Description

  The present invention provides a pump comprising: a drive motor; a rotary shaft that is rotated by the drive motor; a rod that converts the rotation of the rotary shaft into a reciprocating motion in an orthogonal direction; and a pump body connected to the rod. The present invention relates to a pump mounting base to be mounted.

  In various pumps, there is provided a pump including a drive motor, a rotary shaft that is rotated by the drive motor, a rod that converts the rotation of the rotary shaft into a reciprocating motion in an orthogonal direction, and a pump body connected to the rod. Are known. This pump has a special arrangement in which the axis of the drive motor and the pump main body intersect, and a pump mounting base having sufficient structural strength against the load and vibration of the pump main body is required.

  Therefore, conventionally, the pump mounting base is often manufactured by casting. The pump mounting base manufactured by casting has the advantage that it is structurally strong enough and suitable for mass production once the mold is manufactured.

  However, in recent years, the pump industry has not only manufactured a large number of pumps of the same type, but also has focused on manufacturing only a small amount of different types of pumps according to customer requirements. In this way, when the pump mounting base is manufactured by casting under the manufacture of a small variety of products, it is necessary to manufacture a mold to manufacture a small amount of pump, or a different mold for each type of pump. The production cost of the pump has increased because it has to be manufactured.

  Therefore, it is conceivable to manufacture the pump mounting base with sheet metal instead of casting. As shown in Non-Patent Document 1, there is actually a pump mounting base manufactured with sheet metal for a small pump.

IBS Co., Ltd., “Pump Diaphragm Pump Diaphragm Air Pump LVM-10 / MF-1”, [online], IBS Co., Ltd. [Search April 10, 2015], Internet <http: //www.ask- ibs.jp/goods/?id=1414387368-913165&p=1&sca=1412059229-915109>

  However, when the pump mounting base is made of sheet metal with the same structure as that of a casting, there is a problem that the strength is not sufficient structurally compared to the casting. For this reason, the pump mounting base made of sheet metal can be applied to a small pump with relatively small load and vibration of the pump body as described above, but the medium or large pump with relatively large load and vibration of the pump body. It was difficult to apply.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a pump mounting base having structurally sufficient strength against the load and vibration of the pump body while being manufactured by sheet metal. To do.

  In order to achieve the above-mentioned object, the present invention is connected to a drive motor, a rotary shaft that is rotated by the drive motor, a rod that converts the rotation of the rotary shaft into a reciprocating motion in an orthogonal direction, and the rod.

The rotating shaft protruding from the rotating shaft opening and the rod protruding from the rod opening are disposed in a space below the second top plate.

  According to this, since the first support body formed of the first sheet metal and the second support body formed of the second sheet metal are joined together to form one pump mounting base, It is possible to structurally increase the strength against the load and vibration of the pump body placed on the first top plate portion and the second top plate portion. And since the rotating shaft of a drive motor and the rod of a pump main body are arrange | positioned in the space under the said 2nd top-plate part, it can operate | move stably, maintaining safety.

  The first support is provided with a first bottom plate at the lower end of the first support plate, and the second support is provided with a second bottom plate at the lower end of the second support plate. Preferably, a part is provided. According to this, the pump mounting base can be stably fixed to the base or the like.

  The first support is formed in a U shape by the first top plate, the first support plate, and the first bottom plate, and the second support is the second top plate. It is preferable that a U-shape is formed by the portion, the second support plate portion, and the second bottom plate portion. According to this, the 1st support body and the 2nd support body can be easily formed with sheet metal.

  In this case, the first support body and the second support body may be joined in a state where the first support plate portion and the second support plate portion face each other while being separated from each other. Alternatively, the first support plate portion and the second support plate portion are joined in a state of being in opposite directions while being in contact with each other, and the second rotation shaft opening portion through which the rotation shaft is inserted. May be formed. According to this, the first support body and the second support body can be easily joined while structurally increasing the strength.

  In addition, it is preferable that the first top plate portion is provided with an upper fixed plate portion extending downward, and a peripheral surface of the drive motor is in contact with the upper fixed plate portion. According to this, since the peripheral surface of the drive motor is in contact with the upper fixed plate portion, the drive motor can be stably fixed.

  Further, it is preferable that the first bottom plate portion is provided with a lower fixing plate portion extending upward, and a peripheral surface of the drive motor is in contact with the lower fixing plate portion. According to this, since the peripheral surface of the drive motor is in contact with the lower fixing plate portion, the drive motor can be stably fixed.

  Moreover, it is preferable that the said 2nd top plate part has the said opening part for rods formed in the edge part by the side of the said 1st support plate part. According to this, the length that the rotating shaft protrudes from the rotating shaft opening is shortened, and the moment acting on the rotating shaft during operation is reduced, so that the rotating shaft and rod of the pump can operate stably. it can.

  According to the present invention, the first support formed by the first sheet metal and the second support formed by the second sheet metal are joined together to form one pump mounting base. It is possible to structurally increase the strength against the load and vibration of the pump body placed on the first top plate portion and the second top plate portion.

  And since the rotating shaft of a drive motor and the rod of a pump main body are arrange | positioned in the space under the said 2nd top-plate part, it can operate | move stably, maintaining safety.

  Therefore, although it is a sheet metal having a simple configuration, it can structurally increase the strength and can operate stably while maintaining safety, so it can be widely applied to various pumps from small to large. . For this reason, since the pump mounting base can be manufactured inexpensively and speedily, it is possible to supply a wide variety and a small amount of pumps according to customer requirements.
