Description
Technical field
The present invention relates to field of welding devices, especially a kind of laser filler welding machine and welding method thereof.
Background technology
The kind variation of existing welding, is divided into melting welding, pressure welding and soldering according to its process characteristic, and wherein melting welding comprises arc welding, gas welding, Laser Welding, plasma weldering etc.Wherein arc welding is simple to operate; equipment is simple; it is that the welding rod that scribbles coating with outside is made electrode and filled metal; electric arc is to burn between the end of welding rod and welded piece surface; coating can produce on the one hand gas with protection electric arc under arc heat effect; can produce on the other hand slag and cover weld pool surface; prevent the interaction of deposite metal and ambient gas; but arc welding can be welded the larger object in gap; the crator producing is obvious; and out-of-flatness, the quality of welding is relatively low.And the welding that Laser Welding is the laser beam that utilizes high-power relevant monochromatic light subflow to focus on to form carries out for thermal source, Laser Welding advantage is not need to carry out in a vacuum, it is strong that shortcoming is that penetration power is not so good as electron beam welding.When Laser Welding, can carry out accurate energy control, thereby can realize the welding of accurate miniature device, it can be applied to a lot of metals, particularly can solve the welding of some welding-resistant metals and dissimilar metal.But the gap of the object that Laser Welding can be welded is less, cause the object range of its welding relatively little, affect its scope of application.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and a kind of laser filler welding machine and welding method thereof of carrying out filler in the process of laser weld is provided, increased the scope of its welding weld seam.
In order to achieve the above object, the laser filler welding machine that the present invention is designed, it comprises laser welder, manipulator and controller, described manipulator is arranged on pedestal, described laser welder is fixed on the top of manipulator, be provided with welding wire conveyer at the side of manipulator, welding wire conveyer is provided with delivery hose, delivery hose is connected to the below of laser welder, on laser welder, be provided with connecting rod, the top of connecting rod and delivery hose is connected and fixed, the straight line at the welding wire place of stretching out on the top of described delivery hose and the straight line at the laser beam place of laser welder are crossing, and the top of welding wire be positioned at laser welder laser beam transmitter under, described controller respectively with laser welder, manipulator and the electrical connection of welding wire conveyer.
Technique scheme, laser welder is arranged on manipulator, and control manipulator and laser welder by controller simultaneously, realize the automatic welding of laser welder, and the setting of welding wire conveyer, the below by welding wire synchronous transport to the laser beam transmitter of laser welder, utilize laser beam by wire melting, enter and in the weld seam between soldered object, carry out filler, thus can effectively raise can laser weld weld width, maximum weld width can reach 1mm; And by controller Synchronization Control manipulator, welding wire conveyer and laser welder, three's action is coordinated, avoid welding wire carry too fast or cause excessively slowly weld seam uneven whole, thereby can improve welding quality.
As optimization, be arranged with one or more welding product frock clamps at pedestal outer; Be preferably: the quantity of described welding product frock clamp is two, and centered by pedestal, a symmetrical side that is arranged on pedestal.After the frock clamp of a side completes product clamping, laser welder welds it, and the while is carried out the clamping to product on the frock clamp of opposite side, after the former welding completes, can weld the latter, and the former can unload product and from new installation product to be welded at once, can improve greatly the utilization rate of laser welder, the vacancy rate of reduction equipment, reduces the production cost of enterprise, enhances productivity.
A kind of welding method of laser filler welding machine, first controller control manipulator moves to one end of the weld seam between soldered object, start laser welder, manipulator drives laser welder along weld movement, welding wire conveyer is outwards carried welding wire simultaneously, and the multiple relation of displacement after can regulating welding wire output length and laser welder to start by controller according to the size of weld seam, after whole piece weld seam has welded, laser welder cuts out, welding wire conveyer stops action simultaneously, and laser welder is moved to assigned address by manipulator; Repeat above-mentioned action, to welding between soldered object.
Laser filler welding machine and welding method thereof that the present invention obtains, it is by the setting of welding wire conveyer, and the top of delivery hose is connected to the below of laser welder, and the welding wire of output is crossing with laser beam, utilizes laser beam by wire melting, and enters in the weld seam of weld, thereby can effectively increase the value range of weld seam that can laser weld, the width of the weld seam of maximum weld can reach 1mm, has improved the scope of application of laser weld, and makes laser weld effect more excellent.
