[0002] CNC lathes are among the most widely used CNC machine tools, mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. In order to assist in the stable adjustment and replacement of precision boring tools when used inside CNC lathes, an adjustable precision boring tool and adjustment method for CNC lathes are needed.

Then, the tension spring is used to move the inner wall of the limit ring away from the side of the protrusion, thereby assisting the separation of the tool body from the tool holder disk and assisting the replacement and mounting of the tool body.

[0018] The present invention has the following beneficial effects:

Then, an electric telescopic rod is used to move the adjustment plate, and an electric telescopic rod is used to move the arc plate until the inner wall of the arc plate aligns with the inner wall of the tool body. This assists in the docking of the infrared signal receiver and the infrared signal transmitter. The electromagnet and the fixed magnet ring are used for docking and adsorption, thereby assisting the device in adjusting the tool.

[0020] 2. The CNC lathe uses an adjustable precision boring tool and adjustment method. The adjustment gear drives the rotating ring to rotate through the cam gear group, and the electric push rod drives the rotating ring to move through the fixed ring, thereby assisting the separation of the docking ring and the docking block. When the electromagnet plate is de-energized, it assists the arc plate to drive the tool body to move stably.

[0021] 3. The CNC lathe uses an adjustable precision boring tool and adjustment method. The inner wall of the arc plate is connected to the tool body at the bottom of the tool holder, thereby closing the first solenoid valve tube and opening the second solenoid valve tube. The second solenoid valve tube is used to assist in the exhaust of air inside the cylinder. Then, the tension spring is used to move the inner wall of the limit ring away from the side of the protrusion, thereby assisting the separation of the tool body from the tool holder and assisting in the replacement and mounting of the tool body.

[0040] In a preferred embodiment, the following steps are included:

[0041] S1: First, the motor 3 rotates through the circular plate 4, thereby driving the tool body 12 to process the required area. Then, the electric telescopic rod 24 drives the adjusting plate 26 to move, and the electric telescopic rod 27 drives the arc plate 28 to move until the inner wall of the arc plate 28 aligns with the inner wall of the tool body 12, thereby assisting the infrared signal receiver 16 to align with the infrared signal transmitter.

Then, electric telescopic rod 24 moves the adjusting plate 26, and electric telescopic rod 27 moves the arc-shaped plate 28 until the inner wall of the arc-shaped plate 28 aligns with the inner wall of the tool body 12. This facilitates the docking of the infrared signal receiver 16 with the infrared signal transmitter.

Finally, motor 22 drives the adjusting gear 23, which in turn drives the rotating ring 20 through the toothed gear assembly 21. The electric push rod 18 drives the rotating ring 20 to move through the fixed ring 19, thereby assisting the separation of the docking ring 14 and the docking block 43.

A fixed magnet ring (17) is fixedly mounted on the top and bottom of the inner wall of the tool body (12). An electromagnet plate (29) is fixedly mounted on the top and bottom of the arc plate (28). An infrared signal transmitter is fixedly mounted on the inner wall of the arc plate (28), and the infrared signal transmitter is electrically connected to the infrared signal receiver (16).

8. The adjustment method for an adjustable precision boring tool for a CNC lathe according to claim 7, characterized in that, Includes the following steps: S1: First, the motor (3) is used to rotate through the circular plate (4), thereby using the circular plate (4) to drive the tool body (12) to process the required area. Then, the electric telescopic rod (24) is used to drive the adjustment plate (26) to move, and the electric telescopic rod (27) is used to drive the arc plate (28) to move until the inner wall of the arc plate (28) is connected with the inner wall of the tool body (12), thereby assisting the infrared signal receiver (16) to connect with the infrared signal transmitter, and using the electromagnet plate (29) and the fixed magnet ring (17) to connect and attract, thereby assisting the device to adjust the tool. S2: Then, the motor three (22) drives the adjusting gear (23) to rotate, thereby the adjusting gear (23) drives the rotating ring (20) to rotate through the tooth group (21), and the electric push rod (18) drives the rotating ring (20) to move through the fixed ring (19), thereby assisting the separation of the docking ring (14) and the docking block (43), and controlling the electromagnet plate one (11) to be de-energized, thereby assisting the arc plate (28) to drive the tool body (12) to move stably; S3: Finally, the inner wall of the arc plate (28) is connected with the tool body (12) at the bottom of the tool holder disk (31) to close the first solenoid valve tube (42) and open the second solenoid valve tube (32). The second solenoid valve tube (32) is used to assist the exhaust inside the cylinder (34). Then, the tension spring (35) is used to drive the inner wall of the limit ring (39) away from the side of the protrusion (40), thereby assisting the separation of the tool body (12) from the tool holder disk (31) and assisting the replacement of the tool body (12).
