TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column assembling / welding facility provided with a work rotating device in large-assembly welding of a long column having a connection.
[0002]
[Prior art]
Japanese Patent No. 2702444 (Patent Document 1) or Japanese Patent Application Laid-Open Publication No. 3-354443 (Patent Document 2) describes a mechanism for opening and closing a ring opening / closing unit for rotating a work and a disposition thereof.
Since the arrangement of the switching device is basically the same in both cases, the prior art will be described with reference to the above-mentioned Patent Document 1.
[0003]
FIG. 3 shows a simplified side view of a rotating device for rotating a long column (hereinafter referred to as a work). The rotating device 1 is housed in a temporary structure 2 and moves on a rail 3 to a predetermined position. In a state where the workpieces are fixed, two pairs of workpieces receive and hold and rotate. The welding device (not shown) moves in a direction parallel to the work on a rail arranged in parallel with the rail 3 of the rotating device, and welds the work at a predetermined position.
[0004]
Reference numeral 4 denotes a rotating ring mounted on the rotating device 1, reference numeral 5 denotes a part of the rotating ring 4, and an opening / closing portion which can be opened / closed when a work is attached / detached. Opened in the direction.
[0005]
The work 8 is suspended and carried by the crane from the upper left with the opening / closing section 5 opened to the upper right, lowered downward just above the rotating ring 4 and mounted in the rotating ring 4, and then moved up and down. It is fixed at a predetermined position in the rotating ring 4 by the right and left fixing jigs 9, 9 ', 10 and 10', and the mounting and fixing of the work is completed.
[0006]
Further, the work 8 is detached from the rotating ring 4 and transported outside by the reverse procedure.
The center height of the work with the connection, that is, the axial height of the rotating ring 4 is at least 2 m, and when the diameter of the rotating ring is 1.8 m, its upper edge becomes 2.9 m above ground, The height when the opening / closing part is opened at the top is almost 4 m. Therefore, the work 8 needs to be carried in from the upper left of the rotating ring 4 in a normal building factory where the hanging dimensions of the crane are limited.
A welding device (not shown) is also disposed on the right side of the rotating device 1 at a position where it does not hinder the loading of the workpiece.

[Problems to be solved by the invention]
In large assembly welding of long column materials, it is preferable that the welding device and the work be as close as possible for stable operation and stable welding (quality). For this purpose, it is necessary to minimize the horizontal space of the rotating device main body. is there.
Further, in the case of an articulated robot, the arm is extended instead of the guide rail to approach the work. For the same reason, the distance between the work and the welding device body should be minimized.
In addition, most of the companies involved in building processing and assembly equipment are small and medium-sized enterprises, except for a very small number of large fabricators. Reduction is an important issue.
[0009]
However, the state in which the opening / closing device 6 is disposed outside the rotating device 1 as in the above-described prior art is a situation that can be seen even in a factory that is actually operating, and in this state, the installation space is inevitably large.
[0010]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION In order to solve the above-described problems, the present invention provides a welding facility for assembling and welding a column held by a pair of work rotating devices. We propose a welding facility characterized by automatic opening and closing by the installed switchgear.
[0011]
In the present invention, since the opening / closing device main body and the link member are housed in the rotating device main body, the welding device main body can be arranged in a state closest to the rotating device, and the occupied area can be minimized.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a side view showing the configuration of the rotating device and the like of the present invention.
In the figure, reference numerals are the same as those described above, 1 is a rotating device, 4 is a rotating ring, 5 is an opening / closing section, 6 is an opening / closing device, and 7 is a link member.
[0013]
The jigs 9, 9 ′, 10, and 10 ′ for fixing the work are all of a manual type, and after the work 8 is fixed to the ring, the opening / closing section 5 is not shown at the joint with the rotating ring 4. It is manually fixed by a fixing jig.
[0014]
Automation of the opening operation of the opening / closing section 5 is effective in terms of safety and workability, but fixing with the fixing jigs 9 to 10 and fixing the opening / closing section 5 with the rotating ring 4 are performed at a high place. Since it is not a place, all are fixed manually to reduce costs.
[0015]
With the above-described configuration, the opening / closing unit 5 can be opened and closed without any trouble while the opening / closing device 6 and the link member 7 are all housed inside the rotating ring 4.
[0016]
FIG. 2 shows an arrangement relationship with a welding device in order to specifically explain the effect of the present invention, and is shown as a type equipped with a portable welding robot for convenience.
Reference numeral 11 denotes a welding device which moves in a state parallel to the rotating device 1, and a welding robot 12 is fed out to the upper portion of the work 8 by a guide rail 13 at a location corresponding to welding to perform welding.
[0017]
At this time, for stable operation and stable welding (quality), it is preferable that the welding device and the work are as close as possible to each other. To this end, it is necessary to minimize the horizontal space of the rotating device main body, but in the present invention, Since the opening / closing device 6 and the link member 7 are housed in the rotating device 1 main body, the welding device 11 main body can be arranged in the state closest to the rotating device 1, and the occupied area can be minimized.
[0018]
【The invention's effect】
As described above, according to the present invention, the welding device main body can be arranged in the state closest to the rotating device by keeping the opening / closing device main body and the link member in the rotating device main body, and the occupied area is minimized. be able to.
