Abstract
A kind of automotive front crossbeam assembly welding procedure is put into part frame to be welded, then carry out sequence welding it is characterized in that first drying up each component to be welded with compressed air.Weldment shape and size consistency is good, and product qualification rate is high, and production automation degree is high, and welding quality is good, and labor intensity of workers is low, and working environment is good, high production efficiency, at low cost, has application value.
Description
Technical field
The present invention relates to a kind of auto parts welding procedure, especially a kind of automotive front crossbeam assembly welding procedure.
Background technique
Currently, mostly using simple tooling, human weld, workpiece dress greatly in the production process of SUV vehicle front beam assembly
Press from both sides cumbersome, complicated for operation, the shape and size consistency of weldment is poor, poor welding quality, influences the intensity and safety of weldment
Performance, production efficiency are low, at high cost.
Summary of the invention
The purpose of the invention is to overcome the above-mentioned shortcoming of the prior art, and provide a kind of weldment shape and ruler
Very little consistency is good, and welding quality is good, high production efficiency, automotive front crossbeam assembly welding procedure at low cost.
For achieving the above object, the specific process step that the present invention uses is: first compressing each component to be welded
Air blow drying is put into part frame to be welded, then carries out sequence welding: utilizing Special projection welding tooling by M6 nut projection welding to front beam
On upper plate；It will be in M6 square nut projection welding to front beam lower plate on projection welder using Special projection welding tooling；Utilize dedicated welder
Dress, manually spots weld casing in front beam stiffening plate；Using dedicated spot-welding equipment, before M6 square nut is spoted weld with robot
In crossbeam lower plate；Using specific welding assambly, front beam lower plate stiffening plate component is welded entirely with robot；Utilize special welding work
Dress, in robotic workstation, on Robot Spot Welding M6 nut to front beam upper plate；Using specific welding assambly, manually will
Stiffening plate stiffening plate spots weld above front beam upper plate；Using dedicated butt-joint tooling, design sequence butt-joint is pressed with dedicated butt-welding machine
Front cross beam welding assembly upper plate and lower plate；By the good front cross beam welding assembly of butt-joint, it is installed in robotic workstation, uses machine
People welds front beam assembly entirely；Tooth is returned in artificial scarfing cinder.
For the present invention due to using the above processing method, weldment shape and size consistency is good, and product qualification rate is high, production
High degree of automation, welding quality is good, and labor intensity of workers is low, and working environment is good, high production efficiency, at low cost, has and promotes
Application value.
Specific embodiment
Each component to be welded is dried up with compressed air first, is put into part frame to be welded, then carries out sequence welding: using specially
It will be on two M6 nut projection weldings to front beam upper plate with projection welding tool；Using Special projection welding tooling by M6 square nut on projection welder
In projection welding to front beam lower plate；Using dedicated spot-welding equipment, manually casing is spoted weld in front beam stiffening plate；Utilize dedicated point
Mounted welder is spoted weld 3 M6 square nuts in front beam lower plate with robot；Using specific welding assambly, welded entirely with robot
Front beam lower plate stiffening plate component；Using specific welding assambly, in robotic workstation, with two M6 nuts of Robot Spot Welding
Onto front beam upper plate；Using specific welding assambly, manually stiffening plate stiffening plate is spoted weld above front beam upper plate；Using special
With butt-joint tooling, design sequence butt-joint front cross beam welding assembly upper plate and lower plate are pressed with dedicated butt-welding machine；By the good preceding cross of butt-joint
Beam welding assembly, is installed in robotic workstation, welds front beam assembly entirely with robot；Tooth is returned in artificial scarfing cinder.
