The invention relates to the technical field of boring cutting machining, in particular to a boring cutter for machining an inner hole of an elbow within 180 degrees. A cutter with a 95 degree arc-shaped appearance is adopted to machine, and the machining quality and the machining precision are ensured. The boring cutter for machining the inner hole of the elbow within 180 degrees comprises a hollow cylinder arc-shaped cutter bar, and the hollow cylinder arc-shaped cutter bar is in a 95 degree circular arc shape; cardan joint fixing plates are correspondingly arranged at the middle and the twoends of the hollow cylinder arc-shaped cutter bar, and a through hole is formed in the middle cardan joint fixing plate; a plurality of cardan joints connected in series are arranged in the hollow cylinder arc-shaped cutter bar, and the multiple cardan joints are separated through the middle cardan joint fixing plate and are symmetrically arranged; the cardan joints positioned on the two sides ofthe middle cardan joint fixing plate are connected through connecting pieces arranged in the through hole, the cardan joints positioned at the two ends stretch out of the two ends of the hollow cylinder arc-shaped cutter bar, a telescopic boring cutter blade is arranged at one end through a cutter frame, and a main shaft connecting shank is connected to the other end.
Description
technical field [0001] The invention relates to the technical field of boring processing, in particular to a boring tool for processing the inner hole of an elbow within 180°. Background technique [0002] With the development of technologies such as aerospace, robotics, new energy, precision machinery, and national defense technology, the requirements for the accuracy, strength, quality, life, and stability of parts are constantly increasing. With the improvement of precision and complexity of machinery, the progress of machinery manufacturing industry and the rapid development of domestic heavy industry and light industry, the application range of curved pipes and regular curved holes is also expanding. Due to the application of curved pipes in precision instruments such as aerospace, nuclear energy, high-precision instruments, and engines, the requirements for their accuracy continue to increase. [0003] For the processing plan of the inner hole of the elbow, a CNC mach...
