Weld Tip Removal Mechanism With Rotating Plate to Prevent Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weld tip removers are inefficient in removing weld tips from shanks without bending the shank or weld tip during the removal process.
Innovation Solution
A weld tip remover with a cylindrical tubular case featuring an inclined guide groove, a rotating plate with a tip receiving hole, and a hinge bar connected to a translational actuator, which allows for efficient removal of weld tips by rotating and moving the plate in a manner that prevents bending of the shank and weld tip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional weld tip remover is used, then the weld tip can be removed from the shank, but the shank and weld tip may be bent during the removal process
Solution Approach 1:
The rotating plate is designed to rotate dynamically during the weld tip removal process, allowing the driving jaw to engage and extract the weld tip while the rotating plate moves to accommodate the extraction trajectory. This dynamic motion prevents bending by adapting the removal path to the weld tip's position and orientation.
Solution Approach 2:
The inclined guide groove acts as an intermediary mechanism between the translational actuator and the rotating plate. It converts the linear motion of the actuator into rotational motion of the plate, providing a controlled and gradual engagement that prevents sudden forces causing bending during weld tip removal.
2Productivity
If the rotating plate rotates quickly to improve efficiency, then work efficiency increases, but the risk of bending the shank or weld tip increases
Solution Approach 1:
The removal process uses periodic action through the rotational movement of the plate combined with the translational motion of the actuator. The hinge bar mechanism creates a controlled periodic engagement and disengagement cycle, allowing the weld tip to be extracted in a series of controlled movements rather than a single rapid motion, thus preventing bending while maintaining efficiency.
