[0002] In modern industrial production, the surface quality of the enclosure, as a widely used component, directly affects the appearance, performance, and service life of the product. Therefore, grinding and polishing the surface of the enclosure is of utmost importance.
[0003] Traditional methods of grinding and polishing cabinet surfaces rely heavily on manual operation, which is not only inefficient but also susceptible to variations in operator skill and work condition, making it difficult to ensure uniformity and consistency. This often results in over- or under-grinding in certain areas, leading to inconsistent product quality. Furthermore, existing cabinet grinding and polishing equipment lacks flexibility, making it difficult to comprehensively cover different areas of the cabinet surface, especially for cabinets with complex shapes and diverse sizes, where precise positioning of the grinding area is challenging. To address these issues, this application proposes a cabinet surface grinding and polishing device to improve upon these problems. Utility Model Content

[0025] Please see the appendix Figures 1 to 4 As shown, this utility model provides a grinding and polishing device for a box surface, including a frame 10. A longitudinal moving mechanism 11 is mounted at one end inside the frame 10. A transverse moving mechanism 20 is mounted at the upper end of the longitudinal moving mechanism 11. A connecting plate 30 is fixed to the lower end of the transverse moving mechanism 20. A guard plate 31 is fixed to the lower end of the connecting plate 30. A base plate 32 is fixed to the lower end of the guard plate 31. A second electric push rod 33 is fixed to one side of the upper end of the base plate 32. A fixing plate 34 is fixed to the output end of the second electric push rod 33. A sliding plate 35 is fixed to the upper end of the base plate 32 and at one end of the second electric push rod 33. A rack 36 is slidably connected to the upper end of the sliding plate 35. The fixing plate 34 and... A rack 36 is fixedly connected, and a gear 37 is provided at the upper end of the rack 36. The rack 36 and the gear 37 are meshed together. A rotating rod 38 is fixed inside the gear 37. A second support plate 39 is fixed at the upper end of the base plate 32 and on the side of the slide plate 35 away from the second electric push rod 33. One side of the rotating rod 38 passes through the second support plate 39. The rotating rod 38 and the second support plate 39 are rotatably connected. A support plate 40 is fixed on the side of the rotating rod 38 away from the gear 37. A third motor 41 is fixed at the upper end of the support plate 40. The output end of the third motor 41 extends to the lower end of the support plate 40. A polishing wheel 42 is fixed at the output end of the third motor 41 and at the lower end of the support plate 40.
[0026] In this embodiment, within the frame 10, the longitudinal moving mechanism 11 first drives the transverse moving mechanism 20 to move longitudinally. The transverse moving mechanism 20 then drives the connecting plate 30 connected to it to move laterally. A guard plate 31 is fixed to the lower end of the connecting plate 30, and a base plate 32 is fixed to the lower end of the guard plate 31, thereby enabling the transverse movement of components such as the base plate 32. When it is necessary to adjust the tilt angle of the polishing wheel 42, the second electric push rod 33 is activated. The second electric push rod 33 can precisely control the extension and retraction length according to actual needs. Its output end drives the fixed plate 34, which is fixedly connected, to move linearly. Since the fixed plate 34 is fixedly connected to one end of the rack 36, the rack... The rack 36 is slidably connected to the upper end of the slide plate 35, allowing it to slide on the slide plate 35. Because the rack 36 is tightly meshed with the gear 37, the linear motion of the second electric push rod 33 is converted into the rotational motion of the gear 37. The rotation of the gear 37 drives the rotating rod 38, which is fixed inside it, to rotate. The end of the rotating rod 38 furthest from the gear 37 is fixed to the support plate 40, the third motor 41, and the polishing wheel 42. Therefore, changes in the angle of the rotating rod 38 synchronously adjust the angle of the polishing wheel 42, ensuring that the polishing wheel 42 can adhere to the surface of the housing at a suitable tilt angle, effectively avoiding uneven polishing or over-polishing caused by angle deviation. It should be noted that the rotating rod 38 is rotatably connected inside the second support plate 39, and there is no longitudinal movement between the rotating rod 38 and the second support plate 39.
[0027] In a preferred embodiment, please refer to Figure 1 and Figure 4 The lateral moving mechanism 20 includes a second motor 21, a third threaded rod 22, a moving block 23, a support block 24, and a first electric push rod 25. The guard plate 31 is fixed to one side of the upper end of the longitudinal moving mechanism 11. The output end of the second motor 21 is fixed to the third threaded rod 22. The moving block 23 is threaded to the outside of the third threaded rod 22. The support block 24 is fixed to one end of the moving block 23. The first electric push rod 25 is fixed to the upper end of the support block 24, and the output end of the first electric push rod 25 extends to the lower end of the support block 24. The output end of the first electric push rod 25 is fixedly connected to the connecting plate 30.
[0028] In this embodiment, when the surface of the box needs to be horizontally polished, the second motor 21 is started. The second motor 21 is fixed to the upper end of the moving plate 14. The rotation of the second motor 21 drives the third threaded rod 22 fixed to its output end to rotate. Since the moving block 23 is threaded to the outside of the third threaded rod 22 and the cross-sectional shape of the moving block 23 is cross-shaped, under the action of the threaded transmission, the moving block 23 will move horizontally in a straight line along the third threaded rod 22, thereby driving the support block 24 fixed to one end of the moving block 23 to move horizontally in sync. The first electric push rod 25 fixed to the upper end of the support block 24 has its output end connected to the connecting plate 30. When the first electric push rod 25 extends or retracts, the height position of the connecting plate 30 and the guard plate 31, bottom plate 32 and other components connected below it can be adjusted, so that the polishing wheel 42 installed on the bottom plate 32 can accurately correspond to the area of different heights and positions on the surface of the box for polishing operations.
[0029] Secondly, please refer to it again. Figure 1 and Figure 5 The longitudinal moving mechanism 11 includes a first motor 12, a first threaded rod 13, a moving plate 14, and a first limiting rod 15. The first motor 12 is fixed to one end of the frame 10. The first threaded rod 13 is fixed to the output end of the first motor 12 and is rotatably connected to the inside of the frame 10. The moving plate 14 is threaded to the outside of the first threaded rod 13. The upper end of the moving plate 14 extends to the upper end of the frame 10. The first limiting rod 15 is fixed to the inside of the frame 10 and is located at the lower end of the first threaded rod 13. The moving plate 14 and the first limiting rod 15 are slidably connected.
[0030] In this embodiment, when longitudinal grinding and polishing of the housing surface is required, the first motor 12 is started, driving the first threaded rod 13 fixed at its output end to rotate. Since the moving plate 14 is threaded to the outside of the first threaded rod 13, under the action of the threaded transmission principle, the moving plate 14 will move longitudinally in a straight line along the first threaded rod 13. At the same time, the moving plate 14 slides along the first limiting rod 15 fixed inside the frame 10 during the movement. The first limiting rod 15 plays a guiding and limiting role, ensuring that the moving plate 14 remains stable during the longitudinal movement and will not deviate or shake. The upper end of the moving plate 14 extends to the upper end of the frame 10, and the upper end of the moving plate 14 is equipped with a transverse moving mechanism 20, thereby driving the transverse moving mechanism 20 and the connecting plate 30, guard plate 31, bottom plate 32 and other components below it to perform longitudinal displacement, realizing grinding and polishing of different longitudinal positions on the housing surface.
[0031] It should be noted that the first motor 12, the second motor 21, the third motor 41, the first electric push rod 25, and the second electric push rod 33 are all connected by wires and external power supply through wires, and are controlled by a controller (not shown in the figure, existing technology, and will not be described in detail).
[0032] Secondly, please refer to the following as well. Figure 2 and Figure 5 The upper end of the frame 10 is provided with a through hole 16. Inside the frame 10 and below the through hole 16, a first support plate 17 is fixed. A second threaded rod 18 is rotatably connected between the first support plate 17 and the frame 10. A first clamping plate 19 is threadedly connected to the outer side of the second threaded rod 18. The first clamping plate 19 passes through the through hole 16 and extends to the upper end of the frame 10. A second limiting rod 45 is fixed between the first support plate 17 and the frame 10 and below the second threaded rod 18. The first clamping plate 19 and the second limiting rod 45 are slidably connected.
[0033] In this embodiment, when it is necessary to fix the box, the box to be polished is placed between the first clamping plate 19 and the second clamping plate 46. The second threaded rod 18 is rotated. Since the first clamping plate 19 is threadedly connected to the second threaded rod 18, and the first clamping plate 19 passes through the through hole 16 at the upper end of the frame 10 and is slidably connected with the second limiting rod 45, the first clamping plate 19 will move laterally along the second limiting rod 45 under the action of threaded transmission. As the second threaded rod 18 continues to rotate, the first clamping plate 19 gradually approaches the position on the upper surface of the frame 10 where the box is placed, until it cooperates with the upper surface of the frame 10 to clamp and fix the box, so as to avoid displacement of the box during the polishing process, which would affect the processing accuracy and safety.
[0034] In a preferred embodiment, please refer to Figure 1 The end of the second threaded rod 18 away from the first support plate 17 extends to the outside of the frame 10, and a handwheel 47 is fixed to one end of the second threaded rod 18.
[0035] In this embodiment, the second threaded rod 18 is rotated by the handwheel 47, which makes it easy for the operator to apply force directly and conveniently, thus improving the efficiency of box clamping.
[0036] To further understand and explain, Figure 1 For example, a second clamping plate 46 is fixed at the upper end of the frame 10. The second clamping plate 46 and the first clamping plate 19 are provided with anti-slip surfaces on their respective sides. The anti-slip surfaces are made of rubber.
[0037] In this embodiment, the rubber anti-slip surface will not damage the surface of the box, thus maintaining the integrity of the surface.
[0038] The working principle of this utility model is as follows:
[0039] During operation, rotating the handwheel 47 on the outside of the frame 10 drives the second threaded rod 18 to rotate, causing the first clamping plate 19, which is threadedly connected to the second threaded rod 18 and guided by the second limiting rod 45, to move. The second clamping plate 46, in conjunction with the rubber anti-slip surface, clamps and fixes the housing. During longitudinal grinding, the first motor 12 is started, driving the first threaded rod 13 to rotate, causing the moving plate 14, which is threadedly connected to the first threaded rod 13 and guided by the first limiting rod 15, to move longitudinally. This, in turn, drives the transverse moving mechanism 20 and the connecting plate 30, guard plate 31, base plate 32, and other components below to move longitudinally. During transverse grinding, the second motor 21 is started, driving the third threaded rod 19 to rotate. The rotation of the threaded rod 22 causes the moving block 23, which is threadedly connected to the third threaded rod 22, to move laterally, thereby causing the support block 24, the first electric push rod 25, and the connecting plate 30 to move laterally. At the same time, the first electric push rod 25 extends and retracts to adjust the height of the polishing wheel 42. When adjusting the angle of the polishing wheel 42, the second electric push rod 33 is activated, which drives the fixed plate 34 to move linearly. This causes the rack 36 connected to the fixed plate 34 to slide on the slide plate 35. Through the meshing of the rack 36 and the gear 37, the rotating rod 38 is driven to rotate, thereby adjusting the angle of the polishing wheel 42. Finally, the third motor 41 drives the polishing wheel 42 to grind and polish the surface of the box.
[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
