The present invention relates to an automatic reinforcing panel mounting device of the shipboard panel that allows to align and weld the two reinforcement to a single device at the same time for automatic mounting welding of the reinforcement to the bow and stern panel of the ship.

In general, the ship's structure is divided into three parts, bow part, hull middle part and stern part, and since the hull middle part produces standardized panels, it is easy to mass-produce and automate with a simple work process, but the bow and stern part are composed of irregular shapes. Since the reinforcement on the abacus must be accurately attached to the mounting line and maintained at right angles during the welding process, the spacing between the reinforcement and the abacus must be within the allowable range. to be.

Conventionally, the process of mounting and welding the reinforcement on the panel of the bow and the stern is dependent on manual work or using some tools to produce the panel.

The above manual work is to make a separate jig and put a wedge with a hammer between the jig and the reinforcing material so that the reinforcing material is in close contact with the main plate, and it is mounted by manual welding. Was used.

The conventional method as described above has a problem in that a large amount of labor is input to the reinforcement to close the abacus using a tool, a jig, a vacuum pad, a hydraulic device, and the like, and a gap between the reinforcement and the abacus is uniformly allowed. It was difficult to maintain and wider than the allowable gap, there was a problem such as a welding defect occurs.

Therefore, the present invention was created for the purpose of solving the above-mentioned problems, and in the production of irregularly shaped panels such as bow and stern, it is possible to align and weld two reinforcements to the main plate at the same time with a single device. Improve the productivity of the bow and stern panel by installing the reinforcement on the abacus accurately and attaching the reinforcement to the mounting line and managing the gap between the abacus and the reinforcement within the allowable range while maintaining the perpendicularity of the abacus and the reinforcement. It is to provide an automatic welding device that can be easily operated.

In order to provide the above automatic welding device, both the columns of the girders are driven up and down by means of shafts, and two sets of auxiliary cranes are mounted on the side of the girders, and girder saddles are used to align the mounting lines of the main plate and the reinforcement. The overcarriage saddle is installed separately and consists of eight welding bogies in one welding beam and four welding torches in each welding bogie.

The welding beam is adjusted to the welding beam and the reinforcement by the up and down driving cylinder, the left and right adjustment cylinder, the rotating cylinder and the slewing gear, and the upper and lower magnets and the reinforcement pressure cylinder are mounted on the lower end of the welding beam. Thermal girder saddle fixed hydraulic cylinder is used, and post-heat welding beam is operated by servo motor along linear rail of pre-heat and post-heat girder connecting frame to enable synchronous control and individual control of both ends by ball screw. It is driven and adjusted by cylinder and feed motor, and welding head is composed of up and down cylinder, guide roller and welding torch.

And the welding earth device is elevating by the up and down driving cylinder and energizing welding current, and the reinforcing material aligning device is composed of hoist crane, bogie, magnet and guide bar. It is possible to provide a welding device that can arrange two reinforcements at the same time and automatically weld them by dividing it into two areas and allowing individual control.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows the shape of the abacus and the reinforcement to accurately mount the mounting line of the abacus (M) and the reinforcement (S) in the present invention in order to mount the reinforcement (S) to the irregular shape of the abacus (M) and to allow the right angle and degree It is possible to provide an automatic reinforcement mounting device for shipboards to automatically mount the two rows of reinforcement (S) to the main plate (M) simultaneously without the occurrence of welding defects while maintaining the interval within the range.

The reference beam is aligned with the reference beam, and the welding beam rotating cylinder 22 rotates the welding beam 2 along the slew-in gear 23 so that the inclined reinforcement S can be adjusted so that the welding beam 2 can be mounted. The lower magnet 18 can be used to magnetize the reinforcing material (S). When the height of the reinforcing material (S) is high, the upper magnet (19) can magnetize the reinforcing material (S). The reinforced reinforcement S was brought into close contact with the main plate M to use the reinforcement pressure cylinder 17 to remove the gap therebetween.
