The invention discloses a numerical control friction stir welding machine, and relates to the technical field of numerical control equipment. The numerical control friction stir welding machine comprises a frame type gantry structure, a spindle tilting device, a spindle slewer, a slewing driving device, a spindle and a control device; a mixing needle is arranged at the bottom of the spindle; the spindle tilting device and the spindle slewer are arranged on the spindle; the spindle slewer is in transmission connection with the slewing driving device; and the spindle slewer and the slewing driving device are electrically connected with the control device. In a welding process, the position, in the current spindle axis direction, of the mixing needle can be adjusted in real time; before welding, the off-centering quantity of the mixing needle is set, and the control device may automatically adjust the slewing speed and the angle in the welding process to make sure that the mixing needle is inclined in the movement tangential direction all the time; a machining programming procedure in operation process and a triaxial machining center procedure are identical, thus no fourth-axis procedure is added; and an operating method of the numerical control friction stir welding machine and that of an ordinary triaxial machining center are identical, thus the operation is convenient.
Description
technical field [0001] The invention relates to the technical field of numerical control equipment, in particular to a numerical control friction stir welding machine. Background technique [0002] Friction welding is a method of using the heat generated by the mutual movement and friction of the workpiece ends to make the ends reach a thermoplastic state, and then quickly upset to complete the welding. Friction welding can easily join the same or dissimilar materials, including metals, some metal matrix composites, ceramics and plastics. [0003] The friction stir welding method is the same as conventional friction welding. Friction stir welding also uses friction heat and plastic deformation heat as the welding heat source. The difference is that the welding process of friction stir welding is that a cylinder or other shape (such as a threaded cylinder) is inserted into the joint of the workpiece. Through the high-speed rotation of the welding head, it rubs against the m...
