AI Technical Summary

Technical Problem

The existing H-beam pre-assembly line end positioning mechanism is prone to causing the H-beam to collide with the rigid stop during high-speed conveying, resulting in vibration, noise, and even workpiece rebound or positioning deviation. It has poor repeatability and positioning accuracy and may damage the end face.

Method used

The system employs a track frame, web plate positioning assembly, and wing plate positioning assembly, combined with a negative pressure adsorption unit, a hysteresis damping unit, and an auxiliary clamping assembly. It uses photoelectric sensors to detect positioning, achieving flexible buffering and temporary fixation to ensure positioning accuracy and safety.

Benefits of technology

It effectively prevents poor positioning accuracy, avoids damage to the end face, achieves smooth buffering and no rebound, and ensures the accurate positioning and safe transportation of H-beams.

Abstract

This invention relates to the field of H-steel pre-assembly welding, and more particularly to an end positioning mechanism for an H-steel pre-assembly line. The mechanism includes a track frame, a web positioning assembly, and two sets of wing plate positioning assemblies. A movable support and a fixed support opposite to the movable support are respectively mounted on the track frame. The two sets of wing plate positioning assemblies are respectively mounted on the fixed support and the movable support. A web support is fixedly mounted on one side of the fixed support. The web positioning assembly is mounted on the web support. The web positioning assembly includes a web positioning support plate and a web baffle disposed on the side of the web positioning support plate. The wing plate positioning assembly includes a wing plate positioning support plate and a wing plate baffle disposed on the side of the wing plate positioning support plate. This invention provides a damping force proportional to the speed by adding a hysteresis damping unit at the floating stop, ensuring a smooth buffering process without rebound. This ensures that after the kinetic energy is lost, the stop near the conveying end face is completely in contact with the baffle end face, effectively preventing poor positioning accuracy.
