[0002] The end mill is one of the most used milling cutters on numerically controlled machine tools. In order to better machine different cutting surfaces, it is necessary to replace the cutter head. Generally, the cutter head is installed and disassembled by means of threaded connection. For example, an end mill with a rotatable and adjustable cutter head disclosed in the authorized publication number CN219616785U includes an end mill body, the tail end of the end mill body is fixedly connected with a mounting seat, a plurality of screw holes distributed along the circumferential direction are opened on the mounting seat, and further includes an adjusting base, a rotating plate is hinged in the middle of the adjusting base, a fixing seat is fixedly connected to the end of the rotating plate away from the adjusting base, and an embedding groove for embedding the mounting seat is opened on the end face of the fixing seat.

[0003] In this device, the cutter body is replaced by means of bolt connection. However, in the actual application process, the researchers found that this method requires a specific type of tool to disassemble the bolt, which is very inconvenient to use, cannot be quickly replaced conveniently, and is not conducive to popularization and use.

[0023] During use, first connect the fixed plate 1 to the driving mechanism through bolts, then insert the mounting seat 11 into the inner cavity of the fixed base 2, and then insert the insertion box 4 into the slot holes opened in the mounting seat 11 and the fixed base 2 to perform preliminary limiting on the mounting seat 11.

[0024] It should be noted that: when the insertion box 4 is completely inserted into the slot hole opened on the fixed base 2, that is, the convex position of the insertion box 4 is in sliding connection with the fixed base 2 in a fitting manner, at this time, the limiting rod 10 is aligned with the limiting hole 13 on the limiting box 3.

[0025] As a preferred technical solution of the novel quick-change cutter head type end mill of the present utility model, slot holes matching the structural dimensions of the insertion box 4 are respectively and penetratingly provided on one side surface of the fixed base 2 and one side surface of the mounting seat 11, and a groove matching the structural dimensions of the mounting seat 11 is provided on the bottom surface of the fixed base 2; this ensures that the insertion box 4 can penetrate through the fixed base 2 and the mounting seat 11.

[0026] As a preferred technical solution of the novel quick-change cutter head type end mill of the present utility model, limiting holes 13 are provided on the opposite side surfaces of the two limiting boxes 3, and the limiting holes 13 match the structural dimensions of the limiting rods 10; the limiting rods 10 are inserted into the limiting holes 13 for position limitation.

[0027] As a preferred technical solution of the novel quick-change cutter head type end mill of the present utility model, the vertical section of the insertion box 4 is in a T-shaped structure, and slot holes matching the structural dimensions of the limiting rods 10 are respectively and penetratingly provided on the top surface and the bottom surface of the insertion box 4; when one side surface of the baffle 6 is in sliding connection with the insertion box 4 in a fitting manner, at this time, the movement screw 5 moves to the rightmost extreme position, and at this time, the opposite ends of the two limiting rods 10 are flush with the top surface of the insertion box 4, that is, during the movement of the movement screw 5, the limiting rods 10 are always in a state of being inserted, engaged, and slidingly connected with the insertion box 4, preventing the situation where the movement screw 5 rotates and drives the triangular block 8 to rotate. Embodiment

[0028] Please refer to Figure 3 、 Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that:

At this time, as the movement screw rod 5 rotates, the triangular block 8 moves, the combination of the fitting plate 9 and the limiting rod 10 slides on the triangular block 8, and the limiting rod 10 gradually extends and is inserted into the limiting hole 13, so as to quickly limit the position of the tool body 12, and the operation is more convenient.
