[0002] In order to facilitate the subsequent clamping and assembly of shaft parts, it is necessary to open a center hole at the end of the shaft parts as a process hole. During subsequent lathe processing, one end of the shaft can be clamped with a three-jaw chuck, and the process hole at the other end can be supported with a thimble to install the shaft. This requires a device for processing the center hole.

Through the above-mentioned method, the horizontal drilling machine with an automatic feeding device described in the utility model uses a conveyor chain to convey the round bar material to be processed to the bottom of the semicircular upper fixing seat, and after the telescopic device is extended, the semicircular upper fixing seat and the semicircular lower positioning seat wrap the bar material, and the drilling device performs processing, which is flexible to operate, has high work efficiency and good safety.

[0043] When the conveying shaft is transported, the shaft stored on the unloading rack 41 moves along the direction of the guide plate 412 by its own weight until the shaft falls onto the conveying rack, and the shaft rolls on the top of the conveying rack until the shaft hits the limiting member 5 to reach the flipping station, and the rotating motor 443 is started by the controller 35 to rotate the flipping block 442 to drive the shaft to move, and the shaft moves on the inclined portion 51 until it passes the highest point of the inclined portion 51, and then the shaft rolls along the guide portion 52 onto the material transfer wheel 431, and the material transfer motor 432 is started to make several material transfer wheels 431 rotate synchronously, and the shaft moves until the end of the shaft hits the baffle 31.
