Solution Overview
Problem
Existing grinding machines are inefficient and laborious when grinding tools with cutting edges inclined at specific angles, as they rely on manual adjustment, which can be inaccurate and time-consuming, limiting their ability to adjust to different angles and resulting in uneven grinding.
Innovation Solution
A compact vertical grinding machine with adjustable support units that can be inclined to match the angle of the tool's cutting edge, using a system of adjustment elements and drive means to precisely position the abrasive wheel relative to the tool, allowing for quick and accurate adjustment of the support unit and controlled grinding operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment of the rotary table inclination is used, then the machine structure remains simple, but the inclination accuracy deteriorates and operator expertise is required
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated electro-hydraulic system. A programmable controller automatically controls the inclination of the rotary table and the position of the abrasive wheel through electronic signals, eliminating the need for manual operation while achieving precise and repeatable positioning without requiring operator expertise.
Solution Approach 2:
The system performs self-adjustment through automated programming. The controller automatically calculates and executes the required inclination angles and wheel positions based on pre-programmed parameters, allowing the machine to service itself without human intervention during the grinding setup process.
2Device complexity
If manual adjustment of the rotary table inclination is used, then the device complexity remains low, but the grinding time increases due to laborious adjustment operations
Solution Approach 1:
The patent replaces manual mechanical adjustment operations with automated electro-hydraulic actuation. The programmable controller rapidly positions the rotary table at the required inclination and adjusts the abrasive wheel position automatically, eliminating the time-consuming manual operations while keeping the overall device structure relatively simple through integrated control.
Solution Approach 2:
The system performs preliminary programming of the grinding parameters and inclination angles before the actual grinding operation. This allows the machine to be pre-configured for different tool types, and once programmed, the adjustments are executed automatically without requiring time-consuming manual reconfiguration for each grinding task.
3Productivity
If the abrasive wheel applies high force to the cutting edge, then the grinding effectiveness increases, but the abrasive means wear out faster
Solution Approach 1:
The patent incorporates feedback control through the programmable controller that monitors the grinding process parameters. The controller automatically adjusts the abrasive wheel position and feed rate based on real-time conditions, maintaining optimal contact force between the wheel and cutting edge. This ensures consistent grinding effectiveness while preventing excessive force that would accelerate abrasive wear.
Solution Approach 2:
The system dynamically adjusts the abrasive wheel position and feed rate during the grinding operation. Rather than applying constant high force, the electro-hydraulic system continuously optimizes the contact pressure based on the specific geometry of the cutting edge and the progress of the grinding operation, maintaining effectiveness while extending abrasive wheel life.
