Detailed description of the invention
The following is embodiments of the invention, it is only with and unrestricted with explanation of the present invention.
Figure 1 shows that the side view of a kind of string bead side force tracking means of the present invention, it comprises servo follow-up tracing mechanism 1, Eight characters tracking wheel electric lifting mechanism 2, electronic deviation correction mechanism 3, welding gun governor motion 4 and the parts such as laser pen 20 and camera 19;
Wherein, base 9 is fixedly connected on welding equipment 23, and upper link 10 is slidably connected with base 9 by the first line slideway auxiliary 5, centering cylinder 8 is installed on base 9, locating dowel 6 is fixedly connected on base 9, and locking cylinder 7 is fixed on base, and they form servo follow-up tracing mechanism 1 jointly.
Edge-on seat 11 is fixedly connected on the upper link 10 of servo follow-up tracing mechanism 1, reducing motor and roller bearing screw component 12 are connected on edge-on seat 11 by the first line slideway auxiliary 13, Eight characters tracking wheel 15 is connected with roller bearing screw component 12 with reducing motor with pressure sensor 14 by tracking wheel clamping device 16, and they form Eight characters tracking wheel electric lifting mechanism 2 jointly.
Electronic deviation correction mechanism 3 is made up of the traversing assembly 17 of reducing motor and transition connecting plate 18.The traversing assembly of reducing motor 17 is arranged on edge-on seat 11, and transition connecting plate 18 is arranged on the second line slideway auxiliary of the traversing assembly 17 of reducing motor.
Welding gun governor motion 4 is arranged in transition connecting plate 18, and welding gun 22 is connected on welding gun governor motion 4 by welding torch clamping mechanism 21, and laser pen 20 and camera 19 are also arranged on welding gun governor motion 4.
The upper junction plate 10 of described servo follow-up tracing mechanism 1 can drive welding gun 22 to carry out left and right and be free to slide.Centering cylinder 8, under the restriction effect of locating dowel 6, can realize during upper junction plate 10 automatically returns, in that is to say that welding gun 22 returns automatically.Described locking cylinder 7 can realize the locking of upper junction plate 10.
The Eight characters tracking wheel 15 of described Eight characters tracking wheel electric lifting mechanism 2 can electronic rising and decline under the effect of reducing motor and roller bearing screw component 12, thus can according to actual welding situation, welding gun 22 to proper height is regulated before welding starts, and in welding process, keep this height, and ensure that welding effect is reliable.The pressure of described Eight characters tracking wheel 15 pairs of steel pipes 24 can be detected by pressure sensor 14.
Before welding starts, center line and the welding gun 22 of laser pen 20, camera 19, Eight characters tracking wheel 15 should be adjusted on straight line.Welding gun 22 can under the effect of electronic deviation correction mechanism 3, and the accurate adjustment of free left and right is carried out in the impact not by servo follow-up tracing mechanism 1, ensures that welding gun 22 welds in the welding position of the best.
Figure 2 shows that the end view drawing of a kind of string bead side force tracking means of the present invention in steel duct, as can be seen from the figure this device is at the actual working state of steel pipe 24 inside.Figure 3 shows that the stressed schematic diagram of Eight characters tracking wheel of the present invention in steel duct.
Before welding starts, welding equipment 23 is applied to the power that Eight characters tracking wheel 15 size is all F1 and F11 mutually, and the corresponding active force of steel pipe 24 pairs of Eight characters tracking wheels 15 is F2 and F22.Pressure F1 and F11 that they are applied to Eight characters tracking wheel 15 at the component F4 of vertical direction and F44 component and welding equipment 23 is in the same size, cancels out each other; And component F3 and F33 of F2 and F22 in level is just contrary on direction, when there is deviation in the axial direction in steel pipe 24, if when its component F3 being applied to tracking wheel 15 is greater than component F33, under the effect of side force, servo follow-up tracing mechanism 1 will move with welding gun 22, until F3 and F33 is in the same size.Otherwise identical, servo follow-up tracing mechanism 1 oppositely will move with welding gun 22, until F3 and F33 is in the same size.Thus realize welding gun 22 and move along the axis direction of steel pipe 24 all the time, also namely realize welding gun 22 and carry out from motion tracking along bead direction.
When difference between side force F3 and F33 is less, when that is to say that steel pipe 24 misalignment of axe is little, at this moment when side force is not enough to affecting of the frictional force overcoming servo follow-up tracing mechanism 1, because now deviation is very little, the relative position of laser spots and weld seam can be observed in monitor, utilize electronic deviation correction mechanism 3 to carry out trickle accurate adjustment whole, ensure that welding gun 22 welds along correct position all the time, thus ensure welding quality;
Adopt the side force tracking of a kind of string bead side force tracking means of the present invention that the actual welds groove track of the movement of welding gun 22 and seam track and workpiece can be made to be consistent, avoid being partially welded and cause weld defect.Supporting with welding equipment 23, be applicable to the interior pass weld of vertical masonry joint metallurgical composite pipe internal coated layer and slab straight-line joint submerged arc welding tube.
In said apparatus, if without the need to manually rectifying a deviation, then can remove electronic deviation correction mechanism, namely removing the traversing assembly 17 of reducing motor, laser pen 20 and camera 19, only rely on the realization of Eight characters tracking wheel for the correction of welding position.
It is emphasized that: be only preferred embodiment of the present invention above; not do any pro forma restriction to the present invention, every any simple deformation of doing example and method thereof according to technical spirit of the present invention or amendment are all within the protection domain of this patent.
