이와같은 목적을 달성하기 위해 첨부된 도면에 의하여 본 발명의 일실시 구성을 알아보면, 도1은 본 발명의 전체사시도, 도 2는 본 발명의 분해조립사시도, 도 3은 본 발명의 내부구조를 나타낸 단면도로서,도시된바와 같이 테이퍼몸체(1)의 소직경 내에 엘엠베어링(12)을 내장하고 반대편의 대직경 외부끝에는 풀너트(4)를 체결한 내부 상측편에는 한쪽면이 경사면을 갖춘 파이프형상의 캠링(cam ring;14)를 테이퍼몸체(1) 외면에서 캠링고정나사(14')로 고정하고,테이퍼몸체(1)의 대직경 최상측편 내부에는 오일리스베어링(9)을 내설한후 입구를 내경멈춤링(15)으로 고정한 상기 테이퍼몸체(1)내에 위로 캡너트(3)를 나사조립식으로 수반하는 콜렛척헤드부(2a)와 캠핀설치부(2b)의 외주면과 같은 돌출높이의 초경재 캠핀(10)을 캠핀고정나사(11)로 매입설치되며,다시 단차(段差)가 소직경인 샤프트(2c)의 끝부에는 스프링장력조정너트체결나사부 (2d)와 플리축(2e)을 형성한 콜렛척샤프트(2)를 상기 테이퍼몸체(1)내에 끼워 돌출된 콜렛척샤프트(2)의 끝부에 드러스트베어링(5) 와셔(6),스프링(7),와셔(6')를 차례로 조립한후 스프링압력조정너트(8;8')로 조립한후 플리(13)를 체결하여 된것이다.In order to achieve the above object, one embodiment of the present invention will be described with reference to the accompanying drawings, FIG. 1 is an overall perspective view of the present invention, FIG. 2 is an exploded perspective view of the present invention, and FIG. 3 is an internal structure of the present invention. As shown, a pipe having an inclined surface on one side of the inner upper side in which the L bearing 12 is embedded in the small diameter of the tapered body 1 and the pull nut 4 is fastened to the large diameter outer end of the opposite side as shown in FIG. The cam ring 14 of the shape is fixed to the cam ring fixing screw 14 'on the outer surface of the tapered body 1, and the oilless bearing 9 is internally installed inside the uppermost side of the large diameter of the tapered body 1. In the tapered body (1) in which the inlet is fixed by the inner diameter stop ring (15) of the protrusion height such as the outer circumferential surface of the collet chuck head portion (2a) and the cam pin mounting portion (2b) with the cap nut (3) screwed up The cemented carbide cam pin 10 is installed with the cam pin fixing screw 11, and At the end of the shaft 2c having a small diameter step, a collet chuck shaft 2 having a spring tension adjustment nut fastening screw portion 2d and a pleat shaft 2e is fitted into the tapered body 1 to protrude. Assemble the thrust bearing (5), washer (6), spring (7) and washer (6 ') at the end of the chuck shaft (2) in turn, and then assemble with the spring pressure adjusting nut (8; 8') 13) was concluded.

이와같이 조립구성된 본 장치의 일실시 작용으로는 도 3에 도시된바와 같이, 플리(13)의 회전에 의하여 콜렛척샤프트(2)가 테이퍼몸체(1)내에서 회전하게 되면, 테이퍼몸체(1)의 샤프트(2c)와 단차(段差)로 직경이 더큰 캠핀설치부(2b)의 단차(段差)면에 돌출되게 매입고정된 초경재 캠핀(10)에 한쪽면이 경사면을 갖춘 파이프 형상의 캠링(cam ring;14)에 내접되어 샤프트(2c)방향으로 반복동작하는데 그 구간은 상기 캡핀(10)의 돌출높이만큼 반복동작하면서 콜렛척샤프트(2)가 회전하게 된다.As shown in FIG. 3, the collet chuck shaft 2 rotates in the tapered body 1 due to the rotation of the fleece 13, and thus the tapered body 1 is assembled. Pipe-shaped cam ring with one inclined surface on the cemented carbide cam pin 10, which is fixed to protrude to the step surface of the cam pin mounting portion 2b having a larger diameter with a shaft 2c of the The collet chuck shaft 2 rotates while being inscribed to the cam ring 14 and repeatedly operated in the direction of the shaft 2c while the section is repeatedly operated by the protrusion height of the cap pin 10.

상기에서 스프링압력조정너트(8;8')를 조이면 스프링(7)의 장력이 세지면서 캠핀(10)과 캠링(14)사이에 내접되는 장력이 강해지는데이의 조정은 오랜사용으로 상기 마모가 되는 경우 헐겁지 않도록 조여주는 것이다.Tightening of the spring pressure adjusting nut (8; 8 '), the tension of the spring (7) is increased while the tension in the indentation between the cam pin (10) and the cam ring (14) is strong, the wear is long-lasting If you do not loosen it will tighten.

한편,풀너트(4)는 테이퍼몸체(1)를 만능공구연삭기의 모르스 테이퍼스핀들에 조립설치할때 사용하는 너트로 사용된다.On the other hand, the pull nut (4) is used as a nut used when assembling the tapered body (1) to morse taper pins of the universal tool grinder.

이와같은 콜렛척샤프트(2)의 헤드부인 콜렛척헤드부(2a)에 일반 면취공구(도시되지 않았음)를 끼우고 캡너트(3)로 조립해 만능공구연삭기의 모르스 테이퍼스핀들에 부착하여 사용하는 본 장치는 기본적으로 X축상 일정구간을 왕복하면서 익센트릭 릴리프(eccentric rellef)의 가공여유각을 구현하는 면취공구연삭장치에 관한 것이다.A general chamfering tool (not shown) is inserted into the collet chuck head portion 2a, which is the head portion of the collet chuck shaft 2, assembled with a cap nut 3, and attached to morse taper pins of a universal tool grinder. The apparatus basically relates to a chamfering tool grinding device that implements the allowance angle of the eccentric rellef while reciprocating a certain section on the X axis.

본 발명장치에 따른 면취공구연삭장치에 의하면, 지금까지 드릴이나 커어등의 날을 연삭하는 도구로서, 고가의 CNC선반에 의해 작업을 수행하지 않아 사용자의 부담을 줄였고, 또 수동에 의한때는 작업성이 좋지 않아 제품 불량율이 높았으나 본 장치를 일반 만능공구연삭기(C-40S)의 모르스 테이퍼스핀들에 간단히 부착하여 사용할수 있으므로,별도의 특수장비를 구입하지 않아도 복잡한 탭가이드부의 연삭이나 기타 공구날끝이 부착된 각종 절삭기계용 공구들의 날끝을 용이하고 일정하게 연삭할수 있는 장치로서 매우 유용한 발명인 것이다.According to the chamfering tool grinding device according to the present invention, as a tool for grinding a blade such as a drill or a pier, it has not been carried out by expensive CNC lathes, thus reducing the burden on the user, and workability when manually Although the product defect rate was high, the device could be simply attached to morse taper pins of general multi-purpose tool grinder (C-40S). It is a very useful invention as a device that can easily and constantly grinding the blade edge of the various cutting machine tools attached.
