Lap welding tooling suitable for excavator arm lugs

Abstract

The invention discloses an overlap-welding tool suitable for lug plates of an excavator bucket rod. The overlap-welding tool comprises a welding base, a front supporting and positioning device for positioning a front supporting assembly of the excavator bucket rod, a rear supporting and positioning device for positioning a rear supporting assembly of the excavator bucket rod, a first lug plate positioning device for positioning a first lug plate and a second lug plate positioning device for positioning a second lug plate; and the rear supporting and positioning device, the first lug plate positioning device and the second lug plate positioning device are movably arranged on the welding base. According to the overlap-welding tool suitable for the lug plates of the excavator bucket rod disclosed by the invention, the excavator bucket rod and the lug plates are accurately positioned and fixed through each positioning device arranged on the base, and welding assembly is carried out, so that production efficiency is high, product quality is stable, a rejection rate is low, and requirements on skill of welding workers are reduced much, and therefore, the overlap-welding tool is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery processing equipment, in particular, the invention relates to a lap welding tool suitable for the lug plate of the arm of an excavator. Background technique [0002] The bucket rod of the excavator is a welding assembly.
