Dual-Holder Cutting Machine for Compact Multi-Target Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting machines are limited in their ability to retain multiple processing targets due to the need for extra space to accommodate pins, leading to an increase in the size of the retention member and the entire machine.
Innovation Solution
The cutting machine design includes a detachable second holder that can be independently fixed to a first holder, allowing for separate attachment of processing targets without considering interference, thereby reducing the necessary space and preventing an increase in size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin is inserted in a fixing hole to attach a processing target to the retention member, then the processing target can be securely retained, but an extra space is required that increases the size of the retention member and the entire cutting machine
Solution Approach 1:
The retention member is divided into a first holder and a second holder that can be independently assembled. The first holder includes first fixing portions for attaching processing targets, while the second holder includes second fixing portions. This segmentation allows each holder to be compact while collectively providing multiple retention positions without requiring excessive space for pin insertion and removal operations.
Solution Approach 2:
The second holder is detachably attached to the first holder, creating a nested or stacked configuration. This nesting arrangement allows the holders to be positioned close together in the second direction (vertical direction), minimizing the overall space required while still providing independent fixing portions for multiple processing targets.
2Quantity of substance
If multiple processing targets are retained using pins that require insertion and removal space, then multiple targets can be processed, but the distance between targets must be greater than the pin length, increasing the overall size
Solution Approach 1:
By dividing the retention member into separate first and second holders with independent fixing portions, the system can retain multiple processing targets in a compact arrangement. Each holder can be positioned independently, allowing the distance between targets to be determined by the holder dimensions rather than pin length requirements.
Solution Approach 2:
The holders are arranged in the second direction (vertical dimension) with detachable attachment, allowing multiple processing targets to be retained in a stacked configuration. This dimensional arrangement reduces the horizontal space requirements and allows closer positioning of targets compared to linear pin-based retention.

AI summary
A cutting machine 10 includes a holder 50 located below a spindle 30 to hold processing targets 8, and an adaptor 45 connected to a rotation shaft 44 to rotatably support the holder 50. The holder 50 includes a first holder 60 fixed to the adaptor 45 and including a pin insertion hole 61H to which a fixing pin 8 attached to a processing target 5 is fixed, and a second holder 70 detachably attached to the first holder 60 and including a pin insertion hole 71H at a position facing the pin insertion hole 61H. The fixing pin 8 extends in a Y-axis direction. In the Y-axis direction, a distance TL between a processing target 5 fixed to the pin insertion hole 61H and a processing target 5 fixed to the pin insertion hole 71H is shorter than a length PL of the fixing pin 8.
