process.
The piezoelectric ceramic needle selecting machine of the replaceable piezoelectric ceramic piece among the present invention does not adopt the fixed sealing material of resin material as piezoelectric ceramic piece.When one of them piezoelectric ceramic piece breaks down cisco unity malfunction, can at first remove cover plate, take out inverted U-shaped conductive elastomer then, take out the fault piezoelectric ceramic piece again.With the new piezoelectric ceramic piece pod of packing into, then inverted U-shaped conductive elastomer is inserted translot and make it to cooperate and put in place with piezoelectric ceramic piece, cover plate is fixed to makes it to compress inverted U-shaped conductive elastomer on the pedestal at last.Therefore, the piezoelectric ceramic needle selecting machine of this structure can conveniently be realized the replacing of single fault piezoelectric ceramic piece, and does not need when single piezoelectric ceramic piece breaks down, and just piezoelectric ceramic needle selecting machine is carried out integral replacing, thereby reduces cost.
