The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: novel nail machine automatic feeding device, be provided with chute 6 at an end of frame 1, be provided with slide plate 2 in it, slide plate and chute are arranged on the base plate of frame in the lump, are provided with the wire feed clamping device on slide plate 2.The wire feed clamping device is located on the clamp base 8, which is provided with jacking block 9, is provided with the fixture block 10 that is attached thereto on jacking block; One side of jacking block is provided with chuck 11 with matching, and chuck 11 is provided with another fixture block 10, and chuck 11 matches with clamp base 8 by the alignment pin 12 of portion located therein.At least be provided with a regulating tank 15 on jacking block 9, jacking block 9 leans on mutually with the push rod 16 of being located at the one side; The vertical setting of feeding direction of regulating tank 15 and steel wire is provided with reference column 17 with matching in it.The front end of chuck 11 has guiding surface 18; The tail end of chuck 11 is provided with screens spring 19, and screens spring 19 is abutted against mutually with the positioning body 20 of being located at the one side.Chuck 11 and positioning body 20 are the setting of α angle with the feeding direction of steel wire, and the size at described α angle is 45 °.
Be provided with tooth bar 3 in the bottom of slide plate 2, its direction is consistent with the transmission direction of steel wire, and tooth bar 3 is meshed with gear 5 on being located at power transmission shaft 4; Power transmission shaft 4 is fixed on the frame 1 by bearing 14, and matched with the end of curved arm rod mechanism; Curved arm rod 7 adopts the sleeve telescoping mechanism, and is connected on the driving shaft by eccentric wheel.Curved arm rod mechanism comprises: be arranged on fork 13 on the frame by pivot pin, be hinged by joint and curved arm rod 7 at fork 13 1 ends, the other end of fork 13 and power transmission shaft 4 are matched, and power transmission shaft 4 is fixed on the frame by bearing 14.Be fixed with wire leading pipe 21 on slide plate 2, the centerline of the center line of wire leading pipe 21 and the charging aperture of nail machine is on same straight line, and the wire feed clamping device is arranged at therebetween.
Its course of work is such: might as well suppose that slide plate 2 is in stroke foremost, this moment, curved arm rod 7 moved forward under eccentric driving, drove fork 13 motions.Fork 13 drives coupled power transmission shaft 4 again and rotates, and the gear of being located on the turning cylinder 45 drives tooth bar 3 motions that are engaged with, thereby realizes moving backward of slide plate 2.Simultaneously, the chuck of wire feed clamping device clamps steel wire by fixture block provided thereon and the fixture block effect of being located on the jacking block of cooperatively interacting under the effect of screens spring.Because the steel wire of clamping is subjected to the component along feeding direction, steel wire is in deadlock position.After one time wire feed is finished, forward another dead point to the eccentric wheel of curved arm rod, the advance rearmost end of Direct Travel of slide plate 2 begins rollback afterwards.During rollback, the chuck of wire feed clamping device is to steel wire deadlock no longer, and steel wire is loosened.When slide plate be in once more stroke foremost the time, repeat said process, go round and begin again.
By adjusting the eccentric eccentric throw that links to each other with curved arm rod, be convenient to the stroke of adjusting slider, to satisfy the demand of processing different size nail length.
