본 고안은 금속의 가공에 사용되는 팁(Tip : 일명, 인서트(insert)라고도한다)과 홀더의 지지구조에 관한 것이다.The present invention relates to a support structure of a tip (also called an insert) and a holder used for machining a metal.
이러한 기술분야에서 금속의 절삭을 행하는데 있어서는 공작물보다 경도(硬度)가 높은 공구 즉 팁을 홀더에 부착시켜 사용하게 된다.In the cutting of metal in this technical field, a tool having a higher hardness than a workpiece, that is, a tip, is attached to a holder.
공작물을 절삭한다는 것은 공작물에 소성변화를 주어 칩(chip)을 공작물 표면에서 분리시키는 것이기 때문에 팁이 부착된 홀더에는 공작물모우터 큰 저항 즉, 상당한 하중이 걸리는 것이므로 사용도중에 팁과 홀더간의 밀착이 이완되어 느슨해지지 않도록 하는 것이 중요한 것이다.Since cutting the workpiece gives plastic change to the workpiece to separate the chip from the surface of the workpiece, the holder with the tip is subjected to a large resistance of the workpiece motor, that is, a considerable load. It is important not to loosen.
그러므로, 이러한 기술분야에서의 선행기술은 팁을 홀더에 용접등의 방법으로 영구적으로 부착하는 방법이나 제1도및 제2도와 같이 방법등이 알려져 있었다.Therefore, the prior art in this technical field is known how to permanently attach the tip to the holder by welding or the like, or the method as shown in FIGS. 1 and 2.
즉, 제1도와같이 L자형의 괘지구(7)가 팁(8)의 괘지공일측에 걸리도록한뒤 별도의 나사공에 나합되는 볼트(9)에 걸리지게 하므로서 체결시에 볼트(9)의 괘지턱으로 L자형의 괘지구(7)가 팁괘지공 후단을 밀어주어 고정토록하는 캠록(Cam Lock)방식과, 제2도와같이 크램프(10)전단이 팁(8')의 후단상면을 압압토록함과 동시에 팁저면에는 보조나사로 고정되어 있는 받침편(11)이 팁을 상부로 받쳐주는 구조인 크램프 온 타입(Clamp on Type)이 있다.That is, as shown in FIG. 1, the L-shaped ruled seat 7 is caught on the ruled hole side of the tip 8 and then caught by a bolt 9 that is screwed into a separate screw hole. The cam lock method in which the L-shaped ruler (7) pushes the rear end of the tip ruler hole to fix the ruler, and the front end of the clamp (10) as shown in FIG. Simultaneously with pressing, there is a clamp on type (Clamp on Type), which is a structure in which the support piece 11 fixed with an auxiliary screw supports the tip to the top.
그러나, 이러한 선행기술에 있어서는 팁을 홀더에 용접하여 영구적으로 부착시키는 방법은 팁과 홀더간의 완벽한 밀착조건을 부여할 수는 있으나, 사용에 의해 마모된 팁을 교환하히위해서는 팁이 용접된 부위를 가열하면 팁을 제거한 후 다시 용접하여 교환하여야하는 번거로움이 있는 것이었다. 또한 캠록방식및 크램프 온타임은 그 형상이 복잡하여 제작가공이 어렵고 이로인한 조립작업의 복잡성은 물론 소요 경비가 많이들며, 사용도중에는 견고하게 고정되었던 부분이 이완되고 헐거워지므로서 공작물 가공의 정도가 저하되고 심지어는 팁이 파쇄되는 등의 불합리한 결점이 있었다.However, in this prior art, the method of permanently attaching the tip to the holder by welding may impart perfect contact between the tip and the holder. However, in order to replace the worn tip by use, the tip is heated. This was a hassle to remove the tip and weld again to replace. In addition, the camlock method and clamp on-time are complicated in shape, which makes the fabrication process difficult, thereby increasing the complexity of assembling work and the cost, and the degree of workpiece machining is reduced due to the loosening and loosening of the fixed parts during use. There was an irrational flaw, even if the tip was broken.
특히, 홀더의 재치면에 불순물이 게재되어 팁이 고정된 경우에는 팁과 홀더간에 견고하게 고정되었던 부분이 더욱 쉽게 이완되고 헐거워지므로서 공작물가공 정도가 저하되고, 가공시 이로인해 팁의 떨림이 발생되어 팁이 파쇄될 염려가 많은 것이었다.Particularly, when impurities are placed on the mounting surface of the holder and the tip is fixed, the precision of the workpiece is reduced by loosening and loosening the parts firmly fixed between the tip and the holder more easily. There was a lot of fear that the tip would break.
본 고안의 목적은 상기와같은 제반폐단및 결점을 모두 제거할 수 있도록 지지불재와 볼트에 서로 대응되게 구면요홈과 구면돌조를 부여함에 의해 그 구성이 간단하게되고 이로인해 제작상의 편리한 효과를 갖는 금속가공용 팁과 홀더의 지지구조를 제공함에 있다.The object of the present invention is to simplify the construction by providing spherical grooves and spherical protrusions corresponding to each other to the support member and the bolt so as to eliminate all the closing and defects as described above, thereby having a convenient effect on the production The present invention provides a support structure for a metal working tip and a holder.
또한, 본 고안의 다른목적은 홀더의 재치면에 불순물이 삽입되어 팁이 고정되어도 팁의 상단면을 균일하게 가압하여 밀착고정되므로 이완되어 헐거워지지않으며, 이로인해 공작물의 가공정도가 향상됨은 물론 팁이 파쇄될 염려가 없는 등의 그 기능이 향상된 금속가공용 팁과 홀더간의 지지구조를 제공함에 있다.In addition, another object of the present invention is that even if the tip is fixed to the mounting surface of the holder fixed evenly by pressing the top surface of the tip evenly fixed, so that it is not loosened loose, thereby improving the processing accuracy of the workpiece as well as the tip It is to provide a support structure between the holder and the tip for metal working improved such that there is no fear of fracture.
이하에서 본 고안을 좀더 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.
제3도및 제4도는 본 고안의 일실시예를 보여주고 있는 것인데, 여기서는 홀더(1)의 전단재치면(1l)에 통공(2l)(31)이 천설된 팁(2)과 지지부재(3)가 재치되어 보울트(4)로 고정되어진다. 상기 지지부재(3)의 통공(31)상부에는 구면요홈(32)을 요설하고 사어기 보울트(4)의 헤드부저면에는 구면돌조(41)를 형성시킨 것이다.3 and 4 show an embodiment of the present invention, in which a tip 2 and a support member (2) and 31 having a through hole 2l and 31 are installed in the shear mounting surface 1l of the holder 1. 3) is placed and fixed to the bolt 4. A spherical groove 32 is formed in the upper portion of the through hole 31 of the support member 3, and a spherical protrusion 41 is formed on the bottom surface of the head of the frying bolt 4.
상기와같은 구성의 본 고안은 제3도에서와 같이 홀더(1)의 재치면(11)에 팁(2)을 재치하고 팁(2)의 상단면에는 구면요홈(32)이 상부측으로 향하도록 지지부재(3)를 재치시켜 지지부재(3)의 구면요홈(32)에 보울트(4)의 구면돌조(4l)가 삽입되게 홀더(1)의 나사공에 체결 고정된다.According to the present invention, the tip 2 is placed on the mounting surface 11 of the holder 1 and the spherical groove 32 is directed toward the upper side of the tip 2, as shown in FIG. The support member 3 is placed and fastened to the screw hole of the holder 1 so that the spherical protrusion 4l of the bolt 4 is inserted into the spherical recess 32 of the support member 3.
또, 제4도에서와같이 홀더(1)의 재치면(11)에 불순물이 게재된 상태에서 팁(2)과 지지부재(3)가 일측으로 경사되게 지지되어 보울트(4)로 고정되는 경우에도 지지부재(3)의 구면요홈(32)전면에 보울트(4)의 구면돌조(41)가 균일하게 가압하므로 팁이 경사진 상태에서 견고하게 고정된다.In addition, when the tip 2 and the support member 3 are inclined to one side and fixed with the bolt 4 in the state where impurities are placed on the mounting surface 11 of the holder 1 as shown in FIG. Since the spherical protrusion 41 of the bolt 4 is uniformly pressed against the front surface of the spherical recess 32 of the support member 3, the tip is firmly fixed in the inclined state.
제5도는 본 고안의 다른 실시예를 도시한 것으로서, 이는 홀더(1)의 재치면(11)에 통공이 천설되지않은 팁(2')과 구면요홈(33)이 요설된 지지부재(3)를 얹어놓고, 보울트(6)에 의해 가압되어지는 크램프(5)가 팁(2')를 견고하게 고정토록 구성하되 지지부재(3')의 구면요홈(33)에 크램프(5) 일측의 구면돌조(51)이 상이되어지도록 한다.5 is a view showing another embodiment of the present invention, which is a support member 3 in which a tip 2 'and a spherical recess 33 in which a hole is not laid in the mounting surface 11 of the holder 1 are provided. The top of the clamp (5) on one side of the clamp (5) in the spherical groove (33) of the support member (3 '), and the clamp (5) pressurized by the bolt (6) is configured to be firmly fixed. The protrusions 51 are different.
상기와 같이 구성된 본 고안은 팁과 홀더의 재치면사이에 불순물이 삽입되어있는 상태에서 팁이 부착고정되어도 보울트(4)및 크램프(6)의 구면돌조(4l)(51)가 지지부재(3)(3')의 구면요홈(32)(33)에 구면으로 밀착되어 있으므로 팁의 상단면을 균일하게 가압되어 팁이 밀착고정되는 것이다.According to the present invention configured as described above, the spherical protrusions 4l and 51 of the bolt 4 and the clamp 6 are supported by the support member 3 even when the tip is fixed while the impurities are inserted between the tip and the mounting surface of the holder. Since the spherical grooves 32 and 33 of the 3 'are closely adhered to the spherical surface, the upper end of the tip is uniformly pressed and the tip is tightly fixed.
그러므로, 홀더에 팁이 부착된 지지부위가 극히 간단한 구조로 견고하게 밀착고정시킬수 있으므로 제작상의 편리한 효과가 있고 사용도중에 지지부위가 쉽게 이완되어 헐거워 지지않으며, 이로인해 공작물의 가공정도가 향상됨은 물론 팁이 파쇄될 염려가 없는 등의 그 기능이 양호하게 개선되는 유익한 특징이 있는 것이다.Therefore, the support part with the tip attached to the holder can be fixed tightly in an extremely simple structure, which is convenient in manufacturing, and the support part is easily relaxed during use, so that it does not loosen. There is an advantageous feature that the function thereof is improved, such that there is no fear of crushing.
