Threaded Weld Fixture Adjustment for Fast Tool Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixtures used with projection welders are time-consuming to adjust for different tools and changes to the welder, leading to reduced manufacturing efficiency and potential errors in welding.
Innovation Solution
A fixture with a housing and a shaft featuring external threads, an adjustment dial threaded onto the shaft, and a knob for clamping the tool, allowing for easy adjustment of the tool's position relative to the fixture and welder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fixtures are used with projection welders, then the workpiece can be held in position, but the fixture requires time-consuming adjustments when switching between different tools or after welder maintenance
Solution Approach 1:
The fixture incorporates a height adjustment mechanism with a threaded rod and adjustment dial that allows the operator to dynamically change the height of the anvil relative to the projection welder tip. This dynamic adjustment capability enables quick adaptation when switching between different tools or after welder maintenance without requiring time-consuming manual repositioning
Solution Approach 2:
The invention changes the parameter of fixture height through the threaded adjustment mechanism. By rotating the adjustment dial, the anvil height can be precisely modified to account for material removed from the welder tip or when using different tools, transforming a static fixture into one with adjustable parameters that adapts to varying manufacturing conditions
2Reliability
If adjustments are made to account for material removed from the welder tip, then welding effectiveness is maintained, but the adjustment process is time-consuming and reduces manufacturing efficiency
Solution Approach 1:
The height adjustment mechanism provides a dynamic solution for maintaining proper weld quality. When material is removed from the welder tip during maintenance, the operator can quickly adjust the anvil height using the threaded rod and dial mechanism, restoring the correct gap between the tip and workpiece without lengthy manual adjustments
Solution Approach 2:
The fixture enables self-adjustment capability through the integrated height adjustment mechanism. The operator can independently modify the anvil height to compensate for welder tip wear or maintenance activities, eliminating the need for external assistance or complex recalibration procedures
