Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and in particular relates to an arc welding device for steel gate ribs. Background Technology

[0002] To improve the bending resistance, impact resistance, and structural load-bearing stability of the steel gate after processing, a set of reinforcing steel plates is welded to the backwater side of the steel gate during the processing. The joints of the reinforcing steel plates and the connection between the reinforcing steel plates and the gate plate are welded and fixed together by arc welding, so that the reinforcing steel plates and the gate plate can form a stable load-bearing whole.

[0003] Shielded metal arc welding (SMAW) is the most widely used welding method in industrial production. It involves using the metal to be welded as one electrode and the welding rod as the other. When the two electrodes are brought close together, an electric arc is generated. The heat generated by the arc discharge (commonly known as arc combustion) melts the welding rod and the workpiece together, and after solidification, a weld is formed, resulting in a strong joint. The tip of the arc welding torch is a welding clamp used to hold the welding rod. The free end of the welding rod is aligned with the joint between the gate panel and the rib plate for welding and fixation. However, the gate panel and rib plate are vertical structures and quite long, making them prone to deviation during manual welding, resulting in misaligned welds. Therefore, this invention mainly addresses the problem of weld misalignment that easily occurs during the welding process of arc welding due to the long length and narrow welding space. Utility Model Content

[0004] The purpose of this utility model is to provide an arc welding device for steel gate ribs, mainly addressing the problem of misaligned welds that easily occur during the arc welding process due to the long length and narrow welding space of the welding end.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An electric arc welding device for steel gate ribs includes a welding clamp, which has a front clamping part for clamping and fixing the end of the welding rod, and a handle at the tail of the welding clamp;

[0007] An open collar is installed on the lower side of the handle;

[0008] It includes two positioning plates, which are set at 90°. The adjacent sides of the two positioning plates are separated. The two positioning plates are connected by a connecting rod, which is used to allow the collar to be inserted and to allow the welding clamp to rotate.

[0009] Furthermore, the collar is composed of arc-shaped clamping arms on both sides, with grooves inside the clamping arms, allowing for deformation.

[0010] Furthermore, a roller is installed on the sliding side of the positioning plate, and the side of the positioning plate has a folded edge with a shaft hole for installing the roller shaft.

[0011] Furthermore, the connecting rod has a limiting plate at the corresponding collar engagement position, and the limiting plate is adjustablely mounted on the connecting rod. The connecting rod has a threaded portion, and the limiting plate is annular with a nut fixed to the inner ring side, the nut being fitted onto the threaded portion.

[0012] This invention offers the following advantages: During use, positioning plates on both sides ensure the welding clamp holds the welding rod in the center, allowing for accurate positioning of the weld seam at the electrode end. The electrode then slides along the inner wall of the gate panel and rib. Because the positioning plates maintain a constant direction of movement during sliding, the welding rod moves in a straight line, preventing weld deviation. The welding clamp is detachably mounted on the connecting rod, facilitating disassembly and assembly. The clamp and connecting rod are adjustable to compensate for electrode wear during welding.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figure 1-3 As shown: The arc welding device for steel gate ribs includes a welding clamp 1. The welding clamp 1 has a front clamping part for clamping and fixing the end of the welding rod 2. The tail of the welding clamp 1 is a handle; the handle is used for hand operation, and the rear end of the handle is a wiring groove.

[0020] An open collar 3 is installed on the lower side of the handle; it is in the form of a U-shaped groove.

[0021] The system includes two positioning plates 4, which are set at 90° to each other. The adjacent sides of the two positioning plates 4 are separated and connected by a connecting rod 5. The connecting rod 5 is used to insert the collar 3 and to allow the welding clamp 1 to rotate. The end of the connecting rod is fixed to the back plate of the positioning plate, forming an integral structure with the two back plates. The connecting rod is used for detachable installation of the collar, and the collar can be rotated around the connecting rod as an axis.

[0022] During use, the welding clamp is positioned using the positioning plates on both sides to ensure that the welding rod is centered after being held by the clamp. The end of the welding rod can accurately position the weld seam. Then, it slides along the inner wall of the gate panel and rib plate. During the sliding process, the position of the positioning plates remains constant, allowing the welding rod to move in a straight line and preventing weld seam deviation. The welding clamp is detachably installed on the connecting rod for easy disassembly and assembly. The welding clamp and connecting rod are adjustable to compensate for the consumption of the welding rod during the welding process.

[0023] like Figure 1 The collar 3 shown consists of two arc-shaped clamping arms on both sides, with grooves inside the clamping arms for deformation. During the collar insertion process, the clamping arms on both sides are deformed and locked in place to prevent it from falling off.

[0024] A roller 41 is mounted on the sliding side of the positioning plate 4. The side of the positioning plate 4 has a folded edge 42, and the folded edge 42 has a shaft hole for mounting the roller 41. There are multiple rollers, which are arranged in a row along the moving side of the positioning plate to improve the smoothness of the sliding of the positioning plate.

[0025] like Figure 2 The connecting rod 5 shown has a limiting plate 6 at the corresponding collar insertion position. The limiting plate 6 is adjustablely installed on the connecting rod 5. The installation position of the limiting collar is adjusted according to the welding position so that the end of the welding rod can accurately position the weld. The connecting rod 5 has a threaded part 51, and the limiting plate 6 is annular with a nut 61 fixed on the inner ring side. The nut 61 is fitted onto the threaded part 51. The position of the limiting plates on both sides is adjusted by rotating the nut.

[0026] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
