AI Technical Summary

Technical Problem

In the existing technology, during the positioning and clamping spot welding process of steel panels and U-ribs, the assembly gap between the U-ribs and the panels is too large, which leads to a decrease in welding quality, and the traditional operation method may damage the panels.

Method used

The production line adopts a stepping mobile assembly machine. Through the stepping plate unit feeding device and the gantry rib plate assembly machine, the steel panel and multiple rib plates are positioned, pressed and spot-welded. Multiple sets of positioning and pressing devices operate synchronously to avoid the deformation risk caused by individual spot welding.

Benefits of technology

It realizes automated feeding, positioning, clamping and unloading of plate units, improves the positional accuracy of ribs before full welding, reduces deformation and avoids damage caused by traditional methods.

Abstract

The application discloses a plate unit step-by-step moving assembly machine production line and process, relates to the plate unit welding assembly technical field, and is characterized in that multiple fixed welding points are arranged at equal intervals in the rib plate direction, each row of fixed welding points forms a step-by-step assembly position, and the production line comprises a step-by-step plate unit feeding device, a gantry type rib plate assembly machine and a step-by-step plate unit discharging device.The step-by-step plate unit discharging device adopts the same step-by-step action as the step-by-step plate unit feeding device, and the step-by-step action realizes the discharging action of the to-be-assembled plate unit that is positioned, pressed and fixed by spot welding.The application realizes the automatic plate unit feeding except the spot welding action, the positioning, pressing and discharging actions, and the crane support is not needed in the plate unit step-by-step moving assembly machine production line area, positioning and pressing are performed on each row of fixed welding points forming the step-by-step assembly position each time, and the deformation risk caused by the positioning and pressing on a single position is avoided.
