Description

Technical Field

[0001] This utility model relates to the field of chuck technology, and in particular to a CNC indexing chuck for cylindrical workpieces. Background Technology

[0002] The indexing chuck is a new type of specialized fixture that can be widely used in CNC machine tools such as CNC lathes, mill-turn centers, and machining centers. It is particularly adept at machining multifaceted and complex parts on the same axis, combining clamping and indexing functions. This allows for multi-faceted machining with a single clamping operation; that is, the workpiece rotates automatically while the spindle is constantly rotating, reducing the number of clamping operations for workers, lowering labor intensity, and, more importantly, improving machining efficiency and workpiece accuracy.

[0003] However, the following defects or problems still exist when combining existing technologies: traditional indexing chucks are fixedly installed on the machine tool mounting base, and their height cannot be adjusted. When loading and clamping some larger pipes or straight rods, a support frame is used to transport the pipes to the chuck. Since the support frame and the pipes are of different sizes, the indexing chuck is inconvenient to clamp. Therefore, we designed a CNC indexing chuck for cylindrical workpieces.
