DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a plate processing fixture, comprising a fixture table 1, an inner cavity 2 is provided inside the fixture table 1, a through slot 3 is provided on the top of the inner cavity 2, a fixing plate 4 is fixed inside the inner cavity 2, and a clamping mechanism 5 is provided on the fixture table 1;

[0021] The clamping mechanism 5 includes a first rotating shaft 51, and the inner wall of the inner cavity 2 is rotatably mounted with the first rotating shaft 51 through a bearing. The end of the first rotating shaft 51 passes through the interior of the fixed plate 4 and is fixed with a first bevel gear 52. The bottom of one side of the first bevel gear 52 is meshed with a second bevel gear 53. The center of the bottom of the second bevel gear 53 is fixed with a second rotating shaft 54. The lower end of the second rotating shaft 54 ​​is rotatably connected to the center of the bottom of the inner cavity 2 through a bearing. A clamping plate 55 is nested on the outer side of the first rotating shaft 51. A guide rod 56 passes through the bottom of the clamping plate 55. The two ends of the guide rod 56 are respectively fixedly connected to one side of the fixed plate 4 and the inner wall of the inner cavity 2. The top of the clamping plate 55 passes through the interior of the through groove 3. A first handle 57 is fixed to the end of the first rotating shaft 51. The first handle 57 is located outside the clamping table 1.

[0022] A fixing mechanism 6 is provided at the top of one side of the clamping plate 55, and the fixing mechanism 6 includes a fixing block 61. The fixing block 61 is fixed at the top of one side of the clamping plate 55, and a screw rod 62 passes through the middle of the fixing block 61. A clamping block 63 is rotatably installed at the lower end of the screw rod 62 through a bearing. A slider 64 is fixed to one side of the clamping block 63, and one end of the slider 64 is located inside a slide groove 65. The slide groove 65 is opened on one side of the clamping plate 55, and a second handle 66 is fixed to the top of the screw rod 62.

[0023] There are four first bevel gears 52, first rotating shafts 51, clamping plates 55 and guide rods 56 distributed at equal angles about the central axis of the second bevel gear 53. The first rotating shaft 51 and the clamping plates 55 are threadedly connected, and the clamping plates 55 and the guide rods 56 are slidingly connected. The threads on the two first rotating shafts 51 located on the same straight line are in the same direction, which ensures that when the first rotating shaft 51 rotates, the first rotating shaft 51 can drive the first bevel gear 52 and the second bevel gear 53 to rotate simultaneously, and then the second bevel gear 53 can drive the other three first bevel gears 52 to rotate simultaneously, thereby making the four first rotating shafts 51 rotate simultaneously, so that the four clamping plates 55 move towards each other or move away from each other, so that the four clamping plates 55 can clamp and fix circular plates of different diameters.

[0024] The inner wall of the through slot 3 and the outer wall of the clamping plate 55 are in contact with each other, and the clamping plate 55 and the through slot 3 form a sliding structure, which ensures that the clamping plate 55 can slide inside the through slot 3.

[0025] A rotating structure is formed between the outer wall of the first rotating shaft 51 and the inner wall of the fixing plate 4 via a bearing, thereby ensuring that the first rotating shaft 51 can rotate on the fixing plate 4 and will not separate from the fixing plate 4 .

[0026] The fixing block 61 and the screw rod 62 are threadedly connected, ensuring that the screw rod 62 can move up and down on the fixing block 61 when the screw rod 62 rotates.

[0027] The outer wall of the slider 64 and the inner wall of the slide groove 65 fit each other, and the slider 64 and the slide groove 65 form a snap-fit ​​sliding structure, which ensures that the clamping block 63 can move up and down stably without rotating under the limitation of the slider 64 and the slide groove 65.

[0028] Working principle: When using the plate processing fixture, first place the circular plate to be fixed between the four clamping plates 55, then rotate the first handle 57, and then the first handle 57 drives the first rotating shaft 51 and the first bevel gear 52 to rotate, and then the first bevel gear 52 drives the second bevel gear 53 and the second rotating shaft 54 ​​to rotate simultaneously, and at the same time, the second bevel gear 53 drives the other three first bevel gears 52 to rotate simultaneously, so the four first bevel gears 52 rotate simultaneously, and at the same time, the four first bevel gears 52 drive the four first rotating shafts 51 to rotate simultaneously, because the first rotating shaft 51 and the clamping plate 55 are threadedly connected, and the clamping plate 55 and the guide rod 56 are slidably connected, and the threads on the two first rotating shafts 51 located on the same straight line are in the same direction, so that the four clamping plates 55 move closer to each other to clamp and fix the circular plate;

[0029] Then rotate the second handle 66, and the second handle 66 drives the screw rod 62 to rotate. Since the fixing block 61 and the screw rod 62 are threadedly connected, the screw rod 62 pushes the clamping block 63 and the slider 64 to move downward, so that the clamping block 63 fixes the top side of the circular plate to avoid the side warping when the circular plate is processed.

[0030] Although the utility model has been described in detail according to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
