Description
Technical field
The invention belongs to technical field of motor manufacture, more particularly, to a kind of setting using the multiple motor housings of liquid detecting
It is standby.
Background technique
Water-cooled machine is to cross to carry out Water-cooling circulating on motor housing all, thus the heat inside the heat and motor in water
Amount is replaced, and then is realized and cooled down to motor, and the motor is because of the heat dissipation by the way of water cooling, to motor itself
Requirement it is small, therefore its applicable range is wide, can be used for more narrow confined space；But water-cooled machine is because using water cooling
Mode, therefore it has biggish difficulty in the technical process of manufacture, especially in the manufacturing process of motor housing, needs
The problems such as ensureing that motor housing is completely seamless, otherwise will cause leak causes heat dissipation effect poor, can not effectively carry out scattered
Heat, setting are that water penetration enters inside motor, cause internal short-circuit, motor damage.
Its in existing motor housing detection process be mostly motor housing is blocked after, be placed in water, then pass through to
It ventilates in motor housing, whether have bubble generate to judge motor housing whether there is gap, but existing if observing in water
Motor test equipment during detection produce comparatively fine because the gap of motor housing is logical, examined to motor housing
It is difficult to really quickly and effectively detect gap during survey, the effect that will cause detection is poor, and the process detected
In its detect that time-consuming, detection efficiency is low.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides that a kind of structure is simple, detection efficiency is high, detection effect is good
Utilize the equipment of the multiple motor housings of liquid detecting.
To achieve the goals above, the invention adopts the following technical scheme: a kind of utilize the multiple motor housings of liquid detecting
Equipment, including
Detection case；
Testing stand is set in the detection case, for placing the motor housing；
Detection device is set on the testing stand, and when multiple motor housings are placed on the testing stand, detection device is same
When block the motor shell opening and be passed through gas into motor housing；
Feed liquor component, Yu Suoshu detection device inject liquid into the detection case after matching with motor housing from the bottom to top
Body is to the excessively not described motor housing；
Drain component, the liquid level that will test liquid after the completion of the detection of Yu Suoshu motor housing drop to motor housing or less；
Heating element, for heating up motor housing with gap existing on distending motor housing.
The present invention can heat liquid by the way that heating element is arranged, so that liquid is at a certain temperature, to electricity
Motor housing is heated during machine shell is detected, and enables gap present on motor housing using the principle expanded with heat and contract with cold
That enough opens more increases, thus be passed through gas after can faster go out in motor housing convenient for gas and form gas
Bubble can be quickly detected the gap generated on motor housing during being somebody's turn to do, and detection effect is good, and detection is time-consuming short, detection effect
Rate is high；Setting detection device synchronizes detection to multiple motor housings, shortens the time blocked to motor housing, improves
To the detection efficiency of motor housing, manually-operated workload is reduced, the production efficiency of motor is improved；And in the process of detection
In by feed liquor component by detection case bottom towards detection upper box part feed liquor, the feed liquor process avoid traditional top feed liquor and
Spray is caused to influence detection effect, the time needed for shortening detection；And drain component is arranged can then incite somebody to action after detection is completed
Liquid level decline so that motor housing is located at liquid level hereinafter, being convenient for taking out electrode shell, while being also avoided that and taking out outside motor
It causes the appearance of internal liquid significantly to shake and blister during shell, ensures the subsequent process for refilling detection liquid
Liquid level does not fluctuate steadily；And feed liquor component and the mutual cooperation of liquid component out, realizing can be every to the liquid in detection case
It is secondary all to be replaced, it keeps liquid its whole cleanliness in detection case high, avoids liquid muddy and cause to detection effect
Erroneous judgement.
