Abstract

The invention belongs to the technical field of welding clamps, and particularly relates to an H-type steel welding clamping clamp. The H-type steel welding clamping clamp comprises a base, a two-sidecentering clamping mechanism and a two-end clamping overturning mechanism; the two-side centering clamping mechanism and the two-end clamping overturning mechanism are arranged on the base; the two-end clamping overturning mechanism can clamp the two ends of a middle steel plate and fixes the middle steel plate onto the base; the two-side centering clamping mechanism can center two steel plates simultaneously to the middle steel plate located on the base for welding machining to form H-type steel; and after one side of the H-type steel is welded and machined, the two-end clamping overturningmechanism can overturn the middle steel plate by 180 degrees for machining the other side of the H-type steel. According to the H-type steel welding clamping clamp, the three steel plates can be clamped and centered and make contact quickly, and the inclination angle is adjusted to facilitate gathering of a submerged arc welding agent for welding.

Description

technical field [0001] The invention belongs to the technical field of welding fixtures, in particular to an H-shaped steel welding fixture. Background technique [0002] H-shaped steel is an economical cross-section high-efficiency profile with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used. At present, H-shaped steel mainly uses submerged arc welding to weld three steel plates together. During welding, it is difficult to accurately center and clamp the three steel plates, and for small-batch production or when a small amount of H-shaped steel needs to be temporarily welded for strength testing, it is used. The ...
