Contents of the invention

The technical problem to be solved by the utility model is to provide a motor air tightness inspection device with simple structure, reasonable design, safe and reliable use.

In order to solve the above technical problems, the technical solution adopted by the utility model is: the motor air tightness inspection device includes a lower mold base plate, and the lower mold base plate is provided with a stator neutral module, a rear stator fixing plate and a quick clamp Head A, the stator neutral module and the left fixed plate are connected with the rubber gasket A by screws, the rubber gasket A acts as a seal between the stator neutral module and the left fixed plate, and the left fixed plate is provided with pipe threads The hole is convenient to install the PC thread straight through to connect the air pipe; the quick chuck B is connected to the stator seal sleeve through threads, and the stator seal sleeve is provided with threads, and the height of the stator seal sleeve can be adjusted by rotating the thread to achieve sealing performance; The quick chuck A is fixed by threaded connection with the stator, and the front and rear distance of the chuck is adjusted by the left and right swing of the upper handle of the quick chuck A so that the motor plays a positioning role.

When in use, put the notch of the three-phase line of the motor after installation into the tooling corresponding to the notch of the left fixing plate on the airtight device, and push the upper handle of the quick chuck A to make the stator fixed chuck press the motor , after pushing the quick joint B handle to make the stator sealing sleeve press the upper part of the motor, so that the motor is fixed on the inspection device, open the air pipe valve and adjust the pressure through the pressure regulating valve, and then close the valve to see if the pointer on the pressure gauge drops. If the pointer does not change, the product is qualified.

A further improvement is that the stator sealing sleeve and the stator fixing clip are respectively movably connected with the quick chuck through threads; the stator sealing sleeve and the stator fixing clip can adjust the moving distance through threads.

A further improvement is that circular arc notches are arranged on both sides of the positioning mold in the stator and the left fixed plate, and the purpose of setting the circular arc notches is to make the three-phase line notch of the motor fixed to the left side of the airtight device. The notch of the plate is put into the tooling correspondingly.

The beneficial effect of the utility model is that the moving distance of the stator sealing sleeve and the stator fixing chuck can be adjusted through threads, the fixing strength of the pressure head to the motor can be conveniently controlled, the air tightness inspection is reliable, and the operation is also simple and convenient.
