[0002] Bearing steel pipe refers to hot-rolled or cold-rolled (cold-drawn) seamless steel pipe for manufacturing ordinary rolling bearing rings. It is divided into ordinary precision and higher precision. The main raw material for manufacturing bearing steel pipe is bearing steel, which is divided into chromium bearing steel and chromium-free bearing steel. Bearing steel is used to manufacture balls, rollers and bearing rings. The requirements for the uniformity of its chemical composition, the content and distribution of non-metallic inclusions, the distribution of carbides, etc. are very strict. It is one of the most stringent steel grades in all steel production.

[0003] After searching, the applicant found that a Chinese patent disclosed "a fixing seat for processing bearing steel tubes", and its publication (announcement) number is "CN218556107U". This patent mainly reduces the instability of manual fixation of bearing steel tubes during welding, which causes deviation during welding and affects the use effect. At this time, the bearing steel tube is clamped by clamping plates on both sides, thereby increasing the fixing effect of the bearing steel tube during welding. However, the clamping position cannot be protected when clamped by the screw, and the steel tube is easily deformed when the inner wall of the steel tube is thin. For this reason, we propose a fixing seat for processing bearing steel tubes. Utility Model Content
