請參閱第1~3圖所示，本發明捨棄式環槽銑刀，包含一刀桿10，該刀桿10末端由一螺絲30鎖固一捨棄式環槽刀片20，其中：該刀桿10，於末端設有一刀槽座11，該刀槽座11得供一捨棄式環槽刀片20容置入，該刀槽座11之一隅設一呈半圓形狀之圓弧孔111，該圓弧孔111之一側設一螺孔12，該螺孔12其供螺絲頭31容置之錐形孔121係與該圓弧孔111之部位相互重疊過切。 Referring to FIGS. 1~3, the disposable ring groove milling cutter of the present invention comprises a cutter bar 10, and the end of the cutter bar 10 is locked by a screw 30 to a retractable ring groove cutter 20, wherein: the cutter bar 10, A slotted seat 11 is disposed at the end, and the slotted seat 11 is received by a discarding annular slotted blade 20, and one of the slotted seats 11 defines a circular arc hole 111 having a semicircular shape. The circular arc hole 111 One of the screw holes 12 is provided on the side of the screw hole 12, and the tapered hole 121 for receiving the screw head 31 and the portion of the circular arc hole 111 overlap each other.
該捨棄式環槽刀片20，包含一板狀之本體21，該本體21之一側延伸設一刀刃22，該本體21頂面之一側邊設有一半圓形狀之定位栓23， 該定位栓23之一側邊設一讓槽241，該讓槽241之末端設一斜推面242。 The retractable annular grooved blade 20 includes a plate-shaped body 21, and a blade edge 22 is extended on one side of the body 21. One side of the top surface of the body 21 is provided with a semicircular shape positioning pin 23. One side of the positioning pin 23 is provided with a slot 241, and an end of the slot 241 is provided with a tilting surface 242.
請參閱第1、4、5圖所示，本發明之捨棄式環槽刀片20置入 該刀桿10末端之刀槽座11內，藉由螺絲30螺入螺孔12時，該螺絲頭31將推頂捨棄式環槽刀片20之斜推面242，由該螺絲頭31與斜推面242之接觸點分析該捨棄式環槽刀片20承受朝下(-Z)、朝右(X)及前(Y)方向之推力，朝下(-Z)之推力使得該捨棄式環槽刀片20與刀槽座11之底面緊密接觸，而該朝右(X)之推力使得該捨棄式環槽刀片20之定位栓23與刀槽座11之圓弧孔111緊密接觸，而該朝前(Y)之推力使得該捨棄式環槽刀片20與刀槽座11緊密接觸，同時該捨棄式環槽刀片20受到螺絲頭31之推頂時，在該刀桿10之軸向與該刀槽座11緊密地接觸，據此，該捨棄式環槽刀片20與刀槽座11在3個軸向完全受到限制與固定。 Referring to Figures 1, 4, and 5, the disposable ring groove insert 20 of the present invention is placed. When the screw 30 is screwed into the screw hole 12 in the slot seat 11 at the end of the arbor 10, the screw head 31 pushes the oblique pushing surface 242 of the retractable ring groove blade 20, and the screw head 31 and the oblique push The contact point of the face 242 analyzes the thrust of the disposable ring groove blade 20 in the downward (-Z), right (X) and front (Y) directions, and the downward (-Z) thrust causes the disposable ring groove blade 20 is in close contact with the bottom surface of the sipe holder 11, and the thrust toward the right (X) causes the positioning pin 23 of the disposable ring groove blade 20 to be in close contact with the circular arc hole 111 of the sipe holder 11, and the forward direction ( The thrust of Y) causes the disposable ring groove insert 20 to be in close contact with the knife seat 11 while the disposable ring groove insert 20 is pushed by the screw head 31 in the axial direction of the cutter bar 10 and the cutter seat 11 is in close contact with each other, whereby the discarding ring groove insert 20 and the slotted seat 11 are completely restricted and fixed in three axial directions.
請參閱第6圖所示，該捨棄式環槽刀片20銑削時，承受銑削 力時，該捨棄式環槽刀片20承受朝下之壓力，朝下之壓力受到刀槽座11底面之支撐，該螺絲30未受到任何應力，故該捨棄式環槽刀片20之定位非常穩固。 Referring to Figure 6, the disposable ring groove insert 20 is subjected to milling when milling. When the force is applied, the disposable ring groove blade 20 receives the downward pressure, and the downward pressure is supported by the bottom surface of the knife seat 11. The screw 30 is not subjected to any stress, so the positioning of the disposable ring groove blade 20 is very stable.
請參閱第7圖所示，該捨棄式環槽刀片20之刀刃22設有斷屑 槽221，當該刀刃22銑削時，刀刃22承受朝下及朝右之分力，朝下之推力由刀槽座11之底面承受，而該朝右之推力藉由該刀槽座11之圓弧孔111承受，故該捨棄式環槽刀片20之定位非常穩固。 Referring to FIG. 7, the blade 22 of the disposable ring groove blade 20 is provided with chip breaking. The groove 221, when the cutting edge 22 is milled, the cutting edge 22 receives the downward and rightward component forces, and the downward thrust is received by the bottom surface of the sipe holder 11, and the rightward thrust is achieved by the shank seat 11 The arc hole 111 is received, so the positioning of the disposable ring groove blade 20 is very stable.
前述之實施例係為單一刀刃22，係應用於尺寸較小之環槽銑 削，請參閱第8~11圖所示，係為本發明多刀刃之實施例，該捨棄式環槽銑刀，包含一刀桿10，該刀桿10末端設有一刀盤13，該刀盤13之周緣布設有 一個以上之刀槽座11，該刀槽座11得供一捨棄式槽刀片20容置入，該刀槽座11之一隅設一呈半圓形狀之圓弧孔111，該圓弧孔111之一側設一螺孔12，該螺孔12其供螺絲頭31容置之錐形孔121係與該圓弧孔111之部位相互過切；請參閱第8、9圖所示，係為3個刀槽座11之實施例以及第10、11圖所示，係為8個刀槽座11之實施例，本發明得以應用於尺寸較大之內或外環槽銑削。 The foregoing embodiment is a single blade 22, which is applied to a ring milling with a small size. For the cutting, as shown in FIGS. 8-11, the embodiment of the multi-blade cutting blade of the present invention comprises a cutter bar 10, and a cutter head 13 is disposed at the end of the cutter bar 10, and the cutter head 13 is provided. The circumference of the cloth More than one sipe holder 11 is provided for a discarding slot blade 20, and one of the slot holders 11 is provided with a semicircular arc hole 111, one of the arc holes 111 A screw hole 12 is disposed on the side of the screw hole 12, and the tapered hole 121 for receiving the screw head 31 is cut away from the arc hole 111; for example, as shown in FIGS. The embodiment of the sipe holder 11 and the embodiment shown in Figs. 10 and 11 are eight sipe seats 11, and the present invention can be applied to a larger-sized inner or outer ring groove milling.
請參閱第12圖所示，本發明應用於內螺紋銑削之實施例，該 捨棄式環槽刀片20設有適當長度之牙刀刃221，該牙刀刃221之長度得搭配螺孔長度，該牙刀刃221之捨棄式環槽刀片20得以一次完成內螺紋之銑削，改善傳統單一牙刀刃之捨棄式刀片必須繞完整個螺紋長度才能完成銑削加工，據此得以減短加工之時間。 Referring to FIG. 12, the present invention is applied to an embodiment of internal thread milling, which The discarding ring groove cutter 20 is provided with a tooth blade 221 of a proper length. The length of the tooth blade 221 is matched with the length of the screw hole. The discarded ring groove blade 20 of the tooth blade 221 can complete the internal thread milling at one time to improve the traditional single tooth. The cutting edge of the blade must be wound around the entire thread length to complete the milling process, thereby reducing the processing time.
請參閱第13、14圖所示，係本發明刀刃22尺寸增大之實施 例，由於該刀刃22尺寸增大，且切削時將會承受較大之切削應力，故該捨棄式環槽刀片20必須增加鎖固之結構，於該捨棄式環槽刀片20適當間距之垂直方向且位於該定位栓23之一側設一讓槽243，該讓槽243之末端設一斜推面244，因此該讓槽243與推面244係位於該捨棄式環槽刀片20之垂直方向；此外該刀桿10相對於讓槽243位置設有一螺孔14，該螺孔14其供螺絲頭31容置之錐形孔141係與該圓弧孔111之部位相互重疊過切；據此該捨棄式環槽刀片20在其長度之適當位置得藉由螺絲30鎖固，使得該捨棄式環槽刀片20得以穩固地被鎖固，提升銑刀之剛性，避免銑削時產生震動現象，使銑削作業更加順暢。 Please refer to Figures 13 and 14 for the implementation of the increased size of the blade 22 of the present invention. For example, since the size of the cutting edge 22 is increased and a large cutting stress is to be applied during cutting, the discarding ring groove insert 20 must have a locking structure in the vertical direction of the appropriate spacing of the disposable ring grooved inserts 20. A slot 243 is disposed on one side of the positioning pin 23, and a slot 244 is disposed at an end of the slot 243. Therefore, the slot 243 and the pushing surface 244 are located in a vertical direction of the disc ring insert 20; In addition, the shank 10 is provided with a screw hole 14 at a position corresponding to the groove 243, and the screw hole 14 is provided with a tapered hole 141 for receiving the screw head 31 and a portion of the circular hole 111 overlapping with each other; The retractable annular grooved blade 20 is locked by a screw 30 at a proper position of the length thereof, so that the disposable annular grooved blade 20 can be firmly locked, the rigidity of the milling cutter is increased, and vibration is generated during milling, so that milling is performed. The job is smoother.
本發明之捨棄式環槽銑刀，除應用於銑削內槽孔或是內螺紋 之銑削外，應得以應用於各式之倒角作業，亦得以應用於車床之內槽、內螺紋或是各式倒角之作業。 The disposable ring groove cutter of the present invention is used for milling internal slots or internal threads In addition to milling, it should be applied to all kinds of chamfering operations, and can also be applied to the inner groove of the lathe, internal thread or various chamfering operations.
綜上所述，本發明捨棄式結構設計之環槽刀片，其體積小，不論銑削大小不同尺寸之內、外環槽，其體積大小幾近相同，僅為刀刃之尺寸變化，故改變習用捨棄式環槽刀片之設計，尺寸越大體積相對越大，而且整個鎢鋼製造之本體，尤其是非刀刃之部位，佔用捨棄式環槽刀片大部分之體積，相對浪費過多之材料於非刀刃之部位，因此造成該捨棄式環槽銑刀價格高昂及經濟效益差等缺點，故本發明完全改變習用之設計範疇，此一結構設計乃為刀具業界之首創，深具新穎性及創新性。 In summary, the ring groove insert of the discarding structure design of the present invention has a small volume, and the inner and outer ring grooves of different sizes of the milling size are almost the same in size, and only the size of the blade changes, so the change is discarded. The design of the ring groove blade is larger and the volume is relatively larger, and the whole body made of tungsten steel, especially the non-blade part, takes up most of the volume of the discarded ring groove blade, and relatively wastes too much material on the non-blade part. Therefore, the disposable ring groove milling cutter has the disadvantages of high price and poor economic efficiency. Therefore, the invention completely changes the design scope of the conventional use. This structural design is the first in the cutting tool industry, and is novel and innovative.
