Clamping unit for work-piece positioned in center lathe, comprising pneumatic front chucks with radial movable gripping elements

摘要

The pneumatically operated front chucks (9), coaxial positioned with a flanged adapter (2) joined to the spindle (1), are fixed with an elastic coupling (11) and provided with at least two radial movable clamping elements (10). The elements (10) are driven by a pneumatically operated cylinder. Pressurized air is guided through the spindle (1) and through bores (13) in the adapter (2) resulting in the connection to a rotating intermediate flange (4) and to the front chucks (9).
