Description

Technical Field

[0001] This utility model relates to the field of steel ball testing equipment, specifically a sorting and feeding device for steel ball testing. Background Technology

[0002] Steel balls are the most important component of bearings and the most widely used rolling elements in the bearing industry. The quality of steel balls directly affects the bearing's precision, motion performance, and service life. Currently, domestic bearing manufacturers and steel ball factories mainly rely on manual inspection to detect surface defects in steel balls. This results in a high rate of false positives and false negatives. Identifying the types and sizes of surface defects is difficult to do quickly by eye. Even when using inspection equipment, manual feeding is still required, leading to low automation levels that hinder production efficiency and increase labor and management costs for factories.

After the vibrator 41 works, it drives the feeding cylinder 3 to vibrate. After the steel balls to be tested are placed on the surface of the screening plate 43, the steel balls that meet the test size fall to the bottom plate 45 through the screen hole 44. At this time, the steel balls are sorted out. The steel balls that meet the test size are further conveyed to the testing station from the bottom discharge nozzle 46. The steel balls that do not pass through the screen hole 44 are discharged through the corresponding discharge nozzle 46 for unified recycling.

[0025] Please see Figure 3 , Figure 4The feeding assembly 5 includes a mounting frame 51 disposed on one side of the support frame 1. A fixed seat 52 is mounted on the top of the mounting frame 51. A speed-regulating motor 53 is mounted on one side of the fixed seat 52. A rotating disk 54 is rotatably mounted in the middle of the fixed seat 52. Several material dropping holes 55 are opened around the edge of the rotating disk 54. The output end of the speed-regulating motor 53 is connected to the rotating disk 54 for transmission. A bracket 56 is provided on one side of the mounting frame 51. A feeding frame 57 is mounted on the top of the bracket 56. A feeding groove 58 is opened in the middle of the feeding frame 57. One side of the rotating disk 54 corresponds to one end of the feeding groove 58. A drive pulley 6 is fixedly mounted on the output end of the speed-regulating motor 53. A transmission rod 7 is mounted on the back of the rotating disk 54. A driven pulley 8 is mounted on one end of the transmission rod 7. The drive pulley 6 and the driven pulley 8 are connected by a transmission belt 9.

[0026] In practical use: A mounting bracket 51 is installed on one side of the support frame 1, and a fixed seat 52 is installed on the top of the mounting bracket 51. A rotating disk 54 is installed in the middle of the fixed seat 52. When the speed regulating motor 53 rotates, it drives the drive pulley 6 to rotate. The drive pulley 6 drives the driven pulley 8 to rotate through the transmission belt 9. The driven pulley 8 drives the rotating disk 54 to rotate through the transmission rod 7. The sorted steel balls are conveyed through the drop hole 55 opened on the edge of the rotating disk 54. The steel balls are conveyed to the feeding rack 57 at the top of the bracket 56 through the rotating disk 54. The steel balls are conveyed to the inspection station through the feeding trough 58 in the middle of the feeding rack 57, which replaces the manual feeding method and improves production efficiency.

[0027] Please see Figure 3 The front end of the discharge nozzle 46 corresponding to the base plate 45 is provided with a storage box 10. The bottom of the storage box 10 is provided with a through hole 11, and the rotating disk 54 rotates and passes through the through hole 11.

[0028] In practical use: The front end of the discharge nozzle 46 corresponding to the base plate 45 is provided with a storage box 10. The bottom of the storage box 10 is provided with a through hole 11. The rotating disk 54 rotates and passes through the through hole 11. When the steel balls that meet the test are screened, they slide down through the discharge nozzle 46 into the storage box 10. When the rotating disk 54 passes through the through hole 11 and enters the storage box 10, the steel balls fall into the drop hole 55 on the edge of the rotating disk 54, which facilitates the conveying of the screened steel balls.

[0029] Please see Figure 1 , Figure 4 A baffle 12 is installed on the side of the feeding rack 57 near the rotating disk 54. A guide plate 13 is installed at the bottom of the baffle 12, and the guide plate 13 corresponds to the feeding trough 58.

[0030] In practical use: A baffle 12 is installed on the end of the feeding rack 57 near the rotating disk 54. The height of the baffle 12 is the same as the height of the rotating disk 54, so that the steel ball is prevented from falling from the drop hole 55 when the rotating disk 54 rotates towards the feeding rack 57. The guide plate 13 installed at the bottom of the baffle 12 corresponds to the feeding trough 58, which guides the steel ball to slide into the feeding trough 58. At the same time, the guide plate 13 provides some acceleration for the steel ball to fall. By gravity, the steel ball slides inside the feeding trough 58 to the detection and picking end.

[0031] Please see Figure 4 Proximity sensors 14 are installed at both ends of the feeding rack 57, corresponding to the feeding trough 58.

[0032] In practical use: Proximity sensors 14 are installed at both ends of the feeding rack 57 corresponding to the feeding trough 58. The proximity sensors 14 facilitate the detection of whether the steel ball has completed its passage.

[0033] Please see Figure 3 , Figure 4 The rotating disc 54, storage box 10, and baffle 12 are all made of transparent acrylic.

[0034] In practical use: the rotating disk 54, storage box 10 and baffle 12 are all made of transparent acrylic material, which makes it easy to observe whether the steel ball is stuck and facilitates troubleshooting.

[0035] A mounting frame 51 is installed on one side of the support frame 1. A fixed seat 52 is installed on the top of the mounting frame 51. A rotating disk 54 is installed in the middle of the fixed seat 52. When the speed-regulating motor 53 rotates, it drives the drive pulley 6 to rotate. The drive pulley 6 drives the driven pulley 8 to rotate through the transmission belt 9. The driven pulley 8 drives the rotating disk 54 to rotate through the transmission rod 7. The sorted steel balls are conveyed through the drop holes 55 opened on the edge of the rotating disk 54. The steel balls are conveyed to the feeding rack 57 at the top of the support 56 through the rotating disk 54. The steel balls are conveyed to the inspection station through the feeding trough 58 in the middle of the feeding rack 57, which replaces the manual feeding method and improves production efficiency.
