Abstract
Description
Technical Field
[0001] This utility model relates to the field of pin-hanging fixture technology, specifically a pin-hanging fixture structure for a centrifuge horizontal rotor. Background Technology
[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a liquid-solid mixture or a liquid-liquid mixture. The main components of a centrifuge are its rotating structure, including a horizontal rotor, a turntable, and a pin. The pin often needs to be processed during manufacturing. Before processing, the pin is usually fixed by a three-jaw chuck. Since the three-jaw chuck has an inner hole, and the pin is inserted into the inner hole and then fixed by the three jaws, the processing of the pin generates a lot of debris. This debris will splash into the inner hole, which not only affects subsequent processing but also makes cleaning difficult for the workers. Utility Model Content
[0003] The purpose of this utility model is to provide a horizontal rotor pin mounting fixture structure for centrifuges to solve the problems existing in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a horizontal rotor pin mounting fixture structure for a centrifuge, including a base, and further comprising:
[0005] A fixed plate is fixedly connected to the top of the base. A fixed disk is rotatably connected to one side of the fixed plate, and a rotating shaft is fixed to the left side of the fixed disk. A three-jaw chuck is fixedly connected to the other side of the fixed disk by bolts. A first disk and a second disk are respectively arranged inside the three-jaw chuck. The first disk is fixedly connected to the inner wall of the three-jaw chuck, and a spring is fixedly connected between the first disk and the second disk.
[0006] Several circular holes are opened on the right side of the second disc. A support plate and a first dustproof box are fixedly connected to the left side of the top of the base. A second dustproof box is fixedly connected to the top of the support plate. A fan is installed inside the second dustproof box. An air supply pipe is fixedly connected to the air blowing end of the fan. The other end of the air supply pipe is connected to the inside of the second disc.

[0007] Preferably, the drive structure includes a motor fixed to the bottom of the inner cavity of the first dustproof box, a first bevel gear fixedly connected to the output end of the motor, and a second bevel gear fixedly connected to one end of the rotating shaft, wherein the first bevel gear and the second bevel gear mesh with each other.
[0008] Preferably, a collection box is fixedly connected to one end of the top of the base, and one end of the collection box is fixedly connected to one side of the fixing plate.
[0009] Preferably, a bracket is fixedly connected to the top of the base, the bracket is located between the first dustproof box and the second dustproof box, and the interior of the bracket is fixedly connected to the surface of the air supply pipe.
[0010] Preferably, the diameters of the first and second disks are the same as the diameter of the inner hole of the three-jaw chuck, and the surface of the second disk is slidably connected to the interior of the three-jaw chuck.
[0011] Preferably, the gas supply pipe is a retractable flexible hose, and its extension length is greater than the movable distance between the first disc and the second disc.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] In this invention, the first disc, the second disc, and the spring allow the second disc to move outward after the pin has been processed, thanks to the elastic force of the spring.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4As shown, a centrifuge horizontal rotor pin clamping fixture structure includes a base 1, a fixing plate 2 fixedly connected to the top of the base 1, a fixing disk 3 rotatably connected to one side of the fixing plate 2, and a rotating shaft 17 fixed to the left side of the fixing disk 3. The other end of the rotating shaft 17 passes through the fixing plate 2 and is rotatably connected to its interior. The rotating shaft 17 is hollow to facilitate the entry of subsequent pipes. A three-jaw chuck 5 is bolted to the other side of the fixing disk 3. The three-jaw chuck 5 can be forceped by an external wrench, allowing the three jaws to move in the same or opposite directions to clamp and fix the pin. The interior of the three-jaw chuck 5 is respectively provided with a first disc. 6 and the second disc 7. The first disc 6 is fixedly connected to the inner wall of the three-jaw chuck 5. The diameters of the first disc 6 and the second disc 7 are the same as the diameter of the inner hole of the three-jaw chuck 5, and the surface of the second disc 7 is slidably connected to the inside of the three-jaw chuck 5. When the horizontal rotor is being processed, debris will be generated. The arrangement of the first disc 6 and the second disc 7 prevents a large amount of debris from splashing into the inside of the three-jaw chuck 5. A spring 8 is fixedly connected between the first disc 6 and the second disc 7. Several circular holes 9 are opened on the right side of the second disc 7, and the circular holes 9 are evenly distributed in a ring. A support plate 10 and a first dustproof box 4 are fixedly connected to the left side of the top of the base 1. A second dustproof box 11 is fixedly connected to the top of the base 1. A collection box 16 is fixedly connected to one end of the top of the base 1, and one end of the collection box 16 is fixedly connected to one side of the fixed plate 2. When the horizontal rotor is being processed, a large amount of debris is generated. The collection box 16 can collect most of the debris for centralized processing, thereby reducing the workload of the workers. A fan 13 is installed inside the second dustproof box 11. An air supply pipe 14 is fixedly connected to the blowing end of the fan 13. The other end of the air supply pipe 14 passes through the fixed plate 2 and extends into the interior of the three-jaw chuck 5. A bracket 15 is fixedly connected to the top of the base 1. The bracket 15 is located between the first dustproof box 4 and the second dustproof box 5. Between the two dust boxes 11, and the inside of the bracket 15 is fixedly connected to the surface of the air supply pipe 14. The bracket 15 provides auxiliary support for the air supply pipe 14, making the air supply pipe 14 more stable when conveying airflow. The air supply pipe 14 is a telescopic hose, and its extension length is greater than the movement distance between the first disc 6 and the second disc 7. With this design, when the horizontal rotor pin is relatively long, the telescopic setting of the air supply pipe 14 can push the air supply pipe 14 backward, so as not to affect the subsequent processing of the horizontal rotor pin. The other end of the air supply pipe 14 is connected to the inside of the second disc 7. The first dust box 4 is equipped with a drive structure 12.
[0021] The drive structure 12 includes a motor 121 fixed at the bottom of the inner cavity of the first dustproof box 4. The output end of the motor 121 is fixedly connected to a first bevel gear 122, and one end of the rotating shaft 17 is fixedly connected to a second bevel gear 123. The first bevel gear 122 and the second bevel gear 123 mesh with each other. With the setting of the drive structure 12, after the worker has fixed the horizontal rotor pin to be processed, the motor 121 can be turned on to drive the first bevel gear 122 to rotate. Then, through the meshing between the first bevel gear 122 and the second bevel gear 123, the rotating shaft 17 and the three-jaw chuck 5 can be driven to rotate, and then the horizontal rotor pin can be processed.
[0022] It is worth noting that the technical features such as the three-jaw chuck 5 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.
[0023] Working principle: When the horizontal rotor pin needs processing, the operator can first fix it using the three-jaw chuck 5. After fixing, the motor 121 is turned on to drive the first bevel gear 122 to rotate. Then, through the meshing between the first bevel gear 122 and the second bevel gear 123, the rotating shaft 17 can be rotated. The rotating shaft 17 can then drive the fixed plate 3 and the three-jaw chuck 5 to rotate, and drive the pin on the three-jaw chuck 5 to rotate. Subsequently, the pin is ground and cut by external processing equipment. During the processing, the blower 13 is turned on. Airflow is delivered to the surface of the second disc 7 through the air supply pipe 14 via the air blowing end. Then, the airflow can be evenly distributed inside the three-jaw chuck 5 through the round hole 9 on the surface of the second disc 7. This can blow out a large amount of debris inside the three-jaw chuck 5. When the long horizontal rotor pin is fixed, it will squeeze the second disc 7 and the spring 8 backward. After the horizontal rotor pin is processed, the pin is removed. Then, the elastic force of the spring 8 can push the second disc 7 forward, thereby squeezing out the debris remaining on the inner wall of the three-jaw chuck 5. This can reduce the trouble of subsequent cleaning.
