The invention relates to the technical field of
drilling machines, in particular to an efficient treatment type drilling
machine for
machining crane parts, which comprises a supporting base, a
drill bit is mounted at the top end of the supporting base, an alignment device is fixedly mounted at the bottom end of the
drill bit, and a transmission part is fixedly mounted at the top end of the supporting base and is positioned below the
drill bit; the alignment device comprises a vertical rod and first racks, the first racks are symmetrically and fixedly installed at the bottom end of the vertical rod, the transmission part comprises a feeding device, a receiving device and a
synchronizing device, the receiving device is fixedly installed in the center of the top end of the
synchronizing device, and the feeding device is fixedly installed at the top of the side end of the
synchronizing device; the feeding device comprises a storage cavity, a to-be-machined part, a push plate, a blocking plate, a base rod, a first spring, a first connecting
rope, a driving motor, a shaft rod, a first gear, a second gear and a third gear. Due to the arrangement of the alignment device and the transmission part, the aim of integrating constant-speed feeding and chipping synchronization flow guide when the drilling
machine is used is achieved.
