20120248673POINT-WELDING CLAMP - A point-welding clamp for tightly clamping and locating different plate-shaped metal pieces to be welded together. The point-welding clamp includes a clamp section for clamping the plate-shaped metal pieces to be welded together, a drive section for controlling the clamping force applied to the plate-shaped metal pieces by the clamp section, and an abutment section including two abutment bodies. The abutment bodies are pivotally connected with the clamp section in abutment with the plate-shaped metal pieces. Each abutment body has an engagement face. The engagement faces of the abutment bodies serve to attach to the surfaces of the plate-shaped metal pieces to keep the force applied to the plate-shaped metal pieces by the clamp section normal to the surfaces of the plate-shaped metal pieces. Accordingly, it is ensured that the plate-shaped metal pieces are securely clamped by means of the point-welding clamp.10-04-2012

20130300048Smooth Disengagement with Quick Clamping Mechanism - A Smooth Disengagement with Quick Clamping Mechanism designed for increasing efficiency and improving the quality of clamping systems that can be used in various vises, C-clamps and all other clamping applications. This invention applies a concept of using two sets of opposing thread angles; one thread set is used at engagement, while the other is used at clamping. By using these two sets of opposing helix angles it creates opposing axial forces against each other, so as to force the clamping thread set to rotate first in the process of releasing a clamping force. This function would prevent a sudden drop in clamping force; a problem most quick clamping designs having in the industry.11-14-2013
