Finishing Machine Stone Turning Unit Coupled Rotary Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Finishing machines with stone turning units face increased mass and installation space requirements due to drive units, which also lead to higher drive power needs and complex guidance systems, especially when oscillating motions are involved during processing.
Innovation Solution
A finishing machine design where the stone turning unit is coupled to a controllable rotary drive of the workpiece holder, allowing the rotary drive to position and exchange finishing stones without a separate drive unit, reducing mass and power requirements by utilizing the existing rotary drive for both workpiece processing and stone positioning, and incorporating a controllable clamping device for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate drive unit is mounted on the stone turning unit to position finishing stones, then the finishing stones can be positioned in the required position, but the mass and installation space of the stone turning unit increase
Solution Approach 1:
The rotary drive of the workpiece holder is made to perform dual functions: driving the workpiece holder for workpiece processing and driving the stone turning unit for positioning finishing stones. By coupling the stone turning unit to the rotary drive of the workpiece holder, the same drive mechanism serves two purposes, eliminating the need for a separate drive unit on the stone turning unit and thereby reducing mass and installation space.

3Manufacturing precision
If the stone turning unit and finishing stone perform oscillating motion during processing, then the finishing process can be completed, but the drive power requirements increase
Solution Approach 1:
The rotary drive of the workpiece holder is made to perform dual functions: driving the workpiece holder for workpiece processing and driving the stone turning unit for positioning finishing stones. By coupling the stone turning unit to the rotary drive of the workpiece holder, the same drive mechanism serves two purposes, eliminating the need for a separate drive unit on the stone turning unit and thereby reducing mass and installation space.
Solution Approach 2:
The patent reduces the oscillating mass of the stone turning unit by eliminating the separate drive unit, which indirectly reduces the drive power required for oscillating motion. Additionally, the counterweight mechanism compensates for the changing mass distribution during stone exchange, reducing the power required to maintain oscillating motion.
4Weight of moving object
If the stone turning unit is made lighter by removing the separate drive unit, then the oscillating masses are reduced, but the positioning precision must be maintained
Solution Approach 1:
The control device monitors the position of the stone turning unit and adjusts the rotary drive accordingly to achieve precise positioning of finishing stones. The control device receives feedback about the position and makes real-time adjustments to maintain positioning precision even though the stone turning unit is lighter and coupled to the workpiece holder's rotary drive.

AI summary
A finishing machine with at least two finishing stones and a stone turning unit is proposed, in which the stone turning unit may be coupled to a rotary drive of the workpiece holder. A separate drive for the stone turning unit may thus be omitted, which results in a reduced weight of the stone turning unit and therefore lower drive power requirement of the stone turning unit and an improved processing quality.
