Technical Field
[0001] This utility model relates to the technical field of wheel hub processing, specifically a burr removal device for wheel hub processing. Background Technology
[0002] A wheel hub is a cylindrical metal component inside a car tire that supports the tire around an axle. In simple terms, it's the part of the wheel where the axle is mounted, and it's an important component connecting the brake drum, wheel disc, and half-shaft.
[0003] To ensure structural strength, car wheel rims are made of metal. After being manufactured, metal car wheel rims typically have burrs on their outer surface, a common feature of metal workpieces. Since the outer circumference of the wheel rim is in direct contact with the rubber tire, these burrs need to be thoroughly removed. However, current deburring devices have limitations in terms of the size of the wheel rims they can hold, making it inconvenient to secure wheel rims with significant size differences.

[0022] The following is a reference to the appendix. Figures 1-6 The preferred embodiments of this utility model are described below. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.
[0023] This utility model proposes a rotary burr removal device for wheel hub processing. Before use, a pair of clamping plates 11 are in the position with the greatest relative distance, slider one 8 is in the position with the greatest distance from the vertical plate 2, and slider two 6 is in the highest position. Figure 1As shown, when using this device, the hub 3 to be deburred is hung on the positioning cylinder 12 through the center hole. The hub 2 is pushed inward so that its inner side is in contact with the vertical plate 2. A knob is turned, which drives the lead screw 16 to rotate. The lead screw 16 drives a pair of sliders 17 to slide towards each other along the inner side of the straight groove plate 3. The pair of sliders 17 drive the corresponding clamping plates 11 to slide towards each other through the corresponding L-shaped rods 4. When the opposite side of the pair of clamping plates 11 is in contact with the hub 2, the knob is stopped. Screw one end of the fastening bolt 13 into the positioning cylinder 12. After the annular baffle of the fastening bolt 13 is tightly fitted against the hub 3, it provides axial limitation to prevent the hub 3 from shifting. Then tighten a pair of clamping plates 11 to achieve the purpose of fixing the hub. It can stably clamp hubs 3 of different diameters and has a wide range of applications. Select a suitable cutting tool 15, insert the tool holder into the tool cylinder 14, and tighten a pair of positioning bolts to secure the cutting tool 15 in the tool cylinder 14. Start the motor 9. The motor 9 drives the lead screw 10 to rotate. Motor 0 drives slider 8 to slide along the straight groove plate towards the vertical plate 2. Slider 8 drives cutter 15 to slide towards the hub 3 via the straight groove plate 2. When cutter 15 slides to the appropriate position, motor 9 is turned off, and the lateral position of cutter 15 is adjusted (i.e., to match the thickness of hub 3). Motor 5 is started, and motor 5 drives lead screw 7 to rotate. Lead screw 7 drives slider 6 to slide down along the straight groove plate 2. Slider 6 drives cutter 15 to slide down via cutter cylinder 14. When cutter 15 is in contact with the position of hub 3 to be deburred, motor 5 is turned off, and the height of cutter 15 is adjusted via the straight groove plate 2 (i.e., to match the diameter of hub 3). Motor 1 is started, and motor 1 drives hub 3 to rotate along cutter 15 via straight groove plate 3, achieving the purpose of deburring hub 3. After the burrs are removed, motor 1 is turned off, cutter 15 is returned to the initial position, and the polished hub 3 is removed by turning the knob in the opposite direction. This device is convenient for processing hubs of different models.
