Description
Technical field
The utility model belongs to motor performance test field, more specifically to a kind of motor air tightness test tooling.
Background technique
Motor needs to carry out in process of production IP level estimate, and motor is steeped in 1 meter of depth of water and is tested, to detect electricity
Sealing performance between the drive end bearing bracket of machine, rear end cap, outlet box and casing, efficiency is slow and motor is once testing and not crossing not will lead to
Motor entering water is scrapped.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of when carrying out air tightness test to motor, is not necessarily to
Put it into it is underwater, operating procedure faster, and the motor air tightness test tooling for avoiding motor entering water from scrapping.
To achieve the above object, the utility model provides following technical solution: a kind of motor air tightness test tooling, packet
Pedestal is included, portal frame is provided on pedestal, lower air cylinder is provided on the portal frame, is provided with gland below lower air cylinder,
Shaft end of the gland to cover motor, the gland is interior to have the cavity communicated with motor, offers stomata, the gas on gland
There is inflation mechanism in hole by piping connection, and air gauge is provided on pipeline, is provided with gas between the air gauge and inflation mechanism
It compresses switch.
The cushion block to positioning motor is provided on the further pedestal.
It is provided with positioning slide on the further pedestal, the cushion block is slidably connected with positioning slide.
It is mutually indepedent between the further gland and lower air cylinder.
The further gland is provided with seal groove towards pedestal side, is provided with sealing ring in seal groove.
The further inflation mechanism is air pump.
Compared with prior art, the utility model has the beneficial effects that motor is placed on pedestal, and makes axis in test
End upward, and passes through the front end cap surface that is attached to motor of the lower air cylinder by gland only；Pass through air-pump inflating to required air pressure
After close baroswitch, air gauge is observed in pressure maintaining, such as is declined without numerical value, is then shown that waterproof performance reaches a standard, otherwise unqualified, is detected
It is high-efficient, and the unqualified product of air-tightness will not intake and scrap, it can carry out ressembling detection using again.

Specific embodiment
It is described further referring to figs. 1 to embodiment of the Fig. 4 to the utility model motor air tightness test tooling.
A kind of motor air tightness test tooling, including pedestal 1 are provided with portal frame 2 on pedestal 1, set on the portal frame 2
It is equipped with lower air cylinder 7, is provided with gland 6 below lower air cylinder 7, axis 55 end of the gland 6 to cover motor 5, in the gland 6
With the cavity communicated with motor 5, stomata 61 is offered on gland 6, the stomata 61 has inflation mechanism by piping connection, pipe
Road is provided with air gauge 8, is provided with baroswitch between the air gauge 8 and inflation mechanism.
Wherein inflation mechanism is preferably air pump, using air compressor machine or electric air pump.
As shown in Figure 1, the oil sealing between the drive end bearing bracket 53 and axis 55 of motor 5 does not fill first in test, motor 5 is placed on
On pedestal 1,55 end of axis of motor 5 makes gland 6 be tightly attached to the drive end bearing bracket 53 of motor 5 towards lower air cylinder 7, by lower air cylinder 7
On, by air-pump inflating, gas is made to pass sequentially through pipeline, stomata 61, cavity to the inside of motor 5, air-tightness as needed
Grade observes the numerical value of air gauge 8, when it reaches respective value, closes baroswitch (i.e. valve), not reinflated, reaches
State of pressure keeping, stands whether observation 8 numerical value of air gauge has decline, shows that 5 air-tightness of motor is qualified if without decline, i.e. drive end bearing bracket
53, sealing between rear end cap 51, outlet box 52 and casing 54 is qualified, on the contrary be it is unqualified, after lower air cylinder 7 is answered
Position, motor 5, which is removed, can carry out next test, the qualified final oil seal shaft 55 of motor 5 and drive end bearing bracket 53.
Test process can avoid the water inlet of motor 5 and scrap, 5 surface of motor will not be led because soaked without being put into deep water
Problem of rustiness is caused, landed cost is reduced.
The present embodiment is preferably provided with the cushion block 3 to positioning motor 5 on the pedestal 1, is provided on the pedestal 1
Positioning slide 4, the cushion block 3 are slidably connected with positioning slide 4, according to the replaceable corresponding cushion block of different motors 53 with more
Firmly motor 5 is fixed, while when replacing the test of motor 5, cushion block 3 is slided by positioning slide 4, facilitates motor 5
Load onto and remove.
The present embodiment is preferably mutually indepedent between the gland 6 and lower air cylinder 7, is testing the airtight of different motors 5
Property when, can according to 53 size and shape of drive end bearing bracket of its motor 5 replace gland 6, so that gland 6 is held against with drive end bearing bracket 53
Sealing state；Certain gland 6 can also be connect between lower air cylinder 7 by detachable structure.
One pressing plate 76 preferably is set in 7 lower end of lower air cylinder, to contact with gland 6, increases contact area.
Preferably the gland 6 towards 1 side of pedestal is provided with seal groove 62 to the present embodiment, is provided in seal groove 62 close
Seal, seal groove 62 can limit sealing ring, and the deviation when being squeezed deformation to avoid sealing ring can be such that sealing ring bears
Biggish pressure.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
