Abstract
The invention provides a nested numerical control rotary table, which comprises a large numerical control rotary table, a small rotary table, a large rotary table board and a small rotary table board nested in the large rotary table board, wherein the small rotary table board may be driven by the large numerical control rotary table as a part of the large rotary table board to run together with the large rotary table board, or be driven by the small rotary table to run independently. When the small rotary table board runs independently, the small rotary table is driven to ascend by a lifting oil cylinder, and a pull pin under the small rotary table board and a positioning pin on the small rotary table fixedly connect the small rotary table board with the small rotary table, which are locked by a clamp. The nested numerical control rotary table may complete the tasks of numerical control rotary tables with both large and small dimensions, which saves the production cost and improves the working efficiency. Moreover, switch between the large rotary table and the small rotary table is convenient, so time is saved.
