Chuck-Claw Guide Structure for Fast Multi-Direction Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chuck-claw guide structures face challenges in quickly aligning and inserting claws into attachment grooves due to the distance and inclination of positioning plates and chuck bases, leading to prolonged adjustment times.
Innovation Solution
A chuck-claw guide structure featuring a guide-space delimiting part with contact surfaces and regulation parts that guide and regulate the claw in multiple directions, allowing for precise alignment and quick insertion into the attachment groove, utilizing a movable regulation support part and threaded engagement for efficient alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a positioning plate is installed on a base of a machine tool disposed on an outer circumferential side of a chuck, then a claw can be guided to an attachment groove, but it takes a long time to adjust the alignment of the attachment position of the jaw holder and the attachment groove of the chuck
Solution Approach 1:
The guide structure is merged with the chuck body by providing the guide-space delimiting part as an integral component of the chuck. This eliminates the need for separate positioning plates and jaw holders, allowing the claw to be directly guided from the guide space into the attachment groove without complex alignment adjustments between multiple components.
Solution Approach 2:
The guiding function is extracted from external components (positioning plate and jaw holder) and integrated into the chuck body itself through the guide-space delimiting part. This extraction simplifies the system by removing the need for separate alignment-adjustable components while maintaining the guiding capability.
2Adaptability or versatility
If the positioning plate and chuck are distant from each other and/or the base of the machine tool is inclined, then alignment adjustment becomes necessary, but this increases the complexity of the device
Solution Approach 1:
Multiple functions (guiding, positioning, and alignment compensation) are merged into the single guide-space delimiting part integrated with the chuck body. This eliminates the need for separate positioning plates and multiple adjustment mechanisms, reducing device complexity while maintaining adaptability to different installation conditions.
Solution Approach 2:
The regulation part is designed to be movable along the guide space, allowing dynamic adjustment of the claw's position in the second direction. This dynamic regulation capability provides adaptability to different installation conditions without requiring complex external positioning mechanisms.
3Manufacturing precision
If multiple regulation parts are provided in the guide space at positions different from each other, then the claw can be regulated in multiple directions, but this increases the number of components
Solution Approach 1:
The positioning function is segmented into two distinct directions: the contact surface regulates the claw in the first direction (along the attachment groove), while the regulation part regulates the claw in the second direction (perpendicular to the first direction). This segmentation of regulatory functions into orthogonal directions achieves precise positioning without requiring multiple complex regulation parts.

AI summary
A chuck-claw guide structure includes a guide-space delimiting part that delimits a guide space in communication with an attachment groove, and a regulation part provided on the guide-space delimiting part. The guide-space delimiting part has a contact surface configured to regulate the claw in contact therewith at a position along the attachment groove in a first direction. The regulation part is configured to regulate the claw at a position along the attachment groove in a second direction different from the first direction.
