Abstract
The invention discloses a kind of large aircraft muscle siding T connector bilateral laser soldering methods, belong to technical field of laser welding.To solve the problem of that T connector and floor contact imprecision, itself verticality deficiency and generation fine displacements in T connector bilateral laser soldering method.Its device includes laser welding robot, auxiliary clamping robot, roller group A, roller group B, T connector, bottom plate, laser welding head.Before welding, T connector workpiece is placed in Working position, auxiliary clamping robot is clamped T connector, clamped position is divided into two parts, a part is that one group of idler wheel directly brings pressure to bear on T connector top, a part is the symmetric position that remaining two groups of idler wheels are clamped in T connector two sides, guarantees the verticality of T connector and reduces the fine displacements of workpiece.When welding, laser welding robot welds workpiece, and robot is completed to translate by mobile mechanism during the welding process.
Description
Technical field
The present invention relates to a kind of large aircraft muscle siding T connector bilateral laser soldering methods, are a kind of method for laser welding,
Belong to welding technology field.
Background technique
Aircraft manufacturing middle fuselage muscle siding generallys use T connector structure.And traditional manufacturing process mostly uses riveting work
Skill.It is manufactured compared to riveting, large-sized T shaped fuselage wallboard structure T connector bilateral laser synchronization welding can greatly mitigate work
Part weight improves production efficiency.In this high speed bilateral laser beam welding, rigging error between T-type stringer and covering,
Seam deformation in laser beam welding can all make the center of Laser Welding contact and weld seam deviate.It will lead to laser in this way
The quality of welding, which is deteriorated, even welds failure.Furthermore the attitude angle of T connector bilateral laser welding laser beam is to welding matter
Amount also has a major impact.
Summary of the invention
The present invention is to solve positional stability during aircraft manufacturing middle fuselage muscle wall T connector structure welding and ask
Topic, provides a kind of large aircraft muscle siding T connector bilateral laser welding apparatus.
A kind of large aircraft muscle siding T connector bilateral laser welding apparatus of the present invention, it includes one group (two) and swashs
Photocoagulation robot, one group of (two) auxiliary clamp robot, three groups of idler wheels.
Laser welding robot and auxiliary clamping robot are symmetrically assemblied in the welding workpiece i.e. two sides of T connector, and three groups
Idler wheel is loaded on disk by the front end that connector is assemblied in auxiliary clamping robot, and laser welding head is assemblied in laser-beam welding machine
The front end of device people is loaded on disk.
The large aircraft muscle siding T connector bilateral laser soldering method, it mainly includes process below:
T connector workpiece is placed in Working position first, secondly T connector is pressed from both sides by auxiliary clamping robot
Tightly, clamped position is divided into two parts, and a part is that one group of idler wheel directly brings pressure to bear on T connector top so that T connector in
Bottom plate can be preferably bonded, and a part is the symmetric position that remaining two groups of idler wheels are clamped in T connector two sides, guarantee that T-type connects
The verticality of head and the fine displacements for reducing workpiece.It is last then be that laser welding robot welds workpiece, and is welding
Robot is completed to translate by mobile mechanism during connecing.
The present invention can obtain it is following the utility model has the advantages that
Welder of the present invention, that is, large aircraft muscle siding T connector bilateral Laser Welding method, which realizes, is welding
The stability of T connector in the process, reduces the tiny offset of itself generation, and it is made to form good connect with bottom plate
Touching has the advantages that equipment is simple, facilitates and operate and easy to implement.
Detailed description of the invention
Fig. 1 is that the principle of large aircraft muscle siding T connector bilateral laser welding apparatus of the present invention and welding method is shown
It is intended to.
In figure: 1 being laser welding robot, 2 be auxiliary clamping machine device people, 3 be roller group A, 4 be roller group B, 5 be T-type
Connector, 6 be bottom plate, 7 be laser welding head.
Specific embodiment
The equipment that this example uses includes: 1, one group of auxiliary clamping robot 2, roller group of one group of laser welding robot
A3, roller group B4, T connector 5, bottom plate 6, laser welding head 7.Roller group A3 and roller group B4 is mounted on one group of auxiliary clamping
The front end of robot 2 is loaded on disk, and laser welding head 7 is installed on one group of 1 front end of laser welding robot and is loaded on disk.
T connector 5 is placed on bottom plate 6, is secondly clamped by auxiliary clamping robot 2 to T connector 5, clamping position
It sets and is divided into two parts, a part is that idler wheel A3 directly brings pressure to bear on 5 top of T connector, enables T connector 5 in bottom plate 6
Preferable fitting, a part is the symmetric position that roller group B4 is clamped in 5 two sides of T connector, guarantees the verticality of T connector 5
And reduce its fine displacements.It is last then be that laser welding robot 1 welds workpiece, and machine during the welding process
Device people is completed to translate by mobile mechanism.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, architectural form cans be flexible and changeable, can be with derivative series product.It only makes several
Simple deduction or replace are regarded as belonging to present invention scope of patent protection determined by the appended claims.
