Multi-Directional Vise Structure for Precise Specimen Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices struggle to stably fix and cut specimens, particularly those with circular outer surfaces, leading to difficulties in precise cutting and maintaining exact dimensions, especially when cutting in multiple directions, which is necessary for inspecting internal welds.
Innovation Solution
A multi-directional vise device with a first and second body part, jig parts, and a compression part that adjusts the gap between them, allowing for firm fixation and guiding cuts in multiple directions, including a cut part and an upper plate with a guide part that rotates to facilitate precise cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing means (clamp) are used to fix the specimen, then the specimen can be held in place, but the specimen cannot be fixed stably and firmly, resulting in inability to control force and vibration caused by the saw
Solution Approach 1:
The vise device is divided into a first body part and a second body part that can move relative to each other. The first body part includes a first clamp for fixing the specimen, while the second body part includes a second clamp and can be moved to apply additional clamping force. This segmentation allows the device to provide both initial fixation and enhanced stabilization, resolving the contradiction between reliable fixation and cutting precision.
Solution Approach 2:
The second body part is designed to be movable relative to the first body part, allowing dynamic adjustment of clamping force. The compression part enables the user to move the second body part toward the first body part to apply additional force on the specimen, providing dynamic control over the fixation stability during the cutting process.
2Ease of operation
If the specimen is fixed to one position using conventional means, then the fixing process is simple, but it is difficult to cut the specimen in multiple directions while maintaining exact dimensions and shape
Solution Approach 1:
The vise device incorporates guide parts with guide grooves that can guide cutting tools in multiple directions (first direction parallel to the specimen's length, and second direction vertical to the length). The first and second clamps can independently adjust to accommodate specimens of different sizes and shapes. This multi-functionality allows the device to maintain ease of operation while providing versatility for cutting in multiple directions.
Solution Approach 2:
The device adds a vertical dimension (second direction) to the traditional horizontal clamping arrangement by introducing guide grooves that extend in both horizontal and vertical directions. This dimensional expansion allows the specimen to be guided and cut in multiple directions while maintaining the simplicity of the fixed-position clamping mechanism.
3Device complexity
If manual cutting using a hacksaw is used, then no special device is needed, but it takes a lot of time
Solution Approach 1:
The vise device acts as an intermediary between the simple hacksaw and the cutting task. By providing stable fixation through the first and second clamps and precise guidance through the guide grooves, the device enables the user to efficiently use a simple hacksaw, significantly reducing cutting time while maintaining equipment simplicity.
4Length of moving object
If the specimen has a small diameter, then it is compact and easy to handle, but it is difficult to directly check the inside and requires cutting in multiple directions
Solution Approach 1:
The guide parts with pre-formed guide grooves are prepared in advance on the first and second body parts. These guide grooves are specifically designed to facilitate cutting in multiple directions (horizontal and vertical) to access the internal welded part of small-diameter specimens. This preliminary preparation of guidance paths makes it easy to perform multi-directional cutting for inspection purposes.
