Description

Lens polishing is little axle construction of integration for lower hem machine

Technical Field

The utility model relates to the technical field of lens polishing equipment, in particular to an integrated small shaft structure for a lens polishing and swinging machine.

Background

The lower swing machine is a lens polishing device of an optical instrument.

The pressure shaft 01 presses the small shaft 02, and the small shaft 02 presses the clamp on the swing type base.

As shown in fig. 2, the structure of the current small shaft 02 is mainly: the small-shaft-core-type rotating bushing comprises a small-shaft core 001, a large nut 002, a lining body 003, a first rotating bearing 004, a small-shaft outer sleeve 005, a small nut 007 and a small-shaft inner sleeve 009, wherein the small nut 007 presses the small-shaft outer sleeve 005 and the small-shaft inner sleeve 009 downwards and drives the small-shaft outer sleeve 009 to press the first rotating bearing 004, the lining body 003 is in threaded connection with the small-shaft core 001, and the lining body 003 supports the first rotating bearing 004 from the bottom.

When the component small shaft 02 is used, the bottom of the pressure shaft 01 is fitted into the gap between the large nut 002 and the liner 003. When the part staff 02 is required to be detached from the pressure shaft 01, the detached staff 02 needs to be installed again, the pressure shaft 01 is detached from the gap, the staff shaft core 001 on the staff 02 can shake, and when the staff 02 is installed on the pressure shaft 01 again, the coaxiality between the staff shaft core 001 and the pressure shaft 01 can generate a large error, so that the quality of polishing operation is affected.
