Curved Guide Clamping Claw for Variable Height Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamping claws are limited in flexibility, requiring the clamping surface and support surface to be at the same height and aligned perpendicular to the clamping claw's longitudinal direction, restricting the ability to clamp workpieces with surfaces at different heights or angles.
Innovation Solution
A clamping claw with a curved displacement path for the clamping piece relative to the base body, allowing the clamping direction to be adjusted by pivoting a pressure piece, enabling the clamping surface and support surface to be at different heights and angles, and incorporating a guide device with curved guiding channels to facilitate this adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the clamping element is displaceable along a straight path relative to the base body, then the clamping direction is precisely perpendicular to the longitudinal direction of the base body, but the clamping surface and support surface must be at the same height, limiting flexibility
Solution Approach 1:
The guide device incorporates a curved guide channel that forces the clamping element to follow a curved displacement path instead of a straight line. This curvature enables the clamping element to change its angular orientation relative to the base body during displacement, allowing the clamping direction to deviate from the traditional perpendicular alignment and accommodate workpieces at different height levels and angles.
Solution Approach 2:
The system transitions from a static, fixed-angle clamping mechanism to a dynamic one where the clamping element's angular position changes continuously along the curved guide path. This dynamic adjustment capability allows the clamping jaw to adapt to various workpiece configurations while maintaining precise clamping force application.
2Ease of operation
If the clamping surface and support surface are at the same height, then the clamping direction is perpendicular to the base body, but the device cannot accommodate workpieces with surfaces at different heights or angles
Solution Approach 1:
The curved guide channel mechanism provides multi-functionality by enabling the same clamping device to handle both standard workpieces (with surfaces at the same height) and non-standard workpieces (with surfaces at different heights or angles). The guide channel's curvature radius and orientation can be designed to accommodate a range of workpiece configurations, making the device universally applicable.
Solution Approach 2:
The system changes the geometric parameters of the displacement path from linear to curved, which fundamentally alters the relationship between the clamping element's position and orientation. This parameter change enables the clamping element to achieve different angular positions at different points along the guide channel, accommodating varying surface configurations.
3Adaptability or versatility
If a curved displacement path is used for the clamping element, then flexibility for different height levels and angles is improved, but the guide device structure becomes more complex
Solution Approach 1:
The guide device is segmented into a base body and a separate guide channel component. This segmentation allows the curved guide channel to be designed and manufactured independently, simplifying the overall structure. The guide channel can be shaped to provide the necessary curvature while maintaining a relatively simple attachment to the base body, reducing overall structural complexity.
Solution Approach 2:
The guide channel acts as an intermediary element that mediates between the straight-line motion of the clamping element and the curved displacement path required for flexibility. By introducing this intermediate guide structure, the system achieves complex motion patterns without requiring complex direct connections between the clamping element and base body.
