[0034] Working principle: This invention rotates the locking disc 24, causing the locking frame 251 to move closer to the turret disc 23. During the movement of the locking frame 251, the locking block 255 locks and fixes both sides of the tool holder 271, and the pressure block 258 presses and fixes one end of the tool holder 271, thereby limiting the tool holder 271 in different directions and ensuring the stability of the tool holder 271. Furthermore, the axial position of the locking disc 24 is limited by the limiting block 235, and the locking nut 237 limits and fixes both sides of the limiting block 235, ensuring the axial position of the locking disc 24. The stability of the directional and circumferential positions prevents the locking disc 24 from rotating on its own. Similarly, when the tool 27 needs to be disassembled for maintenance, first loosen the locking nut 237, then rotate the locking disc 24 in the opposite direction to move the locking mechanism 25 away from the turret disc 23, and then remove the tool 27 from the mounting slot 231. Compared with the prior art, this embodiment allows multiple tools 27 to be locked and fixed simultaneously by the locking disc 24 and the locking mechanism 25, enabling the simultaneous installation and removal of multiple tools 27. The installation and removal of the tools 27 are more convenient and conducive to the maintenance of the machine tool.
