[0041] Example 1: Refer to Figures 1-7, A modularly expandable disc-type tool magazine, comprising a tool magazine box 1. A tool changing port 11 is opened at the middle position below the tool magazine box 1. A plurality of moving frames 2 are slidably arranged in the tool magazine box 1. A disc-type tool holder 3 is rotatably arranged in the moving frame 2. A moving component 5 for horizontally moving the plurality of moving frames 2 is arranged on the tool magazine box 1. The lower part of the moving frame 2 is open. A rotating shaft 4 is horizontally rotatably arranged at the middle position in the tool magazine box 1. One end of the rotating shaft 4 is drivingly connected with a motor 41. The tool holder 3 includes a shaft cylinder 31. One end of the outer wall of the shaft cylinder 31 is rotatably connected with the central position of the moving frame 2 through a bearing. The inner wall of the shaft cylinder 31 is in sliding contact with the outer wall of the rotating shaft 4. A connecting mechanism 35 for connecting with the rotating shaft 4 is arranged on the shaft cylinder 31. Thus, a plurality of tool holders 3 mounted on their respective moving frames 2 are arranged in the tool magazine box 1. The plurality of tool holders 3 can horizontally move along the tool magazine box 1 through the moving component 5. During the movement, the connecting mechanism 35 in the tool holder 3 is not connected with the rotating shaft 4, so as to ensure that the tool holder 3 moves with the moving frame 2. When controlling and selecting the corresponding tool head, the tool holder 3 and the moving frame 2 where the corresponding tool head is located are moved to the position corresponding to the tool changing port 11. Then, the connecting mechanism 35 on the shaft cylinder 31 is connected with the rotating shaft 4. Thus, the rotating shaft 4 can be rotated by the motor 41 to drive the tool holder 3 to rotate, so as to rotate the tool head to be selected to the lower position corresponding to the tool changing port 11, so as to perform tool selection or tool changing operations. Through the arrangement of a plurality of tool holders 3 in the tool magazine box 1, the tool storage capacity of the disc-type tool magazine can be increased. And the tool storage capacity can be further increased by adding a set of moving frame 2 and tool holder 3 for modular expansion, so as to effectively improve the applicability and expansion convenience of the disc-type tool magazine.

[0042] In the present invention, referring to Figures 1-7 , the tool magazine box 1 includes a box frame 101, a first box cover 102 and a second box cover 103. The first box cover 102 and the second box cover 103 are respectively arranged at both ends of the box frame 101. The first box cover 102 is located at one end of the box frame 101 close to the motor 41. The housing of the motor 41 is fixed to the outer wall of the first box cover 102. The second box cover 103 is located at one end of the box frame 101 far from the motor 41. A connecting frame 104 is detachably connected between the box frame 101 and the first box cover 102, and between the box frame 101 and the second box cover 103, that is, the box frame 101 and the connecting frame 104, the connecting frame 104 and the first box cover 102, the connecting frame 104 and the second box cover 103, and the connecting frame 104 and the connecting frame 104 are all detachably connected. It should be noted that: the tool changing port 11 is arranged at the middle position of the bottom end of the box frame 101. The side inner walls of the box frame 101, the connecting frame 104, the first box cover 102 and the second box cover 103 are flush.

[0043] In the present invention, referring to Figures 1-7, the rotating shaft 4 includes a central shaft 401, a drive shaft 402 and a positioning shaft 403. Connecting shafts 404 are detachably connected between the central shaft 401 and the drive shaft 402, and between the central shaft 401 and the positioning shaft 403. One end of the drive shaft 402 away from the central shaft 401 is connected to the output shaft of the motor 41. The outer walls of the central shaft 401, the connecting shaft 404, the drive shaft 402 and the positioning shaft 403 are flush; it should be noted that: clamping grooves one are provided at both ends of the central shaft 401. One end of the connecting shaft 404 facing the central shaft 401 is provided with a clamping block one. A clamping groove two is provided at one end of the connecting shaft 404 away from the central shaft 401. One ends of the drive shaft 402 and the positioning shaft 403 facing the central shaft 401 are both provided with clamping blocks two. The clamping block one can be clamped with the clamping groove one, and the clamping block two can be clamped with both the clamping groove one and the clamping groove two; further it should be noted that: the drive shaft 402 is rotatably connected with the first box cover 102, and the positioning shaft 403 is rotatably connected with the second box cover 103;

[0044] Thus, when modularly expanding the tool rest 3, open the first box cover 102 and the second box cover 103 from both ends. The first box cover 102 will drive the drive shaft 402 to disengage, and the second box cover 103 will drive the positioning shaft 403 to disengage. Then add a set of connecting frames 104 and connecting shafts 404 at both ends, place a set of moving frames 2 and tool rests 3 along the outer wall of the connecting shaft 404 and the inner wall of the connecting frame 104, and make the added moving frames 2 abut against the adjacent moving frames 2 and then connect with the moving assembly 5. Then close the first box cover 102 and the drive shaft 402, and the second box cover 103 and the positioning shaft 403, and update the corresponding control program accordingly to complete the expansion of the tool magazine; thus effectively improving the effectiveness of the modular expansion of the tool magazine, increasing the adaptability of the tool storage capacity of the tool magazine and the convenience of expansion.

[0045] In the present invention, with reference to Figures 1-7, the moving component 5 includes an electric control guide rail 51 and a clamping member 52 connected to the electric control guide rail 51. The two ends of the clamping member 52 clamp and fix a plurality of moving frames 2 in the middle. It should be noted that: the electric control guide rail 51 is fixed to the top of the box frame 101, and placing frames are installed at both ends of the electric control guide rail 51, and the bottom of the placing frame can be abutted against the top of the connection frame 104, or the first box cover 102, or the second box cover 103; further it should be noted that: the clamping member 52 includes a horizontal frame and clamping blocks at both ends of the horizontal frame. The clamping blocks are detachably connected to the horizontal frame, and extension frames are also detachably installed between the clamping blocks and the horizontal frame, so as to adaptively change the clamping member 52 according to the actual number of moving frames 2 and tool holders 3 placed, so as to simultaneously move a plurality of tool holders 3 through the electric control guide rail 51. A through slot 14 is opened at the top of the tool magazine box 1. It should be noted that: the through slot 14 extends in the horizontal direction, and the through slot 14 is provided on the box frame 101 and the connection frame 104, that is, both the box frame 101 and the connection frame 104 are provided with through slots 14 that penetrate at both ends and extend horizontally; a magnetic block 23 is embedded at one end of the moving frame 2, so that when adjacent two moving frames 2 are abutted, they are magnetically adsorbed between the magnetic block 23 and the corresponding housing, so as to ensure the stability of the integrated horizontal movement of a plurality of moving frames 2.

[0046] In the present invention, with reference to Figures 1-12 , a plurality of connecting frames 32 distributed in an annular array are installed on the circumferential outer wall of the shaft cylinder 31. An installation frame 33 is fixed to the end of the connecting frame 32 far from the shaft cylinder 31. A tool sleeve 34 is rotatably connected to the position of the installation frame 33 far from the connecting frame 32 through a torsion spring; on one side of the tool changing port 11, there is a tool output driving assembly 7. The tool output driving assembly 7 includes an electric push rod 71 extending vertically upward, and a push block 72 is installed at the top of the electric push rod 71; it should be noted that: the housing of the electric push rod 71 is installed at the bottom of the box frame 101 on one side of the tool changing port 11, and the telescopic shaft of the electric push rod 71 extends axially into the tool magazine box 1, and the push block 72 is installed at the end of the telescopic shaft of the electric push rod 71; further it should be noted that: when the tool holder 3 rotates step by step along with the rotating shaft 4, each step rotation makes one of the tool sleeves 34 located directly above the tool changing port 11. The tool sleeve 34 located directly above the tool changing port 11 is horizontally placed in the normal state, and the opening position of the tool sleeve 34 for placing the tool head is located in the direction of the end of the installation frame 33 far from the push block 72; during use, when the tool sleeve 34 to be selected moves to directly above the tool changing port 11, the electric push rod 71 moves the push block 72 upward, so that the push block 72 presses one end of the tool sleeve 34, and the tool sleeve 34 drives the tool head to deflect downward and extend out of the tool changing port 11, so as to perform tool selection or tool changing operations.

[0047] In the present invention, with reference to Figures 1-13, the connecting mechanism 35 includes a connecting box 351 installed on the outer wall of the shaft cylinder 31. The bottom end of the connecting box 351 is open. A spring 352 is fixed to the inner wall of the top of the connecting box 351. The bottom end of the spring 352 is fixed with a connecting block 353. The connecting block 353 is made of a magnetic material. A through hole 311 is opened at the position on the outer wall of the shaft cylinder 31 corresponding to the connecting block 353. It should be noted that: a connecting mechanism 35 is provided in each tool rest 3. Under normal conditions, the connecting block 353 is located between the through hole 311 and the connecting box 351. Even when the connecting box 351 is directly above and the connecting block 353 naturally hangs down to the maximum distance away from the connecting box 351, the connecting block 353 will not extend into the rotating shaft 4, so as to ensure the effectiveness of the tool rest 3 during the horizontal movement along with the moving frame 2.

[0048] In the present invention, referring to Figures 1-13 , a cavity is provided inside the rotating shaft 4. One end of the cavity far from the motor 41 is open. A through port 42 is opened on the inner side of the cavity. The outer wall of the connecting block 353 is in sliding contact with the inner wall of the connecting box 351, the inner wall of the through hole 311, and the inner wall of the through port 42. An electromagnetic block 44 is provided at the position in the cavity corresponding to the through port 42. An extension rod 43 is installed at one end of the electromagnetic block 44 far from the motor 41. An installation plate 431 is installed at one end of the extension rod 43 far from the electromagnetic block 44. The installation plate 431 is detachably connected to the second box cover 103. It should be noted that: the cavity extends in the central axis 401, the connecting shaft 404, and the positioning shaft 403, and both ends of the cavity in the positioning shaft 403 are open. The electromagnetic block 44 is horizontally inserted into the cavity from the direction of the positioning shaft 403 and fixed through the installation plate 431, so that the electromagnetic block 44 is in the cavity but does not rotate with the rotating shaft 4;

[0049] Furthermore, it should be noted that: the positions of the electromagnetic block 44 and the through port 42 are relatively fixed. Before each selection of the tool rest 3, the rotating shaft 4 will rotate to a fixed position: for example, the through port 42 is rotated to face upward; then the selected tool rest 3 is moved to the corresponding position to connect the through hole 311 and the through port 42. After the electromagnetic block 44 is energized, it will magnetically attract the connecting block 353 downward, and the connecting block 353 will extend into the through port 42. The connecting block 353 will simultaneously contact the inner walls of the through hole 311 and the through port 42, so that the rotating shaft 4 can drive the corresponding tool rest 3 to rotate; during the rotation process, the electromagnetic block 44 always remains charged to maintain the stability of the connection between the rotating shaft 4 and the corresponding shaft cylinder 31; when replacing the tool rest 3, first rotate the rotating shaft 4 with the tool rest 3 to the fixed position, and then cut off the power supply of the electromagnetic block 44, so that the connecting mechanism 35 in the unselected tool rest 3 always remains in the fixed position, which is convenient for quick connection next time.

[0050] Embodiment 2: Referring to Figures 1-13, A modularly expandable disc tool magazine. On the basis of Embodiment 1, a limiting mechanism 24 is provided on the moving frame 2, and is connected to the tool holder 3 through the limiting mechanism 24 when the moving frame 2 and the tool holder 3 move horizontally; the limiting mechanism 24 includes a cylinder 1 241 installed on the moving frame 2. The cylinder 1 241 is placed horizontally, and a limiting block 242 is connected to the end of the cylinder 1 241 facing the tool holder 3. When the moving frame 2 and the tool holder 3 move horizontally, the cylinder 1 241 is extended to make the limiting block 242 press against the tool holder 3, so that the tool holder 3 and the moving frame 2 are limited and fixed, and the tool holder 3 is stably placed relative to the moving frame 2. In this way, during the horizontal movement of the moving frame 2 and the tool holder 3, the shaft cylinder 31 of the tool holder 3 will not deflect relative to the rotating shaft 4, thus ensuring the accuracy and stability of the connection and selection during the use of the tool holder 3;

[0051] It should be noted that: a limiting groove 321 is opened in the direction of the connecting frame 32 facing the limiting mechanism 24, and the limiting block 242 is in sliding contact with the inner wall of the limiting groove 321; thus, after the corresponding tool holder 3 is no longer connected to the rotating shaft 4, the limiting groove 321 on the side of the connecting frame 32 in the upper middle position just corresponds to the position of the limiting block 242 in the moving frame 2. When the cylinder 1 241 extends, the limiting block 242 can be extended into the limiting groove 321, so as to ensure the stability of the connection between the tool holder 3 and the moving frame 2 during the horizontal movement, and prevent the tool holder 3 from slipping and deflecting during the horizontal movement, which may affect the next tool change operation.

[0052] In the present invention, referring to Figures 1-13 , Sliders 1 22 are installed on both sides of the moving frame 2, and horizontal extension sliding grooves 1 13 are opened at positions on the inner wall of the tool magazine box 1 corresponding to the sliders 1 22. It should be noted that: the sliding grooves 1 13 extend horizontally on the inner walls of the box frame 101 and the connecting frame 104; rolling balls 222 are arranged on the top and bottom outer walls of the sliders 1 22, and the outer walls of the rolling balls 222 are in rolling contact with the inner walls of the sliding grooves 1 13; further, sliders 2 21 are fixed at other positions on the outer wall of the moving frame 2, and horizontal extension sliding grooves 2 12 are opened at positions on the inner wall of the tool magazine box 1 corresponding to the sliders 2 21. Through the sliding contact between the sliders 2 21 and the sliding grooves 2 12, and the limited movement of the sliders 1 22 and the rolling balls 222 in the sliding grooves 1 13, the stability and anti-offset effect of the moving frame 2 during the horizontal movement are ensured, and the rolling balls 222 are used to ensure the stability of the horizontal movement.

[0053] In the present invention, referring to Figures 1-14, a stabilizing component 6 is arranged at the middle positions on both sides of the tool magazine box 1. It should be noted that: the stabilizing component 6 is installed on the outer wall of the box frame 101, and after the moving frame 2 stops moving, the stabilizing component 6 corresponds to the position of the corresponding slider one 22; the stabilizing component 6 includes a fixed frame 61, the fixed frame 61 is fixedly installed on the outer wall of the tool magazine box 1, a cylinder two 62 is horizontally installed at the end of the fixed frame 61 facing the tool magazine box 1, a pressing block 63 is connected to the end of the cylinder two 62 facing the tool magazine box 1, a perforation is opened at the position on the outer wall of the tool magazine box 1 corresponding to the pressing block 63, a pressing groove 221 is opened on the outer side of the slider one 22, the pressing block 63 is adapted to the pressing groove 221. During the movement of the moving frame 2, the cylinder two 62 drives the pressing block 63 to contract to ensure the effectiveness of the movement of the moving frame 2. During the tool change operation, the cylinder two 62 drives the pressing block 63 to extend into the tool magazine box 1, so that the pressing block 63 passes through the perforation and extends into the pressing groove 221 of the slider one 22, thereby improving the stability of the moving frame 2 during the tool change process to ensure the stability during the rotation tool change of the tool rest 3, avoiding shaking and deviation from affecting the service life of the equipment, and avoiding shaking from affecting the accuracy and effectiveness of the tool change.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
