Peeling Machine Tool Holder Hook Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large peeling machines with tool holders over 100 mm diameter face challenges in smooth sliding due to strong elastic spiral springs, leading to increased labor, abrasion, and deformation issues, especially when cutting larger works where the tool holder fails to move radially outward due to increased sliding resistance and self-weight.
Innovation Solution
A peeling machine design featuring a hook member attached to the pressing member to prevent the tool holder from sliding radially inward by self-weight, with inclined pressing and pressure-receiving faces on the tool holder and pressing member, allowing smooth and stable sliding and reducing the need for strong force pressing, which enhances durability and prevents deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spiral spring with strong elasticity is used for large and heavy tool holders in large peeling machines, then the tool holder can be prevented from moving radially inward by self weight, but it becomes difficult to confirm smooth sliding during production process and preparation work, requiring much labor and time
Solution Approach 1:
The invention extracts the function of preventing radial inward movement from the spiral spring system and implements it through a separate hook member that engages with the tool holder. This separation allows the pressing member to slide smoothly under its own weight while the hook member independently prevents unwanted radial movement, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The invention segments the tool holder system into distinct functional components: the pressing member for radial adjustment, the hook member for preventing inward movement, and the spiral spring for maintaining pressing force. This segmentation allows each component to perform its specific function independently, making it easier to confirm smooth sliding while maintaining prevention of unwanted movement.
2Reliability
If a spiral spring with strong elasticity is used to press the tool holder, then radial inward movement is prevented, but abrasion is generated on the pressing face of the pressing member and the pressure-receiving face of the tool holder
Solution Approach 1:
The invention extracts the movement prevention function from the pressing interface and assigns it to the hook member. This allows the pressing faces to interact only with minimal friction for radial adjustment, while the hook member handles the prevention of radial inward movement, thereby eliminating abrasion on the pressing faces.
3Adaptability or versatility
If the tool holder is moved to the radial outer side to cut a larger work, then the work size capacity is increased, but sliding resistance increases due to fine cut chip, preventing the tool holder from moving radially outward
Solution Approach 1:
The hook member acts as a counteracting mechanism that releases its engagement with the tool holder when needed, allowing the tool holder to move radially outward despite increased sliding resistance from cut chips. The spiral spring provides the necessary force to overcome this resistance once the hook member releases.
4Stability of the object's composition
If the tool holder is not moved radially outward due to increased sliding resistance, then the pressing member and tool holder maintain their position, but the end portion of the work contacts the tool holder causing deformation and brake
Solution Approach 1:
The hook member serves as an intermediary mechanism that can be released to allow radial outward movement of the tool holder when work size increases. This prevents work deformation by enabling the tool holder to move away from the work end portion, while the spiral spring mediates the movement by providing the necessary force to overcome sliding resistance.
