[0004] The purpose of this invention is to provide a high-efficiency and stable hydraulically driven indexing chuck machine tool that can perform real-time monitoring and active protection of the hydraulic circuit, with high stability and safety.
[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0018] In summary, the beneficial technical effects of this utility model are as follows:
[0019] This invention allows for the closure of the first solenoid valve during workpiece clamping, ensuring a stable pressure for the hydraulic oil in the hydraulic rod, connecting cavity, first guide oil pipe, second guide oil pipe, and detection box. Simultaneously, a pressure sensor monitors the oil pressure inside the detection box in real time, enabling real-time monitoring of the clamping force. The pressure sensor transmits the monitored data to a pressure alarm. If the clamping loosens during processing, the hydraulic oil pressure inside the detection box drops, triggering an alarm and energizing the coil of a control relay. This activates the relay to close the working circuit of the second solenoid valve, allowing it to promptly cut off the oil flow in the second guide oil pipe, preventing backflow of hydraulic oil from the hydraulic rod, thus preventing a continuous decrease in clamping force and ultimately preventing workpiece detachment. This structure enables real-time monitoring of the machine tool's hydraulic circuit, and can promptly cut off the end of the oil circuit in case of leakage, preventing workpiece detachment. Safety, operational stability, and practicality are all effectively improved. Attached Figure Description

[0027] The method of this utility model will be further described in detail below with reference to the accompanying drawings.
[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6A high-efficiency and stable hydraulically driven indexing chuck machine tool includes a bed 1, a base 22 fixedly installed in the mounting position of the bed 1, a clamping seat 7 rotatably connected to one end of the base 22, a communicating cavity 23 provided inside the base 22, and a hydraulic rod 18 fixedly installed on the symmetrical inner wall of the clamping seat 7, one end of the hydraulic rod 18 connected to a second oil guide pipe 19, the other end of the second oil guide pipe 19 communicating with the inside of the communicating cavity 23, a second solenoid valve 20 fixedly installed in the pipe of the second oil guide pipe 19, and a first oil guide pipe 11 fixedly connected to the end face of the base 22, one end of the first oil guide pipe 11 communicating with the inside of the communicating cavity 23, the second... A detection box 14 is fixedly installed in the oil guide pipe 11. A pressure sensor 15 (MIK-P300) is fixedly installed on the side surface of the detection box 14. A pressure alarm 16 and a control relay 17 are fixedly installed on the outer surface of the bed 1. A ring-shaped conductive connector 24 is provided on the end face of the base 22. The pressure sensor 15 is electrically connected to the pressure alarm 16. The buzzer inside the pressure alarm 16 is connected in parallel with the signal receiving end of the control relay 17. The control relay 17 is electrically connected to the second solenoid valve 20. The ring-shaped conductive connector 24 is electrically connected to the second solenoid valve 20. A pressure sensor 15 (MIK-P300) is fixedly installed on the inner side of the bed 1. The oil reservoir 9 has one end of the first oil guide pipe 11 connected to its interior. The first oil guide pipe 11 contains a first solenoid valve 12 and a hydraulic pump 13. When clamping a workpiece, the first solenoid valve 12 can be closed, ensuring a stable pressure for the hydraulic oil in the hydraulic rod 18, connecting cavity 23, first oil guide pipe 11, second oil guide pipe 19, and detection box 14. Simultaneously, a pressure sensor 15 monitors the oil pressure inside the detection box 14 in real time, allowing for real-time monitoring of the clamping force. The pressure sensor 15 also transmits the monitored data to the pressure alarm 16. During the processing, when clamping... If the hydraulic system becomes loose, the hydraulic oil pressure inside the detection box 14 will drop. At this time, the pressure alarm 16 will sound an alarm and simultaneously energize the coil of the control relay 17. This will cause the control relay 17 to close the working circuit of the second solenoid valve 20, allowing the second solenoid valve 20 to cut off the oil circuit of the second oil guide pipe 19 in a timely manner. This will prevent the hydraulic oil inside the hydraulic rod 18 from flowing back, prevent the clamping force from continuously decreasing, and thus prevent the workpiece from falling off. This structure can monitor the hydraulic circuit of the machine tool in real time. Once an oil circuit leak occurs, it can cut off the end oil circuit in a timely manner to prevent the workpiece from falling off. Safety, working stability, and practicality are all effectively improved.
[0029] Reference Figure 1 , Figure 6A power mechanism 10 is fixedly installed on the end face of the base 22. The output end of the power mechanism 10 is fixedly connected to a linkage shaft 21. The other end of the linkage shaft 21 is fixedly connected to the end face of the clamping seat 7. Two first linear modules 3 are fixedly installed on the upper surface of the bed 1. A second linear module 4 is fixedly installed on the moving end of the two first linear modules 3. A third linear module 5 is fixedly installed on the moving end of the second linear module 4. A tool holder 6 is fixedly installed on the moving end of the third linear module 5. A CNC control center 8 is fixedly installed on the outer surface of the bed 1. A housing 2 is installed on the outside of the bed 1. The power mechanism 10 can drive the linkage shaft 21 to rotate, and the linkage shaft 21 can drive the clamping seat 7 to rotate, thereby driving the workpiece to rotate. Then, the first linear modules 3, the second linear modules 4, and the third linear modules 5 are used to move the tool holder 6 and the tool installed on the tool holder 6 in the X, Y, and Z axes, ensuring that the machining operation can be carried out stably and orderly.
[0030] Working principle: In use, first place the machine tool in the designated position, then place the workpiece to be processed between the two hydraulic rods 18. Next, start the hydraulic pump 13 to inject hydraulic oil into the hydraulic rods 18. At this time, the two hydraulic rods 18 extend to effectively clamp and fix the workpiece. After clamping, close the first solenoid valve 12 to ensure that the hydraulic oil inside the hydraulic rods 18, connecting cavity 23, first oil guide pipe 11, second oil guide pipe 19, and detection box 14 is at a stable pressure value, allowing for processing. During processing, the power mechanism 10 drives the linkage shaft 21 to rotate, which in turn drives the clamping seat 7 to rotate, thereby rotating the workpiece. Then, the first linear module 3, second linear module 4, and third linear module 5 are used to rotate the tool holder 6 and the workpiece mounted on the tool holder 6. The cutting tool moves along the X, Y, and Z axes to ensure stable and orderly machining operations. During machining, pressure sensor 15 monitors the oil pressure inside the detection box 14 in real time, allowing for real-time monitoring of the clamping force. Simultaneously, pressure sensor 15 transmits the monitored data to pressure alarm 16. If the clamping becomes loose during machining, the hydraulic oil pressure inside the detection box 14 will drop. At this time, pressure alarm 16 will sound an alarm and simultaneously energize the coil of control relay 17, controlling relay 17 to close the working circuit of second solenoid valve 20. This allows second solenoid valve 20 to promptly cut off the oil path of second oil guide pipe 19, preventing backflow of hydraulic oil inside hydraulic rod 18, preventing a continuous decrease in clamping force, and thus preventing the workpiece from falling off.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
