본 고안은 풀로어힌지용 캠과 캠의 고정구조에 관한 것으로 특히 캠축에 형성된 체결돌조가 캠의 축공에 형성한 고정요홈에 삽입 체결되게 한 플로어힌지용 캠축의 구조에 관한 것이다.The present invention relates to a cam structure for a full-row hinge and a cam cam fixing structure, and more particularly, to a structure of a camshaft for a floor hinge that the fastening protrusion formed in the cam shaft is inserted into the fixing groove formed in the cam shaft hole.
종래 캠에 고정되는 플로어힌지의 캠축은 통상 단순원봉형 캠축의 하단을 캠에 형성된 원형축공에 끼워넣고 그 축과 캠의 연접부를 용착고정하거나 또는 캠축의 하단에 형성한 4각단면부를 캠에 형성된 구형(矩形)축공에 끼우고 같은 방법으로 용접 고정하는 방법이 알려져 있다.The camshaft of the floor hinge fixed to the conventional cam is usually formed by inserting the lower end of the simple cylindrical camshaft into a circular shaft hole formed in the cam and welding the joint between the shaft and the cam, or forming a quadrilateral cross section formed at the lower end of the camshaft. It is known to insert a spherical shaft hole and to fix the welding in the same manner.
그러나 이와같은 방법으로 캠축과 캠을 체결고정함에 있어서는 번거롭고 까다로운 별도의 용접가공공정을 필요로 하게되어 생산성의 저하요인을 갖게될 뿐만아니라, 그 용접과정에서 열처리 가공된 캠축과 캠 소재의 조직에 변화를 주게되어 요구되는 강도를 유지할 수 없게 되므로 캠의 작동시 고정부위에 가해지는 힘에 의하여 그 고정부위가 쉽게 파손되는 등의 결함과 문제점이 있었다.However, in this way, fastening and fixing the camshaft and cam requires a separate and cumbersome welding process, which leads to a decrease in productivity and changes in the structure of the camshaft and cam material heat-treated during the welding process. Since it is not possible to maintain the required strength, there was a defect and a problem such that the fixing portion is easily broken by the force applied to the fixing portion during the operation of the cam.
본 고안은 이와같은 종래 캠축과 캠의 고정방법이 가지는 제반 결합 및 문제점을 감안하여 안출한 것으로, 상호 체결 고정되는 캠축의 단부상에 캠의 축공에 형성된 다수개의 고정요홈에 체결조를 대응되게 체결돌조를 형성하고 이들 체결돌조와 고정요홈을 강제 끼워 맞춤과 캠축과 캠을 체결고정함으로써 종래와 같은 용착공정을 배제함과 아울러 캠축과 캠간의 체결력을 높일 수 있게 한 것인바, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the general coupling and problems of the conventional cam shaft and the method of fixing the cam, the fastening tank corresponding to a plurality of fixing grooves formed in the shaft hole of the cam on the end of the cam shaft to be fastened to each other correspondingly By forming the protrusions and forcibly fitting the fastening protrusions and the fixing grooves and fastening the cam shafts and cams, it is possible to eliminate the conventional welding process and to increase the fastening force between the cam shafts and the cams. When described in detail as follows.
제 1 도는 본 고안의 일실시예에 의한 캠축과 캠의 고정구조를 보인 것으로 캠(2)과 연결되는 캠축(1)하단의 소경부(1')상측주벽에 삼각 단면 형상을 가지는 다수개의 체결돌조(1a)를 소경부(1')의 둘레를 따라 등간격으로 돌출형성하고 그 캠축(1)의 하단이 끼워지는 캠(2)의 축공(2') 내주면에는 상기 각 체결돌조(1a)에 대응하는 다수개의 고정요홈(2a)을 연속적으로 형성하여 캠축(1)과 캠(2)의 결합에 따랄 상기 각 체결돌조(1a)가 각 고정요홈(2a)에 강제적으로 삽입고정되게 한 것이다.FIG. 1 is a view illustrating a cam shaft and a cam fixing structure according to an embodiment of the present invention, and a plurality of fastenings having a triangular cross-sectional shape on an upper circumferential wall of the small diameter portion 1 'at the lower end of the cam shaft 1 connected to the cam 2 are shown in FIG. Each of the fastening protrusions 1a is formed on the inner circumferential surface of the shaft hole 2 'of the cam 2 in which the protrusions 1a are formed at equal intervals along the circumference of the small diameter portion 1' and the lower end of the cam shaft 1 is fitted. Forming a plurality of fixing grooves (2a) corresponding to the successive each of the fastening protrusions (1a) according to the combination of the cam shaft (1) and the cam (2) forcibly inserted into each fixing groove (2a). .
도면중 제 2 도의 11는 상기 캠(2)과 로울러(12) (12')를 통하여 접촉되어 그 캠(2)의 회전에 따라 작동되는 압착구를 보인 것이고 13은 그 압착구(11)를 탄력설치하는 스프링이며 10은 플로어힌지 본체 케이스를 보인 것이다.11 of FIG. 2 shows a crimping hole which is contacted with the cam 2 through the rollers 12 and 12 'and operated according to the rotation of the cam 2, and 13 shows the crimping hole 11. It is spring to install elasticity and 10 shows floor hinge body case.
이상과 같은 체결고정구조를 가지는 본 고안에 있어서는 캠축(1)의 각 체결돌조(1a)가 캠공(2')의 각 고정요홈(2a)에 강제 압입방식으로 간단히 체결고정되므로 그 고정작업이 간편용이하고 상호 체결된 회전축(1)과 캠(2)의 고정상태를 견고하고 확실하게 유지할 수 있게되며, 이들의 고정부에 가해지는 힘이 각 돌조(1a)와 요홈(2a)을 통하여 고르게 분산 전달되므로, 캠(2)의 구동에 따라 작용되는 외력에 의한 그 고정부 및 캠(2)의 파손요인을 갖지 않게 된다.In the present invention having a fastening fixing structure as described above, each fastening protrusion 1a of the cam shaft 1 is simply fastened and fixed to each fixing recess 2a of the cam hole 2 'by a forced press method, so that the fixing work is easy. It is possible to easily and securely maintain the fixed state of the rotating shaft 1 and the cam 2, which are fastened to each other, and the force applied to these fixing parts is evenly distributed through each protrusion 1a and the groove 2a. Since it is transmitted, it does not have the damage factor of the fixing part and the cam 2 by the external force acting according to the drive of the cam 2.
한편, 이상의 실시예에서의 캠축(1)의 체결돌조(1a)와 캠축공(1')의 고정요홈(1a)이 각기 삼각단면으로 된 예를 도시하고 설명하였으나 본 고안을 실시함에 있어서 각 체결돌조(1a)와 고정요홈(2a)의 형상과 구조는 제 3a,b,c 도에 각기 도시한 바와같이 U자상, 사다리꼴, 반원형등 각 돌조(1a)와 요홈(2a) 이 상호 긴밀히 맞물려 체결될 수 있는 범위내에서 여러가지의 형태로 변형실시될 수가 있다.On the other hand, in the above embodiment shown and described an example in which the fastening protrusion 1a of the camshaft 1 and the fixing groove 1a of the camshaft hole 1 'are triangular cross sections, respectively, The shape and structure of the protrusion 1a and the fixed recess 2a are closely interlocked with each other such as the U-shaped, trapezoidal, semicircular, etc. Modifications can be made in various forms within the scope possible.
상술한 바와같은 본 고안에 의한 캠축과 캠의 고정구조는 별도 제작되는 캠축(1)과 캠(2)의 가공시 그 결합부인 캠축(1)의 소경부(1')와 캠축공(2')에 상호 대응되는 체결돌조(1a)와 고정요홈(2a)을 각기 일체로 형성하여 그 캠축(1)의 체결돌조(1a)를 캠(2)의 고정요홈(2)에 강데 끼워맞춤으로써 캠축(1)과 캠(2)을 견고하고 확실하게 체결고정할 수 있게 되는 것이므로, 종래와 같은 용착작업을 배제하여 그 생산성을 월등히 향상시킬 수 있게 됨과 아울러 열처리 가공된 캠축(1)과 캠(2)의 조직에 변화요인을 갖지 않게되므로 요구되는 강도를 그대로 유지할 수 있게될 뿐만 아니라, 이들 체결돌조(1a)와 고정요홈(2a)이 가지는 체결구조에 있어서 캠축(1)과 캠(2)의 고정부에 작용되는 힘을 고르게 분산시킬 수 있게 됨으로써 캠ㅂ(2)에 가해지는 외력으로부터 그 고정부 또는 캠(2)의 파손될 우려를 배제하여 캠축(1)과 캠(2)의 사용수명을 연장시킬 수 있게 되는 등의 효과가 있다.As described above, the cam shaft and the cam fixing structure according to the present invention have a small diameter portion 1 'and a camshaft hole 2' of the camshaft 1, which are engaging portions thereof, when the camshaft 1 and the cam 2 are separately manufactured. The camshafts 1a and the fixing grooves 2a corresponding to each other are formed integrally with each other, and the fastening protrusions 1a of the camshaft 1 are fitted to the fixing grooves 2 of the cam 2 by force. Since the fastening and fastening of the cam 1 and the cam 2 can be securely and reliably secured, the cam shaft 1 and the cam 2, which have been heat-treated, can be improved significantly by eliminating conventional welding operations. Since there is no change factor in the structure, the cam shaft 1 and the cam 2 of the cam shaft 1 and the cam 2 in the fastening structure of the fastening protrusion 1a and the fixing recess 2a can be maintained. It is possible to evenly distribute the force acting on the fixing part, thereby fixing it from the external force applied to the camshaft (2). Or there is an effect, such as to eliminate the damaged of the cam (2) being able to extend the service life of the cam shaft (1) and the cam (2).
