Deburring Tool Bracket Structure for Low-Load Spindle Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring tools face difficulty in tilting the spindle body due to moment loads, making it challenging to reduce the required load for tilting.
Innovation Solution
A tool bracket and deburring tool design that includes a piston urged by compressible fluid, a tilting body with a centering portion, and a spindle body that tilts integrally with the tilting body, allowing the spindle body to tilt even with small moment loads by using the cylinder axis as an action line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional piston structure is used in the deburring tool, then the structure is simple, but the spindle body cannot be tilted when moment load is small
Solution Approach 1:
The piston structure is segmented into a piston body and a separate centering portion that can tilt relative to the piston body. This segmentation allows the centering portion to tilt when moment load is small while the piston body remains stable, resolving the contradiction between tilting capability and structural simplicity.
Solution Approach 2:
The centering portion is designed to dynamically tilt relative to the piston body based on the moment load conditions. When moment load is small, the centering portion tilts to enable spindle body tilting; when moment load is large, it returns to a centered position. This dynamic behavior enables tilting capability without requiring a completely complex structural system.
2Ease of operation
If the piston is pressed against by the tilting body with cylinder axis as action line, then smooth tilting is achieved, but the piston structure becomes more complex
Solution Approach 1:
The piston is divided into a piston body and a centering portion that can tilt independently. The centering portion includes a tilting surface that contacts the workpiece, allowing it to tilt while the piston body remains stable. This segmentation enables smooth tilting without requiring complex overall piston restructuring.
Solution Approach 2:
The centering portion acts as an intermediary between the piston body and the workpiece. It transfers the tilting motion from the spindle body to the workpiece contact point, enabling smooth tilting while protecting the main piston structure from excessive complexity.

AI summary
Provided is a tool bracket capable of tilting a spindle body even when a moment load acting on the spindle body is relatively small. A tool bracket includes: a housing including a cylinder chamber extending along a cylinder axis; a piston urged by compressible fluid toward distal end to reciprocate in the cylinder chamber and having an action portion disposed at distal end; and a tilting body having a tilt axis and disposed in the cylinder chamber in a tiltable manner with respect to the cylinder axis, and includes a centering portion disposed at basal end to abut the action portion, the centering portion presses the piston with the cylinder axis as an action line when the tilt axis is tilted from the cylinder axis.
