Multi-Target Holder Layout for Compact Cutting Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting machines are limited in their ability to retain multiple processing targets without increasing the size of the retention structures, as they require extra space for pin insertion and removal, leading to larger machine sizes.
Innovation Solution
The cutting machine design incorporates a spindle, a holder, and a rotation support with detachable holders that allow independent fixing of processing targets, reducing the need for extra space and minimizing the overall size of the retention structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin is inserted into a fixing hole to attach processing targets to the retention member, then the processing targets can be securely retained, but extra space is required for pin insertion and removal, increasing the size of the retention member
Solution Approach 1:
The fixing pin is inserted through the processing target and engages with fixing holes in both the first holder and second holder simultaneously. The pin acts as a common fastening element that nests through multiple components (processing target, first holder, second holder), securing them together in a compact arrangement without requiring additional insertion space.
Solution Approach 2:
The first holder and second holder are positioned adjacent to each other with their fixing holes aligned, allowing a single fixing pin to secure both holders to the processing target simultaneously. This merging of fixing operations eliminates the need for separate insertion spaces that would be required if the holders were positioned farther apart.
2Productivity
If the retention member is designed to hold multiple processing targets, then the machine capacity is improved, but the size of the retention member increases
Solution Approach 1:
The retention member is divided into multiple holders (first holder, second holder, third holder, fourth holder) that can be independently positioned and attached to processing targets. Each holder can secure a processing target, allowing multiple targets to be retained simultaneously in a compact configuration rather than requiring a single large retention structure.
Solution Approach 2:
Multiple holders are arranged in an overlapping or adjacent configuration where fixing pins from different holders can engage with aligned fixing holes. This nesting arrangement allows multiple processing targets to be secured in a compact space, increasing machine capacity without proportionally increasing the retention member size.
3Ease of operation
If extra space is provided for pin insertion and removal, then ease of operation is improved, but the size of the retention member increases
Solution Approach 1:
The holders are positioned asymmetrically with offset fixing holes that allow pins to be inserted and removed from accessible directions. The first holder and second holder have their fixing holes positioned to allow pin manipulation from the side, while the third and fourth holders are arranged to provide similar access, maintaining ease of operation without requiring symmetric spacing that would increase overall size.

AI summary
A cutting machine includes a holder located below a spindle to hold processing targets, and an adaptor connected to a rotation shaft to rotatably support the holder. The holder includes a first holder fixed to the adaptor and including a pin insertion hole to which a fixing pin attached to a processing target is fixed, and a second holder detachably attached to the first holder and including a pin insertion hole at a position facing the pin insertion hole. The fixing pin extends in a Y-axis direction. In the Y-axis direction, a distance between a processing target fixed to the pin insertion hole and a processing target fixed to the pin insertion hole is shorter than a length of the fixing pin.
