Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example

[0026] See also Figures 1 to 6 , is an embodiment of the present invention, which provides a technical solution: a machine tool spindle brake device with a monitoring function, comprising

[0027] Pressure gauge 1, hydraulic valve block 2, adjustable mounting bracket 3, oil pressure pipeline 4 and hydraulic valve 5. The hydraulic valve block 2 is mounted on the machine tool through the adjustable mounting bracket 3. The pressure gauge 1 is mounted on the hydraulic valve block 2. The hydraulic valve block 2 and the oil pressure pipeline 4 are connected through the hydraulic valve 5. The model of the pressure gauge 1 is PT124B-10Mpa.

[0028] and a monitoring system, including a hydraulic brake system module, a pressure monitoring module, a signal processing and feedback module, a machine tool shutdown control module and a user interface module.

[0029] The hydraulic brake system module is used to provide the hydraulic power required for braking and realize the braking action by controlling the flow of hydraulic oil. It includes a hydraulic pump, 4 hydraulic pipelines and a hydraulic cylinder. It is designed with a brake input port to receive the brake command and transmit it to the hydraulic cylinder;

[0030] The pressure monitoring module is used to monitor the oil pressure changes in the brake hydraulic pipeline in real time. The pressure monitoring module consists of a pressure gauge 1 and a signal processing circuit. The pressure gauge 1 is installed on the hydraulic pipeline behind the brake input port and can accurately measure the oil pressure. When the oil pressure is abnormal, the pressure gauge 1 sends an electrical signal to the system through the signal processing circuit.

[0031] The signal processing and feedback module is used to receive the electrical signal sent by the pressure monitoring module and perform processing and judgment. The signal processing and feedback module includes an alarm module, a signal amplification circuit and a microprocessor module. The microprocessor has a built-in preset oil pressure threshold. When the received oil pressure signal is lower or higher than the threshold, it is judged that the brake is damaged; at the same time, a stop command is sent to the machine tool through the alarm circuit.

[0032] The machine tool shutdown control module is used to receive the shutdown command sent by the signal processing and feedback module and execute the shutdown operation. The machine tool shutdown control module includes a machine tool control module and an execution module (such as a motor, solenoid valve, etc.), which can quickly respond to the shutdown command, shut down the power supply or power source of the machine tool, and stop the machine tool from running.

[0033] The user interface module is used to provide users with intuitive display and alarm information of the brake status. The user interface module includes a display module, an indicator light and an alarm buzzer. The display screen can display the oil pressure value of the brake hydraulic pipeline in real time; when the brake is damaged, the indicator light will light up or the alarm buzzer will sound to remind the user to deal with it in time;

[0034] The specific workflow of the monitoring system:

[0035] 1. When the machine tool is operating normally, the hydraulic brake system module provides stable hydraulic power to keep the brake in a normal state;

[0036] 2. The pressure monitoring module monitors the oil pressure changes in the brake hydraulic pipeline in real time, and sends the measured value to the signal processing and feedback module through the signal processing circuit;

[0037] 3. The signal processing and feedback module processes and judges the received oil pressure signal. When it is judged that the brake is damaged, it sends a shutdown command to the machine tool shutdown control module;

[0038] 4. After receiving the shutdown command, the machine tool shutdown control module executes the shutdown operation and shuts down the power supply or power source of the machine tool;

[0039] 5. The user interface module provides users with intuitive display of brake status and alarm information, reminding users to handle it in time;

[0040] Through the design of the above system framework, real-time monitoring and effective protection of the machine tool spindle brake device can be achieved, thereby improving the safety and reliability of the machine tool.
