DETAILED DESCRIPTION

[0025] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0026] The wheel hub repairing device according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 5 As shown, the wheel hub repair device of the embodiment of the present application comprises a base plate 1, a moving mechanism 2, a working box 3 and a repair assembly 4, wherein the moving mechanism 2 is mounted on the bottom surface of the base plate 1. The working box 3 is mounted on the base plate 1, and the repair assembly 4 comprises a lifting mechanism 41, a protective cylinder 42, a development groove 43, an extension plate 44, a first driving mechanism 45, a rotating plate 46, a spraying pipe 47, a plurality of spraying heads 48 and a protective assembly 49, wherein the lifting mechanism 41 is slidably arranged on the working box 3.

[0028] It should be noted that more than two spraying pipes 47 can be installed on the rotating plate 46 as needed, and different spraying pipes 47 can spray different paint surfaces to meet the needs of spraying primer and protective paint.

[0029] The protective tube 42 is slidably connected to the working box 3 through the lifting mechanism 41, and the development groove 43 is provided in the protective tube 42. The extension plate 44 is installed on one end of the protective tube 42 through the development groove 43.

[0030] It should be noted that there are multiple extension plates 44, and the multiple extension plates 44 can correspond to wheels of different sizes. When repairing different wheel hubs, the extension plates 44 that match the sizes can be rotated to achieve the purpose of covering tires of different sizes.

[0031] The first driving mechanism 45 is installed in the protective tube 42 , and the rotating plate 46 is installed on the first driving mechanism 45 and movably disposed in the protective tube 42 .

[0032] It should be noted that the first driving mechanism 45 adopts a rotary motor, and the rotary motor can rotate forward and reverse, thereby driving the spray head 48 to spray the protective paint on the wheel hub comprehensively.

[0033] The spray pipe 47 is installed on the rotating plate 46 , a plurality of spray heads 48 are installed on the spray pipe 47 in a linear array distribution, and a protection component 49 is installed in the protection tube 42 .

[0034] Specifically, during actual use, the scratched wheel hub needs to be repaired, which requires cleaning and painting, and the tire needs to be protected during painting.

[0035] When it is necessary to protect the tire on the wheel hub, first select an extension disk 44 of appropriate caliber and install it on one end of the protective tube 42 through the opening groove 43, then move the substrate 1 through the moving mechanism 2, and then the substrate 1 drives the protective tube 42 to move to the side of the wheel hub to be repaired, and make the extension disk 44 at one end of the protective tube 42 and the wheel hub contact each other. After contact, the output end of the first driving mechanism 45 can be controlled to rotate by the control switch, so that the output end of the first driving mechanism 45 drives the rotating plate 46 to rotate. The rotation of the rotating plate 46 can drive the spray pipe 47 and multiple spray heads 48 to rotate. While the multiple spray heads 48 are rotating, the external pipeline provides the spray pipe 47 with spraying raw materials, and finally the spraying raw materials are sprayed by the multiple rotating spray heads 48, so that the wheel hub can be repaired by spraying paint.

[0036] In one embodiment of the present application, Figure 3 As shown, the extension disk 44 is installed in the development groove 43 through a clamping member, and the inner diameter of the extension disk 44 is smaller than the inner diameter of the protective tube 42.

[0037] It should be noted that, since the sizes of wheel hubs are not the same, when facing wheel hubs of different sizes, extension plates 44 of different sizes can be installed to protect the tire.

[0038] In one embodiment of the present application, Figure 4 As shown, the first driving mechanism 45 rotates forward or reversely at an angle of three hundred and sixty degrees respectively.

[0039] It should be noted that since the spray pipe 47 on the rotating plate 46 is connected by an external pipe, the raw material for spraying can be provided to the spray pipe 47. However, when the rotating plate 46 is rotated at a large angle, the external pipe will be entangled on the first driving mechanism 45, affecting normal use.

[0040] In one embodiment of the present application, Figure 2 As shown, the lifting mechanism 41 includes a lifting slot 411 , a moving block 412 , a transmission rod 413 and a second driving mechanism 414 , wherein the lifting slot 411 is opened on the working box 3 and is located at one side of the protective tube 42 .

[0041] It should be noted that the second drive mechanism 414 adopts a motor. When working, the output end of the second drive mechanism 414 is controlled by the control switch to rotate, so that the output end of the second drive mechanism 414 drives the transmission rod 413 to rotate, and the second drive mechanism 414 adopts a self-locking motor, which can keep the rotation angle continuously locked after rotation.

[0042] The moving block 412 is slidably disposed in the lifting slot 411 , and one end of the moving block 412 is connected to one end of the protective tube 42 .

[0043] It should be noted that the diameter of the moving block 412 is the same as that of the lifting slot 411 , so that the moving block 412 can only slide in the lifting slot 411 , thereby preventing the moving block 412 from rotating synchronously when the transmission rod 413 rotates.

[0044] The transmission rod 413 is rotatably disposed in the lifting slot 411 , and the transmission rod 413 is threadedly connected to the moving block 412 . The second driving mechanism 414 is installed on the top surface of the working box 3 , and the second driving mechanism 414 is connected to the transmission rod 413 .

[0045] Specifically, in actual use, it is necessary to adjust the position of the protective tube 42 according to the different diameters of the repair hub. During adjustment, the transmission rod 413 is driven to rotate by the output end of the second driving mechanism 414. Since the transmission rod 413 and the moving block 412 are threadedly connected, the moving block 412 will move when the transmission rod 413 rotates, and the movement of the moving block 412 will drive the protective tube 42 to move, so that the position of the protective tube 42 can be adjusted according to the diameter of the repair hub.

[0046] In one embodiment of the present application, Figure 3As shown, the protection assembly 49 includes a blowing mechanism 491, a delivery pipe 492, a blowing slot 493 and a plurality of blocking components 494, wherein the blowing mechanism 491 is mounted on the working box 3. One end of the delivery pipe 492 is mounted on the blowing end of the blowing mechanism 491, and the other end of the delivery pipe 492 is mounted on the protection tube 42. The blowing slot 493 is provided in the protection tube 42, and the blowing slots 493 are connected to each other. A plurality of blocking components 494 are arranged in a circumferential array in the protection tube 42.

[0047] It should be noted that the blowing mechanism 491 adopts a blower, which blows air into the blowing slot 493 through the delivery pipe 492 during operation.

[0048] In one embodiment of the present application, Figure 3 As shown, the delivery pipe 492 is a hose, and the delivery pipe 492 is greater than the length between the blowing mechanism 491 and the protective tube 42 .

[0049] It should be noted that when facing tires of different sizes, the height of the protective cylinder 42 needs to be adjusted. When the height of the protective cylinder 42 is adjusted, the hose can prevent the delivery tube 492 from affecting the movement of the protective cylinder 42.

[0050] In one embodiment of the present application, Figure 5 As shown, the sealing component 494 includes a blowing pipe 4941, a shrinking shell 4942, a wrapping cloth 4943 and an elastic band 4944, wherein the blowing pipe 4941 is installed in the protective tube 42, and the blowing pipe 4941 and the blowing groove 493 are connected to each other, the shrinking shell 4942 is rotatably installed on one end of the blowing pipe 4941, and one end of the blowing pipe 4941 is connected to the shrinking shell 4942.

[0051] It should be noted that the length of the blow pipe 4941 is greater than the length of the protective tube 42, so that when the protective tube 42 contacts the tire, one end of the blow pipe 4941 drives the contraction shell 4942 to enter the inside of the wheel hub, and the blow pipe 4941 can also adopt a telescopic tube, so that the blow pipe 4941 can be contracted as needed, and the spring is in a contracted state after contraction, and can be freely reset after use. The blow pipe 4941 with freely controllable length can further increase its adaptability.

[0052] The wrapping cloth 4943 is wrapped around the outer wall of the shrinking shell 4942 , and the wrapping cloth 4943 is in communication with the shrinking shell 4942 .

[0053] It should be noted that the shape of the shrink shell 4942 can be specifically adjusted according to the requirements of use, and is preferably rectangular or circular.

[0054] One end of the elastic band 4944 is mounted on the inner wall of the shrink shell 4942 , and the other end of the elastic band 4944 is connected to the wrapping cloth 4943 .

[0055] Specifically, during actual use, the tire on the wheel hub needs to be protected, and the brake parts on the wheel hub also need to be protected to prevent the protective paint from being sprayed on the brake parts and affecting the performance of the brake parts.

[0056] When the wheel hub is repaired by spray painting, the substrate 1 needs to be moved, and the movement of the substrate 1 will drive the protective tube 42 to move, and the movement of the protective tube 42 can drive the blowing tube 4941 to move, and finally the blowing tube 4941 drives the shrinking shell 4942 to enter the inner side of the wheel hub.

[0057] After the shrinking shell 4942 moves to the specified position, the operation of the blowing mechanism 491 is controlled so that the blowing mechanism 491 conveys the wind to the blowing slot 493 through the conveying pipe 492, and then flows from the blowing slot 493 to the blowing pipe 4941, and then flows from the blowing pipe 4941 into the shrinking shell 4942. The wind entering the shrinking shell 4942 increases the pressure inside the shrinking shell 4942, so that the wind blows up the wrapping cloth 4943 in the shrinking shell 4942, and then causes the wrapping cloth 4943 to bulge and extend in all directions, and finally the wrapping cloth 4943 extending in all directions protects the brake parts on the inner side of the wheel hub.

[0058] In one embodiment of the present application, Figure 4 As shown, the wrapping cloth 4943 is made of foldable elastic cloth, and the wrapping cloth 4943 has a certain degree of air permeability.

[0059] It should be noted that when repairing the wheel hub, it is necessary to continuously supply gas to the wrapping cloth 4943, and the gas is only for expanding the wrapping cloth 4943 to protect the memory of the wheel hub. A certain air permeability can allow the gas to flow out of the wrapping cloth 4943 after the inside of the wrapping cloth 4943 is full of gas. The elastic band 4944 can assist the contraction of the wrapping cloth 4943 to prevent the wrapping cloth 4943 from being still distributed everywhere after losing the blowing of gas, making it inconvenient to collect the wrapping cloth 4943.

[0060] In one embodiment of the present application, Figure 5 As shown, a damping ring is provided at the connection between the blowing pipe 4941 and the shrinking shell 4942 , and the damping ring is installed on the outer wall of the blowing pipe 4941 .

[0061] It should be noted that the damping ring is used to increase the friction between the blowing pipe 4941 and the shrinking shell 4942. When facing a wheel hub with different patterns, the angle of the shrinking shell 4942 can be adjusted so that the shrinking shell 4942 can smoothly enter the inside of the wheel hub. The damping ring increases the friction between the blowing pipe 4941 and the shrinking shell 4942, thereby improving the stability of the shrinking shell 4942 after rotation.

[0062] In summary, the wheel hub repair device of the embodiment of the present application, by providing a protective tube 42 and a wrapping cloth 4943, can effectively protect the tire and brake parts when repairing the wheel hub, prevent the protective paint from being sprayed onto these parts, thereby avoiding affecting their performance. In addition, the protective tube 42 and the wrapping cloth 4943 are easy to install and reusable, and have better environmental protection effects.
