Adjustable Angle Head Holder Positioning for Different Spindle Diameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional angle head holders require multiple positioning devices of different specifications to accommodate spindles of varying diameters, increasing manufacturing costs due to a fixed distance between the positioning pin and the spindle center.
Innovation Solution
An angle head holder with an adjustable positioning device featuring a detachable connecting block, lever pins, and an extension block, allowing the distance between the connecting block and fixing ring to be adjusted, ensuring the positioning pin remains limited by the constraining groove regardless of spindle diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-distance positioning device is used, then the positioning pin can be securely limited by the constraining groove, but the angle head holder cannot accommodate spindles of different diameters
Solution Approach 1:
The positioning device transitions from a fixed configuration to a dynamically adjustable one. The distance between the positioning pin and the fixing ring can be changed by adjusting the position of the connecting block along the fixing ring, allowing the device to adapt to different spindle diameters while maintaining secure positioning.
Solution Approach 2:
The key parameter being changed is the distance between the positioning pin and the fixing ring. By allowing this distance to be adjusted, the positioning device can accommodate various spindle diameters. The connecting block serves as the adjustable element that changes this critical parameter.
2Adaptability or versatility
If multiple positioning devices of different specifications are prepared, then spindles of different diameters can be accommodated, but manufacturing costs increase
Solution Approach 1:
A single positioning device is designed to perform multiple functions by accommodating different spindle diameters. The adjustable connecting block enables one device to replace multiple fixed-specification devices, reducing inventory requirements and manufacturing costs while maintaining versatility.
Solution Approach 2:
The positioning device incorporates adjustable elements that allow it to adapt to different specifications. This dynamic capability eliminates the need to manufacture and stock multiple fixed-specification devices, thereby reducing overall manufacturing costs while maintaining adaptability.
3Device complexity
If the distance between the positioning pin and spindle center is unchangeable, then the positioning device structure is simple, but it requires changing the positioning device for different spindle diameters
Solution Approach 1:
The positioning device incorporates adjustable elements that allow it to adapt to different specifications. This dynamic capability eliminates the need to manufacture and stock multiple fixed-specification devices, thereby reducing overall manufacturing costs while maintaining adaptability.
Solution Approach 2:
The positioning device is divided into separable components, particularly the connecting block that can be positioned at different locations. This segmentation allows for adjustment of the positioning pin distance without redesigning the entire device, balancing structural simplicity with adaptability.

AI summary
An angle head holder is installed on a spindle having a positioning block mounted on its outer surface with a constraining groove. The angle head holder includes a body base, a driving shaft, a holder assembly, and a positioning device. The driving shaft and the holder assembly are disposed in the body base. The positioning device has a fixing ring and an adjusting assembly. The fixing ring is sleeved on the body base and has a receiving slot. The adjusting assembly has a connecting block, a positioning pin, and at least one lever pin. The connecting block is mounted to the fixing ring and has a receiving groove. The positioning pin protrudes out of the receiving groove, is limited by the constraining groove, and has a retaining groove. The at least one lever pin is mounted in the receiving slot and the retaining groove.
