[0025] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 , Figure 2 , Figure 3 A dividing chuck fixture includes a flange seat 1, a connecting seat 2 rotatably connected to the end face of the flange seat 1, and a clamping seat 4 fixedly mounted on the end face of the connecting seat 2 by bolts. The clamping seat 4 has two oil guide channels 15 inside, a hydraulic rod 5 threadedly mounted to one end of each oil guide channel 15, and a clamping block 6 fixedly connected to the telescopic end of the hydraulic rod 5. One end of the oil guide channel 15 communicates with the interior of the hydraulic rod 5. The side surface of the connecting seat 2 has graduations, a connecting cavity 16 is provided inside the connecting seat 2, and two oil guide holes are provided on the end face of the connecting seat 2. 8. A first oil guide pipe 7 is provided at one end of the oil guide channel 15. The first oil guide pipe 7 is inserted into the oil guide hole 8. A second oil guide pipe 12 is fixedly connected to the end face of the flange seat 1. The second oil guide pipe 12 communicates with the inside of the connecting cavity 16. The clamp can be conveniently installed at a designated position using the flange seat 1. Since the clamping seat 4 is fixedly installed at one end of the connecting seat 2 by bolts, and the hydraulic rod 5 is threaded on the inner wall of the clamping seat 4, the composition structure of the clamp can be flexibly assembled and disassembled, which is convenient for maintenance and replacement, and its practicality is effectively improved.

[0027] Reference Figure 3 The flange seat 1 has a mounting hole on its inner end face, and a pressure sensor 14 (MIK-P300) is fixedly installed inside the mounting hole. The detection end of the pressure sensor 14 is placed inside the connecting cavity 16. The connecting cavity 16 inside the connecting seat 2 is connected to the inside of the hydraulic rod 5 through the oil guide hole 8, the first oil guide pipe 7, and the oil guide channel 15. During the clamping process, the hydraulic oil pressure inside the connecting cavity 16 is detected by the pressure sensor 14, which can detect the hydraulic oil pressure inside the hydraulic rod 5, thereby detecting the clamping force of the hydraulic rod 5. This allows the clamp to detect the clamping force in real time, effectively improving both functionality and practicality.

[0028] Reference Figure 2 , Figure 3A rotating base is fixedly connected to the inner wall of flange seat 1, and a linkage shaft 13 is rotatably installed in the mounting hole of the rotating base. A gear 17 is fixedly connected to one end of the linkage shaft 13. A gear ring 3 is fixedly connected to the inner wall of connecting seat 2. The gear 17 meshes with the gear ring 3. A worm gear 11 is fixedly installed to one end of the linkage shaft 13. A worm 10 is provided on one side of the worm gear 11. The worm 10 meshes with the worm gear 11. A motor 9 is fixedly installed on the end face of flange seat 1. One end of the worm 10 is connected to the rotating shaft of the motor 9. The end is fixedly connected, wherein when the clamping seat 4 is rotated, the motor 9 is started, and the motor 9 drives the worm 10 to rotate. Since the worm 10 is meshed with the worm wheel 11, the worm wheel 11 rotates synchronously with the gear 17 through the linkage shaft 13. The gear 17 is meshed with the gear ring 3, and the gear ring 3 is fixedly connected to the inner wall of the connecting seat 2. The clamping seat 4 is fixedly installed on the end face of the connecting seat 2 by bolts. Therefore, the rotation of the motor 9 can effectively drive the clamping seat 4 to rotate, ensuring that the clamped workpiece can be precisely positioned.

[0029] Working principle: In use, first install the fixture in the designated position, then place the workpiece to be processed between the two clamping blocks 6. Next, use the external hydraulic drive structure to inject hydraulic oil into the connecting cavity 16. Since the connecting cavity 16 is connected to the hydraulic rod 5 through the oil guide hole 8, the first oil guide pipe 7, and the oil guide channel 15, the two hydraulic rods 5 can be extended when hydraulic oil is injected, thereby bringing the two clamping blocks 6 closer together, thus enabling a firm clamping operation on the workpiece. During the clamping process, the pressure sensor 14 can be used to detect the hydraulic oil pressure inside the connecting cavity 16, which can detect the pressure of the hydraulic oil. The hydraulic oil pressure inside the hydraulic rod 5 can detect the clamping force of the hydraulic rod 5, enabling the fixture to detect the clamping force in real time. When the position of the workpiece needs to be adjusted, the motor 9 is started, and the motor 9 drives the worm gear 10 to rotate. Since the worm gear 10 is meshed with the worm wheel 11, the worm wheel 11 rotates synchronously with the gear 17 through the linkage shaft 13. The gear 17 is meshed with the gear ring 3, and the gear ring 3 is fixedly connected to the inner wall of the connecting seat 2. The clamping seat 4 is fixedly installed on the end face of the connecting seat 2 by bolts. Therefore, the rotation of the motor 9 can effectively drive the clamping seat 4 to rotate, ensuring that the clamped workpiece can be accurately positioned.
