일반적으로 2차 펌프의 정비시 부품교체 작업을 위하여 디퓨저 하우징(diffuser housing)에 삽입된 부싱(bushing)을 취외시키기 위하여는, 중량의 디퓨져 하우징을 펌프 본체로부터 분리시킨 후 유압프레스를 이용하여 운반시킨 후 수동 툴(tool)을 사용하여 취외시키고 있다.In general, in order to remove the bushing inserted into the diffuser housing for the replacement of parts during the maintenance of the secondary pump, the diffuser housing is separated from the pump body and transported using a hydraulic press. It is then left out using a manual tool.

이와 같은 일반적인 취외장치는 중량의 하우징을 운반시키기 번거롭고 작업시간이 많이 소요되는 문제점이 있다.Such a general extraction apparatus has a problem in that it is cumbersome to carry a heavy housing and takes a long time.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 중량의 하우징을 펌프 본체로부터 분리시키지 아니하고도 부싱을 간편하게 취외시킬 수 있도록 한 펌프 하우징의 부싱 취외장치를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a bushing take-out device of the pump housing that can easily take out the bushing without separating the weight of the housing from the pump body.

상기 목적을 달성하는 본 고안은 하우징의 중심공에 결합된 부싱을 취외시키기 위한 펌프 하우징의 부싱 취외장치에 있어서,The present invention to achieve the above object in the bushing take-out device of the pump housing for taking out the bushing coupled to the central hole of the housing,

상기 부싱의 내주면에는 복수의 진입홈이 형성되고,A plurality of entry grooves are formed on the inner circumferential surface of the bushing,

유압 또는 공압을 발생시키며 출몰되는 로드를 가지는 실린더와,A cylinder having a rod, which is hydraulically or pneumatically generated,

일단이 상기 실린더 몸체 선단에 결합되고 타단이 상기 부싱을 포위하도록 상기 하우징에 지지되며 상기 로드가 출입되는 통형의 지지통과,A cylindrical support tube having one end coupled to the cylinder body end and the other end supported by the housing so as to surround the bushing, and the rod being moved in and out;

상기 로드의 단부에 결합되며 그 외주면에 상기 진입홈에 진입 및 진출이 가능한 견인돌기가 형성된 풀러를 구비하여서,A puller coupled to an end of the rod and having a tow protrusion formed at an outer circumference thereof to allow entry and exit of the entry groove;

상기 풀러의 견인돌기가 상기 부싱의 진입홈을 통하여 진입된 후, 상기 견인돌기가 진입홈으로부터 벗어나도록 회전시키고, 상기 실린더의 가동으로 풀러의 견인돌기가 부싱을 견인하여 상기 하우징으로부터 취외시키도록 된 것을 특징으로 한다.After the puller projection of the puller enters through the entry groove of the bushing, the towing projection rotates to be out of the entry groove, and the puller of the puller pulls the bushing out of the housing by the operation of the cylinder. It is characterized by.

또한, 본 고안 장치는 상기 로드의 단부에 상기 풀러의 이탈을 방지시키는 마감캡이 더 결합된 것을 특징으로 한다.In addition, the device of the present invention is characterized in that the end cap of the rod is further coupled to prevent separation of the puller.

본 고안 취외장치는 부싱에 진입홈을 형성시키고, 견인돌기를 가지는 풀러를 실린더에 장착하여서, 실린더를 가동시킬 때 풀러의 견인력과 지지통의 반력에 의해서 부싱을 간편하게 취외시킬 수 있게 한다.The devising apparatus of the present invention forms an access groove in the bushing, and attaches a puller having a towing protrusion to the cylinder, so that the bushing can be easily removed by the puller's traction force and the reaction force of the support cylinder when the cylinder is operated.

이러한 본 고안은 하우징을 펌프 본체로부터 분리시키지 않고도 간단하게 부싱을 취외시킬 수 있게 한다.This invention allows the bushing to be removed simply without removing the housing from the pump body.

본 고안 실시예의 취외장치는 펌프의 디퓨져 하우징(diffuser housing)에 삽입되어 있는 부싱(bushing)을 간편하게 취외시킬 수 있도록 한다.The extraction apparatus of the embodiment of the present invention allows the bushing inserted in the diffuser housing of the pump to be easily removed.

이 취외장치는 도 1a, 도 2 및 도 3을 참조하면, 디퓨져 하우징(20)의 중심구멍에는 환형의 부싱(21)이 결합되며, 부싱(21)의 내주면에는 복수의 진입홈(21a)이 형성되어 있다.1A, 2, and 3, the outflow apparatus includes an annular bushing 21 coupled to a central hole of the diffuser housing 20, and a plurality of entry grooves 21a formed on an inner circumferential surface of the bushing 21. Formed.

이 실시예의 장치는 상기 부싱(21)을 유압 또는 공압으로 작동되는 실린더(10)의 가동압으로 취외시킨다.The device of this embodiment draws out the bushing 21 at the movable pressure of the cylinder 10 which is operated hydraulically or pneumatically.

실린더(10)의 몸체 선단에는 통형의 지지통(50)이 결합되며, 이 지지통(50)의 단부는 상기 부싱(21)을 포위하도록 상기 하우징(20)에 지지된다.A cylindrical support cylinder 50 is coupled to the front end of the cylinder 10, and an end of the support cylinder 50 is supported by the housing 20 to surround the bushing 21.

상기 실린더(10)의 로드(11)는 상기 지지통(50) 내부로 출몰가능하게 된다.The rod 11 of the cylinder 10 becomes wanderable into the support cylinder 50.

실린더(10)의 로드(11)에는 풀러(puller;30)가 결합된다. 풀러(30)의 외주면에는 상기 부싱(21)의 진입홈(21a)을 따라 진입될 수 있는 견인돌기(31)가 형성되어 있다.A puller 30 is coupled to the rod 11 of the cylinder 10. At the outer circumferential surface of the puller 30 is formed a traction projection 31 that can be entered along the access groove (21a) of the bushing (21).

또한, 로드(11)의 단부에는 상기 풀러(30)의 이탈을 방지시키는 마감캡(40)이 더 결합된다. In addition, the end of the rod 11 is further coupled to the closing cap 40 to prevent the puller 30 is separated.

상기와 같은 구성을 가지는 본 고안 실시예의 취외장치는 다음과 같이 작동된다. The extraction apparatus of the present invention having the configuration as described above is operated as follows.

먼저, 도 1a에서와 같이, 상기 부싱(21)을 포위하도록 지지통(50)을 하우징(20)에 지지시킨다. 이때 풀러(30)의 견인돌기(31)가 부싱(21)의 진입홈(21a)과 일치되도록 위치시킨다.First, as shown in FIG. 1A, the support cylinder 50 is supported on the housing 20 to surround the bushing 21. At this time, the pull projection (31) of the puller (30) is positioned so as to match the entry groove (21a) of the bushing (21).

이어서 도 1b에서와 같이, 실린더(10)를 가동하여 풀러(30)를 하강시켜서 부싱(21)을 관통시킨다. 이때 풀러(30)의 견인돌기(31)가 부싱(21)의 진입홈(21a)을 통과하게 된다.Subsequently, as shown in FIG. 1B, the cylinder 10 is operated to lower the puller 30 to penetrate the bushing 21. At this time, the pull projection 31 of the puller 30 passes through the entry groove 21a of the bushing 21.

이어서 도 1c에서와 같이, 실린더(10), 지지통(50) 및 풀러(30)를 일정각도 회전시켜서, 진입홈(21a)위치로부터 견인돌기(31)가 벗어나도록 한다.Subsequently, as shown in FIG. 1C, the cylinder 10, the support cylinder 50, and the puller 30 are rotated at an angle so that the tow protrusion 31 is deviated from the position of the entry groove 21a.

이와 같은 상태에서, 도 1d에서와 같이, 실린더(10)를 가동하여 풀러(30)가 상방향으로 이동될 때 부싱(21)이 견인되면서 하우징(20)으로부터 취외되게 된다.In this state, as in FIG. 1D, when the puller 30 moves upward by moving the cylinder 10, the bushing 21 is pulled out of the housing 20.

이때 풀러(30)에 의한 부싱(21)의 견인력은 하우징(20)에 지지된 지지통(50)의 반력에 의해서 안정적으로 제공되게 된다.At this time, the pull force of the bushing 21 by the puller 30 is stably provided by the reaction force of the support cylinder 50 supported by the housing 20.

상기와 같은 본 고안 취외장치는 부싱(21)에 진입홈(21a)을 형성시키고, 견인돌기(31)를 가지는 풀러(30)를 실린더(10)에 장착하여서, 실린더(10)를 가동시킬 때 풀러(30)의 견인력과 지지통(50)의 반력에 의해서 부싱(21)을 간편하게 취외시킬 수 있게 한다.The above-described devise taking out device forms an entry groove 21a in the bushing 21 and mounts the puller 30 having the towing protrusion 31 to the cylinder 10 to operate the cylinder 10. By the pulling force of the puller 30 and the reaction force of the support cylinder 50, the bushing 21 can be easily taken out.

이러한 본 고안 장치는 하우징(20)을 펌프 본체로부터 분리시키지 않고도 간단하게 부싱(21)을 취외시킬 수 있게 한다.This inventive device allows the bushing 21 to be taken out simply without removing the housing 20 from the pump body.

도 1a 내지 도 1d는 본 고안 장치의 작동상태도,1a to 1d is an operating state of the device of the present invention,

도 2는 부싱이 결합된 하우징의 평면도,2 is a plan view of a housing in which a bushing is coupled;

도 3은 풀러를 나타낸 사시도이다.3 is a perspective view of the puller.
