step three, because the height and the length of the motors to be detected with different specifications are different, when the motors to be detected move towards the vibration sensor 7, the motors cannot directly abut against the vibration sensor 7, and further, by adjusting the height of the driving handle 8 on the mounting block 6, namely when the driving handle 8 is positioned at the middle position of the mounting block 6, a force in the direction close to the turntable 28 is applied to the driving handle 8, at the moment, the mounting block 6 positioned at one side of the driving handle 8, which is far away from the T-shaped sliding block 5, is always kept in a vertical state, the mounting block 6 positioned at one side of the driving handle 8, which is far away from the T-shaped sliding block 5, performs relative sliding on the mounting block 6, and when the mounting block 6 performs position movement, attention needs to be paid to control the moving height of the mounting block 6 through the position of the driving handle 8, namely, the mounting block 6 performs relative sliding on the mounting block 6 below the driving handle 8 by taking the position point of the driving handle 8 as a moving point, lie in more than the drive handle 8 (including drive handle 8 position) keep vertical angle degree to drive vibration sensor 7 and remove for installation piece 6 of downside is cascaded distribution, and then drives vibration sensor 7 and is close to waiting to detect the motor and contradict with the motor, and according to waiting to detect the height of motor and the height of distance adjustment drive handle 8 on installation piece 6, thereby ensure that the motor of different specifications can both contradict with vibration sensor 7 when detecting.
Step four, when one side of the motor to be detected moves to be in contact with the vibration sensor 7, the movement is stopped, at the moment, a worker drives the vibration sensor 7 to move through the matching of the driving handle 8 and the T-shaped sliding block 5 and is attached to the motor to be detected, the vibration sensor 7 transmits vibration data of the motor to a background display screen, when other directions need to be detected, the positioning rod 29 is driven to move upwards through the pull ring 210, at the moment, the limit ring 211 drives the reset spring 212 to contract, and one end of the positioning rod 29 is separated from the positioning hole 26;
step five, the rotating disc 28 is rotated, at this time, the upper arc-shaped clamping block 313 and the lower arc-shaped clamping block 34 are clamped outside the motor to be detected, so that when the lower arc-shaped clamping block 34 rotates through the rotating disc 28, the motor to be detected is driven to rotate, the upper arc-shaped clamping block 313 is driven to rotate, the relative position of the upper arc-shaped clamping block 313 and the lower arc-shaped clamping block 34 is maintained unchanged, the motor to be detected is driven to rotate and adjust through the matching of the upper arc-shaped clamping block 313 and the lower arc-shaped clamping block 34, when the ideal position is adjusted, the pull ring 210 is loosened, at this time, the reset effect of the reset spring 212 drives the positioning rod 29 to descend and move through the limiting ring 211, one end of the positioning rod is inserted into the positioning hole 26 for limiting and fixing, at this time, the vibration sensor 7 is driven to move through the matching of the driving handle 8 and the T-shaped sliding block 5 again, and the other direction of the motor to be detected is attached to be detected for detection.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
