Coaxial temperature control track follow-up laser heating auxiliary cutting device

The invention provides a coaxial temperature control track follow-up laser heating auxiliary cutting device. The coaxial temperature control track follow-up laser heating auxiliary cutting device comprises a machine tool spindle frame, a clamp and an output head. The machine tool spindle frame is a machine tool static part, and a cutter is installed below the machine tool spindle frame and driven by a machine tool spindle to rotate. The clamp comprises a supporting plate, a left clamping plate, a right clamping plate and a bracket, wherein a motor, a speed reducer and a bearing are fixed to the machine tool spindle frame through the supporting plate. A small gear is installed on an output shaft of the speed reducer, an inner ring of the bearing is in interference fit with the bracket, and an outer ring of the bearing is in interference fit with a large gear. The output head is arranged on the hanging plate, the hanging plate is assembled on the large gear, and the motor drives the small gear to be meshed with
