Device for boring, cutting and feeding tail shaft hole of ship

Abstract

The invention discloses a device for boring, cutting and feeding a tail shaft hole of a ship, which belongs to the field of ship machines. The device comprises a screw rod gear, a transition bracket, a connecting screw, a feeding engine seat, a crank, a hand automatic feeding mechanism and a quick cutter presetting mechanism, wherein the transition bracket is arranged in coordination with a boring center hole through a hole below the transition bracket and is arranged together with the feeding engine seat through the connecting screw; the hand automatic feeding mechanism and the quick cutter presetting mechanism are engaged with each other through a gear and are arranged in a mounting hole of the feeding engine seat; the screw rod gear is matched with an output gear on the quick cutter presetting mechanism; and the crank is arranged at one end of a gear shaft of the hand automatic feeding mechanism or the quick cutter presetting mechanism, so that a cutter can be preset manually. The device is arranged on one end face of a boring shaft, and the crank is arranged on a corresponding gear shaft, so that the cutter can be quickly preset and the device can be quickly and finely turned in advance through a differential principle before machining; and after a motor is started to automatically feed the cutter, cutting and feeding amount can be changed through a shift gear in the midway, so that the tail shaft hole is stably machined, and the device has high efficiency and high accuracy.

Description

technical field [0001] The invention relates to a boring and cutting feeding device, in particular to a boring and cutting feeding device for a ship stern shaft hole, which belongs to the field of ship machinery. Background technique [0002] At present, the feed device used for boring and cutting of the tail shaft hole of the ship cannot be processed on a general-purpose boring machine due to the long tail shaft hole and large diameter. Now basically it does not have a manual tool setting function, and it cannot be quickly processed. The tool feed and fine-tuning are directly connected to the motor, and the safety is not high. The cutting feed cannot be changed during the machining process, and mechanical failures often occur, so it brings great difficulties to the machining of the tail shaft hole, and The volume is huge, and it takes time and effort to disassemble and assemble. It is currently a problem that needs to be solved urgently. Contents of the invention [0003...
