Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding fixtures for box-type parts suffer from low positioning accuracy, affecting welding seam width and quality, and are unable to effectively hold parts with different specifications due to their inability to adapt to varying shapes.
Innovation Solution
A welding fixture incorporating a two-dimensional moving apparatus with multiple lifting apparatuses, each equipped with specific electromagnets, allows for precise positioning and holding of box-type parts with different specifications through a three-dimensional moving adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cylinders are used to position the box-type parts in the welding fixture, then the structure is simple, but the positioning accuracy is low which affects welding seam width and quality
Solution Approach 1:
The patent replaces the traditional mechanical cylinder positioning system with an electromagnet-based positioning system. The electromagnets can precisely control the position of box-type parts through magnetic attraction, achieving high positioning accuracy for the welding seams while maintaining reasonable structural complexity through modular design.
Solution Approach 2:
The patent changes the positioning parameter from mechanical contact (cylinders) to magnetic field interaction (electromagnets). This parameter change enables continuous and precise adjustment of positioning force and position, directly improving positioning accuracy for welding seam width control.
2Adaptability or versatility
If traditional welding fixtures are used, then the device complexity is low, but they cannot effectively hold and position box-type parts with different specifications
Solution Approach 1:
The patent designs the welding fixture with multiple electromagnets that can be independently controlled to adapt to different box-type part specifications. The same fixture structure can hold and position various sizes and shapes of box-type parts by adjusting the electromagnet activation patterns, achieving universality without requiring multiple dedicated fixtures.
Solution Approach 2:
The patent introduces dynamic control of electromagnets, where the activation and positioning of individual electromagnets can be adjusted in real-time based on the specific dimensions and shape of the box-type parts being welded. This dynamic adaptability allows a single fixture to handle multiple part specifications effectively.
