Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel hub manufacturing technology, and in particular to an adaptive brush burr device. Background Technology

[0002] After machining aluminum alloy wheels, the burrs remaining on the machined edges directly affect the product's appearance and corrosion resistance. Existing technologies typically employ a combination of deburring tools and high-speed rotating brushes. For example, patent document CN220296675U proposes an adaptive brush deburring device with a dust removal function, which integrates a brush bristle unit, a dust suction hood, and a blowing nozzle into the brush disc, effectively solving the problems of dust pollution and brush self-cleaning. However, this solution has significant drawbacks: the diverse wheel shapes necessitate custom-shaped brushes for different wheel types. In actual production, the wide variety of brush types not only significantly increases manufacturing and management costs but also requires frequent brush replacements during wheel type changes, resulting in long equipment downtime, low changeover efficiency, and severely restricting production flexibility and equipment utilization.

[0003] Therefore, developing an adaptive brush burr device for practical production is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a novel brush burr device that can adapt to the shape of the wheel hub. Through structural innovation, it achieves dynamic adjustment of the brush shape, eliminating the cost and time loss of changing shapes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An adaptive brush burr removal device includes several coaxially arranged annular discs. The lower end of each annular disc is provided with bristles for cleaning wheel hub burrs. The several annular discs are respectively arranged for different parts of the wheel hub surface to be cleaned, and adjacent annular discs are axially floatingly connected.

[0006] Preferably, adjacent annular disks are provided with corresponding sliding grooves and sliding keys, the sliding keys are axially slidingly engaged with the sliding grooves, and the bottom of the sliding grooves is provided with limit stops corresponding to the sliding keys.

[0007] Preferably, a synchronous transmission structure is provided between adjacent annular disks. The transmission structure consists of a flat key and a keyway correspondingly opened on the adjacent annular disks. The flat key and the keyway are arranged along the axial direction of the annular disks, and the flat key and the keyway are in clearance fit. Alternatively, the transmission structure consists of a toothed structure correspondingly opened on the adjacent annular disks. The toothed structure is arranged along the circumference of the annular disks, and the adjacent annular disks are driven by meshing through the toothed structure.

[0008] Preferably, the brush burr device further includes a top plate that floats and connects to the annular discs, and the top plate is floatably connected to each annular disc via a telescopic cylinder.

[0009] Preferably, each annular disc is connected to the top disc via three circumferentially distributed telescopic cylinders.

[0010] Preferably, conductive fibers are embedded in the brush bristles, and the conductive fibers are connected to a control circuit that controls the movement of the telescopic cylinder for controlling the downward height of the annular disc. The beneficial effects of this utility model are as follows: Based on the concentric annular disk design with axial floating connection, the height gradient of the brush bristles can be adjusted according to the curved surface contour of the wheel hub, overcoming the defect of traditional brushes that require customized modification due to wheel shape differences. A single device can accurately fit the processing edge of any shaped wheel hub, eliminating blind spots in burr treatment and ensuring edge smoothness and uniformity of anti-corrosion coating. When changing wheel shapes, brush replacement is completely eliminated, improving the efficiency of shape change and avoiding the customization, storage, and management costs of multi-specification brushes. The conductive fiber embedded in the brush bristles, combined with the closed-loop control circuit, realizes automatic positioning and stopping the machine the moment the brush bristles contact the wheel hub, avoiding the risk of overpressure damage. The floating stroke is constrained by the sliding key-sliding groove limiting structure, and the keyway / tooth synchronous transmission design ensures the axial freedom of each annular disk while maintaining the stability of torque transmission.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figure 1-3As shown, an adaptive brush burr removal device includes several coaxially arranged annular discs 10. The lower end of each annular disc 10 is provided with brush bristles 11 for cleaning wheel hub burrs. The several annular discs 10 are respectively arranged for different parts of the surface of the wheel hub to be cleaned, and adjacent annular discs 10 are axially floatingly connected so that the brush bristles 11 can adaptively conform to the surface of the wheel hub to be cleaned, thereby meeting the burr removal needs of different specific wheel shapes.

[0018] In use, the annular disc 10, connected to a rotating power source, drives the bristles 11 to rotate circumferentially, performing deburring operations on the surface of the wheel hub to be cleaned. The axial height of the annular disc 10 can be adjusted according to the wheel hub contour to achieve a tight fit between the bristles 11 and the curved surface of the wheel hub, eliminating blind spots in deburring and improving the smoothness of the processed edges and the consistency of corrosion resistance. At the same time, this invention has a certain degree of versatility, meeting the deburring needs of different wheel types, significantly reducing the manufacturing and management costs of the brushes, and eliminating the need for brush replacement during wheel type changes, reducing equipment downtime and improving changeover efficiency.

[0019] Preferably, an axial limiting structure is provided between adjacent annular disks 10 to limit the axial floating stroke between them and prevent them from disengaging. Specifically, adjacent annular disks 10 are provided with corresponding sliding grooves 12 and sliding keys 13. The sliding key 13 slides axially with the sliding groove 12, and a limit stop 14 is provided at the bottom of the sliding groove 12 corresponding to the sliding key 13, serving as a limiting structure for the relative displacement of adjacent annular disks 10. In use, the axial positioning height of adjacent annular disks 10 is adjusted by the sliding engagement of the sliding groove 12 and the sliding key 13. When the sliding key 13 slides within the sliding groove 12 to the limit stop 14, it abuts against the limit stop 14, preventing the sliding key 13 from moving further, thereby limiting the floating stroke of adjacent annular disks 10, preventing the annular disks 10 from disengaging, and ensuring structural stability.

[0020] A transmission structure is provided between adjacent annular disks 10 to enable synchronous rotation of each annular disk 10. The transmission structure may be a flat key 15 and a keyway 16 correspondingly formed on adjacent annular disks 10. The flat key 15 and keyway 16 are arranged axially along the annular disk 10, and the flat key 15 and keyway 16 are clearance-fitted, allowing a certain degree of axial freedom between adjacent annular disks 10. Torque transmission is achieved without affecting the floating connection between adjacent annular disks 10, ensuring the synchronicity and uniformity of the brush cleaning action.

[0021] Preferably, the transmission structure can also be a toothed structure correspondingly formed on adjacent annular disks 10, the toothed structure being arranged circumferentially along the annular disks 10, and adjacent annular disks 10 being driven by meshing through the toothed structure.

[0022] Preferably, the deburring device further includes a top plate 20 that is floatingly connected to the annular discs 10. Specifically, the top plate 20 is floatingly connected to each annular disc 10 via telescopic cylinders 21. By adjusting the lifting height of the telescopic cylinders 21 with different pitch circles, a gradient adjustment between the annular discs 10 is achieved, thereby adapting to the deburring operation of wheel hubs with different shapes. In use, the telescopic cylinders 21 are connected to a high-pressure air source through a rotary joint to obtain the telescopic adjustment power. The rotational power drives the top plate 20 to rotate, causing the bristles 11 to rotate circumferentially, performing deburring operations on the wheel hub to be cleaned. This embodiment achieves gradient surface adaptation by independently adjusting the lifting height of the telescopic cylinders 21 corresponding to each annular disc 10, resulting in a simple structure and high positioning accuracy.

[0023] Preferably, each annular disk 10 is connected to the top disk 20 by three circumferentially distributed telescopic cylinders 21, thereby reducing the number of telescopic cylinders 21 used while ensuring connection stability.

[0024] Preferably, conductive fibers 112 are embedded in the bristles 11. These conductive fibers 112 are connected to a control circuit that controls the movement of the telescopic cylinder 21, used for controlling the downward height of the annular disc 10. In use, the telescopic cylinder 21 pushes the annular disc 10 downwards, and the bristles 11 gradually approach the surface of the wheel hub. When the conductive fibers 112 in the bristles 11 contact the aluminum alloy surface of the wheel hub, the circuit is activated and a signal is triggered. The control circuit then stops the corresponding telescopic cylinder 21, achieving automatic height positioning of the bristles 11. The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
