[0024] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] It should be noted that the terms "first," "second," etc. (if applicable) in the specification of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of utility models consistent with some aspects of this application.

[0026] As a key component of the automotive chassis system, wheels not only directly affect vehicle driving safety but also significantly impact the overall appearance quality of the vehicle. During wheel manufacturing, burr removal is a crucial step in ensuring product quality. The presence of burrs not only disrupts the smoothness of the wheel surface but can also lead to uneven paint film thickness, reduced adhesion, and even localized corrosion failure during subsequent painting processes, severely impacting the wheel's lifespan and aesthetics.

[0027] In related technologies, burr removal processes mainly rely on manual grinding, which suffers from drawbacks such as low efficiency, high labor intensity, and unstable processing accuracy. With the automotive industry's ever-increasing demands for production efficiency and quality control, manual grinding can no longer meet the needs of modern production lines. Therefore, there is an urgent need for an automated, multi-station wheel burr grinding device.

[0028] This invention provides a multi-station wheel burr grinding device, thereby improving the efficiency of wheel burr grinding. See also... Figure 1 , Figure 1 This utility model provides a front view of a multi-station wheel burr grinding device, combined with... Figure 2 The diagram shows a top view of a multi-station wheel burr grinding device. The device includes a first station 3, a second station 4, a third station 5, a fourth station 6, a main motor 1, and a rotary table 2. The output end of the main motor 1 is vertically upward and connected to the rotary table 2, driving the rotary table 2 to rotate. The rotary table 2 is a cube, with its four side walls corresponding to the first station 3, second station 4, third station 5, and fourth station 6. Any one of the four side walls is used to mount a wheel 27. The first station 3, second station 4, third station 5, and fourth station 6 are arranged circumferentially, with a 90° interval between adjacent stations. The first station 3 is used for loading and unloading the wheel 27; the second station 4 is used for grinding the burrs on the valve holes of the wheel 27; the third station 5 is used for grinding the burrs on the windows of the wheel 27; and the fourth station 6 is used for grinding the burrs on the bolt holes of the wheel 27.

[0029] The device provided by this utility model adopts a multi-station design, allowing the wheel 27 to complete all necessary burr grinding processes within a single device. This improves production efficiency and reduces the additional costs associated with dispersed processes. The rotary table 2 in the device is the core component of the entire system. Driven by the main motor 1, it can achieve precise 90° rotation, thereby sequentially bringing the wheel 27 into different stations. The rotation mechanism ensures that the wheel 27 can quickly switch between various stations without manual intervention, thus improving the degree of automation.

[0030] The cubic structure of the rotary table 2 provides a stable mounting platform for the four workstations. Furthermore, each workstation is optimized for a specific grinding task. For example, the second workstation 4 focuses on grinding burrs on valve holes, the third workstation 5 handles window burrs, and the fourth workstation 6 processes bolt hole burrs. This clear division of labor not only improves grinding accuracy but also ensures that every part receives thorough processing.

[0031] During operation, wheel 27 is first loaded and unloaded at the first station 3, and then passes through the other three stations in sequence for burr grinding of different parts. The entire process is controlled by the main motor 1 and the tilting servo motor 7 in coordination, ensuring the efficiency and consistency of the grinding.

[0032] In one possible implementation, any one of the second station 4, the third station 5, and the fourth station 6 includes a three-axis servo adjustment module. The three-axis servo adjustment module is used to drive the cutter head to move in order to grind the burrs on the wheel 27. The three-axis servo adjustment module includes a Y-axis motor 9, a Y-axis guide rail 10, a Y-axis worktable 11, an X-axis motor 12, an X-axis guide rail 13, an X-axis worktable 14, a Z-axis motor 15, a Z-axis guide rail 16, and a Z-axis worktable 17. The X-axis motor 12, the X-axis guide rail 13, and the X-axis worktable 14 are located on the Y-axis worktable 11, and the Z-axis motor 15, the Z-axis guide rail 16, and the Z-axis worktable 17 are located on the X-axis worktable 14.

[0033] Y-axis motor 9 is used to drive Y-axis worktable 11 to move along Y-axis guide rail 10 in a first direction, which is the vertical direction; X-axis motor 12 is used to drive X-axis worktable 14 to move along X-axis guide rail 13 in a second direction, which is perpendicular to the first direction and perpendicular to a third direction, which is perpendicular to the first direction and perpendicular to the side wall plane of the rotary table 2 corresponding to any workstation; Z-axis motor 15 is used to drive Z-axis worktable 17 to move along Z-axis guide rail 16 in a third direction.

[0034] Y-axis motor 9 drives Y-axis worktable 11 to move vertically (i.e., in the first direction) along Y-axis guide rail 10. This vertical movement adjusts the height of the cutting head to allow for grinding of burrs at different heights on the wheel 27. X-axis motor 12 drives X-axis worktable 14 to move horizontally (i.e., in the second direction) along X-axis guide rail 13. The second direction is perpendicular to both the first and third directions. This horizontal movement adjusts the cutting head's position in the radial direction of the wheel 27, allowing it to approach or move away from specific areas of the wheel 27. Z-axis motor 15 drives Z-axis worktable 17 to move in the third direction along Z-axis guide rail 16. This third direction is perpendicular to both the first and the sidewall plane of the rotary table 2, allowing the cutting head to be adjusted in the axial direction of the wheel 27, thus enabling the grinding of burrs at different depths or angles on the wheel 27.

[0035] The three-axis servo adjustment module enables precise movement of the cutter head in three mutually perpendicular directions. Its high-precision adjustment capability allows the cutter head to flexibly adapt to the burr grinding needs of different parts of the wheel 27, effectively handling burrs around valve holes, windows, and bolt holes. Through precise control of the servo motor, the three-axis servo adjustment module can automatically adjust the position and movement trajectory of the cutter head according to a preset program, achieving automated burr grinding, reducing manual intervention, and improving production efficiency and processing quality. The module's design takes into account the burr distribution characteristics and grinding requirements of different parts of the wheel 27, and can quickly adjust the position and angle of the cutter head according to different processing tasks, exhibiting strong adaptability and meeting the burr grinding needs of various types of wheels 27.

[0036] In one possible implementation, the Z-axis worktable 17 of the second station 4 includes a second servo motor. A second turntable is mounted on the output end of the second servo motor. A valve hole tapered end mill 25 and a valve hole grinding head 26 are respectively mounted on both sides of the second turntable. The valve hole tapered end mill 25 and the valve hole grinding head 26 are symmetrically distributed in a straight line. The second servo motor is used to drive the second turntable to rotate so that at least one of the valve hole tapered end mill 25 and the valve hole grinding head 26 is used to process the wheel 27. The valve hole tapered end mill 25 is used to file and mill the burrs on the edge of the valve hole of the wheel 27. The valve hole grinding head 26 is used to grind and smooth the burr sharp corner residue.

[0037] This milling cutter is designed to effectively remove burrs, preparing it for subsequent grinding processes. The valve hole grinding head 26 further smooths out any remaining sharp corners of the burrs, ensuring the smoothness and evenness of the valve hole edges, thereby improving the overall quality of the wheel 27. Comprehensive burr treatment of the wheel 27's valve holes can be achieved in a single station, from initial burr removal to final surface grinding, all efficiently completed at the second station 4. This improves processing efficiency and ensures consistent processing quality. Precise control of the second servo motor allows for flexible switching between the two tools to meet the processing needs of different stages.

[0038] In one possible implementation, the Z-axis worktable 17 of the third station 5 includes a third servo motor, and a window tapered milling cutter 24 is mounted on the output end of the third servo motor. The window tapered milling cutter 24 is used for milling the window burrs of the wheel 27.

[0039] The third servo motor precisely controls the rotational speed and position of the window tapered milling cutter 24, enabling the cutter to perform precise milling operations along the edge of the wheel 27 window. This improves the efficiency of burr removal and ensures consistent machining quality. Furthermore, the shape and material of the window tapered milling cutter 24 are optimized to adapt to wheel 27 windows of different sizes and shapes, thus achieving efficient burr removal on various wheel 27 models. Through this design, the third station 5 can flexibly handle various window burr problems of wheels 27, further enhancing the adaptability and practicality of the entire device.

[0040] In one possible implementation, the Z-axis worktable 17 of the fourth station 6 includes a fourth servo motor 18, and a fourth turntable 19 is mounted on the output end of the fourth servo motor 18. A bolt hole tapered end mill 23 and a bolt hole grinding head 21 are respectively mounted on both sides of the fourth turntable 19. The bolt hole tapered end mill 23 and the bolt hole grinding head 21 are symmetrically distributed in a straight line. The fourth servo motor 18 is used to drive the fourth turntable 19 to rotate so that at least one of the bolt hole tapered end mill 23 and the bolt hole grinding head 21 is used to process the wheel 27. The bolt hole tapered end mill 23 is used to file and mill the burrs on the edge of the bolt hole of the wheel 27. The bolt hole grinding head 21 is used to grind the burrs and sharp corner residues.

[0041] Specifically, the bolt hole tapered end mill 23 is mainly used to file and mill the burrs on the edge of the bolt holes of the wheel 27, preparing for the subsequent grinding process. The bolt hole grinding head 21 is used to further grind away any remaining sharp corners of the burrs, ensuring the smoothness and evenness of the bolt hole edges, thereby improving the overall quality of the wheel 27. Comprehensive burr treatment of the wheel 27 bolt holes can be achieved in one station, from initial burr removal to final surface grinding, all efficiently completed at the fourth station 6. This improves processing efficiency and ensures consistent processing quality. Through the precise control of the fourth servo motor 18, the two tools can be flexibly switched to meet the processing needs of different stages. Optionally, this invention does not limit the driving method of the bolt hole tapered end mill 23 and the bolt hole grinding head 21. For example, the bolt hole grinding head 21 is driven by the first grinding servo motor 20, and the bolt hole tapered end mill 23 is driven by the second grinding servo motor 22.

[0042] In one possible implementation, any one of the four side walls of the rotary table includes a tilting shaft. The tilting shaft includes a tilting servo motor 7 and a tilting table 8. The tilting servo motor 7 drives the plane of the tilting table 8 to rotate along the rotation axis of the tilting servo motor 7. The rotation axis of the tilting servo motor 7 is parallel to the plane of the side wall on which the tilting servo motor 7 is mounted. The tilting table 8 is used to mount the wheel 27. Each station is equipped with a tilting shaft, allowing the wheel 27 to be processed at different angles.

[0043] The cutting heads in the second station 4, third station 5, and fourth station 6 mentioned in this embodiment are merely illustrative examples; cutting heads with other functions are also applicable. Furthermore, the four stations mentioned in this embodiment are only examples; more or fewer stations are all within the protection scope of this embodiment.

[0044] In summary, the technical solution provided by this utility model features a multi-station design that allows wheels to complete all processes—loading and unloading, valve hole burr grinding, window burr grinding, and bolt hole burr grinding—within a single device. This reduces process changeover time and manual intervention, improving production efficiency. Automated grinding is achieved by using a main motor to drive the rotary table and a tilting servo motor to adjust the wheel mounting angle. The introduction of a three-axis servo adjustment module further enhances automation, enabling the cutter head to move precisely in three directions to adapt to the burr grinding needs of different parts. The three-axis servo adjustment module allows for precise movement of the cutter head in three mutually perpendicular directions, ensuring thorough and consistent burr removal. The tilting shaft design allows wheels to be processed at different angles, adapting to the burr treatment needs of different parts. This device can handle various types of wheels, with different stations specifically designed for different parts of the wheel, exhibiting strong adaptability. The rotary table adopts a cubic structure, with four stations arranged circumferentially and adjacent stations spaced 90° apart, resulting in a compact layout, small footprint, and suitability for limited workshop production environments. Centralized placement of grinding tools and a simplified design facilitate maintenance and replacement, reducing maintenance costs. Reduced manual intervention and equipment footprint lower production costs. Simultaneously, an efficient production process shortens production cycles and improves overall production efficiency.
