Fig. 2 is two of a stereogram of the present invention;
Fig. 3 is an exploded view of the present invention.
[specific embodiment]
Describe the present invention below in conjunction with accompanying drawing:
As shown in Figure 1, electric discharge machine clamp includes the support 1 that can be connected with the electric spark horn, and support 1 mainly is with on the electric discharge machine horn is connected, and plays a connector effect.Below support 1, be connected with upper junction plate 2; Below upper junction plate 2, be provided with portable plate 3, on portable plate 3, be provided with the collets 7 that insulate with the electric discharge machine workbench, come work because electric discharge machine mainly is the spark that leans on positive and negative two utmost points to be produced; So an electrode is arranged on the electric discharge machine workbench; Be another electrode on the electric discharge machine horn,, prevent to produce between them spark so will lean on collets 7 to separate.
On upper junction plate 2, be provided with lead 8, on portable plate 3, be provided with pilot hole 10, lead 8 slides in pilot hole 10, makes upper junction plate 2 and portable plate 3 make relative rectilinear motion, and it all does to move stably between the two.
On portable plate 3, be provided with electrode stem 4; End at electrode stem 4 is provided with machined electrode 5; This machined electrode 5 is shaped as falcate in the present embodiment; The tail end of machined electrode 5 is point relatively, leans on the tip of machined electrode 5 and need produce spark between the part of processing, conveniently processes the accurate part of comparison.
On upper junction plate 2 and portable plate 3, be provided with the linkage 6 that can let electrode stem 4 produce arching trajectorys.Said linkage 6 include the tooth bar 61 that is located at upper junction plate 2 be located on the portable plate 3 with tooth bar 61 meshed gears 62, the flexible rotation that will driven gear 62 of tooth bar 61.On the axle of this gear 62, be connected with a cam 63; Said electrode stem 4 is connected on the other end of cam 63; The rotation of gear 62 will drive the rotation of cam 63 like this, and the rotation of cam 63 will drive the electrode stem 4 that is connected cam 63 other ends and do the circumference rotation.Between upper junction plate 2 and portable plate 3, be provided with the elastic component 64 that lets portable plate 3 reset, this elastic component 64 is a spring.On upper junction plate 2, be provided with the gag lever post 9 that portable plate 3 is coupled together; Described elastic component 64 is that spring housing is in gag lever post 9; When elastic component 64 resets to a certain degree; Under the effect of gag lever post 9, upper junction plate 2 and portable plate 3 do not remake mobile, and elastic component 64 also keeps certain elastic force.
Said collets 7 are two, and it is separately fixed at the both sides of portable plate 3, and are stressed so even.
Its course of work is: the part of the integral body that will process is placed and is fixed on the workbench; And on this practical horn that is connected electric discharge machine; The electrode that has a high pressure on the horn; The electrode that has another high pressure on the workbench utilizes the vertical and horizontal of horn to move some simple faces of processing like this.In the time will being worked into the inside of part, horn descends, and collets 7 contact with workbench; Regulate the incision angle at the tip of machined electrode 5, horn descends again afterwards, and the tooth bar 61 that is positioned on the upper junction plate 2 moves down; And portable plate 3 is spacing by workbench, can not move the rotation that then tooth bar 61 will driven gear 62; The rotation of gear 62 will drive electrode stem 4 and do the circumference rotation; Then the machined electrode 5 on the electrode stem 4 will with produce electric spark at processing parts, the high temperature of spark will melt away metal, like this machined electrode 5 just at leisure, pursue and go deep into part inside ashamedly; So just can process the deep-slotted chip breaker that is shaped as C shape, and the precision of processing is very high.When the past rising of horn, under the effect of back-moving spring, tooth bar 61 is done reverse moving, and then driven gear 62 backward rotation set back machined electrode 5.
