The specific embodiment
Embodiment is further described the present invention below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, rapid mould-moving and positioning mechanism comprises fixed form 2, moving die plate 12 and rapid mould-moving oil cylinder 1, between mould shifting oil cylinder piston rod 7 ends and the moving die plate 12 micro-adjusting mechanism is set.
Rapid mould-moving oil cylinder 1 is fixed on the fixed form 2, and rapid mould-moving oil cylinder 1 drives moving die plate 12 quickly opening and closing moulds.
Above-mentioned micro-adjusting mechanism specifically comprises: servomotor 11, worm-and-wheel gear, eccentric wheel 6, contiguous block 14.
One end of rapid mould-moving oil cylinder piston bar 7 ends and clamp nut 3 is fixed, and the other end of clamp nut 3 is connected with contiguous block 14, and contiguous block 14 is connected with deep-slotted chip breaker 61 on the eccentric wheel 6 by connecting axle 5.
Above-mentioned contiguous block 14 is preferably by guide pad 4 guiding that are fixed on the moving die plate 12.
Servomotor 11 is fixed on the servomotor fixed cover 21 as the driver part of micro-adjusting mechanism, servomotor 11 is connected with worm screw 18 by shaft coupling 20, worm screw 18 two ends are by bearing 17 supportings, bearing 17 is fixed on the bearing gland 16,19 at two ends, bearing gland 16,19 is fixedly arranged on the worm gear case 8, sees Fig. 2, Fig. 5.
Worm screw 18 and worm gear 23 engagements, worm gear 23 all is fixed on the worm-wheel shaft 15 by key 22 with eccentric wheel 6, and worm-wheel shaft 15 two ends are by bearing 24 supportings, and bearing 24 is fixed on the two ends gland 13, and gland 13 is fixedly arranged on the worm gear case 8, sees Fig. 6.
The pivot that eccentric wheel 6 is departed from the center of circle of the deep-slotted chip breaker 61 of above-mentioned eccentric wheel 6 is the worm-wheel shaft 15 of worm gear, when eccentric wheel 6 rotates like this, distance between connecting axle 5 worm-wheel shafts 15 in the deep-slotted chip breaker 61 changes, thereby forces the moving die plate of fixing with eccentric wheel 6 12 to move.
