Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
Embodiment one：
The welding tractor of rail-free generally requires the good weldering that could be realized using weld seam tracking sensor guiding to weld seam
Connect.It is this utility model on the basis of welding tractor concept, less freedom can be added with the moving cell of adjustment direction by providing
Mechanical arm is spent, and the arc welding robot scheme of creeping that the sensor for coordinating weld seam tracking sensor to use guides.
As Figure 1-3,1 is walking dolly to its structure, and 2 be mechanical arm, wherein 201 be lifting joint, 202 be realization
The telescopic joint of horizontal adjustment, 203 detect the revolute joint in direction for adjustment weld seam tracking sensor, when running into weld seam turning position
It when putting, can be pre-adjusted before walking dolly 1 is not yet turned, weld seam tracking sensor 4 is always positioned at monitoring weldering
The position of seam and be unlikely to lose target.As shown in figure 1,3 be welding gun, 4 be weld seam tracking sensor.Wheel in walking dolly
Son can use the mechanisms such as differential or directive wheel to realize that the overall of robot turns to.
The arc welding robot use of creeping of the sensor guiding of the present embodiment can detect the weld seam of weld penetration information with
Track sensor, before the welding gun at a certain distance from, the position of weld seam can be perceived in advance before welding gun arrival.According to inspection
The actual welds position measured, adjust the horizontal level of welding gun and the height of welding gun.
In welding process, because weld seam tracking sensor always observes one section i.e. by the weld seam of welding in advance, according to
Robotics principle, the locus of the weld seam can be calculated, as long as walking dolly occurs without skid with road surface
Phenomenon, you can by adjusting walking dolly and mechanical arm, realize that welding gun does not depart from the physical location of weld seam.
When welding gun reaches turning, if radius of turn is smaller, it is difficult to controlled by wheel speed and keep speed of welding, may
The speed of welding gun have to be lower than preferable speed of welding, in order to ensure the welding wire melted at welding point is not accumulated excessively, still
It can be achieved the goal by reducing the measure of welding arc thermal output.At this moment need to be known a priori by the sectional area of weld seam, or
Person's sensor is capable of detecting when the sectional area of weld seam, is used for control deposition rate.
The weld seam tracking sensor of the arc welding robot of creeping of the sensor guiding of the present embodiment is illustrated in figure 6, it is sent out
Go out the generating laser 5 of beam of laser, laser beam fan is projected and the surface shape of workpiece 6 where weld seam by sweep mechanism
Into series of points shaped laser spot, it is arranged on the transversal of a weld seam, the transversal is approximately perpendicular to weld seam.The laser beam of scanning
Coordinate with the first image acquiring sensor 7, form laser vision, detect the surface topography of weld seam, and then detect weld seam
Height and position and horizontal position information.Second image acquiring sensor 8 then independently shoots the 2D gray level images of weld seam, to the figure
As analyzing and processing, it is only capable of obtaining the horizontal position information of weld seam, and the height position information of weld seam can not be obtained.Melted by information
Conjunction technology, the weld seam horizontal position information synthesis that two different approaches obtain is turned into more accurate, more reliable weld seam horizontal position
Confidence is ceased, and foundation is provided for the TRAJECTORY CONTROL of welding gun.
Furthermore, it is possible to increase reflective mirror in the way that laser beam advances, realize and fold light path, reduce overall dimensions.Especially
Ground, use can make the reflective mirror of minute angle vibration, and the deflection angle of laser beam is also to be supervised when gathering image information
Control, so that it may so that laser beam can scan between each hot spot, reach all standing of the hot spot to detection section.Employ one side
The reflective mirror of minute angle vibration is made, between the side-to-side vibrations limit, corresponding hot spot can be with the complete of inswept two neighboring hot spot
Portion's line segment, as long as that is, hot spot scanning displacement be more than two neighboring hot spot between ultimate range.Thus may be used
Fine test point hot spot can be equally obtained to reduce the quantity of generating laser.
Embodiment two：
During due to not using guide rail, the path accuracy that walking dolly is realized in some cases may decrease, and may be used also
To increase a sensor at the rear portion of welding gun, as shown in figure 4, more information are improved for welding gun TRAJECTORY CONTROL, to improve
TRAJECTORY CONTROL precision.
If walking dolly can be in welding process with opposite direction in above-mentioned various situations, equivalent to by machinery
Arm is changed as right arm type working method, conveniently adapts to usage scenario.In the case of using single weld seam tracking sensor, only
Sensor need to be turned 360 ° by revolute joint 203.
Embodiment three：
In addition, welding gun and weld seam tracking sensor can also change an angle around trunnion axis, to complete angle welding
Task, as shown in Figure 5.
It the above is only preferred embodiment of the present utility model, be not limited to the utility model, it is noted that for
For those skilled in the art, on the premise of the utility model technical principle is not departed from, if can also make
Dry improvement and modification, these improvement and modification also should be regarded as the scope of protection of the utility model.
