【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an enlarged sectional view showing a box assembly backing metal mounting device of an embodiment of the present invention, FIG. 2 is a plan view showing the box assembly backing metal mounting device, and FIG. 3 is an explanatory view showing components of the box. 4 and 5 are sectional views showing the box. The box assembly backing metal attachment device A of this embodiment mainly includes a mounting table 1, a fixed side locking portion 2, a pressing means 3, and an advancing and retracting means 4. The mounting table 1 is for mounting the lower flange plate 50 for assembling the box 5 and both web plates 51, 51, and is formed to be long and is formed integrally with the machine frame 10. ing. In the figure, 11 is a long side on one side of the mounting table, and 12 is a long side on the other side. Further, 13 is an air pipe connected to the pipe on the factory side.

The fixed-side locking portion 2 is for accurately mounting the end surface 52 on one long side of the lower flange plate 50 and the web plate 51 at a predetermined position of the mounting table 1. In addition, a plurality of vertical surfaces 20 are aligned in a straight line and are vertically provided on one long side 11 of the mounting table 1 at predetermined intervals. In the figure, reference numeral 21 is a spacing member, which is detachably attached to the vertical surface 20 by a magnet or the like.

The pressing means 3 is for pressing and temporarily fixing the backing metal 53 arranged on the plate, and includes the column 30, the swing arm 31, and the air cylinder 32. It is formed by. The swivel arm 31 has a rear end rotatably supported by a tightening screw shaft 33 on the upper end of the support column, and is formed to be rotatable to an arbitrary position by loosening the tightening screw shaft 33. .. The support columns 30 supporting the swivel arm 31 are arranged at predetermined intervals on both long sides 11 and 12 of the mounting table 1, and the support section 30 disposed on one long side 11 is the above-mentioned. It is integrally fixed to the machine casing 10. The air cylinder 32 is fixed to the tip of the swivel arm 31 in a downward direction, and has a push seat 34 at the tip of the piston. Further, each of the air cylinders 32 is individually connected to the air pipe 13 via a controller 35.

The advancing / retreating means 4 is for adjusting the position of the pressing means 3 in correspondence with the plate widths of various sizes, and is one from the other long side 12 side of the mounting table 1. A guide groove 40 is opened toward the long side 11 side of the, and a screw shaft 41 is pivotally supported by the machine frame 10 at the same position as the guide groove 40 and below. Further, a female screw 42 is fixed to the lower end of the supporting portion 30 arranged on the other long side 12 side, and the female screw 42 slidably fits the supporting portion 30 into the guide groove 40. Is screwed onto the screw shaft 41. In the figure, numeral 43 is an adjusting handle.

Further, the pressing means 3 provided with the advancing and retracting means 4 is provided with a locking portion 45 having a vertical surface 44 that abuts the other side end surface 54 of the plate, similarly to the fixed side locking portion 2. It is fixed to each of the support portions 30.

Next, the operation of this embodiment will be described. First, the plate 50 forming the lower flange of the box 5 is mounted on the mounting table 1 with its one long side 52 being in contact with all the vertical surfaces 20 of the fixed-side locking portion 2. .. Further, all the columns 30 on the other side are advanced to the plate side by the handle 43, and the vertical surfaces 44 of the locking portions 45 are brought into contact with each other. Further, after attaching the spacing member 21 having the same thickness as the web plate 51 to the vertical surface 20 and the vertical surface 44, respectively, the backing metal 53 is attached in close contact with the side surface of the spacing member 21. Place it. Then, with all the swivel arms 31 oriented in the same direction, the air cylinder 32 is operated, the backing plate 34 presses against the upper surface of the metal 53 to temporarily fix it, and then from the starting end side of the plate. The backing plate 53 and the lower flange plate 50 are fixed by welding. After welding the area pressed by the pressing seat 34 with a predetermined pitch, loosen the screw shaft 33 for tightening and rotate the swivel arm 31 in the opposite direction to re-fix the backing plate so that the pitch is the same. Weld and fix in this way. After the backing plate is fixed by welding, the swivel arm 31 is swung toward the outside of the mounting table 1 and the completed lower flange plate 50 is taken out.

As described above, in the present embodiment, since the end surface position of the plate can be determined by the engaging portions 2 and 45 that are in contact with the long side end surfaces of the plate, the backing plate is Can be placed in parallel with the end face. Further, since the backing plate can be easily temporarily fixed by the air cylinder 32 of the pressing means, the operator is not burdened and the working time can be shortened. Further, since the pressing means 3 provided on the other long side 12 side of the mounting table 1 is formed so as to be movable back and forth, it can be used in correspondence with various plate widths.

Further, in the embodiment, since the air cylinder 32 of the pressing means 3 is attached to the swivel arm 31, it is possible to push the swivel arm left and right to press two places with one air cylinder. Therefore, the pressing pitch can be shortened, or the number of air cylinders attached can be reduced.

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to this embodiment, and the present invention can be made even if there is a design change within the scope not departing from the gist of the invention. Included in the device. For example, in the embodiment, the air cylinder is provided as the pressing means, but the present invention is not limited to this, and a hydraulic cylinder or an electric cylinder may be used, or a screw shaft or the like may be manually tightened to be temporarily fixed.

Further, in the embodiment, the backing plate is supposed to be performed by the air cylinder provided at the tip of the swivel arm, but the invention is not limited to this, and the swivel arm itself is lifted and pressed by the air cylinder. You may do it.

[Effect of the device]

 As described above, the backing metal attachment device for box assembly of the box column of the present invention has the above-mentioned configuration, so that the end face position of the plate on the mounting table can be determined. The backing plate can be arranged parallel to the end face without drawing a scribing line. Further, since the backing plate can be temporarily fixed by the pressing means, the welding work can be performed in a short time after the backing plate is placed on the plate, and the backing plate can be efficiently attached. The effect that can be obtained is obtained.
