Description

Technical Field

[0001] The utility model belongs to the technical field of honing, in particular to a floating bearing inner wall honing tool. Background Art

[0002] Floating ring bearings can also be called floating sleeve sliding bearings (sometimes referred to as floating bearings). This type of bearing is based on the original radial sliding bearing structure, and one or more sleeves that can rotate freely between the journal and the bearing are added, turning the original friction pair into two or more friction pairs working simultaneously. Both sides of the floating ring sleeve are lubricated with oil.

[0003] According to the disclosure, a plunger hole floating honing processing device (publication number: CN 206855228 U) includes a base, support columns are arranged on both sides of the base, a longitudinal swing ring is arranged between the support columns, a transverse swing positioning hanging basket is arranged in the longitudinal swing ring, the longitudinal swing ring and the support column, the transverse swing positioning hanging basket and the longitudinal swing ring are hinged by a swing pin, an adjustment block is arranged between the base and the transverse swing positioning hanging basket, and a swing amplitude limiting gap is arranged between the adjustment block and the transverse swing positioning hanging basket. The utility model can be widely used in the honing of the middle hole of the plunger sleeve series products.

[0004] However, the above application has a base with support columns on both sides, a longitudinal swing ring between the support columns, and a transverse swing positioning basket inside the longitudinal swing ring. It is difficult to clean the grinding chips generated during the honing process, resulting in a lot of grinding chips on the workbench, affecting the honing effect, which needs to be improved.
