Both sides of the pinion gear with the pinion gear interposed so that a part of one side of the guide rail provided with the rack gear can be sandwiched between the pinion gear and the rack gear 103. Contact rolls 201 provided in pairs on the upper and lower sides, gap adjusting rolls 202 provided in pairs on the upper and lower sides of the gap adjusting block 203 arranged to be movable on the other side of the main body, and contact rolls; A gap adjusting means 204 provided at an arbitrary point of the main body (right end of the main body in FIG. 1) with one end coupled to the gap adjusting block 203 to adjust the gap between the gap adjusting rolls, and the rear of the main body; A support block 205 provided on the side of the support block, It is composed of a mounting plate 206 and a guide shaft 207 coupled in such a way that one end is exposed to the support block 205.

Moreover, the pinion gear arrange | positioned at one side of a main body part so that it may engage with the rack gear 103 is couple | bonded with the output shaft of the geared motor M shown in FIG. Therefore, when the geared motor M is driven, the pinion gear meshed with the rack gear 103 rotates, whereby the main body 200 of the traveling cart follows the guide rail 101 of the guide unit in a vertical direction (Fig. In 1, it rises or falls in the vertical direction).

In addition, the contact roll 201 and the space | interval adjusting roll 202 are arrange | positioned 4 pairs in total, one pair each in the upper and lower sides of the main body part 200, respectively. As shown in FIG. 3, these paired rolls are arrange | positioned in the form which becomes closer between rolls, as it approaches the both sides of the guide rail 101. As shown in FIG.

The gap adjusting blocks 203, which are provided with a pair of gap adjusting rolls at the upper and lower portions thereof, can be moved from the left side to the right side or the right side to the left side of the main body 200 by the operation of the gap adjusting means 204. Therefore, in accordance with the width dimension of the guide rail 101, the space | interval between a contact roll and a space | interval adjusting roll is adjustable. As a result, the assembly and disassembly of the guide unit A and the running cart B are performed by operating the gap adjusting means.

As the spacing adjusting means 204, for example, as illustrated in FIG. 1, a ball screw may be employed in which a knob is mounted at one end and a spacing adjusting block 203 is coupled to the other end. .

At a predetermined position of the mounting plate 206, for example, an angular bearing is installed in a form penetrating the mounting plate, or an axis that can be inserted into the inner ring of the angular bearing provided on a platform to be described later is provided, or such A hole is formed through which the shaft (or pin) can be installed.

A total of two support blocks 205 protruding from the rear of the main body are arranged on both sides of the lower surface of the mounting plate so that the mounting plate can be stably supported. However, the number of support blocks is not limited to this, and may be three or more, or may be one.

The support shaft 207 is fixed to the support block 205 in such a manner that one end (left end in FIG. 1) is exposed.

Composition of welding unit (C)

As illustrated in FIGS. 1 to 4, the welding unit C according to the present embodiment includes a welding work part having a torch 301 that can adjust welding posture, and the welding work part is provided at one end (in FIG. 1). Idle roller for tracking the weld deformation provided on one end side of the platform together with the platform 310, the angular bearing (311) is installed through the assembly point (left end side) and the interference with the welding work part does not occur 312, an arm 309 assembled on the other end side (right end side in FIG. 1) of the platform so as to be slideable with respect to this platform, and a main roller assembled on the other end side (right end side in FIG. 1) of this arm. It consists of 307.

Further, below the welding unit, there is a copper alloy assembly 400 and a copper alloy position adjusting slide 305 mounted to be slidably movable with respect to one end (left end in FIG. 1) of the guide shaft 207. It is arranged. In addition, these copper lactose assembly and copper lacquer position adjustment slides are fixed to each other, as illustrated, for example in FIG.

For example, as shown in FIG. 7, the welding work part includes a torch angle adjusting slide having a torch 301 having a torch tip T that becomes thinner toward the tip portion, and a torch fixing clamp 302. 306), a Z-axis torch positioning slide 303 in which a torch angle adjustment slide is assembled, and a Y-axis torch positioning slide 304 in which a Z-axis torch positioning slide is assembled, so as to enable a gap between the torch and the base material. Consists of a structure that includes. However, the welding work part is not limited to such a structure, and for example, the torch used in the conventional electrogas welding apparatus and the slide element which can adjust the welding angle and welding position of such a torch may be employ | adopted as it is.

1 and 3, the main roller 307 of the present embodiment further includes a tension adjusting element 308 for pushing the piston rod, which is provided with a roll in the front end portion, to the base material. The spring for pushing the rear end of the piston rod toward the front side is built in the tension adjusting element.

In addition, although the structure of the idle roller 312 may be the same as the main roller, the roll roller may be provided in the structure different from the main roller, for example, the edge part of the rod which does not have a tension adjusting element.

With this structure, there is a difference between the magnitude of reaction force received when the roll of the idle roller passes the welding deformation site and the magnitude of reaction force received by the roll of the main roller through contact with the base material, and the angle corresponding to the difference. Even if the platform is rotated on the mounting plate, the distance and angle between the torch and the welding improvement surface can be kept constant at all times without the roll of the idle roller and the roll of the main roller falling from the base material.

In addition, the copper lactose assembly 400 according to the present embodiment, as illustrated in FIGS. 5 and 6, is in close contact with the base material in a form spanning both base materials 600 with the welding improvement 610 therebetween. It comprises a sugar 410 and a copper sugar pressing means 420 for pushing the copper sugar to the base material side.

More specifically, the copper allowance 410 may include a cooling case 411 provided at a lower portion of a rear side of an inlet 412 through which a refrigerant flows in and a outlet 413 through which the refrigerant flows out, and a refrigerant inside the space of the cooling case. A plurality of flow control panels 414 protruding along the upper and lower surfaces of the inner space at intervals so as to flow in a zigzag and the upper side of the cooling case so that the opening width is enlarged from the rear side to the front side of the cooling case. It consists of a gas inlet 415 formed in. On the back of the gas inlet, a gas supply port 430 into which the gas supply pipe 440 is fitted is formed.

In addition, the same amount of pressing means 420, the cylinder 422 with a spring, and the cooling case is in close contact with the thin plate, that is, the base material 600, as the rear end fitted to the cylinder is pushed to the front side of the cylinder by the spring. It consists of a rod 421 to be.

On the other hand, before welding is performed, the backing material 700 is arrange | positioned along welding improvement in the form which faces copper lactose.

With this configuration, for example, as illustrated in FIG. 5, the protective gas supplied through the gas inlet 415 is concentrated near the molten pool, and is evenly distributed near the molten pool, thereby contacting the atmosphere. It is possible to prevent oxidation and nitriding of molten metal due to high efficiency.

In addition, since the refrigerant supplied into the cooling case 411 flows out while zigzag-flowing the inner space of the cooling case by the flow control plate 414, compared to the conventional copper equivalent without the flow control plate 414, The residence time of the refrigerant becomes long. For this reason, compared with the conventional copper sugar, the temperature of the refrigerant flowing in the zigzag in the cooling case 411 is slightly higher, and the temperature distribution becomes more uniform. As a result, it is possible to reduce the decrease in the welding strength due to rapid cooling by not supercooling around the welded portion where automatic welding is performed.

In addition, since the copper sugar 410 is located directly below the torch 301, it is possible to immediately respond to welding deformation generated when welding the base material 600 having a thin thickness. In other words, in accordance with the welding deformation of the weld, the copper allowance 410 and the torch 301 move in the same manner, the stable welding is performed.

In addition, this copper allowance can be adjusted in the width direction of the welding improvement 610 by the copper allowance position adjustment slide 304, and the base material 600 has an appropriate contact pressure by the copper allowance pressurizing means 420. Because it adheres to the surface of), it can prevent copper sugar from floating on the surface around the weld improvement. For this reason, both the bead width which arises when the weld part periphery overheats and the weld defect which arises when the weld part periphery is supercooled are suppressed, and the welding quality of a weld part improves.

In addition, when the roll of the idle roller 312 passes the welding deformation site, the platform 310 is rotated on the mounting plate 206, whereby a welding work assembled on one side of the platform 310 approaches the base material. Alternatively, the welding position of the torch 301 is automatically changed by rotating in the separation direction. As a result, even when the torch passes through the weld deformation site, an arc can be formed in the middle of the molten pool, so that beads of good quality can be obtained.

In addition, the torch 301 according to the present embodiment has a front end portion of the torch tip T through which the welding wire 800 having a diameter of, for example, 1.6 mm, is continuously supplied through the central passage, as shown in FIG. 7. Has been machined so as to have a constant inclination angle θ, so that the tip of the torch tip rarely comes into contact with the surface of the welding improvement, and the occurrence frequency of the arc stop phenomenon due to a short circuit is greatly reduced or the arc stop phenomenon itself occurs. Is prevented. For example, in thin plate welding, the width of the weld improvement formed between the two base materials is about 6 mm, whereas the tip diameter of the torch tip is about 5 mm and the maximum diameter at the longitudinal midpoint is about 9 mm.

In addition, in the present embodiment, the outer surface of the torch tip is coated with ceramic to prevent damage of the torch tip due to welding heat.

As described above, the thin-plate electrogas welding apparatus according to an example of the present invention can actively cope with welding deformation accompanying the thin-plate welding, and can track the weld seam. In addition, it is possible to prevent the position change of the torch tip due to welding deformation and the arc tipping phenomenon caused by this, and to obtain an excellent welding quality.

As described above, the configuration and the effect according to an example of the present invention have been described, but the above description is exemplary in all aspects, and the present invention is not limited thereto. It is understood that numerous modifications that are not illustrated may be assumed without departing from the scope of the invention.
