如圖2所示，各刀片座結構40係各自包括有一刀片座41、一牙套42及一固定螺栓43，由於各刀片座41、各牙套42以及各固定螺栓43的形狀與構造相同，因此以下僅以單個刀片座41、單個牙套42以及單個固定螺栓43來作說明：該刀片座41大致呈矩形的塊狀且具有一上端面、一下端面、二側面、一前面及一後面，該刀片座41包括有一刀片座抵面411、一刀刃412、一V形抵靠部413及一刀片座固定螺孔414，該刀片座抵面411係為斜度配合該楔塊斜面312的斜面，且該刀片座抵面411設置於該刀片座41的上端面，該刀刃412則設在該刀片座41的下端面且具有一銑削面，該V形抵靠部413係匹配該刀頭10的V槽123且設置於其中一該側面，該銑削面與該V形抵靠部413的方向相反；該牙套42的外徑係配合該刀頭10的牙套孔124來設置，該牙套42並具有一外螺紋及一內螺紋；該固定螺栓43係為星型螺栓且所設的螺牙係配合該牙套42的內螺紋來設置；安裝各刀片座結構40時，首先將各牙套42旋入該刀片座10的牙套孔124，將各刀片座40的V形抵靠部413對正該刀頭10所設的各V槽123並將各刀片座40由該刀頭10的下方置入各刀片座安裝孔121，再以各固定螺栓43鎖入各牙套42的內螺紋並使該刀片座抵面411抵靠於該楔塊斜面312，即完成各刀片座結構40的安裝。As shown in FIG. 2, each of the blade holder structures 40 includes a blade holder 41, a mouthpiece 42 and a fixing bolt 43. Since each blade holder 41, each of the sleeves 42 and the fixing bolts 43 have the same shape and configuration, the following Only a single blade holder 41, a single braces 42 and a single fixing bolt 43 are illustrated: the blade holder 41 has a substantially rectangular block shape and has an upper end surface, a lower end surface, two side surfaces, a front surface and a rear surface. The 41 includes a blade seating surface 411, a cutting edge 412, a V-shaped abutting portion 413, and a blade holder fixing screw hole 414. The blade seat abutting surface 411 is a slope that obliquely fits the wedge slope 312, and the The blade seat abutting surface 411 is disposed on the upper end surface of the blade holder 41. The blade edge 412 is disposed on the lower end surface of the blade holder 41 and has a milling surface. The V-shaped abutting portion 413 matches the V-groove of the blade head 10. 123 is disposed on one of the sides, the milling surface is opposite to the V-shaped abutting portion 413; the outer diameter of the braces 42 is disposed to fit the sleeve hole 124 of the cutting head 10, and the dental sleeve 42 has an outer portion Thread and an internal thread; the fixing bolt 43 is a star bolt and The threaded teeth are arranged to match the internal threads of the dental mouthpiece 42. When each of the blade seat structures 40 is mounted, each of the dental mouthpieces 42 is first screwed into the socket hole 124 of the blade holder 10, and the V-shape of each blade holder 40 is abutted. The portion 413 is opposite to each of the V grooves 123 provided in the cutting head 10, and each of the insert holders 40 is placed in the respective blade holder mounting holes 121 from the lower side of the cutter head 10, and is locked into the respective sleeves 42 by the respective fixing bolts 43. Threading and abutting the blade seat abutment surface 411 against the wedge ramp 312 completes the mounting of each blade holder structure 40.
如圖5所示，本創作所提供之可穩定切削加工之銑刀係結合於銑床的主軸，在對工件進行高速銑削時，工件與該刀片座結構40之間的反作用力透過該刀片座41的V形抵靠部413傳遞至該刀頭10的V槽123，藉此來降低該刀片座結構40的切削力，與圖6所示的現有銑刀相比，現有的銑刀僅以單一吸收面來吸收切削力，而本創作在各刀片座安裝孔121的V槽123設計增加了該刀片座41與該刀頭10之間的接觸面積，使該刀頭10能有效率地補償銑削所帶來的切削力，除了幫助操作者穩定地銑削工件、提高工件的加工精度之外，更能延長刀片座41的使用壽命。As shown in FIG. 5, the milling cutter capable of stable cutting is provided in the main shaft of the milling machine. When the workpiece is subjected to high-speed milling, a reaction force between the workpiece and the insert base structure 40 is transmitted through the insert seat 41. The V-shaped abutting portion 413 is transmitted to the V-groove 123 of the cutter head 10, thereby reducing the cutting force of the insert base structure 40. Compared with the existing milling cutter shown in Fig. 6, the existing milling cutter is only a single The absorption surface absorbs the cutting force, and the design of the V-groove 123 of each blade mounting hole 121 increases the contact area between the blade holder 41 and the cutter head 10, so that the cutter head 10 can efficiently compensate for the milling. The cutting force brought in, in addition to helping the operator to stably mill the workpiece and improve the machining accuracy of the workpiece, can further extend the service life of the insert seat 41.
在最佳實施例中，該等動平衡螺栓20、調整結構30及刀片座結構40的數目可視情況而調整，該等刀片座安裝孔12、楔塊安裝孔13及動平衡螺孔15的數目係對應該等動平衡螺栓20、調整結構30及刀片座結構40的數目來設置，本創作對於這些構造的數目不做特別限定。In a preferred embodiment, the number of the balance weight bolts 20, the adjustment structure 30, and the blade holder structure 40 can be adjusted as appropriate. The number of the blade holder mounting holes 12, the wedge mounting holes 13, and the dynamic balance screw holes 15 can be adjusted. The number of the balance bolts 20, the adjustment structure 30, and the blade holder structure 40 should be set equal to each other, and the number of these configurations is not particularly limited.
