Specific embodiment
In order to make the purpose of this utility model, advantage and embodiment seem be more clear it is clear, now in conjunction with specific implementation
The utility model will be further described for example, it should be understood that embodiment described herein is only to the utility model
It illustrates, does not constitute limitations of the present invention.
A kind of motor rotor testing instrument as shown in FIG. 1 to FIG. 3, including pedestal 1 are fixedly installed with motor 2 on pedestal 1, electricity
Rotor axle sleeve 3 is connected in 2 shaft of machine, 3 upper end of rotor axle sleeve is provided with rotor rack 4, and rotor is placed across rotor
4 bottom end of frame is set in inside rotor axle sleeve 3, and the rotation of rotor axle sleeve 3 is driven by motor, and drives rotor rotation.On rotor rack
Side is provided with low resistance tester 5, and low resistance tester 5 is pushed up by support rod 6 with the backboard 7 that 1 side of pedestal is arranged in
Portion be connected, rotor in the course of rotation, open low resistance tester 5 on switch, using low resistance tester 5 to turn
Son is tested, and shown result is shown on the display screen on low resistance tester 5, if meeting the requirements, product is
Non-defective unit need to be dismantled conversely, being then substandard products and carry out repeating installation.The first cylinder 8 is fixedly installed on backboard 7, the first cylinder 8 is living
It is fixedly connected with limit plate 9 on stopper rod, the positioning pin 10 to match with 4 lateral through aperture of rotor rack is provided on limit plate 9,
Positioning pin 10 is 2, is symmetrically arranged along 9 middle line of limit plate, does not detect under transition, positioning pin 10 is located at rotor rack 4
Outside, when detection, positioning pin 10 protrudes into rotor rack across through-hole under the action of the first cylinder 8 driving limit plate 9 moves
Inside 4, and the two sides of rotor are respectively distributed to, make the gap between rotor and positioning pin 10 there are 0.5-1mm, is avoided that and turn
Son in high-speed rotation there is a phenomenon where centrifugation deviate, influence test result, but can guarantee rotor can free high speed operation.
Wherein, as shown in Figure 4, Figure 5, rotor rack 4 is set as strip, and inner space can accommodate multiple rotors,
