[0030] The present utility model provides a large-diameter general automatic chuck with a middle through hole. Please refer to Figures 1-4 , including a frame 100, a chuck assembly 200, and a power component 300;

[0031] Please continue to refer to Figure 1 , the frame 100 as a connecting base frame;

[0032] Please continue to refer to Figures 1-4 , the chuck assembly 200 is connected to the frame 100, including a connecting frame 210 rotatably connected to the rear side of the frame 100, and a connecting cylinder 211 integrally formed and connected to the outside of the connecting frame 210, and the connecting cylinder 211 extends to the front side of the frame 100;

[0033] The outer side of the connecting cylinder body 211 is threadedly connected to the chuck 220. A plurality of jaws 221 are slidably connected to the chuck 220, and a disc frame 230 is rotatably connected inside the chuck 220;

[0034] A main rotating gear ring 212 is sleeved on the outer side of the connecting frame 210 (the main rotating gear ring drives the connecting frame to rotate on the machine frame), and a sub-rotating gear ring 232 is connected to the outer side of the disc frame 230 (the sub-rotating gear ring drives the disc frame to rotate inside the chuck). Thread grooves 222 are formed on the outer sides of the jaws 221, and a thread seat 231 adapted to the thread grooves 222 is connected to the outer side of the disc frame 230 (the jaws are slidably connected to the chuck. When the disc frame and the chuck rotate relative to each other, the jaws move horizontally along the outer side of the chuck under the action of the thread grooves and the thread seat, thereby realizing the clamping / loosening action);

[0035] Please continue to refer to Figures 1-3 , the power component 300 is connected to the outer side of the machine frame 100 to provide power and drive the chuck component 200 to move on the machine frame 100;

[0036] The power component 300 includes a first mounting frame 310 integrally formed and connected to the outer side of the machine frame 100. A first driving motor 320 is threadedly connected to the outer side of the first mounting frame 310. The output end of the first driving motor 320 is connected to a first gear 321 that meshes and drives with the main rotating gear ring 212;

[0037] Action 1:

[0038] The first driving motor 320 works, drives the first gear 321 to rotate, and then drives the connecting frame 210 connected to the main rotating gear ring 212 to rotate on the machine frame 100, realizing the overall rotation of the chuck 220;

[0039] The power component 300 further includes a second mounting frame 330 integrally formed and connected to the outer side of the machine frame 100. A second driving motor 320 is threadedly connected to the outer side of the second mounting frame 330. A clutch 341 is rotatably connected inside the second mounting frame 330. The clutch 341 is key-connected to the output end of the second driving motor 320.

[0040] Action 2:

[0041] The second driving motor 320 works, and the rotation driving force input of the second gear 341 is controlled in a timely manner through the engagement and separation of the clutch 341. When the clutch 341 is engaged, the rotation power of the second gear 341 is input to the sub-rotating gear ring 232 to ensure the rotation of the disc frame 230, thereby realizing the automatic loosening / clamping of the jaws 221. When the clutch 341 is separated, the rotation power mechanism of the second gear 341 is disconnected, without affecting the rotation of the entire chuck 220;

[0042] Working principle: When the utility model is in use, the first driving motor 320 drives the first gear 321 to rotate, causing the connecting frame 210 connected to the main rotating gear ring 212 to rotate on the machine frame 100, realizing the overall rotation of the chuck 220. At the same time, the second driving motor 320 operates, and the input of the rotational driving force of the second gear 341 is timely controlled by the engagement and separation of the clutch 341. When the clutch 341 is engaged, the rotational power of the second gear 341 is input to the auxiliary rotating gear ring 232 to ensure the rotation of the disc frame 230, thereby realizing the automatic loosening / clamping of the jaws 221. When the clutch 341 is separated, the rotational power mechanism of the second gear 341 is disconnected, without affecting the rotation of the entire chuck 220.

[0043] Although the present utility model has been described above with reference to the embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the features of the embodiments disclosed in the present utility model can be combined with each other in any way.
