[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a tool changing structure of a tool magazine. Figure 1 and Figure 2 A tool changing structure of a tool magazine includes a base 1, a spindle 2 and a cutter disc 3. The base 1 abuts the ground to form a support, and the cutter disc 3 is rotatably connected to the top surface of the base 1. The rotation axis of the cutter disc 3 and the length direction of the base 1 are parallel to each other. A plurality of limiting spaces 31 for inserting a tool 4 are provided on the surface of the cutter disc 3. The spindle 2 is slidably connected to the top surface of the base 1. The sliding direction of the spindle 2 and the rotation axis of the cutter disc 3 are perpendicular to each other. A mounting seat 5 is slidably connected to the surface of the spindle 2 away from the base 1. The sliding direction of the mounting seat 5 and the rotation axis of the cutter disc 3 are parallel to each other, and the mounting seat 5 is for installing the tool 4.

[0032] Reference Figure 1 and Figure 2 When it is necessary to install the tool 4 on the mounting seat 5, the cutter disc 3 rotates, the corresponding tool 4 faces the spindle 2, the spindle 2 slides along the surface of the base 1 toward the cutter disc 3, the mounting seat 5 faces the corresponding tool 4, the mounting seat 5 slides along the surface of the spindle 2 toward the tool 4, and the tool 4 is embedded in the mounting seat 5, so as to realize the directional replacement of the tool 4 on the mounting seat 5, without the need to set up a special tool changing mechanism, reducing the tool changing steps for the mounting seat 5, shortening the processing cycle of the product, and thus improving the processing efficiency of the product.

[0033] Reference Figure 1 and Figure 2 A storage cavity 11 for accommodating the cutter disc 3 is provided on the top surface of the base 1. The storage cavity 11 penetrates the outer wall of the base 1 in the direction close to the spindle 2. A storage plate 6 covering the storage cavity 11 is embedded on the surface of the base 1, so that the cutter 4 of the cutter disc 3 in the storage cavity 11 is not easily damaged by external impact, thereby extending the service life of the cutter 4; a handle 7 is fixed on the surface of the storage plate 6 away from the storage cavity 11, and the handle 7 provides a force point for the staff, so that the staff can control the opening and closing of the storage cavity 11 by the storage plate 6 conveniently.

[0034] Reference Figure 2 and Figure 3The cutter disc 3 includes a rotating part 32, a power motor 33, a support part 34, a sealing plate 35 and a plurality of spring clips 36. The support part 34 is fixed to the inner wall of the storage cavity 11 by bolts, and the power motor 33 is fixed to the surface of the support part 34 by bolts. The end of the motor shaft of the power motor 33 passes through the surface of the support part 34 and is coaxially welded and fixed to the surface of the rotating part 32. In the embodiment of the present application, the rotating part 32 is an arc-shaped plate, and the rotating part 32 includes an arc-shaped surface and a flat surface. A plurality of spring clips 36 are connected to the surface of the arc-shaped plate at intervals, and a plurality of spring clips 36 surround the arc-shaped surface, and the limiting space 31 is located on the spring clip 36.

[0035] Reference Figure 2 and Figure 3 The sealing plate 35 is welded and fixed on the flat surface. When the tool 4 is embedded in the mounting seat 5, the spindle 2 slides in the direction away from the rotating part 32, and the tool 4 squeezes the spring buckle 36. The spring buckle 36 is deformed under pressure, and the deformation space becomes larger, and the tool 4 is separated from the deformation space, thereby realizing the separation of the tool 4 and the spring buckle 36; at the same time, the power motor 33 drives the rotating part 32 to rotate, and the sealing plate 35 rotates in the direction close to the spindle 2. The circumferential outer wall of the sealing plate 35 presses against the inner wall of the storage cavity 11 to form a seal, thereby realizing the directional closure of the storage cavity 11, so that the debris generated by the tool 4 on the mounting seat 5 for processing the product is not easy to enter the storage cavity 11, thereby ensuring the cleanliness of the storage cavity 11, and making the tool 4 on the cutter disc 3 in the storage cavity 11 not easily interfered, thereby ensuring the processing accuracy of the tool 4 on the product.

[0036] The implementation principle of a tool changing structure of a tool magazine in the embodiment of the present application is as follows: when it is necessary to install a tool 4 on the mounting seat 5, the cutter disc 3 rotates, the corresponding tool 4 faces the spindle 2, the spindle 2 slides along the surface of the base 1 toward the cutter disc 3, the mounting seat 5 faces the corresponding tool 4, the mounting seat 5 slides along the surface of the spindle 2 toward the tool 4, the tool 4 is embedded in the mounting seat 5, the spindle 2 slides in the direction away from the rotating part 32, the tool 4 squeezes the spring buckle 36, the spring buckle 36 is deformed under pressure, the deformation space becomes larger, the tool 4 is separated from the deformation space, the tool 4 is separated from the spring buckle 36, and the tool 4 on the mounting seat 5 is changed. Directional replacement does not require the installation of a special tool changing mechanism, which reduces the tool changing steps for the mounting seat 5, shortens the processing cycle of the product, and thus improves the processing efficiency of the product; at the same time, the power motor 33 drives the rotating part 32 to rotate, and the sealing plate 35 rotates in the direction close to the main shaft 2, and the circumferential outer wall of the sealing plate 35 presses against the inner wall of the storage chamber 11 to form a seal, thereby achieving directional closure of the storage chamber 11, making it difficult for the tool 4 on the mounting seat 5 to generate debris during product processing to enter the storage chamber 11, thereby ensuring the cleanliness of the storage chamber 11, and making it difficult for the tool 4 on the cutter disc 3 in the storage chamber 11 to be interfered with, thereby ensuring the processing accuracy of the tool 4 on the product.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
