Abstract

The invention relates to a thin-wall face gear machining fixture, comprising a fixture body, an axial locking screw, a pressing plate and a positioning screw, wherein one end of the fixture body is provided with a boss which can be arranged in the centre bore of a workbench and the other end of the fixture body is provided with an annular boss which is used for installing a thin-wall face gear; the annular boss is provided with the pressing plate and the axial locking screw which are used for fixing the thin-wall face gear; the periphery of the fixture body is provided with through grooves; the center of the fixture body is provided with a gauging spindle which is coaxial with the fixture body; the boss of the fixture body, which is arranged in the centre bore of the workbench, can be also arranged on an adjustable mandrel; and the adjustable mandrel is arranged on the fixture body by the positioning screw. The thin-wall face gear machining fixture of the invention can be used for neutralizing forced deformation of a part to be processed in the machining process, has compact structure, is convenient to assemble and disassemble, and can ensure that the forced influences on the gear shaping, gear hobbing, gear grinding and the like of the thin-wall face gear in the machining process can be overcome; and meanwhile, the thin-wall face gear machining fixture of the invention can be applied in the machining process of the other types of thin-wall parts.

Description

technical field [0001] The invention relates to a processing fixture, in particular to a thin-wall gear processing fixture. Background technique [0002] Face gear drive (Face Gear Drive) is a gear transmission in which cylindrical gears and conical gears mesh, because of its small size, light weight, high load capacity, low noise, high reliability, long life, etc. It is widely used in power splitting of aviation main reducer, milling machine spindle, differential gear train on automobile, transmission of robot joints, precision transmission with small backlash and new energy transmission system. [0003] At present, foreign technical data show that face gears can be processed by gear shaping, hobbing and grinding. Due to the strict secrecy of foreign face gear processing technology, the face gear processing technology has not been fully mastered in China, and only carried out Research on face gear shaping technology. [0004] During the processing of thin-walled gears, du...
