Description
Technical field
The invention belongs to tyre detacher, particularly the design and fabrication technology field of wherein tire lip disconnector, it is arranged on tyre detacher assistant, and moves with tyre detacher assistant.
Background technology
As everyone knows, use with the large old-fashioned tyre detacher shoveled when being removed from wheel rim by tire, first the large shovel 4 of use is separated tire lip, and this is shovel violence partition method greatly.Along with the development of Automobile Service technology, occur that some new separation tire lip tool and methods, these new tools and the object of method are that protection tire is not damaged when being separated tire lip on the market.Patent EP1607247A1 provides a kind of instrument being separated tire lip, and this instrument is arranged on tyre detacher assistant, with tire withdrawal plate, adopts rotary motion partition method to be separated tire lip.The while that rotary motion partition method and tire withdrawal plate being executed stressed to lower tire side wall, also rotate with the rotation of tire, when just having there is gap in the laminating position of tire lip and rim flange, gap is extended into before tool interior generation action makes tire withdrawal plate, thus make pressure act directly on tire lip, continue to rotate until tire mouth departs from rim flange.Rotary motion partition method belongs to and is separated gradually, and the effect of its protection tire is better than above-mentioned large shovel violence partition method.
But the instrument of the separation tire lip that patent EP1607247A1 provides also has two defects: one is that this structure directly makes little cylinder bear the antagonistic force of fork, and make the cylinder cap of little cylinder bear higher pair contact and the roll extrusion effect of fork, be easy to little cylinder is damaged, thus cause tool failures.Two is that this structure does not have special spacing part, two determining positions that the initial bit of tire withdrawal plate and protrusive position only rely on the cylinder cap of little cylinder to protract and bounce back, along with the wearing and tearing of little cylinder head, the initial bit of tire withdrawal plate and protrusive position become inaccurate, produce harmful effect to tearing tire open.
Summary of the invention
The invention provides a kind of tire lip disconnector be arranged on tyre detacher assistant, its technical scheme is as follows: the inside of the present invention and tire lip disconnector adopts one to take turning rolls as the mechanism of hinge, turning rolls combines with other part and realizes three objects, one is the rotary motion horizontal motion of small cylinder piston bar being changed into turning rolls, two is export rotational force to pass to fork and withdrawal plate, and three is the spacing of the spacing part of acceptance.
Turning rolls is provided with three hinge holes, three hinge holes press Triangle-Profile, and wherein the first hinge hole is provided with finger, and the second hinge hole installs the second roller through the second roller shaft, and the 3rd hinge hole installs the first roller through the first roller shaft.

Detailed description of the invention
As shown in Figure 4, spindle nose support 19 is arranged on tyre detacher assistant 22, and tyre detacher assistant 22 is connected with tyre detacher main frame 21.As shown in Figure 1, spindle nose support 19 is connected with little cylinder 20, and the piston rod of little cylinder 20 is threaded with fork-join head 18 through spindle nose support 19.Fork-join head 18 is hinged through guide plate jointed shaft 17 and guide plate 16, and guide plate 16 can slide along the guide groove of spindle nose support 19.Driving slot rolling is had in guide plate 16, slot rolling is driven to have two activation points namely to drive slot rolling upper end 16-2 and drive slot rolling lower end 16-1(to see Fig. 3), drive slot rolling from the horizontal by leaning angle, as shown in Figure 1, drive in slot rolling to be provided with in the second roller 15, second roller 15 and second roller shaft 14 is installed.Turning rolls 9 is hinge part, turning rolls 9 is provided with three hinge holes by Triangle-Profile, be respectively the first hinge hole 9-1, second hinge hole 9-2, 3rd hinge hole 9-3(is shown in Fig. 3), second hinge hole 9-2 of turning rolls 9 is connected with the other end of the second roller shaft 14, 3rd hinge hole 9-3 of turning rolls 9 is connected with the first roller shaft 13, the other end of the first roller shaft 13 is connected with the first roller 10, first roller 10 is arranged in the spacing slot rolling of positioning plate 11, spacing slot rolling has two restraining position and spacing slot rolling upper end 11-2 and spacing slot rolling lower end 11-1(to see Fig. 3), spacing slot rolling is also from the horizontal by leaning angle, as shown in Figure 1, spacing slot rolling direction is contrary with driving slot rolling direction.Positioning plate 11 is fixed on spindle nose support 19 side by hinged bolts 12.First hinge hole 9-1 of turning rolls 9 is connected with finger 8, and the other end of finger 8 is connected with fork 4, and fork 4 is hinged through fork jointed shaft 7 and spindle nose support 19.Fork 4 is connected with withdrawal plate axle 1, and withdrawal plate axle 1 and two tapered roller bearings 2 are arranged in withdrawal plate 3.Mechanism's protective cover 5 is fixed on spindle nose support 19, and fork head protector 6 is fixed on fork 4.
Principle of work: before using tire lip disconnector, withdrawal plate 3 is first made to return to initial position, as shown in Figure 1, the rodless cavity of little cylinder 20 is brought about the desired sensation, the piston rod of little cylinder 20 stretches out, and driving fork-join head 18 to move forward, fork-join head 18 drives guide plate 16 to move forward, and guide plate 16 slides along the guide groove of spindle nose support 19.Because the driving slot rolling of guide plate 16 is from the horizontal by leaning angle, therefore the second roller 15 when guide plate 16 moves forward, can be forced to move forward and scroll up, until drive the position of slot rolling upper end 16-2.Drive turning rolls 9 clickwise through the second roller shaft 14 when second roller 15 moves forward, turning rolls 9 drives the first roller 10 to roll along the spacing slot rolling of positioning plate 11 through the first roller shaft 13, and it is limited and stop that the first roller 10 arrives spacing slot rolling upper end 11-2.Meanwhile, turning rolls 9 drives fork 4 to rotate around fork jointed shaft 7 through finger 8, and fork 4 drives withdrawal plate 3 to swing, and returns to initial position.
As shown in Figure 5, in separation tire lip process, withdrawal plate 3 first contacts tire 23.As shown in Figure 6, withdrawal plate 3 presses down tire 23, gap is there is between tire 23 and wheel rim 24, at this moment in order to extend into the gap between tire 23 and wheel rim 24 before making withdrawal plate 3, the rod chamber of little cylinder 20 is brought about the desired sensation, the piston rod retraction of little cylinder 20, and move after driving fork-join head 18, fork-join head 18 moves after driving guide plate 16, moves and roll downwards when moving after guide plate 16 after forcing the second roller 15, until drive the position of slot rolling lower end 16-1.Drive turning rolls 9 left-hand revolution through the second roller shaft 14 when moving after the second roller 15, turning rolls 9 drives the first roller 10 to roll along the spacing slot rolling of positioning plate 11 through the first roller shaft 13, arrives spacing slot rolling lower end 11-1 limited and stop.Meanwhile, turning rolls 9 drives fork 4 to rotate around fork jointed shaft 7 through finger 8, and fork 4 drives withdrawal plate 3 to swing to position of protracting.As shown in Figure 7, before withdrawal plate 3, extend into the gap between tire 23 and wheel rim 24, continue to press down separation until the tire lip of tire 23 departs from wheel rim 24.
