Description

Technical Field

[0001] The invention relates to the technical field of metal structure manufacturing, in particular to a clamping and fixing device for metal structure manufacturing. Background Art

[0002] Metal structures refer to the production activities of manufacturing metal components, metal component parts, steel products for construction and similar products with iron, steel or aluminum as the main materials. These products can be transported and are easy to assemble, install or erect. Metal structures include: metal structures for construction, components: metal roofs, metal roof frames, metal columns, etc., metal bridge structures and bridge parts, iron towers, iron frames, metal pillars, metal beams, metal frames at the entrance of mines, metal components such as sluices and docks, metal mobile houses, steel scaffolding, metal formwork or metal pillars for tunnel support and similar products, etc.

[0003] A clamping mechanism is required when manufacturing metal structures. By fixing and limiting the metal structure through the clamping mechanism, the accuracy of the metal structure manufacturing can be improved.

[0004] The announcement number is CN221516940U, a clamping and fixing device for metal structure manufacturing. When the user places the metal workpiece, the retractive force of the heavy-load spring can clamp the workpiece. When starting processing, the user places the acrylic transparent protective plate in the protective plate placement box and puts both hands into the square holes in the acrylic transparent protective plate. During the processing, the processing residue or debris will not splash on the user's face or clothes at will. At the same time, the transparent material of the acrylic transparent protective plate will not affect the user's vision. During the metal processing process, when the metal needs to be cooled, it can be directly cooled on the fixture through the water outlet pipe, which improves work efficiency.

[0005] There are still certain shortcomings in use. When in use, the four sides of the metal structure cannot be fully limited, and the clamping and stabilizing effect of the metal structure is limited. When the metal structure is manufactured, the metal structure may be accidentally loosened, thereby reducing the manufacturing effect of the metal structure and making the applicability of the clamping and fixing device poor. Therefore, we propose a clamping and fixing device for metal structure manufacturing. Summary of the invention

[0028] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the abutment plate 16 extends into the groove 20 and is slidably connected to the groove 20, the side end of the abutment plate 16 abuts against the surface of the movable plate 6, the top of the support plate 3 is fixedly connected with the top plate 8, the top of the top plate 8 abuts against the metal body 11, the metal body 11 is arranged on the side of the first limiting plate 7, the metal body 11 abuts against the surface of the first limiting plate 7, a stepper motor 19 is installed at the bottom of the top plate 8, the output end of the stepper motor 19 is fixedly connected with the threaded rod 13, the external thread of the threaded rod 13 is connected with the threaded sleeve 14, and the top of the threaded sleeve 14 is fixedly connected with the second limiting plate 12.

[0029] Among them, the first limit plate 7 and the second limit plate 12 can be driven to move under the power of the driving motor 17 and the stepping motor 19. The first limit plate 7 and the second limit plate 12 can clamp the four sides of the metal body 11, thereby improving the clamping stability of the metal body 11, avoiding accidental loosening of the metal body 11 during processing of the metal body 11, and improving the manufacturing accuracy of the metal body 11.
