Automatic steel ball assembling-in device

The invention relates to the technical field of machining, in particular to an automatic steel ball assembling-in device. A base, a storage box, a conveying channel, a transmission assembly for controlling steel ball assembling-in and at least two stop assemblies are included. The storage box, the conveying channel and the stop assemblies are all arranged on the base. The storage box is provided with a through hole communicating with the conveying channel. The start end side of the conveying channel is provided with an elevating assembly which can elevate steel balls in the storage box to be flush with the through hole. The tail end side of the conveying channel is provided with a guiding-in block for guiding the steel balls towards the steel ball support. The vertical height of the startend of the conveying channel is larger than that of the tail end of the conveying channel. An inner supporting claw capable of achieving rotating, opening, closing and extruding of the steel balls into cavities under the acti
