Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, specifically a stainless steel bearing seat welding device. Background Technology

[0002] A bearing housing is the base for mounting and supporting bearings. It is a separate component that provides a precise and stable mounting position for the bearing, thereby supporting the rotating shaft, bearing the radial and axial forces from the shaft, and transmitting these forces to the machine's foundation or frame. It usually has built-in sealing devices to prevent lubricant leakage and the ingress of external contaminants. Unitizing the bearing makes the installation, adjustment, and maintenance of the entire bearing system much easier.

[0003] Meanwhile, the publicly disclosed (announcement) number CN214444206U is a welding device for processing bearing housings, including a side fixing component and a through-hole fixing component. The side fixing component is fixedly disposed above the through-hole fixing component and is used to fix the side of the mounting sleeve. The through-hole fixing component passes through the mounting sleeve for fixation. The side fixing component includes a first fixing rod and a first moving rod. The first moving rod can slide on a first support rod. The through-hole fixing component includes a second fixing rod and a second moving rod. The second moving rod is slidably disposed on a second support rod, through which the mounting sleeve passes. During use, the aforementioned welding device for processing bearing housings requires operators to manually position the bearing housing components, which can easily lead to positioning deviations and affect subsequent assembly and use. In addition, it lacks a targeted cooling structure and requires natural cooling after welding, which not only prolongs the production cycle but may also cause product scrap due to deformation.

[0004] Therefore, a stainless steel bearing housing welding device is proposed to address the above problems. Utility Model Content
