Wheel Grinder with Movable Adjustment and Dust Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wheel grinders are unable to accurately grind arcuate workpieces due to fixed operation and work table configurations, leading to working errors.
Innovation Solution
A wheel grinder design featuring a movable adjustment portion with a vertical limitation frame, screw rods, and a stop cover with a defining plate to collect grinding dusts, allowing for precise adjustment and dust management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed operation portion and fixed work table are used, then the device structure is simple, but the device cannot accurately grind arcuate workpieces due to working errors
Solution Approach 1:
The operation portion is transformed from a fixed structure to a movable one, allowing it to tilt and adjust vertically. The mountings can rotate relative to the vertical limitation frame, enabling the grinding wheel to follow arcuate paths on workpieces, thereby achieving accurate grinding of curved surfaces while maintaining relatively simple device structure
Solution Approach 2:
The device is divided into separable components: the vertical limitation frame, the mountings, and the operation portion. This segmentation allows independent adjustment of each component, particularly the ability to tilt the operation portion relative to the work table, enabling accurate grinding of arcuate workpieces without requiring complete structural redesign
2Object-affected harmful factors
If grinding dusts are not collected, then the device structure is simple, but grinding dusts cause harmful environmental conditions and health issues
Solution Approach 1:
A stop cover with a defining plate is introduced as an intermediary component between the grinding area and the environment. The defining plate collects grinding dusts generated during operation and channels them through a designated opening, effectively controlling dust dispersion without requiring complex dust collection systems
Solution Approach 2:
The stop cover is designed as a separable component that can be removed from the main device body. This allows the dust collection function to be added to the device without permanently increasing its structural complexity, and enables easy maintenance and cleaning of the dust collection area

AI summary
A wheel grinder contains: a body, a work table, a vertical limitation frame, a movable adjustment portion configured to move vertically, a grinding wheel portion extending outward from the movable adjustment portion, and a motor fixed on the movable adjustment portion. The vertical limitation frame has two fixing holders, two mountings, and two first screw rods and two second screw rods which are inserted through the two mountings respectively and abut against a bottom of the movable adjustment portion. In addition, a stop cover is covered on the grinding wheel portion and includes a defining plate configured to define a connection shaft and an opening inside the defining plate.
