Welding machine with roller guides {WELDER HAVING ROLLER GUIDE}

The present invention relates to a welding machine provided with a roller guide, more specifically, to maintain a constant distance between the nozzle and the base material to improve the welding quality, and to replace the roller corresponding to the shape of the base material, more precise welding work A welder provided with a possible roller guide.

In general, TG (Tungsten Inert Gas Welding) is a welding method of a welding structure, which is easy to work and requires high reliability for the formation of high-quality welded metal parts. It is widely used as a method of welding structures using stainless steel-base materials such as steel or stainless steel.

The welding torch 10 used in the conventional manual tag welding is provided in the torch body 20, the nozzle 30 provided at the end of the torch body 20, and the torch body 20 as shown in FIG. 1. A collet 40, a tungsten rod 50 fitted to the collet 40 and extending out of the nozzle 30, and a handle 60 extending from the torch body 20 and held by the user for holding. .

The conventional welding torch 10 is a welding operation while maintaining a distance spaced apart from the base material in a state in which the tungsten rod 50 is exposed to a predetermined portion at the end of the nozzle 30 during welding.

However, the conventional welding torch 10 has a problem in that welding is deteriorated due to difficulty in maintaining a constant distance from the base material because welding is performed in a state in which the worker grips the handle 60.

The present invention was devised to solve the above problems, by maintaining a constant gap between the nozzle and the base material to improve the welding quality, rollers can be replaced in response to the shape of the base material, which allows more precise welding work rollers It is an object to provide a welding machine provided with a guide.

According to an embodiment of the present invention for achieving the above object, in the welder consisting of a head portion formed at the tip of the handle and the nozzle portion extending up and down, and a welding rod inserted into the nozzle portion, the head A fixed block is formed on one side of the part, and the fixing block is provided with a space adjusting post capable of height adjustment up and down, and a guide roller is mounted at an end of the space adjusting post. A welder is provided with a roller guide detachable from the adjustment post.

The guide roller may have any one of a flat surface, a convex shape, and a concave shape.

The auxiliary roller guide may be disposed on the moving line of the guide roller and mounted on the other side of the head part to be spaced apart from the guide roller at a predetermined interval, and to adjust the height of the up and down.

The fixing block is detachable from the head portion, and optionally, the guide roller may be mounted on the head portion.

According to the present invention, the guide roller is attached to the head of the welder torch to maintain a constant distance between the nozzle and the base material to improve the welding quality, and to replace the roller corresponding to the shape of the base material, more precise welding work There is a possible effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a block diagram showing a welder provided with a roller guide according to an embodiment of the present invention, Figure 3 is an exemplary view showing various guide rollers of the welder provided with a roller guide according to an embodiment of the present invention.

The welding machine provided with the roller guide of the present invention as shown in Figure 2, the handle 100, the head portion 210, the nozzle portion 200, the welding rod 220, the fixing block 310, the post 300, and the roller for the guide 330.

The handle 100 is provided with an operation switch 110, the head portion 210 is mounted to the nozzle portion 200 vertically. In addition, the nozzle unit 200 may employ a conventional welding torch equipped with a welding rod 220. The welding torch may be a laser welding gun.

In the above configuration, the fixing block 310 may be mounted on one side of the head portion 210. At this time, the fixing block 310 is preferably mounted in a snap-fit (snap-fit) connection method to be detachable from the head portion (210).

Accordingly, the guide roller may be installed and used according to the working situation, or the user may easily use the guide roller from the head 210.

In addition, the post 300 is mounted on the fixing block 310 to be movable up and down, and the fixing nut 380 is mounted on one side of the fixing block 310 to raise and lower the post 300 in the fixing block 310. Can be adjusted or fixed at a predetermined position. On the other hand, the upper end of the post 300 may be provided with a ruler that is a measure of height adjustment.

Here, the guide roller 330 is mounted on the lower end of the post 300 so that the welder may slide in a straight line on the welding surface of the base material 400.

On the other hand, the guide roller 330 as shown in Figure 3 may be provided in various forms depending on the bonding form of the base material. Specifically, when the base material is butt welded or overlap welded on a plane as shown in FIG. 4A, a flat roller 330a may be provided, so that the welding can be stably performed while sliding along the welding surface of the base material 400. Do.

In addition, when the base material 400 is to be welded angled corners, such as butt welded at a right angle as shown in (b) of Figure 4, the concave roller 330b can be mounted as shown in (b) of FIG. Welding is possible while sliding the right-angled joint of the base material 400.

In the case of the fillet welding welded on the inside of the base material which is abutted at right angles in the state of FIG. 4B, a convex roller 330c as shown in FIG. 3C may be employed.

As described above, the various guide rollers 330 can be selectively mounted at the lower end of the post 300, so that the guide rollers 330 can be applied correspondingly according to the butt shape of the base material 400, thereby welding Work efficiency can be improved.

5 is a block diagram showing a welder provided with a roller guide according to another embodiment of the present invention.

According to another embodiment of the present invention, the auxiliary roller guide may be further provided in the above-described embodiment. In more detail, the auxiliary roller guide includes a second fixing block 360, a second roller 350, a second post 340, and a second fixing nut 380.

The second fixing block 360 may be mounted on the opposite side of the first fixing block 310 so that the first guide roller 330 and the second guide roller 350 may be spaced apart at regular intervals in the sliding direction. have.

In addition, as described above, the second fixing nut 380 may be formed to adjust the vertical height of the second post 340.

In such a configuration, the welder in the flat base material 400 may be prevented from sliding in a state inclined to one side. That is, the auxiliary roller guide can improve the stability of the welding by maintaining the horizontal state of the welding machine.

In addition, although not shown, the guide roller can be processed according to the shape of the joint of the various base material 400 can provide a smooth working environment according to the overlapping shape of the base material (400).
