A kind of pneumatic normally opened clip of formula wire electrode that rises
Technical field
The present invention relates to a kind of pneumatic normally opened clip of formula wire electrode that rises, it is adaptable to electric spark machining field.
Background technology
The wired clamp of normally opened auxiliary of electric spark machine tool traditional design, is typically all and uses solenoid actuated one piece to mould
Material thread pressing block by wire electrode compression clamping on fixed block, with ensure wire electrode do not have normally closed clip is opened when by
The relative motion caused in gravity or other friction, processes this clamp during silk at remaining and is in opening shape
State, owing to its wired dynamics is little and locus is limited, often can only use mini push type electric magnet, time length electricity
Magnet easily lost efficacy and caused the precision being failure to actuate thus have influence on into silk processing.
Summary of the invention
Purpose: in order to overcome above deficiency, it is considered to the demand of reality, the invention provides a kind of pneumatic formula electrode that rises
The normally opened clip of silk, simplifies product structure design, improves the reliability into silk processing and service life, reduces production cost.
Technical scheme:
A kind of pneumatic normally opened clip of formula wire electrode that rises, is arranged in guider fixed block, including fixed support, two fairleads,
Rubber grips, die cavity and guider, described guider fixed block is connected to below fixed support, and has in guider fixed block
Die cavity, described rubber grips is arranged in die cavity, and said two fairlead is arranged on the two ends of rubber grips, and respectively with fixing
Support and guider connect, and described guider is arranged on guider fixed block lower end, and described air inlet is opened in guider and fixes
The side of block, and connect with die cavity, the rubber grips that wire electrode is each passed through between two fairleads and two fairleads is passed through
In guider.
Preferably, use can the abrasive rubber material of deformation for described rubber grips.
Beneficial effect: the present invention provides a kind of pneumatic normally opened clip of formula wire electrode that rises, and substitutes traditional normally opened wired clamp,
It is effectively improved reliability and the service life of normally opened clip, thus reaches to simplify product structure design.

Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in the application, real below in conjunction with the application
Execute the accompanying drawing in example, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described enforcement
Example is only some embodiments of the present application rather than whole embodiments.Based on the embodiment in the application, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, all should belong to the application protection
Scope.
As it is shown in figure 1, a kind of pneumatic normally opened clip of formula wire electrode that rises, it is arranged in guider fixed block 1, including fixing
2, two fairleads 4 of frame, rubber grips 5, die cavity 6 and guider 7, described guider fixed block 1 is connected to fixed support 2 times
Side, and in guider fixed block 1, have die cavity 6, described rubber grips 5 is arranged in die cavity 6, and said two fairlead 4 is arranged
At the two ends of rubber grips 5, and being connected with fixed support 2 and guider 7 respectively, described guider 7 is arranged on guider and fixes
Block 1 lower end, described air inlet 7 is opened in the side of guider fixed block 1, and connects with die cavity 6, and wire electrode 3 is each passed through two
Rubber grips 5 between individual fairlead 4 and two fairleads is passed through in guider 7.
Preferably, use can the abrasive rubber material of deformation for described rubber grips 5.
The clamping of the art of this patent wire electrode be applicable to electric spark capillary processing, wire electrode diameter is applicable to 0.3mm
Above, as it is shown in figure 1, whole normally opened clip is connected on fixed support 2, and it is connected with wire feeding device by fixed support 2, electrode
Silk 3 passes through guider 7 from the fairlead 4 at the two ends of rubber grips 5, rubber grips use a kind of can be with deformation
Abrasive rubber material, when compressed air enters into die cavity 6 from air inlet 8, and air pressure makes rubber grips 5 to wire electrode 3
Circumferencial direction deforms thus reaches clamping effect, and after compressed air pressure release, rubber grips 5 recovers elastic deformation so that electricity
Polar filament 3 can the most smooth and easy motion.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
