[0016] 1. For this steel structure automatic processing equipment, by setting replaceable model tools, different model tools can be replaced when processing different aspherical surfaces. By reciprocally pushing the model tools, the model tools grind the end face of the steel structure, making the arc surface ground on the end face of the steel structure smoother and more rounded.

[0017] 2. For this steel structure automatic processing equipment, by setting and using the clamping and fixing device for fixation, the device can be fixed at one end of the steel structure. By setting a rotatable model tool, the device can be fixed at one end of the steel structure to perform grinding processing on the steel structure, achieving the effect of processing the end face of the steel structure by fixing it on the outside of the steel structure, and solving the problem that the steel structure is too long to be processed on a traditional machine tool.

[0018] 3. For this steel structure automatic processing equipment, by setting an electric telescopic rod, the wrapping frame can drive the model tool to rise and fall in a timely manner, making the processing of the end face of the steel structure faster. By setting positioning sliders inside the wrapping frame, it is more convenient to clamp and fix the model tool.
