Abstract
The invention relates to needle selecting machines in the mechanical textile industry, in particular to a piezoelectric ceramic needle selecting machine. According to the piezoelectric ceramic needle selecting machine, resin materials do not serve as sealing materials of replaceable piezoelectric ceramic plates. When one piezoelectric ceramic plate fails and cannot normally work, a cover plate can be removed at first, an inverted U-shaped conductive elastic material is taken out, and the failed piezoelectric ceramic plate is taken out; a new piezoelectric ceramic plate is arranged in a longitudinal groove, and the inverted U-shaped conductive elastic material is inserted into a transverse groove to match the piezoelectric ceramic plate in place; and the cover plate is fixed to a base to press the inverted U-shaped conductive elastic material finally. Therefore, by the piezoelectric ceramic needle selecting machine with the structure, a single failed piezoelectric ceramic plate can be convenient to replace, while the piezoelectric ceramic needle selecting machine is not needed to be wholly replaced when the single piezoelectric ceramic plate fails; and therefore, the using cost is reduced.
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 ceramic 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 1, piezoelectric ceramic needle selecting machine 100 comprises conductive base 10, a plurality of piezoelectric ceramic piece 20, is arranged on the needle selection head of described a plurality of piezoelectric ceramic piece 20 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 ceramic piece 20 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 100, first prepare pedestal 10 and fixedly on wall 101, preparing corresponding translot 103 and pod 102, then piezoelectric ceramic piece 20 being put into pod 103 and guaranteed that piezoelectric ceramic piece 20 and two walls of pod 103 closely cooperate.Put into the piezoelectric ceramic piece 20 top of pod 103 lower than notch one desired depth of pod 103.Until described a plurality of piezoelectric ceramic pieces 20, all pack into after its corresponding a plurality of pod 103, with insulating cement, thus as piezoelectric ceramic piece 20 is fixed in the translot 102 of epoxide-resin glue as described in sealing after curing.Needle selection head 30 can be fixedly connected with piezoelectric ceramic piece 20 before piezoelectric ceramic piece 20 packs into fixedly on wall 101.The driving power supply line 50 of piezoelectric ceramic piece 20 also can be welded in place as requested before piezoelectric ceramic piece 20 packs into fixedly on wall 101, after piezoelectric ceramic piece 20 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 ceramic piece breaks down and can not work, because it is shut by epoxide-resin glue, used a new piezoelectric ceramic piece to replace very difficult, or even impossible.Therefore,, even if this just causes a piezoelectric ceramic 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 ceramic piece wherein be 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 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 ceramic pieces on piezoelectric ceramic needle selecting machine can be convenient for changing when breaking down, thereby reduce production costs.
" indulging " of the present invention, " longitudinally " refer to the length direction of piezoelectric ceramic piece; " horizontal stroke ", " laterally " refer to the thickness direction of piezoelectric ceramic piece, and this direction is vertical with the length direction of piezoelectric ceramic piece.
The piezoelectric ceramic needle selecting machine of the replaceable piezoelectric ceramic piece in the present invention comprise pedestal, with fixedly wall and the piezoelectric ceramic piece of pedestal one, described fixedly wall is provided with the pod consistent with described piezoelectric ceramic piece length direction, described piezoelectric ceramic piece is positioned in described pod and with two walls of pod and closely cooperates, it is characterized in that, on described fixedly wall, in each pod both sides, be also provided with two translots, and described translot length is in the vertical less than described fixedly wall length in the vertical; The Liang Ge limit of one inverted U-shaped conductive elastomer U coordinate with described two translots and on each limit with projection, when described inverted U-shaped conductive elastomer is in place, described projection tightly props up the two sides of described piezoelectric ceramic piece, and the top downside of inverted U-shaped conductive elastomer props up the upside of piezoelectric ceramic piece, the top upside of inverted U-shaped conductive elastomer exceeds the upper surface of described fixedly wall a little; On described pedestal, be also fixed with a cover plate, when described cover plate is in place, compress the top of described inverted U-shaped conductive elastomer.
In a specific embodiment, described inverted U-shaped conductive elastomer is made of copper.
In a specific embodiment, described cover plate is fixed on described pedestal by screw.
In a further embodiment, described cover plate adopts engineering plastics to make.
The piezoelectric ceramic needle selecting machine of the replaceable piezoelectric ceramic piece in the present invention does not adopt resin material as the fixed sealing material of piezoelectric ceramic piece.When one of them piezoelectric ceramic piece breaks down cisco unity malfunction, can first remove cover plate, then take out inverted U-shaped conductive elastomer, then take out fault piezoelectric ceramic piece.Pack new piezoelectric ceramic piece into pod, then inverted U-shaped conductive elastomer is inserted to translot and make it to coordinate and put in place with piezoelectric ceramic piece, finally cover plate is fixed to and on pedestal, makes it to compress inverted U-shaped conductive elastomer.Therefore, the piezoelectric ceramic needle selecting machine of this structure can conveniently be realized the replacing of single fault piezoelectric ceramic piece, and need when single piezoelectric ceramic piece breaks down, just to piezoelectric ceramic needle selecting machine, not carry out integral replacing, thereby reduces costs.
