Cushioned Shield Holder for Damage-Free Workpiece Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining tools often damage workpieces when they are pushed out of the clamping device due to excessive force, causing them to hit hard surfaces within the tool.
Innovation Solution
A shield holder is designed to be detachably connected to the spindle of a machining tool, featuring a shield body with a cushion layer made of elastomer materials, which gently stops and cushions the workpiece as it is pushed out by the clamping device's pushing component, preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the pushing component pushes the workpiece out from the clamping device, then the workpiece can be ejected automatically, but the workpiece may be damaged due to excessive force
Solution Approach 1:
The patent introduces a shield holder as an intermediary component between the pushing component and the workpiece. The shield holder absorbs the excessive force from the pushing component and transmits a gentler force to the workpiece, preventing damage while maintaining automatic ejection functionality
Solution Approach 2:
The shield holder is positioned in advance to intercept the workpiece before it can be damaged by the pushing component. It provides cushioning protection beforehand, ensuring the workpiece is gently stopped even when pushed with excessive force
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shield holder effectively absorbs the impact force, preventing workpiece damage and allowing for automatic and safe ejection into a receiving box, enhancing the convenience and safety of the machining process.

AI summary
A shield holder is configured to be detachably connected to a spindle of a machining tool and has a connection portion configured to be detachably connected to the spindle and a shield portion formed at an end of the connection portion. The shield portion includes a shield body integrally formed with the connection portion and a cushion layer formed on and covering a surface of the shield body. After a workpiece is processed, the shield holder is substituted for a cutter holder and is connected to the spindle for blocking the workpiece pushed out from a clamping device to prevent the workpiece from damage.
