Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a welding surface plate device of a new configuration used for butt welding plate materials.

``Prior art'' In general, butt welding of long plates is performed by first arranging the plates on a surface plate so that the grooves of each plate butt each other on the surface plate, and then welding each plate. Correcting lifting and misalignment of grooves between adjacent plates,
Next, the plates are temporarily joined together by spot welding the grooves of adjacent plates at appropriate intervals, and then the original welding is performed over the entire length of the grooves of both plates. This procedure is being implemented.

By the way, in the past, a method of using a type of wedge called a kinkagi has been used to correct the lifting of plates lined up on a surface plate, or to correct the misalignment of grooves between adjacent plates. It's here.

In this method, as shown in FIG. Enter 4 and
The plate material 2 of that part is pressed against the surface plate l. In the example shown here, the member 3 is protruded from an electromagnetic plate 5, and the electromagnetic plate 5 is fixed to the upper surface of the temporary +42 by electromagnetic force. It has become so.

[Problems to be Solved by the Invention] However, as mentioned above, the method of correcting the lifting of the temporary phase and the positional deviation of the grooves by punching the metal holes does not solve the problem of the degree of lifting of the plate material and the mutual position of the grooves. This method requires a worker to measure the degree of deviation, which poses a problem that it is not suitable for automation.

Furthermore, when driving the metal hole, the operator has to adjust the force for driving the metal hole depending on the degree of lifting and the degree of positional deviation between the grooves, resulting in poor workability.

However, if the plate material 2 to be welded is made of aluminum alloy or the like, magnets cannot be used.

This invention was proposed to solve the above-mentioned problem, and therefore, a plate placed on a surface plate can be restrained by operating a vacuum pump. It is possible to correct the lifting of plates and the misalignment of grooves between plates without using metal chips, making it suitable for automation and improving work efficiency when butt welding long plates together. It is an object of the present invention to provide a welding surface plate device that can be improved.

"Means for Solving the Problems" The welding surface plate device according to the present invention is a welding surface plate device that aligns the height positions of plate materials to be butt welded, and is It is characterized by sucking and restraining the plate from its underside with a vacuum pad connected to a vacuum pump.

"Function" In the above-described configuration, when the vacuum pump is activated, the suction force applied from the vacuum pad to the lower surface of the plate automatically draws the plate toward the substrate q side, and this suction force The movement of the plate is restrained, and lifting of the plate on the reference plane and misalignment of grooves between the plates are corrected.

Therefore, to correct the lifting of the plates placed on the surface plate or to correct the misalignment of the grooves between the plates, you can simply operate the vacuum pump, which is much easier than in the conventional case of using money. Therefore, there is no need for the operator to directly measure the degree of lifting of the plate material or the degree of positional deviation between the grooves, and the operator can adjust the force depending on the degree of lifting of the plate material or the degree of positional deviation between the grooves. This eliminates the need for manual work, making it suitable for automation and greatly improving workability when butt welding long plates together.

Embodiment FIG. 1 is a plan view of an embodiment of a welding surface plate apparatus according to the present invention.

This welding surface plate device is used to weld three long plates 2 against each other, and from three surface plate bodies 10 arranged at a predetermined interval, 142 and placed on top of each surface plate main body lO (align the height positions of the plates 142 to 142).

Each of the aforementioned plates 42 is butt-welded at its longitudinal side edges, and each side edge is beveled.
A groove portion K is formed.

As can be understood from FIGS. 2 and 3, each surface plate main body 10 has a rectangular frame and has a reference surface 1 on which the plate material 2 is placed.
an upper frame 12 formed along the circumference of the temporary first and second parts; legs 13 for setting the upper frame 12 at a predetermined height; and both sides of the upper frame 12 extending in the longitudinal direction of the plate material 2. The basic structure is a pad support member 14 bridging between the members 12a, 12a, and there is a space between the adjacent side members of the adjacent surface plate bodies 10 so as not to be affected by the heat during welding. , are spaced at a predetermined interval.

The pad support member 14 is provided at a plurality of locations at predetermined intervals in the longitudinal direction of the plate material 2 (in this embodiment, 1000
16 locations at mm pitch) and at positions lower than the reference plane 11.

Each pad support member I4 is provided with a vacuum pad 15 for sucking the plate material 2 from the lower surface side, and a suction positioning member 16 for regulating the position of the lower surface of the plate material 2 on both sides of the vacuum pad 15. The position of the upper surface 16a of the suction positioning member 16 is aligned with the reference surface 11.

As shown in FIG. 4, the vacuum pad 15 has a saucer-shaped receiver that is open at the top, and a pipe member 18 is connected to a pad 17 that comes into contact with the lower surface of the plate 2.
8 is connected to a vacuum pump (not shown), and uses vacuum pressure to adsorb the plate 2 placed on the reference surface 11 and restrain the plate 2, so that the center of the plate 2 is lifted up. The adsorption force is set so that it can be reliably adsorbed and restrained even in such cases. Further, the vacuum pad 15 is attached to the pad support member through a notch 14 formed in the pad support member 14 so that the tube member 18 is attached to the pad support member 14.
a, and then tighten nuts 19 screwed onto the pipe member 18 from both the upper and lower sides of the pad support member 14, and the height of the pad 17 can be easily adjusted by operating the nuts 19. It is made possible.

In the welding surface plate device configured as described above, when the vacuum pump is operated, the plate material 2 is automatically attracted to the reference surface 11 side by the suction force acting on the lower surface of the plate material 2 from the vacuum pad 15. The movement of the plate material 2 is restrained by this suction force, and the reference surface 1
Lifting of the plate material 2 on the plate material 1 and misalignment of the groove portions of the plate materials 2 with respect to each other are corrected.

Therefore, correction of the lifting of the plate material 2 placed on the surface plate and correction of misalignment of the grooves of the plate material 2 with respect to each other are as follows:
All you have to do is simply operate the vacuum pump, and compared to the conventional method that uses cash, there is no need for the operator to directly measure the degree of lifting or the degree of positional deviation between the grooves.
In addition, there is no need for the operator to adjust the force according to the degree of lifting of the plate material or the degree of positional deviation between the grooves, making it suitable for automation and making it possible to butt and weld long plates together. It is possible to greatly improve the work efficiency when doing so.

In the above embodiment, three plates 2 are welded together, but it goes without saying that the number of plates 2 to be welded can be set to any desired number by increasing or decreasing the number of surface plate bodies 10. .

Further, in the above-mentioned embodiment, a case was shown in which the plate materials 2 having the same thickness were welded to each other, but in the welding surface plate apparatus of the present invention,
Plywood for plate thickness adjustment is prepared for various plate thicknesses, and by using this plywood, even when plate materials of different thicknesses are welded together, it is possible to weld satisfactorily. Figure 5 shows the case of welding six types of plate materials 2a to 2f with different thicknesses, so the thickness of each plate material was set between each plate material 2a to 2f and each surface plate main body lO. By interposing the plywood 20a to 2Of, each plate material 2a
The height positions of the upper surfaces of ~2r are matched.

"Effects of the Invention" As is clear from the above description, the welding surface plate device of the present invention is a welding surface plate device that aligns the height positions of plate materials to be butt welded, and is a welding surface plate device that aligns the height positions of plate materials placed on a reference surface. It is characterized by suctioning and restraining the board from the bottom surface with a vacuum pad connected to a vacuum pump, and when the vacuum pump is activated, the suction force applied from the vacuum pad to the bottom surface of the board automatically The plate is attracted to the reference surface side, and this suction force restricts the movement of the plate and corrects lifting of the plate on the base surface and misalignment of the grooves between the plates.

Therefore, the floating plate placed on the surface plate is i.
) or the misalignment of the grooves between the handles can be corrected by simply operating a vacuum pump, and compared to the conventional case of using a metal cutter, the work noise can be directly affected by the level of lifting and the groove. There is no need to measure the degree of misalignment between the parts, and there is no need to adjust the force depending on the thickness of the plate material or the degree of misalignment between the groove parts. In addition, it is possible to greatly improve workability when butt welding long plate materials together.
