Rotary Tool Adjustment Circuit Layout for Compact Spindle Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining systems require a large installation space for adjustment devices, leading to instability in main drive elements like tool spindles and reduced machining efficiency, especially when dealing with workpieces of varying sizes and complex contours.
Innovation Solution
The adjustment device features a compact design with a circuit carrier element that reduces its axial dimension by connecting surface points outside the circuit carrier element, allowing for reduced co-torque on the main drive element, increased machining speed, and improved accessibility, while maintaining stability and allowing for larger workpiece sizes.

Engineering Contradiction Analysis
1Length of moving object
If the adjustment device uses a conventional circuit carrier element design, then the control circuit can be properly formed, but the axial dimension of the adjustment device becomes large
Solution Approach 1:
The circuit carrier element is designed with a circumferential arrangement of circuit components around the drive unit, transforming the conventional axial layout into a radial/dimensional configuration. This allows the control circuit to wrap around the drive unit in a circumferential direction, significantly reducing the axial dimension of the adjustment device while maintaining all necessary control functions
2Stability of the object's composition
If the adjustment device has a larger axial dimension, then the control circuit can be properly arranged, but the stability of the main drive element decreases
Solution Approach 1:
The circuit carrier element is positioned to surround the drive unit in a nested configuration, with the control circuit components arranged circumferentially around the motor and gearbox assembly. This nested arrangement consolidates the adjustment device into a compact axial profile, improving the stability of the main drive element while housing all control circuitry within the existing radial envelope
3Area of stationary object
If the adjustment device has a larger axial dimension, then the control circuit can be properly arranged, but the machining space is reduced
Solution Approach 1:
By reconfiguring the control circuit arrangement from an axial layout to a circumferential layout around the drive unit, the adjustment device achieves a compact axial profile. This dimensional transformation frees up axial machining space while maintaining all control functions, allowing for larger workpiece accommodation and improved accessibility
4Force
If the circuit carrier element is arranged conventionally, then the control circuit can be formed, but the co-torque on the main drive element is high
Solution Approach 1:
The control circuit components are arranged circumferentially around the drive unit rather than axially, positioning the circuit carrier element in a radial configuration. This dimensional change optimizes the torque transmission path and reduces co-torque on the main drive element by minimizing the moment arm of the control circuit assembly

AI summary
In order to provide an adjustment device (1), which can be driven in rotation about a longitudinal axis (2), for adjusting a cutting tool, comprising a cutting tool carrier element (3) mounted for carrying out an adjusting movement (6), a drive unit (13, 13b) for driving the cutting tool carrier element (3) and a circuit carrier element (200), which has a surface region facing the drive unit (13, 13b), for forming at least one electronic control circuit (500, 510, 520, 530) provided for controlling the drive unit (13, 13b), 13b), which allows an improved compact design so that instabilities of the main drive element, in particular a tool spindle, are better avoided and the machining space is better utilised, it is proposed that two surface points (600, 610) of the surface area (220) can be connected outside the circuit carrier element (200) by a connecting straight line (620), the end points of which are the surface points (600, 610).
