Description
Technical field
The present invention relates to a kind of tire building technology, relate in particular to a kind of tire assembly drum that drives the motion of outer watt of realization radial telescopic type by Neva.
Background technology
At present, the folding of tire assembly drum drum mode comprises inertia folding drum and machinery folding drum.Inertia folding drum is simple in structure, the folding drum is convenient but impact moment is big, the life-span is short, automaticity is low.The machinery folding drum relative rubbing main shaft of employing and brake cover, cylinder or hydraulic cylinder transmission, control is convenient, expansion is continuous, but needs to add auxiliary equipment, the structural complexity height, impact wear is big, maintenance of equipment rate height.For overcome in the above-mentioned general machinery folding drum mode existing such as assembly drum when folding a big drum watt elder generation support outward, thereby destroy the steel wire of tire easily through broadwise; And the folding back of assembly drum is out of round, causes the tread flaking difficulty; Need motive power big, reduce service life; A drum watt folding back produces interferes, need slice off technical problems such as a big chunk, patent No. ZL200820020630.5, its notification number is to disclose a kind of tire assembly drum in the Chinese utility model patent of CN201195398Y, comprise main shaft and guide rod, the main shaft two ends connect two positioning disks by key, guide rod is in main shaft inside, sliding sleeve is enclosed within on the main shaft, the stroke slotted hole is arranged on the main shaft, keyhole is arranged on the guide rod, guide rod links together by driving key and sliding sleeve, spaced ear staggers before and after sliding sleeve has, the front end ear is connected with little link rod by bearing pin, and little link rod is connected with the big drum frame by bearing pin, and the rear end ear is connected with big link rod by bearing pin, big link rod is connected with the side drum frame by bearing pin, side drum frame and big drum frame are spaced on circumference, and positioning disk is provided with gathering sill, insert feather key in the gathering sill, feather key is connected with bulging frame, and the drum frame connects bulging watt outward.The enforcement of technique scheme mainly is: guide rod, and sliding sleeve, the mechanism that little link rod, big drum frame are formed makes that under the driving of guide rod the drum watt (outer watt) that is connected with the big drum frame can circumferentially extending or contraction; Guide rod, sliding sleeve, big link rod, the drum that is connected with the side drum frame watt (Neva) that the mechanism that the side drum frame is formed makes under the driving of guide rod can circumferentially extending or contraction; Assembly drum shrinks the staggered stack of back watt plate rounding in a border circular areas.In this kind assembly drum, the motion of Neva and outer watt is that same guide rod drives two groups of link rod (little link rods, big link rod) causes, assembly drum contraction process in, the acceleration of one group of watt of plate (Neva) is bigger than other one group of watt of plate (outer watt) all the time, the space that causes shrinking between the two groups of watts of plates in back is bigger, and the mechanism after the contraction is compact inadequately, can not well satisfy production requirement.Be provided with guiding mechanism in the above-mentioned tire assembly drum, guiding mechanism has also strengthened the overall weight of complete machine in the shrinkage degree that has limited assembly drum.
Summary of the invention
At above-mentioned prior art, the invention provides a kind of tire assembly drum that drives the motion of outer watt of realization radial telescopic type by Neva, tire assembly drum of the present invention be a kind of after contraction the more compact forming drum mechanism of its structure, have simple in structure, weight is lighter, be convenient to unload tire, the motion control characteristic of simple.
In order to solve the problems of the technologies described above, the technical scheme that radial telescopic type tire assembly drum of the present invention is achieved is: be made up of Neva and Neva driving mechanism and outer watt and an outer watt driving mechanism, described Neva driving mechanism comprises hollow main shaft, be provided with leading screw in the described hollow main shaft, it is identical that the two ends of described leading screw are respectively arranged with pitch, the screw thread that rotation direction is opposite, the position that aligns with described two sections screw threads on the described hollow main shaft is respectively equipped with groove, be combined with nut respectively on two sections screw threads, described two nuts are inlaid in respectively in the described groove, be equipped with sliding seat on two nuts, be hinged with a connecting rod A and two connecting rod B that are parallel to each other between each sliding seat and the described Neva respectively; Described two connecting rod B that are parallel to each other and described sliding seat and described Neva are by hinged formation one parallelogram linkage of hinge; Described connecting rod A and described connecting rod B are isometric, and the axial symmetric arrangement of the relative Neva with connecting rod A of a connecting rod B wherein; Described outer watt driving mechanism is included in two cross supporting frames with horizon bar and vertical rod of the inboard symmetric arrangement at outer watt axial two ends, the described relatively outer watt radial symmetric of described cross supporting frame is arranged, between the upper end of the vertical rod of described cross supporting frame and outer watt for being rigidly connected, the two ends of the horizon bar of described cross supporting frame are fitted with sliding sleeve C and sliding sleeve D respectively symmetrically, and the lower end of the vertical rod of described cross supporting frame is fitted with a sliding sleeve G; Described sliding sleeve C is adjacent and is hinged with connecting rod E between the side Neva, and the middle part of described connecting rod E and described sliding sleeve G are hinged; Described sliding sleeve D is adjacent and is hinged with connecting rod F between the side Neva, and the middle part of described connecting rod F and described sliding sleeve G are hinged; Described connecting rod E is relative with described connecting rod F, and described outer watt radial symmetric is arranged.
Compared with prior art, the beneficial effect that had of radial telescopic type tire assembly drum of the present invention is:
Because in the prior art, the radial expansion motion of the Neva of tire assembly drum and outer watt, be by two groups of different sizes and drive with the hinged linkage of Neva and outer watt respectively and realize, exist the linkage number many, the deficiency that space big, structure inadequately compact of assembly drum between two groups of Nevas under the minimum of contraction state and outer watt.In the tire assembly drum of the present invention, be to drive Neva and the motion of outer watt of realization radial expansion simultaneously by one group of linkage that links with Neva, its stretching motion of outer watt is respectively to be driven down by the linkage that the Neva that is adjacent links to realize, therefore, tire assembly drum of the present invention compared with prior art, reduce one group and driven the outer watt of linkage of realizing stretching motion, not only alleviated complete machine weight, and make the assembly drum structure simpler, compact, magnification is bigger, and it is wider to be suitable for the tire building parameter area.In the tire assembly drum of the present invention, be actuated element with the leading screw, leading screw can be by driven by servomotor, and control is simple, and kinematic accuracy is higher.
