When solving the ring mould that exists in prior art more changing device move in orbit, on traffic direction, skid, the problem of deflection, it is a kind of for encircling more a kind of rack and pinion drive of changing device traveller of mould that the utility model provides, according to this rack and pinion drive, by rack and pinion engagement, carry out transferring power, during stopping brake, both sides gear mechanism connects, and guarantees Complete Synchronization operation.
Specific embodiments is as follows:
Encircle a more rack and pinion drive for changing device traveller of mould, described ring mould more changing device traveller at least comprises: be fixed on motor, break, speed reducer, transmission shaft, rack and pinion drive on car body girder; Described rack and pinion drive comprises gear, tooth bar, gland; Wherein said tooth bar is for being arranged side by side on the crossbeam base plate of both sides, and by bolton, locating stud is located.
According to rack and pinion drive of the present utility model, in rack and pinion engagement process, by the gland cylindrical being assembled together with gear, at tooth bar sidepiece horizontal plane, roll and guaranteed the gap of wheel and rack engagement, as two gear engagements, be equal to the centre distance that has guaranteed two gears.
Preferably, described gear rack is arranged in the more both sides of changing device of ring mould.
Preferably, be processed with "T"-shaped groove below described tooth bar, by bolton on crossbeam base plate.
Preferably, described gear is assemblied in transmission shaft two ends.
Preferably, gear rack is arranged in the more both sides of changing device of ring mould, device traveller adopts concentrated transmission scheme, adopt a motor, speed reducer to drive both sides transmission shaft simultaneously, then drive two side gears on tooth bar, to rotate simultaneously, this mechanical type is synchronous, when having guaranteed ring mould more changing device moving in orbit, on traffic direction, can not skid, skewness.
Accompanying drawing explanation
By describe example embodiment of the present utility model in detail with reference to accompanying drawing, above and other feature of the present utility model and advantage will become more obvious, in the accompanying drawings:

Fig. 3 is the plan view of tooth bar;
Fig. 4 is the right elevation of tooth bar;
In figure, the corresponding component of numeral number or toponym are as follows:
1, motor; 2, break; 3, speed reducer; 4,4 ' transmission shaft; 11,11 ' tooth bar; 12,12 ' gear; 13,13 ' gland; 21, "T"-shaped groove; 22, sidepiece horizontal plane; 31,31 ', car body track; 32, hydraulic lift
Embodiment
Below in conjunction with the accompanying drawing in the utility model preferred embodiment, technological scheme to the utility model preferred embodiment is clearly and completely described, obviously, described preferred embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
The words such as " first " mentioned in specification, " second " are only for distinguishing the difference of scheme,, as the judgement of time sequencing, position relationship and priority height, the word indications such as " position 1 ", " position 2 " in same literary composition, " upper " " the next " are not with respect to the orientation in accompanying drawing.
Figure 1 shows that according to the drawing machine ring mould of the present utility model partial schematic diagram of changing device more, particularly, above-mentioned partial schematic diagram is the drawing machine ring mould schematic diagram of changing device more when looking from front; Figure 2 shows that the more integral right view of changing device of drawing machine ring mould.
Shown in Fig. 1, Fig. 2, Fig. 3, drawing machine ring mould more changing device traveller comprises: motor 1, break 2, speed reducer 3, transmission shaft 4,4 ', tooth bar 11,11', gear 12,12', gland 13,13'.Its middle rack 11,11', gear 12,12', gland 13,13' form rack and pinion drive.
Motor 1 provides power, by speed reducer 3, transmission shaft 4,4 ' is rotated, and transmission shaft 4,4 ' driven gear 5,5 ' rotate on tooth bar 11,11', thus band rotating ring mould more changing device on car body track 31,31 ', move reciprocatingly.Ring mould more changing device has three parking spaces, be respectively and wait for position, position 1, position 2, work cycle is for moving to position 1 from wait position, by hydraulic lift 32 from the next ring mould that hoists, hoist to after upper, travelling mechanism driving ring mould more changing device from position 1 to position 2, then will encircle mould places the next from upper by hydraulic lift 32, complete half of circulation, after ring mould is used, in the time of need to changing the different ring mould of another diameter, ring mould more changing device by hydraulic lift 32 by ring mould from position 2 the next slinging, travelling mechanism driving ring mould more changing device from position 2 to position 1, to encircle mould 1 upperly places the next by hydraulic hoist unit 32 from position, complete whole work cycle.
According to rack and pinion drive of the present utility model, utilize gear 12,12 ' above to move at tooth bar 11,11 ', two side gears 12,12 ' all turn over the identical number of teeth, have guaranteed that the displacement that more pass by changing device both sides on traffic direction of ring mould is identical.Rack and pinion drive has replaced original car body to rely on adhesion wheel and track friction to produce the mode of power.Rack and pinion drive, in conjunction with horizontally-guided wheel apparatus, has improved the more positioning precision of changing device of ring mould greatly, has reached object accurate, quick-replaceable ring mould.
