[0002] In today's rapidly developing automotive industry, wheel hubs, as a key component of vehicles, directly affect vehicle performance and safety through their machining precision and quality. Among these processes, the machining of valve bores is crucial, as the positional accuracy and machining quality of the valve bores are vital for tire air tightness and the vehicle's proper operation.

[0003] In existing wheel hub valve hole positioning drilling processes, the limited functionality of the worktable poses a significant challenge. Currently, most worktables can only horizontally place and fix the wheel hub before drilling. However, automotive wheel hubs come in various styles, and the valve hole positions differ, not all being horizontally aligned. This necessitates manual tilting of the wheel hub during actual machining to match the hole position. However, manual operation makes it difficult to precisely control the tilt angle and position, easily leading to deviations and inaccurate hole placement. This affects wheel hub quality, increases scrap rates, and causes numerous adverse effects on production. Therefore, we propose a wheel hub valve hole positioning drilling device to solve the aforementioned problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a hub valve hole positioning drilling device, including a base 1 and a worktable 2;

[0023] The base 1 has support seats 3 on both sides of its top. Each support seat 3 has a guide groove 4 inside, and a guide block 5 slides inside each guide groove 4. A connecting block 6 slides on each support seat 3. The guide blocks 5 are detachably connected to the connecting blocks 6 on the same side. The connecting blocks 6 are connected to the bottom sides of the worktable 2. The base 1 is connected to the worktable 2 via an adjustment assembly 7. The worktable 2 has a fixed plate 8 inside. A positioning shaft 9 is located at the center of the top of the fixed plate 8. The fixed plate 8 has multiple sliding grooves 10 inside, and multiple clamping blocks 11 slide inside each sliding groove 10. Each sliding groove 10 has a telescopic baffle 19, one end of which is connected to the clamping block 11. The fixed plate 8 is connected to the clamping block 11 via a drive assembly 12. The drive assembly 12 includes a drive disk 121 and a moving shaft 122. The drive disk 121 is rotatably mounted inside the fixed disk 8. The drive disk 121 has multiple sets of moving slots 13 inside. Multiple sets of moving blocks 14 are slidably mounted inside the fixed disk 8. Each set of moving blocks 14 has a moving shaft 122 adapted to the moving slot 13 at one end. The rotating rod 15 is rotatably mounted inside the worktable 2. One end of the rotating rod 15 rotates through the fixed disk 8 and connects to the bottom of the drive disk 121. The worktable 2 has an installation slot 16 inside. The installation slot 16 has a detachable motor for driving the rotating rod 15. Multiple sets of heat dissipation holes 17 are provided on both sides of the installation slot 16. The top left end of the worktable 2 has nozzles 18 at both ends. The two sets of nozzles 18 are connected to an external air supply system.

[0024] When in use, the center of the wheel hub is inserted into the positioning shaft 9 at the center of the fixed plate 8 at the top of the workbench 2. Then, the rotating rod 15 is driven by the motor to rotate. The rotating rod 15 drives the drive plate 121 to rotate, and the multiple sets of moving grooves 13 on the surface of the drive plate 121 rotate synchronously. The moving grooves 13 drive the moving shaft 122 to move synchronously. The moving shaft 122 drives the corresponding moving block 14 to slide inside the corresponding slide groove 10. At the same time, the telescopic baffle 19 inside the slide groove 10 extends and retracts synchronously. Then, the multiple sets of moving blocks 14 drive the clamping block 11 at the top to move synchronously. After the clamping block 11 contacts the edge of the wheel hub, the wheel hub is fixed.

[0025] The adjustment component 7 includes a mounting block 701, a semi-worm gear 702, and a worm 703. The two sets of support seats 3 are connected by the mounting block 701. The semi-worm gear 702 is installed in the middle of the mounting block 701. The bottom of the worktable 2 is rotatably provided with a worm 703 that meshes with the semi-worm gear 702. Both sets of support seats 3 are semi-circular. The bottom curvature of the connecting block 6 is adapted to the support seat 3.

[0026] Since the valve hole opening positions differ depending on the wheel hub model, the worm gear 703 is rotated by a motor. A dust cover can be fitted over the motor to prevent debris from entering. Because the worm gear 703 meshes with the worm wheel, the rotation of the worm gear 703 drives the worktable 2 to slide in the guide groove 4 inside the support base 3 via the connecting blocks 6 on both sides of the bottom and the guide block 5. This allows the angle of the worktable 2 to be adjusted, making it easier to open the valve hole at the wheel hub opening position. At the same time, after opening the valve hole, debris will remain on the surface of the worktable 2. Gas is sprayed out through the two sets of nozzles 18 on one side of the worktable 2 to clean the surface.

[0027] Working Principle: When using the hub valve hole positioning drilling device, the center of the hub is inserted into the positioning shaft 9 at the center of the fixed plate 8 on the top of the worktable 2. The rotating rod 15 is then driven by a motor to rotate, causing the drive plate 121 to rotate. Multiple sets of moving grooves 13 on the surface of the drive plate 121 rotate synchronously. These moving grooves 13 then drive the moving shaft 122 to move synchronously. The moving shaft 122 then drives the corresponding moving block 14 to slide inside the corresponding slide groove 10. Simultaneously, the telescopic baffle 19 inside the slide groove 10 extends and retracts synchronously. The multiple sets of moving blocks 14 then drive the top clamping block 11 to move synchronously. After the clamping block 11 contacts the edge of the hub, it performs the drilling operation. The valve hole positions vary depending on the wheel hub model. The worm gear 703 is driven to rotate by a motor. A dust cover can be fitted over the motor to prevent debris from entering. Since the worm gear 703 meshes with the worm wheel, its rotation causes the worktable 2 to slide through the guide block 5 in the guide groove 4 inside the support base 3 via the connecting blocks 6 on both sides of the bottom. This allows for adjustment of the worktable 2's angle, facilitating the drilling of the wheel hub opening. After drilling, any remaining debris on the worktable 2's surface is cleaned by air ejected from the two sets of nozzles 18 on one side of the worktable 2, thus completing a series of tasks. Content not described in detail in this specification is prior art known to those skilled in the art.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
