Based on the precision requirements of needle roller bushings, needle roller bearing ring sorting machines have emerged. This equipment uses a detection device to sort qualified parts by ring size to ensure tolerance consistency, thereby optimizing the overall reliability and service life of the bearing.

[0052] Working principle: First, the workpiece 11 in the loading box 701, pushed by other workpieces 11 inside the loading box 701, enters the surface of the conveyor belt 502. The conveyor belt 502 moves the workpiece 11 to the loading platform area. Then, driven by the first shifting cylinder 3071 and the second shifting cylinder 3072, the shifting plate 304 moves the workpiece 11 to the rear station one position. When the workpiece 11 moves to the fourth station, the roller detector 303 moves downward under the action of the pushing cylinder 302 until it is inserted into the workpiece. Inside part 11, the cylinder 302 extends its output end, causing the two ends of the roller detector 303 to press against the inner wall of part 11 respectively. The stroke detector 301 captures the stroke data of the cylinder 302 and judges the inner diameter error of part 11 accordingly. Then, it sends a signal to the servo motor 903, which drives the discharge pipe 902 to rotate above the corresponding discharge box 901. After the switching plate 304 moves the detected part 11 to the discharge port 306, the part 11 falls into the designated discharge box 901.

[0053] Furthermore, the outer wall of the fixed column 1001 is connected to the first spring 1003, and the outer wall of the fixed column 1001 is movably disposed within the inner wall of the limiting plate 1002. The linkage between the fixed column 1001, the first spring 1003, and the limiting plate 1002 sets the position boundary for the workpiece 11 in the lateral movement direction. The first fixing button 1004 controls the range of motion of the fixed column 1001, and the inner wall of the first fixing button 1004 maintains sliding contact with the sliding column 1005. A friction strip 1007 is attached to the bottom surface of the outer wall of the limiting plate 1002. The friction strip 1007 enhances the lateral position limiting effect of the device and provides more... In a stable limiting state, the outer wall of the slide column 1005 is provided with a second spring 1006 and a second fixing button 1009 to constrain the longitudinal displacement of the slide column 1005 and prevent it from exceeding the predetermined range of motion. The inner wall of the second fixing button 1009 is fastened to the top area of ​​the outer wall of the slide column 1005, and the bottom of the outer wall of the slide column 1005 is tightly connected to the pressure strip 1008.
