Background technology
Welding is the process of a kind of necessity in modern mechanical manufacturing industry, is used widely in automobile making.Along with the progress of science and technology, the Welding Problems of clad steel sheet, light metal material proposes new challenge to Automobile Welding.Robot in Automobile Welding process and automatic laser solder technology make Automobile Welding looks greatly take on a new look.The develop rapidly of auto industry, makes laser welding technology open the New Times of Automobile Welding.
Different from spot-welding technology traditional at present, the molecule that laser weld can reach between two block plates combines, and the steel plate hardness after popular welding is exactly equivalent to a monoblock steel plate, thus bus body strength is promoted 30%, equally greatly promoting in conjunction with precision of vehicle body.Certainly, the actual use meaning of laser weld is also not only in this.In general, from the torsional motion test vehicle body that can convert thousands of times per minute to that jolts on ground when vehicle is advanced on road, if vehicle body is in conjunction with precision, insufficient strength, light then in car frequent, the noise of abnormal sound large, serious may cause being arranged on parts on vehicle as the damage of gearbox, front-rear axle or vehicle body fracture.The spot welding that laser weld is relatively traditional as can be seen here has greater significance.
At present, in order to better improve automobile metal plate work welding efficiency normally laser welding robot sheet metal component is welded.It is large that laser welding robot has the radius of gyration, the feature that the welding free degree is large, is widely used.Laser welding robot is mainly made up of base, main rotary electric machine, main rotary shaft, secondary rotary electric machine and secondary turning cylinder etc. usually, base is connected by main rotary electric machine with main rotary shaft, main rotary shaft is connected by secondary rotary electric machine with secondary turning cylinder, the free end of secondary turning cylinder is provided with laser welding system, and laser welding system is connected by micro servo motor with secondary turning cylinder.Because the laser welding system on existing laser welding robot is all rotate synthesis by a series of revolution, but some panel beatings to be carried out to small straight line welding very difficult, need robot to do a series of resultant motion, consume energy very much.
Now need as can be seen here to design a kind of laser welding robot for small straight line seam welding.
Summary of the invention
The object of the present invention is to provide a kind of laser welding robot less for small straight line seam welding power consumption.
For achieving the above object, base case of the present invention is: a kind of laser welding robot, comprise laser welding system and be positioned at the control panel on secondary turning cylinder, described laser welding system comprises laser nozzle and circular swing tube, described laser nozzle is positioned at circular swing tube, described circular swing tube inwall same is circumferentially provided with four uniform electromagnet, electromagnet is electrically connected with control panel, four electromagnet form annular chamber, the afterbody of laser nozzle is provided with annular magnet, and annular magnet is positioned at annular chamber.
Operation principle and the advantage of this programme are: during for small straight line seam welding, and first start the machine people, and laser welding system is positioned at above weld seam.Then regulated the electrical current of coil on four electromagnet by control panel, and then reach the magnetic force of adjustment four electromagnet.When the magnetic force that annular magnet is subject to is uneven, annular magnet can move thereupon, and then reaches the object of laser nozzle movement.
The ingenious annular magnet that utilizes of this programme is in the magnetic field of four electromagnet formation, and when the field is changing, laser nozzle moves with annular magnet.During for small straight line seam welding, the magnetic force size of corresponding just right electromagnet only need be regulated can to realize laser nozzle rectilinear movement, not need robot to do complicated gyration synthesis, and then reach the object reducing energy consumption.In addition, the mobile accuracy due to laser nozzle mainly samples in the Current Control of control panel to electromagnet, and reduce the impact of corresponding part's machining errors on laser nozzle mobile accuracy, it is high that break-in improves welding precision.
Preferred version one: based on the preferred version of scheme, described electromagnet is provided with anti-collision air bag, and anti-collision air bag avoids operating personnel's maloperation to cause laser nozzle to strike on circular swing tube, affects the service life of laser nozzle.
Preferred version two: the preferably preferred version of: described electromagnet is provided with some coilings electricity circle, this coiling electricity circle is electrically connected with control panel.Can magnetic field be formed after the energising of coiling electricity circle, by coiling electricity circle, small correction be carried out to the movement of annular magnet, and then improve the precision of laser nozzle movement.
Preferred version three: the preferably preferred version of two: afterbody and the annular magnet of described laser nozzle are fixed by expansion sleeve.Expansion sleeve is convenient to the fixing of laser nozzle and annular magnet, when laser nozzle need repairing change time, facilitate laser nozzle to dismantle from annular magnet.
Preferred version four: the preferably preferred version of three: described expansion sleeve is rubber swelling cover, described electromagnet is lower arcs of recesses near the end of laser nozzle, and described coiling electricity circle is matrix distribution at electromagnet near the end of laser nozzle.When four electromagnet are energized simultaneously, a toroidal magnetic field can be formed, more have the motion utilizing adjustment ring shape magnet.Coiling electricity circle, in matrix distribution, reduces the turbulent flow in magnetic field, advantageously does rectilinear motion in annular magnet.
