[0001] The utility model belongs to the technical field of wheel hub punching, and particularly relates to a punching tool for a large plate of an automobile wheel hub. Background Art

[0002] The automobile wheel hub specifically refers to the structure that supports the inner side of the automobile tire, which plays a vital role. During the automobile wheel hub processing, it is necessary to drill holes in the automobile wheel hub. Before drilling, the automobile wheel hub needs to be fixed by a drilling jig to prevent the automobile wheel hub from shifting and affecting the accuracy of drilling.

[0003] In the prior art, the punching device is generally fixed manually, for example, a threaded rod drives a fixing block to slide and fix it, and then it needs to be manually disassembled when disassembling, which not only wastes time, but also wastes labor.

[0004] In the prior art, there are also methods for fixing by electrical components, such as publication number CN217749481U, which discloses an automobile wheel hub drilling jig, which is convenient for fixing wheels of different models, thereby completing the drilling operation.

[0005] However, the cost of setting up multiple sets of electric telescopic rods is not only high, but also the vibration generated when drilling holes and the vibration force acting on the electric telescopic rods can easily cause damage, making subsequent repairs time-consuming and labor-intensive.

[0006] To this end, we proposed a car wheel hub large plate punching tool, which can not only fix and process different types of wheel hub large plates, but also has low cost, does not require manual disassembly, and is also convenient for subsequent maintenance. Utility Model Content

[0007] The purpose of the present invention is to provide a punching tool for automobile wheel hub discs, which can not only perform fixed processing on wheel hub discs of different models, but also has low cost, does not require manual disassembly, and is convenient for subsequent maintenance.

A first gear 5 is provided on the fixed assembly. An arc-shaped slider 6 is provided inside the annular groove 4. A rotating ring 7 is installed on one side of the arc-shaped slider 6. A first meshing tooth 8 is provided on the top of the rotating ring 7. The first meshing tooth 8 meshes with the first gear 5. A second meshing tooth 9 is provided on the outer side of the rotating ring 7.

[0032] A second rotating assembly is arranged on the top of the chassis 1 , and a second gear 10 is arranged on the second rotating assembly. The second gear 10 meshes with the second meshing teeth 9 .

[0033] Its working principle is: place the wheel hub disk on the fixed disk 2, and then drive the second gear 10 to rotate through the second rotating component, the second gear 10 drives the second meshing tooth 9 to rotate the rotating ring 7, when the rotating ring 7 rotates, the first meshing tooth 8 rotates, the second meshing tooth 9 drives the first gear 5 to rotate, and the first gear 5 drives the fixed component to fix the wheel hub disk, so that wheel hubs of different diameters can be fixed.

[0034] The arc-shaped slide block 6 matches the annular groove 4 , so that the arc-shaped slide block 6 can rotate inside the annular groove 4 .

[0035] like Figure 3 As shown, two groups of electric telescopic rods 11 are arranged on the top of the chassis 1, a hollow shell 12 is installed on the top of the electric telescopic rod 11, a first threaded rod 13 and a third motor driving the first threaded rod 13 to rotate are arranged inside the hollow shell 12, a first threaded sleeve 14 is sleeved on the first threaded rod 13, a connecting block is arranged at the bottom of the first threaded sleeve 14, a fourth motor 15 is arranged at the bottom of the connecting block, and a drilling rod 16 is installed at the output end of the fourth motor 15.

[0036] The distance between the drilling rod 16 and the wheel hub disk can be adjusted by the electric telescopic rod 11, and then the third motor drives the first threaded rod 13 so that the first threaded sleeve 14 drives the connecting block to move the drilling rod 16 to the desired drilling position for drilling.

[0037] In order to ensure that the drilling rod 16 can move, a second slide groove is opened at the bottom of the hollow shell 12, and a connecting block is slidably arranged inside the second slide groove. When the threaded sleeve moves, the connecting block is driven to move inside the second slide groove, thereby enabling the drilling rod 16 to move.

[0038] At the same time, the second slide groove matches the connecting block, so that the connecting block can move smoothly inside the second slide groove.

[0039] like Figure 4As shown, the fixing assembly includes a second threaded rod 17 arranged inside the first slide groove 3, a second threaded sleeve 18 is sleeved on the second threaded rod 17, an arc-shaped fixing block 19 is installed on the top of the second threaded sleeve 18, and one end of the second threaded rod 17 passes through the fixing plate 2 and is connected to the first gear 5. When the first gear 5 rotates, it will drive the second threaded rod 17 to rotate, and the second threaded rod 17 drives the second threaded sleeve 18 to make the arc-shaped fixing block 19 fix the wheel hub disc.

[0040] The second threaded sleeve 18 matches the first sliding groove 3 , so that the second threaded sleeve 18 can move smoothly inside the first sliding groove 3 .

[0041] At the same time, a rubber pad is provided on the arc-shaped fixing block 19, which can prevent the wheel hub disc from being damaged when fixing. At the same time, the friction force of the rubber pad is relatively large, which prevents sliding when fixing.

[0044] It should be noted that a fixing rod is provided at the center of the fixing plate 2. Since the center of the wheel hub plate also has a fixing hole, when the wheel hub plate is installed, the fixing rod is inserted into the fixing hole for positioning to prevent movement during drilling.

[0045] The working principle of the utility model is as follows: firstly, the wheel hub disk is placed on the fixed disk 2, and the second motor 21 drives the second rotating shaft to rotate the second gear 10, and the second gear 10 drives the second meshing tooth 9 to rotate the rotating ring 7, and when the rotating ring 7 rotates, the first meshing tooth 8 rotates, and the second meshing tooth 9 drives the first gear 5 to rotate, and when the first gear 5 rotates, it drives the second threaded rod 17 to rotate, and the second threaded rod 17 drives the second threaded sleeve 18 to make the arc-shaped fixing block 19 fix the wheel hub disk, so as to adapt to different types of wheel hubs, and the distance between the drilling rod 16 and the wheel hub disk can be adjusted by the electric telescopic rod 11, and then the third motor drives the first threaded rod 13 to make the first threaded sleeve 14 drive the connecting block to move the drilling rod 16 to the position where the hole is to be drilled for drilling, and a hole is completed. Afterwards, the first motor 20 drives the first rotating shaft to rotate the fixed disk 2, so that the positions of different drilling holes can be adjusted, thereby completing the drilling operation of the wheel hub disk. When performing the disassembly operation, it is only necessary to drive the second rotating shaft through the second motor 21 to rotate the second gear 10 in the opposite direction, and the second gear 10 drives the second meshing tooth 9 to rotate the rotating ring 7. When the rotating ring 7 rotates, the first meshing tooth 8 rotates, and the second meshing tooth 9 drives the first gear 5 to rotate.
