The invention relates to an automatic feeding mechanism of a boring plane tool arm. The automatic feeding mechanism includes a boring rod, a boring rod lead screw arranged on the boring rod, a first tool rest, a second tool rest, a transmission key, a tool arm body and a sliding block, the first tool rest and the second tool rest are installed on the surface of the boring rod through bolts, the first tool rest and the second tool rest are fixedly connected with the boring rod through the transmission key, the tool arm body is fixedly connected with the second tool rest, and the sliding block is slidably connected with the tool arm body; and the sliding block is provided with a tool groove, a tool groove cover plate and a sliding block nut, the tool groove cover plate is connected with thesliding block in a threaded mode, a transmission chain is arranged between the sliding block and the boring rod, and the transmission chain is connected with the boring rod lead screw and the slidingblock nut. According to the feeding mechanism, the first tool rest is fixed to the boring rod through the transmission key, and the boring rod can be well protected; wear of gears and other transmission parts is effectively avoided, and the service life is prolonged; and installation is simple, the time and labor are saved, construction is convenient, rotation of the boring rod lead screw is converted into feeding motion of the sliding block, speed control gear boxes are not required to be additionally installed on the tool rests, materials are saved, and potential safety hazards are also eliminated.
Description
technical field [0001] The invention relates to the technical field of boring, in particular to an automatic feeding mechanism of a boring plane cutter arm. Background technique [0002] Shafting and rudder systems are important components of a ship's power system, and require high installation accuracy. Boring is often required before shafting and rudder installation. Mining machinery, hydropower, nuclear power, steam turbines and other equipment that cannot be disassembled on site often need to be bored. When boring a hole, it is necessary to bore the plane, first process the inner hole, and then bore the plane. Generally, when boring a hole, the axial feed of the tool is realized through the cooperative movement of the screw provided on the boring bar and the semicircle nut provided on the tool holder, and the semicircle nut is fixedly connected with the tool holder. The feed gearbox of the boring hole controls the rotation of the screw, and the screw can push the tool...
