The milling cutter is a very important machining accessory during the operation of numerical control machining equipment, and is widely used. Moreover, there are various types of milling cutters, and different milling cutters are used for different milling methods. For example, when performing face milling on a workpiece, a face milling cutter is required;
[0003] For some traditional face milling cutters, the tailstock and the cutter head are mostly in an integrated fixed structure form. During milling operations, different types of milling cutters often need to be replaced according to different milling methods. Therefore, more integral tools need to be prepared additionally. At the same time, when replacing, the milling cutter needs to be disassembled from the spindle and a new milling cutter needs to be installed each time. The increased number of disassembly and assembly operations will increase wear, and each time of disassembly and assembly requires operating the spindle chuck to clamp the tool, and there is also a lack of convenience in operation. In addition, the form of the milling cutter with an integrated tool handle and cutter head is inconvenient for regular storage when being stored, affected by the handle rod.

[0027] Refer to Figures 1-5, an embodiment provided by the present utility model: A milling cutter includes a milling cutter body 1. The milling cutter body 1 comprises a milling cutter shank 2 and a milling cutter head 3. One end of the milling cutter shank 2 is fixedly connected with a connecting piece 4. An activity groove 5 is arranged inside the connecting piece 4. A moving block 6 is nested and slidably connected inside the activity groove 5. One side of the outer surface of the moving block 6 is fixedly connected with a locking block 7. One end of the locking block 7 penetrates through the inner wall of the activity groove 5 and extends to the outside of the connecting piece 4. A regulating screw 8 is rotatably connected inside the connecting piece 4. A threaded groove 9 that is in threaded cooperation with the regulating screw 8 is arranged on the moving block 6. One end of the regulating screw 8 is fixedly connected with a rotating wheel 10. The rotating wheel 10 is located at the outside of the connecting piece 4. Grasping the rotating wheel 10 and rotating it can drive the regulating screw 8 to rotate. The regulating screw 8, in cooperation with the arrangement of the threaded groove 9, can drive the moving block 6 to move, thereby driving the locking block 7 to move. With the entire structure, it is convenient to carry out the docking and fixed installation between the connecting piece 4 and the milling cutter head 3. A milling cutter blade 12 is arranged on the milling cutter head 3, and a connecting groove 13 is arranged at the center of the milling cutter head 3. A locking groove 14 is arranged on the inner wall of the connecting groove 13. The connecting piece 4 and the connecting groove 13 are in a nested fit arrangement. The locking block 7 and the locking groove 14 are in a nested fit arrangement. The structures are docked in the form of a clearance nested fit, which can ensure the stability of the connection. The cooperation of structures such as the connecting piece 4, the connecting groove 13, the locking block 7, and the locking groove 14 can enable the milling cutter shank 2 and the milling cutter head 3 to be stably connected and fixed together, so as to carry out convenient and stable face milling work. At the same time, the structure can also be conveniently disassembled, which is convenient for replacing different types of milling cutter heads 3. The structure is simple to operate and flexible and convenient to use.
[0028] The cross-sections of the connecting piece 4 and the connecting groove 13 are both square. The square-structured connecting piece 4 and the connecting groove 13 can, after their docking, drive the milling cutter head 3 to rotate smoothly when the milling cutter shank 2 operates in cooperation with the spindle of the numerical control processing equipment, enabling it to operate and be used normally.
[0029] There are two sets of structures arranged for the activity groove 5, the moving block 6, the locking block 7, the threaded groove 9, and the locking groove 14. The thread directions on both sides of the regulating screw 8 are arranged in the opposite direction. The two threaded grooves 9 and the reverse threads on both sides of the regulating screw 8 are in corresponding threaded fit. The arrangement of the two sets of structures of the locking block 7 and the locking groove 14 can ensure the stability of the docking and installation of the connecting piece 4 and the milling cutter head 3. The two-way regulating screw 8 can drive the two moving blocks 6 to approach or move away from each other synchronously when rotating, thereby driving the locking block 7 to withdraw from or insert into the locking groove 14 to complete the stable disassembly and assembly operation of the structure.
[0030] Anti-slip convex lines are arranged on the outer side of the rotating wheel 10. The arrangement of the anti-slip convex lines can ensure the smoothness of the rotation operation of the rotating wheel 10.
[0031] A positioning disk 11 is nested and fixedly connected to the outer surface of the connecting member 4. A positioning groove 15 is provided on the outer surface of the milling cutter head 3 at a position corresponding to the connecting groove 13. The positioning disk 11 and the positioning groove 15 are nested and matched. The matching setting of the positioning disk 11 and the positioning groove 15 can assist in enhancing the stability and accuracy of the butt joint between the connecting member 4 and the milling cutter head 3.
[0032] Working principle: When using the milling cutter, insert the connecting member 4 into the connecting groove 13. At the same time, the positioning disk 11 is snapped into the positioning groove 15. Rotate the rotating wheel 10, and the rotating wheel 10 drives the adjusting screw 8 to rotate. The adjusting screw 8 drives the moving block 6 to move through the thread fit with the thread groove 9. The moving block 6 drives the locking block 7 to move and insert into the locking groove 14, and the butt joint between the connecting member 4 and the milling cutter head 3 can be completed, thus completing the butt joint and fixation between the milling cutter shank 2 and the milling cutter head 3. Install the milling cutter shank 2 into the spindle chuck of the machining equipment, and face milling can be carried out. Similarly, the milling cutter head 3 can be disassembled to facilitate the replacement of different types of milling cutter heads 3 for milling work.
