Cutting Tool Locking Mechanism for Blade Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary cutting tools face challenges in efficiently securing and orienting blades relative to teeth, leading to suboptimal cutting performance and frequent blade wear, requiring complex sharpening and alignment procedures.
Innovation Solution
A cutting tool design featuring a locking mechanism that secures a blade with adjustable orientation relative to teeth, allowing for easy blade replacement and maintenance without compromising cutting efficiency, utilizing a feed shaft and locking member to ensure precise alignment and secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is used to secure the blade to the body, then the blade is firmly held in position, but the mechanism for securing and orienting the blade becomes more complex
Solution Approach 1:
The locking mechanism is divided into separate functional components: a locking member that engages with the blade, an actuator that moves the locking member between locked and unlocked positions, and a feed shaft that controls blade positioning. This segmentation allows each component to perform its specific function efficiently while simplifying the overall design and maintenance of the system.
2Manufacturing precision
If the blade orientation is fixed relative to the teeth, then the cutting performance is optimized, but the blade cannot be easily replaced or adjusted
Solution Approach 1:
The blade positioning system transitions from a fixed orientation to a dynamic, adjustable orientation. The feed shaft and locking mechanism allow the blade to be positioned at different orientations relative to the teeth during operation, and can be quickly removed and replaced by actuating the locking mechanism. This dynamic capability maintains precise alignment when needed while enabling easy blade replacement.
3Stability of the object's composition
If the blade is securely locked in place, then cutting stability is improved, but blade maintenance and replacement require more time and effort
Solution Approach 1:
The locking mechanism is designed so that the locking member is pre-positioned and ready to engage with the blade. When blade replacement is needed, the actuator quickly moves the locking member to the unlocked position, allowing rapid blade removal. The feed shaft is also pre-configured to automatically position the new blade in the correct orientation upon insertion, eliminating the need for manual alignment and reducing replacement time.

AI summary
A cutting tool including a body, a blade, a feed shaft, and a locking member. The body defines an axis and is adapted to be received by a spindle of a power tool. The blade is removably supportable on the body and rotatable about the axis for cutting a workpiece. A feed shaft is removably supportable in the body and rotatable about the axis for engaging a workpiece, the feed shaft being mountable in the cutting tool to engage and at least partially restrain the blade. The feed shaft further includes an opening transverse to the axis. The locking member is engageable with the body and with the opening in the feed shaft. Advancement of the locking member into the opening tightens both the blade and the feed shaft to the body.
