Description
[0001] The present invention relates to a two-axis positioner structure for arc welding, and more particularly, to a two-axis positioner structure for an arc welding, in which a pair of one-axis positioners rotated about a single rotation axis are provided, By providing a two-axis positioner structure that rotates about the horizontal axis and the vertical axis while maintaining a sufficient space between the axis-rotating base and the bottom surface, the balance weight can be basically installed, Axis positioner structure using single-axis positioners as well as a dual-axis positioner structure for arc welding which can improve the usability and compatibility of the two-axis positioner.
Generally, a welding robot refers to a device capable of automatically welding an object to be welded.
Such a welding robot itself is further provided with a positioner for automatically rotating the welding robot to perform a welding operation while rotating the welding object appropriately.
Such a positioner is usually a one-axis positioner that is rotated about any one of axes, that is, a horizontal axis that is normally horizontal in the left-right direction or a vertical axis that is vertical to the vertical direction. Is called a two-axis positioner.
For example, the conventional two-axis positioner includes a horizontal rotary shaft portion that is pivoted in a horizontal direction and axially rotated between a pair of vertically disposed shaft supports spaced apart from each other by a predetermined distance, And a vertical rotation axis portion that is rotated about a vertical axis.
The two-axis positioner can horizontally rotate the horizontal rotary shaft after mounting the welding object on the vertical rotary shaft, move the welding object on the vertical rotary shaft to a desired position, and the vertical rotary part rotates the object The position of the object to be welded with respect to the biaxial direction can be smoothly selected.
However, in the conventional two-axis positioner, since the horizontal rotation axis portion and the vertical rotation axis portion are integrally disposed on a single body, due to the structural problem that the horizontal rotation axis portion and the vertical rotation axis portion are inevitably disposed close to each other There is a problem that it is difficult to have a sufficient clearance space on the opposite side of the vertical rotary shaft portion and thus the installation of the balance weight on the opposite side of the vertical rotary shaft portion becomes difficult.
In addition, since it is a two-axis integral type structure, it is basically costly to manufacture, and the utilization aspect of the uniaxial positioner is not taken into consideration at all, so that the availability and compatibility of the equipment in the field are considerably deteriorated there was.
SUMMARY OF THE INVENTION The present invention has been conceived to solve such a problem, and it is an object of the present invention to provide a pair of single-axis positioners that are pivoted about a single pivot shaft, The balance weight can be installed basically by making the two-axis positioner structure rotate about the horizontal axis and the vertical axis while providing a sufficient space between the bottom surfaces. Thus, the safety of the balance weight can be improved, Axis positioner structure capable of realizing the functions of a two-axis positioner using positioners and improving the usability and compatibility of the two-axis positioner.
In order to accomplish the above object, according to the present invention, there is provided a two-axis positioner structure for arc welding, comprising: a first positioner having a first axis rotary arm that is axially rotated about a horizontal axis along a lateral direction; A first shaft rotatable arm of the first positioner is connected to one end of the first shaft rotatable arm and the other end of the first positioner is horizontally aligned with the bottom surface of the shaft rotatable base; A second positioner disposed on the upper surface of the shaft rotating base and having a second shaft rotating arm that is rotated about a vertical axis along a vertical direction; A slave shaft rotating arm connected to the other end of the shaft rotating base and rotated in an axial direction corresponding to the shaft rotating of the shaft rotating base; And an axis rotation support base for supporting the axis rotation of the driven shaft rotation arm.
Further, in the two-axis positioner structure for arc welding according to an embodiment of the present invention, the shaft rotation base is disposed at a predetermined height above the bottom surface so as to have a sufficient distance between the bottom surface and the bottom surface of the shaft rotation base, And a pedestal may be further provided on the bottom surface of the first positioner so that the first positioner corresponding to the first positioner is located above the predetermined height.
In addition, in the two-axis positioner structure for arc welding according to an embodiment of the present invention, a balance weight may be further provided so as to maintain a balance of the offset load of the object to be welded provided above the second positioner.
Further, in the two-axis positioner structure for arc welding according to an embodiment of the present invention, a plurality of balance weights may be disposed on the bottom surface side of the shaft rotating base.
Also, in the two-axis positioner structure for arc welding according to an embodiment of the present invention, the plurality of balance weights may be disposed on the bottom surface of the shaft rotating base corresponding to both sides thereof with respect to the second positioner have.
As described above, the two-axis positioner structure for arc welding according to the present invention includes a pair of single-axis positioners that are pivoted about a single pivot axis, and are spaced sufficiently apart from each other with a pivot base interposed therebetween, The balance weight can be installed basically by providing a two-axis positioner structure that rotates with respect to each of the horizontal axis and the vertical axis while providing a sufficient space between the rotating base and the bottom surface. Of course, the functions of the two-axis positioner can be implemented by using single-axis positioners, thereby improving the usability and compatibility of the apparatus.
