Thrust needle roller bearing cage feeding device and automatic needle-assembling machine

The invention discloses a thrust needle roller bearing cage feeding device and an automatic needle-assembling machine and belongs to the field of needle roller bearing assembling equipment. The thrustneedle roller bearing cage feeding device comprises a storage hopper for vibrating feeding. A first conveying channel is formed in the inner wall of the storage hopper. A spirally-arranged second conveying channel is formed on the inner wall position close to the top of the storage hopper. The second conveying channel is obliquely arranged. The dip angle of the second conveying channel presents agradual-increasing trend along the direction away from the first conveying channel. A discharging port is formed in the end, away from the first conveying channel, of the second conveying channel. Ascreening segment is formed in the position, close to the discharging port, in the second conveying channel. A resistant strip is arranged on the side, facing the center of the storage hopper, of thescreening segment in an exte
