회전체 레벨 조정용 다이구조체{die structure for controlling impeller level}Die structure for controlling impeller level

본 발명은 회전체 레벨 조정용 다이구조체에 관한 것으로서, 더 상세하게는 샤프트가 결합되는 축공을 갖는 회전체를 간편하게 높이 및 수평 조절이 가능하도록 하여 수직으로 매달린 샤프트가 축공에 결합될때 축공의 내경 또는 샤프트의 외경에 손상을 최소화시키면서 간편하고 정확하게 결합시킬 수 있도록 한 회전체 레벨 조정용 다이구조체에 관한 것이다. The present invention relates to a die structure for rotating body level adjustment, and more particularly, it is possible to easily adjust the height and horizontal rotation of the rotating body having a shaft hole to which the shaft is coupled to the inner diameter or shaft of the shaft hole when the vertically suspended shaft is coupled to the shaft hole The present invention relates to a die structure for rotating body level adjustment, which allows easy and accurate coupling with minimal damage to the outer diameter of the engine.

예컨대, 기화용 해수펌프의 정비 또는 점검을 위해 샤프트와 임펠러를 분해한 후, 다시 샤프트를 임펠러의 축공에 결합시킬때 약 10/100mm의 공차 이내로 정밀한 끼워 맞춤이 이루어져야 한다.For example, after disassembling the shaft and the impeller for maintenance or inspection of the seawater pump for vaporization, precise fitting must be made within a tolerance of about 10/100 mm when the shaft is coupled to the shaft hole of the impeller.

이때 다이(Die)에 놓여진 임펠러의 레벨이 맞지 않은 상태에서 무리한 조립을 하게 되면, 크레인에 매달려 있는 샤프트의 외경 또는 임펠러의 내경에 스크래치 등의 흠집이 발생하게 된다.At this time, if the level of the impeller placed on the die (Die) is not excessively assembled, scratches such as scratches are generated on the outer diameter of the shaft hanging on the crane or the inner diameter of the impeller.

따라서 작업현장 바닥의 평탄도 등이 임펠러와 샤프트의 조립 정밀도를 좌우하게 되며, 다이의 레벨을 맞추기 위하여 침목 등의 별도 도구가 요구되고 레벨링 작업시간에 따른 조립시간이 과다 소요되게 된다.Therefore, the flatness of the floor of the work site determines the assembly precision of the impeller and the shaft. In order to adjust the level of the die, a separate tool such as a sleeper is required and the assembly time according to the leveling work time is excessive.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 임펠러와 같은 회전체가 탑재되는 다이의 레벨링작업을 간편하게 하고 조립시간을 단축시킬 수 있도록 한 회전체 레벨 조정용 다이구조체를 제공하는 데 그 목적이 있다.The present invention was created to solve the above problems, to provide a die structure for rotating body level adjustment to simplify the leveling operation of the die on which the rotating body such as an impeller is mounted and to reduce the assembly time. There is this.

상기 상부프레임 또는 수직프레임에 부착되어 상기 회전체의 수평상태를 표시하는 복수의 레벨을 구비하여 된 것을 특징으로 한다.And a plurality of levels attached to the upper frame or the vertical frame to indicate a horizontal state of the rotating body.

또한, 본 발명 다이구조체는 상기 수직프레임에 복수의 이동용 캐스터가 더 구비된 것을 특징으로 한다.In addition, the die structure of the present invention is characterized in that the plurality of movable casters are further provided in the vertical frame.

본 발명 회전체 레벨 조정용 다이구조체는 회전체의 수평상태를 표시하는 복수의 레벨 및 높이 조절을 가능하게 하는 복수의 높이조절용 볼트를 구비함으로써, 회전체의 수평상태를 간편하고 정확하게 조절하여 샤프트의 조립정밀도를 높일 수 있게 한다.The present invention has a die structure for adjusting the level of the rotating body having a plurality of height adjusting bolts that enable the level and height adjustment for displaying the horizontal state of the rotating body, thereby easily and accurately adjusting the horizontal state of the rotating body to assemble the shaft. It allows you to increase the precision.

또한, 복수의 캐스터를 구비함으로써 중량의 다이구조체를 간편하게 이동시킬 수 있게 한다.In addition, by providing a plurality of casters, it is possible to easily move the weight die structure.

본 발명 실시예의 회전체 레벨 조정용 다이구조체는 예컨대, 기화용 해수펌프의 정비 또는 점검을 위해 샤프트와 임펠러를 분해한 후, 다시 샤프트를 임펠러의 축공에 결합시킬때 임펠러의 수평상태를 조절하여 샤프트와의 조립정밀도를 높일 수 있도록 한다.The die structure for rotating body level adjustment according to the embodiment of the present invention, for example, disassembles the shaft and the impeller for maintenance or inspection of the seawater pump for vaporization, and then adjusts the horizontal state of the impeller when the shaft is coupled to the shaft hole of the impeller. To increase the assembly accuracy.

본 발명 실시예의 다이구조체를 나타낸 도 1을 참조하면, 이는 상기 임펠러(회전체;20)가 안착되는 상부프레임(31)과, 상기 상부프레임(31)을 일정 높이로 유지시키는 복수의 수직프레임(32)과, 상기 각 수직프레임(32)의 하단부에 결합되어 상부프레임(31)의 높이조절을 가능하게 하는 높이조절용 볼트(33)와, 상기 상부프레임(31) 또는 수직프레임(32)에 부착되어 상기 임펠러(20)의 수평상태를 표시하는 복수의 레벨(34)을 구비한다.Referring to Figure 1 showing a die structure of the embodiment of the present invention, it is an upper frame 31, the impeller (rotator; 20) is seated, and a plurality of vertical frames (maintaining the upper frame 31 at a constant height ( 32, a height adjusting bolt 33 coupled to the lower end of each vertical frame 32 to enable height adjustment of the upper frame 31, and attached to the upper frame 31 or the vertical frame 32. And a plurality of levels 34 to indicate the horizontal state of the impeller 20.
