Adjustable Collet Chuck Alignment for Precise Lathe Concentricity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collet and tooling alignment systems in lathes suffer from imprecision, loss of alignment during use, and limited adjustability, leading to lopsided and imprecise workpieces.
Innovation Solution
An adjustable collet holder that connects to a lathe and features a collet receiver adjustable along the x, y, and z axes, utilizing hold-down screws, angular set screws, and radial set screws for precise alignment and concentricity adjustments, allowing for both angular and lateral adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed collet holder is used, then the structure is simple, but the alignment precision with the spindle deteriorates
Solution Approach 1:
The collet holder transitions from a fixed structure to a dynamically adjustable one, allowing movement along the X, Y, and Z axes. The holder can be positioned at different locations and orientations relative to the spindle, with set screws locking it in place once optimal alignment is achieved. This dynamic capability resolves the contradiction by enabling precise alignment adjustments while maintaining structural simplicity through modular design.
Solution Approach 2:
The collet holder is divided into separable components including the holder body, set screws, and collet receiver. This segmentation allows independent adjustment of each component to achieve precise alignment while keeping the overall structure relatively simple. The modular approach enables fine-tuning of alignment without requiring complex integrated mechanisms.
2Measurement precision
If an adjustable collet holder is used, then the alignment precision improves, but the reliability of maintaining alignment deteriorates
Solution Approach 1:
The set screws are designed to be adjusted beforehand to achieve the desired alignment position, and then tightened to lock the holder in place. This preliminary adjustment followed by securing prevents the alignment from being thrown out during use. The holder can be finely tuned for precise alignment, and the set screws maintain this alignment reliably during machining operations.
3Adaptability or versatility
If a simple collet holder is used, then the device complexity is low, but the adjustability is limited
Solution Approach 1:
The collet holder incorporates adjustable elements that allow movement and repositioning along multiple axes (X, Y, Z directions). Set screws enable the holder to be positioned at various locations and angles relative to the spindle, providing high adaptability. The structure remains relatively simple through the use of basic mechanical adjustment mechanisms rather than complex automated systems.

AI summary
An adjustable collet holder for use with a lathe is provided. The adjustable collet holder may include a set of hold down screws to hold it in place once adjusted. Adjustment may be achieved by adjusting multiple set screws to change both angular and concentricity orientations of a collet receiver relative to a body of the collet holder.
