[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding device for carbon fiber reinforced composite materials. Background Technology

[0002] Carbon fiber reinforced composites, with their superior properties such as high strength and lightweight, are widely used in aerospace, automotive manufacturing, and sporting goods. Grinding, as a crucial process after composite material processing and molding, directly affects its surface quality and subsequent assembly performance. The structural design, functional configuration, and operational flexibility of the grinding equipment play a decisive role in grinding efficiency and quality. With the continuous expansion of composite material applications, higher demands are being placed on the multifunctionality, adaptability, and efficiency of grinding equipment.

[0003] However, existing grinding tools for carbon fiber reinforced composite materials have shortcomings: Firstly, their functions are relatively limited, with most grinding devices designed only for one scenario—grinding plates or inner diameters of pipes. To grind different types of workpieces, multiple sets of specialized equipment are required, resulting in high equipment purchase costs and occupying a large amount of production space. Furthermore, frequent equipment changes are not only cumbersome but also easily reduce production efficiency. Secondly, existing grinding devices have deficiencies in grinding uniformity and precision control, leading to uneven grinding force and poor surface flatness, making it difficult to meet high-quality processing requirements. Moreover, the lack of flexible height adjustment makes it difficult to adapt to grinding workpieces of different sizes, failing to fully meet diverse production needs and limiting the efficiency and quality improvement of composite material processing. Summary of the Invention

[0004] To address the above problems, this application provides a carbon fiber reinforced composite material grinding device, including a transmission unit and a grinding unit. The transmission unit drives the grinding unit to reciprocate along a straight line. The grinding unit includes a grinding support frame, a grinding driver, a transmission rod, and a grinding wheel. The output end of the grinding driver is connected to the transmission rod, and the grinding wheel is installed at the end of the transmission rod. The grinding driver is detachably mounted on the grinding support frame, so that the axis of the transmission rod can be selectively perpendicular or parallel to the direction of travel of the transmission unit.

[0005] In one embodiment, the grinding support frame is provided with a height adjustment unit, the height adjustment unit includes a height adjustment screw and a height adjustment plate that is threadedly engaged with it, an adjustment handle is fixedly provided at the top end of the height adjustment screw, the height adjustment plate is placed in the grinding support frame, and the grinding driver is detachably mounted on the height adjustment plate.

[0006] In one embodiment, the transmission unit includes a transmission driver, a driving transmission wheel, a conveyor belt, a driven transmission wheel, and a guide rail. A slider is disposed on the guide rail, the grinding unit is fixedly disposed on the slider, and the conveyor belt is connected to the slider.

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0022] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] like Figure 1 , 2 As shown in Figure 3, a carbon fiber reinforced composite material grinding device includes a transmission unit 1 and a grinding unit 2, wherein the transmission unit 1 drives the grinding unit 2 to reciprocate along a straight line.

[0024] The grinding unit 2 includes a grinding support frame 21, a grinding driver 22, a transmission rod 23 and a grinding wheel 24. The output end of the grinding driver 22 is connected to the transmission rod 23, and the grinding wheel 24 is installed at the end of the transmission rod 23.

[0025] The grinding driver 22 is detachably mounted on the grinding support frame 21, so that the axis of the transmission rod 23 can be selectively perpendicular or parallel to the travel direction of the transmission unit 1.

[0026] Specifically, the grinding driver 22 is a servo motor, and the transmission unit 1 drives the grinding unit 2 to reciprocate along a straight line. The output end of the grinding driver 22 is connected to the transmission rod 23, and the grinding wheel 24 is mounted at the end of the transmission rod 23. The grinding driver 22 is detachably mounted on the grinding support frame 21 so that the axis of the transmission rod 23 can be perpendicular or parallel to the direction of travel of the transmission unit 1. Figure 1 As shown, when grinding the board material, the grinding driver 22 is mounted on the grinding support frame 21 with the axis of the transmission rod 23 perpendicular to the travel direction of the transmission unit 1. The transmission unit 1 drives the grinding unit 2 to move reciprocally in a straight line, while the grinding driver 22 drives the transmission rod 23 to rotate, thereby causing the grinding wheel 24 to rotate and perform grinding operations on the board material; Figure 3As shown, when grinding the inner circle of a pipe, the grinding driver 22 is adjusted so that the axis of the transmission rod 23 is parallel to the travel direction of the transmission unit 1. The transmission unit 1 drives the grinding unit 2 to reciprocate, and the grinding driver 22 drives the transmission rod 23 and the grinding wheel 24 to rotate, extending into the inner circle of the pipe to complete the grinding. In this application, the grinding driver 22 is detachably mounted on the grinding support frame 21, allowing the grinding device to flexibly switch the direction of the axis of the transmission rod 23. By adjusting the direction of the grinding driver 22, it can adapt to two different operating scenarios: plate grinding and inner circle grinding of pipes. There is no need to equip multiple sets of special grinding tools, which greatly improves the versatility and practicality of the device and reduces the cost of use. The reciprocating movement of the grinding unit 2 driven by the transmission unit 1, combined with the rotation of the grinding wheel 24, makes the grinding more uniform and efficient, ensuring the grinding quality and solving the problem of the single function of traditional tools.

[0027] like Figure 2 As shown, the grinding support frame 21 is provided with a height adjustment unit 3. The height adjustment unit 3 includes a height adjustment screw 31 and a height adjustment plate 32 that is threadedly engaged with it. An adjustment handle 33 is fixedly provided at the top of the height adjustment screw 31. The height adjustment plate 32 is placed in the grinding support frame 21. The grinding driver 22 is detachably installed on the height adjustment plate 32.

[0028] Specifically, a height adjustment unit 3, consisting of a height adjustment screw 31, a height adjustment plate 32, and an adjustment handle 33, is installed on the grinding support frame 21. The adjustment handle 33 has anti-slip ridges. Rotating the adjustment handle 33 allows the threaded engagement of the screw and nut to drive the height adjustment plate 32 to rise and fall within the grinding support frame 21, flexibly adjusting the height of the grinding driver 22 and the grinding wheel 24 to accommodate workpieces of different thicknesses or pipe diameters. The grinding driver 22 is detachably mounted on the height adjustment plate 32. Combined with the height adjustment function, it can change the angle between the axis of the transmission rod 23 and the travel direction of the transmission unit 1 (suitable for grinding the inner diameter of plates and pipes), and can also adapt to different size requirements through height adjustment, further improving the adaptability and flexibility of the device, reducing equipment investment and replacement operations, and improving the efficiency and convenience of grinding operations.

[0029] like Figure 4 As shown, the transmission unit 1 includes a transmission driver 11, a driving transmission wheel 12, a conveyor belt 13, a driven transmission wheel 14, and a guide rail 15. A slider 16 is provided on the guide rail 15, and the grinding unit 2 is fixedly provided on the slider 16. The conveyor belt 13 is connected to the slider 16.

[0030] Specifically, the transmission unit 1 forms a power transmission system through the transmission driver 11, the driving transmission wheel 12, the conveyor belt 13, and the driven transmission wheel 14. The transmission drivers 11 are all servo motors, working in conjunction with the guide rail 15 and the slider 16. On one hand, the conveyor belt 13, connected to the slider 16, can stably drive the grinding unit 2 to move precisely back and forth along the guide rail 15, ensuring the linearity and uniformity of movement during grinding and improving grinding quality. On the other hand, the guide rail 15 and the slider 16 provide stable support and guidance for the grinding unit 2, making its reciprocating motion smoother and less prone to deviation. Rubber buffer blocks are installed at both ends of the guide rail 15 to prevent rigid collisions between the guide rail ends and the slider 16, extending the service life of the guide rail 15, slider 16, and other related structural components.

[0031] like Figure 1 As shown, at least one grinding wheel 24 is provided on the transmission rod 23 along the axial direction.

[0032] Specifically, in this embodiment, a grinding wheel 24 is installed on the transmission rod 23. The user can flexibly adjust the number of grinding wheels 24 according to the grinding area, complexity, and process requirements of the carbon fiber reinforced composite material. A single grinding wheel 24 is suitable for fine grinding of small areas or local repairs; when multiple grinding wheels 24 are installed side by side, the grinding coverage area can be greatly increased, significantly improving the grinding efficiency of large-area plates or long-diameter pipes, and a larger area of ​​grinding work can be completed in one move. At the same time, multiple grinding wheels can also be combined with different specifications and materials to achieve continuous operation of multiple processes such as rough grinding and fine grinding for different areas and different grinding stages, reducing the number of equipment adjustments, optimizing the grinding process, and enhancing the adaptability and practicality of the grinding device to diverse working conditions.

[0033] This application discloses a grinding device for carbon fiber reinforced composite materials. When grinding a sheet material, the grinding driver 22 is mounted on the grinding support frame 21 with the axis of the transmission rod 23 perpendicular to the travel direction of the transmission unit 1. The transmission unit 1 drives the grinding unit 2 to move back and forth in a straight line. At the same time, the grinding driver 22 drives the transmission rod 23 to rotate, thereby causing the grinding wheel 24 to rotate and perform grinding operations on the sheet material. When grinding the inner circle of a pipe, the grinding driver 22 is adjusted to a state where the axis of the transmission rod 23 is parallel to the travel direction of the transmission unit 1. The transmission unit 1 drives the grinding unit 2 to move back and forth, and the grinding driver 22 drives the transmission rod 23 and the grinding wheel 24 to rotate, extending into the inner circle of the pipe to complete the grinding. In this application, the grinding driver 22 is detachably mounted on the grinding support frame 21, allowing the grinding device to flexibly switch the axis direction of the transmission rod 23. By adjusting the direction of the grinding driver 22, it can adapt to two different operating scenarios: plate grinding and pipe inner circle grinding. There is no need to equip multiple sets of special grinding tools, which greatly improves the versatility and practicality of the device and reduces the cost of use. The transmission unit 1 drives the grinding unit 2 to reciprocate and move in coordination with the rotation of the grinding wheel 24, which can make the grinding more uniform and efficient, ensure the grinding quality, and solve the problem of the single function of traditional tools.
