When the forged material 3 is made by forging, the forged material 3 must be processed into desired dimensions and shapes. At this time, in order to process the forged material 3, it is necessary to fix the forged material 3 to the jig plate 5. The forged material 3 fixes part A of FIG. 7 to the jig plate 5 with a fixing bolt or the like. When the forging material 3 is made by forging the block 1, the lower surface of part A is often inclined rather than parallel to the jig plate 5 as shown in FIG. In this case, the forged material 3 cannot be fixed to the jig plate 5.

그래서 종래의 경우 도 8에 도시된 바와 같이 단조소재(3)의 하부를 지그판(5)과 평행하도록 면삭가공을 한 후 지그판(5)에 고정하였다.So, in the conventional case, as shown in FIG. 8, the lower part of the forged material 3 was chamfered to be parallel to the jig plate 5, and then fixed to the jig plate 5.

따라서 종래의 경우 단조한 단조소재(3)를 지그판(5)에 바로 고정시키지 못하고 지그판(5)에 고정시키기 위하여 그 하부면을 별도로 가공해야 한다는 문제점이 있었다.Therefore, in the prior art, there was a problem that the forged material 3 could not be directly fixed to the jig plate 5, and the lower surface had to be separately processed in order to fix it to the jig plate 5.

도 1 내지 도 5를 참조하여 본 발명에 따른 단조소재 고정 볼트장치의 일 실시예를 설명한다.Referring to Figures 1 to 5 will be described an embodiment of the forged material fixing bolt device according to the present invention.

본 발명에 따른 단조소재 고정 볼트장치(x)는 잭볼트(10)와, 구면와셔(20)와, 체결볼트(30) 및 너트(40)를 포함한다.The forged material fixing bolt device (x) according to the present invention includes a jack bolt 10, a spherical washer 20, a fastening bolt 30 and a nut 40.

잭볼트(10)는 잭볼트머리부(11)와, 잭볼트나사부(13)를 구비한다. 잭볼트머리부(11)는 상부면에 구면홈(12)이 형성된다. 잭볼트나사부(13)는 지그판(51)에 형성된 볼트홈에 나사결합하도록 잭볼트머리부(11)의 하면에 결합된다. 그리고 잭볼트(10)는 잭볼트머리부(11)의 구면홈(12)에서 잭볼트나사부(13)를 항하여 나사홈(15)이 형성된다. 나사홈(15)에는 체결볼트(30)가 체결된다.The jack bolt 10 includes a jack bolt head portion 11 and a jack bolt screw portion 13. The jack bolt head 11 has a spherical groove 12 formed on the upper surface. The jack bolt screw part 13 is coupled to the lower surface of the jack bolt head part 11 so as to screw into the bolt groove formed in the jig plate 51. In addition, in the jack bolt 10, a screw groove 15 is formed from the spherical groove 12 of the jack bolt head 11 toward the jack bolt screw portion 13. A fastening bolt 30 is fastened to the threaded groove 15 .

구면와셔(20)는 잭볼트머리부(11)의 구면홈(12)에 안착될 수 있도록 하부면(21)이 구면홈(12)에 삽입될 수 있도록 구면으로 형성되고, 상부면(23)은 구면홈(12)에서 돌출되어 단조소재(53)를 지지할 수 있는 평면으로 형성된다. 그리고 체결볼트(30)가 관통하여 삽입될 수 있도록 관통공(25)이 형성된다. 이때 관통공(25)은 체결볼트(10)의 잭볼트나사부(13) 보다 직경이 더 크게 형성된다. 구면와셔(20)의 하부면(21)이 구면으로 형성되므로 구면와셔(20)는 구면홈(12)에 삽입되어 좌우전후로 회전할 수 있는 자유도를 가진다. 그래서 구면와셔(20)는 잭볼트(10)의 구면홈(12)에 삽입되면 그 상부면(23)을 구면홈(12)에서 임의의 각도로 기울일 수 있다. 이때 구면와셔(20)의 관통공(25)은 구면와셔(20)가 임의의 각도로 기울어지더라도 체결볼트(30)가 나사홈(15)에 체결되기 위하여 삽입될 때 관통공(25)을 관통할 수 있도록 그 직경이 크게 형성되어야 한다.The spherical washer 20 is formed in a spherical shape so that the lower surface 21 can be inserted into the spherical groove 12 so that it can be seated in the spherical groove 12 of the jack bolt head 11, and the upper surface 23 Is protruded from the spherical groove 12 and is formed as a plane capable of supporting the forged material 53. A through hole 25 is formed so that the fastening bolt 30 can be inserted therethrough. At this time, the through hole 25 is formed to have a larger diameter than the jack bolt screw portion 13 of the fastening bolt 10. Since the lower surface 21 of the spherical washer 20 is formed in a spherical shape, the spherical washer 20 is inserted into the spherical groove 12 and has a degree of freedom to rotate left and right and back and forth. So, when the spherical washer 20 is inserted into the spherical groove 12 of the jack bolt 10, its upper surface 23 can be tilted at an arbitrary angle in the spherical groove 12. At this time, the through hole 25 of the spherical washer 20 forms the through hole 25 when the fastening bolt 30 is inserted to be fastened to the screw groove 15 even if the spherical washer 20 is inclined at an arbitrary angle. Its diameter must be formed large so that it can penetrate.

체결볼트(30)는 체결볼트나사부(31)와 체결볼트머리부(33)를 구비한다. 체결볼트나사부(31)는 단조소재(53)와 관통공(25)을 관통하여 나사홈(15)에 나사체결된다. 체결볼트머리부(33)는 체결볼트나사부(31)가 나사홈(15)에 삽입되면 단조소재(53)를 가압하여 고정하도록 체결볼트나사부(31)에 결합된다.The fastening bolt 30 includes a fastening bolt threaded portion 31 and a fastening bolt head 33 . The fastening bolt screw portion 31 penetrates the forged material 53 and the through hole 25 and is screwed into the screw groove 15. When the fastening bolt head 33 is inserted into the screw groove 15, the fastening bolt head 33 is coupled to the fastening bolt screw 31 to pressurize and fix the forged material 53.

너트(40)는 지그판(51)의 상면에 지지되어 잭볼트(10)와 결합한다. 체결볼트(30)를 잭볼트(10)에 체결하면 잭볼트(10)가 체결볼트(30)와 함께 회전하여 지그판(51)에 삽입될 수 있다. 이 경우 잭볼트(10)의 높낮이가 달라져서 단조소재(53)를 지지할 수 없게 되므로 이를 방지하기 위하여 체결볼트(30)를 잭볼트(10)에 체결하기 전에 잭볼트(10)의 높낮이를 맞춘후 너트(40)가 지그판(51)의 상단에 지지되도록 잭볼트(10)에 체결한다. 그리고 체결볼트(30)를 잭볼트(10)에 체결하면 잭볼트(10)는 고정된채 체결볼트(30)와 잭볼트(10)가 체결될 수 있다.The nut 40 is supported on the upper surface of the jig plate 51 and coupled with the jack bolt 10. When the fastening bolt 30 is fastened to the jack bolt 10, the jack bolt 10 rotates together with the fastening bolt 30 and can be inserted into the jig plate 51. In this case, the height of the jack bolt 10 is different so that the forged material 53 cannot be supported. To prevent this, adjust the height of the jack bolt 10 before fastening the fastening bolt 30 to the jack bolt 10. Then, the nut 40 is fastened to the jack bolt 10 so as to be supported on the top of the jig plate 51. In addition, when the fastening bolt 30 is fastened to the jack bolt 10, the fastening bolt 30 and the jack bolt 10 may be fastened while the jack bolt 10 is fixed.

본 실시예의 경우 잭볼트(10)의 구면홈(12)에 구면와셔(20)를 삽입하여 너트(40)를 체결한 후 잭볼트(10)를 단조소재(53)를 고정시킬 위치의 지그판(51)에 체결한다. 그리고 단조소재(53)를 지그판(51)에 올려 놓는다.In this embodiment, after inserting the spherical washer 20 into the spherical groove 12 of the jack bolt 10 and fastening the nut 40, the jack bolt 10 is placed on the jig plate at the position to fix the forged material 53. (51). Then, the forged material 53 is placed on the jig plate 51.

구면와셔(20)의 상부면(23)이 단조소재(53)를 지지하도록 잭볼트(10)의 높이를 조절한다. 이때 단조소재(53)의 하부면이 도 5에 도시된 바와 같이 지그판(51)과 평행하지 않더라도 구면와셔(20)가 구면홈(12)에서 회전이 가능하므로 구면와셔(20)의 상부면(23)이 단조소재(53)의 하부면을 지지할 수 있다. 구면와셔(20)의 상부면(23)이 단조소재(53)의 하부면을 지지하면 너트(40)를 이동시켜 지그판(51)의 상부에 맞닿도록 한다. 그리고 체결볼트(30)를 단조새재(53)와 구면와셔(20)를 관통하여 나사홈(15)에 체결하여 단조소재(53)를 고정시킨다. 물론 이때에는 단조소재(53)에 체결볼트(30)가 삽입될 수 있도록 구멍이 형성되어야 한다.The height of the jack bolt 10 is adjusted so that the upper surface 23 of the spherical washer 20 supports the forged material 53. At this time, even if the lower surface of the forged material 53 is not parallel to the jig plate 51 as shown in FIG. 5, since the spherical washer 20 can rotate in the spherical groove 12, the upper surface of the spherical washer 20 (23) can support the lower surface of the forged material (53). When the upper surface 23 of the spherical washer 20 supports the lower surface of the forged material 53, the nut 40 is moved so as to come into contact with the upper part of the jig plate 51. Then, the fastening bolt 30 is passed through the forged member 53 and the spherical washer 20 and fastened to the screw groove 15 to fix the forged material 53. Of course, at this time, a hole must be formed in the forged material 53 so that the fastening bolt 30 can be inserted.

구면와셔(20)의 관통공(25)이 체결볼트(30)의 체결볼트나사부(31)의 직경 및 나사홈(15)의 직경보다 크게 형성되므로 구면와셔(20)가 구면홈(12)에서 회전하더라도 체결볼트(30)의 체결볼트나사부(31)가 관통공(25)을 관통하여 삽입될 수 있다.Since the through hole 25 of the spherical washer 20 is formed larger than the diameter of the fastening bolt thread 31 of the fastening bolt 30 and the diameter of the screw groove 15, the spherical washer 20 is formed in the spherical groove 12 Even when rotating, the fastening bolt threaded portion 31 of the fastening bolt 30 can be inserted through the through hole 25 .

따라서, 본 실시예에 의하면, 단조소재(53)의 하부면이 임의의 각도로 기울어져있더라도 하부면을 면삭가공하지 않고 지그판(51)에 고정시킬 수 있다.Therefore, according to this embodiment, even if the lower surface of the forged material 53 is inclined at an arbitrary angle, the lower surface can be fixed to the jig plate 51 without chamfering.
