[0003] The prior art CN212444269U discloses a device for quickly changing tools for CNC machine tools. A new tool is placed in a receiving block through a feeding mechanism, and then the receiving block is driven to rotate by a motor, and the tool is installed in conjunction with a clamping mechanism to facilitate replacement of a new tool. When replacing the tool, the motor drives the tool to rotate, causing the old tool to fall into a recycling box, which is convenient for recycling. The operation is simple, time-saving, and practical.

[0026] Again, the rotation of the rotating tool holder 102 on the support seat 101 is achieved by a rotating motor 115, the output shaft of the rotating motor 115 is connected to the rotating tool holder 102, the rotating motor 115 is arranged on the support seat 101, the output shaft of the rotating motor 115 is connected to the rotating tool holder 102, and drives the rotating tool holder 102 to rotate on the support seat 101 along the axis of the output shaft of the rotating motor 115.

[0027] At the same time, the rotating tool holder 102 has a groove 116, the first hydraulic telescopic rod 106 is arranged in the groove 116, the output end of the first hydraulic telescopic rod 106 is connected to the second hydraulic telescopic rod 107, the output end of the second hydraulic telescopic rod 107 is connected to the first knife claw, the second hydraulic telescopic rod 107 is located on the side of the first hydraulic telescopic rod 106 close to the first knife claw, the output end of the first hydraulic telescopic rod 106 is connected to the second hydraulic telescopic rod 107, and drives the second hydraulic telescopic rod 107 to move longitudinally in the groove 116 of the rotating tool holder 102, and the output end of the second hydraulic telescopic rod 107 is connected to the first knife claw, and drives the first knife claw to move laterally outside the rotating tool holder 102.

[0028] In addition, the limiting plate 109 is disposed on a side of the clamping ring 108 close to the rotating tool holder 102 . By providing the limiting plate 109 , the clamping position of the tool 103 can be limited.

[0030] Finally, the movement of the second knife claw 105 on the rotating disk 104 is achieved by a pneumatic telescopic rod 119, and the output end of the pneumatic telescopic rod 119 is connected to the second knife claw 105. The pneumatic telescopic rod 119 is arranged on the side of the rotating disk 104 away from the rotating block 113.

Through the movement of multiple second knife claws 105, the tool 103 is clamped and fixed.

[0031] When using the quick tool changing device for a cemented carbide tool of the present embodiment, the tool 103 is placed between the two oppositely arranged clamping rings 108, and the tool 103 is pushed to move in the direction close to the limit plate 109. When the tool 103 contacts the limit plate 109, the second hydraulic telescopic rod 107 is started, so that the power output from the output end of the second hydraulic telescopic rod 107 drives the clamping ring 108 of the first tool claw to move laterally outside the rotating tool holder 102, so that the tool 103 can be clamped and fixed between the two oppositely arranged clamping rings 108. Then, the first hydraulic telescopic rod 106 is started, so that the power output from the output end of the first hydraulic telescopic rod 106 drives the second hydraulic telescopic rod 107 to move longitudinally in the groove 116 of the rotating tool holder 102, thereby driving the clamping ring 108 to move longitudinally outside the rotating tool holder 102, and further driving the tool 103 to move longitudinally outside the rotating tool holder 102, so as to facilitate processing of metal products.
