Steel plate welding end positioning mechanism

Abstract

The invention relates to a steel plate welding end positioning mechanism which comprises two positioning assemblies symmetrically arranged in a face-to-face manner. Each positioning assembly comprises a hydraulic oil cylinder, an oil cylinder installation base, a swing arm installation base and a positioning swing arm, wherein the swing arm installation base is fixed to a transverse beam of welding equipment during installation, the tail end of the positioning swing arm is hinged to the swing arm installation base, the top of the positioning swing arm is provided with a hinge support, the oil cylinder installation base is arranged behind the swing arm installation base, the oil cylinder installation base is fixed to the transverse beam of the welding equipment during installation, a cylinder body of the hydraulic oil cylinder is hinged to the oil cylinder installation base through a pin shaft, the piston rod end of the hydraulic oil cylinder is hinged to the hinge support of the top of the positioning swing arm, and a piston rod of the hydraulic oil cylinder stretches out and retracts back to drive the front end of the positioning swing arm to ascend or descend. By means of the steel plate welding end positioning mechanism, the plate edges of conveyed steel plates can be automatically positioned to the welding center positions before steel plate welding; and meanwhile, steel plate seams can be parallel to a welding gun running track, the steel plate welding quality is guaranteed, and the equipment automation degree is improved.

Description

technical field [0001] The invention relates to a positioning mechanism for tailor welding ends of steel plates, which belongs to the technical field of mechanical equipment. Background technique [0002] At present, during tailor welding of steel plates, the seams of the two steel plates that are transported in are basically not parallel to the trajectory of the welding torch, and the deviation is large, which requires manual adjustment, resulting in low production efficiency and difficulty in improving the automation of the equipment. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a steel plate tailor welding end positioning mechanism, which has a simple, compact, reasonable structure, convenient operation, can ensure the quality of steel plate tailor welding, and improve the automation of equipment. [0004] According to the technical solution provided by the present invention: the po...
