Description

Technical Field

[0001] This utility model relates to the field of centerless lathe chuck technology, specifically to a quick-change sizing multi-tool cutting centerless lathe chuck mechanism. Background Technology

[0002] A centerless lathe is a machine tool that can machine cylindrical workpieces without a center hole or center support. It is widely used for efficient and precision machining of shafts, tubes, and bars. Its core clamping mechanism, the centerless lathe chuck (or "centerless clamping device"), differs from traditional lathe chucks (such as three-jaw chucks). It mainly relies on guide wheels, support tool post, and clamping mechanism to achieve workpiece positioning and rotation. Currently, traditional centerless lathe chucks adopt an integrated "tool head-tool holder" design. Under high-speed cutting conditions, the wear rate of the tool head is significantly higher than that of the tool holder. Since the tool head cannot be replaced separately, the entire tool holder must be discarded during maintenance. Therefore, a quick-change sizing multi-tool cutting centerless lathe chuck mechanism is proposed. Utility Model Content
