Refitting Mechanism for Workpiece Flatness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refitting mechanisms for workpieces are inefficient due to the need for repeated manual transfer and potential incorrect pressing, leading to reduced accuracy and increased time consumption in achieving qualified flatness.
Innovation Solution
A refitting mechanism comprising a positioning assembly, holding assembly, measuring unit, and controller that automatically positions, measures, and refits workpieces by aligning and pressing deformed portions based on flatness value comparisons, reducing human intervention and enhancing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual transfer and refitting is performed repeatedly, then the workpiece can be refitted, but time consumption increases significantly
Solution Approach 1:
The patent combines the measuring unit and refitting assembly into a single integrated system that can simultaneously measure flatness and perform refitting operations. The measuring unit measures the workpiece flatness while the refitting assembly is positioned on the worktable, eliminating the need for separate manual transfer operations between measurement and refitting stations.
Solution Approach 2:
The worktable serves multiple functions: it supports the workpiece during measurement, positions the refitting assembly for correction operations, and maintains the workpiece in a consistent position throughout the process. This multi-functional design eliminates the need for separate fixtures and transfer operations.
2Manufacturing precision
If manual transfer is performed multiple times, then refitting can be repeated, but refitting accuracy decreases due to incorrect pressing
Solution Approach 1:
The measuring unit provides real-time feedback on workpiece flatness to the control system. The controller uses this feedback information to automatically adjust the refitting assembly's pressing force and position, ensuring accurate refitting without manual intervention. This closed-loop control prevents incorrect pressing that would occur with manual operations.
Solution Approach 2:
The system performs self-positioning and self-correction through automated control. The controller automatically positions the refitting assembly based on measurement data and executes precise pressing operations without requiring manual repositioning or judgment, eliminating errors from incorrect manual pressing.
3Productivity
If automated refitting is implemented, then time consumption is reduced, but device complexity increases
Solution Approach 1:
The worktable is designed as a multi-functional platform that simultaneously supports measurement, positioning, and refitting operations. This universal design consolidates multiple separate devices into one integrated system, achieving automation without proportionally increasing overall system complexity.
Solution Approach 2:
The controller serves as an intermediary that coordinates between the measuring unit and refitting assembly. It processes measurement data and automatically controls the refitting operations, simplifying the automation process by using a centralized control system rather than complex direct mechanical linkages.

AI summary
A refitting mechanism for measuring a flatness value of a workpiece and refitting the workpiece includes a worktable, a refitting assembly, a measuring unit, and a controller. The refitting assembly is movably assembled to the worktable. The holding assembly is assembled to the worktable and adjacent to the refitting assembly for holding the workpiece on the worktable. The measuring unit is assembled to the refitting assembly. The controller is electrically connected to the refitting assembly, the holding assembly, and the measuring unit. The measuring unit measures a flatness value of the workpiece and transfers the flatness value to the controller. The controller compares the flatness value with a preset value range to determine whether the workpiece is qualified or not. When the workpiece is not qualified, the controller controls the holding assembly to hold the workpiece, and controls the refitting assembly to refit the workpiece.
