Multi-Rotor Grinding Machine for Axially Symmetric Bodies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for grinding pump rotor surfaces require long working times and high production costs due to sequential processing of radial slits, which limits efficiency and increases costs.
Innovation Solution
A machine tool with multiple rotary tools positioned around a feed trajectory allows simultaneous grinding of axially symmetrical metal bodies, utilizing a circular arrangement of disk-shaped tools that rotate orthogonally to the feed path, enabling multiple surface processing in a single operation and reducing processing time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequential grinding of radial slits is used, then manufacturing precision is maintained, but productivity is reduced and processing time increases
Solution Approach 1:
The invention divides the single grinding wheel into multiple disk grinding wheels (at least two) arranged radially around the rotor pack. Each disk grinding wheel is assigned to grind specific radial slits simultaneously, transforming a sequential single-wheel process into a parallel multi-wheel process that increases productivity while maintaining precision through dedicated grinding zones
Solution Approach 2:
The invention combines multiple grinding operations into a single coordinated process by arranging multiple disk grinding wheels in radial positions around the rotor pack. All disk grinding wheels operate simultaneously on different radial slits of the same rotor or adjacent rotors, merging what were previously separate sequential operations into one concurrent processing step
2Manufacturing precision
If sequential grinding of all slots is performed, then complete surface coverage is achieved, but production costs increase proportionally
Solution Approach 1:
The grinding system is segmented into multiple independent disk grinding wheels, each responsible for specific radial slits. This segmentation allows simultaneous processing of multiple surfaces while maintaining the quality standards of individual grinding operations, as each disk wheel can be optimized for its specific grinding zone
Solution Approach 2:
The rotor pack design with radially arranged slots allows the same structure to be processed by multiple disk grinding wheels simultaneously. The universal radial geometry enables concurrent grinding operations on different slots without requiring repositioning or reconfiguration, achieving complete surface coverage through parallel multi-functional processing
3Device complexity
If single disk grinding wheel is used, then device complexity is low, but processing time becomes excessively long
Solution Approach 1:
The invention transitions from a single grinding wheel operating in one position to multiple disk grinding wheels arranged in a radial dimension around the rotor pack. This spatial arrangement in multiple dimensions around the central axis enables simultaneous access to multiple radial slits, dramatically reducing processing time while the modular radial configuration keeps the added complexity manageable
