[0002] To ensure excellent electromagnetic shielding performance, reliable welding and grounding performance, and long-term corrosion resistance, the shielding cover usually needs to be ground and polished to remove burrs and oxide layers and obtain a uniform and smooth surface roughness.

[0003] Currently, many production scenarios still rely on operators holding hand shields to grind on grinding wheels and belt sanders. The grinding effect is highly dependent on the operator's skill level and working condition, making it difficult to guarantee the uniformity of surface roughness and material removal between different workpieces, and even between different areas of the same workpiece. Uneven pressure can easily cause surface scratches or localized over-grinding, creating new quality defects. Utility Model Content

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0016] Please see Figures 1 to 6 The shielding cover surface polishing device according to one embodiment of the present invention includes a machine base 10, a transfer component 20 installed on the top surface of the machine base 10, and a polishing component 30 installed on the top surface of the machine base 10.

[0017] The transfer assembly 20 includes two X-axis linear modules 21 mounted side by side on the top surface of the machine tool 10, and a fixture 22 connecting the slides of each X-axis linear module 21; the fixture 22 is used to fit and load multiple shields 23 to be polished.

[0018] The polishing assembly 30 includes an extension frame 31 located at one end of the X-axis linear module 21, a Y-axis linear module 32 mounted on the extension frame 31, a Z-axis linear module 33 connected to the slide of the Y-axis linear module 32, a support plate 34 connected to the slide of the Z-axis linear module 33, a bracket 35 fixedly connected to the support plate 34, a rotating shaft 36 rotatably connected to the bottom end of the bracket 35, an electric grinder 37 fixedly connected to the end of the rotating shaft 36, and a motor 38 mounted on the top end of the bracket 35. The motor 38 is used to drive the rotating shaft 36 to rotate around its own axis, thereby driving the electric grinder 37 to swing at a preset angle. The electric grinder 37 is located above the fixture 22 to facilitate polishing the surface of the shield 23. Compared with traditional grinding methods, this utility model uses a motor 38 to drive an electric grinder 37 to achieve automated angle swing, replacing manual hand operation. This allows for flexible adjustment of the grinding angle, facilitating comprehensive and uniform automatic grinding of different areas of the shielding cover 23, and effectively ensuring the processing consistency and quality of each workpiece and different areas of the same workpiece.

[0019] In this embodiment, the axis of the rotating shaft 36 is set along the X-axis direction, and the axis of the rotating shaft 36 is perpendicular to the axis of the electric grinder 37, ensuring that the swing trajectory of the electric grinder 37 meets the grinding process requirements of the shield 23.

[0020] Specifically, the bracket 35 has a through hole 350 along the X-axis, and the rotating shaft 36 is fitted and installed inside the through hole 350 via a bearing 360, so as to realize the rotatable connection between the rotating shaft 36 and the bracket 35. Figure 4 and Figure 5 As shown, two limiting posts 351 are circumferentially spaced on the bracket 35 corresponding to the rotating shaft 36. A slotted photoelectric switch 352 is installed on one side of the bracket 35 corresponding to each limiting post 351. A protrusion 361 is connected to one end of the rotating shaft 36 that connects to the electric grinder 37, and a sensing plate 362 is connected to the end of the protrusion 361 away from the rotating shaft 36. The protrusion 361 is located between the two limiting posts 351, and the limiting posts 351 abut against the protrusion 361 to form a mechanical limit when the rotating shaft 36 rotates. The sensing plate 362 matches the slot of the corresponding slotted photoelectric switch 352 to form a photoelectric limit when the rotating shaft 36 rotates. Through the synergistic effect of the limiting posts 351 and the slotted photoelectric switch 352, the rotation angle travel of the rotating shaft 36 can be precisely limited, thereby accurately controlling the angular swing range of the electric grinder 37 and avoiding excessive swing that could lead to grinding deviations.

[0021] In this embodiment, two slotted photoelectric switches 352 are arranged at a 90° angle along the circumference of the rotating shaft 36, meaning that the two slotted photoelectric switches 352 are respectively located at the two extreme positions of the electric mill 37's swing. When the sensing plate 362 rotates with the rotating shaft 35 to the slotted photoelectric switch 352 on the triggering side, the electric mill 37 reaches the 0° swing limit, at which point the axis of the electric mill 37 is perpendicular to the top surface of the shield 23; when the sensing plate 362 rotates with the rotating shaft 35 to the slotted photoelectric switch 352 on the triggering side, the electric mill 37 reaches the 90° swing limit, at which point the axis of the electric mill 37 is perpendicular to the side surface of the shield 23. During the processing, the 90° angle between the two slotted photoelectric switches 352 precisely matches the maximum swing requirement of the electric mill 37, and together with the limiting post 351, avoids overtravel collisions.

[0022] like Figure 6 As shown, a driven wheel 391 is coaxially mounted on the end of the rotating shaft 36 away from the electric mill 37, and a driving wheel 392 is coaxially mounted on the rotor of the motor 38. A synchronous belt 393 is sleeved between the driving wheel 392 and the driven wheel 391 to realize the transmission connection between the rotating shaft 36 and the motor 38.

[0023] The aforementioned shielding cover surface grinding device has a simple structure and is easy to use. The electric grinder 37 is driven by the motor 38 to achieve angle swing. With the cooperation of the limit post 351 and the slotted photoelectric switch 352, the angle swing range of the electric grinder 37 is precisely controlled, replacing manual hand operation. It can realize flexible adjustment of the grinding angle, which facilitates comprehensive and uniform automatic grinding of different areas of the shielding cover 23, effectively ensuring the processing consistency and processing quality of each workpiece and different areas of the same workpiece.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
