Technical Field

[0001] The utility model relates to the technical field of wheel hubs, and more specifically, to a fixing tool for obliquely-positioned single-side drilling of valve holes. Background Art

[0002] A valve hole is provided on a wheel hub to correspond to a valve on an inflatable tire. The valve hole is usually drilled on the rim after the wheel hub is manufactured. The conventional fixing method is to vertically fix the wheel hub, but this processing is only applicable to the valve hole design with a vertical 90°, and the valve hole with an inclined design cannot use such a process for positioning and processing. Summary of the Utility Model

Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] As Figures 1 - 3 shown, an inclined single-side drilling valve hole fixing tooling includes a base plate 1. A support plate 3 is arranged on the base plate 1, and the included angle between the base plate 1 and the support plate 3 is 20 - 60 degrees. A limiting mechanism 13 is arranged at a position near the lower part of the upper part of the support plate 3. The limiting mechanism 13 and the support plate 3 are perpendicular to each other, and at least two limiting mechanisms 13 are provided. In this application, two limiting mechanisms 13 are provided, and the two limiting mechanisms 13 are symmetrically arranged on both sides of the midline of the support plate 3. The hub is placed on the support plate 3 to make the hub in an inclined state, and the limiting mechanism 13 supports the lower part of the hub. Since the two limiting mechanisms 13 are symmetrically arranged, the two limiting mechanisms 13 are in contact with the symmetric positions on the outer periphery of the hub, thereby completing the limitation of the hub.

[0017] This tooling further includes a mounting base 8, which is horizontally arranged. A lifting mechanism 9 and a profiling template 12 are mounted on the upper part of the mounting base 8. An opening 17 is provided in the middle position of the upper part of the support plate 3. The lifting mechanism 9 is drivingly connected to a lifting plate 10. The lifting plate 10 and the profiling template 12 pass through the opening 17. The front end of the lifting plate 10 is connected to a pressing block 11, and the pressing block 11 is located above the profiling template 12. The profiling template 12 supports the rim of the wheel hub. The lifting mechanism 9 controls the lifting plate 10 to descend, thereby driving the pressing block 11 to move downward. The pressing block 11 and the profiling template 12 cooperate to clamp the rim. After the wheel hub is fixed, it is prepared for the subsequent machining of the inclined valve holes.

[0018] The limiting mechanism 13 includes a mounting block 14. An oblong hole 15 is provided in the mounting block 14. A limiting rod 16 is connected to the mounting block 14. A hole is provided in the support plate 3, and a fixing bolt passes through the oblong hole 15 and the hole in the support plate 3. The provision of the oblong hole 15 enables the installation position of the mounting block 14 to be adjusted, thereby adjusting the distance between the two limiting rods 16, and effective support can be provided for wheel hubs of different diameters.

[0019] The lifting mechanism 9 is a cylinder, a hydraulic cylinder or an electric push rod.

[0020] A rotating seat one 2 is arranged on the upper part of the base plate 1. One end of the support plate 3 is hinged to the rotating seat one 2. The lower part of the other end of the support plate 3 is connected to a rotating seat two 4. An adjusting screw rod 5 is hinged to the rotating seat two 4. A sliding groove 18 is provided in the base plate 1. The support seat is slidably arranged in the sliding groove 18. The rotating seat two 4 passes through the support seat 6. An adjusting nut 7 is rotatably arranged on the support seat 6, and the adjusting nut 7 is threadedly connected to the adjusting screw rod 5. By rotating the adjusting nut 7, the adjusting screw rod 5 is driven to lift, thereby changing the inclination angle of the support plate 3, so that the inclination of the wheel hub on the support plate 3 is changed to meet the machining of valve holes with different inclinations. During the lifting process of the adjusting screw rod 5, the support seat 6 will be driven to slide on the base plate 1.

[0021] Fixing blocks 19 are connected to both sides of the support seat 6. Mounting holes are provided in the fixing blocks 19. Corresponding to the positions below the fixing blocks 19 on the base plate 1, strip-shaped holes are provided. Fixing bolts pass through the mounting holes and the strip-shaped holes, thereby completing the fixation between the fixing blocks 19 and the base plate 1, and the support seat 6 can be prevented from sliding again after the inclination angle of the support plate 3 is adjusted.

[0022] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
