Abstract
The utility model discloses a tire locking mechanism for a tire disassembly and assembly machine. In a screw rod combined body, multistage equidistant annular pitches are arranged at the upper part of a screw; an annular groove is formed between two adjacent pitches; and multi-line stepped threads are formed at the lower part of the screw. A positioning cone is arranged on the screw in a sleeving manner; and a magnetic opening is cushioned and embedded in the annular groove. A trapezoidal nut is mounted below a tire positioning disk at the upper part of a speed reducing device and is in threaded connection with the multi-line stepped threads; a worm shaft is connected with a ring flange through a flat key; and a gland is mounted at the shaft end. The ring flange is fixed with an outer cylinder by a screw. A movable inner sleeve is embedded in an inner hole of the outer sleeve; the trapezoidal nut and the flat key are embedded into the movable inner cylinder; and the tire positioning disk is integrally connected with the movable inner cylinder through screws. The tire locking mechanism has the advantages of reasonable structure, long lead of the multi-line stepped threads, quick screwing-in speed, favorable rigidity, high strength, stable and reliable performances, high work efficiency, easiness for operation, small size, light weight and low construction cost.
Description
Technical field:
The utility model belongs to tyre removing and replacing machine, particularly the design of its tire catch gear and manufacturing technology field.
Background technology:
One of major part of catch gear is screw mandrel.At present, the screw mandrel of tire catch gear all adopts single-start thread both at home and abroad.The locking of domestic employing fast nut: namely establish a mechanism on the nut body, when with holding when tight, nut can directly be inserted in without rotating, and is placed near the dowel disc; The tooth form of tripping-gear back nut embeds in the screw flight, screws nut and can carry out locking operation.Its advantage is the locking speed; Its shortcoming is that the tooth form of embedding is more shallow, loose, when bearing large load lock operation, the possibility of inefficacy is arranged.External single-start thread screw mandrel, its locking power derives from the miniature motor that is contained in top, uses self storage battery power supply.Its advantage is, novel structure is convenient to use, and its shortcoming is that volume is large, Heavy Weight, and needs often charging, and operability is bad, and cost is high, is difficult to promote.
Summary of the invention:
The purpose of this utility model is that a kind of tire catch gear of tyre removing and replacing machine is provided.
The utility model is achieved by the following technical solution.
For existing tire catch gear, mainly be the single threaded defective of screw mandrel wherein, a kind of multi-thread Acme thread screw mandrel and respective accessory thereof are provided, consist of the screw mandrel fabricate block.So-called multiple-screw thread is by the formed screw thread of two or more helix line that axially is equally spaced.The screw mandrel fabricate block is made of screw mandrel, magnetic force open washer and location cone.Screw mandrel top is equidistant multi-stage annular joint, joint and internode looping groove, and the screw mandrel bottom is multi-thread Acme thread, there is interior hex slot the screw mandrel upper surface.The location cone is sleeved on the screw mandrel, and the magnetic force open washer is enclosed within the annular groove on the screw mandrel.Screw mandrel fabricate block and speed reduction gearing form the tire catch gear.Trapezoidal nut with the multi-thread Acme thread coupling of screw mandrel fabricate block is housed below the speed reduction gearing upper tire dowel disc.Multi-thread Acme thread is connected with trapezoidal nut during tire locking operation.
Speed reduction gearing: reductor is contained in the tyre removing and replacing machine box house, and its mouth is that worm-wheel shaft stretches out casing vertically upward, below the speed reduction gearing upper tire dowel disc, the trapezoidal nut with multi-thread Acme thread coupling is housed, the two screwed connection.Flange is connected with worm-wheel shaft with flat key, and axle head is equipped with gland.Flange and urceolus are fixed by screw.Movable inner core is loaded in the endoporus of urceolus, and in trapezoidal nut and the flat key embedding activity inner core, tyre positioning disk links into an integrated entity with screw and movable inner core.
Using method of the present utility model is that the dress tire: the tire according to different size is enclosed within the magnetic force open washer in the annular groove of appropriate location, screw mandrel top.Tire is placed on the tyre positioning disk, and rotary screw makes multi-thread Acme thread and trapezoidal nut screwed connection.At this moment locate cone and make the tire automatic centering.When the locking tire the lower conical surface of location cone is contacted with the wheel rim endoporus, the upper surface contacts with the magnetic force open washer.Insert with manual or pneumatic hex spanner in the hex-shaped recess of screw mandrel upper surface, rotating spanner locking tire is finished dress tire process.Tear tire open: tear open the tire operating process with the dress tire opposite.
Whole tyre removing and replacing machine, except a kind of tire catch gear of the utility model narration, the structure of remainder is unchanged, and using method is unchanged.Its advantage is, rational in infrastructure, screw mandrel adopts multi-thread Acme thread helical pitch large, can screw in fast, and Acme thread good rigidly intensity is high, the safeguard work reliability.Stable and reliable for performance, easily operation, volume is little, and is lightweight, and cost is low.
Description of drawings
Below in conjunction with accompanying drawing planform of the present utility model and connection mode thereof are further specified.
Fig. 1 is the utility model structural representation.
Fig. 2 is screw mandrel composite unit structure schematic diagram.
Fig. 3 is triple-thread screw left-handed twist schematic diagram.
The 1-screw mandrel, the 2-annular groove, 3-magnetic force open washer, 4-locates cone, the multi-thread Acme thread of 5-, 6-tyre positioning disk, 7-trapezoidal nut, the movable inner core of 8-, 9-urceolus, 10-flange, 11-worm-wheel shaft, 12-reductor.
The specific embodiment
The utility model is comprised of screw mandrel fabricate block and speed reduction gearing.
The screw mandrel fabricate block is made of screw mandrel 1, magnetic force open washer 3 and location cone 4.Screw mandrel 1 top has multistage equidistant ring joint, looping groove 2 between joint and the joint.Screw mandrel 1 bottom is multi-thread Acme thread 5, and location cone 4 is sleeved on the screw mandrel 1, and magnetic force open washer 3 is enclosed within the annular groove 2 on the screw mandrel.There is interior hex slot screw mandrel 1 upper surface.Screw mandrel fabricate block and speed reduction gearing consist of the utility model.Be equipped with below the speed reduction gearing top, tyre positioning disk 6 with the screw mandrel fabricate block in the trapezoidal nut 7 of multi-thread Acme thread 5 couplings.Multi-thread Acme thread 5 and trapezoidal nut 7 are by screwed connection.Speed reduction gearing: reductor 12 is installed in the tyre removing and replacing machine box house, and worm-wheel shaft 11 stretches out casing, and flange 10 usefulness flat keys are connected with worm-wheel shaft 11, and shaft end has gland.Flange 10 and urceolus 9 are fixed by screw.Movable inner core 8 is loaded in the endoporus of urceolus 9,8 li of trapezoidal nut 7 and flat key embedding activity inner cores, and tyre positioning disk 6 usefulness screws and movable inner core 8 link into an integrated entity.
