Motorized Boring Tool Insert Adjustment for Fast Diameter Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional boring tools require manual adjustment of hole diameters, which is time-consuming and inefficient in productive environments, as operators need to physically interact with the machine or remove the tool to adjust the cutting edge's position.
Innovation Solution
A boring tool with a motor member and slider mechanism that allows transverse movement of the cutting insert, controlled by a microcontroller and powered by an internal energy source, enabling adjustments of the cutting edge's distance to the rotation axis and thus the hole radius, facilitated by wireless communication for remote operation and high-resolution positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual adjustment of the cutting edge position is used, then the tool structure remains simple, but the productivity decreases and time loss increases
Solution Approach 1:
The boring tool performs adjustment operations automatically through a motor member driven by a power source, eliminating the need for operator intervention. The control unit enables automatic control of the motor member to move the slider member, allowing the tool to adjust its own cutting diameter without external manual operation.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated motor-driven system. A motor member connected to the slider member through a transmission mechanism (such as a ball screw) substitutes for manual screw turning, converting rotational motor motion into linear slider motion for precise cutting edge positioning.
2Adaptability or versatility
If the cutting edge position is fixed, then the tool structure is simpler, but the adaptability decreases
Solution Approach 1:
The boring tool incorporates a dynamic adjustment mechanism where the slider member can move along the rotation axis to change the cutting diameter. The motor member provides powered motion to the slider, enabling continuous adjustment of the cutting edge position to adapt to different workpiece requirements.
Solution Approach 2:
The adjustable mechanism allows a single boring tool to perform multiple cutting operations at different diameters. By moving the slider member along the rotation axis, the same tool can accommodate various cutting insert positions and create different hole sizes, eliminating the need for multiple fixed-diameter tools.
3Productivity
If automated motor-driven adjustment is implemented, then productivity improves, but the device complexity increases
Solution Approach 1:
The motor member is positioned inside the tool body, and the slider member moves within the tool body structure. The transmission mechanism components are nested within the compact tool housing, allowing the automated adjustment system to be integrated without significantly increasing the external dimensions of the boring tool.
Solution Approach 2:
The control unit integrates the power source control and motor member control functions within the tool structure. The transmission mechanism combines rotational motor motion with linear slider motion in a single integrated system, reducing the number of separate components and simplifying the overall device architecture.

AI summary
A boring tool includes a tool body rotatable around a central rotation axis. A slider member is arranged movably inside the tool body along a path extending transversely to the rotation axis. An insert pocket is associated with the slider member to move therewith and configured to receive a cutting insert with a cutting edge and which projects from the tool body transversely to the rotation axis. A motor member is connected to the slider member and controllable to move the slider member transversely to the rotation axis for changing the distance of the cutting edge to the rotation axis. The motor member is arranged inside the tool body together with the slider member in a cutting part 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.
