The X-axis drive unit 100 includes an X-axis direction rail 110, an X-axis drive body 120, and an X-axis drive roller 130. Here, the X-axis direction does not refer to a particularly limited direction, but defines any one direction on the horizontal plane of the ship shell.

X-axis direction rail 110 is a commonly used rail installed in the X-axis direction on the vessel outer plate, serves to guide the drive in the X-axis direction of the automatic vessel shell character automatic welding device according to the present invention.

The X-axis direction rail 110 may be installed by arbitrarily adjusting the length to fit the working environment. That is, in the case of welding the characters located on the flat plate of the ship shell plate, the length of the X-axis direction rail 110 can be installed to be stretched by the length of the letter welding portion on the ship shell plate, in this case ship shell plate automatic welding according to the present invention The device can move and weld the entire section of the character weld on the ship's outer shell automatically. On the other hand, in the case of welding the characters located on the curved portion or the interference member of the outer shell of the ship it is virtually impossible to install the X-axis rail 110 as much as the size of the character, in this case, as shown in FIG. After installing only the X-axis direction rail 110 as long as the width corresponding to the width of the X-axis drive body 120 and attaching and fixing the X-axis drive body 120 thereon of the Y-axis guide 210 to be described later It is desirable to be able to weld characters without driving in the X-axis direction using only rotational and linear motions.

X-axis driving body 120 provides the power to enable the ship shell character automatic welding device according to the invention to move on the X-axis direction rail 110, this X-axis driving body 120 is for driving It will have a rack pinion gear and a motor.

The X-axis driving roller 130 is driven on the X-axis direction rail 110 in a state where the X-axis driving body 120 is mounted on the top. That is, when the rack pinion gear is operated in conjunction with the motor of the X-axis driving body 120, the X-axis driving roller 130 is driven while moving forward or backward on the X-axis direction rail 110.

At this time, the tension device 140 is mounted between the X-axis driving body 120 and the X-axis driving roller 130 so that the X-axis driving roller 130 can firmly hold the X-axis driving body 120. It is preferable. By the tension device 140, the X-axis driving body 120 may not only move on the X-axis direction rail 110 but also may drive the X-axis direction rail 110 without shaking.

Done.

When the Y-axis driving body 220 pushes or pulls the Y-axis guide 210 in a linear direction, welding is performed in the Y-axis linear direction by a welding torch 320 to be described later on the letter welding portion on the ship shell. At this time, when the Y-axis driving body 220 pushes or pulls the Y-axis guide 210 in a linear direction and the X-axis driving unit 100 moves forward or backward in the X-axis direction, The character welding part is welded in the diagonal direction or the curved form of the XY plane by the welding torch 320 to be described later. On the other hand, when the Y-axis drive body 220 rotates the Y-axis guide 210, the welding of the letter on the outer shell plate is made of a circular welding by the welding torch 320 to be described later.

The Z-axis driving unit 300 includes a Z-axis guide 310, a welding torch 320, and an automatic torch height control device 330. Here, the Z-axis direction means a direction orthogonal to the horizontal plane of the ship shell.

In addition, the Z-axis driving unit 300 collects and analyzes the signals generated from the sensors measuring the output current and the voltage, and evaluates the welding state of the weld in real time. More preferably). If the welding quality monitoring device (not shown) sounds an alarm, the welding torch 320 automatically stops the welding operation. In this case, the operator is malfunctioning or the welding of the ship shell is automatically performed. You can check the condition of the surface and make the welding work again normally. As a result, the ship shell welding part can maintain a high quality welding state.

The controller 400 electrically controls the operations of the X-axis driver 100, the Y-axis driver 200, and the Z-axis driver 300.

The controller 400 may exist in the form of a remote controller that performs a computing function. The controller 400 transmits job data such as text information and welding conditions, and generates a job report by DB by welding the job status. On the other hand, the current work status is displayed in real time. As a result, the operator can grasp the current welding progress from time to time through the control unit 400 so that the work can be performed more quickly and easily.

On the other hand, the present invention, in order to solve the problem that it is impossible to install the X-axis direction rail 110 as long as the size of the letter in the case of welding the character located in the curved portion or the interference member of the ship shell, X-axis It further presents a device that can be welded only by the operation of the Y-axis drive unit 200 and the Z-axis drive unit 300 in a fixed state without separately driving in the direction.
