[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1-4This utility model provides a servo turret mechanism for a data machine tool, including an electrical component mounting plate 1 for integrating electrical control components, and a machine tool outer cover 2 covering the outside of the mechanism for protection. The machine tool outer cover 2 is characterized by: a turret control module mounting position 3 for mounting a turret control module inside the outer cover 2; a turret drive transmission component 4 for adapting and transmitting power to drive the turret movement; a turret 5 for driving tool switching; a spindle nose end 6 for connecting the workpiece machining spindle at the front end of the turret 5; a turret servo motor mounting base 7 for fixing the turret servo motor on one side of the turret 5; a spindle pulley 8 for connecting to an external power source on the turret servo motor mounting base 7; and square cutters distributed circumferentially around the turret 5. The turret 5 includes a tool holder 9 and a circular tool holder 10. A tool holder positioning sensor 11 monitors the tool holder's position and status. A turret lubrication assembly 12 supplies fluid lubrication to the rotating parts of the turret, and a turret rotation shaft 13 serves as the core support for the turret's rotation. The turret 5 is covered by a turret protective cover 14 that shields and protects the internal structure. A turret locking assembly 15 ensures the turret's operational stability at the connection point between the turret 5 and the machine tool. A turret servo motor heat dissipation channel 16 guides heat dissipation at the corresponding position of the turret servo motor. An internal protective cover 17 is fitted inside the machine tool outer cover 2. An auxiliary positioning component 18 assists in positioning and machining the area associated with the turret 5 and the workpiece. The machine tool outer cover 2 and the internal protective cover 17 form a double-layer protection, blocking external interference. The turret control module mounting position 3 houses the control module. After issuing a command, the turret drive transmission component 4 receives the power and transmits it to the turret 5. The servo motor mounting bracket 7 secures the servo motor, while the spindle pulley 8 connects to an external power source, providing power for the turret 5's operation. The turret rotation shaft 13 serves as the core of rotation, working in conjunction with the turret drive transmission component 4 to drive the turret 5 to rotate, enabling the switching between square tool holder 9 and round tool holder 10 positions. The tool holder positioning detection sensor 11 monitors the tool holder position in real time, and the turret lubrication component 12 supplies fluid to the rotating parts to reduce friction. The turret protective cover 14 shields the internal structure, the turret locking component 15 ensures stable turret operation, and the turret servo motor heat dissipation channel 16 dissipates motor heat. The turret auxiliary positioning component 18 works in conjunction with the spindle nose 6 to assist in precise tool machining.

[0022] One end of the turret drive transmission component 4 is connected to the control module on the turret control module mounting position 3, and the other end is driven by the turret 5. The power transmission path of the turret drive transmission component 4 covers the turret rotation shaft 13. The turret drive transmission component 4 drives multiple square tool holders 9 and multiple round tool holders 10 around the turret 5 to switch positions via the turret rotation shaft 13. The turret drive transmission component 4 obtains power and commands by connecting one end to the control module on the turret control module mounting position 3, and the other end is driven by the turret 5. The power is transmitted through the turret rotation shaft 13. Utilizing the rotation characteristics of the turret rotation shaft 13, the turret drive transmission component 4 drives the square tool holders 9 and round tool holders 10 around the turret 5 to switch to the target position according to the control commands. This achieves fast and accurate switching of tool holder positions, ensures tool changing accuracy and machining continuity, and solves the problem of easy deviation in traditional tool changing.

[0023] The turret servo motor mounting base 7 is fixed in the corresponding position inside the outer cover 2 of the machine tool. The power output end of the turret servo motor mounting base 7 has a spindle pulley 8 installed, and the spindle pulley 8 is connected to the external power mechanism through a transmission belt. The turret servo motor mounting base 7 serves as a fixed carrier to stably install the servo motor inside the outer cover 2 of the machine tool. The spindle pulley 8 at its power output end is connected to the external power mechanism, such as the motor or spindle box, through a transmission belt. The external power is transmitted to the turret servo motor mounting base 7 through belt transmission, thereby providing continuous and stable basic power for the turret 5 and related components such as the turret drive transmission component 4 and the turret rotation axis 13.

[0024] The tool holder positioning detection sensor 11 is installed on the turret 5 near the square tool holder 9 and the round tool holder 10. The outlet of the turret lubrication assembly 12 faces the turret rotation shaft 13 and the transmission contact part of the turret 5. Based on the sensing principle, the tool holder positioning detection sensor 11 is arranged on the turret 5 near the square tool holder 9 and the round tool holder 10 to collect signals such as tool holder position and installation status in real time and feed them back to the control system. According to the lubrication requirements, the turret lubrication assembly 12 accurately delivers the lubricant through the outlet to the turret rotation shaft 13 and the transmission contact part of the turret 5 to form an oil film to reduce friction.

[0025] The turret protective cover 14 covers the outside of the turret 5 and is spatially adapted to the inner protective cover 17 of the machine tool. The turret locking assembly 15 is installed at the connection structure between the turret 5 and the inner protective cover 17 or the outer large cover 2 of the machine tool. The turret protective cover 14 covers the outside of the turret 5 by physical shielding and is spatially adapted to the inner protective cover 17 of the machine tool to form a closed protective space to prevent cutting fluid, iron filings and other contaminants from entering. The turret locking assembly 15 is installed at the connection structure between the turret 5 and the inner protective cover 17 or the outer large cover 2 of the machine tool. When the turret 5 is working, it fixes the position of the turret 5 by mechanical locking such as clamping or locking to suppress working vibration.

[0026] The turret servo motor heat dissipation channel 16 connects the turret servo motor mounting base 7 with the outer space of the machine tool outer cover 2, and the turret servo motor heat dissipation channel 16 extends to the heat-generating area of ​​the turret servo motor. The turret servo motor heat dissipation channel 16 utilizes the principle of air convection or heat conduction, with one end connected to the heat-generating area of ​​the motor in the turret servo motor mounting base 7 and the other end extending to the outer space of the machine tool outer cover 2. The channel extends to the heat-generating area, guiding heat from the high-temperature area of ​​the motor to the low-temperature area of ​​the outer space, thereby achieving heat dissipation.

[0027] The turret auxiliary positioning component 18 is positioned on the side of the turret 5 facing the workpiece and works in conjunction with the spindle nose 6 at the machining station. The installation position of the turret auxiliary positioning component 18 is adapted to the station switching range of multiple square tool holders 9 and multiple round tool holders 10. By installing the turret auxiliary positioning component 18 on the side of the turret 5 facing the workpiece and working in conjunction with the spindle nose 6 at the machining station, when the turret 5 drives the tool to switch to the machining position, the turret auxiliary positioning component 18 assists in the precise alignment of the tool with the workpiece and the spindle nose 6 through mechanical contact, positioning pin / hole engagement, etc. Its installation position is adapted to the station switching range of the square tool holders 9 and round tool holders 10, ensuring that auxiliary positioning support can be obtained after switching between different tool holders.

[0028] In this invention, a precision transmission system is constructed by designing the turret drive transmission component 4 as a high-precision gear or synchronous belt drive structure, and cooperating with the high-precision rotation design of the turret rotation shaft 13. During indexing and tool changing of the turret 5, the high-precision turret drive transmission component 4 accurately transmits the power of the servo motor to the turret 5 through the commands from the turret control module mounting position 3, reducing power loss and errors during transmission. Meanwhile, the turret rotation shaft 13, with its high-precision rotation characteristics, ensures that the turret 5 maintains stable and precise angle control during rotation. The combined work of these two components allows the turret 5 to be precisely positioned during each tool change, significantly improving the transmission accuracy of indexing and tool changing, and effectively reducing tool position deviation. This principle ensures that the workpiece maintains the same machining dimensions after each tool change during multi-process machining, thereby ensuring the consistency of workpiece machining dimensions, meeting high-precision machining requirements, and improving product quality and machining reliability.

[0029] By configuring a double-layer protective structure of the turret protective cover 14 and the machine tool inner protective cover 17, a physical barrier is formed for the internal transmission and electrical components of the turret 5. The machine tool inner protective cover 17 serves as the inner layer of protection, blocking nearby cutting fluid splashes and fine iron filings; the turret protective cover 14 serves as the outer layer of protection, further strengthening the protection of critical parts of the turret 5. The two layers of protection work closely together to effectively prevent external impurities from entering the interior of the turret 5, preventing them from damaging or interfering with the transmission components and electrical components. At the same time, the turret servo motor heat dissipation channel 16 adopts a directional heat dissipation design. One end of this channel is tightly connected to the heat-generating area of ​​the servo motor mounted on the turret servo motor mounting base 7, and the other end extends to the outside of the machine tool outer cover 2. Through the principles of air convection and heat conduction, the heat generated by the servo motor during operation is dissipated in a timely manner, preventing the motor from degrading in performance or aging prematurely due to overheating. The combination of all-dimensional protection and heat dissipation design, starting from preventing external damage and controlling internal operating temperature, effectively slows down the aging rate of the components of the turret 5, reduces the frequency of equipment maintenance, thereby significantly improving the overall service life of the turret 5, reducing downtime maintenance time, and improving the production efficiency and economic benefits of the machine tool.

[0030] A real-time monitoring and feedback system is constructed by arranging high-sensitivity tool holder positioning and detection sensors 11 next to the square tool holder 9 and the round tool holder 10. These sensors can quickly and accurately detect whether the installation position of the tool holder is accurate and whether the locking state is reliable, and feed the collected information back to the machine tool control system in real time. During tool changing, once the tool holder reaches the target position and locks, the sensor 11 can quickly transmit the tool changing completion signal to the control system, which then promptly starts the subsequent machining process, avoiding time wastage caused by waiting for the tool changing confirmation signal. This real-time monitoring and feedback mechanism ensures the timely transmission of the tool changing completion signal, enabling the machine tool's machining process to be closely connected and ensuring the continuity of the machining cycle. At the same time, because it can promptly detect and alarm abnormalities in tool holder installation or locking, it avoids machining failures and scrap caused by tool holder problems, thereby helping CNC machine tools achieve efficient and precise machining, improving production efficiency and machining quality stability.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
