[0021] 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.

[0022] Example

[0023] like Figure 1-6As shown in the figure, an embodiment of the present invention provides a machine tool chuck, including a mounting base 1. A threaded post 2 is fixedly connected to the middle of the mounting base 1. A disc 3 is fixedly connected to one end of the threaded post 2. The surface of the disc 3 has three through-holes 4 arranged in a circumferential array. A slider 5 is slidably installed in each of the three through-holes 4. Three fixing blocks 6 are fixedly arranged in a circumferential array on the surface of the disc 3. A T-shaped guide rod 7 is fixed to the surface of each of the three fixing blocks 6. The three sliders 5 are slidably sleeved on the surface of the corresponding T-shaped guide rod 7. One end of each of the three sliders 5 is... Three locking blocks 8 are installed, and all three locking blocks 8 slide against the surface of the disc 3. The other ends of the three sliders 5 are rotatably connected to the connecting rods 9 via pins. The surface of the threaded column 2 is slidably fitted with a sleeve 10. One end of each of the three connecting rods 9 is rotatably connected to the surface of the sleeve 10 via pins. The surface of the threaded column 2 is threadedly connected with a threaded tube 11. The surface of the threaded tube 11 is fixed with three connecting blocks 12 in a circumferential array. The surface of the sleeve 10 is provided with an annular groove 13. One end of each of the three connecting blocks 12 is fitted and slidably installed in the annular groove 13.

[0024] In use, the mounting base 1 is fixed on the machine tool. The surface of the mounting base 1 has mounting holes 16 arranged in a circumferential array, which can be easily fixed to the machine tool with bolts or screws. When it is necessary to clamp and fix the rod-shaped part, the threaded tube 11 can be rotated. The surface of the threaded tube 11 is fixed with a turntable 17, which makes it easier for the operator to rotate the threaded tube 11. The threaded tube 11 rotates towards the mounting base 1, which drives the three connecting blocks 12 to rotate towards the mounting base 1. The three connecting blocks 12 drive the sleeve 10 to move towards the mounting base 1. The sleeve 10 drives the three connecting rods 9 to move. The three connecting rods 9 drive the three sliders 5 to move towards the center of the disc 3. The three sliders 5 drive the three locking blocks 8 to move towards the center of the disc 3. In this way, the rod-shaped part can be clamped and fixed. The operation is simple and convenient, the manufacturing cost is low, and it can better meet the needs of some special users in the market.

[0025] like Figure 1 and Figure 6 As shown, in some embodiments, the locking block 8 and the slider 5 are connected by screws, which makes it easier to replace the locking block 8. The surface of the locking block 8 is fixedly connected with anti-slip rubber pads 14, which can play a good anti-slip role, thereby clamping the parts more firmly and improving the use effect. The surface of the mounting base 1 is fixed with three crossbars 15 in a circumferential array. One end of each of the three crossbars 15 is fixedly connected to the surface of the disc 3 in order to improve the structural stability of the mounting base 1 and the disc 3.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
