Side edge groove milling device for robot joint machining

A side edge groove milling device for robot joint machining comprises a clamping structure and a groove milling structure assembly. The clamping structure comprises a vertical moving structure, a first rotating structure and a pressing structure; the groove milling structure assembly comprises a first horizontal moving structure, a second horizontal moving structure, a second rotating structure and a groove milling structure. The robot joint part needing side edge groove milling machining is fixed through the first rotating structure and the pressing structure of the clamping structure, and the first rotating structure and the vertical moving structure automatically adjust the groove milling face and the groove milling position. According to the groove milling structure, the groove milling position and angle are determined through a first horizontal moving structure, a second horizontal moving structure and a second rotating structure of the groove milling structure assembly, all the structures cooperate, sid
