Tooling Exchange Mechanism That Reduces Turret Bending Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool exchange mechanisms in machine tools apply excessive bending moments and loads to the turret, reducing its durability.
Innovation Solution
A tooling exchange mechanism with a turret support and tooling detachment unit that includes a pressing member and a locking lever, where the pressing member presses the rear end of the tooling holding unit while the locking lever engages with an engaging projection, canceling the bending moment and reducing the load on the turret.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pressing member presses the rear side of the tool spindle unit to detach the tool, then the tool can be exchanged, but an excessive bending moment is applied to the unit holding portion of the turret and an excessive load is applied to the turret
Solution Approach 1:
The patent introduces a locking lever as an intermediary component between the pressing member and the tool spindle unit. The locking lever engages with an engaging projection on the tool holder, creating a lever arm that transforms the pressing force into a more favorable force distribution. This intermediary mechanism allows tool detachment while reducing the direct bending moment transmitted to the turret, thereby resolving the contradiction between tool exchange capability and turret durability
Solution Approach 2:
Instead of directly pressing the tool spindle unit from the rear as in conventional mechanisms, this patent inverts the approach by having the locking lever engage with the engaging projection first, then use the lever action to facilitate tool release. This inverted mechanism changes the force application point and direction, reducing the harmful bending moment on the turret while maintaining effective tool exchange functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism effectively reduces the bending moment and load on the turret during tool exchange by engaging the locking lever with the engaging projection, ensuring stable tool exchange without excessive stress on the turret.
Implementation Method 1
the tooling detachment unit includes an elastic member for biasing the tooling detachment unit itself toward the turret
