A requisite part in welding equipment, is one of most important parts in laser welding apparatus, but is carrying out laser
During docking welding, focusing on tabula rasa needs accurate para-position, when plumb joint is perpendicular to surface of the work, the effect of welding with plate surface position
Preferably, laser beam glances off with plate surface to be likely to cause and welds unsuccessfully fruit, in actual test and production application,
Owing to inevitable existence artificially regulates the situations such as error, or the assembly precision error of sheet material, laser beam can be caused to hang down
Directly produce deflection to the left or to the right in surface of the work in vertical direction, it is possible to cause the appearance of weld on sheet material unstable.
Therefore, during actual welding, in order to ensure the shape stability of weld seam, it is necessary that laser beam and the upper table of workpiece
Face is vertical, forms good weldquality, and wherein, the upper surface of workpiece is workpiece welding plane.Owing to laser beam is from swashing
Send along axis in flush weld joint, therefore, adjust the perpendicularity of laser beam and workpiece surface, adjustment laser can be changed into
Plumb joint and the perpendicularity of workpiece surface, assert that workpiece surface is the most adjusted with horizontal plane concordant, then have only to adjust weldering
The perpendicular attitude of joint.The method of the perpendicular attitude of traditional regulation laser welding system is the most loaded down with trivial details, it is common that by steel ruler from
Both direction regulates the perpendicular attitude of plumb joint, by being directed at of Steel Ruler and horizontal plane, then left before and after regulation plumb joint
Right swing, concordant with the facade of Steel Ruler, this method must be on the basis of a horizontal plane, and this method measurement error is relatively
Greatly, for needing the workpiece of accurate welding, this method is the most inapplicable.
Disclose a kind of for Laser Welding in the Chinese invention patent file that notification number is CN104002051B authorized
The vertical detection device connect and detection method, this device is by arranging laser displacement sensor on plumb joint, and passes through displacement
The distance signal of sensor measurement is changed into the deviation angle signal of plumb joint by sensor controller, is then again adjusting
Whole, by the way of directly measuring deviation angle, measure perpendicularity, it is possible to relatively accurately measure the error of perpendicularity, but this device
Involved structure is more complicated and relatively costly, is not suitable for large-scale production.Therefore, relating to a kind of simple in construction, it is convenient to measure
Laser welding head unit and the verticality adjusting method of laser welding system necessary.

In horizontal level or be shown as described setting levelness.
Level indicator is bar formula air-bubble level, and the measurement datum of bar formula air-bubble level is that its bubble is horizontal
Time bar formula air-bubble level on the plane of plane-parallel, at least two side of plumb joint is provided with bar formula bubble level
Instrument, and the bubble moving direction of two adjacent or relative bar formula air-bubble levels is mutually perpendicular to, by bar formula air-bubble level
On bubble location determine incline direction and the angle of inclination of plumb joint, before and after regulation plumb joint, left and right is each successively
The angle in individual direction, until the bubble in each formula air-bubble level is all in horizontal level or is in the bubble position of setting
Put.
The invention has the beneficial effects as follows:
Compared to prior art, the laser welding head unit that the present invention relates to and laser welding system verticality adjusting method, create
Property use level measurement levelness principle, left-right and front-back swing plumb joint on level indicator, and level indicator are set
Reference measurement face vertical with the transmitting axis of the laser beam of plumb joint, measure whether this laser beam launches axis with this
Vertical with the welding plane of workpiece, the measurement of original plumb joint perpendicularity is converted to measure the level of level indicator on plumb joint
Degree measurement, then regulate plumb joint, until spirit level horizontal or be shown as set reading (the i.e. level of bar formula air-bubble level
Spend consistent with workpiece face of weld levelness), relatively simple for structure, and measurement effect is directly perceived, it is not necessary to complicated calculating and
Debugging, is arranged on the side of plumb joint only with level indicator, measures cost relatively low, and the debugging before welding has only to adjust workpiece
Horizontal plane, the debugging time is short, further promotes the efficiency of welding.
