[0002] The power turret is a key core component used in CNC machine tools. Traditional turrets can only be equipped with turning tools or boring tools for basic turning operations. The power turret uses a single built-in servo motor to control the precise indexing of the turret (also known as tool changing) and control the high-speed rotation of the rotary tool, integrating turning and milling operations. The power turret is usually mounted on the machine tool guide rail and works with the workpiece held by the machine tool spindle. It controls the machine tool movement according to digital information to process the workpiece. The power turret can also independently drive the movement of the tool holder to process the workpiece.

[0003] Existing hydraulic servo turrets are rigidly connected to CNC lathes using only bolts during installation, resulting in cumbersome disassembly and assembly of the turret body, making them unsuitable for industrial applications.

[0004] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0023] Please see Figures 1 to 3 A CNC lathe turret device includes a turret body 10 and a mounting base 20 connected to the turret body 10. The mounting base 20 includes a first connecting plate 201, a clamping plate 202, and a first drive assembly. The first connecting plate 201 is used to connect to an external CNC lathe. Two clamping plates 202 are provided, and the two clamping plates 202 are installed above the first connecting plate 201. A T-shaped locking block 203 is provided on the opposite side of the two clamping plates 202. The first drive assembly is installed on the first connecting plate 201 and is used to drive the two clamping plates 202 to move closer or further apart. In the working state, the turret body 10 is installed between the two clamping plates 202, and the side of the turret body 10 is provided with a T-shaped slot 204 corresponding to the T-shaped locking block 203. When the first drive assembly drives the two clamping plates 202 to move closer together, the T-shaped locking block 203 engages in the T-shaped slot 204.

[0024] In this embodiment, the first connecting plate 201, clamping plate 202, T-shaped locking block 203 and the first driving component of the mounting base 20 can effectively and stably connect the turret body 10 to the CNC lathe. When disassembly is required, the two clamping plates 202 can be driven away from each other by the first driving component, which makes the installation and disassembly of the turret body 10 simple and quick, and suitable for industrial applications.

[0025] In one specific embodiment, the first driving assembly includes a double-ended lead screw installed within a first connecting plate 201, and a drive motor 205 connected to the double-ended lead screw for driving its rotation. Two clamping plates 202 are respectively installed on two reverse threaded sections of the double-ended lead screw, allowing them to move closer or further apart when the double-ended lead screw rotates. Specifically, in this embodiment, the upper end of the first connecting plate 201 is provided with a mounting groove for installing the double-ended lead screw. The double-ended lead screw is installed in the mounting groove, and the clamping plates 202 are respectively located on the two reverse threaded sections of the double-ended lead screw and connected to the double-ended lead screw via a first connecting block. During operation, the drive motor 205 drives the double-ended lead screw to rotate, thereby causing the two clamping plates 202 to move closer or further apart. Further, three mounting grooves are arranged side-by-side on the first connecting plate 201. The double-ended lead screw is located in the middle mounting groove, and guide rods are installed in the other two mounting grooves. A second connecting block connected to the clamping plate 202 is sleeved on the outer side of the guide rod to ensure the stability of the clamping plate 202 during movement.

[0026] In one specific embodiment, a second connecting plate 206 is mounted on the upper part of the clamping plate 202; a cooling module 207 for dissipating heat from the turret body 10 is provided above the second connecting plate 206; a second driving component is provided on one side of the cooling module 207 for driving the cooling module 207 to approach and fit against the side of the turret body 10. Specifically, in this embodiment, during operation, after the first driving component drives the clamping plate 202 to clamp the turret body 10, the second driving component drives the cooling module 207 to fit against the turret body 10 to effectively dissipate heat from the turret body 10, greatly improving the service life of the turret body 10 and enhancing the user experience.

[0027] In one specific embodiment, the second connecting plate 206 is provided with a mounting frame 208, and the cooling module 207 is detachably mounted in the mounting frame 208; the second driving assembly is connected to the mounting frame 208 and is used to drive the mounting frame 208 to move toward the turret body 10. Specifically, in this embodiment, the mounting frame 208 is provided to facilitate the separate assembly and disassembly of the cooling module 207, thereby facilitating the maintenance and replacement of the cooling module 207.

[0028] In one specific embodiment, the cooling module 207 has inserts 209 on both sides; the mounting frame 208 has slots 210 for inserting the inserts 209. Specifically, in this embodiment, the cooling module 207 can be quickly installed in the mounting frame 208 by means of the slots 210 and the inserts 209; furthermore, the mounting frame 208 has a first threaded mounting hole 210 that passes through the slots 210; the inserts 209 have second threaded mounting holes corresponding to the first threaded mounting holes 210. When the inserts 209 are in the slots 210, the cooling module 207 is securely installed in the mounting frame 208 by bolts engaging the first threaded mounting holes 210 and the second threaded mounting holes.

[0029] In one specific embodiment, the second drive assembly includes a drive cylinder 211 mounted on one side of the mounting frame 208 and connected to the mounting frame 208, for driving the mounting frame 208 to move toward the side of the turret body 10.

[0031] In one specific embodiment, a base plate 212 is provided at the bottom of the first connecting plate 201, and an elastic buffer assembly is provided between the base plate 212 and the first connecting plate 201. The base plate 212 is provided with a connection hole for connecting to an external CNC machine tool; existing hydraulic servo turrets are rigidly connected to external lathes using only bolts. Because the tool generates strong vibrations during cutting, the nuts are prone to loosening under strong vibrations, resulting in increased amplitude of hydraulic servo turret swaying, which affects machining quality; in this embodiment, the base plate 212 is connected to the CNC lathe, and the elastic buffer module effectively reduces the vibration force generated by the CNC machine tool during use, thereby improving the service life of the device.

[0032] In one specific embodiment, the elastic buffer module includes a buffer spring 213 and a damper 214 connected to the first connecting plate 201 and the base plate 212.

[0033] In one specific embodiment, the first connecting plate 201 is provided with a guide hole; the turret body 10 is provided with a guide block corresponding to the guide hole; in the installation state, the guide block is installed in the guide hole. In this embodiment, the guide hole and the guide block are provided to quickly complete the initial positioning between the turret body 10 and the first connecting plate 201, so that the T-shaped locking block 203 can be engaged in the T-shaped locking slot 204.

[0034] The CNC lathe turret device disclosed in this utility model, through the arrangement of the first connecting plate 201, clamping plate 202, T-shaped block 203 and first drive component of the mounting base 20, can effectively and stably connect the turret body 10 to the CNC lathe. When disassembly is required, the two clamping plates 202 can be driven away from each other by the first drive component, thereby making the installation and disassembly of the turret body 10 simple and quick, and suitable for industrial applications.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
