[0018] The following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, those of ordinary skill in the art can recognize that, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the drawings and description are illustrative in nature and are not used to limit the protection scope of the claims.

[0019] Embodiment 1:

[0020] As Figures 1 to 4 Collectively shown, the multi - purpose tooling for hub processing and fixing includes a clamping plate 2. On the upper surface of one end of the clamping plate 2, a first limiting part 3 is installed, and on the lower surface of the other end of the clamping plate 2, a second limiting part 4 is installed. A threaded hole 9 is provided at the center of the clamping plate 2, and a fixing bolt 5 is installed through the threaded hole 9. The end of the screw rod of the fixing bolt 5 is fixedly connected to the clamping plate 2 through a fastening nut 6. The heights of the first limiting part 3 and the second limiting part 4 are respectively equal to the thickness of the hub 7 to be clamped. The beneficial effect of the present utility model is as follows: Place the hub 7 to be processed on the fixed disk 1. Determine to choose the first limiting part 3 to contact the fixed disk 1 according to the thickness of the hub 7. Pass the fixing bolt 5 through the bottom of the fixed disk 1, and the end of the fixing bolt 5 is fixedly connected to the clamping plate 2. After installing the clamping plate 2, rotate the clamping plate 2 by 90° to provide an avoidance space for the installation of the hub 7. Place the hub 7 on the fixed disk 1, rotate the clamping plate 2 by 90° so that it presses on the upper surface of the hub 7. At this time, tighten the fastening bolt and the fastening nut 6 to firmly fix the hub 7 on the fixed disk 1, and then process the hub 7. When it is necessary to process hubs 7 with different thicknesses, just remove the fixing bolt 5, flip the clamping plate 2 so that the second limiting part 4 contacts the fixed disk 1, and repeat the above operations. The present utility model can clamp hubs 7 with two thicknesses by flipping the clamping plate 2, without replacing other clamping tooling, which is convenient to install, improves the processing efficiency and saves costs.

[0021] As Figure 1As shown in the figure, the first limiting part 3 and the second limiting part 4 are cylinders with different diameters. The two cylinders are respectively welded on both sides of the clamping plate 2, and the diameter of the cylinder is equal to the thickness of the corresponding hub 7 to be clamped. When the first limiting part 3 and the second limiting part 4 are cylinders, they form a line contact with the hub 7, and the requirement for the flatness of the surface of the hub 7 is low. The welding fixing method is time-saving and labor-saving. The diameters of the two cylinders are determined according to the thicknesses of two common hubs 7. In this way, when switching between hubs 7 with two thicknesses in the same workshop, it is very convenient, and only the clamping plate 2 needs to be flipped.

[0022] As Figure 2 shown in the figure, a plurality of threaded mounting holes are evenly distributed on the fixed disc 1. The fastening nut 6 passes through from the bottom of the fixed disc 1 and is connected to the clamping plate 2 above the fixed disc 1. Each threaded mounting hole is provided with a clamping plate 2, and the hub 7 is clamped and fixed from multiple directions, making the fixing of the hub 7 more stable.

[0023] As Figure 2 shown in the figure, there are four threaded mounting holes evenly distributed. Preferably, four threaded mounting holes are provided, and a clamping plate 2 is provided every 90°. The hub 7 is fixed from four directions.

[0024] Embodiment 2:

[0025] This embodiment is basically the same as Embodiment 1, and the difference lies in:

[0026] As Figure 5 shown in the figure, the first limiting part 3 and the second limiting part 4 are rectangular blocks, and the rectangular blocks are detachably installed on both sides of the clamping plate 2. The thickness of the rectangular block is equal to the thickness of the corresponding hub 7 to be clamped. The rectangular blocks are detachably installed on both sides of the clamping plate 2. In this way, different thicknesses of the first limiting part 3 and the second limiting part 4 can be selected and replaced according to the thickness of the hub 7, and the replacement is detachable. In this way, only the first limiting part 3 and the second limiting part 4 with different thicknesses need to be prepared. The versatility is stronger.

[0027] As Figure 5 shown in the figure, stepped holes are respectively provided on the first limiting part 3 and the second limiting part 4. The screws 8 pass through the stepped holes and respectively fix and install the first limiting part 3 and the second limiting part 4 on the clamping plate 2. The heads of the screws 8 are flush with the surface of the clamping plate 2. The screws 8 are relatively common fixing parts. Of course, other fixing parts can also be used, as long as the first limiting part 3 and the second limiting part 4 are detachably installed on the clamping plate 2. The stepped holes can hide the screws 8 in the first limiting part 3 and the second limiting part 4 and do not protrude to contact the fixed disc 1, ensuring the firmness of the fixing of the hub 7.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0029] Only some exemplary embodiments of the present utility model have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as a limitation to the scope of protection of the claims of the present utility model.
