An automatic drilling and milling
machine for a chain connecting pin shaft is mounted on a rack table face, the automatic drilling and milling
machine comprises a vibration disc, a feeding guide rail, an air cylinder, clamping jigs, a flat table milling mechanism, a central hole drilling mechanism, a
small hole drilling mechanism, a chamfering mechanism, an octagonal eight-
station rotating disc, a precise
cam indexer, an
electric motor and an automatic drilling and milling
machine body support. The octagonal eight-
station rotating disc is arranged on the front side of the automatic drilling and milling machine body support, the precise
cam indexer is arranged behind the octagonal eight-
station rotating disc, the
electric motor is arranged on the rear side of the automatic drilling and milling machine body support, the
electric motor is provided with a
compressed air flow divider, the vibration disc is arranged on one side of the octagonal eight-station rotating disc, the eight clamping jigs are mounted on the octagonal eight-station rotating disc, the flat table milling mechanism, the central hole drilling mechanism and the
small hole drilling mechanism are arranged on the upper side of the octagonal eight-station rotating disc, and the chamfering mechanism is mounted on the front side of the octagonal eight-station rotating disc. According to the technology, the full-automatic production process of part
machining is achieved, and production efficiency and product quality are improved greatly.
