[0026] like Figures 1-5As shown, a machine tool combination tool fixing structure includes a vertical plate base 1, a base 11 fixedly installed on the left side of the vertical plate base 1, a reinforcing frame 12 fixedly installed on the top of the base 11, the reinforcing frame 12 fixedly installed on the left side of the vertical plate base 1, a cleaning-type tool integration mechanism 2 and an idle protection mechanism 3 are provided on the vertical plate base 1. During installation, this structure can be installed on the machine tool from the base 11 with bolts. The reinforcing frame 12 is used to improve the stability of the connection between the vertical plate base 1 and the base 11.

[0027] In this embodiment, the cleaning-type tool integrated mechanism 2 includes a servo motor 21 and a tool disc 22. The servo motor 21 is fixedly installed on the left side of the vertical plate base 1, and the tool disc 22 is rotatably connected to the right side of the vertical plate base 1. The output shaft of the servo motor 21 is fixedly connected to the left side of the tool disc 22. A hollow disc 28 is fixedly installed at the center of the right side of the tool disc 22. A solenoid valve 281 is fixedly connected to the outer wall of the hollow disc 28. A connecting pipe 282 is fixedly connected to the end of the solenoid valve 281 away from the hollow disc 28. A hollow block 283 is fixedly connected to the end of the connecting pipe 282 away from the solenoid valve 281. A nozzle 284 is fixedly connected to the right side of the hollow block 283. A support sleeve 29 is fixedly installed on the right side of the hollow disc 28. An air tank 291 is fixedly installed on the inner wall of the support sleeve 29. A connecting pipe 293 is fixedly connected to the top of the air tank 291. The end of the connecting pipe 293 away from the air tank 291 is fixedly connected to the hollow disc 283. On the right side of the disc 28, an air pump 292 is fixedly installed on the top of the gas tank 291. The output pipe of the air pump 292 is fixedly connected to the top of the gas tank 291. The air pump 292 is an existing micro air pump that uses a DC motor to drive a diaphragm structure to deliver gas. It supports pressure feedback and automatic start / stop functions. When the air pump 292 is working, it can store gas at a specified pressure inside the gas tank 291. Before the combined cutter 25 is reset, it controls the corresponding solenoid valve 281 to open, which can deliver the pressurized gas inside the gas tank 291 through the connecting pipe 293, the hollow disc 28, the solenoid valve 281, and the connecting pipe 282 to the inside of the hollow block 283. The air then passes through the nozzle 284 and is sprayed to the right. The air flows through the inner cavity of the sheath 24 and the surface of the combined cutter 25. With the help of the air flow, the metal debris on the inner wall of the sheath 24 and the surface of the combined cutter 25 is cleaned away, ensuring the safety of the combined cutter 25.

[0028] In this embodiment, a bracket 23 is fixedly installed on the right side of the cutter head 22, and a blade sheath 24 is fixedly installed on the inner wall of the bracket 23. A combined cutting tool 25 is movably inserted into the inner cavity of the blade sheath 24, and a hydraulic cylinder 26 is fixedly installed on the outer wall of the blade sheath 24. The telescopic end of the hydraulic cylinder 26 extends into the inner cavity of the blade sheath 24 and is fixedly connected to a pressure block 27. During use, the combined cutting tool 25 in the blade sheath 24 is gripped and used by the device on the machine tool. After use, the combined cutting tool 25 can be reset back into the blade sheath 24. The control equipment controls the servo motor 21 to work, which can drive the cutter head 22 to rotate at a specified angle to move the corresponding combined cutter 25 to the pick-up and reset position. The pick-up and reset position is located at the top. Before the combined cutter 25 is picked up, the control hydraulic cylinder 26 retracts, which drives the pressure block 27 away from the outer wall of the combined cutter 25 to release the positioning of the combined cutter 25. After the combined cutter 25 is reset, the control hydraulic cylinder 26 extends, which drives the pressure block 27 to fit against the outer wall of the combined cutter 25 to complete the clamping and fixing of the combined cutter 25.

[0029] In this embodiment, the idle protection mechanism 3 includes a fixed ring seat 31 and a support seat 32. The fixed ring seat 31 is fixedly installed on the right side of the vertical plate seat 1, and the support seat 32 is fixedly installed on the outer wall of the vertical plate seat 1. A stepper motor 33 is fixedly installed on the top of the support seat 32, and a rotating shaft 34 is rotatably connected to the bottom of the support seat 32. The output shaft of the stepper motor 33 is fixedly connected to the top of the rotating shaft 34, and a connecting block 35 is fixedly installed on the bottom of the rotating shaft 34. A protective cover 36 is fixedly installed on the bottom of the connecting block 35. The protective cover 36 is movably connected to the right side of the fixed ring seat 31. In the initial state, the design of the protective cover 36 can wrap and protect the combined tool 25, realizing the functions of dust prevention and damage prevention during idle periods. Before use, the stepper motor 33 is controlled to work, which can drive the rotating shaft 34 to rotate at the bottom of the support seat 32. Through the transmission of the connecting block 35, the protective cover 36 is moved, causing the protective cover 36 to be withdrawn from the right side of the tool disc 22, making it convenient for the combined tool 25 to be used.

[0030] The working principle of this utility model's machine tool combination tool fixing structure is as follows: During installation, the structure can be installed on the machine tool from the base 11 using bolts. In use, the stepper motor 33 is first controlled to rotate the shaft 34 at the bottom of the support 32. Through the transmission of the connecting block 35, the protective cover 36 moves, causing it to retract from the right side of the tool disc 22. Then, the combination tool 25 inside the tool sheath 24 can be gripped and used using the machine tool's device. After use, the combination tool 25 can be returned to the inside of the tool sheath 24. The servo motor 21 is then controlled by the machine tool's control equipment to drive the tool... The disc 22 rotates at a specified angle to move the corresponding combined tool 25 to the pick-up and reset position. The air pump 292 is pre-controlled to work, accumulating gas at a specified pressure inside the air tank 291. Before the combined tool 25 is reset, the corresponding solenoid valve 281 is opened, allowing the pressurized gas inside the air tank 291 to be transported through the connecting pipe 293, hollow disc 28, solenoid valve 281, and connecting pipe 282 to the inside of the hollow block 283. The air then passes through the nozzle 284 and is sprayed to the right. The air flows through the inner cavity of the sheath 24 and the surface of the combined tool 25, realizing the automatic cleaning function before reset.
