Detachable Chipping Tool Head With Rotary Damping Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools face inadequate damping against impact loads during machining due to compression of damping elements under axial locking, leading to reduced effectiveness in absorbing sudden loads.
Innovation Solution
A cutting tool design featuring a reversibly detachable tool head with a locking device that maintains axial position and allows relative rotation, decoupling damping from axial position, and incorporating a damping element that can be adjusted for optimal damping performance, along with a main rotary bearing unit and driver elements for robust rotation transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the tool head is axially locked to the drive element, then the axial position is fixed and stable, but the damping element is compressed and becomes harder, reducing its damping effectiveness
Solution Approach 1:
The locking device is segmented into components that independently perform axial locking and rotational coupling functions. The drive element is separated from the tool head by the damping element, allowing axial positioning without compression of the damping material, thus maintaining both stability and damping effectiveness.
Solution Approach 2:
The damping element acts as an intermediary between the drive element and the tool head, allowing relative movement while transmitting torque. This intermediary arrangement enables axial locking without direct compression of the damping element, preserving its shock-absorbing properties.
2Reliability
If the damping element is made softer to improve damping, then damping effectiveness increases, but the structural strength and load-bearing capacity decrease
Solution Approach 1:
The damping element is constructed from composite materials that combine soft, damping-effective materials with reinforcing structures. This composite approach allows the element to remain soft for effective damping while maintaining sufficient structural strength to bear operational loads.
Solution Approach 2:
Different regions of the damping element have different material properties - the contact surfaces may be softer for damping, while internal structures or reinforcement elements provide the necessary strength. This local differentiation allows simultaneous optimization of both damping effectiveness and structural strength.
