Description

Push pin feeding device of high-speed needle roller sorting machine Technical Field The utility model relates to the technical field of sorting, in particular to a push pin feeding device of a high-speed needle roller sorting machine. Background In the production and sorting process of the needle rollers, the efficiency and the precision of the feeding link directly influence the efficiency and the quality of the whole sorting process, and the needle rollers are used as core components of the high-precision bearing, so that the requirements on the size consistency and the surface quality are extremely high, and the feeding device needs to ensure that the needle rollers enter a sorting station in a stable, ordered and damage-free mode. Push pin loading attachment generally includes vibration dish feeding system, sharp pay-off track, divides material/fender needle mechanism, push pin mechanism, and current loading attachment most devices rely on vibration dish directional sequencing, but the high draw ratio (long and thin cylindrical) of kingpin easily takes place to overlap, alternately or the gesture mistake in vibration transportation, need adjust many times, leads to the feed beat delay, and the feed is unsmoothly, in addition, cylinder thrust fluctuation (when atmospheric pressure is unstable), can lead to push pin not put in place or overshoot to cause separation efficiency low, can't satisfy high-speed production's demand. Therefore, aiming at the problems that the existing feeding device is easy to overlap, cross or have wrong posture in vibration conveying, multiple adjustments are needed, the feeding beat is delayed, the feeding is not smooth, in addition, the push pin cannot be in place or overshoot due to the fluctuation of the thrust of the cylinder, the push pin feeding device of the high-speed needle roller sorting machine can be designed, the feeding speed and the feeding stability are improved, the needle clamping phenomenon is reduced, and the maintenance cost and the failure rate are reduced. Disclosure of utility model In order to overcome the problems that the existing feeding device is easy to overlap, cross or have wrong postures in vibration conveying, the feeding beat is delayed and the feeding is not smooth due to multiple times of adjustment, and in addition, the push pin is not in place or overshot due to the fluctuation of the thrust of the cylinder.
