Machine Tool Spindle Stacking Unit Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine tools face interference issues due to a fixedly attached stacking device, leading to reduced processing precision and productivity, and increased maintenance costs from contamination by chips and foreign substances.
Innovation Solution
A machine tool design where the stacking unit is detachably mounted on the spindle and its position changed by a storage unit based on the workpiece's processing position, minimizing interference and allowing for automatic positioning to prevent contamination during general processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the stacking device is fixedly attached to the spindle, then the stacking processing can be performed continuously, but interference occurs during processing and the stacking processing area is limited
Solution Approach 1:
The stacking device is designed to be movable relative to the spindle, allowing dynamic adjustment of its position. The device can be detached from the spindle and repositioned to different locations around the workpiece, enabling continuous stacking processing while avoiding interference with machining operations by adapting its position based on the current processing requirements
2Productivity
If the stacking device is fixedly mounted on the spindle, then the stacking processing can be performed, but the processing precision deteriorates due to interference
Solution Approach 1:
The stacking device can dynamically adjust its position relative to the spindle and workpiece. When stacking processing is not required or would cause interference, the device is detached and repositioned to a non-interfering location, thereby maintaining high machining precision while preserving the capability to perform stacking processing when needed
3Adaptability or versatility
If the stacking device is always mounted on the spindle, then stacking processing can be performed随时, but the device is contaminated by chips and foreign substances increasing maintenance costs
Solution Approach 1:
The stacking device is extracted from the spindle mounting and repositioned to a separate location that is not exposed to machining chips and foreign substances. This allows the stacking function to remain available while protecting the stacking device from contamination, thereby reducing maintenance costs and extending device life
4Device complexity
If a fixed stacking device position is used, then the structure is simple, but the stacking processing area is limited
Solution Approach 1:
The stacking device incorporates a movable mounting mechanism that allows it to be repositioned to different locations around the workpiece. This dynamic positioning capability expands the effective stacking processing area while maintaining relatively simple structural design through the use of standardized mounting interfaces and straightforward repositioning mechanisms
