Description

Technical Field

[0001] This utility model relates to the field of machining turntable technology, and in particular to a machining turntable for CNC machining centers. Background Technology

[0002] A CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system, suitable for processing complex parts. When a workpiece is processed in a CNC machining center, it needs to be supported, placed, and rotated to facilitate subsequent CNC processing. Therefore, a rotary table is added to the CNC machining center.

[0003] In actual use, the machining turntable of existing CNC machining centers requires the constant disassembly and assembly of clamping devices to hold the workpiece during the machining process, which is not conducive to improving the workpiece machining efficiency.

[0004] A search of existing patents revealed a machining rotary table for a CNC machining center (publication number: CN221658709U). This machining rotary table for a CNC machining center features five gripper mechanisms and one cam mechanism. The cam is slidably connected to the slots of the cam by a connecting piece, and the chuck is connected to the rotary table via a screw thread. This allows the rotary table to drive the chuck to rotate. The cam mechanism is fixedly connected to the worktable and engages with the chuck. Consequently, the gripper mechanisms automatically clamp and release the workpiece along the trajectory of the slots in the cam, achieving automatic clamping and releasing in multiple positions and improving machining efficiency.

[0005] Although the aforementioned patent achieves automatic clamping and releasing in multiple stations, the machining turntable of the CNC machining center needs to be selected according to the size of the workpiece, and the placement area of ​​the machining turntable is limited, which makes it difficult to improve the adaptability of the machining turntable.
