Clamp Assembly for Safe Positioning of Small Plates in Cutting Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sawing machines require manual force to hold plates in position during cutting, which is difficult for small plates and poses safety risks due to proximity to the saw blade.
Innovation Solution
A cutting machine with a clamp assembly that includes a movable worktable and a clamp system with a sliding shaft, pressing member, abutting member, and adjusting member, allowing for secure positioning of the workpiece without manual force application, enhancing safety and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual force is applied to hold the plate in position during cutting, then the plate can be kept in position relative to the worktable, but the user's safety is compromised due to proximity to the saw blade
Solution Approach 1:
The patent introduces a clamp assembly as an intermediary device between the user's hand and the workpiece. The clamp assembly includes a clamp body with a clamp surface that contacts the workpiece, and a pressing member that applies force to the clamp body. This intermediary mechanism transfers the positioning function from direct manual contact to a mechanical device, eliminating the safety hazard of placing fingers near the saw blade while maintaining positioning accuracy.
2Reliability
If fingers are used to press the plate, then some positioning force can be applied, but the positioning effect is insufficient for small or narrow plates
Solution Approach 1:
The clamp assembly is segmented into multiple functional components: a clamp body with clamp surface for contacting the workpiece, a pressing member for applying force, a chute for guiding movement, and an adjusting member for controlling the pressing force. This segmentation allows each component to perform its specific function efficiently, providing sufficient positioning force for small or narrow plates while maintaining ease of operation through the coordinated action of these components.
Solution Approach 2:
The clamp body acts as an intermediary between the pressing member and the workpiece. The clamp surface of the clamp body provides a dedicated contact area that concentrates the pressing force effectively on small or narrow plates, achieving reliable positioning that cannot be obtained by direct finger pressure alone.

AI summary
A cutting machine with clamp assembly includes a saw blade, a worktable, and a clamp assembly. The worktable is adjacent to the saw blade and can move along a processing axis relative to the saw blade. The worktable includes a tabletop facing the saw blade, a processing area set on the tabletop and extending along the processing axis and corresponding to the saw blade, and a chute recessed on the tabletop and extending in the direction of the processing area. The clamp assembly can be operated to move along the chute. The present invention uses the clamp assembly to firmly press against the workpiece, thereby assisting the positioning of the workpiece and ensuring the safety of the user.
