Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring tools that can tilt are typically designed for use with rotating spindles, limiting their application to robots without such spindles.
Innovation Solution
A tool bracket system that allows a spindle body to be smoothly inserted and tilted, featuring a housing with a cylinder chamber, a tilting body with a tilt axis, and a rotation stopper member to prevent spindle rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a deburring tool is designed with a tilting mechanism for use with rotating spindles, then the tool can perform deburring operations, but it cannot be applied to robots without rotating spindles
Solution Approach 1:
The tool bracket is designed with a universal mounting interface that can accommodate both rotating spindles and robot flange mounts. The housing includes a mounting interface configured to be mounted to either a rotating spindle or a robot flange mount, enabling the same device to function in multiple contexts without requiring separate designs for different mounting systems.
2Ease of operation
If the spindle body is allowed to tilt freely, then the tool can adapt to different workpiece angles, but the spindle may rotate uncontrollably
Solution Approach 1:
A rotation stopper member is introduced as an intermediary component between the spindle body and the tilting mechanism. This stopper member engages with a receiving groove to prevent rotational movement of the spindle body while allowing the tilting mechanism to operate smoothly, thus mediating between the need for free tilting and the need for rotational stability.
Solution Approach 2:
The tilting mechanism is segmented into distinct functional components: a tilting body that enables angular adjustment, a rotation stopper member that prevents unwanted rotation, and a receiving groove that guides the tilting motion. This segmentation allows each component to perform its specific function independently, ensuring smooth tilting while maintaining rotational stability.
3Stability of the object's composition
If the spindle body is constrained to prevent rotation, then rotational stability is achieved, but the tilting mechanism may become stuck
Solution Approach 1:
The rotation stopper member acts as a selective constraint that prevents rotation only when engaged with the receiving groove in the constrained position. During tilting operations, the stopper member disengages from the groove, allowing smooth tilting motion. This intermediary mechanism provides rotational stability when needed without interfering with the tilting function.
Solution Approach 2:
The constraint system is designed to be dynamic rather than static. The rotation stopper member can engage with or disengage from the receiving groove depending on the operational state. During tilting, the mechanism allows the stopper to disengage, enabling smooth motion. During positioning, the stopper engages to provide rotational stability, creating a dynamic constraint system that adapts to operational needs.

Function Achieved in This Case
Enables the spindle body to be effectively tilted within the tool bracket, facilitating deburring operations on robots without rotating spindles by ensuring smooth tilting and stabilization of the spindle.
Implementation Method 1
a piston including an action portion disposed in a distal end portion, the piston configured to be urged toward a distal end by compressible fluid to reciprocate in the cylinder chamber
Implementation Method 2
the tilting body including a centering portion disposed in the cylinder chamber to abut against the action portion, the centering portion configured to press the piston with the cylinder axis as an action line when the tilt axis is tilted from the cylinder axis
