Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, in particular to a production device for a precision bearing ring or a bearing. Background Art

[0002] A bearing is a mechanical element used to support rotating or linear motion, reducing friction and improving efficiency. Bearing rings are a key component of a bearing and are typically divided into inner and outer rings. Their primary function is to provide a smooth surface on which rolling elements (such as balls or rollers) can move freely, thereby reducing friction and supporting rotational or linear motion.

In traditional bearing ring turning, the bearing rings are mostly fixed on the positioning mechanism first, rotated at high speed, and then the outer side of the bearing ring is turned using a turning tool head.

[0059] In this way, synchronous turning of the inner and outer sides of the bearing ring blank 9 is achieved, the turning efficiency of the bearing ring blank 9 is improved, and the overall processing efficiency of the bearing ring is effectively improved;

[0060] Among them, by setting the first rotating mechanism 2 and the second rotating mechanism 3, it is convenient to position the bearing ring blanks 9 with different inner diameters, thereby facilitating the synchronous turning processing of the bearing ring blanks 9 with different inner diameters on both the inside and outside, thereby increasing the flexibility of the entire production equipment.
