Step 3, due to the different heights and lengths of the motors to be detected of different specifications, when the motor to be detected moves close to the vibration sensor 7, it cannot directly conflict with the vibration sensor 7, and then by adjusting the height of the driving handle 8 on the mounting block 6 , that is, when the driving handle 8 is located in the middle of the mounting block 6, a force is applied to the driving handle 8 in a direction close to the turntable 28. At this time, the mounting block 6 located on the side of the driving handle 8 away from the T-shaped slider 5 is always kept vertical state, the installation block 6 located on the side of the drive handle 8 far away from the T-shaped slider 5 will slide relative to each other. Control, that is, the installation block 6 takes the position of the driving handle 8 as the moving point, the installation block 6 below the driving handle 8 slides relative to each other, and the installation block 6 above the driving handle 8 (including the position of the driving handle 8) maintains a vertical angle to drive the vibration The sensor 7 moves so that the mounting block 6 on the lower side is distributed in steps, and then drives the vibration sensor 7 to approach the motor to be detected and conflict with the motor, and adjust the height of the driving handle 8 on the mounting block 6 according to the height and distance of the motor to be detected , so as to ensure that motors of different specifications can interfere with the vibration sensor 7 during detection.

Step 4, when one side of the motor to be detected moves to contact with the vibration sensor 7, stop moving. At this time, the staff drives the vibration sensor 7 to move through the cooperation of the driving handle 8 and the T-shaped slider 5, and fits the motor to be detected. The vibration sensor 7 transmits the vibration data of the motor to the background display screen. When other orientations need to be detected, the pull ring 210 drives the positioning rod 29 to rise and move. At this time, the limit ring 211 drives the return spring 212 to shrink to make the positioning rod After one end of 29 breaks away from positioning hole 26;

Step 5, turn the turntable 28. At this time, since the upper arc clamp 313 and the lower arc clamp 34 are engaged with the outside of the motor to be detected, when the lower arc clamp 34 rotates through the turntable 28, it drives the motor to be detected to rotate , and then drive the upper arc-shaped clamping block 313 to rotate, thereby maintaining the relative position of the upper arc-shaped clamping block 313 and the lower arc-shaped clamping block 34 without changing, the cooperation between the upper arc-shaped clamping block 313 and the lower arc-shaped clamping block 34 drives the The detected motor is rotated and adjusted. When it is adjusted to the ideal position, the pull ring 210 is loosened. At this time, the reset effect of the return spring 212 drives the positioning rod 29 to move down through the limit ring 211, so that one end is inserted into the positioning hole 26 to limit the position. Fixed, at this time, the vibration sensor 7 is driven to move by the cooperation of the driving handle 8 and the T-shaped slider 5 again, and is attached to another direction of the motor to be detected for detection.

Finally, it should be noted that the above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still understand The technical solutions recorded in the foregoing embodiments are modified, or some of the technical features are equivalently replaced, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the present invention. within the scope of protection.
