Embodiment
Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Shown in please seeing figures.1.and.2; It has demonstrated the concrete structure of the utility model preferred embodiment; The drive unit that a kind of crochet hook that is used to drive wire binding machine moves up and down comprises motor mount 10, servomotor 20, screw mandrel 30, nut seat 40, feed screw nut 50 and swing arm 60, wherein:
Said motor mount 10 is hinged with the frame 1 of wire binding machine; Servomotor 20 is installed on the motor mount 10; The output shaft of servomotor 20 connects with screw mandrel 30 synchronously, and then when servomotor 20 work, the output shaft of servomotor 20 drives screw mandrel 30 and rotates synchronously.
Said screw mandrel 30 is a ball screw, is socketed with two bearings 70 at the output shaft place of accepting with servomotor 20 on this screw mandrel 30, to guarantee the operate as normal of screw mandrel 30.Be pointed out that this screw mandrel 30 also can adopt sliding screw, the bearing 70 of socket on the screw mandrel 30 can also be one, three or more a plurality of, does not limit.
Said nut seat 40 is connected with swing arm 60 rotationally, and said feed screw nut 50 is socketed on the screw mandrel 30 and is installed in the nut seat 40.
The link 61 of said swing arm 60 is hinged with the frame 1 of wire binding machine, and the free end 62 of swing arm 60 is provided with the holder 621 that is used to connect crochet hook 2.
For realizing being rotatably connected of nut seat 40 and swing arm 60, said nut seat 40 is positioned at a side of swing arm 60, and this nut seat 40 extends outward a connecting axle 41; Corresponding, swing arm 60 is provided with a hole 63, and this connecting axle 41 stretches in the hole 63 and can in hole 63, rotate; This connecting axle 41 passes back, hole 63 and from hole 63, stretches out, and the extension location nut 42 that has been threaded is used to prevent that connecting axle 41 from moving to nut seat 40 directions; And; Also be provided with two bearings 80 that are socketed on the connecting axle 41 in this hole 63, be used for guaranteeing that connecting axle 41 can be in the hole 63 rotates normally, certainly; Bearing 80 in the hole 63 also can be one, three or more a plurality of, and concrete quantity can be decided according to actual conditions.
In order to regulate the front and back position of crochet hook 2 in use as required; Further be provided with elongated slot 622 on the free end 62 of said swing arm 60; Corresponding, said holder 621 is provided with corresponding positioning screw 623, and positioning screw 623 passes elongated slot 622 backs and is threaded with swing arm 60; When need are regulated the front and back position of crochet hook 2; Remove earlier being threaded of positioning screw 623 and swing arm 60, then positioning screw 623 is slided on elongated slot 622, slide into to need behind the position again itself and swing arm 60 screwed tight and get final product.
During use, the motor mount 10 of this product is hinged with the frame 1 of wire binding machine, the link 61 of swing arm 60 is also hinged with the frame 1 of wire binding machine; The crochet hook 2 of wire binding machine is fixed on the holder 621 of swing arm 60, when servomotor 20 work, the output shaft forward or reverse of servomotor 20; Drive screw mandrel 30 and rotate synchronously, feed screw nut 50 will be with nut seat 40 to move up or down when screw mandrel 30 forward or reverse, thus on draw or press down swing arm 60; Swing arm 60 pin joint with itself and frame 1 under the effect of nut seat 40 is that circular motion is up or down done in the center of circle, and its movement locus is one section circular arc, thereby the crochet hook 2 of drive fixing on the holder 621 of swing arm 60 moves up and down; Certainly; Moving up and down of crochet hook 2 is not the rectilinear motion at vertical direction, and is circular motion up or down equally, and its movement locus also is one section circular arc; Except vertical direction has displacement; Also have certain displacement in the horizontal direction, and moving up and down under the traction of swing arm 60 of nut seat 40 is circular motion up or down equally; It also has displacement in the horizontal direction; Because the feed screw nut 50 on screw mandrel 30 and the nut seat 40 is connected, motor mount 10 will be that the center of circle moves in a circle with the pin joint of motor mount 10 and frame 1 with servomotor 20, screw mandrel 30, and owing to the opening direction of feed screw nut's 50 screws must be consistent with the length direction of screw mandrel 30; Then nut seat 40 also can be with the certain angle of feed screw nut's 50 rotations when moving in a circle with swing arm 60, and nut seat 40 time rotational connecting axles 41 rotate in hole 63.
The design focal point of the utility model is: this product is done power through adopting servomotor 20; Screw mandrel 30 and feed screw nut 50 that utilization cooperatively interacts do transmission component; Production efficiency is compared with the drive unit of existing employing common electric machine, cam drive assembly and is much improved, and energy-saving and environmental protection, greatly reduces cost; Have the epoch making significance and the extremely strong market competitiveness, help marketing.
Being pointed out that, for more existing wire binding machine with two crochet hooks 2, is that two crochet hooks 2 respectively adopt a drive unit to realize that it moves up and down, and the wire binding machine of the more single crochet hook 2 of effect is more obvious.
The above; It only is the utility model preferred embodiment; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
