Laser Welding Jig for Gap-Free Refrigerant Pipe Port Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerant pipe and charging port bonding processes often result in bonding defects due to production tolerances, leading to minute gaps and subsequent bonding defects between the refrigerant pipe and the charging port.
Innovation Solution
A jig device for laser welding featuring a semi-oval shaped seating groove and pressing blocks with semi-oval grooves to ensure close contact and accurate alignment between the refrigerant pipe and the charging port's fixing part, facilitating laser welding without gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional welding methods are used to bond the charging port to the refrigerant pipe, then the bonding process can be completed, but bonding defects occur due to minute gaps caused by production tolerances
Solution Approach 1:
The jig device acts as an intermediary tool that mediates between the charging port and refrigerant pipe during bonding. It provides a seating groove and pressing blocks that temporarily hold and align the components, eliminating gaps caused by production tolerances and enabling defect-free bonding.
Solution Approach 2:
The jig device performs preliminary alignment and positioning actions before the actual bonding process. The seating groove pre-positions the refrigerant pipe, and the pressing blocks pre-align the charging port, ensuring gap-free contact before welding or bonding begins.
2Reliability
If production tolerances are reduced to eliminate gaps, then bonding quality improves, but manufacturing complexity and cost increase
Solution Approach 1:
Rather than modifying the production process to reduce tolerances, the jig device serves as an intermediary that compensates for existing tolerances. It provides mechanical alignment and gap elimination during assembly, maintaining bonding quality without requiring complex manufacturing processes.
Solution Approach 2:
The jig device changes the physical parameters of the assembly process by providing fixed geometric references (seating groove shape, pressing block positions) that constrain the components to specific positions, effectively transforming variable tolerance conditions into fixed alignment conditions.
