[0002] The pulley belongs to the hub type parts, which are generally relatively large in size. The manufacturing process is generally based on casting and forging.

[0003] When the pulley is running, it will vibrate due to various reasons such as processing errors. These vibrations are inevitable, but must be kept within a certain safety range.

[0065] Example 3:

[0066] like Figure 4-Figure 7 As shown, the structure of the mechanical vibration measuring device for pulley production disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that:

[0067] A groove 22 is formed at the center of the upper end of each clamping plate 4, and a flap 12 is provided inside each groove 22;

[0075] A second exhaust pipe 32 is provided between each of the air storage chambers 33 and the corresponding first exhaust pipe 25;

[0076] During the clamping process, the flexible extrusion plate 13 is squeezed, and the first air storage bag 24 on one side of the flexible extrusion plate 13 is compressed. The gas inside the first air storage bag 24 is discharged to the inside of the second air storage bag 27 through the first exhaust pipe 25. The second air storage bag 27 expands, pushing the transmission rack 30 to rise, and the transmission rack 30 drives the flap 12 to flip through the rotating shaft 29. When flipping, it gradually contacts the surface of the pulley and squeezes the pulley downward to ensure that the pulley is in close contact with the surface of the adjusting disk 3 and no tilting occurs.

[0077] Example 4:

[0078] like Figures 8-10 As shown, the structure of the mechanical vibration measuring device for pulley production disclosed in the fourth embodiment of the present invention is basically the same as that in the third embodiment, except that:

[0079] A storage plate 5 is provided at the upper end of the base plate 1 , and a first electric telescopic rod 6 is provided at the center of the storage plate 5 . The output end of the first electric telescopic rod 6 passes through the storage plate 5 and is connected to a fixing plate 7 .

[0080] A sleeve 40 is rotatably connected to the center of the lower end of the fixing plate 7. A countersunk hole 43 is formed at the lower end of the sleeve 40. A transmission rod 41 is inserted into the interior of the countersunk hole 43. A third return spring 44 is provided between the upper end of the transmission rod 41 and the top end of the interior of the countersunk hole 43.

[0081] A spiral groove 47 is formed on the inner wall of the counterbore 43 at a position corresponding to the outer surface of the transmission rod 41 , and a spiral block 48 is provided on the outer surface of the transmission rod 41 at a position corresponding to the spiral groove 47 ;

[0082] At least one set of slide grooves 45 is formed on the outer surface of the sleeve 40 , a cleaning plate 9 is slidably arranged inside the slide groove 45 , and a fourth return spring 46 is provided between the inner top end of the slide groove 45 and the upper end of the cleaning plate 9 .

[0083] The fixing plate 7 is provided with a second guide groove 37, in which a third electric telescopic rod 38 is slidably arranged. A second electric telescopic rod 36 is installed at a position on the side wall of the fixing plate 7 corresponding to the position of the third electric telescopic rod 38, and an output end of the second electric telescopic rod 36 is connected to the side wall of the third electric telescopic rod 38.

[0084] The output end of the third electric telescopic rod 38 is connected to a vibration sensor 8;

[0085] After the pulley is placed, the transmission rod 41 can be driven by the fixed plate 7 to make close contact with the pulley surface. When the transmission rod 41 contacts the pulley and the fixed plate 7 continues to move downward, the sleeve 40 will move downward relative to the transmission rod 41. At this time, under the cooperation of the spiral groove 47 and the spiral block 48, the sleeve 40 drives the cleaning plate 9 to rotate. The bristles provided on the cleaning plate 9 can clean the pulley surface to prevent waste chips adhering to the pulley from affecting the measurement results.

[0086] During measurement, the position of the vibration sensor 8 is adjusted by the second electric telescopic rod 36, and then the third electric telescopic rod 38 is started. The third electric telescopic rod 38 drives the vibration sensor 8 to move toward the pulley to measure the pulley.

[0087] The specific solution is as follows: the pulley is placed at the center position on the adjusting disk 3, and then the fixed plate 7 drives the transmission rod 41 to make close contact with the surface of the pulley. When the transmission rod 41 contacts the pulley and the fixed plate 7 continues to move downward, the sleeve 40 will move downward relative to the transmission rod 41. At this time, under the cooperation of the spiral groove 47 and the spiral block 48, the sleeve 40 drives the cleaning plate 9 to rotate, and the bristles provided on the cleaning plate 9 can clean the surface of the pulley. After cleaning, the fixed plate 7 is reset.

[0088] Then, the motor 21 is started, and the turntable 15 is driven to rotate through the cooperation between the motor 21, the transmission gear 20, and the first transmission tooth groove 18. When the turntable 15 rotates, the limiting groove 16 and the first guide groove 10 cooperate to achieve the mutual approach of the multiple clamping plates 4, thereby clamping the pulley;

[0089] During the clamping process, the flexible extrusion plate 13 is squeezed, and the first air storage bag 24 on one side of the flexible extrusion plate 13 is compressed. The gas inside the first air storage bag 24 is discharged to the inside of the second air storage bag 27 through the first exhaust pipe 25. The second air storage bag 27 expands, pushing the transmission rack 30 to rise. The transmission rack 30 drives the flap 12 to flip through the rotating shaft 29. When flipping, it gradually contacts the surface of the pulley and squeezes the pulley downward to ensure that the pulley is in close contact with the surface of the adjusting disk 3 and does not tilt.

[0090] After the clamping is completed, the position of the vibration sensor 8 is adjusted by the second electric telescopic rod 36, and then the third electric telescopic rod 38 is started, and the third electric telescopic rod 38 drives the vibration sensor 8 to move toward the pulley to perform vibration measurement on the pulley.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
