Dual-head Grinding Machine Partitioning Cover for Coolant Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grinding machines with two grinding heads face challenges in preventing coolant and coolant mist scattering, as existing cover structures are designed for single-head machines and struggle to synchronize with the varying distance between grinding heads, leading to coolant accumulation on bearing and drive mechanisms, causing operational issues.
Innovation Solution
A grinding machine design featuring a partitioning mechanism with fixed and extendable covers, including bellows covers, that seals the machining region between the grinding heads, preventing coolant and coolant mist from scattering by positioning the clamping and grinding components inside the machining area and the bearing and drive components outside, while allowing for movement synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the entire machine is covered by a cover to prevent scattering of coolant, then coolant scattering is prevented, but coolant accumulates on bearing portions and drive mechanisms causing operational troubles
Solution Approach 1:
The cover is divided into a movable cover portion that moves with the grinding head and a fixed cover portion, creating a segmented sealing system that isolates the machining region while leaving bearing and drive mechanism areas exposed
2Object-affected harmful factors
If a telescopic cover and bellows cover are used to seal the machining region, then coolant scattering is prevented, but the structure cannot adapt to distance changes between grinding heads
Solution Approach 1:
The movable cover portion is designed to move synchronously with the grinding head in the left-right direction, dynamically adapting the seal position to accommodate changes in the distance between grinding heads while maintaining effective coolant containment
3Ease of operation
If the grinding head moves forward and backward toward the workpiece, then machining is performed, but the cover structure becomes complex to maintain sealing
Solution Approach 1:
The movable cover portion moves synchronously with the grinding head's reciprocating motion, maintaining a consistent seal between the grinding head and workpiece area throughout the forward and backward movement cycle without requiring complex adjustment mechanisms

AI summary
A grinding machine includes a pair of workpiece support devices (12, 13), which clamp and rotate a workpiece (W), on a bed (11). A pair of saddles (14) is provided on the bed (11) in such a way as to be movable along the rotational axis of the workpiece (W). Grindstone heads (16) provided with rotating grindstones (16c) and drive mechanisms (16d) are supported on the saddles (14) in such a way as to be movable in a direction that perpendicularly intersects the movement direction of the saddles (14). There is provided a partition structure (20) which consists of a fixed cover (21) and a extendable cover (22), and serves to partition a machining region (T) for the purpose of sealing off the same so that the clamping portions (12a, 13a) and the rotating grindstones (16c) of both of the workpiece support devices (12, 13) will be located inside the machining region (T), and that bearing sections (12b, 13b) and driving sections (12c, 13c) of both of the workpiece support devices (12, 13), as well as bearing sections (16b) and driving sections (16d) of both of the grindstone heads (16), will be located outside the machining region (T).
