DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Please refer to Figures 1-4

[0025] Embodiment 1: A motor airtightness detection device, including an airtight detection box body 1, an airtight input control bottom box 2 is arranged at the bottom of the airtight detection box body 1, an operation panel 3 is arranged on the side of the airtight input control bottom box 2, an operation connection plate 4 is installed at the top of the side of the airtight detection box body 1, and a plurality of pressure sensors 5 are arranged on the operation connection plate 4.

[0026] A touch screen 6 is installed in the middle of the operation connection plate 4. A two-color light 7 is arranged on the side of the pressure sensor 5. A driving cylinder 8 is installed in the middle of the top of the airtight detection box body 1. Limiting connecting rods 9 are evenly arranged around the inside of the airtight detection box body 1. A driving connection plate 10 is also arranged inside the airtight detection box body 1. Limiting sleeves 11 are arranged around the driving connection plate 10. The limiting connecting rods 9 all pass through the limiting sleeves 11.

[0027] A bottom mounting frame 12 is arranged at the bottom of the driving connection plate 10. Three air injection nozzles 13 are arranged on the bottom mounting frame 12. The driving end at the bottom of the driving cylinder 8 penetrates through the top of the airtight detection box body 1 and is connected to the top end of the driving connection plate 10 through a set push connecting rod 14. An electromagnetic valve 15 is arranged at the top of the airtight detection box body 1. A pressure regulating valve 16 is arranged on the side of the electromagnetic valve 15.

[0028] A motor carrier plate 17 is arranged at the bottom of the bin of the airtight detection box body 1. Two side positioning holes 18 are symmetrically opened on the left and right sides of the motor carrier plate 17. Three motor fixing carriers 19 are evenly arranged at the top of the motor carrier plate 17. A motor main body 20 is clamped on the motor fixing carriers 19. Connection handles 21 are symmetrically arranged on the left and right sides of the motor carrier plate 17. A power supply interface 22 is arranged at the rear side of the airtight input control bottom box 2. A total air inlet 23 is arranged on the side of the power supply interface 22.

[0029] Embodiment 2: The difference between this embodiment and Embodiment 1 is that two handles are symmetrically arranged on the left and right sides of the airtight input control bottom box 2.

[0030] This makes it more convenient for users to move the device.

[0031] Embodiment 3: The difference between this embodiment and Embodiment 1 is that a hose is arranged to connect the air injection nozzle 13 and the pressure regulating valve 16.

[0032] This enables the detection gas entering the pressure regulating valve 16 to enter the air injection nozzle 13 through the hose.

[0033] Embodiment 4: The difference between this embodiment and Embodiment 1 is that the air injection nozzle 13 is directly above the air injection port at the top of the motor main body 20.

[0034] This makes the air injection into the motor main body 20 by the air injection nozzle 13 more accurate and convenient.

[0035] In this embodiment, since the existing airtightness detection device for motors can only detect motors with ordinary square specifications, it is difficult to effectively fix and detect motors with some shape characteristics. Moreover, when the common airtightness detection probe is inserted into the gap for detection, the gas input is slow, and it is difficult to fill the inside of the motor in a short time, which will greatly prolong the airtightness detection time of the motor, with low work efficiency and high error rate, and it is difficult to meet the user's requirement for rapid detection of the motor.

[0036] In summary, during specific implementation, when the user needs to perform airtightness detection on the motor body 20, the user first needs to clamp the motor body 20 on the motor fixing carrier 19. The motor fixing carrier 19 is provided with a special slot corresponding to the motor body 20, so that the motor body 20 can be quickly and conveniently fixed on the motor fixing carrier 19. In order to make the position fixing between each motor fixing carrier 19 more accurate, two side positioning holes 18 are also provided on the left and right sides of the motor carrier plate 17. Through the positioning function of the side positioning holes 18, the position of the motor body 20 installed in the motor fixing carrier 19 can be made more accurate.

[0037] Then, the user presses the start switch set on the operation panel 3 to start the driving cylinder 8 installed on the top of the airtightness detection box 1, so that the driving cylinder 8 can drive the bottom mounting frame 12 by pushing the connecting rod 14. And the bottom mounting frame 12 is connected to the driving connecting plate 10, and the periphery of the driving connecting plate 10 is provided with limiting sleeves 11. The limiting sleeves 11 are all limited and penetrated by the limiting connecting rods 9 arranged in the warehouse of the airtightness detection box 1. Thus, the pushing of the driving cylinder 8 on the bottom mounting frame 12 can only be on the vertical line up and down, which can ensure that the gas injection pipe head 13 installed at the bottom of the bottom mounting frame 12 moves straight down, so that the gas injection pipe head 13 can be inserted into the air inlet of the top of the motor body 20.

[0038] And the gas required for detection is externally connected to the device through the total air inlet 23 provided on the side of the airtight input control bottom box 2, and is sequentially transported to the gas injection pipe head 13 through the pressure regulating valve 16 and the connected hose, and is injected into the motor body 20 through the gas injection pipe head 13. Thus, the inside of the motor body 20 can be quickly and conveniently filled with the detection gas, greatly improving the airtightness detection efficiency of the motor body 20 by the user, effectively improving the work efficiency, and having a relatively low error rate, which can meet the user's requirement for rapid airtightness detection of the motor body 20 and facilitate the user's use.
