[0025] The electric spindle comprehensive performance detection device and detection method thereof, by setting a detection mechanism, fixes the position of the sensor and protects the wiring on the top of the sensor. When the sensor moves between the front bearing and the rear bearing of the electric spindle, the wiring on the top of the sensor is pulled up to prevent the wiring from being hit by other equipment and thus damaging the sensor. At the same time, the sensor reciprocates between the front bearing and the rear bearing and is fixed on the front bearing or the rear bearing to collect vibration conditions, which can prevent the sensor from falling off due to manual placement and vibration of the electric spindle.

[0060] As the detection work is carried out, it can be observed whether there is a spring sheet popped out. If there is a spring sheet popped out, the spring sheet falls within the range of the inclined plate 801 and the buckle plate 802 to prevent the spring sheet from hurting the user.

The third telescopic rod 602 is turned on, and the third telescopic rod 602 drives the positioning cylinder 603 and the sensor to move downward until the sensor contacts the front bearing of the electric spindle to detect the vibration of the front bearing of the electric spindle.

[0069] Adjust the speed and then repeat the above operation to detect the vibration values ​​of the front and rear bearings of the electric spindle at different speeds.

As the detection work proceeds, it can be observed whether there is a spring sheet popped out. If there is a spring sheet popped out, the spring sheet falls within the range of the inclined plate 801 and the buckle plate 802 to prevent the spring sheet from hurting the user.

[0072] After the inspection is completed, the electric spindle is removed and the motor is turned on again. The motor drives the rotating shaft 804, the connecting rod 805, the arc plate 806 and the rotating cylinder 7 to rotate 90 degrees, and the spring sheet is manually removed.
