Solution Overview
Problem
Existing systems for machining the ends of rod-shaped or tubular workpieces suffer from inadequate processing accuracy and slow processing speeds, particularly during continuous machining of multiple workpieces.
Innovation Solution
A system comprising a conveyor device and two machining devices, each with a clamping, sawing, and chamfering unit, where the machining devices are aligned with common axes and movable relative to a common support, allowing simultaneous machining of both ends of a workpiece without re-clamping, and the clamping devices ensure precise positioning using a V-shaped holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the workpiece is clamped, cut, and machined in separate operations with re-clamping, then the machining process is simple, but the manufacturing precision decreases and processing time increases
Solution Approach 1:
The patent combines the cutting device and machining device into a single integrated processing unit that performs both operations on the workpiece without release or re-clamping. The cutting tool and machining tool are arranged on the same processing device, allowing sequential operations on the workpiece end face while maintaining continuous clamping, thereby preserving manufacturing precision and simplifying the overall process.
Solution Approach 2:
The workpiece is clamped in advance by the clamping device before any processing begins. This preliminary clamping action is maintained throughout both the cutting and machining operations, ensuring the workpiece remains securely positioned and serves as a reference for subsequent operations, thus maintaining high manufacturing precision without requiring re-clamping.
2Productivity
If the workpiece is clamped and released between processing steps, then the device operation is simple, but the processing speed decreases and manufacturing precision is compromised
Solution Approach 1:
The clamping device maintains continuous clamping of the workpiece throughout the entire processing sequence, from initial positioning through cutting to final machining operations. This continuous useful action eliminates the need for releasing and re-clamping the workpiece, thereby maintaining both high processing speed and manufacturing precision without interruption or loss of positioning accuracy.
3Manufacturing precision
If multiple measuring and adjusting operations are performed, then the positioning is precise, but the cycle time increases
Solution Approach 1:
The clamped workpiece serves as its own reference and positioning element throughout the processing operations. The clamping device and processing devices are configured so that the workpiece's own geometry and position, established during initial clamping, are used as the reference for cutting and machining operations, eliminating the need for separate measuring and adjusting operations and thus reducing cycle time while maintaining positioning accuracy.
