Horizontal Wheelhead Deburring Machine Double-Action Grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring machines with annular grinding belts have low grinding efficiency as the wheelhead can only be arranged vertically, allowing the workpiece to be ground only once, resulting in inefficient deburring and leaving blind angles.
Innovation Solution
The deburring-machine abrasive belt features wheelheads connected horizontally to the annular base belt, allowing the grinding belt to deburr and polish surfaces forward and backward twice per revolution, with adjustable grinding distance and pressure, and conical drum surfaces for precise contact and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wheelhead is mounted vertically on the front of the annular grinding belt, then the structure is simple, but the workpiece can only be ground once with low grinding efficiency
Solution Approach 1:
The wheelhead is mounted horizontally on the side of the annular grinding belt rather than vertically on the front, changing the spatial arrangement from one-dimensional vertical mounting to two-dimensional side mounting. This allows the workpiece to pass through and be ground twice per belt rotation, doubling the grinding efficiency while maintaining structural simplicity through the horizontal connection design.
2Manufacturing precision
If the wheelhead is fixed vertically on the grinding belt, then the structure is stable, but blind angles remain and deburring is incomplete
Solution Approach 1:
By mounting the wheelhead horizontally on the side of the belt rather than vertically on the front, the grinding action occurs from the side, allowing the workpiece to be ground twice per rotation and eliminating blind angles that would remain with vertical front mounting.
Solution Approach 2:
Instead of having the wheelhead grind the workpiece from the front in a single pass, the horizontal side mounting causes the workpiece to pass through the grinding zone twice during one belt rotation, effectively inverting the single-pass limitation into a double-pass advantage.
3Productivity
If the grinding belt is driven only annularly, then the drive mechanism is simple, but the wheelhead cannot deburr up or down with high efficiency
Solution Approach 1:
The drive mechanism is enhanced from simple annular driving to include lateral driving capability, making the grinding belt dynamically capable of both annular and lateral motion. This allows the horizontally mounted wheelhead to deburr up or down with high efficiency while maintaining relatively simple drive mechanics through the lateral connection design.

This design significantly improves deburring efficiency by 100%, allows for deburring of workpieces of different thicknesses, and eliminates blind angles, while enabling automatic elastic contact and separation of abrasive blocks, resulting in high-quality and efficient deburring.
Implementation Method 1
multiple abrasive blocks (5) are planted on the grinding belt (7)... the abrasive block can deburr and polish each surface of the workpiece
