The specific embodiment
The utility model proposes and a kind ofly drive slide block along the printing platform turnover mechanism that line slideway moves by toggle, printing platform is fixedly installed on this slide block, thereby realizes printing platform moving around between contraposition position and printing position.
Fig. 1 a-Fig. 1 c shows the transmission principle figure that printing platform of the present utility model passes in and out mechanism.As shown in Figure 1a, this printing platform turnover mechanism mainly comprises slide block 3 and linkage 5 and the crank mechanism 7 that is slidingly connected with frame 1, printing platform 2 is fixedly connected so that move with slide block 3 with slide block 3, the two ends of linkage 5 are rotationally connected with slide block 3 and crank mechanism 7 respectively, and crank mechanism 7 is driven by the drive motors (not shown) of fixedlying connected with frame 1.Thus, the rotation of crank mechanism 7 drives linkage 5, and then makes printing platform 2 move with slide block 3 straight line on frame 1.
When crank mechanism 7 turns to position shown in Fig. 1 b, i.e. crank mechanism 7 and linkage 5 expansion in alignment move to limit on the right-right-hand limit position on the frame 1 with printing platform 2.When crank mechanism 7 Rotate 180 degree turned to position shown in Fig. 1 c, promptly crank mechanism 7 was in alignment and overlapping with linkage, and printing platform 2 is moved to limit on the left position on the frame 1.This limit on the right-right-hand limit position and limit on the left position just can be defined as respectively the contraposition position of printing platform and printing position one of them.Therefore, the utility model just can be realized the switching of printing platform between contraposition position and printing position, repetitive positioning accuracy height by 180 degree rotations of crank mechanism.
Fig. 2 and shown in Figure 3 be structural representation according to the printing platform of an embodiment of the utility model turnover mechanism.As shown in Figure 2, printing platform 20 is fixedly mounted on the installing plate 32, and is slidingly connected on the frame 10 by installing plate 32.Be specially, the bottom of installing plate 32 is arranged with two slide blocks 34, respectively be fixed on that two parallel line slideway 12 is slidingly connected on the frame 10.Line slideway 12 extends along the direction that printing platform 20 needs to move.
Further, as shown in Figures 2 and 3, the bottom of installing plate 32 also is fixed with connecting plate 36, this connecting plate 36 is connected with crank mechanism 70 by linkage 50. and this linkage 50 comprises first connecting rod 52 and second connecting rod 56, first connecting rod 52 is locked together by jockey 54 with second connecting rod 56 relative the inners, and can unclamp the total length that first connecting rod 52 and second connecting rod 56 are regulated in jockey 54 backs. this crank mechanism 70 comprises rotating shaft 72 and crank 74, rotating shaft 72 be used for be fixed on frame on the output shaft of motor be connected so that drive source to be provided, crank 74 is fixedlyed connected to rotate with the rotation of rotating shaft 72 with rotating shaft 72. and, first end of linkage 50 (being the outer end of first connecting rod 52) is rotationally connected with connecting plate 36 by first connector 40, and second end of bar linkage structure 50 (being the outer end of second connecting rod 56) is rotationally connected with crank 74 by second connector 60.
Therefore, when crank 74 rotates with the rotation of rotating shaft 72, crank 74 rotates via the outer end of second connector, 60 traction second connecting rods 56 thereupon together, thereby the outer end that drives first connecting rod 52 is via first connector, 40 traction connecting plates 36, and then installing plate 32 and printing platform 20 feasible and that connecting plate 36 is fixed move along line slideway 12.
Fig. 4 is the concrete structure schematic diagram according to the printing platform turnover mechanism of an embodiment of the utility model.Specifically illustrated the rotation connection structure between first connecting rod 52 and the connecting plate 36 among Fig. 4, and the rotation connection structure between second connecting rod 56 and the crank 74.
As shown in Figure 4, this embodiment is by screw rod 42 be rotationally connected connecting plate 36 and first connecting rod 52.The upper end of screw rod 42 is fixing by being threaded with the lower end of connecting plate 36, and the lower end of screw rod 42 is installed in by bearing 44 and bearing insert 46 in the axis hole of first connecting rod 52 outer ends and realizes being rotationally connected.Like this, be connected between first connecting rod 52 and the connecting plate 36 and relatively rotating around screw rod 42 can be taken place.Equally, adopted identical syndeton to realize being rotationally connected between second connecting rod 56 and the crank 74.The upper end of screw rod 62 is fixing by being threaded with the outer end of second connecting rod 56, the lower end of screw rod 62 is rotationally connected by the outer end of bearing 64 and bearing insert 66 and crank 74, thereby making to be connected between second connecting rod 56 and the crank 74 also, relatively rotating around screw rod 62 can be taken place.
Being an example that is rotationally connected that realizes between connecting plate 36 and first connecting rod 52 and second connecting rod 56 and the crank 74 shown in 4, is not to be to restriction of the present utility model.Obviously, being rotationally connected between connecting plate 36 and first connecting rod 52 and second connecting rod 56 and the crank 74 can also be realized by various other suitable manner.
Fig. 5 is the perspective view according to the running part of the printing platform turnover mechanism of an embodiment of the utility model.As shown in Figure 5, connecting plate 36 is fixedly mounted on the lower surface of installing plate 32 by fixed head 38.And connecting plate 36 is rotationally connected by connector 40 and first connecting rod 52, and second connecting rod 56 is rotationally connected by connector 60 and crank 74.
Further, specifically illustrated syndeton between first connecting rod 52 and the second connecting rod 56 among Fig. 5.As shown in Figure 5, the inner of first connecting rod 52 is formed with an open slot 522, and contiguous block 542 is embedded in this open slot 522 and passes through screw or existing alternate manner and first connecting rod 52 lockings.The inner of second connecting rod 56 forms screw rod 562, the interior realization of tapped through hole that screws in contiguous block 542 centers is threaded, by the locking nut 544 and 546 at locking contiguous block 542 two ends, just second connecting rod 56 can be fixedlyed connected with contiguous block 542 then, also promptly fixedly connected with first connecting rod 52.
So syndeton makes that the total length between first connecting rod 52 and the second connecting rod 56 is adjustable.After unclamping locking nut 544 and 546, rotation second connecting rod 56 makes the screw rod 562 of second connecting rod 56 screw in gradually with respect to contiguous block 542, just can change the length overall between first connecting rod 52 and the second connecting rod 56.Therefore, the open slot 522 on the first connecting rod 52 need be longer than contiguous block 542, regulates the space so that reserve enough length of connecting rods.After being adjusted to required total length, locking locking nut 544 and 546 just can be fixed this length.
Being an adjustable example of fixedlying connected that realizes between first connecting rod 52 and the second connecting rod 56 shown in 5, is not to be to restriction of the present utility model.Obviously, can also realize length-adjustable fixedlying connected by various other suitable manner between first connecting rod 52 and the second connecting rod 56.The length-adjustable benefit of linkage is, when machine is installed and debug, the left and right sides extreme position of printing platform turnover has had the adjustment amount of certain limit, helps the error that remedies and accumulate in assembling process, and the center line of printing platform aligns with the center line of half tone when guaranteeing printing.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
