Description
Technical field
The utility model belongs to tyre retreading technique field, is specifically related to a kind of tyre rebuilding balloon device.
Background technology
It is the main path of tire resource circulation utilization that junked tire is overhauled recycling, is also the major measure of junked tire decrement.Tyre rebuilding will be ground off with damaged part through special process processing, be changed new rubber combination, make worn tire be called a complete tire.But in refurbishment process, exist a series of problem, such as: the tire bead diameter contacting with chuck and the diameter of outer chuck also not exclusively equate, even if be all in addition tyres for passenger cars, the different brands tire that its different manufacturers is produced also has difference, thereby while causing installation, tire mouth and chuck are gapped, make the center of circle of tire and the center of circle bias of chuck.Tire after polishing is not the center of circle, but oval, can make the quick heel and toe wear of tire, damages axle bearing, even causes to blow out and affect safety.
The problem existing in order to solve prior art, people have proposed various solutions.For example, Chinese patent literature discloses a kind of shaping equipment and method [application number: CN200810138001.7] thereof of tire surface laminating machine, the present invention applies centripetal constraint and reset force to avoid occurring secter pat dislocation and locked problem to secter pat in the process of the outside spreading of assembly drum, assembly drum integral demounting and replacing problem are solved, improve the strength transmission between internal structure, but complicated structure, make the outside spreading of balloon by Compressed Gas, need to guarantee good sealing.
Utility model content
The problem that the utility model exists for prior art, provides one can realize self-centering, inflates simple, safe and reliable tyre rebuilding balloon device.
The technical solution of the utility model is:
Compared to the prior art, the utility model is for the feature of tyre rebuilding device, tyre rebuilding is divided into the support component of the first travel mechanism, the second travel mechanism and second travel mechanism's end with balloon device, drive the radial motion of the second travel mechanism by the axially-movable of the first travel mechanism, the first described travel mechanism comprises main shaft, is sheathed on the taper shaft of main shaft, and drives the driving mechanism of taper shaft axially-movable; Described the second travel mechanism comprises the radial axle coordinating with taper shaft inclined-plane, and radial axle is arranged between left dish and right ring flange.Based on such scheme, the utility model also improves as follows:
Fixing in order to realize, between left dish and right ring flange, be bolted.
Driving mechanism adopts cylinder, hydraulic cylinder or spiral travel mechanism, simple in structure, easy to operate.
Radial axle end is connected with expansion board, and arc iron sheet is equipped with in expansion board outside, for connecting adjacent expansion board.
Expansion board outside is surrounded by round rubber cover, has good retractility, the entirety of expansion board and radial axle composition is pushed back to original position, thereby make taper shaft be moved back into original position, for the techniques such as tire polishing, rubberizing, pressing provide pressure.
Main shaft is made up of cylinder axis and rotating shaft, and taper shaft is set on cylinder axis, and right ring flange is connected with rotation axle key, and rotation the tip of the axis connects motor reducer.
The right-hand member of right ring flange is connected to gas-flow closure ring, has air-filled pore and venthole on sealing ring, respectively external air inlet pipe and escape pipe.Due to fixing of gas-flow closure ring, when ring flange rotates, can not make gas main rotate and cause fault, and tracheae can rotate with the rotation of balloon, can not cause winding.
On right ring flange, have two passages that communicate with air-filled pore on sealing ring and venthole, respectively connect a tracheae, two described tracheaes are connected with arbitrary expansion board.
Two tracheaes adopt threeway to be connected with expansion board, and the gas that enters into tracheae enters expansion board by threeway, has air-filled pore on expansion board, and then realizes the aerification function of tire, and threeway connects the inflation rate of being convenient to improve tire.
Radial axle lower end is inclined-plane, is convenient to contact with the conical surface of taper shaft.
Technique effect of the present utility model is:
The utility model drives taper shaft axially to seesaw by travel mechanism, thereby drives the radial axle that lower end is inclined-plane to stretch out the self-centering that realizes tire simultaneously, simple in structure; And the gas passage structure that the utility model adopts is also fairly simple, can not cause because of the rotation of balloon the winding of tracheae, safe and reliable, easy to use.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described:
As shown in Figure 1, a kind of tyre rebuilding balloon device, comprises cylinder 1, main shaft 2, left dish 3, right ring flange 4, taper shaft 5, radial axle 6, expansion board 7, iron sheet ring 8, rubber sleeve 9, snap ring 10, gas-flow closure ring 11.Left dish 3 inside are provided with taper shaft 5, and taper shaft 5 is connected with main shaft 2.Radial axle 6 has eight (quantity can be determined according to left dish 3 and right ring flange 4 sizes), is evenly distributed in the groove that right ring flange 4 opens, and radial axle 6 cochains are connected to expansion board 7, and radial axle 6 lower ends are an inclined-plane, with the conical surface joint of taper shaft 5.Left dish 3 is bolted with right ring flange 4, and snap ring 10 is at the front end of main shaft 2, and cylinder 1 pulls taper shaft 5 to carry out axially-movable by snap ring 10, and then realizes the radial motion of radial axle 6, realizes the expansion function of balloon.Iron sheet ring 8 fragmented packets are on expansion board 7, and iron sheet ring 8 outsides are surrounded by rubber sleeve 9.When main shaft 2 protracts, entirety expansion board 7 and radial axle 6 being made up of the convergent force of rubber sleeve 9 own pushes back original position, thereby makes taper shaft 5 be moved back into original position.So just realize the contractile function of balloon.
Gas circuit is arranged as shown in Fig. 1,2,3,4,5, is connected to gas-flow closure ring 11 at right ring flange 4 right-hand member chains, and while guaranteeing that balloon rotates, inflation exhaust pipe device maintains static.On gas-flow closure ring 11, have three holes, 201,203 is through hole, respectively external air inlet pipe and escape pipe.202 is screwed hole, does not get through, and gas-flow closure ring 11 is bolted to fixture, plays the effect of fixing gas-flow closure ring 11, prevents its rotation.Air inlet pipe, escape pipe enter in groove 205 by through hole 201,203, in groove 204,206, rubber seal ring 207 are installed, and prevent gas leakage.Passage 301 on right ring flange 4 is connected respectively tracheae 401 with passage 306 and 402, two tracheaes of tracheae are received respectively in the threeway 403 of expansion board 7.Threeway 403 is closely connected with the hole 501 on expansion board 7, has passage 404 on expansion board 7, communicates with hole 501.So just make gas enter passage 404 from hole 501, realized the function of tyre inflating.Fixing due to gas-flow closure ring 11, right ring flange 4 rotates, and can not cause gas main to rotate and cause accident, and tracheae 401, tracheae 402 can rotate along with the rotation of balloon, can not cause winding.When completing after polishing or rubberizing, exhaust.When venting, gas can return on Yan Yuan road, and in actual mechanical process, main shaft 2 protracts, and rubber sleeve 9 shrinks, and balloon dwindles, and gas is just run away in the large gap by tire and rubber sleeve, and realization bleeds a tire.
