Description

호닝머신의 가공품 회전방지용 지그{Jig for preventing rotation of work in the honing machine}Jig for preventing rotation of work in the honing machine

본 발명은 호닝머신의 가공품 회전방지용 지그에 관한 것으로서, 더욱 상세하게는 차량의 변속기용 스피드기어의 내경을 연마 가공하는 호닝머신에서, 스피드 기어가 호닝작업시 회전되지 않도록 견고하게 잡아줄 수 있도록 한 호닝머신의 가공품 회전방지용 지그에 관한 것이다.The present invention relates to a jig for preventing rotation of a workpiece of a honing machine, and more particularly, in a honing machine for polishing an inner diameter of a speed gear for a transmission of a vehicle, so that the speed gear can be firmly held so as not to rotate during the honing operation. The present invention relates to a jig for preventing rotation of a workpiece of a honing machine.

통상적으로, 차량용 수동변속기의 스피드기어(Speed gear)의 내경을 가공시에 호닝머신(honing machine)을 사용하고 있는 바, 상기 호닝머신의 호닝툴(honing tool)이 회전하면서 스피드기어의 내경에 대한 호닝 가공시, 호닝툴과 함께 회전되지 않도록 스피드기어를 회전방지용 지그로 고정시키게 된다.In general, a honing machine is used to process an inner diameter of a speed gear of a vehicle manual transmission. As a honing tool of the honing machine rotates, When honing, the speed gear is fixed with a jig to prevent rotation with the honing tool.

첨부한 도 3은 종래에 호닝머신의 가공품 회전방지용 지그를 나타내는 평면도로서, 종래의 지그(10b)는 중앙에 홀을 갖는 장착단(12)과, 이 장착단(12)의 양측 저면에 볼팅등으로 체결되는 고정단(14)으로 구성되어 있다.FIG. 3 is a plan view showing a conventional jig for preventing rotation of a workpiece of a honing machine, and the conventional jig 10b includes a mounting end 12 having a hole in the center and bolts on both bottom surfaces of the mounting end 12. It is composed of a fixed end 14 is fastened by.

상기 지그(10b)의 장착단(12)은 호닝머신(16)에 장착되는 부위이고, 그 중앙의 홀(18)은 상기 호닝머신의 상부가이드(22)가 삽입되는 부분이며, 특히 상기 고정단(14)은 수직 절곡된 형상으로서, 그 하단끝에는 안쪽으로 돌출된 핀(26)이 일체로 형성되어 있다.The mounting end 12 of the jig 10b is a portion to be mounted to the honing machine 16, and the hole 18 in the center thereof is a portion into which the upper guide 22 of the honing machine is inserted. 14 is a vertically bent shape, and the pin 26 which protrudes inward is integrally formed in the lower end.

이에, 첨부한 도 4에 도시한 바와 같이, 상기 지그(10b)의 장착단(12)을 호닝머신(16)에 장착하는 동시에 그 중앙의 홀(18)을 통하여 상부가이드(22)가 하강하며 삽입되는 상태가 된다.Accordingly, as shown in FIG. 4, the mounting guide 12 of the jig 10b is mounted on the honing machine 16 and the upper guide 22 descends through the hole 18 in the center thereof. It will be inserted.

또한, 상기 상부가이드(22)의 아래쪽에 위치한 상기 호닝머신(10b)의 베이스면에는 하부가이드(24)가 상승 가능하게 장착되어 있다.In addition, the lower guide 24 is mounted to the base surface of the honing machine 10b located below the upper guide 22 so as to be lifted up.

한편, 차량용 수동변속기의 스피드기어(30)는 첨부한 도 6에 도시한 바와 같이, 클러치기어(34)와 주기어(32)가 일체로 되어 있는데, 보다 작은 직경의 클러치기어(34)가 주기어(32)의 일면에 부착된 형태로 되어 있다.On the other hand, the speed gear 30 of the manual transmission for a vehicle, as shown in Figure 6, the clutch gear 34 and the main gear 32 is integrated, the clutch gear 34 of a smaller diameter is the cycle It is a form attached to one surface of the fish 32.

따라서, 도 5의 흐름도와 같이, 상기 스피드기어(30)를 호닝머신의 베이스면으로 이송 반입후, 상기 하부가이드(22)가 상승하여 스피드기어(30)의 주기어(32) 저부의 보스면을 받쳐주는 동시에 상기 상부가이드(22)가 하강하는 동시에 지그(10b)의 홀(18)을 통하여 삽입되면서 클러치기어(34) 상면의 보스면을 눌러주어 클램핑이 된다.Therefore, as shown in the flowchart of FIG. 5, after the transfer of the speed gear 30 to the base surface of the honing machine, the lower guide 22 is raised to the boss surface of the bottom of the main gear 32 of the speed gear 30. At the same time, the upper guide 22 descends and is inserted through the hole 18 of the jig 10b while pressing the boss surface of the upper surface of the clutch gear 34 to clamp.

동시에, 상기 지그(10b)의 고정단(14)에 일체로 형성되어 있는 두 개의 핀(26)이 상기 클러치기어(34)의 치에 끼이면서 전체 스피드기어(30)를 회전되지 않게 잡아주게 된다.At the same time, two pins 26 integrally formed at the fixed end 14 of the jig 10b are caught by the teeth of the clutch gear 34 to hold the entire speed gear 30 in a non-rotating manner. .

이렇게 스피드기어(30)를 고정시킨 후, 호닝머신(16)의 호닝툴(20)이 상기 상부가이드(22)의 홀을 통하여 하강하여, 위치 결정된 스피드기어(30)의 내경을 면가공하게 되고, 이때 호닝툴(20)은 상하 및 회전 운동을 하면서 스피드기어의 내경을 가공하게 된다.After fixing the speed gear 30 in this way, the honing tool 20 of the honing machine 16 is lowered through the hole of the upper guide 22, so as to face the inner diameter of the positioned speed gear 30. At this time, the honing tool 20 is to process the inner diameter of the speed gear while moving up and down and rotation.

그러나, 종래의 스피드기어에 대한 호닝 작업시 다음과 같은 단점이 있었다.However, in the honing operation of the conventional speed gear, there were the following disadvantages.

즉, 스피드기어의 내경을 가공하고자, 스피드기어의 클러치기어의 치에 지그의 양쪽에 있는 핀이 끼워지게 하여, 스피드기어가 호닝툴과 함께 회전되지 않도록 하였는 바, 호닝툴 회전과 함께 2개의 핀에 너무 과다한 부하가 발생하여, 핀이 조기에 마모되는 단점이 있었다.In other words, in order to process the inner diameter of the speed gear, the pins on both sides of the jig are fitted to the teeth of the clutch gear of the speed gear so that the speed gear is not rotated together with the honing tool. Too much load occurred on the pins, causing the pins to wear prematurely.

상기 지그의 핀이 조기에 마모됨에 따라, 공구비 상승 및 호닝작업시 스피드 기어의 단면 직각도 가공불량을 초래하는 단점이 있었다.As the pins of the jig are worn out prematurely, there is a disadvantage that the cross-sectional right angle of the speed gear causes a machining failure during the increase of the tool cost and the honing operation.

따라서, 본 발명은 상기와 같은 단점을 해결하기 위하여, 호닝머신에 장착되어 스피드기어를 잡아주는 종래의 지그 구조를 개선하여, 스피드기어가 호닝툴과 함께 회전되지 않도록 견고하게 잡아줄 수 있도록 한 호닝머신의 가공품 회전방지용 지그를 제공하는데 그 목적이 있다.Therefore, in order to solve the above disadvantages, the present invention improves the conventional jig structure that is mounted on the honing machine to hold the speed gear, so that the speed gear can be firmly held so as not to rotate with the honing tool. It is an object of the present invention to provide a jig for preventing rotation of a workpiece of a machine.

상기한 목적을 달성하기 위한 본 발명은:The present invention for achieving the above object is:

호닝머신에 장착되는 장착단과, 이 장착단의 양측 저면에 체결되는 고정단으로 구성되어 있는 호닝머신의 가공품 회전방지용 지그에 있어서,In the jig for preventing the rotation of the workpiece of the honing machine consisting of a mounting end mounted to the honing machine and a fixed end fastened to both bottom surfaces of the mounting end,

상기 고정단(14)에 중앙에 홀이 형성되고 그 내경면에 클러치기어(34)의 전체치(齒)와 맞물리는 전치(全齒)(36)가 형성된 회전방지체(40)를 일체로 부착하여서 된 것을 특징으로 한다.A hole is formed in the center of the fixed end 14, and an anti-rotation body 40 having an anterior tooth 36 engaged with the entire tooth of the clutch gear 34 is formed on the inner diameter surface thereof. It is characterized by being attached.

여기서 본 발명의 실시예를 첨부도면을 참조로 더욱 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

첨부한 도 1은 본 발명에 따른 호닝머신의 회전방지용 지그를 나타내는 평면도이고, 도 2는 호닝머신의 회전방지용 지그의 설치상태를 나타내는 단면 사시도로서, 본 발명의 지그(10a)는 중앙 부분에 원형의 홀(18)을 갖는 장착단(12)과, 이 장착단(12)의 양측 저면에 체결되는 고정단(14)으로 구성되어 있다.1 is a plan view showing the anti-rotation jig of the honing machine according to the present invention, Figure 2 is a cross-sectional perspective view showing the installation of the anti-rotation jig of the honing machine, jig (10a) of the present invention is circular in the center portion The mounting end 12 which has the hole 18 of this, and the fixed end 14 fastened to both bottom surfaces of this mounting end 12 are comprised.

상기 고정단(14)은 수직 절곡된 형상으로서, 그 하단끝 내면에 원형 고리 형상의 회전방지체(40)가 일체로 부착된다.The fixed end 14 is a vertically bent shape, the anti-rotation body 40 of the circular ring shape is integrally attached to the inner surface of the lower end.

특히, 상기 회전방지체(40)의 내경면에는 전치(全齒)(36)가 형성되어, 상기 스피드기어(30)의 클러치기어(34)의 전체치(齒)와 맞물리게 된다.In particular, an anterior tooth 36 is formed on the inner diameter surface of the rotation preventing body 40 so as to be engaged with the entire tooth of the clutch gear 34 of the speed gear 30.

따라서, 상술한 바와 같이, 스피드기어(30)를 호닝머신(16)의 베이스면에 반입후, 상기 하부가이드(24)가 상승하여 스피드기어(30)의 주기어(32) 저부의 보스면을 받쳐주는 동시에 상기 상부가이드(22)가 하강하는 동시에 상기 지그(10a)의 장착단(12)의 홀(18)을 통하여 삽입되면서 클러치기어(34) 상면의 보스면을 눌러주어 클램핑이 된다.Therefore, as described above, after bringing the speed gear 30 into the base surface of the honing machine 16, the lower guide 24 is raised to raise the boss surface of the bottom of the main gear 32 of the speed gear 30. At the same time, the upper guide 22 descends and is inserted through the hole 18 of the mounting end 12 of the jig 10a while pressing the boss surface of the upper surface of the clutch gear 34 to be clamped.

동시에, 상기 지그(10a)의 고정단(14)에 일체로 형성되어 있는 상기 회전방지체(40)의 전치(全齒)(36)가 상기 클러치기어(34)의 전체치(齒)와 맞물리게 되어, 결국 스피드기어(30)를 회전되지 않게 견고히 잡아주게 된다.At the same time, the front teeth 36 of the anti-rotation body 40 formed integrally with the fixed end 14 of the jig 10a are engaged with the entire teeth of the clutch gear 34. As a result, the speed gear 30 is firmly held so as not to rotate.

즉, 변속기의 조립 상태에서, 변속시 싱크로나이즈 슬리브와 클러치기어가 치합되는 원리와 같이, 스피드 기어(30)는 용이하게 고정된 상태가 되는 것이다.That is, in the assembling state of the transmission, as in the principle that the synchronizer sleeve and the clutch gear are engaged at the time of shifting, the speed gear 30 is easily fixed.

이렇게 본 발명의 회전방지체(40)가 스피드기어(30)를 견고하게 잡아준 상태에서, 호닝머신(16)의 호닝툴(20)이 상기 상부가이드(22)의 홀(18)을 통하여 하강하여, 위치 결정된 스피드기어(30)의 내경을 상하 및 회전 운동을 하면서 가공하게 되는 바, 종래와는 달리 스피드기어(30)가 견고하게 고정된 상태이므로, 호닝툴의 회전시 걸리는 토크 및 과도한 부하에도 그 고정상태를 견고히 유지할 수 있고, 또 한 호닝툴의 회전과 함께 스피드기어가 회전되는 현상이 용이하게 방지되어, 결국 정밀한 호닝 가공도를 얻을 수 있게 된다.Thus, while the anti-rotation body 40 of the present invention firmly holds the speed gear 30, the honing tool 20 of the honing machine 16 is lowered through the hole 18 of the upper guide 22 In order to process the inner diameter of the positioned speed gear 30 while moving up and down, the speed gear 30 is firmly fixed unlike the conventional one, so that the torque and excessive load required when the honing tool is rotated are also fixed. The fixed state can be firmly maintained, and the phenomenon in which the speed gear rotates with the rotation of the honing tool can be easily prevented, so that a precise honing degree can be obtained.

이상에서 본 바와 같이, 본 발명에 따른 호닝머신의 회전방지용 지그에 의하면, 호닝 작업을 위하여 변속기용 스피드기어를 견고하게 고정시킴으로써, 정밀한 호닝 가공도를 얻을 수 있고, 또한 종래에 수명이 짧은 지그에 비하여 그 수명이 반영구적이므로, 교체 작업을 위한 공구소모 및 가공비용을 절감할 수 있다.As described above, according to the anti-rotation jig of the honing machine according to the present invention, by firmly fixing the speed gear for the transmission for the honing operation, it is possible to obtain a precise honing work degree, and in the conventional jig short life In comparison, since the service life is semi-permanent, tool consumption and machining cost for replacement work can be reduced.
