Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the scope of protection of the present utility model.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: a quick-change tool magazine for a metal processing center with a temporary fixing function, including a tool magazine center and a temporary fixing mechanism. The tool magazine center includes a housing 1, a turntable 7, an electric push rod 2, a plurality of tool holders 3, and a plurality of tool seats 4;

[0019] The temporary fixing mechanism includes a motor 5, a driving cavity 6, and a temporary fixing part;

[0020] The electric push rod 2 is fixedly installed in the middle of the inner wall of the housing 1. A plurality of tool holders 3 are distributed and fixedly installed around the inner wall of the turntable 7. A plurality of tool seats 4 are respectively pivotally connected to a plurality of tool holders 3. Tools are provided inside each of the plurality of tool holders 3;

[0021] A driving motor 8 is fixedly installed on the left side of the housing 1. The turntable 7 is fixedly connected to the output end of the driving motor 8, and the turntable 7 is located inside the housing 1;

[0022] When changing tools, the driving motor 8 operates, drives the turntable 7 to rotate through its output end. The turntable 7 drives a plurality of tool seats 4 and tool holders 3 to rotate around its center. When the tool seat 4 rotates below the electric push rod 2, the electric push rod 2 operates, pushing the horizontal tool seat 4 to rotate on the tool holder 3 through the shaft until the tool seat 4 is vertical, making the tool vertical, so as to perform the tool change work. At the same time, the temporary fixing mechanism operates to temporarily fix the tool, which can effectively avoid the phenomenon of the tool falling and play a role in protecting the tool.

[0023] A driving mechanism is provided inside the driving cavity 6. The driving mechanism is fixedly connected to the output end of the motor 5. The temporary fixing part includes a tool turning frame 9;

[0024] The tool turning frame 9 is fixedly connected to the output end of the driving mechanism.

[0025] Clamping rings 10 are provided on both the left and right sides of the tool turning frame 9;

[0026] Through the above steps, when the tool is in a vertical state, the motor 5 operates. Through its output end, the driving mechanism is driven to operate. The driving mechanism drives the rotating tool holder 9 to rotate through its output end until the rotating tool holder 9 holds the tool by means of the clamping ring 10, playing a role in temporarily fixing the tool. Then the motor 5 rotates forward and backward, driving the tool to rotate around the center of the rotating tool holder 9 to the other side, so as to facilitate the tool changing operation. The operation is automated, convenient and efficient, and plays an efficient role in protecting the tool.

[0027] A ejector rod 11 is arranged inside the clamping ring 10. The ejector rod 11 is slidably connected inside the rotating tool holder 9, and a spring is arranged inside.

[0028] After the rotating tool holder 9 holds the tool, the ejector rod 11 slides inside the rotating tool holder 9 under force, and at the same time the spring is deformed under force. The reaction force generated by the spring pushes the ejector rod 11 to hold the tool, thereby further improving the fixing force of the tool and preventing the tool from falling due to looseness between the tool and the rotating tool holder 9 during the rotation of the rotating tool holder 9, and further improving the protection performance of the tool.
