Description

[0001] An auto carriage for welding [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auto carriage for automatically performing edge welding or butt welding while moving along a welding line by using a driving wheel. More particularly, the present invention relates to an auto carriage in which a welding line has a straight line and a curved line, The present invention relates to an auto carriage capable of carrying out a welding operation without any error even in the case of a curved line having a curved line.

Ship or other marine structures are finished by assembling a unit structure by welding thick plates, various metal plates, and steel materials together. In particular, when the ship is to be dried, the vertical bulkhead structural member is welded to a metal bottom plate or the like to form a unit structure. In welding the structural members, the welding torch is moved along the edge line in the horizontal direction, Is an autoclave for welding.

As shown in FIG. 5, the conventional automotive carriage for welding has a configuration in which the bogie frame 10 is configured to be linearly movable only by the drive wheels 11, so that the welding line may have a straight line section and a curved section, In the case of only the curve section, there is a problem that the bogie frame deviates from the moving line without being properly adapted. A proposed technique for improving this problem is Korean Patent No. 0684617.

Korean Patent Registration No. 0684617 discloses a technique in which a rotary guide roller 70 provided with a plurality of rollers perpendicularly to the moving direction of a bogie frame is hinged to a front surface of a bogie frame 10, have. In this case, as the rotary guide roller tilts with respect to the hinge axis, even if the welding line has a certain curvature, the bogie frame can easily move along the surface of the welding member correspondingly thereto.

Korean Patent Registration No. 0684617 discloses a structure in which a fixing bar is hinged to a carriage frame while a plurality of rollers are mounted on a fixing bar having a predetermined length in constituting a rotary guide roller, . This is because, when the fixed bar is tilted, if any one of the opposite ends of the fixed bar comes into contact with the front portion of the bogie frame, the fixed bar can no longer be tilted.

In order to solve this problem in this technique, it is necessary to shorten the length of the fixed bar or increase the interval between the fixed bar and the bogie frame. However, in the case of the former, there is a certain limit in that the roller must be mounted. In the latter case, it is difficult to position the welding torch and it is difficult to apply the welding torch according to the size of the welding member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the technical features of the present invention, A detailed description thereof will be omitted.

FIG. 1 is a schematic perspective view of a welding automobile according to the present invention, and FIG. 2 is a schematic bottom view of a welding automotive carriage according to the present invention. As shown in the drawings, the present invention is characterized in that it includes a bogie frame 1, a guide frame 10, a guide wheel 20, a drive wheel 30 and a driven wheel 40. Each of these configurations will be discussed in detail.

The bogie frame 1 is a part to which various equipments such as the control box 2, the driving motor 3, the torch clamp 4, the welding torch 5 and the moving handle 6 are mounted, A rectangular frame having a receiving space is formed as a body frame of an automotive carriage for welding.

The control box 2 is provided on one side of the upper surface of the carriage frame 1 with various operation switches and cable connectors as means for controlling driving of the welding carriage. The drive motor 3 is provided on the upper surface of the bogie frame 1 adjacent to the control box 2 as means for providing a rotational force to the drive wheels 30. [

The torch clamp 4 may include a casing, a length adjusting knob, an angle adjusting knob, and a welding torch fixing means. In relation to this, the torch clamp 4 may be formed by a method disclosed in Korean Patent No. 1050047 and Korean Patent No. 1363736 And thus description thereof will be omitted. The welding torch 5 is placed on the torch clamp 4 at a predetermined angle downwardly inclined to the center of the upper surface of the truck frame 1 and its position can be appropriately adjusted by the torch clamp 4.

The movable handle 6 is a means for moving or adjusting the position of the auto carriage for welding. One end of the movable handle 6 is coupled to one side of the bogie frame 1 and can be rotatably mounted on the engaging shaft. The specific configuration of the movement handle is widely known in the related art, and a description thereof will be omitted.

The guide frame 10 may include a first guide frame 12 and a second guide frame 16 as means for mounting the guide wheel 20. The first guide frame 12 has a pair of ends, each one end portion of which is fixedly coupled to both sides of the cargo frame 1, and the other end portion extends forward of the cargo frame 1.

The second guide frame 16 is fixed at both ends thereof to the first guide frame 12 and is spaced apart from the front surface of the main frame 1 by a predetermined distance. Is positioned higher than the vertical height of the base plate (12). This is to exclude interference with the welding land 6. It is to be understood that the present invention can be made in a one-piece structure rather than a structure in which the guide frame is separated and joined to the first and second guide frames as shown in the drawing.

The guide wheel 20 is guided by the first guide wheel 22 and the second guide wheel 26 as a means for guiding the welding torch 5 to move appropriately along the welding line when the bogie frame 1 is moved .

It is preferable that the first guide wheel 22 is mounted on the central portion of the second guide frame 16 and the rotation axis thereof is located in the upper right room of one side of the welding torch 5. The second guide wheel 22 is spaced apart from the first guide wheel 22 by a predetermined distance and mounted on one side of the second guide frame 16. The first and second guide wheels 22 and 26 are preferably made of a metal having a predetermined thickness so as to prevent damage to the guide wheel itself due to high heat generated during the welding process.

In configuring the first and second guide wheels, it is preferable that the diameter of the first guide wheel 22 is larger than the diameter of the second guide wheel 26 as shown in the figure. This is for the purpose of bringing the bogie frame 1 into close contact with the vertical partitions of the welding member in accordance with the operation of the driving wheel 30, and the reason will be described in detail later.

If each guide wheel has the same diameter, it is possible to expect the same effect as that of the above-described configuration (for example, a V-shaped structure) by projecting the central portion of the second guide frame forward beyond both end portions. This is because, in this case, the rotation axis of the first guide wheel can be further projected forward than the rotation axis of the second guide wheel.

In addition, the present invention does not exclude the case where the permanent magnet 50 is provided between the first guide wheel 22 and the second guide wheel 26. When the permanent magnet 50 is added, the magnetic force caused by the permanent magnet acts on the vertical partition wall H of the welding member W as shown in Fig. 4, so that the guide wheel 20 is more closely contacted with the vertical partition wall It is possible to maintain the state.

The driving wheel 30 is a means for moving the truck frame 1 in a direction perpendicular to the welding torch 5 and includes first and second driving wheels 30, (32, 36). The first and second drive wheels 32 and 36 are preferably arranged to form a triangle with respect to the first guide wheel 22 with reference to the truck frame 1 as shown in FIG. Each of the first and second drive wheels 32 and 36 is driven by a drive motor 3, and their mutual connection configurations are well known in the related art, and a description thereof will be omitted.

The driven wheels 40 are composed of first and second driven wheels 42 and 46 spaced apart from each other by a predetermined distance, and are installed on the front surface of the truck frame 1. At this time, each of the first and second driven wheels 42 and 46 is connected to each of the first and second drive wheels 32 and 36 by a drive shaft, and each of the driven wheels is configured to rotate freely with respect to the drive shaft. The driving wheels may be fixedly coupled to one end of the driving shaft and the driven wheels may be rotatable on the other end of the driving shaft, or vice versa.

When the driven wheel is configured in this manner, it is driven by friction with the ground (or the bottom portion of the welding member) when the driving wheel is operated to move the bogie frame in one direction. The reason why the present invention proposes such a construction is that welding work can be performed even if the welding line has a curved section and a straight section or a curved section having various curvatures. This will be described in detail in the operation configuration to be described later.

The schematic operating configuration of the present invention will now be described with reference to the above-described description and to FIGS. 3 and 4 attached hereto.

When the welding member W is determined as an object to be subjected to the welding operation, the operator grips the moving handle 6 to move the welding automotive carriage (hereinafter, carriage) to the vicinity of the welding member, And is brought into close contact with the vertical partition wall (H). At this time, the second guide wheel 26 is spaced apart from the vertical partition H by a predetermined distance, and one end portion of the welding torch 5 mounted on the torch clamp 4 is inclined at a predetermined angle, As shown in FIG.

When the first guide wheel 22 is in close contact with the vertical partition wall H, the switch of the control box 2 is operated to operate the drive motor 3. When the drive motor 3 is operated, the rotational force is transmitted to the first and second drive wheels 32 and 36. The first and second drive wheels 32 and 36 are rotated in one direction by the transmitted drive force, It starts to move slowly.

Each of the first guide wheel 22 and the first and second drive wheels 32 and 36 is located at a triangular point with respect to the truck frame 1 and the first and second driven wheels 42 and 46 When the first and second drive wheels 32 and 36 are rotated while the first guide wheel 22 is in close contact with the vertical partition wall H, The carriage which has started to move in the direction ① is gradually rotated in the ② direction starting from the first guide wheel 22 and continues to rotate until the second guide wheel 26 is in close contact with the vertical partition wall H .

That is, the carriage does not linearly move in the solid line direction, but rotates in the direction of the dotted line with reference to the contact point between the first guide wheel and the vertical partition wall. When the second guide wheel 26 is brought into close contact with the vertical partition wall H and the first and second guide wheels 22 and 26 come into contact with the vertical partition wall H at the same time, the rotational movement of the carriage ends. Thus, the carriage, that is, the carriage frame 1 is in intimate contact with the welding member W. [ This state can be more easily maintained by the magnetic force acting on the vertical partition wall by the permanent magnet 50.

When the rotational force of the drive motor 3 is transmitted while the first and second guide wheels 22 and 26 are in close contact with the vertical partition wall H at the same time, each of the first and second drive wheels 32 and 36, Since the first and second guide wheels 22 and 26 are in close contact with the vertical partition wall H, the carriage is continuously moved in the ③ direction. At this time, the driven wheels 42 and 46 are inclined at the same angle as the first and second drive wheels 32 and 36. As the carriage moves separately from the rotation of the drive shafts 33 and 37, And frictionally rotates while rubbing against the bottom surface of the member (W).

When the carriage is brought into close contact with the vertical partition wall H and starts to move along the predetermined path, the welding torch 5, which is operated by the switch of the control box 2 and whose one end is spaced apart from the welding line L by a predetermined distance, To perform a welding operation on the welding line (L). Once the welding operation is initiated, the first and second drive wheels strongly urge the second guide wheel against the vertical bulkhead and continue to rotate, so even if the welding line is of a complicated structure as shown in FIG. 4, The welding operation can be performed without leaving the path.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be apparent that the present invention can be practiced with added features.
