Solution Overview
Problem
Numerical control rotary tables with single dimensions are inadequate for handling parts of varying sizes and accuracy requirements, as they cannot efficiently switch between different machining tasks.
Innovation Solution
A nested numerical control rotary table system integrating a large and small rotary table, with a lifting oil cylinder, positioning pins, and guide rails, allowing convenient switching between the two tables to accommodate both large and small dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single numerical control rotary table is used, then the device complexity is reduced, but the adaptability to handle parts of varying sizes is insufficient
Solution Approach 1:
The patent applies nesting by placing the small rotary table inside the large rotary table structure. The small rotary table board is positioned within the large rotary table board, allowing both tables to coexist in a compact configuration. This enables the system to handle both large and small parts with a single integrated device, improving adaptability without proportionally increasing device complexity.
Solution Approach 2:
The patent creates a universal rotary table system that can perform multiple functions by integrating both large and small rotary tables. The system can switch between handling large parts on the large rotary table and small parts on the small rotary table, making the device versatile enough to accommodate varying part sizes and machining requirements.
2Adaptability or versatility
If multiple numerical control rotary tables with different dimensions are used, then the adaptability is improved, but the device complexity and space occupation increase
Solution Approach 1:
By nesting the small rotary table within the large rotary table structure, the patent significantly reduces the space occupied compared to having separate rotary tables. The small rotary table board fits inside the large rotary table board, creating a compact integrated system that maintains adaptability for different part sizes while minimizing floor space requirements.
3Adaptability or versatility
If multiple numerical control rotary tables are used, then the adaptability is improved, but the time required to switch between different tables increases
Solution Approach 1:
The patent implements preliminary action through pre-positioned positioning pins and positioning holes that are already in place before switching is needed. The positioning pins on the large rotary table board align with positioning holes on the small rotary table board, allowing for quick and accurate switching without requiring complex alignment procedures or significant setup time.
Solution Approach 2:
The nested configuration allows the small rotary table to be readily accessible within the large rotary table structure. This compact arrangement reduces the distance and time required to switch between tables compared to separate, dispersed rotary tables, enabling faster transition between handling large and small parts.

AI summary
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.
