Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the drawings here can be arranged and designed in various different configurations.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0023] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0024] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings or the orientation or positional relationship in which the product of the application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0025] In addition, the terms "horizontal", "vertical", "overhanging", etc. do not mean that the components are required to be absolutely horizontal or overhanging, but may be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly inclined.

[0026] In the description of the present application, it should also be noted that unless otherwise clearly defined and limited, the terms "arranged", "installed", "connected", "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0027] See Figures 1-3As shown in the figure, the automatic material extraction device of the CNC milling machine described in this embodiment includes a milling machine A-axis rotary table 1, a milling machine spindle 2, a mounting template 3, a plurality of material fixing structures 4, and a material extraction structure 5. The mounting template 3 is installed on the milling machine A-axis rotary table 1. A plurality of the material fixing structures 4 are arranged at intervals on the mounting template 3 and are used to press the material to be processed. A tool holder 21 is provided below the milling machine spindle 2. The material extraction structure 5 is installed on the tool holder 21 and is used to clamp and extract the material located on the material fixing structure 4 to achieve automatic material extraction.

[0028] The structure of this embodiment is simple and reasonable in design. By setting a plurality of material fixing structures 4, it can cooperate with the material extraction structure 5 to complete the processing of the materials on a plurality of material fixing structures 4 in sequence, and then manually replace the next batch of materials, thereby shortening the material change frequency and effectively improving the processing efficiency and stability.

[0029] Specifically, during processing, the material is made into a short rod and installed on the mounting template, and the material is pressed. The mounting template is installed on the milling machine A-axis rotary table 1. A material extraction structure 5 is set on the milling machine spindle 2. The first material change is manually performed by the operator outside the equipment. After the machine tool processes the first product, the material extraction structure 5 descends to clamp the first material and clamps the material. Then, the material fixing structure 4 of the first material is loosened by a certain gap, such as 0.1 - 0.5 mm, so that the material is only clamped by the material extraction structure 5 but still remains in the groove of the mounting template 3. Then, through the machine tool program, the material extraction structure 5 raises the material by the length of one product, and the material fixing structure 4 clamps the material again. Then, the material extraction structure 5 is raised through the program. At this time, the material has been pressed, and the pressing force is greater than that of the material extraction structure 5. Therefore, when the material extraction structure 5 is raised again, it will automatically disengage from the material, thus completing the material extraction operation of the first material. By analogy, the material extraction operations of other materials are completed. When a batch of materials is processed, the machine tool gives a prompt, and then the operator replaces the next batch of materials manually. Such a design improves the production efficiency and reduces the material change frequency.

[0030] In some embodiments, the mounting template 3 is fixedly connected to the milling machine A-axis rotary table 1 by screwing.

[0031] In this embodiment, it is specifically shown that the mounting template 3 is fixedly installed by screwing. Its structure is simple, easy to disassemble and assemble, and convenient for disassembly and assembly during the material replacement process.

[0032] In some embodiments, a positioning groove 31 for defining the material to be processed is provided on the mounting template 3.

[0033] In this embodiment, by setting the positioning groove 31, it is convenient to cooperate with the material fixing structure 4 for material installation positioning and limiting during the fixing process.

[0034] In some embodiments, the material fixing structure 4 is provided with a cylinder 41 for pressing the material.

[0035] Specifically, the material fixing structure 4 is further provided with a pressing block 42, which contacts the material to be pressed and is connected to the cylinder 41 through a connecting rod 43.

[0036] In this embodiment, it is specifically shown that the material is pressed by the cooperation of the pressing block 42 and the cylinder 41. Specifically, the cylinder 41 and the pressing block 42 can be arranged on opposite sides of the mounting template 3, and the cylinder 41 and the pressing block 42 can be drivingly connected by passing the connecting rod 43 through the mounting template 3.

[0037] In some embodiments, the material pulling structure 5 is provided with a clamping knife 51 for clamping the material.

[0038] Specifically, the material pulling structure 5 is further provided with a spring member 52, which is connected to the clamping knife 51 and is used to drive the clamping knife 51 to close to clamp the material.

[0039] In this embodiment, by setting the clamping knife 51 and the spring member 52 to cooperate, it is convenient to realize the clamping of the material by the material pulling structure 5. Its structure is simple and the material clamping is convenient.

[0040] See Figures 1-2 As shown, the material fixing structure 4 has at least three.

[0041] In this embodiment, it is specifically shown that three material fixing structures 4 are provided. Based on the batch requirements of the production products, the number of the material fixing structures 4 can be flexibly increased to meet the production and processing needs. This is only an example here and does not limit the number of the material fixing structures 4.

[0042] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
