The present invention relates to an automatic welding device that can automatically weld double-sided fillet welding, H-beam welding, etc. with two electrodes simultaneously. It allows the welding part to be welded precisely and consistently by being closely folded and moved, and it is possible to simplify the use by forming a complex of 2 lines of welding cables generated from two welding main bodies into one. It aims at streamlining and eliminating arc instability.

Conventional automatic welding device not only can not weld on both sides at the same time when double-sided fillet welding or H-beam welding, but also because the closely contacted and not moved, it was not possible to accurately weld to the welding site and to form a constant welding bead, especially curved, When welding the inclined curve and vertical part, it was more difficult to weld. The wire feed roller is constructed by coating metal on the outer surface with insulator and processing guide groove to insulate the wire and feed motor. Due to the need to form a tooth in the groove when feeding the soft wire, the groove was formed by the wire tooth, so that the wire feeding ability is bad and there was a closed end of arc instability.

The present invention has been devised in view of the above, and will be described in detail based on the accompanying drawings as follows.

In the automatic welding device for installing the feed roller (3) (3 ') in the upper portion of the trolley (2) that proceeds in conjunction with the motor (1) to supply the wire (4) supplied from it to the torch (5) Section on the lacking part 6 (6 ') formed in both side walls of the trolley | bogie 2 The guide rail 7 of the shape is vertically inserted, and the guide rails 8 and 8 'are inserted and inserted freely up and down, and the guide rails 9 and 9' are placed on the lift bar 8 and 8 '. Deformation <<< / RTI > The support rollers 11 and 11 'are installed in the lower guide section 9' and adhered to the pin 10 so as to be shaped, and the upper and lower transverse sections 8 have the tip inside the tip of the trolley 2. The operation lever 12 of the rear end which has been bonded is fitted to the operation plate 14 of the c-shape to adjust the height by fitting the control plate 13, and the operation lever 12 is operated to move the lifting lever 8 and 8 'up and down. The torch holder in which the torch 5 and the torch 5 is inclined so as to move left and right on the lifting side 8 of the upper side and at the same time the roller 17 is installed on the lower part 16 elastically installed with the spring 15. The two welding cables 20 and 20 ', which are fitted with height adjustments to 18 and connect the welding bodies 19, 19' and the feed cart 2, are shown in FIGS. 5 and 6 Come with help The second welding power supply line 22 is installed outside the center of the hose 21 and is covered with the insulating sheath 23, and the operation control line 24, the motor power supply line 25, and the first welding are again outside. The power supply line 26 is formed of a composite cable 28 coated with an outer shell 27, and the feeding roller 29 for supplying the wire 4 is composed of a ceramic material having excellent insulation and abrasion resistance. 2 to 3 U-shaped grooves 30 and 30 'and the wheels 31 cover the metal wheels 32 with rubber 33 or coil the coils 34 therein to electromagnet wheels 31. ′) Is designed to facilitate welding of inclined surfaces or curved sections.

In the figure, reference numeral 35 denotes a control box, 36 denotes a chain gear fixed to the drive shaft 37, 38 denotes an operation handle of the clutch 39, 40 denotes a welded object, 41 denotes a connection terminal, and 42 denotes a chain.

The present invention thus achieved by operating the motor (1) to rotate the drive shaft 37 via the chain 42, the bogie (2) proceeds to the rotation of the wheels 31 (31 ') that is stuck to the bar example Listen When welding the to-be-shaped welded object 40, as shown in the solid line in FIG. 3, the trolley 2 is positioned, and the operation lever 14 is moved up and down by the operation of the operation lever 12 as shown in FIG. By adjusting the upper lifting transverse (8) connected to this by operating the lower guide interval (9 ') because the guide interval (9) (9') bonded to the deformation <shape is widened or narrowed around the pin (10). The support rollers 11 and 11 'adhered to the &lt; RTI ID = 0.0 &gt;)&lt; / RTI &gt;

Therefore, according to the size of the interval between the welded object 40 according to the size of the lifting lever operation of the operation lever 14 by the operation lever 12 to raise and lower the upper and lower transverse spaces 8 to adjust the support rollers 11, 11 ′ Is completely in contact with the object to be welded 40, the trolley 2 proceeds in a state in which the support rollers 11 and 11 ′ are completely in contact with the object to be welded 40.

In addition, the torch 5 is also inserted into the torch holder 18 so that the height can be adjusted, so that the welding is performed after adjusting the height of the torch 5 to facilitate welding, and then lowering the torch holder 18. The roller 17 is placed on the welding is made in accordance with the progress of the bogie 2 in a state in which the roller 17 is spread over the vertical plane and the horizontal plane of the welded object 40, and the lower end 16 of the torch holder 18 is a spring 15. Since the torch is elastically installed so as to elevate along the welding surface of the to-be-welded object 40, the torch 5 is lifted on the basis of the torch holder 18 along the welding surface, so that welding is performed accurately.

Also When welding the welded object 40 in the shape, the support rollers 11 and 11 'must protrude out of the cart 2 to be in close contact with the welded object 40. In this case, the torch attached to the lifting leg 8 After the holder 18 and the torch 5 are separated, the lifting leg assembly 8 having the support rollers 11 and 11 'attached thereto is removed from the guide rail 7 and the imaginary line shown in FIG. Likewise, the support rollers 11 and 11 'are turned so as to face the outside of the trolley 2, and are inserted into the guide rails 7 and the torch holder 18 is attached, and then the operation lever 12 is operated as described above. If the support rollers 11 and 11 'are brought into close contact with the object to be welded 40 by adjusting the lifting and lowering of the operation 14, the trolley 2 can be accurately carried out while being constantly transferred without shaking sideways.

The welding cables 20 and 20 'are composed of two welding power sources, a gas hose and a motor operating power source, and a composite cable 28 having a control line necessary for operation as shown in FIG. According to the convenience of welding, the welding cable is not stretched loosely, so that the welding can be simplified.

The composite cable 28 is formed as shown in FIG. 6A described above, or even when the motor power supply line 25 and the operation control line 24 are simultaneously incorporated in the second welding power supply line 22, without any defect in function. This is possible.

In addition, the feed rollers 3 and 3 'which feed the wire 4 are formed of a ceramic material having excellent insulation and abrasion resistance, and U-shaped grooves are formed on the outer surface so that soft and hard wires can be simultaneously fed. It is not necessary to use different feeding rollers (3) (3 ') for soft and hard as in this case, and because the friction coefficient is large, the feeding of the wire 4 is smooth and the wire 4 is not scratched. There is no fear of this happening.

In addition, since the wheels 31 and 31 'cover the rubber 33 on the outer surface of the metal 32 and have excellent adhesion, the wheels 31 and 31' can be moved safely and the trolley wheels can be moved by electromagnetic force as the electromagnet wheels 31 '. When (2) is bonded to the object to be welded 40, there is an advantage that welding is possible on curved surfaces, curved portions, and the like.

In this way, the present invention is to be able to proceed along the welding surface by bringing the bogie (2) in close contact with the object to be welded (40) can not only ensure the accuracy of the welding work, but also to form a constant welding bead as a composite cable (28) Welding can be simplified and the feeding roller 29 can be improved by improving the feeding roller 29.
