The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1~Figure 33, the present invention includes support 1, last Wire Wheel mechanism 2, following wire agency 3, assistant director of a film or play's wheel assembly 4, line sending electric machine assembly 5, spring pitch shaping rod assembly 6, thread trimmer 7, Wire Wheel shaft transmission 31, wire guide cutter 32, control circuit, spring diameter builder and spring pitch and be shaped and cutting mechanism.
Among Fig. 6~Figure 28, spring pitch is shaped and cutting mechanism comprises spring pitch be shaped excellent guide pillar 8, spring pitch shaping rotating disk 9, two guide pillars fixedly slide block 10,11, guide pillar movable slider 12, two guide pillar fixed stops 13,14, support fixed stop 15, four connecting rods 16,17,18,19, back-moving spring 20, scissors armed lever 21, the shaping of spring pitch and shear motors 22, gearbox 23 etc.Guide pillar fixedly slide block 10 and 11 is fixed on the support 1, and the spring pitch excellent guide pillar 8 that is shaped is bearing in guide pillar fixedly on the slide block 10 and 11, can slide thereon, and the one end is connected with spring pitch shaping rod assembly 6.Guide pillar movable slider 12 is sleeved on spring pitch and is shaped on the excellent guide pillar 8, can slide on it.Guide pillar fixed stop 13 and 14 is fixed in spring pitch and is shaped on the excellent guide pillar 8; The borehole jack of support fixed stop 15 by the centre is loaded on spring pitch and is shaped on the excellent guide pillar 8, between two guide pillar fixed stops 13 and 14, and is fixed on the support 1.Back-moving spring 20 is loaded between guide pillar fixed stop 13 and the support fixed stop 15.Spring pitch shaping rotating disk 9 is shaped with spring pitch and shear motor 22, gearbox 23 interlocks, and by connecting rod 16 and guide pillar movable slider 12 interlock mutually.Connecting rod 17 1 ends are articulated on the support 1, and the other end and connecting rod 18 articulate, and the other end of connecting rod 18 and scissors armed lever 21 articulate; One end of connecting rod 19 and guide pillar movable slider 12 articulate, and the pivoting point of the other end and connecting rod 17 and connecting rod 18 articulates.
During real work, adjust the position (change of this position can make the pitch of spring change) of spring pitch shaping rod assembly 6 as need, can be shaped and shear motor 22 (servomotor) rotation by control circuit control spring pitch, rotate thereby drive spring pitch shaping rotating disk 9.See Fig. 6, spring pitch shaping rotating disk 9 is in initial position, among Fig. 7, machine is being carried spring wire, and spring pitch shaping rotating disk 9 rotates counterclockwise, and promotes guide pillar movable slider 12 and travels forward, spring pitch shaping rod assembly 6 is pushed away synchronously, the spring leading portion pitch of formation is increased; Scissors armed lever 21 since the drive of connecting rod 18 to the counter clockwise direction turn.Among Fig. 8, continue to carry spring wire, spring pitch shaping rod assembly 6 to be pushed to before, make the spring stage casing pitch of formation reach the maximum state; Shearing armed lever 21 is because the drive of connecting rod 18 rotates to maximum to counter clockwise direction.Among Fig. 9, continue to carry spring wire, spring pitch shaping rotating disk 9 clockwise rotates, and spring pitch shaping rod assembly 6 is shunk back backward, and the rear pitch that forms spring is reduced; Shearing armed lever 21 since the drive of connecting rod 18 to the clockwise direction turn.Among Figure 10, machine is prepared to stop to carry spring wire, and spring pitch shaping rod assembly 6 is shunk back backward to the rearmost position, and the rear pitch that forms spring reduces to minimum state; Shearing armed lever 21 is because the drive of connecting rod 18 continues to allow thread trimmer 7 near wire guide.Among Figure 11, after Wire Wheel stops to carry spring wire, because guide pillar fixed stop 14 is stopped by support fixed stop 15, can not allow the spring pitch excellent guide pillar 8 that is shaped continue to shrink back backward, therefore the backward rotation of spring pitch shaping rotating disk 9 also only allows guide pillar movable slider 12 move backward, by the pivoting point of connecting rod 19 pulling connecting rods 17 with connecting rod 18, thus allow connecting rod 18 drive scissors armed lever 21 to the clockwise direction turn to the angle of cutting off wire rod, thereby cut off wire rod by thread trimmer 7.And spring pitch shaping rod assembly 6 also is retained in the position that begins to send spring wire, has waited for the manufacturing of individual spring to begin.
Among Figure 29~Figure 33, the spring diameter builder comprises spring diameter shaping rotating disk 24, spring diameter formed conductor wheel 25, spring diameter formed conductor wheel guide pillar 26, spring diameter formed conductor wheel sliding support 27, connecting rod 28, spring diameter forming motor 29, gearbox 30 etc.Spring diameter formed conductor wheel 25 is clipped in the spring diameter formed conductor wheel sliding support 27, spring diameter formed conductor wheel sliding support 27 is loaded on the spring diameter formed conductor wheel guide pillar 26, can slide thereon, spring diameter shaping rotating disk 24 links with spring diameter forming motor 29 and gearbox 30, and is connected by connecting rod 28 and spring diameter formed conductor wheel sliding support 27.
Among Figure 29, spring diameter shaping rotating disk 24 clockwise rotates under the drive of spring diameter forming motor 29 and gearbox 30, thereby on spring diameter formed conductor wheel guide pillar 26, slide backward by connecting rod 28 drive spring diameter formed conductor wheel sliding supports 27 and spring diameter formed conductor wheel 25, thereby make spring diameter formed conductor wheel 25 further from 32 outlets of wire guide cutter, formed spring diameter is for bigger.Among Figure 30, spring diameter shaping rotating disk 24 rotates counterclockwise, thereby makes spring diameter formed conductor wheel 25 comparatively near 32 outlets of wire guide cutter, and formed spring diameter is less.
Control circuit can be controlled the action of line sending motor, the shaping of spring pitch and servomotors such as shear motor 22 and spring diameter forming motor 29 in the line sending electric machine assembly 5, is existing Stepping Motor Control technology, no longer narration.
