Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positioning and holding device for a transformer material or floor material, which holds the transformer material or floor material upright so that its upper end surface is at a predetermined height.

For example, a panel block for a ship's side can be manufactured by standing and welding double rows of transformer materials and longitudinal materials perpendicular to each other on a single skin material, or by welding two rows of transformer materials and longitudinal materials that are orthogonal to each other on one skin material. When manufacturing a double-structure panel block for the bottom of a ship by sandwiching and welding double rows of floor materials between skin materials, conventionally known assembly methods include the ``loose material distribution method'' and the ``frame material method.'' These include the "assembly method", the "line welder (longue attachment) and transformer material bulk insertion method", and the "(transformer material advance) longitudinal material bulk insertion method". However, in all of these conventional methods, aggregates such as transformer materials are held upright on the skin material and welded, so various devices such as holding devices and welding devices that operate from above interfere with each other. The disadvantage is that it is difficult to automate welding.

Therefore, when developing a new device that can automate welding, it is recommended to hold the double-row transformer material or floor material upright so that the upper end surface, that is, the mounting surface, is at a predetermined height. This is convenient because a predetermined shape can be obtained by simply placing a skin material on top of it.

The present invention was developed with attention to this point, and includes a pair of holding device bodies that can be moved toward and away from each other in the horizontal direction on a cart that can be moved vertically on rails, and a space between the two holding device bodies. A support bar that can be raised and lowered in a horizontal state and that can support the lower end of a vertically erected transformer material or floor material at a predetermined height, and a support bar that extends from each holding device main body to another holding device main body. a pair of vertical hydraulic cylinder devices that can be moved in and out and moved toward and away from each other; It has a pair of clamping jigs that clamp the material at a predetermined position from both sides. Therefore, the transformer material or the floor material can be held upright so that its upper end surface is at a predetermined height, and welding can be easily automated.

Hereinafter, one embodiment of the present invention will be described based on the drawings. 1 to 4, reference numeral 1 denotes a cart that is movable in the left-right direction (hereinafter referred to as "lateral direction") in FIG. Rails 2 are laid in the direction (hereinafter referred to as the "vertical direction"). 3 is rail 2
It is a cart that can be moved vertically on its upper surface, and a groove 4 whose bottom is wider than the opening is formed in the horizontal direction on its upper surface. 5 is a rack placed on the bottom of the groove.

On the truck 3, a pair of holding device main bodies 8 are provided, each having a convex portion 6 that is slidably fitted into the groove 4, and a pinion 7 that is built into the convex portion 6 and meshed with the rack 5.
is provided. A threaded rod 12 is provided on both sides of each main body 8 and is supported in the vertical direction by bearings 9 and 10 and is rotationally driven by a motor 11. Each threaded rod 12 has a nut 13 and 14, respectively. They are screwed together. Opposing nuts 13 and 14
A support bar 15, which is fixed to one nut 13 and slidably passes through the other nut 14, extends horizontally between them.

A notch 16 is provided in the upper part of the main body 8,
A slider 19 is provided in the notch 16 and is movable laterally within the notch 16 by being screwed onto a threaded rod 18 driven by a motor 17.
is located. 20 is a vertical hydraulic cylinder device configured to be able to move integrally with the slider 19; at the tip of the ram 21 that extends and contracts upward;
A pinching jig 23 having a square pinching surface 22 is provided, respectively.

In addition, 24 is a pair of automatic welding devices arranged on the side of the trolley 1 on the trolley 1, and a vertical rail 26 provided on a support 25 erected from the trolley 1, and this rail 26. a moving platform 28 movable on top and having lateral rails 27;
, a vertical hydraulic cylinder device 29 movable on a rail 27, and a welding torch 31 swingably pinned to the tip of an arm 30 that is raised and lowered by the hydraulic cylinder device 29. .

In the above configuration, when holding the transformer material 34 consisting of the frame portion 32 and the web portion 33 as shown in FIG. The pinions 7 and 17 are moved in accordance with the spacing between the members 34 and the pinions 7 and 17 are opened to open the space between the two holding device bodies 8 and the space between the two clamping jigs 23 according to the width of the fence portion 32, as shown in FIG. Next, the web section 32 is placed on the support bar 15, and the upper end surface of the web section 33 is adjusted to a predetermined height by driving the motor 11 to raise and lower the support bar 15. At the same time, the clamping jig 23 is adjusted to a predetermined height by the hydraulic cylinder device 20, and the motor 17
By driving the web portion 33, a predetermined position of the web portion 33 is pinched and held.

Transformer material 3 whose upper ends are aligned in this way
4 are arranged in double rows, a skin material is placed on top, and the two are welded by the automatic welding device 24, thereby assembling the above-mentioned ship side panel block.

Although not shown in FIGS. 1 to 4, when holding a floor material that does not have a facing section, the spacing between the main bodies 8 may be adjusted accordingly, and other functions will be controlled by the transformer material. Same as in case.

As described above, according to the present invention, the lower part of the transformer material or floor material is held by the holding device main body that can approach and move away from each other, and the upper part is held by the pinching jig, so that it does not protrude in the lateral direction such as the frame part. Even if a broken member is attached, this part can be held by the main body of the holding device, and the transformer material or floor material can be stably held in two places, upper and lower. In addition, the clamping jig can be moved vertically using a slide bar, so even if the transformer material or flooring material is high, the upper and lower parts can be held in two places, the clamping jig and the main body of the holding device, depending on the height. , its stability is not compromised. Furthermore, since the cart on which the holding device body is placed can be moved in the longitudinal direction along the length of the transformer material or floor material, even if members such as brackets are fixed to the transformer material or floor material, It is possible to select a location where the parts can be held stably by moving the cart while avoiding the members. In this way, it can accommodate transformer materials or floor materials as appropriate and can be held upright so that the upper end surface is at a predetermined height, making it easy to automate welding and automate the assembly of panel blocks. can be achieved.
