Stacked Disk Tool Magazine for Fast Tool Change and Higher Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine tool tool magazines are not standardized, leading to high development and production costs and limited tool capacity, particularly in disk-type magazines, which require more time and space for tool changes.
Innovation Solution
A modularized disk-type tool magazine module with a ring-shaped magazine base and rotary shaft system that allows for vertical tool loading, enabling efficient rotation and increased tool capacity by stacking multiple bases, with a transfer system for easy tool exchange and oil collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a disk-type tool magazine is used, then the time required to exchange tools is short, but the number of tools capable of being loaded is limited
Solution Approach 1:
The patent transitions from a two-dimensional single disk magazine to a three-dimensional stacked configuration with multiple disk magazines arranged vertically. This dimensional change allows the system to maintain the fast exchange capability of individual disk magazines while significantly increasing the total tool capacity through vertical stacking, thereby resolving the contradiction between quick tool exchange and high tool storage capacity.
2Quantity of substance
If a chain-type tool magazine is used, then an increased number of tools can be accommodated, but more time and installation space are required for changing tools
Solution Approach 1:
The patent divides the tool magazine system into multiple independent disk magazine units that can operate separately. Each disk magazine maintains the fast exchange capability of the original design, while the segmented modular structure allows for increased total tool capacity through vertical stacking, avoiding the slow exchange times associated with chain-type magazines.
3Ease of manufacture
If a standardized automatic tool-change system is applied, then cost and effort for design and manufacture are reduced, but the system must accommodate various mounting positions and machine tool structures
Solution Approach 1:
The patent designs the disk magazine with a universal mounting structure that can accommodate various mounting positions (upper part of main shaft, upper part or side part of column) and different machine tool configurations. The standardized interface and modular design enable the same magazine unit to be adapted to different locations and machine types, achieving both cost reduction through standardization and flexibility through universal mounting capability.

AI summary
A tool magazine module of the machine tool is disclosed. The tool magazine module includes: a rotary shaft rotating by being connected to a drive part providing a rotational force; a plurality of magazine bases having a disk shape and being provided with a central part connected to a rotary shaft to be rotated, the plurality of magazine bases loaded with a tool along a rim thereof, and mounted by being stacked on the rotary shaft; and a transfer system enabling the tools to be interchanged between any magazine base and a tool changer by moving in an up-and-down direction and a forward-and-backward direction on one side of the magazine base.
