In general, welding is a technique for joining two or more members to be welded to each other. The welding is generally classified into gas welding, oxygen welding, and arc welding. In particular, It is well known that a welder capable of mutually joining while supplying a welding wire is widely used.

Recently, the use of automatic welding robots or carriages has been increasing due to the enlargement of process lines and automation, and the frequency of welding work by manual work has been reduced. However, In the block assembly process, automation welding works using the automatic welding robot and the carriage as described above can not be performed due to various shapes of the hull block.

In particular, when the operator performs a welding operation for a long time on a hull block having a large variety of shapes, the weld defect is increased due to the poor adjustment between the welding torch and the welded material, and the operator holds a heavy welding torch There has been a problem of high work fatigue and exposure to the risk of musculoskeletal diseases since it is necessary to carry out welding work repeatedly for a long time.

Further, even if the welded members are welded in a bent state with a certain angle or in a narrow space without being arranged side by side on the same horizontal line, the automatic welding robot can not be used and a manual welding machine must be used. This also keeps the spacing between the manual welder and the welded member constant and makes it difficult to weld.

1 is a perspective view of a welder supporting apparatus according to the present invention, in which a welding machine is mounted.

2A and 2B are views showing a method of operating a welding apparatus supporting apparatus according to the present invention.

FIGS. 3A and 3B are use state diagrams of a welding apparatus supporting apparatus according to the present invention.

Referring to FIGS. 1 to 3, a general manual welding machine 10 includes a handle 12 and a torch head 11 connected thereto.

The manual welding machine 10 may be mounted on the welding machine supporting apparatus 100 according to the present invention so that uniform welding can be performed while maintaining a constant distance between the welding torch head 11 and the members to be welded.

The welded members are arranged such that their edges or faces are adjacent to each other for welding, and the welded members are arranged such that the ends and ends of the welded members 1a and 1b, as in the embodiment of FIG. 3A, The end portions between the welded members 1a and 1b and the side surfaces of the body portions are arranged so as to be in contact with each other to perform butt welding.

At this time, the joints abutted between the welded members 1a and 1b arranged to be adjacent to each other become a root on the welded portion, and when the welded members 1a and 1b are welded to each other, 3A, they may be arranged on a horizontal line as shown in FIG. 3A, but may be arranged in a bent state at a certain angle as in the embodiment of FIG. 3B.

Referring to FIG. 3B, in the case where the contacted edges or faces between the disposed workpieces 1a and 1b form a narrow space of 90 degrees or less, the approach of a general automatic welding robot is not easy, The welding route is moved according to the operation ability of the operator using the welding machine, and the torch head 11 of the welding machine performs the welding operation.

However, since the manual welding machine depends on the operation ability of the operator, it is not easy to perform the welding while keeping the gap g between the manual welder and the welded member constant. Particularly, when the operator performs a welding operation on a hull block having a large variety of shapes for a long time, it is difficult to always keep constant the gap (g) between the welding torch head and the welded portion, Worker fatigue also increases.

However, if the welder supporting apparatus 100 according to the present invention is welded to the existing welder 10, even if the angle between the welded members is small and the approach of the welder is difficult, By keeping the gap and the speed at which the welder moves, uniform welding is possible and welding quality can be improved.

1 to 3, a welder supporting apparatus 100 according to the present invention is inserted and disposed in a space between welded members 1a and 1b disposed adjacent to each other,

Welder fixture (110);

A support member 120 provided at both sides of the welder fixing unit and including a latching hole 121;

An angle adjusting member 130 which is connected at one end to the locking hole 121 by the fixing means 131; And

And a guide roller 140 provided at the other end of the angle adjusting member 130,

At least one of the guide rollers 140 is engaged with the gear assembly 150 and driven.

The fixing means 131 includes a fixing bolt and a nut that are inserted into and coupled to one end of the angle adjusting member 130 and the locking hole 121 of the supporting member 120 at the same time. It is optionally possible to fix or release the angle adjusting member 130 to the engaging hole 121 of the supporting member 120 through the fixing means 131. [

The angle adjusting member 130 is fixed to the desired position of the fastening hole 121 formed in the longitudinal direction of the support member 120 by the fastening means 131 so that the fastening member 110 And at the same time, the angle adjusting member 130 is configured to be rotatable and fixable to the support member 120 according to a desired angle.

Referring to FIG. 2B, in the fixing unit 131, one end of the angle adjusting member 130 is coupled to the holding hole 121 of the supporting member 120, and the angle adjusting member 130 So that the support member 120 is selectively rotated or fixed.

More specifically, the fixing means 131 is normally inserted into the one end of the angle regulating member 130 and the engaging hole 121 of the supporting member 120 to be hinged and fixed, The fixing means 131 may be fixed to the supporting member 121 by tightening the fixing means 131 inserted into the fixing hole 121 after the position and the rotation angle of the angle adjusting member 130 are adjusted appropriately, 120 so as to be firmly fixed to the locking hole 121 of the locking member.

2A, the angle adjusting member 130 is not only rotated or fixed at the locking hole 121 of the supporting member 120, but also the angle adjusting member 130 is fixed to the supporting member 120 The total length (height) between the support member and the angle adjusting member can be adjusted as a result of adjusting the position at which the engaging hole 121 is engaged at a predetermined point.

For this, it is preferable that the retaining hole 121 of the support member 120 does not have a circular hole shape corresponding to the diameter of the bolt but the lateral width corresponds to the diameter of the bolt, but the longitudinal width is formed to be long in the longitudinal direction of the support member Do.

That is, since the hooking hole 121 is formed in a long hole shape along the longitudinal direction of the support member, the one end of the angle adjusting member 130 inserted by the fixing means 131 inserted into the hooking hole 121, The hinge shaft of the fixing means is moved without being fixed so that the angle adjusting member 130 can be fixed on the support member 120. [ As a result, not only the angle formed by the support member 120 and the angle regulating member 130, but also the overall length (height) is adjusted (see FIG.

The fixing means 131 is inserted into one end of the angle adjusting member 130 and inserted into the locking hole 121 of the supporting member 120 so that the fixing member 131 One end of the angle regulating member 130 is mutually flawed in the engaging hole 121 of the member 120. The position of the angle regulating member 130 coupled to the engaging hole of the supporting member 120 The angle adjusting member 130 and the angle adjusting member are adjusted to adjust the overall length (height) of the angle adjusting member 130 and the angle adjusting member 130. Then, the adjusting member 130 and the angle adjusting member 130 are rotated about the hinge axis of the angle adjusting member 130, The angle adjusting member 130 can be firmly fixed to the supporting member by tightening the fixing means 131. [

The one end of the angle regulating member 130 is hinged to the fixing hole 131 of the supporting member with the fixing unit 131 so as to be rotatable around the hinge axis, The hinge shaft can be moved along the fastening hole 121 formed in the longitudinal direction of the support member.

Therefore, the angle adjusting member 130 is appropriately positioned at a predetermined position of the supporting member 120 along the locking hole 121, as well as the angle of the supporting member and the angle adjusting member is adjusted by the fixing means 131 It is adjustable in total length (height) and can be fixed.

Although the fixing means 131 includes bolts and nuts in the embodiment of the present invention, the fixing means is not limited to bolts and nuts in the present invention, Any device capable of repeatedly fixing and releasing the ball 121 and one end of the angle adjusting member 130 can be applied as the fixing means of the present invention.

In order to facilitate understanding of the description of the present invention, in the embodiment of the present invention, the support members 120 provided on both sides of the welder fixing portion 110 are respectively supported by the first support member 120a and the second support member 120a, The angle adjusting member 130 connected to the member 120b and the first and second support members may be also referred to as a first angle adjusting member 130a and a second angle adjusting member 130b. Similarly, the fixing unit for coupling the first support member 120a and the first angle adjusting member 130a is referred to as a first fixing unit 131a and the second supporting member 120b and the second angle adjusting member 130b may be fixed to each other, May be referred to as a second fixing means 131b.

The guide roller provided on the first angle adjusting member 130a is referred to as a first guide roller 140a and the guide roller provided on the second angle adjusting member 130b is referred to as a second guide roller 140b .

Next, a description will be made of an operation process of the welder supporting apparatus 100 equipped with the welding machine 10 according to the embodiment of the present invention.

3A and 3B are views for explaining a welding process using the welding apparatus supporting apparatus 100 according to the present invention.

3A and 3B, a welding apparatus supporting apparatus 100 according to the present invention is mounted on a welded portion between welded members 1a and 1b while supporting the welder 10, Is supported and guided along a welding route so as to have a constant speed and a constant spacing (g) so that a uniform welding operation can be performed.

More specifically, the first and second angle regulating members 130a and 130b are respectively connected to the first and second supporting members 120a and 120b, respectively, while the welding machine 10 is fixedly mounted on the welder fixing unit 110 ) By the first and second fixing means 131a and 131b, respectively.

Meanwhile, the welding torch head 11 is disposed between the first and second angle adjusting members 130a and 130b and between the first and second guide rollers 140a and 140b, that is, The first guide roller 140a, the welder torch head 11, and the second guide roller 140b are sequentially disposed on the left and right sides of the torch head 11, respectively, as the guide rollers 140a, As shown in FIG.

The first and second guide rollers 140a and 140b are in contact with the surface of the welding route so as to be in close contact with the welding route surface of the welding torch 11, And then rolls along the welding route path in the same direction as the welding direction of the torch. That is, in the embodiment of the present invention, the guide roller and the welding torch head are conveyed along the weld root surface.

3A and 3B, among the sequentially arranged guide rollers, the second guide roller 140b guides the welding route first, followed by a welding machine disposed at the rear of the second guide roller 140b, The torch head 11 is welded along the welding route and then the first guide roller 140a is also transported along the welding route so that the welder torch head 11 is not out of the welding route path and uniform welding .

The first and second guide rollers 140a and 140b which are rolled while abutting the welding route between the welded members 1a and 1b are respectively disposed on both the left and right sides of the torch head 11, A uniform spacing g is always maintained between the torch head 11 and the welding route so that the welding operation can be performed uniformly even if the welding route is not deviated from the welding route.

On the other hand, contrary to the embodiment of FIGS. 3A and 3B, the welder support apparatus 100 is turned over by 180 degrees so that the first guide roller 140a guides the welding route first, and the torch head 11 and the second It is of course possible that the guide roller 140b is disposed to perform welding.

In order to achieve a more uniform and accurate welding operation, the distance d1 perpendicular to the welding route plane A from the welder fixing unit 110 to the end of the torch head 11 is set to be shorter than the distance d1 between the welder fixing unit 110 A distance d2 perpendicular to the welding route surface A from the welding roller 14 to the guide roller 140 is formed to be longer than the welding route surface A of the torch head 11 It is preferable to maintain a predetermined spacing g between them (see Fig. 2A).

3A and 3B, in the welder supporting apparatus 100 according to the present invention in which the welding machine 10 is mounted and fixed, the first and second guide rollers 140a and 140b are welded The torch head 11 of the welder is relatively short in distance d perpendicular to the welding route surface A while pressing the welding route in a state of being in tight contact with the welding route surface A of the member 1, The end portion continuously keeps the predetermined spacing g from the welding route surface A, so that uniform welding is possible.

Meanwhile, in the welder supporting apparatus 100 according to the present invention, the first and second angle adjusting members 130 may be spaced apart from one end of the angle adjusting member toward the other end. That is, the first and second guide rollers 140a and 140b (or 140a and 140b) are spaced apart from each other by a distance between one ends of the first and second angle adjusting members 130a and 130b connected to the first and second support members 120a and 120b The first and second angle adjusting members 130a and 130b may be spaced apart from each other.

3A and 3B, the torch head 11 of the welding machine disposed between the first and second angle regulating members 130a and 130b follows the welding route of the welded members 1a and 1b And the welding bead is formed at the time of welding. At this time, the welding bead is welded between the workpieces to be welded (1a, 1b) 11 may contact the second guide roller 140b located at the rear side of the first guide rollers 11, the welding quality of the welded portion may be affected.

Therefore, in order to prevent the second guide roller 140b from being disposed too close to the torch head 11 of the welder so as not to affect the weld quality of the welded portion of the welded member 1 in the embodiment of the present invention, It is preferable that the other end portions of the first and second guide rollers 140a and 140b are spaced apart by a predetermined distance. The adjustment of the spacing width may be performed by rotating or fixing the angle adjusting member 130 from the supporting member 120 through the fixing means 131 as described above (see FIG. 2B).

Referring to FIG. 2B, when the first and second angle adjusting members 130a and 130b are coupled to the first and second supporting members 120a and 120b at a predetermined angle, Can be adjusted to more than 180 degrees. Therefore, when the direction of the welding route changes rapidly instead of maintaining the straight line, for example, in the space of the member to be welded having the shape of 'A' or 'C', the fixing means 131 is loosened, The torch head 11 is easily moved to the welded portion at a position where the welding route direction is rapidly changed and is moved away from the welded portion at a constant distance, .

Next, the first and second guide rollers 140a and 140b are placed in a root path, which is a weld joint between the members to be welded 1a and 1b, .

On the other hand, in order to obtain a good welding quality, it is important to keep the welding speed constant as well as to keep the distance g between the welding torch head 11 and the welding root surface of the workpiece constant.

Therefore, in the embodiment of the present invention, at least one of the first and second guide rollers is coupled to the gear assembly 150 driven by the motor M to be driven at a constant speed.

Since the rotational speed of the meshed gears is controlled according to the motor driving speed, the speed of the guide roller that rotates in association with the gear assembly 150 can be changed by adjusting the driving speed of the motor M. [ And can rotate at a constant speed ratio.

Meanwhile, the guide roller, which rotates in conjunction with the gear assembly 150, controls the direction and speed of the guide roller by a controller (not shown) Or the welder fixing part 110 described above.

In addition, in the embodiment of the present invention, the guide roller which is engaged with the gear assembly 150 and rotates at a constant speed is in the form of a toothed wheel. The reason why the guide roller is in the form of a toothed wheel is to increase the frictional force of the guide roller abutting the welding route surface of the member to be welded so that the guide roller in contact with the welding route surface does not slip out of the welding route path during the welding, It is to make it roll well at a constant speed.

In the embodiment of the present invention, the gear wheel and the gear assembly 150 are shown as being formed on the second guide roller 140b positioned in front of the welding torch head 11. However, The structure of the assembly 150 is not limited to the second guide roller 140b but may be configured on the first guide roller 140a located behind the welder torch head 11, It is of course possible to constitute both of the rollers 140b.

Further, with reference to FIG. 2A, it is also possible to reverse the feeding direction and speed of the guide roller by the operation of the above-described controller (not shown).

3A and 3B, the second guide roller 140b guides the welding route first, and the second guide roller 140b moves along the second guide roller 140b, The rear welder torch head 11 is welded along the welding route and then the first guide roller 140a is also transported along the welding route and the welder torch head 11 is gripped so as not to leave the weld root path It is possible to reverse the direction of the welding machine supporting apparatus 100. [0064] As shown in FIG.

That is, since the direction of the guide roller can be rotated in both directions by the controller operation, the first guide roller 140a in the direction opposite to the embodiment of FIGS. 3A and 3B can move the welding route Of course, it is also possible to guide the welding torch head 11 first along the welding route, and then welder support the welding torch so that the second guide roller 140b is guided.

Meanwhile, in the embodiment of the present invention, it is preferable that the support member 120, the angle regulating member 130, and the guide roller 140 are made of a relatively thin plate-like material. 3B, even when a corner or a face abutting between the members to be welded 1a and 1b forms a narrow space of 90 degrees or less, the welder support apparatus 100 according to the present invention is not limited to the welding route In order to facilitate access.

The welding apparatus supporting apparatus 100 according to the present invention configured as described above is configured to support the manual welder 10 and to set the spacing g between the end of the welding torch head 11 and the welding route surface of the workpiece to be constant And the welding speed is constantly guided. Therefore, uniform and excellent welding quality can be expected.

In addition, a narrow space of 90 degrees or less is formed between the welded members 1a and 1b so that the automatic welding robot can easily access and homogenous welding even if the robot is difficult to access.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
