Integrated Cutting Apparatus for Polygonal Rod Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing machining processes for polygonal rods are inefficient due to time-consuming workpiece transfer between lathe and polygonal turning machines, affecting precision as both tools need to be repositioned relative to the workpiece.
Innovation Solution
A cutting apparatus integrated with a mounting frame, cutting unit, locking unit, driving unit, and control unit, allowing the same tool to function as both a lathe and a polygonal cutter, with a latch assembly and sensor system to control rotation and positioning, eliminating the need for repositioning during machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the workpiece is transferred from lathe to polygonal turning machine, then turning operation is completed, but time is lost and machining precision is affected
Solution Approach 1:
The patent combines the lathe tool and polygonal cutter into a single integrated cutting apparatus that can perform both turning operations and polygonal cutting operations sequentially on the same workpiece without requiring transfer between different machines. The cutting apparatus includes a rotating shaft with a cutter assembly that can be positioned to perform lathe cutting first, then polygonal cutting, eliminating the time-consuming transfer process between separate lathes and polygonal turning machines.
Solution Approach 2:
The cutting apparatus is designed with multi-functionality to serve as both a lathe tool and a polygonal cutter. The cutter assembly can be configured to perform different cutting functions by adjusting its position and orientation relative to the workpiece. This universal tool can complete both turning operations and polygonal forming operations in one setup, eliminating the need for separate specialized machines and improving overall productivity.
2Adaptability or versatility
If lathe tool and polygonal cutter are positioned relative to workpiece in turn, then both operations can be performed, but machining precision is affected
Solution Approach 1:
The patent merges the lathe tool and polygonal cutter into a single cutting apparatus with a unified positioning system. The cutting apparatus includes a mounting frame and rotating shaft assembly that provides consistent reference frames for both cutting operations. By performing both turning and polygonal cutting from the same positioned apparatus, the system eliminates cumulative positioning errors that would occur when transferring the workpiece between separate machines, thereby maintaining higher machining precision.
Solution Approach 2:
The cutting apparatus is pre-positioned and locked in place before performing either cutting operation. The positioning system establishes the workpiece orientation and apparatus position in advance, and this pre-established position is maintained throughout both the turning operation and subsequent polygonal cutting operation. This preliminary positioning action ensures that both cutting functions are performed from the same reference frame, eliminating the need for repositioning and preserving machining precision.
3Adaptability or versatility
If separate lathe and polygonal turning machines are used, then specialized operations can be performed, but device complexity increases
Solution Approach 1:
The patent implements a universal cutting apparatus that consolidates the functionality of separate lathe and polygonal turning machines into a single device. The apparatus includes a mounting frame, rotating shaft, and cutter assembly that can be configured to perform both turning operations and polygonal cutting operations. This multi-functional design reduces the overall number of machines required in the workshop, simplifies the production line configuration, and eliminates the complexity of coordinating multiple separate machines while maintaining the capability to perform specialized cutting operations.

AI summary
A cutting apparatus adapted for use in a machine tool. The cutting apparatus includes a mounting frame. A cutting unit is mounted rotatably in the mounting frame. A locking unit is connected to the mounting frame and the cutting unit, for restraining or permitting relative movement between the mounting frame and the cutting unit. A driving unit drives rotation of the cutting unit. A control unit controls the driving unit to drive rotation of the rotating shaft upon detecting that the relative movement between the mounting frame and the cutting unit is permitted. The control unit shuts off the driving unit upon detecting that the relative movement between the mounting frame and the cutting unit is restrained.
