[0029] 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.

[0030] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a milling machine part clamping device, including a machining bed 1. Slider 3 is slidably connected to both sides of the interior of the machining bed 1. A support frame 2 is fixedly connected to the upper part of the slider 3. An installation frame 4 is installed on the upper part of the support frame 2. A connecting frame 5 is fixedly connected to the adjacent side of the installation frame 4. A fixing clamp 14 is installed inside the connecting frame 5. A through groove 16 is opened on one side of the fixing clamp 14. A rotating clamp 11 is rotatably connected inside the through groove 16. An electric push rod 6 is fixedly connected inside the installation frame 4. A ball sleeve 7 is fixedly connected to the output end of the electric push rod 6. A pulling component is rotatably connected inside the ball sleeve 7. The pulling component is used to rotate the rotating clamp 11 to clamp and fix the part.

[0031] The pulling assembly includes a ball 8, which is rotatably connected inside the ball sleeve 7. A pulling rod 9 is fixedly connected to one side of the ball 8. A rotating shaft 13 is fixedly connected to one end of the pulling rod 9. The outside of the rotating shaft 13 is rotatably connected to the inside of the rotating clamp 11. Rotating shafts 15 are fixedly connected to both sides of the inside of the fixed clamp 14. One end of the rotating clamp 11 is rotatably connected to the outside of one side of the rotating shaft 15. A rotating ring 10 is fixedly connected to one side of the pulling rod 9. The rotating ring 10 is rotatably connected to the outside of the rotating shaft 15 near the ball 8. A through groove 12 is opened on one side of the rotating clamp 11. The pulling rod 9 is rotatably connected to the inside of the through groove 12.

[0032] By activating the electric actuator 6, the internal piston rod extends and drives the ball sleeve 7, causing the ball 8 to rotate inside the ball sleeve 7. This causes the pull rod 9 to push the rotating clamp 11, causing the rotating ring 10 to rotate outside one side of the rotating shaft 15. The rotating shaft 13 rotates inside the rotating clamp 11, while the rotating clamp 11 rotates outside the other side of the rotating shaft 15 and inside the through groove 16. This causes the rotating clamp 11 to rotate closer to the fixed clamp 14 and clamp the part, thus achieving a tight clamping and fixing of the part and ensuring the stability of the workpiece position and the machining accuracy during the processing.

[0033] Reference Figures 2-4 The upper left and right sides of the support frame 2 are fixedly connected with insert blocks 19. The insert blocks 19 have slots 20 inside. The insert blocks 19 are engaged with the inside of the mounting frame 4. The inner left and right sides of the mounting frame 4 are provided with grooves 21. The inner wall of the grooves 21 is fixedly connected with a telescopic rod 22. One end of the telescopic rod 22 is fixedly connected with a block 24. The block 24 is slidably connected inside the slots 20 and the grooves 21. The telescopic rod 22 is sleeved with a spring 23. One end of the spring 23 is fixedly connected to the inner wall of the groove 21, and the other end of the spring 23 is fixedly connected to one side of the block 24.

[0034] Both sides of the support frame 2 are fitted with clamping plates 17, which are engaged inside the machining bed 1. The side of the clamping plate 17 furthest from the machine has an adjusting member 18 threadedly connected inside.

[0035] By pulling the mounting frame 4 upward, the insert block 19 blocks the movement of the locking block 24 as the mounting frame 4 moves, causing the locking block 24 to move and apply pressure to the telescopic rod 22 and spring 23, moving it out of the slot 20 and into the groove 21. This causes the spring 23 to generate a rebound force, thus separating the mounting frame 4 from the insert block 19 and completing the disassembly of the clamping structure. This enables quick and convenient installation and disassembly of the clamping structure, improving the applicability of the clamping device. By locking the clamping plate 17 in the groove of the machining bed 1 and rotating the adjusting member 18 until it abuts against the machining bed 1, the clamping plate 17 is fixed in its position, thus limiting the clamping mechanism and preventing it from moving during part processing, which would affect the processing effect and quality.

[0036] Working principle: When the device is needed, the electric actuator 6 is activated, which drives the ball sleeve 7 to move, causing the ball 8 to rotate and push the pull rod 9, causing the rotating ring 10 and the rotating shaft 13 to rotate, which pushes the rotating clamp 11 to rotate outside the rotating shaft 15 on one side. Finally, the rotating clamp 11 moves closer to the fixed clamp 14 to clamp the part, thus achieving a tight clamping and fixing of the part, ensuring the stability of the workpiece position and the machining accuracy during the processing. When the clamping structure is not suitable for some parts, the mounting frame 4 is pulled upward, causing the locking block 24 to move due to the obstruction of the insertion block 19, which applies pressure to the telescopic rod 22 and the spring 23, causing the locking block 24 to move out of the locking slot 20 and into the groove 21, separating the mounting frame 4 from the insertion block 19, completing the disassembly of the clamping structure. This enables quick and convenient installation and disassembly of the clamping structure, improving the applicability of the clamping device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
