It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] As described in the background art, the aforementioned fixing device requires manual reassembly of the metal sheet when adjusting the polished surface to the unpolished surface, which is quite troublesome.

[0027] To solve this technical problem, the present invention provides a fixing device.

[0029] The present invention provides a fixing device that is adjustable through the design of the clamping mechanism to accommodate metal sheets of different sizes, while ensuring the stability of the metal sheet during grinding, thereby improving the precision and efficiency of grinding. By flipping the rotating plate 5, the metal sheet can be quickly flipped from the ground surface to the unground surface. The locking mechanism provides a more stable connection and prevents the rotating plate 5 from moving or flipping due to vibration or external force during grinding, thus ensuring the safety of the metal sheet during grinding.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1

[0033] Reference Figures 1-4 A fixing device includes a placement platform 1. Sliding grooves 2 are provided on the inner sides of both sides of the placement platform 1. A first sliding plate 3 is slidably connected to the inner side of each of the two sliding grooves 2. A connecting plate 4 is rotatably connected to the inner side of the top of each of the first sliding plates 3. A rotating plate 5 is fixed to one end of each of the two connecting plates 4. A clamping mechanism is provided at each of the four corners of the inner side of the rotating plate 5. The clamping mechanism is used to clamp and fix the metal sheet. A snap-fit ​​mechanism is provided on the inner side of both ends of the placement platform 1. The snap-fit ​​mechanism is used to connect the rotating plate 5 and the placement platform 1.

[0034] The clamping mechanism includes a knob 7, a threaded rod 8, a second sliding plate 9, and a clamping plate 10. The four corners of the inner side of the rotating plate 5 are rotatably connected to the knob 7. One end of the knob 7 is fixed with the threaded rod 8. The threaded rod 8 is rotatably connected to the rotating plate 5. The outer side of the threaded rod 8 is threadedly connected to the second sliding plate 9. The second sliding plate 9 is slidably connected to the rotating plate 5. One end of the second sliding plate 9 is fixed with the clamping plate 10.

[0035] The clamping mechanism is designed to be adjustable to accommodate metal sheets of different sizes, while ensuring the metal sheets remain stable during grinding, thus improving grinding accuracy and efficiency.

[0036] Example 2

[0037] Reference Figures 5-7 A fixing device, the snap-fit ​​mechanism includes a first snap-fit ​​plate 12, a third sliding plate 13, a second snap-fit ​​plate 14, a pull plate 15, a fixing plate 16 and a spring 17. The top and bottom of one end of the rotating plate 5 are both fixed with the first snap-fit ​​plate 12. The inner sides of both ends of the placement platform 1 are slidably connected with the third sliding plate 13. The ends of the two third sliding plates 13 that are close to each other are both fixed with the second snap-fit ​​plate 14. The ends of the two third sliding plates 13 that are far apart from each other are both fixed with the pull plate 15. The top and bottom of the third sliding plate 13 are both fixed with the fixing plate 16. The two fixing plates 16 are both located inside the placement platform 1. The two fixing plates 16 are both slidably connected to the placement platform 1. The spring 17 is fixed to one end of the two fixing plates 16.

[0038] By flipping the rotating plate 5, the metal sheet can be quickly flipped from the polished surface to the unpolished surface. The locking mechanism can provide a more stable connection and prevent the rotating plate 5 from moving or flipping due to vibration or external force during the polishing process, thereby ensuring the safety of the metal sheet during polishing.

[0039] The inner side of the first snap-fit ​​plate 12 is provided with a snap-fit ​​groove 18. The second snap-fit ​​plate 14 is snapped into the first snap-fit ​​plate 12 through the snap-fit ​​groove 18. The snap-fit ​​between the second snap-fit ​​plate 14 and the first snap-fit ​​plate 12 fixes the position of the rotating plate 5. A pad 6 is fixed on the top of the placement platform 1. The bottom of the rotating plate 5 is in contact with the top of the pad 6. The pad 6 is provided to prevent the metal sheet from being detached from the clamping plate 10 due to the force on the top. Guide rods 11 are fixed on both sides of the clamping plate 10. Both guide rods 11 are slidably connected to the rotating plate 5. The guide rods 11 guide the movement of the clamping plate 10.

[0040] The process of using the fixing device provided by this utility model is as follows: Place the metal sheet on the pad 6. At this time, the metal sheet is located between multiple clamping plates 10. Then rotate the knob 7. Since the knob 7 is fixedly connected to the threaded rod 8, the rotation of the knob 7 drives the threaded rod 8 to rotate. Since the threaded rod 8 is threadedly connected to the second sliding plate 9 and the second sliding plate 9 is slidably connected to the rotating plate 5, the rotation of the threaded rod 8 drives the second sliding plate 9 to slide. Thus, the clamping plate 10 fixedly connected to the second sliding plate 9 moves along with it. At this time, the clamping plate 10 contacts the metal sheet. Repeat the above operation and rotate the knob 7 so that the multiple clamping plates 10 clamp the metal sheet on the inner side of the rotating plate 5.

[0041] The clamping mechanism is designed to make the fixing device adjustable to accommodate metal sheets of different sizes, while ensuring that the metal sheets remain stable during the grinding process, thereby improving the precision and efficiency of grinding.

[0042] After one side of the metal sheet is polished, pull one end of the pull plate 15. Since the pull plate 15 is fixedly connected to the third sliding plate 13, the movement of the pull plate 15 causes the third sliding plate 13 to move. Since the third sliding plate 13 is fixedly connected to the second snap-fit ​​plate 14, the movement of the third sliding plate 13 causes the second snap-fit ​​plate 14 to move, so that the second snap-fit ​​plate 14 is no longer snapped to the first snap-fit ​​plate 12 through the snap-fit ​​groove 18. At this time, rotate the rotating plate 5, so that the metal sheet clamped by the clamping plate 10 inside the rotating plate 5 also rotates. Then push the rotating plate 5 to one side. Since the rotating plate 5 is fixedly connected to the connecting plate 4 and the connecting plate 4 is rotatably connected to the first sliding plate 3, and the first sliding plate 3 is slidably connected to the placement platform 1 through the sliding groove 2, the movement of the rotating plate 5 after rotation causes the first sliding plate 3 to move to one side. As the rotating plate 5 rotates, the first snap-fit ​​plate 12, which is located at the top before rotation, is inserted into the groove at one end of the placement platform 1. At this time, the inclined surface at the bottom of the first snap-fit ​​plate 12 contacts the inclined surface at one end of the second snap-fit ​​plate 14, pressing the second snap-fit ​​plate 14 towards the inside of the placement platform 1. Since the second snap-fit ​​plate 14 is fixedly connected to the third sliding plate 13 and the third sliding plate 13 is fixedly connected to the fixed plate 16, the movement of the second snap-fit ​​plate 14 causes the fixed plate 16 to move, thereby compressing the spring 17 fixedly connected to the fixed plate 16. When the first snap-fit ​​plate 12 is inserted into the groove and the snap-fit ​​groove 18 is opposite to the second snap-fit ​​plate 14, the second snap-fit ​​plate 14 is snapped into the first snap-fit ​​plate 12 through the snap-fit ​​groove 18 under the push of the spring 17. At this time, the rotating plate 5 is fixed. At this time, the metal sheet fixed to the inside of the rotating plate 5 by the clamping plate 10 is flipped over, which makes it convenient to polish the unpolished surface.

[0043] By flipping the rotating plate 5, the metal sheet can be quickly flipped from the polished surface to the unpolished surface. The locking mechanism can provide a more stable connection and prevent the rotating plate 5 from moving or flipping due to vibration or external force during the polishing process, thereby ensuring the safety of the metal sheet during polishing.
