[0002] Tool setting is a critical process in CNC machining. The accuracy of tool setting directly affects the machining quality and production efficiency of parts. With the rapid development of CNC machining technology, the requirements for machining accuracy and surface quality of parts are getting higher and higher. The traditional manual tool setting method can no longer meet the needs of modern machining.

[0003] Existing CNC machining tool setting devices have many obvious technical defects: most of them adopt manual adjustment, which has low adjustment accuracy, large error, and the adjustment process is cumbersome, time-consuming and labor-intensive; some devices adopt automatic adjustment, but lack real-time error detection and correction functions, and cannot eliminate machining errors caused by factors such as tool wear and thermal deformation, resulting in unstable machining accuracy.

[0004] Most devices can only achieve tool setting adjustment in a single dimension, and cannot simultaneously meet the high-precision tool setting requirements in both the radial and axial directions; moreover, they lack tool running status monitoring functions, making it impossible to detect tool wear and breakage in a timely manner, which can easily lead to machining scrap and equipment damage. In addition, existing devices have complex structures, are inconvenient to install and maintain, have poor versatility, and are difficult to adapt to different types of CNC machining tools.

[0005] Therefore, developing an online real-time detection and correction device for tool setting errors with high adjustment precision, real-time error detection and correction capability, and tool condition monitoring function is a technical problem that urgently needs to be solved in this field.

Working principle: Step 1: Device installation and tool clamping 12: The device is fixedly installed in the predetermined position on the CNC machining tool via the base plate 1, ensuring a secure installation; the tool 12 is inserted into the internal cavity of the tool holder 11, and the locking screw on the tool holder 11 is tightened to securely fix the tool 12 to the tool holder 11; check whether all connections are secure and without looseness; check whether the threaded rod 6 and the threaded rod 8 rotate smoothly without jamming; check whether all sensors are properly connected and the signal transmission is stable; after confirming that all components of the device are in good condition, prepare for the tool setting operation. Step 2: Adjustment and error correction of the radial position of tool 12: Adjust the radial position of the tool 12 according to the processing requirements; insert the external drive tool into the drive slot at the end of the threaded rod 8 and rotate the threaded rod 8; the rotation of the threaded rod 8 drives the moving plate 9 to move horizontally, and the moving plate 9 drives the motor 10, the tool holder 11 and the tool 12 to move horizontally synchronously; the tool holder 11 drives the adjusting plate 13 and the slide rod 14 to move horizontally synchronously along the slide groove of the limiting plate 15 to ensure that the movement is smooth and without shaking; during the movement, the radial displacement sensor 18 detects the lateral displacement of the moving plate 9 in real time and transmits the displacement signal to the control system; when the radial position of the tool 12 is close to the target position, the control system calculates the error between the actual position and the target position according to the signal fed back by the radial displacement sensor 18, and automatically controls the drive device to fine-tune the rotation angle of the threaded rod 8 until the radial position of the tool 12 reaches the target accuracy, thus completing the correction of the radial tool setting error; Step 3: Adjustment and error correction of the axial position of tool 12: Adjust the axial position of the tool 12 according to the processing requirements; rotate the threaded rod 6, which rotates relative to the top plate 3, driving the horizontal plate 5 and the frame 4 to move up and down along the axis of the support rod 2; the frame 4 drives the entire horizontal adjustment assembly and the tool 12 to move vertically in sync; during the movement, the axial displacement sensor 19 detects the vertical displacement of the frame 4 relative to the displacement plate 20 in real time and transmits the displacement signal to the control system; when the axial position of the tool 12 approaches the target position, the control system calculates the error between the actual position and the target position based on the signal fed back by the axial displacement sensor 19, and automatically controls the drive device to fine-tune the rotation angle of the threaded rod 6 until the axial position of the tool 12 reaches the target accuracy, thus completing the correction of the axial tool setting error; Step 4: Monitoring the operating status of tool 12: The motor 10 is started, which drives the tool holder 11 and the tool 12 to rotate at high speed to prepare for machining. During the rotation of the tool 12, the L-shaped rod 16 remains stationary with the adjusting plate 13. The vibration sensor 17 detects the vibration signal generated by the rotation of the tool 12 in real time and transmits the vibration signal to the control system. The control system analyzes the vibration signal to determine the wear, runout, and breakage of the tool 12. When the vibration signal exceeds the preset threshold, the control system issues an alarm signal to prompt the operator to replace the tool 12 or perform maintenance in time to avoid a decrease in machining quality or equipment damage. Step 5: Real-time monitoring and dynamic correction of the processing: During the machining process, the radial displacement sensor 18 and the axial displacement sensor 19 continuously monitor the radial and axial positions of the tool 12 in real time, while the vibration sensor 17 continuously monitors the vibration state of the tool 12 in real time. When the tool 12 shifts position due to wear, thermal deformation, or external force, the control system calculates the position error in real time based on the signals fed back by the sensors and automatically controls the rotation of the thread rod 6 and the thread rod 8 to dynamically correct the position of the tool 12 and ensure machining accuracy. When the tool 12 is damaged or severely worn, the control system immediately issues a stop signal to stop machining and avoid producing scrap. Step Six: Equipment Maintenance and Care Regularly check the thread wear of threaded rod 6 and threaded rod 8, apply grease to ensure smooth rotation; regularly check the fit between slide rod 14 and limit plate 15, clean debris from the slide groove to ensure smooth sliding; regularly calibrate the detection accuracy of each sensor to ensure accurate and reliable detection results; regularly check the tightness of each connecting bolt, tighten them promptly if any are found to be loose; regularly clean chips and oil stains from the surface of the device to keep the device clean and dry.
