Automatic welding device for shear stud of bridge steel structure

Abstract

This invention relates to the technical field of shear stud welding, specifically to an automatic shear stud welding device for bridge steel structures. The device includes: a secondary support mechanism; a main support mechanism slidably mounted on the secondary support mechanism, capable of forward and backward movement through alternating support and relative sliding; a main beam rotatably mounted on the main support mechanism, also capable of forward and backward movement; a shear stud feeding mechanism located on one side of the main beam; a magnetic ring feeding mechanism slidably mounted on the other side of the main beam; and a welding mechanism rotatably located at the front of the main beam, including a shear stud holder for clamping the shear studs to be welded and a clamping plate for holding the magnetic ring fitted onto the shear studs. The position of the shear studs held by the shear stud holder can be adjusted by the forward and backward movement and rotation of the main beam relative to the main support mechanism. This invention achieves automatic feeding of shear studs and magnetic rings, automatically welding the shear studs to the designated positions on the bridge steel structure, saving manual welding work, and improving welding efficiency and quality.
