Automatic feeding device for small bearings

Abstract

The invention discloses an automatic feeding device for small bearings. The automatic feeding device comprises a frame body, a bearing storage bin, a limiting stopping mechanism, a driving connectingrod mechanism and a bearing transferring rail, the storage bin is arranged on the frame body, and the limiting stopping mechanism, the driving connecting rod mechanism and the bearing transferring rail are sequentially arranged above the storage bin from top to bottom and are coordinated with one another for transferring. The automatic feeding device has the advantages that bearings can be first orderly placed in the bearing storage bin in multiple rows and multiple columns through a mechanical arm or manual work, multi-batch feeding at a time used for automatic rotor assembly of one shift ormultiple shifts is realized, the bearings slide along a slope of the storage bin for feeding through the gravity of the bearings, the gravity of the bearings is fully utilized for generating movementkinetic energy, short-distance movement of the whole row of bearings is realized, and therefore a complex transferring structure is removed, and the feeding procedure is simplified.

Description

technical field [0001] The invention relates to the technical field of automatic production of motor rotors, in particular to an automatic feeding device for small bearings. Background technique [0002] We know that for small motors with low noise and high efficiency (such as air conditioner motors, purifier motors, etc.), two high-precision, ultra-quiet small deep groove ball bearings are generally used at both ends of the rotor. Usually this kind of bearings are relatively "delicate" and fine. A slightly larger vibration or collision may cause damage to the bearing channel, resulting in poor bearing sound. When the rotor rotates at a high speed, this bearing abnormal sound will be amplified, and the motor will produce Very loud noise. Therefore, the conventional automatic feeding device for small parts, such as the combination of vibrating plate and linear feeder, cannot be used for this type of bearing. This problem has been plaguing the motor industry. In the prior ar...

AI Technical Summary

Problems solved by technology

Usually this kind of bearings are relatively "delicate" and fine. A slightly larger vibration or collision may cause damage to the bearing channel, resulting in poor bearing sound. When the rotor rotates at a high speed, this bearing abnormal sound will be amplified, and the motor will produce very loud noise

Therefore, the conventional automatic feeding device for small parts, such as the combination of vibrating plate and linear feeder, cannot be applied to this type of bearing.

This problem has been plaguing the motor industry for a long time. In the existing technology, materials can only be manually loaded one by one into the pre-loading bin of the rotor press-fitting fixture to realize the bearing assembly of the rotor, and the production efficiency is very low.
