For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0023] As shown in Figures 1 to 2 A disc tool magazine for numerical control machining, wherein the embodiment comprises a primary rotating disc 1 and a plurality of secondary rotating discs 2, a first transmission assembly 3 for driving the primary rotating disc 1 to rotate is arranged below the primary rotating disc 1, the plurality of secondary rotating discs 2 are uniformly arranged around the axis of the primary rotating disc 1, a plurality of clamping stations for storing various types of tools are arranged on the top surface of each secondary rotating disc 2 in the circumferential direction, and a second transmission assembly 4 for driving each secondary rotating disc 2 to independently rotate is arranged below each secondary rotating disc 2.

[0024] The first rotating disc 1 is used as the main base disc, and a plurality of second rotating discs 2 are arranged around the first rotating disc 1, and a plurality of clamping stations are arranged in each second rotating disc 2, so that the tool storage capacity of the tool magazine can be greatly increased. The clamping station is composed of two clamping blocks, and can be controlled by the tool magazine control system to approach or move away from each other to clamp or release the tool, and cooperate with the tool changing robot to perform tool changing operation. A first transmission assembly 3 is arranged below the first rotating disc 1, and a second transmission assembly 4 capable of independently controlling the rotation of the second rotating disc 2 is arranged below each second rotating disc 2. When tool changing is required, the numerical control system sends a command to the tool magazine system according to the requirements of the machining program, indicating which tool to change, and after receiving the command, the tool magazine control system drives the first transmission assembly 3 to rotate the first rotating disc 1 to the predetermined position, ensuring that the second rotating disc 2 with the required tool is aligned with the tool changing position of the tool changing robot. The corresponding second rotating disc 2 rotates through the second transmission assembly 4 to position the required tool at the tool changing position, and a position sensor 5 for detecting the position of the tool is arranged at the edge of the first rotating disc 1. The sensor 5 can detect whether the tool is correctly placed in the clamping station and feed back to the numerical control system. When the required tool is positioned in the appropriate position, the tool changing robot starts to work, first removes the old tool, and then installs the new tool on the main shaft of the machine tool.

[0025] As shown in Figure 1 and Figure 2 , the first transmission assembly 3 of the embodiment includes a shaft seat 31 arranged at the center of the first rotating disc 1, a first drive motor 32 connected with the shaft seat 31, and a reduction box 33 arranged at the output end of the first drive motor 32. The shaft seat 31 is located at the center of the first rotating disc 1 and serves as the core support structure of the first transmission assembly 3, bearing the rotating shaft of the first rotating disc 1. The first drive motor 32 is electrically connected with the numerical control system for providing rotating power, and is a servo motor that can provide high positioning accuracy and good dynamic response characteristics. By receiving the command of the numerical control system, the first drive motor 32 drives the first rotating disc 1 to rotate to the specified position. A reduction box 33 is arranged at the output end of the first drive motor 32 to convert the high-speed rotation of the motor into low-speed high-torque motion suitable for the rotation of the first rotating disc 1, ensuring that the first rotating disc 1 can be positioned smoothly and accurately.

[0026] As shown in Figure 1 and Figure 2 , the second transmission assembly 4 of the embodiment includes a driven shaft 41 arranged at the center of the second rotating disc 2 and a second drive motor 42 connected with the driven shaft 41. The driven shaft 41 is located at the center of each second rotating disc 2 and is directly connected with the second drive motor 42. When the first rotating disc is rotated to the appropriate position, the second drive motor 42 is started after receiving the command, and the rotating power is transmitted to the second rotating disc 2 through the driven shaft 41, so that the specified tool is rotated to the specified position and positioned for tool changing.

[0027] Furthermore, each clamping station in this embodiment is equipped with a sensor 5 for detecting the position of the cutting tool. Each sensor 5 is installed inside each clamping station and can be a photoelectric sensor 5 or a proximity sensor 5, capable of detecting whether the cutting tool is stored in the clamping station.

[0028] like Figure 2 As shown, in this embodiment, the bottom of the primary turntable 1 is provided with a rotating groove 6 corresponding to the position of each secondary turntable 2 to provide space for tool rotation. The rotating groove 6 is located at the bottom of the primary turntable 1, corresponding to the position of each secondary turntable 2. Its shape and size are designed according to the size of the secondary turntable 2 and the tool, providing sufficient space for the rotation of the tool in the secondary turntable 2, and ensuring that the tool is not obstructed by the primary turntable 1 when rotating.

[0029] In summary, the beneficial effects of this embodiment are as follows: By setting a primary turntable 1 as the main base and evenly distributing multiple secondary turntables 2 around it, with each secondary turntable 2 having multiple clamping stations, the tool storage capacity of the tool magazine is greatly increased. The primary turntable 1 is driven by a first transmission assembly 3, which includes a spindle seat 31, a servo motor, and a reduction gearbox 33, enabling high-precision positioning. The secondary turntables 2 rotate independently through their respective second transmission assemblies 4, allowing the secondary turntables 2 to rotate again after the primary turntable 1 has rotated, ensuring that the designated tool can be accurately positioned at the tool change position.

[0030] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
