Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1 to 3 As shown, a spindle chuck assembly / disassembly device includes a rolling mill 1 and a fixing plate 2. The fixing plate 2 is fixedly installed on the top of the rolling mill 1. A groove 19 is provided on the fixing plate 2, and a limit block 16 is slidably installed in the groove 19. A connecting rod 17 is rotatably installed in the limit block 16. A connecting plate 18 is rotatably installed at one end of the connecting rod 17. A movable plate 3 is fixedly installed on the top of the connecting plate 18. The fixing plate 2 is provided with a drive assembly for driving the limit block 16 to move. Figure 2 and Figure 3 As shown, the drive assembly includes a cavity 20, which is opened in the fixed plate 2 and located on one side of the groove 19. A second electric push rod 15 is fixedly installed in the cavity 20. The output end of the second electric push rod 15 extends through one side of the cavity 20 into the groove 19 and is fixedly connected to the limiting block 16. A U-shaped plate 13 is fixedly installed on one side of the fixed plate 2. A roller 14 is rotatably installed in the U-shaped plate 13. A guide rod 12 fixed to the moving plate 3 is provided in the U-shaped plate 13.

[0021] More specifically, the operator can connect the second electric push rod 15 to the power supply and start it. The output shaft of the second electric push rod 15 will drive the limit block 16 to move. At this time, the two ends of the connecting rod 17 will rotate in the limit block 16 and the connecting plate 18 respectively. The moving plate 3 will move upward, and the moving plate 3 will drive the guide rod 12 to move upward. During the displacement, the guide rod 12 will always be pressed against the roller 14, which can drive the roller 14 to rotate and also ensure the stability of the vertical displacement of the moving plate 3.

[0022] A sliding plate 5 is slidably mounted on the movable plate 3. A drive motor 6 is fixedly mounted on the sliding plate 5. A rotating sleeve 7 is fixedly mounted on the output end of the drive motor 6. A rotating shaft 8 is inserted into the rotating sleeve 7. A fixed frame 9 and a support plate 10 are fixedly mounted on the sliding plate 5. One end of the rotating shaft 8 passes through the fixed frame 9 and the support plate 10 and is fixedly mounted with a clamp body 11. A U-shaped limiting plate 21 is slidably mounted inside the fixed frame 9. A pull plate 23 is fixedly mounted on the top of the U-shaped limiting plate 21. An insert plate 22 is inserted into the pull plate 23. The two ends of the insert plate 22 pass through the two sides of the fixed frame 9 respectively. A fixing component is provided inside the insert plate 22.

[0023] More specifically, during installation, the operator inserts one end of the rotating shaft 8 through the chuck body 11 and into the rotating sleeve 7. Then, the operator pulls down the plate 23, which causes the U-shaped limiting plate 21 to move downwards, placing it inside the rotating shaft 8. At this point, the rotating shaft 8 is limited, only able to rotate and unable to move up, down, left, or right. Next, the insert plate 22 is inserted into the fixing frame 9 and the pull plate 23. Under the rebound force of the spring 26, the spring 26 causes the spring block 24 to move upwards until one end of the spring block 24 moves to the outside and contacts one side of the fixing frame 9. At this point, the pull plate 23 and the U-shaped limiting plate 21 are fixed. The operator can then connect the drive motor 6 to power it and start it. The output shaft of the drive motor 6 will drive the rotating sleeve 7 to rotate, which in turn will drive the rotating shaft 8 to rotate, and the rotating shaft 8 will drive the chuck body 11 to rotate. like Figures 5 to 7 As shown, the two ends of the spring 26 are tightly welded to the bottom of the spring block 24 and the bottom of the slide groove 25, respectively, and one side of the spring block 24 is in contact with the side of the fixed frame 9 away from the rotating sleeve 7.

[0024] More specifically, this ensures the structural stability of the spring 26 and guarantees that the position of the insert plate 22 can be fixed when the spring block 24 is displaced to the outside.

[0025] like Figure 1 and Figure 8 As shown, the U-shaped limiting plate 21 extends into the rotating shaft 8, the rotating shaft 8 is rotatably connected to the U-shaped limiting plate 21, and the rotating shaft 8 is movably connected to the rotating sleeve 7.

[0026] More specifically, this ensures that the rotating shaft 8 can rotate within the U-shaped limiting plate 21 and that the rotating shaft 8 can move within the rotating sleeve 7.

[0027] like Figure 2 and Figure 3 As shown, a first electric push rod 4 is fixedly installed on the top of the movable plate 3. The output end of the first electric push rod 4 is fixedly connected to the slide plate 5, and the connecting rod 17 is set at an angle.

[0028] More specifically, this ensures that the output shaft of the first electric push rod 4 can drive the slide plate 5 to move, and ensures that the connecting rod 17 can rotate.

[0029] In summary: When using the chuck body 11, if it is necessary to disassemble it, the operator can press down on the spring block 24 by hand, so that the spring block 24 is retracted into the slide groove 25. At this time, the spring 26 will be compressed and contracted until the spring block 24 is completely inserted into the slide groove 25. Then, the operator can pull the insert plate 22, so that the insert plate 22 is completely removed from the fixed frame 9 and the pull plate 23. At this time, the pull plate 23 can be pulled up, so that the pull plate 23 drives the U-shaped limiting plate 21 to move upward. The U-shaped limiting plate 21 will move out of the rotating shaft 8 and into the fixed frame 9. Then, the operator can pull one end of the rotating shaft 8 out of the rotating sleeve 7, so that the rotating shaft 8 is completely removed from the chuck body 11. During installation, the worker inserts one end of the rotating shaft 8 through the clamp body 11 and into the rotating sleeve 7. Then, the worker pulls down the plate 23, which causes the U-shaped limiting plate 21 to move downwards, so that the U-shaped limiting plate 21 moves into the rotating shaft 8. At this time, the rotating shaft 8 will be limited, and the rotating shaft 8 can only rotate but cannot move up, down, left, or right. Then, the insert plate 22 is inserted into the fixing frame 9 and the pull plate 23. Under the action of the spring 26's rebound force, the spring 26 will cause the spring block 24 to move upwards until one end of the spring block 24 moves to the outside and is aligned with the fixing frame 9. When the side contacts the plate 23, the pull plate 23 will be fixed and the U-shaped limit plate 21 will also be fixed. The operator can connect the drive motor 6 to the power supply and start it. The output shaft of the drive motor 6 will drive the rotating sleeve 7 to rotate, the rotating sleeve 7 will drive the rotating shaft 8 to rotate, and the rotating shaft 8 will drive the chuck body 11 to rotate. When it is necessary to adjust the position of the chuck body 11, the first electric push rod 4 can be connected to the power supply and start it. The output shaft of the first electric push rod 4 will drive the slide plate 5 to move on the moving plate 3, thereby driving the chuck body 11 to move. When the height of the chuck body 11 needs to be adjusted, the operator can connect the second electric push rod 15 to the power supply and start it. The output shaft of the second electric push rod 15 will drive the limit block 16 to move. At this time, the two ends of the connecting rod 17 will rotate in the limit block 16 and the connecting plate 18 respectively. The moving plate 3 will move upward, and the moving plate 3 will drive the guide rod 12 to move upward. During the displacement, the guide rod 12 is always pressed against the roller 14, which can drive the roller 14 to rotate and also ensure the stability of the vertical displacement of the moving plate 3.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
