Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing technology, specifically to an integrated equipment for precision grinding and polishing of aluminum alloy wheel hubs. Background Technology

[0002] Grinding and polishing are key processes for improving the surface quality of aluminum alloy wheels. Grinding uses tools such as grinding wheels to gradually remove the oxide layer, scratches and casting defects on the surface of the wheel, refining the surface roughness and laying the foundation for subsequent polishing. Polishing uses polishing wheels with polishing paste to further reduce the surface roughness through mechanical friction, giving the wheel a mirror-like shine, while also enhancing its corrosion resistance and aesthetics. The combination of the two processes allows the wheel to have both durability and visual appeal.

[0003] Existing technologies often have the following problems when used:

[0004] The grinding and polishing processes of aluminum alloy wheels are usually set up separately. The transfer of wheels between different equipment requires additional time and space, resulting in low overall processing efficiency. In addition, the fixed adjustment flexibility of the grinding and polishing equipment for aluminum alloy wheels is poor, making it difficult to adapt to the grinding and polishing processing needs of wheels of different sizes, which makes the equipment for grinding and polishing aluminum alloy wheels less versatile. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides an integrated precision grinding and polishing equipment for aluminum alloy wheels. This equipment effectively solves the problems of low overall processing efficiency caused by the separate grinding and polishing processes in existing technologies, as well as the poor flexibility and versatility of the grinding and polishing equipment, making it difficult to adapt to the processing needs of wheels of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an integrated precision grinding and polishing equipment for aluminum alloy wheel hubs, comprising: a base, the base having a hollow structure, a support frame fixedly connected to the upper surface of the base, and an integrated processing component fixedly connected to the top of the support frame;

[0008] The integrated processing component includes a guide rail fixedly connected to the top of the support frame, an electric slide block slidably mounted on the guide rail, a support slide rail fixedly connected to the lower end face of the electric slide block, an electric slider slidably connected to the inner side of the support slide rail, a concave frame fixedly connected to the lower end face of the electric slider, and a grinding and polishing component fixedly mounted at the bottom end of the concave frame.

[0009] A hub fixing assembly is fixedly installed on the inner bottom surface of the base.

[0010] Furthermore, the grinding and polishing component includes two electric push rods fixedly installed at the bottom end of the concave frame. The telescopic ends of the two electric push rods are each fixedly equipped with a high-speed motor, and the output ends of the two high-speed motors are respectively fixedly connected to a grinding wheel and a polishing wheel.

[0011] Furthermore, the hub fixing assembly includes a dual-axis motor fixedly installed on the inner bottom surface of the base. Both output ends of the dual-axis motor are fixedly connected to ball screws via couplings. The threads on the two ball screws have opposite helical directions. The outer peripheral walls of the two ball screws are threaded with linear sliders. The upper end faces of the two linear sliders are fixedly connected to T-shaped rods. The top ends of the two T-shaped rods are fixedly connected to arc-shaped clamps.

[0012] Furthermore, two strip-shaped sliding holes are provided at the top of the base, and the T-shaped rod slides in conjunction with the top of the base through the strip-shaped sliding holes.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 3 An integrated precision grinding and polishing equipment for aluminum alloy wheel hubs includes: a base 1, which has a hollow structure; a support frame 2 is fixedly connected to the upper surface of the base 1; an integrated processing component is fixedly connected to the top of the support frame 2; the integrated processing component includes a guide rail 3 fixedly connected to the top of the support frame 2; an electric slide block 4 is slidably mounted on the guide rail 3; a support slide rail 5 is fixedly connected to the lower surface of the electric slide block 4; an electric slider 6 is slidably connected to the inner side of the support slide rail 5; and a concave frame 7 is fixedly connected to the lower surface of the electric slider 6.

[0026] Specifically, the guide rail 3 is set along the horizontal X-axis direction, and the electric slide block 4 can move linearly along the guide rail 3 in the X-axis direction; the support slide rail 5 is fixed to the lower end face of the electric slide block 4 along the horizontal Y-axis direction, and the electric slider 6 can move linearly along the support slide rail 5 in the Y-axis direction. Through the linkage between the X-axis and the Y-axis, the grinding wheel 10 and the polishing wheel 11 can cover all the processing areas of the hub surface.

[0027] A grinding and polishing component is fixedly installed at the bottom of the concave frame 7. The grinding and polishing component includes two electric push rods 8 fixedly installed at the bottom of the concave frame 7. The electric push rods 8 are RM-SLA-08-30-1 linear servo push rods. A high-speed motor 9 is fixedly installed at the telescopic end of each of the two electric push rods 8. The high-speed motor 9 is a KBL2838 high-speed brushless DC motor. A limit slide rod 17 is fixedly connected to the outer wall of the high-speed motor 9 along its axis. A through hole is opened at the bottom of the concave frame 7, and the limit slide rod 17 slides with the concave frame 7 through the through hole. The two high-speed motors 9 are respectively fixedly connected to the output ends of the grinding wheel 10 and the polishing wheel 11. The grinding wheel 10 is made of brown corundum abrasive, with a diameter of 150mm, a grit size of 80 mesh, and a maximum speed of 3000r / min. It is suitable for removing the oxide layer and casting defects of 0.1-0.3mm thickness on the surface of the wheel hub. The polishing wheel 11 is made of wool wheel, with a diameter of 120mm and a maximum speed of 2500r / min. When used with alumina polishing paste, it can reduce the surface roughness of the wheel hub to below Ra0.05μm.

[0028] Specifically, if the aluminum alloy wheel hub requires grinding, the grinding wheel 10 can be driven to move downward by controlling the corresponding electric push rod 8, and the polishing wheel 11 can be driven to move upward by controlling the electric push rod 8 corresponding to the polishing wheel 11. The grinding wheel 10 can then be driven to rotate rapidly by the high-speed motor 9 to grind the aluminum alloy wheel hub.

[0029] Specifically, the electric slide 4, electric slider 6, electric push rod 8, and high-speed motor 9 are all coupled to a control circuit with an external power supply. The control circuit can control the movement of the electric slide 4 and electric slider 6. The control circuit uses a PLC controller (model S7-200SMART). The grinding / polishing path parameters are preset through the touch screen. The control circuit logic is as follows: After the grinding process is triggered, the electric push rod 8 drives the grinding wheel 10 to descend to the contact hub surface. At the same time, the high-speed motor 9 starts to 2000 r / min, and the electric slide 4 and electric slider 6 move according to the preset path. After grinding is completed, the grinding wheel 10 automatically rises, and the electric slide 4 and electric slider 6 drive the polishing wheel 11 to move to the processing start point. The polishing wheel 11 starts according to the same logic, realizing the automatic switching between the grinding and polishing processes.

[0030] Specifically, when the electric push rod 8 drives the high-speed motor 9 and the grinding wheel 10 or polishing wheel 11 to move up and down, the limiting slide rod 17 can slide relative to the concave frame 7 to maintain the up and down movement and operation stability of the high-speed motor 9.

[0031] By controlling the electric slide block 4 to slide along the guide rail 3 and simultaneously controlling the electric slider 6 to slide along the support slide rail 5, the grinding wheel 10 or polishing wheel 11 is adjusted to be directly above the area to be processed on the wheel hub. According to the grinding or polishing requirements of the aluminum alloy wheel hub, the extension and retraction of the telescopic ends of the two electric push rods 8 are controlled to make the grinding wheel 10 or polishing wheel 11 contact the wheel hub and grind or polish the wheel hub. This can realize the integrated grinding and polishing processing of the aluminum alloy wheel hub, effectively improving the overall processing efficiency of the aluminum alloy wheel hub.

[0032] A hub fixing assembly is fixedly installed on the inner bottom surface of the base 1. The hub fixing assembly includes a dual-axis motor 12 fixedly installed on the inner bottom surface of the base 1. The dual-axis motor 12 is a JGB37-520 dual-axis DC geared motor. The two output ends of the dual-axis motor 12 are fixedly connected to ball screws 13 through couplings. The threads on the two ball screws 13 have opposite helical directions. The outer peripheral walls of the two ball screws 13 are threaded with linear sliders 18. The upper end faces of the two linear sliders 18 are fixedly connected with T-shaped rods 14. The top of the base 1 has two strip-shaped sliding holes 16. The T-shaped rods 14 slide with the top of the base 1 through the strip-shaped sliding holes 16. The top of the two T-shaped rods 14 are fixedly connected with arc-shaped clamps 15. The arc-shaped clamps 15 are made of elastic stainless steel, and the outer surface of the arc-shaped clamps 15 is fixedly connected with a buffer pad.

[0033] Specifically, the ends of the two ball screws 13 away from the dual-axis motor 12 are fixed to the bearing seats on the inner side wall of the base 1 by deep groove ball bearings (model 6204). The bearing seats are rigidly connected to the inner bottom surface of the base 1 by bolts to ensure the coaxiality and stability of the ball screws 13 when rotating.

[0034] Specifically, when driving the two T-shaped rods 14 to move in opposite directions, the T-shaped rods 14 can slide relative to the top of the base 1 through the strip-shaped sliding hole 16 to ensure the linearity and stability of the movement of the T-shaped rods 14, the linear slider 18 and the arc-shaped clamping plate 15.

[0035] Specifically, the arc-shaped clamp 15 is made of elastic stainless steel. When the arc-shaped clamp 15 contacts the outer ring of the aluminum alloy wheel hub, the two ends of the arc-shaped clamp 15 first adhere to the wheel hub. As the arc-shaped clamp 15 continues to move closer to the wheel hub, it can cause the arc-shaped clamp 15 to expand outward and completely adhere to the aluminum alloy wheel hub, thus achieving full fixation of the aluminum alloy wheel hub. The arc-shaped clamp 15 is 2mm thick, with an arc radius ranging from 50-200mm and a maximum elastic deformation displacement of 10mm, making it suitable for aluminum alloy wheel hubs with diameters of 12-24 inches. The buffer pad is made of thick nitrile rubber with a Shore hardness of 60±5HA, which avoids indentation during clamping and ensures the quality of wheel hub processing.

[0036] The two ball screws 13 are driven to rotate by the dual-axis motor 12, so that the two linear sliders 18 can move in opposite directions along the axial direction of the ball screws 13. Then, the two arc-shaped clamps 15 can be driven to move in opposite directions by the two T-shaped rods 14 until the arc-shaped clamps 15 are completely pressed against the outer ring of the wheel hub, so as to fully fix the aluminum alloy wheel hubs of different sizes and improve the versatility of the aluminum alloy wheel hub grinding and polishing equipment.

[0037] The working principle of this utility model is as follows:

[0038] When processing aluminum alloy wheels, the wheel hub is first fixed at the center of the upper surface of the base 1. The electric slide block 4 is controlled to slide along the guide rail 3, and the electric slider 6 is controlled to slide along the support slide rail 5 to adjust the grinding wheel 10 or polishing wheel 11 to be directly above the area to be processed on the wheel hub. According to the grinding or polishing requirements of the aluminum alloy wheel hub, the extension and retraction of the telescopic ends of the two electric push rods 8 are controlled to make the grinding wheel 10 or polishing wheel 11 contact the wheel hub and grind or polish the wheel hub, so as to realize the integrated grinding and polishing processing of the aluminum alloy wheel hub.

[0039] When the aluminum alloy wheel hub is fixed to the upper surface of the base 1, the dual-axis motor 12 is first started. The dual-axis motor 12 drives the two ball screws 13 to rotate, so that the two linear sliders 18 can move in opposite directions along the axial direction of the ball screws 13. Then, the two T-shaped rods 14 can drive the two arc-shaped clamps 15 to move in opposite directions until the arc-shaped clamps 15 are completely pressed against the outer ring of the wheel hub, so as to fully fix the aluminum alloy wheel hubs of different sizes.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
