Description

Technical Field

[0001] This invention relates to the field of bearing vibration detection technology, and in particular to a bearing vibration detection device. Background Technology

[0002] In the field of mechanical manufacturing, bearings are core components of rotating equipment, and their vibration characteristics are one of the important indicators for measuring bearing quality. Vibration testing can detect machining errors, assembly defects, or damage inside the bearing early, thereby preventing them from causing failures during equipment operation. Bearing vibration testing typically requires mounting the bearing on a mandrel or drive shaft on a dedicated test bench and measuring its vibration acceleration or velocity values ​​under a given speed and load.

[0003] Currently, most conventional bearing vibration testing devices employ a single-station design, meaning only one bearing can be installed and tested at a time. After testing, the machine needs to be stopped, the tested bearing removed, and the next bearing to be tested clamped, resulting in lengthy auxiliary time and low testing efficiency. Especially in batch testing scenarios, frequent loading and unloading operations not only increase labor intensity but also limit further capacity expansion. Furthermore, existing testing equipment often requires changing mandrels or adjusting tooling to accommodate differences in bearing inner diameter and width when switching between different bearing specifications, making the operation cumbersome and time-consuming. When a bearing's vibration value exceeds the standard during testing, it must be manually removed from the station and sorted, with processing speed limited by operator response time. If multiple non-conforming products appear consecutively, manual sorting can easily cause process interruptions or confusion, affecting the continuity of testing and the accuracy of non-conforming product management. Simultaneously, since most testing devices can only process one item at a time and cannot automatically remove defective products without interrupting the testing process, qualified and non-conforming products still need to be manually sorted later, adding an extra step and reducing overall efficiency.

[0026] refer to Figures 9 to 12 As shown, the drive assembly 3 includes a mounting plate 301 slidably mounted on the lower end of the base 101. A motor 122 is also provided at the lower end of the base 101. A lead screw is provided on the output shaft of the motor 122. The mounting plate 301 and the lead screw of the motor 122 are connected by threads. When the motor 122 starts, it drives the mounting plate 301 to slide on the base 101. A mounting post 304 is rotatably provided at the upper end of the mounting plate 301. Multiple sets of locking blocks 307 are slidably provided in the mounting post 304. A spring 314 is provided between the mounting post 304 and the locking blocks 307. When the locking blocks 307 move away from the axis of the locking blocks 307, the locking blocks 307 press against the inner ring 207 of the bearing.

[0027] A gear 305 is coaxially mounted on the mounting post 304, and a motor 308 is mounted on the mounting plate 301. A gear 309 is mounted on the output shaft of the motor 308. Gear 305 meshes with gear 309. When the motor 308 starts, it drives gear 309 to rotate. Gear 309 drives gear 305 and the mounting post 304 to rotate. The mounting post 304 drives the bearing to be inspected to rotate.

[0028] The drive assembly 3 also includes an electric cylinder 302. A support block 303 is provided on the movable end of the electric cylinder 302. A locking pin 306 is rotatably provided on the upper end of the support block 303. Multiple sets of locking blocks 310 are slidably provided on the locking pin 306. A groove is provided on the inner side of the locking blocks 310. An electric cylinder 311 is provided inside the support block 303. A locking rod 312 is rotatably provided on the movable end of the electric cylinder 311. A cone 313 is provided on the locking rod 312.

The locking rod 312 presses the locking blocks 310. The locking blocks 310 press the locking blocks 307. The locking blocks 307 press the inner side of the bearing inner ring 207, thus fixing the locking blocks 307 to the bearing outer ring 206.

[0029] Working principle: During operation, the drive motor 113 drives the placement tray 201 to the top of the recycling bin 110. The bearing is then manually placed on the placement rack 202. Multiple placement racks 202 are then stacked on the placement tray 201. After the placement racks 202 are placed, the placement tray 201 is driven to the bottom of the pressing plate 108. The pressing plate 108 moves and presses down on the multiple placement racks 202 to ensure the stability of the placement tray 201 and the placement racks 202. At the same time, the two pressing plates 118 are driven to move closer to each other. The pressing plates 118 press down on the push plate 203. The two push plates 203 drive the clamping blocks 205 to move closer to each other. The clamping blocks 205 fix the outer ring 206 of the bearing.

[0030] When the bearing needs to be driven to rotate, the electric cylinder 123 is activated. The electric cylinder 123 moves the baffle 124 to engage with the limit post 208, locking the mounting bracket 202 containing the bearing that does not need to be tested. The mounting plate 301 then slides on the base 101, causing the mounting post 304 to insert into multiple sets of mounting brackets 202. This ensures that each set of locking blocks 307 on the mounting post 304 is aligned with a set of bearing inner rings 207. Subsequently, the electric cylinder 302 is activated, moving the support block 303. The support block 303 then moves the locking post 306 and the electric cylinder... When cylinder 311 moves, initially, cone 313 does not press on locking block 310. When locking pin 306 drives locking block 310 to align with a set of bearings that need to be driven, cylinder 311 is activated. Cylinder 311 drives locking rod 312 to move, locking rod 312 drives cone 313 to move, cone 313 presses on multiple sets of locking blocks 310, multiple sets of locking blocks 310 press on locking block 307, locking block 307 presses on bearing inner ring 207, thus completing the fixation of locking block 307 and bearing inner ring 207.

[0031] The drive detection frame 104 and the detection head 105 are engaged with the outer ring 206 of the bearing on the set of bearings to be tested. At this time, the motor 308 is started. The motor 308 drives the mounting column 304 to rotate. The mounting column 304 drives the locking block 307, the locking block 310, and the cone head 313 to rotate. The locking block 307 drives the inner ring 207 of the bearing to rotate. The bearing is driven and the vibration of the bearing is detected.

[0032] After the inspection is completed, when it is necessary to remove the bearings with problems, the drive placement plate 201 is driven to reach above the recycling bin 110, and the drive lifting plate 115 is inserted into the lower end of the placement rack 202 above the set of bearings with problems. The drive lifting plate 115 removes the placement rack 202 above. Then, the motor four 119 is started, which drives the adjustment plate three 121 to move. The adjustment plate three 121 drives the lifting frame 125 to align with the set of placement racks 202 containing the bearings with problems. The drive clamping plate 127 is started to approach the lifting frame 125 to clamp the placement rack 202. The drive lifting frame 125 moves to remove the placement rack 202, completing the removal of the bearings with problems.
