Description

Technical Field

[0001] This utility model relates to the field of machine tool processing, specifically an indexing and positioning device for a multi-station bearing seat milling machine. Background Technology

[0002] Slewing bearing housings are large and extra-large bearing housings with special construction that can accept comprehensive loads. They are characterized by compact structure, sensitive rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The internal support point of the bearing is the shaft, and the external support is the bearing housing. Since a single bearing can be fitted with different bearing housings, and a single bearing housing can be fitted with different types of bearings, there are many varieties of bearing housings. [Company Name] has a catalog of bearing housings, and many large international bearing companies also have their own bearing housing catalogs. Bearing housings require milling machines and indexing positioning devices for processing during production.

[0003] For example, in the indexing rotary positioning device described in (authorization announcement number CN210909235U), the workpiece rotary platform has an annular hollow structure, and the auxiliary indexing positioning device includes clamping blocks and positioning blocks.
