Rotary Processing Tool Synchronization via Offset Pivot Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating processing devices face challenges in maintaining synchronization of tool formations during extended positions, requiring secondary synchronization means to prevent disengagement of synchronization gears, which complicates the construction and operation.
Innovation Solution
The device allows one tool to be pivoted relative to another about a pivot axis without canceling the engagement of synchronization gears, using a pivot axis that is offset by 0.05 times or less the distance between the tool formations, ensuring synchronization is maintained even in the extended position without the need for secondary synchronization means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tools are moved apart for material insertion or tool replacement, then accessibility and maintenance are improved, but synchronization gear engagement is lost requiring secondary synchronization means
Solution Approach 1:
The pivot axis is positioned offset from the theoretical center of the engagement area, allowing the tools to dynamically pivot relative to each other during extended positions while the synchronization gears continuously roll on their teeth. This dynamic geometric relationship maintains gear engagement throughout the full range of motion, eliminating the need for secondary synchronization mechanisms.
2Manufacturing precision
If synchronization gears are used to maintain tool alignment, then manufacturing precision is improved, but device complexity increases due to additional synchronization mechanisms
Solution Approach 1:
The existing synchronization gears serve a dual function: they maintain precise circumferential orientation of tool formations during processing AND they continue to maintain synchronization during extended positions. The offset pivot axis design allows these gears to fulfill both roles simultaneously, eliminating the need for separate secondary synchronization means.
3Manufacturing precision
If tools are held in fixed circumferential orientation, then processing precision is improved, but adaptability for tool replacement and material insertion is reduced
Solution Approach 1:
The system transitions from a fixed geometric relationship to a dynamic one where the pivot axis is offset from the engagement area center. This allows tools to pivot during extended positions for maintenance and material insertion, then return to precise alignment during processing, combining adaptability with precision.

AI summary
The invention relates to a device (1) for rotating the machining of workpieces, with tools (4, 5) rotating about parallel tool axes (x, y) during machining, which preferably have several tool forms (10, 11) distributed over their respective circumferences, wherein the tools (4, 5) are held in a predetermined circumferential orientation relative to each other by means of synchronization gears (17, 18) rotating about the same tool axes (x, y) and engaging in a meshing area of tooth flanks, and the tools (4, 5) are movable apart for handling.To specify a device in which the synchronization of the tool features is ensured as simply as possible even in the separated position, it is proposed that one of the tools (4) be pivotable relative to the other tool (5) about a pivot axis (z) without disengaging the synchronization gears (17, 18) from each other, wherein the pivot axis (z) passes through the engagement area or is offset in the direction of the tool axis and/or perpendicular to it by 0.05 times or less of the distance (a) between a mean plane of a tool feature (10), optionally a mean plane of a tool feature (10) closest to the pivot axis (z), and the theoretical center of an engagement area.
