Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a universal continuous casting roller bearing seat inner hole correction tool design. Background Art

[0002] During the use of the continuous casting roller bearing seat, after long-term wear, the inner hole becomes oval, causing the bearing to get stuck during operation, affecting the normal use of the bearing seat, shortening the service life of the continuous casting roller, and causing the roller to be offline early. To address this situation, the inner hole of the bearing seat is repaired by welding in the early stage, and then the machine is processed after welding to achieve the purpose of repairing the inner hole oval. During the subsequent assembly, high points appear in the inner hole, and the high points are polished to ensure the normal installation of the bearing. When repairing the inner hole of the bearing seat with this method, the welding amount is large, and welding defects such as pores and slag inclusions are prone to occur during welding, resulting in deformation of the bearing seat after repair welding, affecting the subsequent processing of the inner hole of the bearing seat. After continuous practice and exploration in production, a more practical bearing seat inner hole correction tooling has been designed. This correction tooling uses a hydraulic cylinder and an auxiliary fixture to squeeze the inner hole of the bearing seat to achieve the effect of correcting the bearing inner hole.
