Description

Technical Field

[0001] The present invention relates to the field of tire fastening, and in particular to a secondary fastening auxiliary tooling for an inner tire of a vehicle. Background Art

[0002] Electric dump trucks used in mining require regular inspection and re-tightening of tire fasteners. Currently, the spacing between the inner and outer tires on the rear axle of mining trucks on the domestic market is narrow. This creates a shortage of working space for maintenance personnel in mining areas, making it difficult to install tools and perform fastener inspections and re-tightening. Removing the outer tire for re-tightening increases maintenance cycles, impacting vehicle availability.

[0003] Some products solve this problem by installing a rim spacer between the inner and outer tires, allowing the outer tire fasteners to tighten the tires uniformly. Other products reduce the number of fasteners on the inner and outer tires, increase the spacing between them, and design a special outer rim that allows tools to pass through the outer tire to tighten the inner tire's standard parts. Both solutions solve the tightening problem by reducing the number of tire fasteners. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a secondary fastening auxiliary tooling for the inner tire of a vehicle, which can complete the inspection and secondary fastening of the inner tire fasteners without reducing the number of inner and outer tire fasteners and without changing the distance between the inner and outer tires.

[0005] The present invention is achieved according to the following technical solutions:

[0006] In a first aspect, the present invention discloses a secondary fastening auxiliary tool for an inner tire of a vehicle, comprising:

[0007] A workpiece welding body is provided with a connecting member for connecting to the outer peripheral surface of the wheel hub between the inner and outer tires and a positioning member for positioning the position of the inner tire fastener;

[0008] A magnetic component is installed on the workpiece welding body. The magnetic component is adsorbed on the outer peripheral surface of the wheel hub to fix the workpiece welding body on the wheel hub.

[0009] In some embodiments, the workpiece welding body is in an overall arc-shaped structure, and its curvature is consistent with the outer peripheral surface of the wheel hub, so that the workpiece welding body can fit on the outer peripheral surface of the wheel hub.

[0010] In some embodiments, the connecting components of the workpiece welding body are as follows: a hook is provided at the top end of the workpiece welding body facing the outer peripheral surface of the hub, and the hook is hooked in a groove on the outer peripheral surface of the hub.

[0011] In some embodiments, the positioning component of the workpiece welding body is as follows: the workpiece welding body is evenly spaced on the entire surface facing away from the wheel hub, and the multiple slots correspond one-to-one to the inner tire fasteners to be fastened, and the position of the inner tire fastener can be accurately found according to the position of the slots.

[0012] In some embodiments, the workpiece welding body is arranged behind the wheel hub, and each of the slots is tilted upward to support the torque tool.

[0013] In some embodiments, a handle is fixed to the tail end of the workpiece welding body, and the secondary fastening tooling for the inner tire of the vehicle is lifted by the handle and inserted between the inner and outer tires.

[0014] In some embodiments, the magnetic attraction component is a magnetic seat. Rotating the magnetic seat switch turns on the magnetic seat to adsorb the secondary fastening tooling of the inner tire of the vehicle onto the wheel hub; rotating the magnetic seat switch turns off the magnetic seat to separate the secondary fastening tooling of the inner tire of the vehicle from the wheel hub.

[0015] In some embodiments, the magnetic component is connected to the tail end of the workpiece welding body through a connecting rod, an angle plate and a fastener.

[0016] In some embodiments, a reaming seat is provided on the tail end and the angle plate of the workpiece welding body, the angle plate is fixed together with the magnetic component by bolts, and the two ends of the connecting rod are connected to the corresponding reaming seats by bolts and nuts.

[0017] In a second aspect, the present invention discloses a secondary fastening method for a vehicle inner tire, which is implemented using the above-mentioned vehicle inner tire secondary fastening auxiliary tooling. The specific implementation method is as follows:

[0018] The operator holds the handle and hangs the secondary fastening auxiliary tooling on a groove on the outer surface of the wheel hub between the inner and outer tires for preliminary positioning;

[0019] The operator rotates the magnetic base switch to firmly attach the secondary tightening auxiliary tooling to the wheel hub. Then, the operator combines the sleeve and the extension rod and inserts them horizontally into the outer slot of the nearest workpiece weld body. The slot corresponds to the inner tire fastener to be tightened. The operator pushes the extension rod toward the inner wheel and rotates it at the same time until the sleeve is fully inserted into the standard part to be tightened.

[0020] The operator determines the angle of the extension rod by touch and installs the manual torque wrench to complete the torque setting operation;

[0021] After tightening the standard part corresponding to one slot, the operator places the torque tool into another slot to tighten the corresponding standard part;

[0022] After the operator has completed the tightening of the standard parts corresponding to the multiple slots on the workpiece weld body, the rotating wheel edge drives the hub to rotate, and the workpiece weld body is hung in another groove on the outer surface of the hub for preliminary positioning. The operator rotates the magnetic seat switch to firmly adsorb the secondary tightening auxiliary tooling on the hub, and completes the tightening of the standard parts corresponding to the multiple slots on the workpiece weld body using the fixed torque tool;

[0023] Repeat the above steps until all the standard parts on the inner tire are tightened.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] Currently, most drive axles in the industry address the secondary tightening of inner and outer tires by reducing the number and distribution of tire fasteners. This invention, however, can perform spot inspection and secondary tightening of inner tire fasteners without reducing the number of these fasteners or changing the spacing between the inner and outer tires. It also offers the advantages of low cost, easy assembly and disassembly, and convenient operation. It is also widely applicable and can be applied to most mining dump trucks.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0035] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0036] like Figure 1 、 Figure 2 、 Figure 3 The figure shows a secondary fastening auxiliary tooling for the inner tire of a vehicle, comprising a workpiece welding body 1 and a magnetic component 3. The workpiece welding body 1 is equipped with a connecting component for connecting to the outer circumference of the wheel hub between the inner and outer tires, and a positioning component for locating the position of the inner tire fastener. The magnetic component 3 is mounted on the workpiece welding body 1 and adsorbed onto the outer circumference of the wheel hub, securing the workpiece welding body 1 to the wheel hub. Based on the above features, the present invention can achieve positioning of the inner tire fastener of the wheel hub in a narrow space, assist in the installation of a torque setting tool, and provide support, thereby completing the fastening of standard parts in a narrow space.

[0037] A preferred embodiment of the above embodiment regarding the workpiece welding body is given below:

[0038] Continue to refer to Figure 1 、 Figure 2 、 Figure 3 As shown, the workpiece weld body 1 is an overall arc-shaped structure, and its curvature is consistent with the outer peripheral surface of the wheel hub, so that the workpiece weld body 1 can fit on the outer peripheral surface of the wheel hub.

[0039] The connecting parts of the workpiece welding body 1 are as follows: a hook 10 facing the outer peripheral surface of the hub is provided at the top end of the workpiece welding body 1, and the hook 10 is hooked in a groove 13 on the outer peripheral surface of the hub.

[0040] The positioning components of the workpiece weld body 1 are as follows: Multiple slots 4 are evenly spaced across the entire surface of the workpiece weld body 1 facing away from the wheel hub. These slots 4 correspond one-to-one with the inner tire fasteners to be tightened. The operator can accurately locate the inner tire fasteners based on the location of the slots 4 and complete the tightening operation. Due to the multiple slots 4, the vehicle inner tire secondary tightening auxiliary tooling can complete multiple tightening operations with each installation.

[0041] A further solution is to place the workpiece welding body 1 behind the wheel hub, and each of the slots 4 is tilted upward to support the wrench tool. Since the tilted slots 4 support the end of the torque tool away from the operator, the physical exertion during operation can be reduced.

[0042] Further solution: A handle 11 is fixed to the tail end of the workpiece welding body 1, and the operator can easily lift the secondary fastening auxiliary tooling for the inner tire of the vehicle with one hand and insert it between the inner and outer tires.

[0043] A preferred embodiment of the magnetic attraction component of the above embodiment is given below:

[0044] The magnetic component 3 is a magnetic seat. The operator rotates the magnetic seat switch to turn on the magnetic seat, and the secondary fastening auxiliary tooling of the inner tire of the vehicle is adsorbed on the wheel hub; the operator rotates the magnetic seat switch to turn off the magnetic seat, and the secondary fastening auxiliary tooling of the inner tire of the vehicle is separated from the wheel hub.

[0045] A further solution: A reaming seat is provided on the tail end of the workpiece weld body 1 and on the angle plate 12. The angle plate 12 is secured to the magnetic component 3 via bolts 5 and washers. The ends of the connecting rod 2 are connected to the corresponding reaming seats via bolts 5 and nuts 6. After the secondary tightening auxiliary fixture for the vehicle's inner tire is positioned on the wheel hub, the magnetic component 3 naturally adheres to the outer surface of the wheel hub due to the action of the connecting rod 2 and its own gravity.

[0046] Working process: The top of the workpiece welding body 1 has a hook-shaped structure designed to match the characteristics of the outer surface of the wheel hub. The overall curvature is consistent with the outer diameter of the wheel hub. The operator holds the handle 11 and can hang the secondary fastening auxiliary tooling on a groove 13 on the outer surface of the wheel hub between the inner and outer tires for preliminary positioning. The magnetic component 3 is connected to the tail of the workpiece welding body 1 through the connecting rod 2. The connecting rod 2 ensures that the magnetic surface of the magnetic component 3 is tightly fitted with the outer surface of the wheel hub under the action of its own gravity. The employee can firmly adsorb the secondary fastening auxiliary tooling on the wheel hub by rotating the magnetic seat switch. Then, the sleeve 9 is combined with the extension rod 7 and inserted horizontally into the outer slot 4 of the workpiece welding body 1 that is closest to it. The slot 4 corresponds one-to-one with the inner tire fastener to be fastened. Push the extension rod 7 toward the inner wheel and rotate it slightly until the sleeve 9 is fully inserted into the standard part to be fastened. The operator only needs one hand to complete the above operation without entering between the inner and outer tires, which solves the problems of insufficient operating space and difficult installation of torque tools. Afterwards, the operator can roughly judge the driving angle of the extension rod by touching it, and install the manual torque wrench 8 to complete the torque setting operation.

[0047] After tightening the standard parts corresponding to one slot 4, the operator places the torque tool into another slot 4 to tighten the corresponding standard parts; when the operator completes the tightening of the standard parts corresponding to multiple slots 4 on the workpiece welding body 1, the rotating wheel rim drives the wheel hub to rotate, and hangs the workpiece welding body 1 in another groove 13 on the outer surface of the hub for preliminary positioning. The operator rotates the magnetic seat switch to firmly adsorb the secondary tightening auxiliary tooling on the wheel hub, and completes the tightening of the standard parts corresponding to multiple slots on the workpiece welding body through the torque tool; repeat the above actions until all the standard parts in a circle on the inner tire are tightened.

[0048] The above-mentioned fastening method is further described below through a preferred embodiment.

[0049] In actual use, the inner tire has 48 fastening positions, one of which has a slot for the inner wheel inflation tube, which is used for the over-inflation tube. Therefore, the inner tire has 47 fastening positions. The outer surface of the wheel hub is provided with 8 grooves at intervals, and one groove can correspond to 6 standard parts. Therefore, 6 card slots are provided on the workpiece weld body, and the 6 card slots correspond to the 6 standard part installation positions. The secondary fastening is hung in the first groove, and the 6 standard parts are fastened by the fixed torque tool and the 6 card slots; then the secondary fastening is hung in the second groove, and the 6 standard parts are fastened by the fixed torque tool and the 6 card slots; and so on, the fastening of 47 standard parts in 8 grooves is completed.

[0050] It should be noted that the initial positioning between the secondary fastening tooling of the inner tire of the vehicle and the wheel hub, and the distribution of the outer slots of the secondary fastening tooling of the inner tire of the vehicle can be adjusted according to the design parameters of the wheel hub. Therefore, the present invention can be extended to the application in the secondary fastening operation process of the inner tire of the rear axle of most mining dump trucks.

[0051] In summary, most drive axles in the industry currently use a solution that reduces the number and distribution of tire fasteners to solve the problem of secondary fastening of the inner and outer tires. The present invention can complete the inspection and secondary fastening of the inner tire fasteners without reducing the number of inner and outer tire fasteners and without changing the spacing between the inner and outer tires. It can be promoted and applied to most mining dump trucks.

[0052] It should be noted that the use of a cantilevered mobile bracket to lift the torque tool between the inner and outer tires can replace the present invention to achieve a similar effect, but it is difficult to accurately find the location of the fastener and complete the installation of the tool. If necessary, it is necessary to use an endoscope or other equipment to observe the situation inside the tire; when adjusting the driving wheel angle to tighten other positions around the circumference, it is easy to remember the wrong tightening order, resulting in unnecessary repetitive work.

[0053] Therefore, compared with the above-mentioned alternatives, the present invention has the advantages of accurate positioning, low cost, small size and easy portability.

[0054] In the description provided herein, numerous specific details are described. However, it is understood that embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques are not shown in detail so as not to obscure the understanding of this description.

For example, in the above embodiments, those skilled in the art will be able to use them in combination based on the known technical solutions and the technical problems to be solved by this application.

[0056] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention.
