Lockable Slide Clamping Mechanism for Auto Body Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for holding measurement objects, such as auto body components, lack precision in arranging them in a reference position due to clamping complexity and transverse displacement issues, affecting accuracy.
Innovation Solution
A lockable slide mechanism within the clamping device allows for linear adjustment of the clamping element parallel to the carrier head's advancement axis, enabling precise positioning without transverse displacement, and the clamping device can be pivoted and adapted to different measurement objects by embracing the carrier head with a forked part and using a stud with a circular cross-section and locking pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lever mechanism is used to pivot the clamping element against the carrier head, then the clamping device can adapt to different measurement objects, but transverse displacement occurs that displaces the measurement object and lowers clamping accuracy
Solution Approach 1:
The clamping device is divided into two independent adjustment mechanisms: a slide mechanism for linear adjustment parallel to the advancement axis, and a pivot mechanism for angular adjustment. This segmentation allows each mechanism to perform its specific function without causing transverse displacement, thereby maintaining clamping accuracy while adapting to different measurement objects.
Solution Approach 2:
A lockable slide mechanism is introduced as an intermediary between the carrier head and the clamping element. This slide mechanism enables linear adjustment of the clamping element's position parallel to the advancement axis, serving as a mediator that eliminates transverse displacement while still allowing the clamping device to adapt to different measurement objects through subsequent pivoting.
2Ease of operation
If the clamping element position is adjusted using a lever and spring force mechanism, then the clamping device can be operated easily, but the positioning precision is reduced due to transverse components
Solution Approach 1:
The clamping device incorporates a lockable slide mechanism that allows dynamic linear adjustment of the clamping element's position parallel to the advancement axis. The slide can be freely adjusted to the desired position and then locked in place, providing both ease of operation and high positioning precision by eliminating transverse displacement components that would otherwise occur with pure lever mechanisms.
3Adaptability or versatility
If the clamping device is designed with a forked part embracing the carrier head, then the device can be pivoted to adapt to different objects, but the structural complexity increases
Solution Approach 1:
The forked part is designed to integrate multiple functions: it embraces the carrier head, guides the slide mechanism, and serves as the pivot point for adapting to different measurement objects. By merging these functions into a single structural element, the design achieves adaptability without proportionally increasing overall structural complexity.
