본 고안은 선반을 이용한 내면 브로우칭용 홀더에 관한 것으로서, 보다 상세하게는 브로우칭 작업을 용이하게 할 수 있도록한 브로우칭용 홀더에 관한 것이다.The present invention relates to a holder for internal broaching using a shelf, and more particularly, to a holder for broaching to facilitate a broaching operation.
브로우칭 작업은 브로우치라고 하는 다수의 절삭인선을 갖는 공구를 공작물내로 통과시켜 공작물을 절삭시킴으로서, 브로우치의 단면형상을 공작물에 옮기는 작업이다.The broaching operation is to transfer a cross-sectional shape of the brooch to the workpiece by cutting the workpiece by passing a tool having a plurality of cutting edges, called a broach, into the workpiece.
브로우치는 작업의 종류에 따라 내면 브로우치와 표면 브로우치로 대별되어 있으며, 브로우치의 운동방향에 따라 인발 브로우치와 압출 브로우치, 그리고 특수한 회전 브로우치로 분류된다.According to the type of work, the broach is divided into inner broach and surface broach, and according to the movement direction of the broach, it is classified into drawing broach, extrusion broach and special rotating broach.
이러한 브로우칭 작업은 그 작업의 특수성으로 인하여 브로우치 머신에서만 행해지고 있다.This broaching operation is performed only on a broaching machine due to its specificity.
이와같이 브로우칭 작업은 그 작업이 한정된 전용기계에서만 행하여지기 때문에 소정의 형상을 가공하기 위한 작업들 예컨대 환삭, 절삭 등의 작업과 연관성이 없어 생산성이 저하되는 한 요인이 되고 있다.Since the broaching operation is performed only on a limited dedicated machine, the broaching operation is not associated with operations for machining a predetermined shape, for example, turning, cutting, etc., which is one factor of lowering productivity.
본 고안은 상기한 바와같은 종래 기술의 문제점을 해소하기 위하여 안출된 것으로서, 본 고안의 목적은 선반에서도 작업을 가능케 하는 내면 브로우칭용 홀더를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to provide a holder for the inner broaching to enable work on the shelf.
이를 실현하기 위하여 본 고안은 브로우치가 관통하는 안내공이 뚫려진 플랭크부와 선반의 공구대에 고정되는 생크부가 일체로 형성된 내면 브로우칭용 홀더를 제공한다.In order to realize this, the present invention provides a holder for inner broaching, in which a flank portion through which a broach penetrates and a shank portion fixed to a tool post of a lathe are integrally formed.
이하 본 고안의 바람직한 실시예를 첨부한 도면에 따라서 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
제1도는 본 고안의 홀더가 장착된 상태를 나타내는 도면으로서, 홀더(1)는 공구대(2)에 장착되는 생크부(6)와 브로우치(3)가 끼워지는 안내공(4)이 뚫려진 플랭크부(5)가 일체로 형성되어 있다.1 is a view showing a state in which the holder of the present invention is mounted, the holder 1 is a guide hole (4) to be fitted with the shank portion 6 and the brooch (3) to be mounted on the tool post (2) The flank 5 is integrally formed.
제2도는 본 고안의 홀더에 끼워져 사용되는 브로우치(3)의 구성을 나타내는 도면으로서, 안내부(3a)와 절삭인선부(3b), 그리고 연장부(3c)로 이루어져 있다.2 is a view showing the configuration of the brooch 3 to be used in the holder of the present invention, and is composed of a guide portion 3a, a cutting edge portion 3b, and an extension portion 3c.
제3도는 홀더(1)와 브로우치(3)를 사용하여 선반에서 브로우칭 가공을 하는 상태를 나타내는 도면으로서, 선반척(T)에 스텝센터(7)가 물려지고, 이 스텝센터(7)와 심압대(8) 사이에 브로우치(3)가 고정되어 있다.3 is a view showing a state of broaching on a lathe using the holder 1 and the brooch 3, wherein the step center 7 is bitten by the lathe chuck T, and the step center 7 and The brooch 3 is fixed between the tail stocks 8.
이러한 상태에서 브로우칭 가공을 행하는 경우에는 홀더(1)를 공구대(2)에 장착시키고, 다이얼 인디케이터 등으로 직각도를 맞춘다.In the case of carrying out broaching in such a state, the holder 1 is attached to the tool rest 2, and a right angle is adjusted with a dial indicator or the like.
그다음 공작물(12)을 브로우치(3)의 안내부(3a)에 삽입시킨 상태에서 이 안내부(3a)와 일체로된 연장부(3c)를 홀더(1)의 안내공(4)으로 관통시킨다.Then, the workpiece 12 is inserted into the guide portion 3a of the brooch 3, and the extension portion 3c integrated with the guide portion 3a is passed through the guide hole 4 of the holder 1. .
이어서 공구대(2)를 이송시켜 브로우치(3)의 센터와 심압대(8)의 센터를 일치시킨 다음, 심압대(8)를 이송시켜 브로우치(3)를 스텝센터(7)와의 사이에 고정한다.The tool post 2 is then transferred to align the center of the broach 3 with the center of the tailstock 8, and then the tailstock 8 is transported to fix the brooch 3 between the step center 7. do.
이러한 상태에서 선반의 에이프론 핸들(9)를 반시계방향으로 돌리게 되면 왕복대(10)가 좌측으로 이송됨에 따라 공구대(2)가 같이 이송된다.When the apron handle 9 of the lathe is turned counterclockwise in this state, the tool post 2 is conveyed together as the carriage 10 is moved to the left.
그러면 홀더(1)가 공작물(12)을 좌측으로 미는 결과가 되어 브로우치(3)의 절삭인선부(3b)를 통과하면서 브로우칭 가공이 행하여 진다.As a result, the holder 1 pushes the work piece 12 to the left side, and broaching is performed while passing through the cutting edge portion 3b of the brooch 3.
즉 브로우치(3)의 안내부(3a)에 위치된 공작물(12)이 절삭인선부(3b)를 통과하면서 절삭가공되는데, 이 절삭인선부(3b)는 점차 확대되는 테이퍼를 이루고 있으므로 조금씩 절삭가공되고, 최종적으로는 절삭인선부(3b)가 평행을 이루는 곳을 통과하면서 공작물이 12a의 위치로 되었을 때 작업완료된다.That is, the workpiece 12 located in the guide portion 3a of the brooch 3 is cut while passing through the cutting edge portion 3b. The cutting edge portion 3b forms a taper which gradually enlarges, so the cutting portion is gradually cut. Finally, the work is completed when the workpiece is in the position of 12a while passing through the cutting edge portion 3b in parallel.
이러한 작업이 진행되는 동안 본 고안의 홀더는 브로우치가 수평이동이 되도록 하기 때문에 제4도에 도시한 바와같은 브로우칭 가공상태를 보다 양호하게 할뿐아니라 선반에서 작업을 가능케 한다.While this operation is in progress, the holder of the present invention allows the broach to be horizontally moved, thereby making it possible to work on the lathe as well as to improve the broaching state as shown in FIG.
