DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, the utility model provides a technical solution: a tool changing device for a CNC machine tool, comprising a support arm 1, a multi-position plate 2 is arranged inside the support arm 1, a connecting plate 3 is clamped inside the multi-position plate 2, a plurality of tool bodies 4 are connected inside the connecting plate 3, a guide rod 5 is connected inside the multi-position plate 2, a telescoping device 16 is connected to the support arm 1, two fixing blocks 7 are connected outside the connecting plate 3, and a threaded rod 8 is rotatably connected to one side of the multi-position plate 2;

[0020] By setting a multi-position plate 2, two different tool bodies 4 are installed in the multi-position plate 2, and the tool body 4 can be driven by the multi-position plate 2 to perform conversion processing, and the multi-position plate 2 can replace the unused tool body 4 without waiting for the CNC machine tool to stop operating;

[0021] The guide rod 5 is rotatably connected in the support arm 1, and a gear 6 is connected to the outside of the guide rod 5. By setting the guide rod 5, when the multi-position plate 2 is affected by external force factors, the multi-position plate 2 will rotate in the support arm 1 with the guide rod 5 as the center, so that the guide rod 5 plays a certain positioning role in the rotation of the multi-position plate 2, avoiding collision of the multi-position plate 2 during rotation;

[0022] A slide groove 13 is provided on the support arm 1, and a tooth plate 14 is slidably connected in the slide groove 13. An auxiliary block 15 is connected to one side of the tooth plate 14. The auxiliary block 15 is connected to the telescopic device 16. The tooth plate 14 is meshed with the gear 6, and the tooth plate 14 is located between the auxiliary block 15 and the guide rod 5. By setting the slide groove 13, when the auxiliary block 15 is subjected to thrust or tension, the tooth plate 14 will be driven to slide in the slide groove 13, so that the slide groove 13 plays a certain guiding role in the movement of the tooth plate 14, thereby preventing the tooth plate 14 from getting stuck when moving;

[0023] The threaded rod 8 is externally threadedly connected to a movable plate 9, and a mounting plate 10 is connected to one side of the movable plate 9. A slot 11 is provided in the multi-position plate 2, and a mounting slot 12 is provided in the fixed block 7. The fixed block 7 is snapped into the slot 11, and the mounting plate 10 is snapped into the mounting slot 12. By setting the slot 11, when the knife body 4 is connected to the multi-position plate 2, the fixed block 7 above the connecting plate 3 will be snapped into the slot 11, so that the slot 11 plays a certain limiting role in the fixation of the knife body 4, thereby avoiding the position displacement of the knife body 4 during connection.

[0024] The working principle of the utility model is:

[0025] When the tool is connected to the support arm 1, different tool bodies 4 can be snapped into the multi-position plate 2 in sequence. When the tool body 4 is snapped into the multi-position plate 2 through the connecting plate 3, the fixed block 7 above the tool body 4 will be snapped into the slot 11, and then the movable plate 9 will be driven to move by the threaded rod 8, and the mounting plate 10 will move with the movable plate 9, and the mounting plate 10 will be interlaced with the mounting slot 12, and the connecting plate 3 will be snapped into the multi-position plate 2. When different tools are needed, the tool body 4 can apply thrust or pull to the auxiliary block 15, and the tooth plate 14 will slide in the slide groove 13. Since the slide groove 13 is meshed with the gear 6, the multi-position plate 2 will rotate around the guide rod 5, and the multi-position plate 2 will rotate other tools to the appropriate position after rotation.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
