Internal reinforcing rib assembling mechanism for mechanical arm or box beam of engineering machinery

Abstract

The invention discloses an internal reinforcing rib assembling mechanism for a mechanical arm or a box beam of engineering machinery. The mechanism comprises a main rack and a secondary rack, whereinthe rear bottom surface of a top plate of the main rack is tightly attached to the top surface of the middle of the front part of a top plate of the secondary rack; a plurality of rib plate conveyinggroove bodies extending backwards are fixed to the top surface of the top plate of the main rack; a front limiting plate and a rear limiting plate are fixed to the top surface of the middle of the topplate of the secondary rack, and a bottom through groove is formed between the front limiting plate and the rear limiting plate; and an upper supporting frame is fixed on the top plate of the main rack. According to the internal reinforcing rib assembling mechanism for the mechanical arm or the box beam of the engineering machinery, reinforcing rib plates placed on the rib plate conveying groovebodies can be automatically grabbed and movably pressed against a bottom plate to be welded for assembling, so that subsequent manual or mechanical continuous welding is facilitated, the internal reinforcing rib assembling mechanism improves the welding efficiency greatly, the single-hand material taking and supporting of a welder is not needed, and the manual labor amount is greatly reduced.

Description

Technical field [0001] The present invention relates to the technical field of engineering machinery manufacturing equipment, and more specifically to a mechanism for assembling internal reinforcement ribs of a mechanical arm or a box beam of an engineering machinery. Background technique [0002] Many mechanical arms or box beams are used in existing construction machinery, and the mechanical arms or box beams are generally welded and fixed with multiple side plates and internal reinforcement plates; [0003] In production, it is generally to place the bottom plate of the box body that needs to be welded on the ground, and then place the stiffener plates on the bottom plate one by one for welding. It needs to manually take the stiffener plates one by one and then weld them. It is necessary to support the stiffener plate with one hand, and fix it by spot welding with the other hand. Then, complete welding is performed. The efficiency is low and the effect is poor. Moreover, since t...

[0003] When making, it generally places the bottom plate of the box body that needs to be welded on the ground, and then places the stiffener plates on the bottom plate one by one for welding. It needs to manually take the stiffener plates one by one and weld them again. It is necessary to support the stiffener plate with one hand, fix it by spot welding with the other hand, and then carry out complete welding, which has low efficiency and poor effect, and because welding is generally performed by squatting on the ground manually, the energy consumption of taking materials and welding is even greater. Large, the amount of manual labor is quite large
