Motorized Boring Tool Slider for Fast Diameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual adjustment of boring tool diameters is time-consuming and inefficient in high-productivity environments, as it requires operators to physically interact with the machine or remove the tool, leading to reduced productivity and increased risk.
Innovation Solution
A compact design where a motor member is integrated inside a hollow slider member within the tool body, allowing for substantial adjustments of the cutting edge's distance from the rotation axis, enabled by a microcontroller and wireless communication for automated control, and a sensor for high-resolution positioning, eliminating the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual adjustment of boring tool diameters is used, then the tool structure remains simple, but productivity decreases and adjustment time increases
Solution Approach 1:
The motor member is nested inside the hollow slider member, creating a compact integrated assembly. This allows the adjustment mechanism to be incorporated within the existing tool body structure without requiring additional external components, thereby improving productivity through automated adjustment while minimizing increases in device complexity
Solution Approach 2:
The motor member enables the slider member to automatically adjust the cutting edge position without manual intervention. The system serves itself by using an integrated motor to perform the adjustment function that previously required operator action, thus increasing productivity while keeping the overall structure relatively simple
2Adaptability or versatility
If the motor member is arranged outside the tool body, then adjustment range increases, but the tool body size and complexity increase
Solution Approach 1:
By nesting the motor member inside the hollow slider member, the adjustment mechanism is compacted into the existing tool body volume. This allows substantial adjustment ranges to be achieved without increasing the overall tool body size, as the motor and slider share the same internal space rather than requiring separate external mounting
Solution Approach 2:
The slider member moves along a path that extends transversely from the rotation axis, utilizing the internal hollow space of the slider member in a different spatial dimension. This allows the motor to be positioned inside the tool body while still achieving substantial radial adjustment of the cutting edge
3Productivity
If automated adjustment is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The motor member is configured to move the slider member automatically without requiring complex external control systems. The integrated nature of the motor and slider allows for simple direct drive or basic transmission mechanisms, achieving automated adjustment with minimal control complexity while significantly improving productivity compared to manual operation

AI summary
A boring tool comprises a tool body (2) rotatable around a central rotation axis (C). A slider member (5) is arranged movably inside the tool body along a path (P) extending transversely to the rotation axis (C). An insert pocket is associated with the slider member to move therewith and configured to receive a cutting insert (9) with a cutting edge and which projects from the tool body transversely to the rotation axis (C). A motor member (12) is connected to the slider member and controllable to move the slider member transversely to the rotation axis (C) for changing the distance of the cutting edge (11) to the rotation axis (C). The motor member (12) is arranged inside the tool body together with the slider member in a cutting part (14) of the tool body at a front end thereof. The motor member is arranged in parallel with the transversal extension of the slider member along said path.
