DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-6A gantry milling machine capable of rapid tool change comprises a gantry milling machine body 1, a spindle box 11 being provided on the gantry milling machine body 1, a drive shaft 12 being rotatably provided at the bottom of the spindle box 11, a detachable mounting sleeve 2 being mounted on the drive shaft 12, and a milling cutter assembly 21 being mounted at the bottom of the mounting sleeve 2. A plurality of mounting members 13 for securing the mounting sleeve 2 are movably provided at the bottom of the drive shaft 12, and mounting cavities 23 are adapted to be formed on the mounting sleeve 2 corresponding to the mounting members 13, and a mounting sleeve 3 is rotatably provided on the outer side of the mounting sleeve 2.

[0022] The multiple slide rails on the gantry milling machine body 1 can drive the spindle box 11 to move, and the drive mechanism within the spindle box 11 can drive the drive shaft 12. It is also worth noting that the specific structure and operating method of the gantry milling machine body 1 and the spindle box 11 are all existing technologies currently available on the market. They are common knowledge well known to those skilled in the art and do not constitute the main technical problem to be solved by the present technical solution. Therefore, they are not described in detail in this utility model.

[0023] Among them, the top of the mounting sleeve 2 is fixedly provided with a clamping column 4, and the upper corresponding clamping column 4 is adapted to open a clamping cavity 41 on the drive shaft 12. The adaptive clamping arrangement between the clamping column 4 and the clamping cavity 41 can ensure the synchronous rotation between the mounting sleeve 2 and the milling cutter assembly 21 and the drive shaft 12.

[0024] The bottom of the drive shaft 12, located around the card cavity 41, is provided with movable grooves 15, and movable blocks 14 are movably mounted within the movable grooves 15. Both sides of the top of the mounting member 13 are fixedly connected to the bottom of the movable blocks 14, and the mounting member 13 is moved by the movable blocks 14. The provision of the movable blocks 14 ensures smooth movement of the mounting member 13 at the bottom of the drive shaft 12. Furthermore, anti-drop blocks are fixedly mounted on the top of the movable blocks 14 to prevent the movable blocks 14 from falling out of the movable grooves 15.

[0025] The mounting sleeve 2 has a plurality of sub-cavities 24 extending upwardly from the top of the mounting cavity 23, and each of the sub-cavities 24 is adapted to fit within the movable block 14. The provision of the sub-cavities 24 ensures that the movable block 14 is not obstructed by the mounting sleeve 2 during the engagement of the mounting member 13 with the mounting cavity 23.

[0026] The mounting sleeve 3 has an internal thread 31, and the mounting sleeve 2 has an external thread groove 32 corresponding to the internal thread 31. Furthermore, the mounting sleeve 2 has a plurality of support members 22 fixedly mounted on the bottom of the mounting sleeve 3. The mounting sleeve 3 can be used to limit the position of the mounted member 13, thereby improving the stability of the device after assembly.

[0027] In this embodiment, when the user needs to replace the milling cutter assembly 21, the mounting sleeve 2 can be removed from the drive shaft 12, and then the mounting sleeve 2 with other milling cutter assemblies 21 can be replaced on the drive shaft 12, thereby achieving the replacement of the milling cutter assembly 21.

[0028] Furthermore, when the user needs to disassemble the milling cutter assembly 21, they simply rotate the mounting sleeve 3 downward through the thread until it contacts the support member 22. This exposes the mounting cavity 23 and the auxiliary cavity 24 on the mounting sleeve 2. The user can then insert the locking column 4 at the top of the mounting sleeve 2 into the locking cavity 41 on the drive shaft 12. The mounting members 13 are then aligned with the mounting cavities 23, and each of the mounting members 13 is inserted into the mounting cavities 23. Finally, the mounting sleeve 3 is rotated upward so that the inner wall of the mounting sleeve 3 engages all of the mounting members 13. This allows the mounting sleeve 2 and milling cutter assembly 21 to be assembled by locking the mounting members 13.

[0029] Furthermore, when the user needs to disassemble the milling cutter assembly 21, he only needs to rotate the mounting sleeve 3 on the mounting sleeve 2 downward so that the mounting sleeve 3 contacts the support member 22 again. At this time, the mounting member 13 stuck in the mounting cavity 23 is exposed. The user only needs to pick out all the mounting members 13 from the mounting cavity 23, so as to realize the disassembly of the milling cutter assembly 21 and the mounting sleeve 2, which is very convenient.

[0030] In the present invention, the mounting sleeve 2 can be assembled on the drive shaft 12 through the adapter between the mounting member 13 and the mounting cavity 23. This assembly method is fast and convenient, and does not require the use of external auxiliary tools, allowing the user to quickly replace the milling cutter assembly 21 on the gantry milling machine body 1, which is convenient for the user to use.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
