Description

Technical Field

[0001] This utility model relates to a metal railing welding and fixing frame, specifically a metal railing welding and fixing frame, and belongs to the field of metal railing technology. Background Technology

[0002] A metal railing welding fixing frame is a specialized tooling device used to assist in the positioning and fixing of metal railing components. It typically consists of a rigid frame, an adjustable clamping mechanism, and a positioning reference surface. Its core function is to provide three-dimensional spatial positioning and rigid fixing of railing posts, crossbars, and other components through a multi-directionally adjustable mechanical structure, providing a stable spatial reference for welding operations. This ensures the relative positional accuracy between components, the fit of joints, and the quality of weld formation. This device effectively reduces manual positioning errors, minimizes welding deformation, improves work efficiency, and ensures the safety of construction personnel. It is particularly suitable for standardized welding operations of mass production or complex, irregularly shaped railing structures. Existing metal railing fixing devices cannot adjust the front-to-back distance between the railing and the horizontal bars. The width of the horizontal bars is often not the same as the width of the railing. If the front-to-back distance of the horizontal bars cannot be adjusted, the bars will often be in an asymmetrical position after welding. This not only affects the aesthetics of the railing but also its structural strength. This invention can effectively adjust the front-to-back position of the welded horizontal bars, thereby improving the aesthetics and structural strength of the railing, which has practical value. Utility Model Content

[0003] The purpose of this utility model is to provide a metal railing welding fixing frame to solve the above problems. It can effectively adjust the front and rear positions of the railing crossbars before and after welding, thereby improving the aesthetics and structural strength of the railing. This has certain practical value.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a metal railing welding and fixing frame includes an operating table. A fitting groove is provided in the middle of the top side of the operating table. Fixed vertical rods are fixedly connected to the bottom rectangular array of the operating table. A square base plate is fixedly connected to the bottom end of the fixed vertical rods. An electric push rod is fixedly installed in the middle of the bottom side of the square base plate.
