Description
Technical Field
The utility model relates to the technical field of spot welding, in particular to an adjustable spot welding protection device.
Background
Spot welding is a welding technique that uses a cylindrical electrode to form a weld between the contact surfaces of two overlapping workpieces. In the spot welding process, the work is brought into close contact first by applying pressure, and then an electric current is conducted. Under the action of resistance heat, the workpiece contact point is melted rapidly and a firm welding spot is formed after cooling. The welding method is particularly suitable for welding sheet members and stamping parts with the thickness of below 4mm, and is widely applied to manufacturing of automobile bodies, carriages and aircraft fuselages.
During welding, the metal of the weld zone expands due to heat, but is constrained by surrounding unheated metal, creating compressive stresses within the weld zone. When the weld is completed, as the metal cools and contracts, the weld area develops tensile stresses due to the surrounding metal constraints. This constant change in stress is a major cause of weld distortion, and conventional welding modes often suffer from large thermal deformations and difficult dimensional tolerances to control. Meanwhile, in the use process of the conventional welding device, the welding piece is required to be clamped and fixed, and the clamp cannot adjust the position of the welding piece in the use process, so that the welding device can only weld the same position of the welding piece, the clamp cannot be moved to weld the objects at multiple positions, the use is difficult, and the welding efficiency is low.
In order to effectively control welding deformation, the fixture and the tool are particularly important to fix and restrain welding parts. These anchor clamps and frock not only can provide stable support for the welding in the welding process, prevent that it from producing too big deformation, can also help realizing the evenly distributed of stress. For example, in handling long welds, a tensioning device may be used to secure the weld in a predetermined position to reduce bending and distortion that may occur during the welding process.
Therefore, how to effectively control the deformation caused by welding and adapt to the variability of the shape of the welded part has become a technical problem to be overcome by those skilled in the art.
