Embodiment
The below is elaborated to embodiments of the invention:
As shown in Figures 1 to 4, a kind of capacitor fixture, the left jig arm 10 and the right jig arm 10 that comprise chuck body 1 and be positioned at described chuck body 1 both sides, on described chuck body 1, have side by side two first through holes 101, in two first through holes 101, be respectively equipped with a guide shaft 2, one of them described guide shaft 2 is fixedly linked with left jig arm 10, another described guide shaft 2 is fixedly linked with right jig arm 10, be equipped with tooth bar 201 on described two guide shafts 2, be provided with in the cavity in the described chuck body 1 with described two guide shafts 2 on the gear 3 that is meshed simultaneously of tooth bar 201, described gear 3 is provided with for opening of transmitting gear 3 and presss from both sides swing arm 10, be provided with a ring flange 5 that is used for covering described gear 3 in described chuck body 1, so that gear 3 is hidden in chuck body 1 inside, can be dustproof, prevent that lubricating oil from leaking outside, keep greasy property good, the anchor clamps ectosome is attractive in appearance.Wherein, as shown in Figure 1, drive folder and have deep groove ball bearing 8 in the swing arm 4, open between folder swing arm 4 and the gear 3 and link to each other by bearing, be equipped with for the charging unit to 9 chargings of electric capacity workpiece in the end of described left jig arm 10 and right jig arm 10, charging unit comprises left charging end and right charging end.When external force transmission deep groove ball bearing 8, so promote to open folder swing arm 10, gear 3 rotations, so two guide shafts 2 move and stagger, left jig arm 10 and right jig arm 10 are opened, and and then open left charging end and right charging end, put electric capacity workpiece 9 into, then, the application of force in the other direction, counter-rotation gear 3, contact on the jig arm 10 just clamps described electric capacity workpiece 9, just can automatically finish charging, test to electric capacity workpiece 9, it is simple in structure, and automaticity is high.
Wherein, described left charging end and right charging end include two collets 13, be fixed on inner core contact 11 on each collets 13 and two outer core contacts 7 of inner core contact 11 both sides, all rigid connecting is connected to two copper billets 14 on described each collets 13, one of them copper billet 14 is electrically connected with inner core contact 11 on these copper billet 14 place collets 13, inner core contact 11 contacts with the inner core 92 of electric capacity workpiece 9, another copper billet 14 is electrically connected with two outer core contacts 7 on these copper billet 14 place collets 13, two outer core contacts 7 contact with the outer core 91 of electric capacity workpiece 9 respectively, between the inner core 92 of electric capacity workpiece 9 and outer core 91, be provided with barrier film 94, barrier film 94 prevents inner core 92 and outer core 91 guide pin bushings, and can be gone between to charging circuit and test circuit by copper billet 14, high-voltage charging and low voltage experiment contact point can be separated, and then can improve measuring accuracy.Described each collets 13 all by offer on its end location hole 15 usefulness keepers respectively with detachable being located by connecting of described left jig arm 10 and right jig arm 10 ends.As shown in Figure 3, the location hole 15 of opening on the end of described each collets 13 is 3, therefore the length of the electric capacity workpiece of clamping selects the location hole 15 that the position is fit on the collets 13 to connect left jig arm 10 and right jig arm 10 and collets 13 as required, therefore is fit to the electric capacity workpiece 9 of different length.
All have a thimble 111 on described each inner core contact 11, be inserted into by this thimble 111 in the centre bore 93 of inner core of twin-core bud electric capacity workpiece, positioning accuracy is high.All overlap on described each outer core contact 7 spring is arranged, the boss that has on the described outer core contact 7 of described spring one end butt, the other end is supporting described collets 13, therefore outer core contact 7 has flexible function, can clamp the outer core 91 of twin-core bud electric capacity workpiece 9, core contact 7 problem poor with the outer core contact performance of twin-core bud electric capacity workpiece 9 outside avoiding when the luxuriant electric capacity workpiece 9 of twin-core is uneven owing to core 91 outside it is so that outer core contact 7 is good with outer core 91 contact performancies of electric capacity workpiece 9.
As shown in Figure 2, be provided with an extension spring 6 between described left jig arm 10 and the right jig arm 10, one end of described extension spring 6 links to each other with left jig arm 10, its other end links to each other with right jig arm 10, and when using pneumatic mechanism to promote to open folder swing arm 4, left jig arm 10 and right jig arm 10 are opened, put into electric capacity workpiece 9, by extension spring 6 pulling force effects, can make tighter with 9 clampings of electric capacity workpiece of outer core contact, and external force backward rotation gear 3 makes the contact clamping electric capacity workpiece 9 to need not to apply in the other direction at deep groove ball bearing 8.Simultaneously, in described chuck body 1, also have two second through holes 102, in two second through holes 102, be respectively equipped with a compressing spring 17, wherein an end of a compressing spring 17 links to each other with chuck body 1, and its other end links to each other with left jig arm 10, and an end of another root compressing spring 17 links to each other with chuck body 1, the other end of described another root compressing spring 17 links to each other with right jig arm 10, like this by compressing spring 17 pulling force effects, can make tighter with 9 clampings of electric capacity workpiece of contact, contact performance is good.At described two compressing springs, the 17 interior guide rods 12 that all are arranged with, wherein a guide rod 12 is fixedly linked with left jig arm 10, another root guide rod 12 is fixedly linked with right jig arm 10, plays the guide-localization effect when left and right jig arm 10 motion, prevents compressing spring 17 stressed flexural deformations.
Described two second through holes 102 below that is opened in described two first through holes 101 side by side, and second through hole 102 at compressing spring 17 places that first through hole 101 at described guide shaft 2 places that left jig arm 10 links to each other links to each other with right jig arm 10 is at same vertical plane, second through hole 102 at compressing spring 17 places that first through hole 101 at described guide shaft 2 places that right jig arm 10 links to each other links to each other with left jig arm 10 is at same vertical plane, like this so that left jig arm 10 and right jig arm 10 are stressed more balanced.
Another object of the present invention is to provide a kind of twin-core bud electric capacity machine of automatically energizing, and it has a plurality of capacitor fixtures, has this kind capacitor fixture, this kind machine good clamping effect of automatically energizing, and automaticity is high.
The above embodiment has only expressed the specific embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
