Harmonic four -axis

The utility model relates to a harmonic four -axis, the servo motor of order setting around pressing including the casing and in the casing, harmonic speed reducer machine, ring flange subassembly, servo motor include a main shaft, and the quick -witted input shaft of harmonic speed reducer is connected with the main shaft, and the output shaft of harmonic speed reducer machine is connected with the ring flange subassembly, and the ring flange subassembly includes the ring flange, have a middle quick change structure that has the check lock lever in the middle of of installing of last surfacegrooves of passing through the lid that the fastener is connected, lid above the ring flange. This harmonic four -axis during the production and processing, can keep zero point unchangeable through installation quick change structure on the ring flange, and the support time among the machining that has significantly reduced has improved production efficiency, has improved economic benefits. 本实用新型涉及种谐波四轴，包括壳体以及在壳体内按前后顺序设置的
