Butt welding tool for C-shaped beam of port stacking machine

Abstract

The invention discloses a butt welding tool for a C-shaped beam of a port stacking machine. The butt welding tool comprises a platform, wherein a plurality of positioning and clamping devices are arranged on the platform and distributed in a line-shaped array. Each of the positioning and clamping devices is composed of a reference block, a limit seat positioned on one side of the reference block, a first locking mechanism positioned on the other side of the reference block and a second locking mechanism positioned above the reference block. The reference block is movably arranged between two lateral plates of the C-shaped beam, the width of the reference block is matched with the size of a crotch opening position of the C-shaped beam, and the distance between the limit seat and the reference block is matched with the thickness of each of the lateral plates of the C-shaped beam. The butt welding tool for the C-shaped beam of the port stacking machine has the advantages that the size control accuracy is high, the straightness accuracy of the manufactured C-shaped beam is good, extra mechanical machining is not required, production cost is saved to a large extent, and mechanical performance of the C-shaped beam is ensured.

Description

technical field [0001] The invention relates to the technical field of a port stacker, in particular to a C-beam tailor welding tool for a port stacker. Background technique [0002] A port stacker is a vehicle that stacks empty containers at ports and terminals, and is a logistics vehicle. Among them, the C-beam in the mast assembly of the port stacker is used as the upper and lower running track of the mast of the stacker. The quality of its production directly affects the movement track of the mast. Therefore, its dimensional accuracy is high, and it is necessary to ensure the welding of the C-beam. The final straightness prevents bending deformation. The C-shaped beam is a C-shaped combination of three surfaces, specifically including two side plates and a transverse plate connecting the two side plates. Due to the long length of the C-beam used on the port stacker, it is usually necessary to combine multiple side plates and transverse plates to meet the length require...
