Abstract

The invention discloses a welding machining technology of a swinging frame. The welding machining technology of the swinging frame is characterized in that a single piece required for parts is taken for assembling welding, the assembling welding is characterized in that uniform welding is carried out at two side symmetric positions, vibration aging is carried out after welding to remove welding stress, and then, the single piece is switched to a numerical control horizontal type machining center to be machined to reach required sizes. According to the welding machining technology of the swinging frame, the welding quality and machining precision of the swinging frame are effectively improved, welding deformation of the parts can be effectively reduced in the welding and machining process of tool positioning, meanwhile, the technology application of the vibration aging can effectively reduce the welding stress, numerical control machining can further guarantee the machining precision and improve the machining efficiency, ensure the safe using performance of the whole manufacturing process of the swinging frame, and guarantee the safety of the engineer operation.
