The invention relates to a
laser transmission
welding clamping apparatus used between
thermoplastic plastics or between a
thermoplastic plastic and a
metal material and capable of achieving any curved surface
welding. The
laser transmission
welding clamping apparatus comprises a PC
machine, a PLC controller, a hydraulic
system, a
pressure sensor and a
light source control system, and further comprises a pressure applying
system, a pressing component and a periphery fixation member, wherein the pressure applying
system applies uniform pressing force on the surface of the two-dimensional pressing component, the pressing component transmits the pressing force to the upper work-piece and the lower work-piece and the pressing force is uniformly distributed so as to achieve the clamping on the complex work-piece, and
laser performs the welding on the work-piece under the control of the PC
machine. According to the present invention, with the
laser transmission welding clamping apparatus of the
thermoplastic plastic, the welding on the any curved surface work-piece can be achieved, the welding path and the pressing force can be precisely controlled, the whole strength and the stiffness of the welded member can be increased, the pressing of the upper mold and the lower mold is adopted, the pressing force is uniformly distributed on the surface, the
stress concentration after
processing is voided, and the quality of the processed work-piece is improved.
