Multi-Spindle Milling Motor Independent Drive Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-profile milling devices face challenges in flexibility and efficiency due to the need for complex adjustments and expert replacement of tools, leading to unnecessary material consumption and high wear during profile changes.
Innovation Solution
The introduction of an additional drive spindle between the movement device and the tool increases flexibility by allowing independent movement and rotation of milling tools, enabling easier profile changes and reducing wear through electro-pneumatic, electro-hydraulic, or electromagnetic control, with tools arranged coaxially to maintain efficient processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple profiles are formed on a single milling head arranged one above the other, then the multi-profile milling capability is achieved, but the adjustment complexity and material consumption increase when changing profiles
Solution Approach 1:
The milling device is divided into multiple independent milling heads, each with its own drive spindle. This segmentation allows each milling head to be independently controlled and positioned, eliminating the need for complex adjustments of a single multi-profile head and enabling easier profile changes.
Solution Approach 2:
Each milling head is equipped with an independent drive spindle that can be dynamically controlled. The drive spindles can be independently activated or deactivated based on the required profile, allowing dynamic adaptation without physical reconfiguration or complex adjustments.
2Ease of manufacture
If the entire milling tool is designed in one piece, then the structure is simple, but the cutting edges cannot be replaced individually leading to unnecessary material consumption
Solution Approach 1:
The milling tool system is segmented into multiple independent milling heads, each with its own drive spindle and cutting edges. This allows individual milling heads to be replaced or serviced independently, enabling selective replacement of only the worn cutting edges rather than the entire tool assembly.
Solution Approach 2:
The design enables selective replacement of only the worn milling heads or cutting edges while retaining functional ones. This discards only the necessary components (worn cutting edges) and recovers/reuses the still-functional cutting edges on other milling heads, reducing overall material consumption.
3Ease of operation
If the second tool is connected directly to the sliding cylinder on a ball bearing, then the tool can be moved axially, but the tool requires complex shrink fit attachment and expert personnel for replacement
Solution Approach 1:
A second drive spindle is introduced as an intermediary element between the sliding cylinder and the second milling head. This intermediary component simplifies the connection by providing a standardized interface, eliminating the need for complex shrink fit attachments and enabling easier tool replacement by regular personnel.

AI summary
Multi-profile milling device with several spindles (1, 2, 3), wherein a first tool (W1) is in the working position and a second tool (W2) can be brought into the working position. An additional spindle is provided between a sliding cylinder for the second tool (W2) and the tool itself. When the second tool (W2) is in the working position, its machining profile overlaps the machining profile of the first tool (W1) so that the workpiece being machined receives the second machining profile. Furthermore, the individual tools can be easily exchanged one at a time.
