Description
Technical field
The present invention relates to field of motor manufacturing more particularly to a kind of motor gas-gap detection devices.
Background technology
The air gap between stator and rotor need to be detected after the completion of motor assembly and when overhauling, at present the inspection of major part motor gas-gap
Survey is detected by artificial clearance gauge, but for the motor with aerofoil fan, since detection space is small, and Wu Fali
Manually clearance gauge is detected.
Invention content
It is an object of the invention to overcome disadvantages described above, provide a kind of not by the motor gas-gap detection device of spacial influence.
The technical scheme is that a kind of motor gas-gap detection device comprising axle sleeve, the axle sleeve is by two valves or two
More than valve be formed by connecting, the inner circle of axle sleeve matches with the shaft shoulder outer diameter of rotor end, and axle sleeve can along the shoulder rotational,
It is equipped with connecting platform in the outer circle of axle sleeve, detection needle is fixed on by activity folder and holder on connecting platform, activity folder edge
Holder up and down adjustment detects the height and position of needle, and the detection needle is one group of diameter and the similar inspection of air-gap design value to be detected
Stylus group.
Needle is detected for the ease of observation, further includes camera and display with light source, camera production detection needle simultaneously will
Realtime graphic is shown by display.
For the ease of installation, the axle sleeve is track structure comprising connecting plate, stem connecting plate are connected with tail portion
Plate, after two or more connecting plates are connected by axis pin, both ends pass through axis pin and stem connecting plate and tail portion again respectively
Connecting plate connects into crawler belt, together with stem connecting plate is bolted with the end of tail portion connecting plate, forms an internal diameter
Match with the shaft shoulder and can be along the crawler belt set of shoulder rotational.
For the ease of adjusting the tightness between crawler belt set and the shaft shoulder, it is equipped between stem connecting plate and tail portion connecting plate
Gap, by adjusting bolt tighten degree ensure crawler belt set flexibly rotated on the shaft shoulder.
In order to protect the shaft shoulder, it is copper coin or aluminium sheet that the connecting plate, stem connecting plate, which connect plate material with tail portion,.
The method have the benefit that the outer circle in axle sleeve is equipped with connecting platform, detection needle is pressed from both sides by activity and branch
Frame is fixed on connecting platform, and activity folder detects the height and position of needle along holder up and down adjustment, and detection needle is one group of diameter and wait for
The air-gap design value of detection is similar to detect needle group, so as to make detection needle by the height of the rotation of axle sleeve and adjusting activity folder
In the air gap of stator and rotor, whole circle air gap is detected.
