[0021] The servo tool magazine body includes a fixed plate 8, a support seat 9, a slide rail 10, a slider 11, a cylinder 12, a servo motor 13, a turntable 14 and a tool support member 15. The fixed plate 8 is arranged at the middle position of the upper surface of the bridge-shaped fixed seat 3. The fixed plate 8 is connected to the middle position of the upper surface of the machine base 1 by bolts to realize the installation and disassembly of the fixed plate 8, thereby realizing the installation and disassembly of the entire servo tool magazine. The upper surface of the fixed plate 8 is provided with a support seat 9. The two sides of the upper surface of the support seat 9 are provided with slide rails 10. The two sides of the slider 11 are slidably connected to the slide rails 10. The height of the slider 11 is less than or equal to the horizontal height of the upper surface of the workbench 2 to ensure that the slider 11 will not hit the workbench 2 when it is pushed out. One end of the support seat 9 is provided with a cylinder 12. The piston rod of the cylinder 12 is connected to the slider 11 in a matching manner. The upper surface of the slider 11 is provided with a servo motor 13. The output shaft of the servo motor 13 is connected to a turntable 14.

The turntable 14 and the tool support member 15 are both movably arranged in the groove 7 of the bridge-shaped fixed seat 3.

[0022] Installation method and operating principle: First, install the fixed plate 8 equipped with the slide rail 10 at the middle position of the upper surface of the machine base 1 through bolts. Then, connect the servo motor 13 to the slider 11, and connect the turntable 14 to the output shaft of the servo motor 13. A number of tool support members 15 are installed around the turntable 14 through bolts. Subsequently, fit and connect the slider 11 with the slide rail 10, and install the motor and the lead screw pair to cooperate with the slider 11 at the same time. Finally, connect the X-axis slide 4 to the upper surface of the machine base 1 through a linear guide rail, and control the X-axis slide 4 to slide along the X-axis through the motor and the lead screw pair to cooperate with the X-axis slide 4. Connect the Y-axis slide seat 5 to the upper surface of the X-axis slide 4 through a linear guide rail, and control the Y-axis slide seat 5 to slide along the Y-axis through the motor and the lead screw pair to cooperate with the Y-axis slide seat 5. Connect the Z-axis EDM spindle 6 to one end of the Y-axis slide seat 5 close to the workbench 2 through a linear guide rail, and control the Z-axis EDM spindle 6 to lift along the Z-axis through the motor and the lead screw pair to cooperate with the Z-axis EDM spindle 6, thus completing the installation. During use, drive the slider 11 to move outward along the slide rail 10 through the motor and the lead screw pair until the corresponding empty tool support member 15 is located directly below the Z-axis EDM spindle 6. Subsequently, the Z-axis EDM spindle 6 moves toward one end close to the workbench 2 through the Y-axis slide seat 5. The Z-axis EDM spindle 6 moves downward through the corresponding motor and the lead screw pair, and makes the height of the tool match that of the tool support member 15. Then, move closer to the tool support member 15 through the Y-axis slide seat 5 until the top of the tool enters the U-shaped groove 16 of the tool support member 15. At this time, the Z-axis EDM spindle 6 releases the chuck, and the tool falls and is supported in the U-shaped groove 16 of the tool support member 15. The Z-axis EDM spindle 6 rises, the servo motor 13 drives the turntable 14 to rotate, and the tool support member 15 with a new tool rotates to directly below the Z-axis EDM spindle 6. The Z-axis EDM spindle 6 descends and is connected to the tool in cooperation. The chuck of the Z-axis EDM spindle 6 clamps the tool. The Z-axis EDM spindle 6 rises. At the same time, through the motor and the lead screw pair, the slider 11 moves toward the end away from the workbench 2 and hides in the bridge-shaped fixed seat 3, completing the tool change. The structure of the present utility model is reasonable. A bridge-shaped fixed seat 3 is provided on the upper surface of the machine base 1. The fixed plate 8 of the servo tool magazine body is installed on the upper surface of the machine base 1 and is located at the position of the bridge-shaped fixed seat 3. At the same time, the slider 11 and the turntable 14 are movably arranged in the groove 7 of the bridge-shaped fixed seat 3. When changing the tool, the tool support member 15 on one side of the turntable 14 is moved to the outside of the bridge-shaped fixed seat 3 through the motor and the lead screw pair to realize the tool change. When the tool change is completed, the turntable 14 can be completely retracted into the groove 7 of the bridge-shaped fixed seat 3, thereby realizing the hiding of the turntable 14. On the one hand, the installation of the servo tool magazine is realized, and on the other hand, the hiding of the servo tool magazine can be realized, so as to ensure that the machining is not affected by the servo tool magazine, avoid the collision between the spindle and the servo tool magazine, ensure the machining range and improve the safety during work.
