Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a fixture for polishing a flexible disk, including a base 1 and a mounting seat 2. A mounting seat 2 is arranged directly above the base 1. A mounting frame 3 is fixedly connected to the side of the mounting seat 2. A clamping mechanism 4 for limiting the flexible disk is jointly arranged on the mounting seat 2 and the mounting frame 3;

[0023] The clamping mechanism 4 includes a forward and reverse motor 41, a lead screw 42, a moving block 43, a slider 44, a fixed block 45, a clamping block 46, and a chute 47. A forward and reverse motor 41 is fixedly installed on the side of the mounting frame 3. A lead screw 42 is fixedly connected to the output end of the forward and reverse motor 41. A moving block 43 is threadedly connected to the outside of the lead screw 42. A slider 44 is fixedly connected to the side of the moving block 43. A fixed block 45 is fixedly connected to the upper end of the moving block 43. A clamping block 46 is fixedly connected to the fixed block 45. A chute 47 is opened in the mounting seat 2.

[0024] In this utility model, by setting the cooperation of each component in the clamping mechanism 4, starting the forward and reverse motor 41 to drive the threaded movement between the lead screw 42 and the moving block 43 can drive the moving block 43 to move and drive the clamping block 46 to clamp the flexible disk. The flexible disk is clamped in four directions, and the adjustable range of clamping the flexible disk is larger.

[0025] The slider 44 is slidably connected to the chute 47, and the moving block 43 is slidably connected to the mounting seat 2.

[0026] It is fixed on the moving block 43 through the slider 44, and the slider 44 slides in the chute 47. The moving block 43 can be guided through the slider 44.

[0027] A driving motor 5 is fixedly installed at the upper end of the base 1. A square rod 6 is fixedly connected to the output end of the driving motor 5. A square groove 7 is formed in the mounting seat 2. The square rod 6 is slidably connected in the square groove 7. An installation mechanism 8 for facilitating the rotary installation of the mounting seat 2 is jointly provided in the square rod 6 and the mounting seat 2.

[0028] By driving the square rod 6 to rotate through the driving motor 5, and the square rod 6 slides in the square groove 7 formed in the mounting seat 2, the mounting seat 2 can be driven to rotate through the rotation of the square rod 6, which is convenient for rotating the flexible disk installed in the mounting seat 2.

[0029] The installation mechanism 8 includes a card slot 81, a pin 82, an installation groove 83, a guide rod 84, and a spring 85. A card slot 81 is formed in the square rod 6. A pin 82 is slidably connected in the card slot 81. An installation groove 83 is formed at the lower end of the mounting seat 2. A guide rod 84 is fixedly connected in the installation groove 83. The pin 82 is slidably connected in the card slot 81, and the pin 82 is slidably connected to the outside of the guide rod 84. A spring 85 is sleeved on the outside of the guide rod 84.

[0030] By pulling the pin 82 to make the pin 82 slide out of the card slot 81 formed in the square rod 6, the limit on the square rod 6 can be released at this time, and moving the square rod 6 can separate the mounting seat 2 from the base 1.

[0031] One end of the spring 85 is fixedly connected to the pin 82, and the other end of the spring 85 is fixedly connected in the installation groove 83.

[0032] When the pin 82 moves, the spring 85 can be compressed, and then the pin 82 can be moved under the elastic action of the spring 85.

[0033] A ring groove 9 is formed at the upper end of the base 1. A support rod 10 is slidably connected in the ring groove 9. The support rod 10 is fixedly connected to the lower end of the mounting seat 2.

[0034] The shape of the support rod 10 is adapted to the ring groove 9. Through the support rod 10, the placement of the mounting seat 2 can be made more stable, and when the mounting seat 2 rotates, its rotation is also more stable.

[0035] During specific use, when the flexible disk is placed on the mounting seat 2, the forward and reverse motor 41 can be started. Under the drive of the forward and reverse motor 41, a threaded movement can occur between the lead screw 42 and the moving block 43. At this time, the moving block 43 drives the fixed block 45 and the clamping block 46 fixed thereon to move, so as to clamp the flexible disk through the clamping block 46. The clamping blocks 46 in four directions can make the clamping of the flexible disk more stable;

[0036] Moreover, the drive motor 5 can be started to drive the rotation of the square rod 6 fixed on the drive motor 5, thereby driving the rotation of the mounting seat 2, enabling the rotational adjustment of the flexible disk mounted on the mounting seat 2. Also, by pulling the retaining pin 82, the retaining pin 82 can be slid out of the card slot 81 formed in the square rod 6. At this time, the limit on the square rod 6 can be released, and the mounting seat 2 can be moved to complete the separation. When installing the mounting seat 2, align the square groove 7 of the mounting seat 2 with the square rod 6. Then, release the retaining pin 82. Under the elastic action of the spring 85, the retaining pin 82 can move and slide back into the card slot 81 formed in the square rod 6, thus completing the installation of the mounting seat 2.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
