Cam design principle：This cam structure design use roller push rod, can reduce in cam rotary course cam with
Friction between push rod, reduction abrasion.It is the Design of Cam Profiles schematic diagram of the present invention, Fig. 5 b, which are shown, to be cut shown in Fig. 5 a
The theoretical position curve map of screw baffle plate push rod and cam contact point opposing cam axis is changed, the maximum radius of wherein camshaft is poor
Forh, A points are cam lofty perch, and initial position is that the push rod roller of changeable screw baffle plate 403 is contacted with cam A points, now
The push rod roller of changeable screw baffle plate 403 and camshaft contact point are farthest relative to the distance of camshaft axis, in Fig. 5 b couple
The point answered i.e. when corner δ is zero, L be camshaft least radius r0 and semidiameter h's and, the now spiral shell of screw pilot sleeve 5
Nail channel is blocked by changeable screw baffle plate 403；Camshaft continues 45 degree of rotate counterclockwise, now changeable screw baffle plate 403
Push rod roller contacted with cam B points, now the push rod roller of changeable screw baffle plate 403 with camshaft contact point relative to convex
Axle axis it is closest, the corresponding points of Fig. 5 b i.e. when corner δ be 45 degree when, L be camshaft least radius r0, now may be used
Switching screw baffle plate 403 is radially withdrawn, and the screw being stored in screw pilot sleeve 5 can smoothly fall to be installed along screw conduits
With station；To ensure smoothly completing for screw separation next time, camshaft needs to continue 45 degree of rotate counterclockwise, makes changeable spiral shell
Distance of the push rod roller of baffle plate 403 with camshaft contact point relative to camshaft axis is followed closely by recently to farthest, so under
The screw conduits of screw pilot sleeve 5 are blocked by changeable screw baffle plate 403 before one time Screw feeding process starts, so far,
One screw is completed by the band beat automatic feed dividing blanking process of single channel to multichannel, and the blanking cycle is rotate counterclockwise 90
Degree.
Operation principle is as follows：
Screw separation process is broadly divided into two parts：Sleeve rotating feeding process, synchronous blanking process；On sleeve rotating
Material process, motor 1 is rotated clockwise by the drive cam shaft 4051 of shaft coupling 2, is driven ratchet 4052 to rotate clockwise, is promoted spine
Pawl 11 is engaged with ratchet 4052, drives the up time of screw pilot sleeve 5 to rotate, due to camshaft support chassis 404 and screw guiding
Sleeve 5 is fixedly connected by screw, and camshaft support chassis 404, which is driven, to be rotated clockwise, and so far whole feeding system is in electricity
Rotated clockwise under the driving of machine, the screw of now single channel Screw feeding system conveying falls into the screw fairlead of rotation successively
In the screw guide channel of cylinder 5, because the initial position of changeable screw baffle plate 403 is located at the peak of camshaft 4051, and
Changeable screw baffle plate 403 is always zero for the relative velocity of camshaft 4051 during entirely rotating clockwise, therefore
In this feeding process rotated clockwise, changeable screw baffle plate 403 is always positioned at the peak of camshaft 4051, works as up time
Respectively there is one to be hindered to continue to fall by changeable screw baffle plate 403 after pin rotates a circle, in the passage of screw pilot sleeve 5
Screw, now sleeve rotating feeding process complete；Synchronous blanking process, motor 1 is inverse by the drive cam shaft 4051 of shaft coupling 2
Hour hands are rotated, and now promote ratchet 11 to be separated with the motion of ratchet 4052, camshaft 4051 no longer drives the inverse time of screw pilot sleeve 5
Pin is rotated, but due to promoting ratchet and the CONTACT WITH FRICTION of ratchet 4052, therefore to ensure that screw pilot sleeve 5 avoids being rubbed pushing
It is dynamic to rotate counterclockwise, the design of locating snap ring is added herein, when camshaft 4051 is rotated counterclockwise, positioned at screw pilot sleeve
Detent 8 on 5 on lid is contacted with the engagement of locating snap ring 9, therefore hinders what screw pilot sleeve 5 may drive by frictional force
Rotate counterclockwise, because camshaft support chassis 404 is fixedly connected with screw pilot sleeve 5 by screw, therefore cam
Also remains stationary is motionless for axle support chassis 404, and now system can be only done cam axle, drives changeable screw baffle plate 403
The reciprocating motion of radial direction is done, when camshaft 4051 rotates counterclockwise 45 degree, changeable screw baffle plate 403 moves to camshaft
4051 minimum points, at this moment the screw in screw pilot sleeve 5 is while drop to the assembly station of setting, and camshaft 4051 continues inverse
Hour hands rotate 45 degree, and changeable screw baffle plate 403 is re-moved to the peak of camshaft 4051, now the synchronous blanking of screw
Journey is completed.To ensure that changeable screw baffle plate 403 moves to the minimum point process energy of camshaft 4051 in the lofty perch of camshaft 4051
Enough smoothly complete, there is provided baffle plate restoring spring 401, it is ensured that smoothly camshaft 4051 is arrived in playback to changeable screw baffle plate 403
Minimum point, so as to continue to complete next screw when the feeding separation process of passage to multichannel, baffle plate guide 402 ensures
Changeable screw baffle plate 403 does radial alignment reciprocating motion, and system dextrorotation three-sixth turn, rotate counterclockwise 90 is completed
One screw sub-material blanking cycle.
