At the same time, the Z-direction vibration sensor 324 contacts the bottom of the product 7, and then the product 7 is clamped by four sets of pneumatic clamps 323. Then, the X-direction vibration sensor 326 is driven by two translation cylinders 325 to contact the side of the product 7. Finally, the vibration platform 31 drives the test carrier 32 and the product 7 to vibrate. During the vibration process, the Z-direction vibration sensor 324 and the X-direction vibration sensor 326 jointly detect the vibration frequency of the product 7 to determine the abnormal sound.

[0051] Further, if Figure 7 As shown, the screw-nut assembly includes a screw 523 arranged at the bottom of a supporting plate 521, a servo motor 524 arranged at the bottom of the supporting plate 521 for driving the screw 523 to rotate, and nuts 525 respectively arranged on both sides of the screw 523; the threads on both sides of the screw 523 have opposite rotation directions; a pair of jaws 522 are respectively arranged at the bottom of two nuts 525, and the jaws 522 and the nuts 525 are connected by a dovetail groove quick-change structure 526.

[0052] During operation: the lead screw 523 is driven to rotate by the servo motor 524. Since the threads on both sides of the lead screw 523 rotate in opposite directions, the two nuts 525 drive a pair of jaws 522 to move closer or farther away at the same time, and the jaws 522 and the nuts 525 are connected by a dovetail groove quick-change structure 526 for easy replacement; the dovetail groove quick-change structure 526 is an existing structure, so its structure will not be described in detail.
