The present invention relates to a torch control device in the construction of a welding device for multi-electrode fillet automatic welding.

The automatic welding device is a generic term for the submerged arc welding (SAW) and gas metal arc welding (GMAW) techniques, which adopts the method of continuously supplying the consumed electrodes (wires). Assemble the long paper (angle, T-bar, plate bar, etc.) on the plate to automatically fillet welds on both sides at the same time as the weld seam line, or joints, formed between the plate and the long paper. As a dedicated automatic welding device for welding, place welded object (abacus, long paper) on the conveyor line in the workplace, and operate the automatic welding device to be located on the welded object to move the self-propelled welding carriage to match the weld line of the welded object, Set to the fillet welding object to match the optimum welding condition (distance, angle, position) of the welding torch, and ground the welder and the workpiece to be welded. When the corresponding switch on the operating panel mounted on the ridge is activated, the self-propelled welding carriage continues the welding while tracking the welding line of the welded object.

During welding, the torch's arc point (or welding center point) causes irregular welding line deviation, causing welding failure.

Factors such as mechanical structure, problems in the accuracy of the mechanical structure, the limitation of the traceability of the weld line of the guide roller method, the change in the linear feedability of the welded wire, the accuracy of the processing of the welded object and the arc instability.

The present invention is to adjust the distance of the torch as a rack and pinion type adjusting screw on the torch carriage rod installed on the torch arm to enable the position of the arc point of the torch during welding in order to obtain a good welding quality product. As the torch left and right adjustment screw, the arc point is adjusted to the required position of the welding line of the welded object, and the jaw-o type engagement bracket is used to adjust the arc point more precisely. It is possible to provide the required arc point by adjusting the distance between the guide roller for welding seam tracking and the torch and the distance between the leading torch and trailing torch in order to achieve optimal welding. To 80 ~ 120㎜ and use for tracking the trailing torch of right welding carriage and welding line of left welding carriage. The interval between de roller to be able to carry out welding by best adjusted to 40 ~60㎜.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A rack and pinion type torch spacing adjusting screw (1,1 ') is installed on the torch carriage rod (2), connected to the torch arm (A), and a slider and screw type torch up and down adjusting screw (3) (3') and Torch left and right adjustment screw (4) (4 ') adjusts the X and Y axes, and the roughness-corrugated recess 5a is formed in engagement with the recess 6a of the bracket 6, and the torch holding lamp is at the tip. (5b) is a bracket (5) formed to adjust the welding progress side direction angle, and the uneven portion (6b) is formed in engagement with the uneven portion of the bracket (10) provided on both sides of the torch up and down adjustment screw (3) (3 '). The distance between the guide rollers (7) (7 ') for welding line tracking of the right welding carriage (C) and the left welding carriage (C') and the preceding torch (T) by adjusting the welding progress length angle with the bracket (6). H), the distance H between the leading torch T and the trailing torch T 'in the range of 80 to 120 mm and the trailing torch T' and the left welding carriage C 'of the right welding carriage C. Guide roll for welding seam tracking It is the structure which adjusted the space | interval H of the claw 7 'to 40-60 mm.

Unexplained numeral 8 is the abacus and 9 is the long paper.

The present invention has been made in the case where the gap between the leading torch (T) and the trailing torch (T ') is incorrect when the arc point (welding center point) is irregular or deviates from the welding line before or during the welding work. Adjust the torch spacing adjusting screw (1) (1 ') installed on the torch carriage rod (2) to precisely adjust the spacing between the torch and the X axis (left, right) and Y axis (up, down) of the torch are defective. In the case of torch left and right adjusting screw (4) (4 ') and torch up and down adjusting screw (3) (3'), adjust the torch's X, Y axis, and if the torch's tip welding angle is bad, The side angle is the uneven portion 5a of the bracket 5 on which the torch holding clamp 5b is formed and the uneven portion 6a of the bracket 6 are interlocked with each other in a co-orthogonal manner to unscrew the central bolt to engage the uneven portion ( 5a), (6a), that is, adjust the lateral angle by holding the bracket (5) and adjusting it to the top or the bottom. And uneven portion 6b of the bracket 6 and the uneven portions of the bracket 10 installed on both sides of the torch up and down adjusting screws 3, 3 'are mutually co-orthogonal to each other. In the same way as in the welding progress longitudinal angle can be adjusted.

That is, the uneven part 6a of the bracket 6 is engaged with the uneven part 5a of the bracket 5 to adjust the side angle, and the uneven part 6b of the bracket 6 has the torch up / down adjusting screw 3 (3). ') Is engaged with the uneven portion of the bracket 10 installed on both sides in a jaw-oh manner to adjust the longitudinal angle.

By adjusting the torch with the above-mentioned multifunctional adjusting screw and bracket, the arc point of the welding torch can be easily and accurately adjusted under any circumstances, and in order to weld the optimum welding quality, the guide roller for welding line tracking (7) (7 ') and the preceding The torch (T) and the distance (H) between the leading torch (T) and the trailing torch (T ') are maintained within the range of 80 to 120 mm, and the trailing torch (T') and the left welding carriage (C) of the right welding carriage (C) By maintaining the distance H 'of the guide roller 7' for welding seam tracking of C ') in the range of 40-60 mm, favorable welding of a to-be-welded object is attained.

Therefore, the present invention is a multi-functional multi-function torch adjusting device that responds to the change of arc point that can occur before welding or during welding, allowing the operator to easily and safely adjust and perform automatic welding in the shortest time. Therefore, the welding work of the best to be welded is automatically performed, thereby reducing the labor.
