Description

Technical Field

[0001] The utility model relates to the technical field of forklift oil tank assembly welding, in particular to an integrated tooling for forklift oil tank correction assembly welding. Background Art

[0002] In the forklift industry, for some forklift models produced in large quantities, before welding the fuel tank, it is necessary to first manufacture the mold for welding the fuel tank, and then use the mold to weld the fuel tank, so as to improve the actual welding efficiency. At present, some fuel tanks are mainly composed of four parts: outer wall plate, sealing plate, counterweight mounting plate and inner wall plate. During actual welding, since the fuel tank needs to form a closed box, the welding gap between the four plates should not be too large (within 3mm) when welding, so it is necessary to clamp and position the four plates before welding. In addition, when the outer wall plates are bent and formed in batches, the bending size is often inconsistent with the design size. The bending part of the bent outer wall plate is offset to the outside, and the bending angle is greater than 90°. When welding, the bending edge needs to be corrected before welding. If the on-site manual welding is not performed with welding tools, the operation will be very cumbersome, labor-intensive, and will affect the production efficiency and product quality of the subsequent processes.
