Brushing Device Axial Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brushing devices for machine tools require manual intervention and machine stoppage for periodic readjustment of fibre rods, which is inefficient and complicates the use of standard tool holding fixtures due to complex designs involving rotatable parts.
Innovation Solution
A brushing device with a clamping mechanism that allows non-positive connection adjustment through an axially adjustable clamping cone and springs, enabling simple and automated adjustment of fibre rod protrusion without rotating parts, integrated with a standard tool holding fixture for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a locking screw with longitudinal slot is used for adjusting fibre rod protrusion, then the adjustment can be performed manually, but the machine must stop and manual intervention is required
Solution Approach 1:
The brushing device performs self-adjustment of the fibre rod protrusion through an automated axial displacement mechanism. The protective sleeve is axially displaced relative to the fibre rods by a displacement device, automatically compensating for wear without requiring manual intervention or machine stoppage, thus the system adjusts itself during continuous operation
Solution Approach 2:
The invention transforms the static adjustment mechanism into a dynamic one. Instead of fixed locking screws, the protective sleeve can be continuously or periodically axially displaced to maintain the desired protrusion of fibre rods, enabling adjustment during machine operation rather than requiring static stoppages
2Extent of automation
If a nut-spindle combination is used for mechanical readjustment, then automated adjustment is enabled, but the design becomes complex and standard tool holding fixtures cannot be used
Solution Approach 1:
The invention removes the complex rotatable nut-spindle mechanism from the brushing device design. Instead, it uses a simpler axial displacement mechanism that can be integrated directly into the tool holder, extracting the unnecessary rotational components while retaining the essential adjustment function
Solution Approach 2:
The simplified axial displacement mechanism is designed to be compatible with standard tool holding fixtures, allowing the brushing device to be universally mounted on conventional machine tools without requiring specialized or complex adapter mechanisms
3Device complexity
If manual adjustment with locking screw is used, then the construction remains simple, but frequent stoppages and manual interventions are required
Solution Approach 1:
The brushing device maintains continuous operation by enabling adjustment of fibre rod protrusion during machine running. The axial displacement mechanism allows the protective sleeve to be moved and locked at different positions without stopping the machine, ensuring uninterrupted productive action

AI summary
The brushing device contains a bundle of fiber rods (1), which are arranged parallel to one another, and a protective sleeve (2), which encloses the fiber rods. Once fiber rods (1) have become worn, the protective sleeve (2) is able to be axially adjusted, so that the free ends of the fiber rods (1) protrude beyond the protective sleeve (2) by a desired amount. A first component (4) connected to the fiber rods (1) and a further, second component (8) connected to the protective sleeve (2) are detachably connected to one another, in a non-positively locking manner, by a clamping mechanism (3, 5, 11).
