Detailed Description
In order to make the purpose and technical solution of the present invention clearer, the following description is made with reference to the accompanying drawings and embodiments to further explain the present invention:
the device for testing the new energy motor shell comprises a testing bin 1, a water storage bin 2, a hydraulic sealing machine 3, an air inlet pipe 4, an air outlet pipe 5 and an inflator pump 6, and is shown in figures 1-5.
The hydraulic sealing machine 3 is provided with a base 31, a lower sealing silica gel pad 32, an upper sealing silica gel pad 33, a hydraulic plate 34, a hydraulic rod 35 and an air duct 36; the hydraulic sealing machine 3 is fixed in the test bin 1 by the base 31 through bolts, the lower sealing silica gel pad 32 is installed on the base 31, and the hydraulic plate 34 is provided with an air guide hole 341 for fixedly installing an air guide pipe 36; the upper sealing silica gel pad 33 is provided with an air inlet 331 at a position corresponding to the air-guiding hole 341 of the hydraulic plate 34.
The testing bin 1 is positioned above the water storage bin 2, and the bottom of the testing bin is provided with a water inlet 11 communicated with the water storage bin 2; the water storage bin 2 is a cavity with the periphery sealed, the bottom is provided with an air inlet 21 and an air outlet 22, and the side is provided with an air inlet pipe 4 and a water outlet pipe 5; the air inlet pipe 4 is communicated with the air inlet hole 21 through an air inlet valve 42; the water discharge pipe 5 is communicated with the air discharge hole 22 through an air discharge valve 43; the intake valve 42 and the exhaust valve 43 are both higher than the water inlet 11.
The air guide valve 41 is positioned above the air inlet valve 42 and is communicated with the air guide pipe 36; the intake pipe 4 of the air guide valve 41 and the intake valve 42 is connected to the inflator 6.
The detection steps are as follows:
firstly, water is poured into the test bin 1 and flows into the water storage bin 2 through the water inlet 11 until the water storage bin 2 is filled.
Secondly, as shown in fig. 4, a shell (outer shell or inner shell) of the new energy motor to be detected is placed on the lower sealing silica gel pad 32 on the base 31, so that the lower sealing silica gel pad 32 covers one end of the outer shell or the inner shell; the upper sealing silicone pad 33 covers the other end of the housing and is rotated to adjust the air inlet 331 so that it is located directly below the air vent 341 of the hydraulic plate 34.
