Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for deburring metal workpieces are ineffective in simultaneously removing burrs from multiple locations, leading to potential damage and injury risks during assembly.
Innovation Solution
A device utilizing a rotationally symmetric form cutter that is plunged into an intersecting opening and rotated to remove burrs from multiple boreholes simultaneously, featuring a parabolic centering bore and shearing edges for efficient and automated deburring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional deburring devices are used, then burrs can be removed from individual locations, but multiple burrs cannot be removed simultaneously
Solution Approach 1:
The form cutter is segmented into multiple cutting edges arranged radially around its circumference, allowing simultaneous contact with multiple boreholes. Each cutting edge can remove a burr from a different borehole during a single rotational operation, enabling parallel deburring of multiple locations.
Solution Approach 2:
Multiple deburring functions are merged into a single form cutter tool. The cutter combines multiple cutting edges and centering features in one integrated component that can handle multiple boreholes simultaneously, eliminating the need for multiple separate deburring operations or tools.
2Manufacturing precision
If a form cutter is plunged directly into boreholes, then burrs can be removed, but the cutter cannot be properly positioned or centered
Solution Approach 1:
The form cutter includes a centering portion with a parabolic profile that performs preliminary centering action before the cutting edges engage the boreholes. This centering portion is plunged into a parabolic centering bore first, which automatically positions and orients the cutter correctly, ensuring accurate alignment before deburring begins.
Solution Approach 2:
A parabolic centering bore acts as an intermediary feature between the workpiece and the form cutter. This centering bore receives and properly positions the form cutter's centering portion, serving as a mediator that ensures precise alignment and orientation of the cutter relative to multiple boreholes before the actual deburring operation.
3Productivity
If multiple boreholes are deburred individually, then each burr can be removed, but the process is time-consuming and reduces productivity
Solution Approach 1:
The form cutter rotates periodically during the deburring operation, with each rotation bringing different cutting edges into contact with different boreholes. This periodic rotational motion allows the cutter to systematically engage and remove burrs from multiple boreholes in sequence during a single continuous operation, significantly reducing total deburring time.
Solution Approach 2:
The deburring operation is performed continuously in a single plunging and rotating motion rather than through multiple separate operations. The form cutter maintains continuous contact with multiple boreholes during rotation, eliminating idle time between deburring individual holes and maximizing productive action throughout the entire operation.
