Swing Clamp Arm Positioning via Stepped Rod and Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swing clamp apparatuses require significant workload to position and fix the clamp arm on the clamp rod, especially when frequently replacing the clamp arm for different clamping objects, as they lack a reliable method for rotational positioning.
Innovation Solution
The introduction of an attachment block with clamping force transmission pins that allow the clamp arm to be detachably attached and positioned on the clamp rod, enabling simple and reliable alignment and attachment by engaging/disengaging the pins orthogonal to the axis, reducing the workload of replacing the clamp arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clamp arm is directly fixed to the clamp rod using bolts, then the clamp arm can be securely attached, but the workload to position and fix the clamp arm increases significantly when replacing it for different clamping objects
Solution Approach 1:
The clamp rod is divided into multiple sections with different diameters, creating distinct positioning zones. The clamp arm has corresponding stepped structures that fit onto these sections, enabling quick identification and attachment at the correct position without complex measurement or alignment procedures.
Solution Approach 2:
The attachment block is pre-positioned on the clamp rod at the desired location before the clamp arm is attached. This preliminary positioning ensures that when the clamp arm is later replaced, it will be at the correct position, eliminating the need for re-positioning and reducing replacement time.
2Adaptability or versatility
If the clamp arm is frequently replaced for different clamping objects, then adaptability is improved, but the workload and complexity of positioning and fixing increase
Solution Approach 1:
Both the clamp rod and clamp arm are segmented with stepped structures that create a simple mechanical interface. This segmentation provides multiple predetermined positions without requiring complex positioning mechanisms, maintaining simplicity while enabling frequent replacement for different applications.
Solution Approach 2:
The stepped structure design creates a universal interface that can accommodate different clamp arm configurations and sizes. The same basic attachment mechanism works for various clamping objects, reducing the need for specialized positioning systems for each application.
3Manufacturing precision
If a reliable rotational positioning method is implemented, then positioning precision is improved, but the device complexity increases
Solution Approach 1:
The rotational positioning is achieved through stepped structures with specific diameter variations along the clamp rod. Each step represents a predetermined angular or radial position, providing reliable positioning without requiring complex rotational mechanisms, sensors, or adjustment devices.
Solution Approach 2:
The stepped structure design allows the clamp arm to self-position on the clamp rod through its own geometric features. The matching stepped profiles automatically align the components when assembled, eliminating the need for external positioning mechanisms or complex adjustment procedures.

AI summary
A swing clamp apparatus is provided in which the clamp arm is positioned and attached to a clamp rod at a desired position in a simple and reliable manner and the clamp arm replacement workload is certainly reduced. The swing clamp apparatus comprises an attachment block fixed to the leading end of a clamp rod and to which a clamp arm is detachably attached and a pair of clamping force transmission pins inserted in the attachment block and clamp arm in the direction parallel to the orthogonal direction to the axis for coupling the positioned clamp arm to the attachment block in an integrated manner.
