Abstract
Torsion beam welding procedure after a kind of CS9, it is characterized in that carry out sequence welding after first being cleaned each relay part to be welded.Product can guarantee the consistency of torsion beam assembly weld size and each portion's shape, easy to operate, safety, high production efficiency, at low cost, have application value.
Description
Technical field
The present invention relates to a kind of metal parts welding procedure, torsion beam welding procedure after especially a kind of CS9.
Background technique
Torsion beam is an important component on automobile rear chassis, and the two sides of torsion beam are mounted with wheel hub and brake disc etc. zero
Part is mounted with damping device and swing arm on its four angles of front-rear direction respectively, is connected by damping device and swing arm with vehicle body
It connects, when vehicle traveling is in flat road surface, torsion beam quadrangle stress balance, automobile balance traveling, torsion beam middle section is substantially
Do not play twisting action；When running car is at uneven road surface, automobile back wheel is one high and one low, and twisting states are presented in body of a motor car,
The torsional moment of vehicle body is transmitted in torsion beam at this time, and the torsion of vehicle body is eliminated by the rigid torsion of torsion beam, makes automobile still
The state of energy board balance traveling.
The welding procedure of current torsion beam is that all punching parts are all uniformly installed on welding tooling, after spot welding,
Unify full weldering again, due to the difference of welding sequence and welding parameter, causes the torsion dye assembly of welding in shape and size, installation
Size is inconsistent, influences the assembly of rear process, and inconvenient for operation, and production efficiency is 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 it is consistent to provide a kind of shape, size
Good, easy to operate, the torsion beam welding procedure after high production efficiency, CS9 at low cost of property.
For achieving the above object, the concrete technology method that the present invention uses is first to clean each relay part to be welded
Carry out sequence welding afterwards: the part that equal group is welded, such as conduit, trailing arm outside plate, trailing arm inner plate, side rail are installed to special welding
On fixture, with each group welding piece of Robot Spot Welding, each group welding piece is then welded entirely again；By crossbeam, brake pipe bracket is reinforced under crossbeam
Part, torsion bar assembly are installed on welding fixture special, with each group welding piece of Robot Spot Welding, then weld each group welding piece entirely again；It will weldering
Connect trailing arm component, crossbeam assembly, shock absorber support assembly, spring mounting seat, buffer limit seat, reinforcer on crossbeam stays dynamic draw
Lock support, flange connections assembly are installed on welding fixture special, and with each weld assembly of Robot Spot Welding, then full weldering is each again
Component；Torsion beam assembly will have been welded and carried out artificial full inspection, the position not being soldered to carries out artificial repair welding, manually removes welding slag, welds
At seam exhaustive test and label is performed with marking pen；By the good torsion beam assembly of repair welding, it is special that processing is installed to crane hanging
The processing of flange both ends of the surface is carried out on machine, guarantees the angle of mounting surface and the size of each fitting machine；Manually each processing is removed with file
The burr at position.
For the present invention due to using process above method, product can guarantee the one of torsion beam assembly weld size and each portion's shape
Cause property, easy to operate, safety is high production efficiency, at low cost, has application value.
Specific embodiment
Torsion beam welding procedure after a kind of CS9, carry out sequence welding after first being cleaned each relay part to be welded: by etc. groups
The part of weldering, such as conduit, trailing arm outside plate, trailing arm inner plate, side rail is installed on welding fixture special, each with Robot Spot Welding
Then group welding piece welds each group welding piece entirely again；By crossbeam, brake pipe bracket, reinforcer under crossbeam, torsion bar assembly is installed to dedicated
On welding fixture, with each group welding piece of Robot Spot Welding, each group welding piece is then welded entirely again；Trailing arm component will be welded, crossbeam assembly subtracts
Shake device bracket assembly, spring mounting seat, buffer limit seat, reinforcer on crossbeam stays dynamic zipper bracket, flange connections assembly peace
It is attached on welding fixture special, with each weld assembly of Robot Spot Welding, then welds each component entirely again；Torsion beam assembly will have been welded
Artificial full inspection is carried out, the position not being soldered to carries out artificial repair welding, manually removes welding slag, and commissure exhaustive test simultaneously uses marking pen
Perform label；By the good torsion beam assembly of repair welding, it is installed on special machine tool with crane hanging and carries out flange both ends of the surface processing,
Guarantee the angle of mounting surface and the size of each fitting machine；The burr of each working position is manually removed with file.
