본 고안은 프로파일 연마기에 관한 것으로서, 보다 상세하게는 가공이 용이하고 가공정도를 향상시킬 수 있는 프로파일 연마기용 지그에 관한 것이다.The present invention relates to a profile polishing machine, and more particularly, to a profile polishing machine jig that can be easily processed and improves the degree of processing.

프로 파일 연마기는 화면상에 나타나는 가공상태를 보면서 가공토록 되어 있으므로, 일반적인 연마기보다 정밀한 가공을 할 수 있다.The profile grinder is designed to be processed while watching the machining conditions appearing on the screen, so that the machining can be performed more precisely than a general grinder.

따라서 프로 파일 연마기는, 일반적인 연마기가 외주면을 환삭 가공 하는데 비해서 등분 형성되는 형상으로 가공을 할 때 주로 사용 되고 있다.Therefore, profile grinders are mainly used when the general grinder is processed into a shape that is equally formed as compared to the circular machining of the outer peripheral surface.

제3도는 3등분 위치에 홈이 형성되는 구멍을 뚫기 위한 펀치의 일예를 나타낸 도면으로서, 펀치(S)는 펀칭부(S1)과 자루부(S2)로 되어 있다.3 is a view showing an example of a punch for drilling holes in which grooves are formed in three equal positions, wherein punch S is formed of punching portion S1 and bag portion S2.

펀칭부(S1)은 제3b도에 도시한 바와 같이 3등분 지점에 돌출부(A), (B), (C)가 형성되어 있으며, 이들 사이는 오목부(D), (E), (F)가 형성되어 있다.As shown in Fig. 3b, the punching portions S1 are formed with protrusions A, B, and C, and the recesses D, E, and F between them. ) Is formed.

이와같이 형성되는 펀치의 펀칭부(P1)을 가공하기 위해서는 먼저 가공소재를 3등분 하여야 되는데, 종래에는 조합 각자나 베벨분도기 등을 사용하여 등분을 하였다.In order to process the punching portion P1 of the punch formed as described above, first, the processed material must be divided into three parts. Conventionally, each of the combinations or a bevel protractor was used to divide the materials.

그러나 이와 같이 등분된 가공소재를 프로파일 연마가공하기 위해서는 바이스에 고정시켜야 하는데, 3등분된 각각의 지점을 바이스의 양조오 사이의 중심에 정확히 고정시키는 것이 거의 불가능하여 정확한 3등분이 어렵다.However, in order to profile-process the equally divided workpiece, it is necessary to fix it in a vise, and it is almost impossible to accurately fix each point divided into three parts at the center between brew brews of the vise.

그리고, 가공소재를 바이스에 고정시킬때 수평도를 맞추기 위해서는 다이얼 게이지 등으로 수평상태를 측정하여야 하므로 작업이 번거롭고 작업시간도 많이 소요되는 문제점이 있다.In addition, since the horizontal state is to be measured by a dial gauge in order to adjust the horizontality when fixing the workpiece to the vise, the work is cumbersome and takes a lot of time.

본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 가공이 용이하고 가공정도를 향상시킬 수 있는 프로파일 연마기용 지그를 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 jig for profile polishing machine that can be easily processed and improve the degree of processing.

상기한 바와 같은 목적을 달성하기 위하여 본 고안은, 몸체의 길이 방향으로 구멍이 관통 형성되고. 이 구멍의 외측 양단으로부터 소정의 길이로 받침대가 연장 형성되어 이들 받침대 사이에 개구부가 형성되는 프로파일 연마기용 지그를 제공 한다.In order to achieve the object as described above, the present invention, the hole is formed in the longitudinal direction of the body. A pedestal extends to a predetermined length from the outer ends of the holes to provide a jig for a profile grinder in which an opening is formed between the pedestals.

이한 본 고안의 바람직한 실시예를 첨부한 도면에 따라 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 펀치 지그 사시도로서, 부호(1)은 몸체를 나타낸다.1 is a perspective view of a punch jig according to the present invention, and reference numeral 1 denotes a body.

몸체(1)에는 길이 방향으로 반원상의 구멍(2)가 관통 형성되어 있으며, 이 구멍(2)의 외측 양단에는 받침대(3), (3')가 중앙으로 연장 형성되어 있다.A semicircular hole 2 is formed in the body 1 in the longitudinal direction, and pedestals 3 and 3 'are formed at both ends of the outside of the hole 2 in the center thereof.

상기한 받침대(3), (3')사이에는 간격이 형성되어 개구부(4)가 형성되어 있다.A gap is formed between the pedestals 3 and 3 'so that the opening 4 is formed.

본고안의 실시예에서는 구멍(2)를 반원 형상으로 하고 있으나, 이에 한정되는 것은 아니고, 일정한 공간을 확보할 수 있으면 어떠한 형상도 무방하다.In the embodiment of the present invention, the hole 2 has a semi-circular shape, but the shape of the hole 2 is not limited thereto.

몸체(1)에는 상기한 구멍(2)와 직교 방향으로 나사 구멍이 뚫려져 고정나사(5)를 체결할 수 있게 되어 있다.In the body 1, a screw hole is drilled in a direction orthogonal to the above-mentioned hole 2, so that the fixing screw 5 can be fastened.

받침대(3), (3')의 마주 대향 하는 끝단은 원호면(6), (6')로 형성하는 것이 더욱 바람직하다.It is more preferable that the opposite ends of the pedestals 3 and 3 'are formed of arcuate surfaces 6 and 6'.

이와같이 구성되는 본 고안의 펀치 지그는 제2도에 도시한 바와 같이, 몸체(1)에 뚫려진 구멍(2A)에 펀치 가공소재(P)를 삽입시키고, 고정나사(5)로 고정시킨다.As shown in FIG. 2, the punch jig according to the present invention configured as described above inserts the punched workpiece P into the hole 2A drilled in the body 1, and is fixed by the fixing screw 5. As shown in FIG.

그러면 가공소재(P)의 외주면 일부가 받침대(3), (3')의 원호면(6), (6')에 밀착되면서 받침대(3), (3')사이로 노출된다.Then, a part of the outer circumferential surface of the workpiece P is exposed between the pedestals 3 and 3 'while being closely attached to the circular arc surfaces 6 and 6' of the pedestals 3 and 3 '.

이때 원호면(6), (6')와 고정나사(5)의 끝단부가 정삼각형을 이루게 되는데 이러한 상태에서 바이스(V)에 물려놓고 연삭기(G)로 제1오목부(D)를 가공한 다음, 고정나사(5)를 풀고 가공소재(P)를 돌려서 원호면(6)에 밀착되었던 가공소재(P)의 외주면이 원호면(6')의 위치에 오게하고, 고정나사(5)의 끝단부가 접촉 되었던 외주면을 원호면(6)의 위치에 오게한후 고정나사(5)를 다시 고정 시킨다.At this time, the end portions of the circular arc surfaces 6, 6 'and the fixing screw 5 form an equilateral triangle. In this state, the first recessed part D is processed by a grinding machine G after being bitten by a vise V. Loosen the set screw (5) and turn the work piece (P) so that the outer circumferential surface of the work piece (P), which has been in close contact with the round face (6), is at the position of the round face (6 '), and the end of the set screw (5) Place the outer circumferential surface that was in contact with the arc at the position of the arc surface 6, and then fix the fixing screw 5 again.

이러한 상태에서 연삭기(G)로 제2오목부(E)를 가공하고, 다시 상기한 방식과 동일하게 가공소재(P)를 돌려 제3오목부(F)를 가공하면 제3도에 도시한 바와 같은 펀치가 형성된다.In this state, the second concave portion E is processed by the grinding machine G, and the third concave portion F is processed by turning the workpiece P again in the same manner as described above. The same punch is formed.

상기한 바와 같이 본 고안의 펀치 지그는 펀치 가공 소재를 돌려 가면서 각각의 밀착점을 옮기면 정확한 3등분이 되어 가공 되므로 종래 3등분 작업을 하지 않고도 정확하게 가공할 수 있고, 몸체의 원호면에 길이방향으로 가공 소재가 위치 되므로 수평을 맞출 필요가 없어 작업이 용이하다.As described above, the punch jig of the present invention is processed to be precisely divided into three parts by moving each contact point while rotating the punch material, and thus can be accurately processed without the conventional three-part work, and in the longitudinal direction on the circular arc surface of the body. Since the workpiece is positioned, there is no need for leveling, which facilitates work.
