Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to an air tightness detection device for a hydraulic pump. Background Art

[0002] The air tightness test of hydraulic pumps is an important step to ensure their normal operation and prevent leakage. This usually involves using pressure testing equipment, placing the hydraulic pump under a certain pressure, inflating the hydraulic pump inlet, plugging the outlet, placing it in water, and observing whether there is gas leakage.

[0003] After the air tightness test of the hydraulic pump is completed, moisture will adhere to its surface to increase the intensity of subsequent processing.

[0004] In order to solve the above problems, the present application proposes a hydraulic pump air tightness detection device. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes a hydraulic pump air tightness detection device. The utility model is provided with a rotating mechanism so that after the detection is completed, the hydraulic pump is rotated to increase the dryness of the outside of the hydraulic pump and reduce the tediousness of subsequent processing.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the utility model provides a hydraulic pump air tightness detection device, comprising a detection pool and a hydraulic pump, wherein a mounting plate is fixedly mounted on one side of the top of the detection pool;

[0009] A top plate is fixedly mounted on the mounting plate, and a rodless cylinder is fixedly mounted on the mounting plate;

[0010] A placement plate is fixedly mounted on the movable table of the rodless cylinder, and a rotating mechanism which rotates when the placement plate moves back is provided on the placement plate, and the rotating mechanism is used to throw water out of the hydraulic pump;

[0011] The hydraulic pump is placed on the rotating mechanism.

[0012] Preferably, the rotating mechanism includes a turntable, a driving disk and a spiral blade. The turntable and the driving disk are both rotatably sleeved on the placement plate and transmit power to each other. A rectangular opening for the spiral blade to pass through is opened in the middle of the driving disk. One end of the spiral blade is fixedly connected to the top plate. The hydraulic pump is placed on the turntable.

[0013] Preferably, the outer circumferences of the driving disk and the rotating disk are fixedly sleeved with mutually meshing gear rings, and the gear rings are rotatably sleeved with the placement plate.

[0014] Preferably, a ball bearing which is rollingly connected to the bottom of the gear ring is rotatably sleeved inside the placement plate.

[0016] The above technical solution of the utility model has the following beneficial technical effects:

[0017] The rodless cylinder can drive the placement plate into the interior of the detection pool for sealing detection. The rodless cylinder drives the placement plate to move back, and the spiral blade passes through the rectangular opening in the middle of the driving disk. Since the position of the spiral blade remains unchanged, the driving disk continues to move up along the spiral blade, and the driving disk rotates. The driving disk drives the turntable to rotate, so that the hydraulic pump rotates, increasing the phenomenon of liquid water detachment on its surface, thereby reducing the liquid water on the hydraulic pump and increasing the convenience of subsequent processing.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] like Figure 1-2 As shown, the utility model provides a hydraulic pump air tightness detection device, comprising a detection pool 1 and a hydraulic pump 7, wherein a mounting plate 2 is fixedly mounted on one side of the top of the detection pool 1;

[0023] A top plate 3 is fixedly mounted on the mounting plate 2, and a rodless cylinder 4 is fixedly mounted on the mounting plate 2;

[0024] A placing plate 5 is fixedly mounted on the movable platform of the rodless cylinder 4, and a rotating mechanism 6 is provided on the placing plate 5 which is rotated by the return movement of the placing plate 5, and the rotating mechanism 6 is used to throw water out of the hydraulic pump;

[0025] The hydraulic pump 7 is placed on the rotating mechanism 6 .

[0026] In an optional embodiment, the rotating mechanism 6 includes a turntable 61, a driving disk 62 and a spiral blade 63. The turntable 61 and the driving disk 62 are both rotatably sleeved on the placement plate 5 and transmit power to each other. A rectangular opening for the spiral blade 63 to pass through is opened in the middle of the driving disk 62. One end of the spiral blade 63 is fixedly connected to the top plate 3. The hydraulic pump 7 is placed on the turntable 61.

[0027] The outer circumferences of the driving disc 62 and the rotating disc 61 are both fixedly sleeved with mutually meshing gear rings 64 , and the gear rings 64 are rotatably sleeved with the placement plate 5 .

[0028] Under the action of the gear ring 64, the stability of the transmission is increased.

[0029] Furthermore, a ball 65 which is rollingly connected to the bottom of the gear ring 64 is rotatably sleeved inside the placement plate 5 .

[0030] It should be noted that, under the action of the ball 65, the smoothness of the rotation is increased.
