Description

[Detailed Description of the Invention] The present invention provides a skin material (skin material) to which longitudinal material is attached.
This invention relates to a skin attachment device for welding transformer materials or floor materials.

For example, a panel block for a ship's side can be manufactured by standing and welding double rows of transformer material on one skin material with longitudinal materials attached, or by creating a double row transformer material between two skin materials with longitudinal materials attached. When manufacturing a double-structure ship bottom panel block by sandwiching and welding floor materials, conventionally known assembly methods include the "loose material distribution method", the "frame assembly method",
These include ``line welder (longue attachment) and transformer material bulk placement method'' and ``longue material bulk insertion method (with transformer material advance attachment)''. 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 advantageous to ensure that the transformer material or floor material and the skin material to which the longitudinal material is attached are bonded to each other.

The present invention has been made with attention to this point, and is a skin attachment device for a transformer material or a floor material and a skin material to which a longitudinal material has been attached, and includes a clip that holds the transformer material or floor material on a cart. A pair of holding device bodies having a fixture and movable close to each other are provided, and the lower end of the transformer material or floor material is connected to the holding device main bodies via a threaded shaft provided between the holding device bodies. A support bar that can be raised and lowered; a clamp device that can clamp a fixed longitudinal material to the lower surface of a skin material with longitudinal material mounted on the transformer material or floor material; The transformer includes a slide device for attracting the material to the transformer material or the floor material, and a hooking jig that can be hooked to the lower end of the transformer material or the floor material at the tip of an extendable slide bar connected to the slide device. The present invention is characterized in that it is provided with a cylinder device that pulls up timber or flooring material and attracts it to the skin material. This ensures that the welding is applied reliably, making it easier to automate welding.

Next, embodiments of the device of the present invention will be described based on the drawings. In FIGS. 1 and 2, a transformer material 1 is held by a holding device 2 in the vertical direction. That is, in the holding device 2, a cart 4 movable on the rails 3 is provided with a pair of holding device main bodies 5 that are movable on the cart 4 in the left-right direction in FIG. Reference numeral 6 denotes a pinching device attached to both holding device main bodies 5, respectively.
A vertical hydraulic cylinder device 7 is movable in the left-right direction in FIG. It is equipped with a pinching jig 8 that abuts from both sides.

Threaded rods 12 are provided on both sides of each main body 5, and are supported in the vertical direction by bearings 9 and 10 and rotationally driven by a motor 11.
Nuts 13 and 14 are screwed into the holes 2, respectively. A support bar 15 is horizontally extended between the opposing nuts 13 and 14 and is fixed to one nut 13 and slidably passes through the other nut 14. Therefore, the support bar 15 is connected to each threaded rod 12.
Since the support bar 15 has the support bar 15 placed on the support bar 15, the upper end surface of the transformer material 1 is raised and lowered to a predetermined height by driving the motor 11. This means that it can be positioned exactly.

Reference numeral 17 denotes a slide device fixed to the holding device main body 5 via a column 18, which includes a hydraulic cylinder device 19 in the vertical direction, a slide bar 20 extended upward by the hydraulic cylinder device 19, and a slide device 17 of the slide bar 20. Clamping device 21 provided at the upper end
It is composed of a differential transformer 22 for detecting the position of.

The clamping device 21 is attached to a skin material 23 placed on the upper end surface of the transformer material 1, and is attached to a notch 1a provided at the top of the transformer material 1.
It holds the longitudinal material 24 that is inserted into the holder. In this clamp device 21, 25 is a base column extending from the upper end of the slide bar 20,
A hydraulic cylinder device 27 that expands and contracts the slide bar 26 in the vertical direction is built therein.
Reference numeral 28 designates a pair of clamp bodies that are swingably pinned to the tips of the slide bar 26. A link 30 is connected between a predetermined position other than the center of swing of the clamp body 28 and a bracket 29 protruding from the side surface of the base column 25, and the clamp body 28 can be opened and closed by expanding and contracting the slide bar 26. I try to do that. Figures 1 and 2 show the clamp body 2.
8 is shown in its closed state, and FIG. 3 shows its open state. A cam 31 is attached to the tip of the clamp body 28.
are pinned so as to be swingable, so that even if the thickness of the longitudinal material 24 changes, it can be tightly attached to both sides of the longitudinal material 24 and held securely.

Another hydraulic cylinder device 32 is attached to the side of the hydraulic cylinder device 19 in parallel, and a slide bar 33 that extends downward in this hydraulic cylinder device 32 has a slide bar 33 that is hooked onto the lower surface of the frame portion 16 at the tip. A hooking jig 34 that can be stopped is provided. 3
5 is a differential transformer for detecting the position of the hooking jig 34.

Explain the action. The cart 4 is moved to correspond to the position of the longitudinal material 24, and the spaces between both the pinching devices 6 and between the two holding device bodies 5 are opened. Next, the support bar 15 is placed on the support bar 15, and the upper end surface of the transformer material 1 is adjusted to a predetermined height. After adjusting the clamping jig 8 to a predetermined height using the hydraulic cylinder device 7, both The hydraulic cylinder device 7 is brought close to clamp the transformer material 1 at a predetermined position. At this time, the clamp body 28 is assumed to be in an open state.

Thereafter, the skin material 23 to which the longitudinal material 24 has been attached is placed on the transformer material 1, and the clamp body 28 is closed to clamp the longitudinal material 24 as shown in FIG.
On the other hand, as shown in FIG. 2, the slide bar 33 is extended and the hook jig 34 is hooked to the lower surface of the fence portion 16.

In this state, if the hydraulic cylinder device 19 and the hydraulic cylinder device 32 are activated to draw the longitudinal material 24 toward the transformer material 1, the abutting portion 36 of the skin material 23 and the transformer material 1 will be brought into contact with the skin. Become. At this time, the hooking jig 34 and the clamp body 28
This attracts each other and maintains the stability of the device. Incidentally, since the positions of the clamping device 21 and the hooking jig 34 are detected by the differential transformers 22 and 35, the clamping operation and the hooking operation can be appropriately automated.

After that, when the contact portion 36 between the skin material 23 and the transformer material 1 is automatically welded, for example,
By simply moving a suitable automatic welding machine along this abutment portion 36, welding can be easily automated.

Note that when the longitudinal material 24 is welded to the skin material 23, the skin material 23 is distorted due to heat so as to swell toward the side opposite to the longitudinal material 24, so as described above, the longitudinal material 25 should be held and attracted. It is also possible to remove tobacco distortion.

As described above, according to the present invention, the longitudinal material is clamped and drawn to the lower transformer material or floor material by the clamping device and the slide device, and the distortion of the skin material to which the longitudinal material has been attached is removed and the longitudinal material is attached to the transformer material or floor material. The cylinder device can be used to hook the hanging jig to the lower end of the transformer material or floor material, and the slide device can be used to pull the clamped longitudinal material in the opposite direction. This holding device can be stabilized by lifting the transformer material or floor material using a cylinder device and attracting it to the skin material.Furthermore, since the skin material is placed on the upper end of the transformer material or floor material to hold it, it is possible to Compared to a device that holds aggregates such as transformer material upright on top of the skin material, there is no interference from the support part that supports the conventional holding device itself, making it easier to automate welding. This can be easily achieved and the assembly of panel blocks can be automated.
