Description

Technical Field

[0001] The utility model relates to the technical field of connecting components, in particular to a detachable arc striking and extinguishing device. Background Art

[0002] Steel structures are widely used in construction and industry due to their high strength, lightweight, and excellent seismic resistance. Welding is a common joining method in steel structure fabrication, with arc welding being one of the most common welding techniques. During arc welding, the arc striking and arc extinguishing stages are crucial to the formation and quality of the weld.

[0003] Traditional arc striking and arc extinguishing operations often rely on the operator's skills and experience. During welding, long-term hand operation can easily lead to a cheap welding position, which may cause unstable quality of the starting and ending parts of the weld, affecting the appearance and mechanical properties of the weld, and at the same time, low welding efficiency. Therefore, it is necessary to design an arc striking and arc extinguishing device that can improve efficiency and ensure the stability of the welding position. Utility Model Content

An adjusting mechanism is provided on the base body, which comprises a first adjusting mechanism and a second adjusting mechanism. The positioning welding of the arc striking plate is realized by the first adjusting mechanism and the second adjusting mechanism. The welding position is adjusted by the adjusting mechanism to ensure the accuracy of the welding position, improve the welding efficiency, reduce the error caused by manual operation, and improve the welding quality.

[0008] Furthermore, the first adjustment mechanism includes a fixed frame arranged on the first base, a permanent magnetic adsorption unit connected to the fixed frame, and a control switch. The opening and closing of the permanent magnetic adsorption unit is controlled by the control switch, and the opening and closing of the permanent magnetic adsorption unit is controlled by the control switch to achieve adsorption and detachment of the steel structure, thereby preventing the arc striking plate from being displaced during welding and affecting the welding effect.

[0009] Furthermore, the second adjustment mechanism includes a second adsorption unit arranged on a second base body, and the second base body is provided with at least two positioning grooves for installing the second adsorption unit. The second adsorption unit moves along the positioning groove to adjust the distance between the two second adsorption units to facilitate the application of steel components of different thicknesses. At the same time, the setting of the limit groove limits the moving trajectory of the second adsorption unit and improves the stability of the movement.

[0010] Furthermore, an adjustment hole communicating with the positioning groove is opened on the second base body, and the adjustment member passes through the adjustment hole and abuts against the second adsorption unit. The second adsorption unit is locked by the adjustment member, achieving a double locking effect to ensure the quality of welding.

[0011] Furthermore, the second adjustment mechanism includes a chuck arranged in the positioning groove, which moves along the positioning groove. The connection position between the chuck and the steel component is adjusted by moving the chuck. The two chucks cooperate to clamp the steel component to lock the position, which facilitates the subsequent welding of the arc-starting plate.

[0012] Furthermore, a positioning hole is provided on the second base, and a connecting piece is installed in the positioning hole. The connecting piece passes through the positioning hole to connect to the chuck. The chuck is adjusted up and down by rotating the connecting piece, which makes it easier for the chuck to be used for steel components of different thicknesses and improves applicability.

It can form an isolation layer in the welding area to reduce or eliminate the adhesion phenomenon generated during the welding process.

[0051] The first base 11 is provided with a limiting groove 24 which is communicated with the installation groove 25. The limiting groove 24 is used to install the arc-striking plate 35 or the arc-extinguishing plate, which simplifies the installation process and improves the installation efficiency.
