Example 2

[0025] Based on the above embodiment one, please refer to Figures 1 to 5 A rotary swashplate tool magazine has a drive structure 1 comprising an internal gear ring 16, a transmission gear 11, a power gear 17, a fixed base plate 15, and an assembly frame 13. The internal gear ring 16 is fixedly mounted on the outer side of the middle of the swashplate tool magazine 3. The fixed base plate 15 is mounted on the inner side of the middle of the swashplate tool magazine 3. The assembly frame 13 is mounted on the outer side of the middle of the swashplate tool magazine 3. The transmission gear 11 is rotatably mounted on one side of the fixed base plate 15 and the assembly frame 13. The power gear 17 is mounted at the middle position of the fixed base plate 15 and the assembly frame 13. The transmission gear 11 meshes with the internal gear ring 16 and the power gear 17 respectively.

[0026] Furthermore, a servo drive motor 14 is fixedly installed at the middle of the rear end of the assembly frame 13, and the power gear 17 is driven by the servo drive motor 14; the arrangement of the servo drive motor 14 and the power gear 17 facilitates the rotation of the power gear 17 by the servo drive motor 14.

[0027] Furthermore, multiple guide wheels 12 are equidistantly rotatably arranged between the assembly frame 13 and the fixed base plate 15, near the side, and the multiple guide wheels 12 are mutually limited and engaged with the swashplate tool magazine 3 in a rolling cooperation; the arrangement of the multiple guide wheels 12 and the cooperation between the multiple guide wheels 12 and the swashplate tool magazine 3, through the structure of the guide wheels 12, ensures the smoothness of the rotation adjustment of the swashplate tool magazine 3, and at the same time plays the role of supporting the swashplate tool magazine 3 as a whole while ensuring that the swashplate tool magazine 3 itself can be rotated and adjusted.

[0028] The working principle and usage process of this utility model: In actual use, the operator installs the equipment onto the required CNC machine tool through the assembly frame 13. After the installation of the equipment is completed;

[0029] At this time, the operator can reset the equipment by controlling the CNC lathe with one key. At this time, the servo drive motor 14 drives the power gear 17, transmission gear 11 and internal gear ring 16 to drive the swashplate tool magazine 3 connected to the internal gear ring 16 to rotate and adjust. When the rotation is adjusted to correspond to the infrared reset receiving sensor 22 and the infrared reset transmitting sensor 25, the transmitted signal is fed back to the lathe control terminal, so that the control terminal quickly issues a command to control the servo drive motor 14 to stop working. At this time, the tool clamping structure 4 corresponding to the zero point is located directly below the swashplate tool magazine 3 and corresponds to the tool drive structure of the CNC lathe, thus completing the reset of the swashplate tool magazine 3.

[0030] Next, the operator calibrates the equipment through the control terminal on the CNC lathe. At this time, driven by the servo drive motor 14, the swashplate tool magazine 3 will stop rotating when it aligns with an infrared receiving sensor 21 and an infrared emitting sensor 24. The operator can then observe whether the tool clamping structure 4 at the corresponding position is located directly below the tool magazine. By repeating this operation, the equipment calibration can be completed.

[0031] When the equipment is working, the control terminal can control the servo drive motor 14 to drive the swashplate tool magazine 3 to rotate according to the machining program entered by the CNC lathe. The magnetic tool holder 5 of the corresponding tool is adjusted to be located below the tool drive structure of the CNC lathe. The magnetic tool holder 5 is quickly installed by magnetic attraction, realizing the quick tool change operation.

[0032] The overall design allows the device to achieve rapid tool switching and positioning operations by using infrared positioning, unlike traditional tool magazines that rely solely on the precision of the servo drive system. This reduces the precision requirements of the servo drive system and also features a one-button quick reset design, facilitating precision calibration of the device.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
