[0049] like Figures 1 to 10As shown, the present invention discloses a needle roller chamfering machine and its method of use. During operation, firstly, several prepared needle rollers are fed through the feed inlet of the rear support plate 2 onto a storage tank 6 aligned with the feed inlet of the rear support plate 2. The storage tank 6 is tilted forward, causing the needle rollers to roll forward. Simultaneously, the front support plate 2 limits the movement of the needle rollers in the storage tank 6. Then, the reduction motor 4 is activated, driving the conveyor belt 5 via two sets of rotating shafts 3 to transport the needle rollers upwards. Simultaneously, another set of storage tanks 6 is aligned with the feed inlet of the rear support plate 2. The above steps are repeated to continue feeding the prepared needle rollers onto the storage tank 6 aligned with the feed inlet of the rear support plate 2, causing the needle rollers to... The discharge port of the front support plate 2 rolls onto the guide groove 7, guiding the needle rollers to the limiting device. Then, the second pressure sensor 14 blocks the front end of the guide groove 7, limiting the needle rollers on the guide groove 7. During loading, the first cylinder 11 retracts, causing the clamp 13 to move upwards, allowing a set of needle rollers to roll from the guide groove 7 to the top of the processing table 9. Then, the first cylinder 11 extends, causing the clamp 13 to lightly press onto the needle rollers. Simultaneously, the first pressure sensor 12 detects the downward pressure of the first cylinder 11, limiting the needle rollers. When the second pressure sensor 14 detects the pressure disappearing, the conveyor belt 5 moves another set of storage tanks 6... The needle rollers are arranged on the guide groove 7. The first drive motor 16 is turned on, and the first gear 17 meshes with two sets of second gears 18 to drive the support base 19 to rotate 90 degrees, so that the support columns 23 on the two sets of chamfering devices are aligned with the two ends of the needle rollers.

Then the second gear 18 drives the support base 19 to rotate 90 degrees, so that the chamfering cutters 26 on the two sets of chamfering devices are aligned with the two ends of the needle rollers. The second drive motor 25 drives the chamfering cutters 26 to rotate, and the third cylinder 24 extends, so that the chamfering cutters 26 on the two sets of chamfering devices are aligned with the two ends of the needle rollers. The ends are chamfered, and then the support base 19 is rotated 180 degrees by the second gear 18, so that the grinding tools 28 on the two sets of grinding devices are aligned with the two ends of the needle roller. The two ends of the needle roller are ground by the grinding tools 28 on the two sets of grinding devices. Then the air is compressed by the air compressor 29. When discharging, the first cylinder 11 is contracted to release the needle roller on the processing table 9. At the same time, the second pressure sensor 14 is still blocking the front end of the guide groove 7. Compressed air is sprayed out by the nozzle 30 to blow the needle roller at the top of the processing table 9 down, so that the needle roller falls into the storage box 31. The falling dust is separated from the needle roller by the partition screen, so that the dust falls below the partition screen.
