본 고안은 절삭기능을 향상시킨 브로치에 관한 것으로, 특히 브로치의 강성을 보강하여 수명을 연장하고, 절삭력을 증대시켜 가공 제품의 품질을 향상시킬 수 있도록 한 절삭기능을 향상시킨 브로치(BROACH)에 관한 것이다.The present invention relates to a broach with improved cutting function, and more particularly, to a broach with improved cutting function to enhance the broach's stiffness to extend its service life and increase cutting force to improve the quality of a processed product. will be.
제1도와 제2도에 나타낸 바와 같이, 종래에는 브로치 몸체(10)의 상면에 상사형의 치형을 순차적으로 형성시킨 치형부(11)를 형성하고, 상기 치형부(11)에 한 개의 치형을 제거한 체결부(12)를 형성시키되, 상기 체결부(12)에 제품 가공장비와 브로치 몸체(10)를 체결시키는 체결공(13)을 형성하여 구성하였다.As shown in FIG. 1 and FIG. 2, in the related art, a tooth 11 is formed by sequentially forming a similar tooth on the upper surface of the broach body 10, and one tooth is removed from the tooth 11. FIG. The fastening part 12 was formed, but the fastening part 12 was formed by forming a fastening hole 13 for fastening the product processing equipment and the brooch body 10.
이러한 종래의 브로치는 자동차용 조향 장치의 일부인 틸트 칼럼용 고정기어와 가동기어를 절삭 가공하기 위하여 브로치 몸체(10)의 체결부(12)에 형성된 체결공(13)을 통하여 브로치 연삭기(Broach Sharpness) 등에 체결시켜 공작물을 절삭 가공 하였다.The conventional broach is broach sharpness through a fastening hole 13 formed in the fastening portion 12 of the broach body 10 for cutting the tilt column fixed gear and the movable gear which are part of the steering device for automobiles. The workpiece was cut by fastening to the back.
그러나 이러한 종래의 브로치는 브로치 몸체(10)의 체결부(12)에 형성된 체결공(13)에는 치형이 형성되어 있지 않아 절삭 가공시 절삭의 맥이 끊어질 뿐 아니라 이로 인하여 제품의 품질이 떨어지는 결점이 있었다.However, such a conventional broach is not formed in the fastening hole 13 formed in the fastening portion 12 of the brooch body 10, so that not only the cutting mace is cut during cutting, but also the defect of poor product quality. There was this.
또한 체결부(12)에 치형이 형성되지 않아 브로치의 체결공(13)부분 강성이 약화되어 쉽게 부러지는 등의 손상으로 브로치의 수명을 단축시키고, 이로 인하여 브로치의 소모량이 증가되는 문제점이 있었다.In addition, since the teeth are not formed in the fastening part 12, the rigidity of the fastening hole 13 part of the broach is weakened, and thus the life of the broach is shortened due to damage such as being easily broken, thereby increasing the consumption of the broach.
따라서 본 고안은 상기한 문제점을 해소하기 위하여 안출한 것으로, 그 목적은첫째; 브로치의 절삭력을 증대시켜 절삭 가공한 제품의 품질을 향상시키고, 둘째; 강성을 보강하여 브로치의 수명을 연장시키므로 브로치의 소모를 최소로 줄일 수 있도록 하는 절삭 기능을 향상시킨 브로치를 제공하는데 있다.Therefore, the present invention has been devised to solve the above problems, the purpose is first; Increase the cutting force of the brooch to improve the quality of the cut product; It is to provide a broach with an improved cutting function to reduce the consumption of the broach by minimizing the broach consumption by extending the life of the brooch by reinforcing the rigidity.
위와 같은 목적을 달성하기 위하여 본 고안은 브로치 몸체의 상면에 상사형이 치형을 순차적으로 형성시킨 치형부를 형성시키되, 상기 치형부의 소정위치에 체결부를 형성하고, 체결부에 가공장비와 브로치를 체결시키는 체결공을 형성하며, 체결부의 체결공에 보조 치형을 형성시켜 구성함을 그 기술적 구성상에 기본 특징으로 한다.In order to achieve the above object, the present invention is formed on the upper surface of the broach body to form a tooth to form a tooth in sequence, the fastening to form a fastening portion at a predetermined position of the tooth, the fastening to fasten the processing equipment and brooch Forming a ball, and forming the auxiliary tooth in the fastening hole of the fastening portion is characterized in that the basic configuration on the technical configuration.
위와 같이 구성된 본 고안의 실시예를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings an embodiment of the present invention configured as described above are as follows.
제3도와 제4도에 나타낸 바와 같이, 자동차용 조향 장치의 일부인 틸트 칼럼용 고정기어와 가동기어를 절삭 가공하기 위한 브로치에 관한 것으로, 본 고안은 브로치 몸체(10)의 상면에 상사형의 치형을 순차적으로 배열시킨 치형부(11)를 형성하되, 상기 치형부(11)의 소정위치에 체결부(12)를 형성하고, 체결부(12)에 브로치 연삭기능의 절삭 가공장비와 브로치를 체결시키는 체결공(13)을 형성하며, 상기 체결부(12)의 체결공(13) 전후면에 상기 치형부(11)의 치형과 등간격으로 형성시킨 보조치형(14)을 형성시켜 구성한다.As shown in FIG. 3 and FIG. 4, the present invention relates to a broach for cutting a tilt column fixed gear and a movable gear which are part of a steering device for automobiles. To form the teeth 11 arranged in sequence, to form a fastening portion 12 at a predetermined position of the teeth 11, and to fasten the broach grinding function and the broach grinding equipment to the fastening portion 12 The fastening hole 13 is formed, and the auxiliary tooth 14 formed at equal intervals with the teeth of the tooth 11 is formed on the front and rear surfaces of the fastening hole 13 of the fastening part 12.
이러한 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention as follows.
브로치 몸체(10)의 체결부(12)에 보조치형(14)을 치형부(11)의 치형과 등간격으로 형성시키므로 강성이 보강될 뿐 아니라 절삭 가공시 절삭력을 증대시켜 제품의 품질을 향상시키고, 브로치의 손상을 억제시킨다.Since the auxiliary tooth 14 is formed at the fastening portion 12 of the brooch body 10 at equal intervals with the teeth of the tooth 11, not only the rigidity is reinforced but also the cutting force is increased during cutting to improve the product quality. , Reduce damage to brooches.
이상에서 살펴본 바와 같이, 본 고안은 간단한 구조로 브로치의 절삭력을 증대시켜 절삭 가공한 제품의 품질을 향상시키고, 강성을 보강하여 브로치의 수명을 연장시키므로 브로치의 소모를 최소로 줄일 수 있는 것이다.As described above, the present invention is to increase the cutting force of the brooch with a simple structure to improve the quality of the cut product, and to enhance the rigidity to extend the life of the brooch to reduce the consumption of the brooch to a minimum.
