The specific embodiment
In conjunction with accompanying drawing 1 ~ Fig. 7, preferred embodiment explains further details to the utility model.
Referring to Fig. 1; Be two enforcement structural representation in the utility model; Comprise up and down two relative reducing units 40, each reducing unit 40 comprises vertical servomotor 2, motor vertical holder 3, vertical ball screw 4, down-feed screw nut seat 5, split type take-up housing 6, universal knife rest 7.Wherein vertical servomotor 2, vertical ball screw 4, down-feed screw nut seat 5 form the vertical power set that a cover drives the vertical stroke movement locus.
Fixed bearing has vertical servomotor 2 on the motor vertical holder.The output shaft of vertical servomotor 2 connects vertical ball screw 4 through soft connecting mode, and down-feed screw nut seat 5 is set on the vertical ball screw 4, forms a screw pair, changes rotatablely moving of vertical ball screw 4 into rectilinear motion.Down-feed screw nut seat 5 is connected with split type slide block device 6, drive split type slide block device 6 and do rectilinear motion together, and split type slide block device 6 connects universal knife rest 7, finally drives universal knife rest 7 rectilinear motions.
The soft connection of wherein being mentioned, referring to Fig. 6, its structure mainly comprises shaft coupling head 12, joint 13.Shaft coupling head 12 is the different connection body in aperture, a two, the output shaft of the direct socket of an end and vertical servomotor 2, other end telescopic lap splice 13, whole joint 13 include with shaft coupling head 12 in.Joint 13 is the pipe fitting of an end perforate; The vertical ball screw 4 of the outer end socket of its perforate; Inner through first pin 14 and shaft coupling head 12 pin joints, second pin, 15 pin joints are passed through with vertical ball screw 4 in the outer end of joint 13 simultaneously, and first pin 14 is vertical with 15 one-tenth 90 ° of second pins.Shaft coupling head 12 outsides are bearing in motor vertical holder 3 through bearing 16, and on the vertical ball screw 4 with regard to socket down-feed screw nut seat 5, between bearing 16 and down-feed screw nut seat 5, accompany and cap 17 at interval, it is impaired to eliminate friction.
The slide construction that adopts in the utility model adopts split type slide block device 6, traditional slide block can only be limited with the stroke groove in carry out stroke motion, and can't regulate during wearing and tearing, the branch body structure in the utility model just can address this problem.
As shown in Figure 5, split type take-up housing 6 mainly comprises top shoe 18, regulates gag 19, gag guide bracket 20, sliding block base 21.Wherein top shoe 18 upper surfaces are offered the fixedly cell body 33 that is used to set down-feed screw nut seat 5, and both link into an integrated entity through securing member again.
The sliding tray of being mentioned wherein can also be a V-shaped groove except the shape of said structure dovetail groove simultaneously, rectangular channel or rhombus groove etc., and this mainly changes the shape of regulating gag 19 and gets final product.
Both wings at cutter holder seat 25; Respectively offer a deep-slotted chip breaker 30; The center of circle of deep-slotted chip breaker 30 is positioned at cutter holder seat 25 inside; Be arranged in deep-slotted chip breaker 30 with last reducing slide block 18 fixing cutter holder seat fixed screws 31, whole cutter holder seat 25 is by the cooperate rotation that realize all angles of deep-slotted chip breaker 30 with cutter holder seat fixed screw 31.
In conjunction with Fig. 1, during present embodiment one work, two reducing units 40 can directly be fixed on the front wallboard of wind spring complete machine (when having only a reducing unit 40, equally also can adopt this mode).Two reducing units 40 work alone up and down, when the vertical ball screw 4 of vertical servomotor 2 drivings rotates, force down-feed screw nut seat 5 to drive top shoes 18 and do rectilinear motion, and universal knife rest 7 fixing on the top shoe 18 has also been realized rectilinear motion.
Again referring to Fig. 2, in embodiment two, reducing unit 40 no longer be simple fixation on front wallboard, but set up horizontal power device and slide plate 1 and rectilinear orbit 35.
Slide plate 1 is the pedestal that moves horizontally, and two reducing units 40 are fixed on the same slide plate 1 up and down in present embodiment two, are provided with rectilinear orbit 35 under the slide plate 1, and slide plate 1 is driven by the horizontal power device, is implemented in the slippage on the rectilinear orbit 35.
The horizontal power device comprises horizontal servo motor 8, horizontal ball screw 9, horizontal lead screw nut seat 10, horizontal motor fixing seat 11, and its mounting structure is identical with vertical power set with principle, vertical ball screw 4 and horizontal ball screw 9 be 90 ° vertical.
The vertical direction that in present embodiment two, in embodiment one, realizes drove, the driving that also has horizontal direction when three of both directions are done the time spent simultaneously, transversely drove horizontal lead screw nut seat 10 by horizontal servo motor 8 and is being with slide plate 1 laterally to move.Vertical simultaneously going up by vertical servomotor 2 driving horizontal lead screw nut seats 5 undertaken vertically moving, and reducing slide block 18 vertically moves together with universal knife rest 7 in the drive.After the both direction motion is superimposed, just form a displacement movement locus, realize various adjusting of spring volume footpath radian, avoided the problem that traditional spring coiling machine limited, satisfy the volume footpath requirement of all kinds of springs on the market, the scope of application more enlarges.
Fig. 3 is three shaft-driven another structures in the utility model, is that with the difference of embodiment two form of horizontal power device is different.In this embodiment three, the horizontal power device comprises connecting rod 36, eccentric wheel 37, horizontal servo motor 38.The hinged slide plate 1 of one end of connecting rod 36, the other end and eccentric wheel 37 are hinged, and eccentric wheel 37 rotates, and drivening rod 36 horizontal directions move back and forth, thereby realize slide plate 1 horizontal sliding.And eccentric wheel 37 is driven by horizontal servo motor 38.In this enforcement three, because the setting of eccentric wheel 37, can be so that horizontal servo motor 38 be laid in a side, the wallboard that just in time can set load facility is inner, compactedness and aesthetics when realization equipment assembles like this.
In addition, can find out from Fig. 2 and Fig. 3 that the slide plate 1 of reducing unit 40 can be an integrative-structure up and down, also can be the branch body structure, is integral up and down through connecting plate 39 is affixed, driven by the horizontal power device again.
Participate in Fig. 4, be preferred embodiment in the utility model four, with the difference of embodiment two and embodiment three be that reducing unit 40 independently is installed on the one slide-plate 1 respectively up and down; And each slide plate 1 all disposes a horizontal power device among the embodiment two; Reducing unit 40 drives by vertical and two axis bodies of horizontal direction respectively up and down, four altogether, makes that like this two reducing unit's 40 movement locus are adjustable separately up and down; When the speed of service on the single direction changes; With regard to the two-way displacement track of ability, thus the volume footpath of change spring, and the adjustment precision is higher.
The foregoing description only be used to explain inventive concept of the utility model; But not to the qualification of the utility model rights protection; Allly utilize this design that the utility model is carried out the change of unsubstantiality, (for example substitute vertical ball screw with fork, rack-and-pinion etc. or horizontal ball screw promotes top spring pin) all should fall into the protection domain of the utility model.
