Master Link Wire-Cutting Reference Hole Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional master link manufacturing methods result in low process speed and increased cutting errors, reducing the precision and quality of the product due to reliance on wire-cutting alone for dividing the master link into partial link units.
Innovation Solution
A method involving the formation of a wire-cutting reference hole, followed by wire-cutting based on this hole to create precise contours, which reduces cutting errors and enhances precision by separating the master link into first and second partial link units with defined assembly portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If wire-cutting is used to divide the master link into partial link units, then the master link can be separated into assembly portions, but the process speed is low and cutting error is increased
Solution Approach 1:
A wire-cutting reference hole is formed at a predetermined position between the partial link units before the actual wire-cutting operation. This preliminary action establishes a precise reference point that guides subsequent cutting operations, ensuring high precision without sacrificing process speed
Solution Approach 2:
The wire-cutting reference hole acts as an intermediary element that facilitates precise wire-cutting operations. By inserting the wire through this pre-formed reference hole, the cutting process achieves higher precision while maintaining efficient process speed
2Manufacturing precision
If wire-cutting is used to form assembly portions, then the partial link units can be created, but cutting error is increased thus reducing product quality
Solution Approach 1:
The wire-cutting reference hole is formed in advance at a predetermined position, establishing a precise reference point before the actual cutting of assembly portions occurs. This preliminary positioning action eliminates cutting errors by providing an accurate starting point for wire insertion
Solution Approach 2:
The reference hole serves as an intermediary that transfers precise positioning information to the cutting operation. By guiding the wire through this pre-formed hole, the system achieves high measurement precision and eliminates cutting errors in forming assembly portions

AI summary
Disclosed herein is a method of manufacturing a master link which connects ends of track chains of an endless track to each other. More particularly, the present invention relates to a method of manufacturing a master link which includes a pair of partial link units that are separably coupled to each other, and which can markedly enhance the degree of precision in machining the partial link units and the quality of the product. The method includes forming a wire-cutting reference hole at a predetermined position in the master link so that a wire is inserted into the wire-cutting reference hole, and forming the first and second partial link units by wire-cutting after inserting the wire into the wire-cutting reference hole.
