Description
Technical field
The utility model relates to laser weld field, relates in particular to a kind of non-ferrous alloy laser weld paraxonic protective device.
Background technology
In laser beam welding, can produce dust, flue gas and other splashes.These dust etc. are easily attached on processing head eyeglass, thereby reduce the service life that light transmittance reduces eyeglass.Self all can have protective device current laser welding system, is mainly to utilize protection eyeglass or gas curtain to protect focusing lens.But do not consider the general protection of gas shield device to welding pool, or just in welding process among a small circle region carry out gas shield.
Non-ferrous alloy is the metal that activity is stronger, under high temperature, the gases such as oxygen, hydrogen, nitrogen is had to great affinity, and particularly in laser beam welding, oxidation is particularly violent.The stable variation of depending on plasma of laser beam welding, in welding, adopting inert gas to protect molten bath is the most general current employing method.Current laser welding system protective device only carries out simple protective, cannot meet technological requirement.Or considered blowing direction and blowing method can not effectively be controlled.Or the protective device just designing for specific weld seam.Or coaxial blowning installation is installed below main body, but protection zone is limited.Or have side blowing device in main body side, but the excessive interference that has is covered in holder, and applicable welding is limited in scope.
Present situation can be found out thus, and laser weld non-ferrous alloy requires in welding process and postwelding is better protected welding pool, but existing protective device is too simple.
Summary of the invention
The purpose of this utility model is to provide a kind of non-ferrous alloy laser weld paraxonic protective device, and by the side direction bindiny mechanism between support and laser head, the free adjustment of implement device moves, thus butt welded seam weld in and the gas shield of postwelding.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of non-ferrous alloy laser weld paraxonic protective device; comprise fixed support mechanism, four road protective gas nozzles, square platform shaped inflatable chamber; it is characterized in that; described fixed support mechanism is connected with top, square platform shaped inflatable chamber, and four road protective gas nozzles are connected with bottom, square platform shaped inflatable chamber.
Described square platform shaped inflatable chamber is provided with 4 protective gas air inlets.
Described fixed support mechanism by horizontal fixed block, slide up and down piece, swing piece forms.
The moving direction of described fixed support mechanism is provided with graduation mark.
Described fixed support mechanism displacement is between 100mm～200mm scope, and the anglec of rotation is between 0 °～90 ° scopes.
Described protective gas nozzle-axis and the angle of laser beam are between 15 °～30 ° scopes.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can be according to workpiece size and technological requirement, can independent assortment and the attitude of accurate adjustment air blowing pipeline, and protective device strong adaptability, welding protection region are large.The wing shape blowing method at four positions, is superior to ring-type blowing method, and protection zone is larger, in welding process, can not interfere workpiece.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Platform shaped inflatable chamber, protective gas nozzle 3-laser beam 4-side, the 1-fixed support 2-Si of mechanism road
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further illustrated:
As shown in Figure 1; a kind of non-ferrous alloy laser weld paraxonic protective device; by fixed support mechanism 1, four road protective gas nozzles 2, laser beam 3 and Fang Tai shaped inflatable chamber 4, formed; described fixed support mechanism 1 is connected with 4 tops, square platform shaped inflatable chamber; four road protective gas nozzles 2 are connected with 4 bottoms, square platform shaped inflatable chamber; platform shaped inflatable chamber, side 4 is provided with 4 protective gas air inlets, and all air inlets inner side is provided with screw thread.The square platform shaped inflatable chamber 4 Yu Si road protective gas nozzles 2 of being made by aluminium are connected.Side platform shaped inflatable chamber 4 height dimension 60mm, the width dimensions 20mm of bottom, 4 lower surfaces, square platform shaped inflatable chamber are provided with corresponding gas outlet, are directly connected with jet copper pipe, and a side is provided with lock-screw can regulate relative link position.Fixed support mechanism 1 by horizontal fixed block, slide up and down piece, swing piece forms, its moving direction is provided with graduation mark; Fixed support mechanism 1 displacement is between 100mm～200mm scope, and the anglec of rotation is between 0 °～90 ° scopes; The angle of protective gas nozzle 2 axis and laser beam is between 15 °～30 ° scopes.
Platform shaped inflatable chamber 4, side is connected with fixed support mechanism 2 by lock-screw, can rotate adjustment inflatable form.By 4 centre positions, square platform shaped inflatable chamber, connecting the jet copper pipe in Si road can protect in weldering and the molten bath of postwelding.The four tunnel first nozzles of protection valve 2 front end have gap and can strengthen protection zone; its excess-three protection gas jets becomes wing shape to distribute from same direction; and integral inclination is angled; when blowing, protect gas to be evenly distributed in four air jet pipes; wing shape pipeline plays and continues to supply gas effect; thereby protection welding position is not oxidated, especially protect position, molten bath in weldering.Thereby realize to molten bath protection and the inhibition of plasma, can meet the welding requirements of non-ferrous alloy laser welded parts.
