Sloped Ball Magazine Structure for Sequence-Stable Lapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ball magazines for lapping and grinding machines fail to maintain the sequence of balls being processed, leading to unequal processing and potential blockages due to mixing and sticking of balls with lapping/grinding agents.
Innovation Solution
A ball magazine design with a storage section having a gradient to maintain ball sequence, a raising unit to elevate balls back to processing level, and guiding elements to prevent sticking and mixing, ensuring controlled ball flow through channels adapted to ball diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a drum-type magazine or bucket elevator is used to store and feed balls, then the balls can be collected and fed back to the lapping discs, but the balls become mixed together in an uncontrollable manner, leading to unequal processing
Solution Approach 1:
The storage section is divided into multiple compartments separated by partition walls. Each compartment holds a specific number of balls, preventing mixing between different groups of balls. This segmentation maintains the sequence of balls while still allowing multiple balls to be stored and fed back systematically.
2Stability of the object's composition
If a ring magazine is used to maintain ball sequence, then balls can be fed back in the same sequence, but the balls can become stuck in the ring magazine due to entrained lapping and grinding agents, causing blockages
Solution Approach 1:
The bottom of the storage section is designed with a gradient that slopes downward toward the ball feed section. This dynamic gradient structure uses gravity to continuously move balls forward, preventing them from becoming stuck. The gradient ensures that even with lapping and grinding agents present, balls maintain movement and do not block the magazine.
3Device complexity
If balls are processed in a common reserve without separation, then the magazine structure is simple, but only balls of large diameter are actually lapped while others are carried along without being processed
Solution Approach 1:
The storage section is divided into multiple compartments with partition walls, creating separate storage areas for different groups of balls. This segmentation allows for more controlled ball feeding, ensuring that balls are processed in an orderly sequence rather than being mixed together, thereby improving diameter uniformity while maintaining reasonable structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Maintains ball sequence and reduces the risk of blockages by ensuring consistent processing and smooth ball flow, enhancing the quality of the lapping/grinding process.
Implementation Method 1
the storage section at least partially has a gradient (is sloped). By means of the gradient, it can be achieved that the balls reach a speed sufficient to reduce the risk of them becoming stuck

AI summary
A ball magazine for a device for lapping and/or grinding balls includes a ball removal section configured to be connected to the device and receive balls from the device, a ball storage section connected to the ball removal section and configured to receive the balls from the ball removal section, and a ball feed section configured to guide the balls from the ball storage section back to the device. At least part of the ball storage section, which may be formed as a channel, is sloped.
