[0002] Fixing devices refer to those devices and appliances that are fixedly installed. They are not mainly used for carrying people or goods, but are vehicles or devices specifically designed to perform specific tasks or operations. These devices are fixedly installed by means such as welding, riveting, or bolt connection to ensure their stability and safety.

[0003] The existing fixing device convenient for polishing quartz wafers fixes the quartz wafers and then grinds and polishes the quartz wafers. However, since the existing fixing device for polishing quartz wafers can only fix a single quartz wafer and cannot simultaneously polish multiple quartz wafers, the efficiency of grinding and polishing quartz wafers is low. Therefore, a fixing device convenient for polishing quartz wafers is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing device convenient for polishing quartz wafers to solve the problems raised in the above background art.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A fixing device for facilitating the polishing of quartz wafers, comprising a base and a polishing disc. A fixing device is provided on the top of the polishing disc. The fixing device includes a first limiting ring and two clamping fixing plates. Two L-shaped fixing plates are fixedly connected to one side of the first limiting ring, and the two L-shaped fixing plates are fixedly connected to the base. A guiding ring is fixedly connected to one side of the first limiting ring. A threaded rod is threadedly connected inside the first limiting ring and the guiding ring. An anti-slip handle is fixedly connected to one side of the threaded rod. The other side of the threaded rod is rotatably connected to a bearing, and the other clamping fixing plate is fixedly connected to the bearing. Rubber pads are fixedly connected to one side of the two clamping fixing plates. A plurality of fixing components are arranged on the surface of the first limiting ring. The fixing component includes a rectangular groove. A cylinder is fixedly connected to the inner wall of the rectangular groove. A connecting rotating ring is rotatably connected to the surface of the cylinder. A second limiting ring is fixedly connected to one side of the connecting rotating ring. A piston rod is arranged inside the second limiting ring. A clamping plate is fixedly connected to one end of the piston rod. A spring is sleeved on the surface of the piston rod. One end of the spring is fixedly connected to one side of the clamping plate. The piston rod is slidably connected to a cylinder barrel. The other end of the spring is fixedly connected to one side of the cylinder barrel. A connecting plate is fixedly connected to the bottom of the cylinder barrel, and the connecting plate is fixedly connected to the second limiting ring. A piston is slidably connected inside the cylinder barrel, and the piston is fixedly connected to the piston rod. An air pipe is fixedly connected inside the cylinder barrel. An air valve is fixedly connected to one side of the air pipe, and the air valve is arranged inside the base. A pushing air plate is slidably connected inside the air valve. An electric telescopic rod is fixedly connected to the bottom of the pushing air plate, and the electric telescopic rod is arranged inside the base. A first magnet is fixedly connected to the surface of the second limiting ring, and a second magnet is fixedly connected to the surface of the first limiting ring. The first magnet and the second magnet attract each other. A stabilizing block is fixedly connected to one side of the second limiting ring. A slot is opened inside the stabilizing block.

[0006] By setting the above structure, place the quartz wafer with a larger diameter inside the clamping fixing plate. Turn the threaded rod. When the threaded rod is turned to a position where it can clamp and fix the quartz wafer with a larger diameter, the clamping and fixing of the quartz wafer with a larger diameter can be achieved. When it is necessary to clamp and fix some quartz wafers with a smaller diameter, the movement of the piston rod will drive the clamping plate fixedly connected thereto to move, and at the same time the spring will also be compressed. At this time, the quartz wafer with a smaller diameter can be placed inside the clamping plate.

When the threaded rod is turned, when the threaded rod is turned to be able to clamp and fix the quartz wafer with a larger diameter, the clamping and fixing of the quartz wafer with a larger diameter can be achieved. When it is necessary to clamp and fix some quartz wafers with a smaller diameter, the movement of the piston rod will drive the fixedly connected clamping plate to move, and at the same time the spring will also be compressed. At this time, the quartz wafer with a smaller diameter can be placed inside the clamping plate. After the quartz wafer is placed in the clamping plate, the piston will drive the piston rod to move, and the movement of the piston rod will drive the clamping plate to move, and the clamping plate will also be reset under the action of the spring, so as to achieve the clamping and fixing of the quartz wafer with a smaller diameter, enabling the existing fixing device convenient for polishing quartz wafers to clamp and fix quartz wafers with different diameters, and at the same time being able to clamp and fix multiple quartz wafers, improving the efficiency of grinding and polishing quartz wafers.

[0027] A sponge pad 2 is provided on the top of the base 1.

[0030] Another clamping fixing plate 407 is fixedly connected to the bearing 406.

[0031] A rectangular groove 501 is formed on the surface of the first limiting ring 401. By setting the first magnet 515 and the second magnet 516, when it is not necessary to grind multiple quartz wafers, the fixing assembly 5 can be rotated to the top of the fixing device 4 for storage.

[0032] Working principle and usage process of the utility model: Place a quartz wafer with a larger diameter in the clamping fixing plate 407. By turning the threaded rod 404, the rotation of the threaded rod 404 will drive the clamping fixing plate 407 to move, and the rubber pad 408 fixedly connected to the clamping fixing plate 407 will fit with the quartz wafer with a larger diameter. When the threaded rod 404 is turned to clamp and fix the quartz wafer with a larger diameter, the clamping and fixing of the quartz wafer with a larger diameter can be achieved. When it is necessary to clamp and fix some quartz wafers with a smaller diameter, the telescopic movement of the electric telescopic rod 514 pushes the air pushing plate 513. The air pushing plate 513 will move inside the air valve 512, and then the gas inside the air valve 512 will enter the inside of the cylinder 508 through the air pipe 511. Then the piston 510 inside the cylinder 508 will move. The movement of the piston 510 will drive the piston rod 505 fixedly connected to it to move. The movement of the piston rod 505 causes the clamping plate 506 fixedly connected to it to also move, and at the same time the spring 507 will be compressed. At this time, a quartz wafer with a smaller diameter can be placed inside the clamping plate 506. After the quartz wafer is placed in the clamping plate 506, the telescopic movement of the electric telescopic rod 514 pulls the air pushing plate 513, so that the gas inside the cylinder 508 can enter the air valve 512 through the air pipe 511. At the same time, the piston 510 will drive the piston rod 505 to move. The movement of the piston rod 505 will drive the clamping plate 506 to move, and the clamping plate 506 will also reset under the action of the spring 507, thus realizing the clamping and fixing of the quartz wafer with a smaller diameter. Then move the dovetail slider 520 to drive the annular plate 522 fixedly connected to it to move. The insertion plate 523 fixedly connected to the annular plate 522 will be inserted into the slot 518 opened inside the stabilizing block 517. Then insert the fixing nail 525 into the positioning plate 524 and the L-shaped fixing plate 402, so that the dovetail slider 520 no longer moves. At this time, the connection between the insertion plate 523 and the slot 518 can fix the fixing assembly 5.
