end of the lifting driving device 7 is hinged and fixed to a portion of the moving
plate 5 deviated from the driving wheel 51, while a lower end thereof is hinged
and fixed to the soleplate. The lifting driving device 7 is an air cylinder.
The motor holder 2 is fixed on a slider 80, the slider 80 is slidingly fixed on

and right ends of the holding plate 20, respectively.
The supports 3 include a first support 31 and a second support 32. The
first support 31 is located on the left side of the second support 32. The end
face runout detection sensor 4 is located above the first support. The second
support 32 is located on the right of the end face runout detection sensor 4. A
second limiting portion 33 is arranged on a side of the second support 32 away

When in use of the device of the present invention, a standard motor is
placed on the motor holder. Then, the standard motor is pushed to the end
face runout detection sensor side, and the limiting member in the second
limiting portion is adjusted left and right so that the plane of the front end face
of the front end cover on the left side of the standard motor is located on the
left side of the right edge of the right end of the end face runout detection
sensor, and the plane of the front end face of the front end cover has a
distance of 1 mm to 2mm from the right edge of the right end of the end face
runout detection sensor. Subsequently, the standard motor is taken down for
detection of a motor to be detected.
The right end of the output shaft of the motor to be detected is resisted
against the end of the limiting member in the second limiting portion so as to
compress the compression spring in the limiting member. Then, the motor to
be detected is put down such that the left end of the output shaft of the motor
to be detected can fall into the locating groove on the first support.
Subsequently, a limiting member is optionally placed in the fixation hole in the
first limiting portion. By the limiting member in the first limiting portion, the
leftward slide of the motor is limited, and it is ensured that the compressed
amount of the compression spring of the limiting member in the first limiting
portion is as low as possible.
Subsequently, the linear driving device is activated to move the motor
holder toward the end face runout detection sensor. The axial face of the front
end cover of the motor on the motor holder comes into contact with the
cambered surface of the end of the end face runout detection sensor, and the
end face runout detection sensor is then compressed such that the right end of
the end face runout detection sensor is resisted against the end face of the
front end cover.
Next, the lifting driving device is activated to allow the conveying belt to
adhere onto the motor shell, and the conveying belt is driven to rotate by the
driving device so as to drive the motor shell to rotate about the output shaft, so
that the end face runout detection is realized.
The present invention has the advantages of convenient use and high
detection accuracy.
