Description
본 고안은 크로스멤버 내구성시험용 마운팅 지그에 관한 것으로, 좀더 상세하게는 실차주행조건에 맞추어서 크로스멤버의 강도를 시험하는 내구성시험에 있어서 크로스멤버로부터 가해지는 시험하중을 충분히 견딜 수 있도록 하는 크로스멤버 내구성시험용 마운팅 지그에 관한 것이다.The present invention relates to a mounting jig for cross member durability test, and more specifically, for cross member durability test that can withstand the test load applied from the cross member in the durability test for testing the strength of the cross member according to the actual driving conditions. It is about the mounting jig.
일반적으로 크로스멤버는 강도를 높이기 위한 차체의 골격으로 사용되고 있다. 즉, 자동차가 험로주행시나 충돌사고시, 차체가 전후방향이나 좌우방향으로 비틀리거나 휘어지는 것을 방지하기 위하여 사용되고 있으며 자동차의 진행방향에 대해 직각방향으로 설치되는 것이다.In general, the cross member is used as a skeleton of the vehicle body to increase the strength. That is, the vehicle is used to prevent the vehicle body from twisting or bending in the front-rear direction or the left-right direction at the time of driving in a rough road or a crash accident, and is installed at right angles to the traveling direction of the car.
종래에는 상기한 바와같이 실제 차량에 장착되는 크로스멤버를 시험하기 위해 도 1에 도시된 바와같이, 실차조건을 고려한 실차부품과 직경이 동일한 마운팅 지그를 다수개 사용하여 크로스멤버(11)의 강도를 시험하였다. 이는 기대(41)에 지지된 지그의 상부에 형성된 볼트부(32)로 크로스멤버(11)에 형성된 결합공(12)이 삽입되도록 한 후, 이 볼트부(32)에 너트(21)를 체결하며, 크로스멤버(11)에 형성된 다른 결합공(12)에도 전술한 마운팅 지그와 동일한 구조의 다른 지그를 삽입한 후 너트(21)로 체결함으로써, 크로스멤버(11)를 고정하였다. 이때, 전술한 각각의 마운팅 지그의 지지부(33)는 기대(41)에 지지되도록 한다.Conventionally, as described above, in order to test a cross member mounted on an actual vehicle, as shown in FIG. 1, the strength of the cross member 11 is increased by using a plurality of mounting jigs having the same diameter as the actual vehicle parts considering the actual vehicle conditions. Tested. This allows the coupling hole 12 formed in the cross member 11 to be inserted into the bolt portion 32 formed on the top of the jig supported by the base 41, and then tightens the nut 21 to the bolt portion 32. In addition, another jig having the same structure as the above-described mounting jig is inserted into the other coupling hole 12 formed in the cross member 11 and then fastened with the nut 21 to fix the cross member 11. At this time, the support part 33 of each mounting jig described above is supported by the base 41.
이와같이 지그에 고정된 크로스멤버(11)의 바디에 충격을 가함으로써 강도에 대한 크로스멤버(11)의 내구성을 시험하도록 하였는데, 종래의 내구성시험용 마운팅 지그는 계속적으로 크로스멤버(11)가 교체장착되어 시험되고, 내구성시험 중 크로스멤버(11)의 바디가 크게 변형되는 경우, 충격에 대해 취약부위인 결합부분에 균열이 발생하는 일이 빈번하다.In this way, the durability of the cross member 11 to the strength was tested by applying an impact to the body of the cross member 11 fixed to the jig, the conventional durability test mounting jig is continuously replaced with the cross member 11 If the body of the crossmember 11 is greatly deformed during the test and durability test, cracks are frequently generated at the joints that are vulnerable to impact.
본 고안은 휘어짐, 뒤틀림 등의 강도를 시험하는 크로스멤버의 내구성시험에 있어서 크로스멤버를 고정하는 마운팅 지그의 결합부가 보다 견고하게 되도록 구조를 개선한 크로스멤버 내구성시험용 마운팅 지그를 제공하려는 것이다.The present invention is to provide a cross member durability test jig for improving the structure so that the coupling portion of the mounting jig for fixing the cross member in the durability test of the cross member for testing the strength of bending, distortion, and the like.

본 고안에 따르면, 중반부에는 외경이 상협하광으로 완곡을 이룬 와셔삽입부(31)가 형성되어 내경이 상협하광의 완곡면으로 형성된 와셔(29)가 끼워지도록 하고, 상기 와셔삽입부(31)에서 상측으로 연장되는 외주면의 상단부에는 크로스멤버(11)의 결합공(12)을 삽입한 후 너트(21)로 체결하는 볼트부(32)가 형성되며, 하단부에는 기대(41)에 지지되는 지지부(33)가 형성되는 것을 특징으로 하는 크로스멤버 내구시험용 마운팅 지그가 제공된다.According to the present invention, the washer insert portion 31 is formed in the middle portion of the bent light in the upper and lower side to form a washer 29 formed in the curved surface of the upper and lower side light, so that the washer insert portion 31 in the The upper end of the outer circumferential surface extending to the upper side is formed with a bolt portion 32 is inserted into the coupling hole 12 of the cross member 11 and fastened with the nut 21, the lower end of the support portion (supported by the base 41 ( 33) there is provided a mounting jig for crossmember endurance test.
이하, 본 고안의 바람직한 실시예를 도면을 참조하여 더욱 구체적으로 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.
도 2는 본 고안에 의한 마운팅 지그의 사용상태를 보인 측단면도로서, 지그는 대략 원기둥형으로 이루어지며, 중반부의 외경이 상협하광의 완곡면으로 와셔삽입부(31)가 형성되고, 상기 와셔삽입부(31)에서 상측으로 연장되는 외주면의 상단부에는 크로스멤버(11)의 결합공(12)을 삽입한 후 너트(21)로 체결하는 볼트부(32)가 형성되며, 하단부에는 기대(41)에 지지되는 지지부(33)가 형성된다. 상기 와셔삽입부(31)에는 내경이 상협하광의 완곡면으로 형성된 와셔(29)가 끼워지게 된다. 이와같이 지그의 중반부의 외주면인 와셔삽입부(31)에 와셔(29)를 끼운 후 크로스멤버(11)의 결합공(12)을 관통하여 끼우고, 이 결합공(12)을 관통한 지그의 볼트부(32)에 너트(21)로 체결하는 구조로 이루어진다. 이와같은 구조의 마운팅 지그에 크로스멤버(11)를 고정할 수 있도록 하려면, 크로스멤버(11)에 형성된 다수의 결합공(12)의 위치에 대응하는 위치에 본 고안의 마운팅 지그를 다수개 배치하도록 한다.Figure 2 is a side cross-sectional view showing a state of use of the mounting jig according to the present invention, the jig is made of a substantially cylindrical shape, the outer diameter of the middle portion washer insert portion 31 is formed in the curved surface of the upper and lower light, the washer insert The upper end portion of the outer circumferential surface extending from the upper portion 31 to the upper side is formed with a bolt portion 32 is inserted into the coupling hole 12 of the cross member 11 and fastened to the nut 21, the lower end portion 41 Support portion 33 is supported. The washer insertion portion 31 is fitted with a washer 29 formed of a curved surface of the upper and lower light of the inner diameter. In this way, the washer 29 is inserted into the washer insert 31, which is the outer circumferential surface of the middle of the jig, and then inserted through the coupling hole 12 of the cross member 11, and the bolt of the jig penetrated through the coupling hole 12. It is made of a structure for fastening with the nut 21 to the portion (32). In order to be able to fix the cross member 11 to the mounting jig of such a structure, to arrange a plurality of mounting jig of the present invention in a position corresponding to the position of the plurality of coupling holes 12 formed in the cross member 11 do.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
본 고안의 마운팅 지그를 크로스멤버(11)에 형성된 결합공(12)의 위치에 대응하여 기대(41)에 다수개를 배치하여 고정시키면, 이 지그들에 크로스멤버(11)를 고정할 수 있게 된다. 이는 지그의 중반부에 형성되어 외경이 상협하광의 완곡면을 이룬 와셔삽입부(31)에 내경이 상협하광의 완곡면으로 형성된 와셔(29)를 끼운 후, 상기 와셔삽입부(31)에서 상측으로 연장되는 외주면에 크로스멤버(11)에 형성된 결합공(12)을 삽입하여 이미 삽입된 상기 와셔(29)의 상부면에 크로스멤버(11)의 하측 주연부가 안착되도록 하고, 상기 크로스멤버(11)의 상측주연부에 안착될 때까지 지그상단의 볼트부(32)에 너트(21)를 체결한다. 휘어짐, 뒤틀림 등의 강도를 시험하는 크로스멤버(11)의 내구시험은 전술한 바와같이, 본 고안의 마운팅 지그에 크로스멤버(11)를 체결하여 고정한 후 행하게 되며, 이때, 본 고안의 마운팅 지그는 와셔삽입부(31)로 인해 직경이 완곡을 이루면서 커지므로 종래의 것에 비해 크로스멤버(11)를 통해 전달되는 충격에 견디는 힘이 커지게 된다. 따라서, 휘어짐, 뒤틀림 등의 강도를 시험하는 크로스멤버(11)의 내구성시험시 지그의 균열을 방지할 수 있게 된다.When the mounting jig of the present invention is disposed and fixed to the base 41 corresponding to the position of the coupling hole 12 formed in the cross member 11, the cross member 11 can be fixed to these jigs. do. It is formed in the middle of the jig, the outer diameter of the washer insert portion 31, the outer diameter of which is a curved surface of the upper and lower down light, the inner diameter of the washer 29 is formed into a curved surface of the upper and lower down light, and then the washer insertion portion 31 upward Inserting the coupling hole 12 formed in the cross member 11 to the outer peripheral surface extending so that the lower peripheral portion of the cross member 11 is seated on the upper surface of the washer 29 is already inserted, the cross member 11 Tighten the nut 21 to the bolt 32 on the top of the jig until it rests on the upper periphery of the jig. Endurance test of the cross member 11 to test the strength of the bending, twisting, etc., as described above, is performed after fastening the cross member 11 to the mounting jig of the subject innovation after fixing, the mounting jig of the subject innovation Due to the washer insert portion 31 becomes larger in diameter as the curvature increases, the force to withstand the shock transmitted through the cross member 11 is increased compared to the conventional. Therefore, it is possible to prevent cracking of the jig during the durability test of the cross member 11 for testing the strength of warpage and warpage.
본 고안은 크로스멤버를 고정하는 마운팅 지그의 결합부위가 보다 견고하게 되도록 구조를 개선함으로써 크로스멤버의 내구성시험시 지그의 손상을 방지하는 유용한 것이다.The present invention is useful to prevent the damage of the jig during the durability test of the cross member by improving the structure so that the coupling portion of the mounting jig fixing the cross member more secure.
