[0002] Medical plasma centrifuge is a device specially used to separate blood components in medical and biological laboratories.

[0003] At present, the turntable used to hold blood in medical plasma centrifuges usually needs to be tested for roundness by a roundness calibration device after processing for stability and centrifugal effect during use.

[0004] However, the positioning fixture of the roundness calibration equipment in the prior art usually operates independently, which is very time-consuming when calibrating the roundness of turntables in large quantities. Therefore, the utility model proposes a medical plasma centrifuge turntable processing and roundness calibration equipment to solve the above problem. Utility Model Content

[0025] See also Figures 1 to 5 , the utility model provides a technical solution:

[0026] Embodiment 1, a medical plasma centrifuge turntable processing and rounding equipment, the medical plasma centrifuge turntable processing and rounding equipment comprises: a mounting platform 1.

[0027] Specifically, one side of the installation platform 1 is rotatably connected to a first gear 2 driven by a motor 3 to rotate. One side of the first gear 2 is engaged with a toothed ring 4. The toothed ring 4 is rotatably connected to the installation platform 1, and tooth grooves are formed on both sides of the toothed ring 4. A plurality of second gears 5 distributed in a circumferential array are engaged with the inner ring of the toothed ring 4. The second gears 5 are rotatably connected to the installation platform 1, and a rack 6 is engaged with the side surface of the second gears 5. The rack 6 is slidably connected to the installation platform 1, and one end of the rack 6 is fixedly connected to a clamp block 7 arranged in a "V" shape. During actual implementation, first, the workpiece to be detected is placed at the center of the toothed ring 4. Then, the motor 3 drives the first gear 2 to rotate. The rotation of the first gear 2 will drive the toothed ring 4 to rotate. The rotation of the toothed ring 4 will drive a plurality of second gears 5 to rotate synchronously. The rotation of the second gears 5 will drive the rack 6 to slide, thereby controlling a plurality of "V"-shaped clamp blocks 7 to slide synchronously towards the workpiece direction, and finally clamping and fixing the workpiece, which is very convenient.

[0028] To facilitate the connection between the motor 3 and the first gear 2, the motor 3 of the present application is fixedly connected to the installation platform 1. A through hole 13 for the rotation and insertion of the rotating shaft of the motor 3 is formed through one side of the installation platform 1. The through hole 13 can facilitate the rotation and insertion of the rotating shaft of the motor 3 and position the motor 3, thereby ensuring the stability of the position of the first gear 2.

[0029] To facilitate the installation of the toothed ring 4, an installation groove 11 is formed on one side of the installation platform 1 of the present application. One end of the toothed ring 4 is fixedly connected to a connection block 41. The connection block 41 is rotatably connected to the installation groove 11. Through the rotational connection between the connection block 41 and the installation groove 11, while not affecting the rotation of the toothed ring 4, the toothed ring 4 can be prevented from moving.

[0030] To ensure the stable installation of the second gears 5, a placement groove 12 is formed on one side of the installation platform 1 of the present application. One end of the second gear 5 is fixedly connected to a positioning block 51. The positioning block 51 is rotatably connected to the placement groove 12. The rotational connection between the positioning block 51 and the placement groove 12 can ensure that the second gears 5 rotate without displacement.

[0031] To facilitate the sliding installation of the rack 6, a plurality of "C"-shaped installation blocks 8 are fixedly connected to the side surface of the installation platform 1 of the present application. The rack 6 is slidably connected to the installation blocks 8. The "C"-shaped installation blocks 8 can provide an installation space for the rack 6 while not affecting the rotation of the toothed ring 4, ensuring a better combination between the rack 6 and the second gears 5.

[0032] To facilitate the sliding connection between the rack 6 and the installation blocks 8, a "T"-shaped slider 61 is fixedly connected to one side of the rack 6 of the present application. A sliding groove 81 for the sliding insertion of the slider 61 is formed at one end of the installation block 8. Through the sliding insertion of the "T"-shaped slider 61 and the sliding groove 81, while ensuring the sliding of the rack 6, the rack 6 can be prevented from disengaging from the installation blocks 8.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
