Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical processing, in particular to a core rod processing center sleeve. Background Art
[0002] A center sleeve is usually a component in the mechanical field. In some mechanical structures, the center sleeve plays the role of positioning, supporting and transmitting force or motion. It is generally installed in the center position of the shaft or other rotating parts to ensure the smoothness and accuracy of rotation. The center sleeve can reduce friction, prevent wear, and help maintain the correct alignment of the mechanical system.
[0003] The core sleeve currently used in core rod processing usually uses a threaded connection to fix the core rod, which can firmly fix the core rod inside the core sleeve and make the connection and removal of the core rod and the core sleeve relatively easy, thereby improving the production efficiency of core rod production.
[0004] The currently used core rod processing center sleeve can fix the core rod, but it cannot accurately adjust the width of the core rod, resulting in the center sleeve being able to connect and fix core rods of a specific size. This requires additional processing of core rods of different sizes, which increases processing costs and affects usage. Therefore, a core rod processing center sleeve is proposed to solve the above problems. Utility Model Content
