Description

Fillet welding carriage {Welding carriage for exclusively welding fillet}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weld carriage dedicated to fillets, and more particularly to a joint portion between a first base material oriented in a horizontal or curved shape and a second base material oriented perpendicular to the first base material. The present invention relates to a fillet-only welding carriage capable of selectively welding both uniformly or differently at once while moving both sides of a seam to be welded at a set speed during welding.

In general, welding in ships is one of the important processes that accounts for more than half of the overall shipbuilding process. The manufacturing process of a ship is made by independently manufacturing hull blocks of various shapes and then combining the hull blocks with each other in a dock.

However, the welding work essential during the ship manufacturing process is necessary for the automated welding to effectively cope with the job hunting and the aging trend of skilled welders due to 3D evasion due to the poor working environment (welding fume, spatter, welding heat, etc.). .

In particular, the welding operation required during the ship construction process involves a joint between the generally horizontally oriented base material (first base material) and the generally vertically oriented base material (second base material), that is, the member is orthogonal, such as T-shaped. Welding to the part to be made is essentially required.

However, the known fillet-only welding carriages to date have not been precisely targeted at the welded part because their driving is made on the upper surface of the substantially vertically oriented base material or the substantially horizontally oriented base material (see Patent Document 1).

In addition, the known fillet-only welding carriage to date has a limitation in that it is difficult to work when the horizontally oriented base material has a different shape, that is, an arc shape (refer patent documents 1 to 3).

Korean Utility Model Registration No. 20-0175956 (registered on Jan. 12, 2000, titled "Auxiliary device for horizontal or vertical mobile automatic welding device", Patent Document 1) Registered Korean Patent No. 10-1060004 (August 22, 2011, the name of the invention "carriage and automatic welding device having the same", Patent Document 2) Korean Utility Model Registration No. 20-0418906 (registered on June 8, 2006, titled "Driving and Weaving Control Structure of Fillet Welding Equipment", Patent Document 3)

The present invention has been made to solve the problems of the prior art, an object of the present invention is to weld the joint portion between the first base material oriented in a horizontal or curved shape and the second base material oriented perpendicular to the first base material. The present invention provides a fillet-only welding carriage that can be selectively welded to the same or different dimensions at a time while moving both sides of the welding target seam at a set speed in compliance with the inclination angle of the first base material.

It is another object of the present invention to move both sides of a seam to be welded at a set speed evenly at a time when welding a seam portion between a substantially horizontally oriented first base material and a base material oriented generally perpendicular to the first base material. An object of the present invention is to provide a fillet-only welding carriage that can be selectively welded to a dimension or to another dimension.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to the following illustrative drawings. In describing the present invention, a description of known functions or configurations will be omitted for the sake of clarity of the present invention. Also, like reference numerals denote like elements throughout the specification.

FIG. 1 schematically shows a rear view of a fillet-only welding carriage according to an exemplary embodiment of the present invention, and FIG. 2 schematically shows a frame configuration omitting some components of the fillet-only welding carriage shown in FIG. 1. 3 schematically shows a right side view of the fillet-only welding carriage shown in FIG. 1, and FIG. 4 schematically shows a frame configuration omitting some components of the fillet-only welding carriage shown in FIG. 3. Drawing. Above and below, the front or front, rear or rear, right side or right side, left side or left side of the expressions used together while referring to the entirety of the fillet-only weld carriage should be understood to be based on the direction of travel of this apparatus. do. For example, the back side of the weld carriage should be understood as the weld carriage advancing opposite the back side.

1 to 4, the fillet-only welding carriage according to an exemplary embodiment of the present invention includes a base frame 10, a pair of drive frames 30, a weld 50, and a controller.

As used herein, the term "first base material" refers to a base material that is generally horizontally oriented or curvedly oriented, and the "second base material" refers to a base material that is generally perpendicular to the first base material. That is, as shown in FIG. 1, the curved base surface shown by the dashed-dotted line or the rectangular base material shown by the solid line becomes the first base material, and is oriented perpendicular to the rectangular base material shown by the solid line. The base material shown by a dashed-dotted line becomes a 2nd base material. Accordingly, the term first base material used throughout this specification should be understood to include both horizontally oriented base materials and curved oriented base materials unless otherwise specified. In addition, the fillet-only welding carriage according to the present invention targets the joint portion between the first base material and the second base material for welding.

Referring back to FIGS. 1 to 4, a pair of drive frames 30 are mounted below the base frame 10 as shown. At this time, each drive frame (30a, 30b or 30) is mounted to be driven in a direction closer to or farther from each other by the operation of the handle 12 mounted on the right side in the drawing of the base frame (10). A more detailed description thereof will be given later.

When the driving wheel 32 is moved in a direction in which each driving frame 30 is closer to each other by the manipulation of the handle 12, the driving wheel 32 is closely aligned with both sides of the second base material and is generally vertically oriented. 2 The friction force on the side of the base material causes the welding carriage to be driven forward or backward. The driving wheel 32 is limited by the distance that each drive frame 30 is closest to each other, and horizontally by the force of the welding carriage itself and the force that is symmetrically close to each other. Even in the case of the first base material which is not oriented, for example, in a curved shape, the seam portion may be welded while maintaining a distance of the torch described below with respect to the seam portion between the first base material and the second base material. To be able.

In addition, each drive frame 30 is equipped with a weld 50 having a total of four torches 52, two each as shown. Here, the torch 52 is each configured to be selectively operated. That is, the torch 52 is configured to be welded selectively or simultaneously at both sides while moving either one seam portion, or both seam portions, of both seam portions of the generally vertically oriented second base material. For example, to weld only the seam portion on the right side of the seam between the first base material and the second base material, one or both of the torchs 52 mounted on the drive frame 30a on the right side of the figure. To weld the seam. Torch inclination angle in the welding portion 50 and the method for adjusting its position will be described later.

In addition, one lower caster, which is indicated by reference numeral 62, is mounted at the front and the rear of each drive frame 30, respectively, and a height-adjustable slide caster, which is indicated by reference numeral 64, indicates the caster 62. One outside and one outside each side). Detailed description of the height adjustment structure and the method for the latter slide caster 62 will be described later.
