[0002] The servo tool magazine is an important component for automatic tool replacement in CNC machine tools. It controls the rotation of the tool disc of the tool magazine through a servo motor, so that the tool can be automatically replaced during the machining process. There are multiple tool positions on the tool magazine body, which can store multiple tools, making tool replacement more convenient.

[0003] The tool clamps used in some existing servo tool magazines are relatively tight, with basically no room for movement. Sometimes they can easily get stuck if they are slightly tilted. Long-term use can easily cause damage to the tool clamps. During the machining process of the machine tool, it is easy for debris to fly around, causing the debris to enter the tool magazine and cause internal parts to get stuck and damaged.

[0025] 1. The utility model proposes a high-efficiency, high-precision, fast-tool-changing servo tool magazine. The servo tool magazine is provided with a movable mechanism. When changing the tool, when the tool is passed through the inclined surface of the inner wall of the tool clamp, the tool clamp moves slightly to both sides, so that the second hinged rod drives the moving block to move slightly forward, thereby driving the connecting rod to move slightly forward, thereby compressing the spring. When the tool is clamped to the groove of the inner wall of the tool clamp, the connecting rod moves to its original position through spring rebound, thereby driving the moving block to move to its original position, and then the second hinged rod is driven by the moving block so that the tool clamp can clamp the tool, thereby achieving a certain amount of activity space for the tool clamp and extending the service life of the tool clamp.

[0026] 2. The utility model proposes a high-efficiency, high-precision, fast-tool-changing servo tool magazine. The servo tool magazine is extended by a telescopic rod, so that one end of the first hinged rod is subjected to an outward force by the telescopic rod, so that the other end of the first hinged rod also moves to one side, thereby driving the switch housing to open, the telescopic rod to shorten inward, and the switch housing to close through the first hinged rod, thereby realizing automatic opening and closing of the switch housing.
