AI Technical Summary

Technical Problem

Existing hot-wire method equipment suffers from problems such as cumbersome calibration, time-consuming operation, and poor stability due to the sliding base movement caused by the use of a slide rail.

Method used

The rotating imaging system is fixed with a base, a fixed support, rolling bearings, a rotating sleeve, a drive assembly, a support frame, a lifting assembly, an observation lens, and a counterweight. The rotation and lifting of the observation lens are achieved by a stepper motor, and the position sensor provides real-time monitoring and control to ensure precise alignment.

Benefits of technology

It enables flexible switching of observation lenses, improves operational efficiency and observation imaging quality, reduces equipment costs, and enhances equipment stability and positioning accuracy.

Abstract

The application discloses a rotatable imaging system fixing device for a hot-wire method and an observation method, and particularly relates to the technical field of metallurgical and high-temperature material experimental equipment, and comprises a base, a fixing column, a rolling bearing, a rotating sleeve, a driving assembly, a supporting frame, a lifting assembly, an observation lens, a furnace body and a counterweight. The fixing column is detachably installed on the base through bolts A. The inner ring of the rolling bearing is coaxially sleeved on the circumferential surface of the fixing column. The rotating sleeve is coaxially sleeved and fixed on the outer ring of the rolling bearing, and the rotating sleeve is connected with the fixing column through the driving assembly. The supporting frame is connected with the circumferential surface of the rotating sleeve through the lifting assembly. The observation lens is arranged on the supporting frame. The furnace body is arranged on the top surface of the base. The counterweight is fixed on the outer wall of the side of the rotating sleeve away from the supporting frame. The application has the advantages of reasonable structure, stable structure, high positioning precision and convenient operation, and effectively improves the experimental efficiency.
