Description

크랭크 축의 핀부 위상 설정 장치Pin part phase setting device of the crankshaft

본 발명은 크랭크 축의 핀부 위상 설정 장치에 관한 것으로서, 보다 구체적으로는 크랭크 축의 핀부 위상을 180 °로 반전시켜 설정하는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crankshaft pin phase setting device, and more particularly, to an apparatus for inverting and setting a crankshaft pin phase by 180 degrees.

일반적으로, 크랭크 축은 피스톤의 직선 운동력을 커넥팅 로드를 통해 전달받아 회전 운동력으로 전환시키는 것으로서, 엔진 기통수에 따라 4기통일 경우에는4개의 커넥팅 로드가 연결되고, 6기통일 경우에는 6개의 커넥팅 로드가 동시에 연결된다. 또한, 크랭크 축의 고속 회전운동을 지지하기 위한 메탈 베어링이 크랭크 축에 끼워진다.In general, the crankshaft is to convert the linear momentum force of the piston through the connecting rod to the rotational force, depending on the number of engine cylinders, four connecting rods are connected in the case of four cylinders, six connecting rods in the case of six cylinders Are connected at the same time. In addition, a metal bearing for supporting the high speed rotational movement of the crankshaft is fitted to the crankshaft.

그런데, 크랭크 축을 가공하는 공작 기계는, 커넥팅 로드가 연결되는 크랭크 축의 1번 핀부가 수직선을 기준으로 정확히 하부에 설정되어 있어야만 가공이 가능한 구조로 되어 있다.By the way, the machine tool which processes a crankshaft has a structure which can be processed only when pin 1 of the crankshaft to which a connecting rod is connected is set exactly at the lower part with respect to a vertical line.

따라서, 공작 기계로 크랭크 축을 가공하기 전에, 반드시 위상 설정 장치를 이용해서 크랭크 축의 1번 핀부가 연직 하부에 위치하도록 해야만 된다.Therefore, before machining the crankshaft with a machine tool, the pin 1 of the crankshaft must be positioned below the vertical position using a phase setting device.

이러한 종래의 위상 설정 장치를 개략적으로 설명하면 다음과 같다.The conventional phase setting device will be briefly described as follows.

크랭크 축이 안치된 팔레트가 이송되는 컨베이어의 양측부에 한 쌍의 수직 실린더가 장착되어 있고, 각 수직 실린더의 상부에는 수평 실린더가 장착되어 있다. 또한, 각 수평 실린더에 크랭크 축의 위상 설정을 위한 구동원인 한 쌍의 모터가 연결되어 있고, 각 모터에 크랭크 축의 양단을 고정하는 한 쌍의 홀더가 설치되어 있다.A pair of vertical cylinders is mounted on both sides of the conveyor to which pallets on which crank shafts are placed are transported, and horizontal cylinders are mounted on top of each vertical cylinder. In addition, a pair of motors, which are driving sources for phase setting of the crankshaft, are connected to each horizontal cylinder, and a pair of holders for fixing both ends of the crankshaft are provided in each motor.

상기와 같이 구성되어서, 크랭크 축이 안치된 팔레트가 컨베이어를 타고 위상 설정 장치에 도착되면, 한 쌍의 수평 실린더에 의해 각 모터가 크랭크 축으로 전진하게 되어, 각 홀더가 크랭크 축의 양단을 지지하게 된다.When the pallet having the crankshaft settled on the conveyor reaches the phase setting device, the motor is advanced to the crankshaft by a pair of horizontal cylinders, and each holder supports both ends of the crankshaft. .

그러나, 크랭크 축이 팔레트에 안치된 상태에서는 크랭크 축을 회전시키는 것이 불가능하므로, 각 수직 실린더에 의해 수평 실린더와 모터가 상승하게 된다. 따라서, 크랭크 축은 모터와 함께 상승되는 홀더에 의해 지지된 상태로 팔레트에서소정 높이로 상승하게 된다.However, since it is impossible to rotate the crankshaft in a state where the crankshaft is placed on the pallet, the horizontal cylinder and the motor are lifted by each vertical cylinder. Thus, the crankshaft is raised to a predetermined height on the pallet while being supported by the holder which is lifted with the motor.

그런 다음, 모터의 구동으로 홀더가 회전되어, 크랭크 축의 1번 핀부가 수직선상의 하부에 위치하도록 위상을 설정시키게 된다.Then, the holder is rotated by the driving of the motor to set the phase so that the pin 1 of the crankshaft is located below the vertical line.

그러나, 상기된 종래의 크랭크 축 위상 설정 장치는, 크랭크 축을 회전시키는 구동원인 모터가 불필요하게 2개인 관계로, 장치의 가격이 비싸다는 단점이 있었다.However, the above-described conventional crankshaft phase setting device has a disadvantage in that the price of the device is expensive because unnecessary two motors, which are driving sources for rotating the crankshaft, are unnecessary.

따라서, 본 발명은 종래의 크랭크 축의 핀부 위상 설정 장치로 인해 야기되는 단점을 해소하기 위해 안출된 것으로서, 하나의 모터로 크랭크 축의 위상을 설정할 수 있도록 하는 크랭크 축의 핀부 위상 설정 장치를 제공하는데 목적이 있다.Accordingly, an object of the present invention is to provide a crankshaft pin phase setting device capable of setting a phase of a crankshaft with one motor, which is devised to solve the disadvantage caused by the conventional crankshaft pin phase setting device. .

상기와 같은 목적을 달성하기 위해 본 발명은, 크랭크 축이 안치된 팔레트가 이송되는 컨베이어의 양측부에 장착된 한 쌍의 수직 실린더; 상기 수직 실린더중 하나의 상부에 장착된 수평 실린더; 상기 수평 실린더에 연결되어, 수평 방향으로 전 후진되는 하나의 모터; 상기 모터에 연결되어, 크랭크 축의 일단을 고정시키는 고정 홀더; 및 상기 수직 실린더의 다른 하나의 상부에 장착되어, 크랭크 축의 타단을 회동가능하게 지지하는 지지 홀더를 포함하는 것을 특징으로 한다.In order to achieve the above object, the present invention, a pair of vertical cylinders mounted on both sides of the conveyor to which the pallet crank shaft is transferred; A horizontal cylinder mounted on top of one of the vertical cylinders; A motor connected to the horizontal cylinder and forward and backward in a horizontal direction; A fixed holder connected to the motor to fix one end of the crankshaft; And a support holder mounted on the other top of the vertical cylinder to rotatably support the other end of the crankshaft.

상기된 본 발명의 구성에 의하면, 하나의 모터로 회전되는 고정 홀더가 크랭크 축의 일단을 회전시키게 되고, 크랭크 축의 타단은 지지 홀더에 의해 단순히 회동가능하게 지지를 받게 되므로써, 모터가 하나만 구비되어도 되므로, 장치의 가격을 낮출 수가 있다.According to the configuration of the present invention described above, since the fixed holder rotated by one motor rotates one end of the crankshaft, and the other end of the crankshaft is simply rotatably supported by the support holder, only one motor may be provided. The price of the device can be lowered.

[실시예]EXAMPLE

이하, 본 발명의 바람직한 실시예를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 3은 본 발명에 따른 크랭크 축의 핀부 위상 설정 장치를 나타낸 것으로서, 도 1은 정면도, 도 2는 도 1에 대한 좌측면도, 도 3은 도 2에 대한 평면도이다.1 to 3 show a pin portion phase setting device of the crankshaft according to the present invention. FIG. 1 is a front view, FIG. 2 is a left side view of FIG. 1, and FIG. 3 is a plan view of FIG. 2.

참고로, 본 실시예의 구성을 설명함에 있어, 명세서의 서두에서 설명된 종래의 기술과 동일한 부분에 대해서는 설명의 중복을 피하기 위하여 반복설명은 생략하고 개선된 부분만을 주로하여 설명한다.For reference, in describing the configuration of the present embodiment, the same parts as in the prior art described at the beginning of the specification will be described mainly by omitting the repeated descriptions in order to avoid duplication of description.

도 1 내지 도 3에 도시된 바와 같이, 컨베이어(1)의 양측면에 한 쌍의 브래킷(11)이 설치되고, 각 브래킷(11)상에 한 쌍의 수직 실린더(21,22)가 설치된다. 각 수직 실린더(21,22)의 로드 상단에 한 쌍의 수평판(2,6)이 설치되는데, 특히 좌측의 수평판(2)에는 수평 실린더(3)가 장착된다. 한편, 우측 수평판(6)에는 크랭크 축의 우측 단부를 회동가능하게 지지하는 지지 홀더(7)가 설치된다.1 to 3, a pair of brackets 11 are installed on both sides of the conveyor 1, and a pair of vertical cylinders 21 and 22 are installed on each bracket 11. A pair of horizontal plates 2 and 6 are installed on the rod tops of the vertical cylinders 21 and 22, and in particular, the horizontal cylinders 3 are mounted to the horizontal plates 2 on the left side. On the other hand, the right horizontal plate 6 is provided with a support holder 7 for rotatably supporting the right end of the crankshaft.

수평 실린더(3)의 로드에는 다른 하나의 수평판(5)이 장착되고, 이 수평판 (5)상에 크랭크 축의 핀부 위상을 설정하는 구동원인 하나의 모터(4)가 장착된다. 즉, 본 발명에서는 모터가 종래와는 달리 2개가 아니라 하나만 구비된다. 한편, 모터(4)에는 크랭크 축의 좌측 단부를 고정하여, 그 제 1 핀부가 수직선상 하부에 정확히 위치되도록 크랭크 축을 회전시키는 고정 홀더(8)가 설치된다.The other horizontal plate 5 is mounted on the rod of the horizontal cylinder 3, and on this horizontal plate 5 is mounted one motor 4 which is a drive source for setting the phase of the pin portion of the crankshaft. That is, in the present invention, unlike the prior art, only one motor is provided, not two. On the other hand, the motor 4 is provided with a fixing holder 8 which fixes the left end of the crankshaft and rotates the crankshaft so that the first pin portion is located exactly below the vertical line.

이하, 상기와 같이 구성된 본 실시예의 동작을 상세히 설명한다.Hereinafter, the operation of this embodiment configured as described above will be described in detail.

크랭크 축이 안치된 팔레트가 컨베이어(1)상을 따라 이송되다가 위상 설정장치에 도착하면, 수평 실린더(3)가 전진되어, 수평판(5)과 모터(4)도 같이 크랭크 축이 위치한 방향으로 전진하게 된다. 크랭크 축은 그 좌측 단부가 고정 홀더(8)에 고정되면서 뒤로 밀리다가, 그 우측 단부가 지지 홀더(7)에 회동가능하게 끼워진다.When the pallet with the crank shaft settles along the conveyor 1 and arrives at the phase setting device, the horizontal cylinder 3 is advanced, so that the horizontal plate 5 and the motor 4 are located in the same direction as the crank shaft. Go forward. The crankshaft is pushed back with its left end fixed to the fixed holder 8, and the right end thereof is pivotably fitted to the support holder 7.

이러한 상태에서, 각 수직 실린더(21,22)가 구동되어, 양 수평판(2,6)을 상승시킨다. 따라서, 크랭크 축은 팔레트에서 소정 높이로 상승하게 된다. 그리고, 모터(4)가 구동되어, 고정 홀더(8)가 크랭크 축의 좌측 단부를 회전시키게 되므로써, 크랭크축의 제 1 핀부가 수직선상 하부에 정확히 위치되어진다.In this state, each of the vertical cylinders 21 and 22 is driven to raise both horizontal plates 2 and 6. Thus, the crankshaft rises to a predetermined height in the pallet. Then, the motor 4 is driven so that the fixed holder 8 rotates the left end of the crankshaft so that the first pin portion of the crankshaft is accurately positioned below the vertical line.

이와 같이, 크랭크 축의 제 1 핀부가 수직선상 하부에 위치하게 되면, 공작기계에서 크랭크 축을 가공할 수가 있게 된다.In this way, when the first pin portion of the crankshaft is positioned below the vertical line, the crankshaft can be machined by the machine tool.

상기된 바와 같이 본 발명에 의하면, 하나의 모터(4)로 크랭크 축의 핀부 위상을 설정할 수가 있게 되므로써, 종래의 장치에서 모터 하나를 삭제할 수가 있게 되어, 그만큼 장치의 가격이 낮아지게 된다.According to the present invention as described above, since the pin phase of the crankshaft can be set by one motor 4, one motor can be deleted from the conventional apparatus, and the price of the apparatus is lowered accordingly.

한편, 본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.On the other hand, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. will be.
