The utility model relates to the technical field of engraving, and discloses an engraving scriber convenient for marking, which comprises a concave frame, the right side of the concave frame is in threaded connection with a screw rod, the left end of the screw rod penetrates through the concave frame and is rotatably connected with a linear module sliding table through a bearing, and the moving end of the linear module sliding table is fixedly connected with a positioning frame. By arranging the convex disc, the electric air cylinder, the driving frame, the rotating motor and the pressing disc, carving materials can be conveniently pressed, held and limited, meanwhile, the carving materials can be conveniently rotated, and by arranging the concave frame, the screw rod, the linear module sliding table, the positioning frame, the sliding plate, the positioning pipe, the marking pen, the spring and the guide assembly, the carving materials can be conveniently positioned. The marking height of the marking pen can be conveniently and vertically adjusted, meanwhile, the marking pen is buffered when being subjected to concave-convex extrusion of materials, the marking pen is prevented from being damaged, and by arranging the structure, marking use can be facilitated, so that the use requirements of customers can be met, and the carving precision is prevented from being influenced.

This utility model discloses a welding device for the assembly production of iron components, including a welding table, a moving table, a welding head, a moving assembly, a stacking frame, anti-slip plates, an extrusion assembly, a limiting plate, and a limiting assembly. The moving table is movably mounted on top of the welding table. The welding head is raised and lowered on the upper side of the moving table via a drive assembly. The moving assembly is installed between the moving table and the welding table. The stacking frame is slidably mounted on top of the moving table via a push seat. Two anti-slip plates are provided, moving towards each other on the stacking frame. Anti-wear pads are fixedly connected to the sides of the two anti-slip plates that are close to each other. Multiple extrusion assemblies are respectively installed between the stacking frame and the two anti-slip plates. The limiting plate is raised and lowered between the two anti-slip plates. The limiting assembly is mounted on the limiting plate, and a shock-absorbing pad is fixedly connected to the bottom end of the limiting plate. This welding device for the assembly production of iron components facilitates improved stability when welding multiple stacked iron components.
