Description

Technical Field

[0001] The utility model relates to the field of steel gratings, in particular to a positioning tool for processing steel gratings. Background Art

[0002] Steel grating, also known as steel grid plate, is a steel product made of flat steel arranged at regular intervals and crossbars, welded together to form a square grid. It is primarily used for gutter covers, steel structure platforms, and ladder treads. Crossbars are typically made of twisted square steel. Hot-dip galvanizing involves reacting molten metal with an iron matrix to produce an alloy layer, thereby bonding the matrix and the coating. Hot-dip galvanizing involves first pickling the steel parts to remove iron oxide from the surface. After pickling, the parts are then cleaned in an aqueous solution of ammonium chloride, zinc chloride, or a mixture of ammonium chloride and zinc chloride, and then placed in a hot-dip galvanizing tank. Hot-dip galvanizing offers advantages such as uniform coating, strong adhesion, and a long service life. Carbon steel steel grating often requires hot-dip galvanizing for corrosion protection and increased service life.

[0003] During the processing of steel grating, it is often necessary to use positioning tooling to fix the steel grating. However, the process of fixing the steel grating with the positioning tooling currently used for steel grating processing is relatively cumbersome, and the angle of the steel grating cannot be flexibly adjusted, resulting in low processing efficiency. Therefore, a positioning tooling for steel grating processing is proposed to address the above problems. Utility Model Content

[0014] 1. The utility model sets structures such as limit columns, limit plates, torsion springs, push rods, and movable plates. When in use, the steel grating is placed flat on the support plate, and the steel grating is supported by the support plate. At the same time, the torsion springs cause the limit plates on both sides to flip outward, so that the ends of the limit plates on both sides abut against the inner walls of the gap to limit the steel grating. In addition, the threaded rod is driven to rotate by turning the knob, thereby pushing the movable plate to move upward. The movable plate simultaneously drives the push rod to move upward, and the push rod moves upward until it abuts against the inner walls of the limit plates on both sides, so that the limit plates can be further tightened against the inner walls of the gap, so that the steel grating can be stably limited by the limit plates.

When in use, the rotating plate is driven to rotate by rotating the movable rod, and then the rotating shaft and the support plate are driven to rotate, so that the inclination angle of the support plate can be changed as needed, and the steel grating can be driven to adjust the angle, which is convenient for processing the steel grating. After the angle is adjusted, the movable rod is pushed inward so that the end of the movable rod is inserted into the limiting hole, thereby limiting the movement of the rotating plate, so that it can be kept at the adjusted angle position, which is convenient for processing.
