Jig Chuck Structure for Stable Attachment and Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching and detaching upper jigs in industrial machinery result in unstable relative positional relationships and difficulty in positioning due to gaps and backlash, leading to a heavy burden on operators.
Innovation Solution
A structure with a grasping portion on at least one of the first and second fixing members, allowing smooth movement and stable attachment/detachment by adjusting screw degrees, using features like anti-rotation members, locking members, and elastic elements to maintain positional stability even when screws are loosened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper jig and fixing members are integrally treated as a structure, then the attachment/detachment process becomes simpler, but gaps and backlash occur causing unstable relative positional relationships
Solution Approach 1:
The invention separates the upper jig from the fixing members, allowing independent positioning of each component. The upper jig can be positioned on the industrial machine while the fixing members are separately positioned, eliminating the instability caused by integral treatment.
Solution Approach 2:
The invention introduces a positioning mechanism as an intermediary between the upper jig and fixing members. This positioning mechanism maintains stable relative positional relationships even when the screw connections are loosened, acting as a mediator that prevents gaps and backlash from affecting positioning accuracy.
2Ease of operation
If the screw degree is loosened for detachment, then the upper jig can be separated, but positioning of the second fixing member becomes difficult due to gaps
Solution Approach 1:
The positioning mechanism is pre-configured to maintain relative positional relationships before detachment occurs. This preliminary positioning ensures that even when screws are loosened, the components remain in known, easily locatable positions, eliminating positioning difficulties during detachment.
Solution Approach 2:
The positioning mechanism automatically maintains stable relative positional relationships without requiring additional positioning operations. The system self-regulates to prevent gaps and backlash from affecting positioning, making the detachment process easier without sacrificing positioning accuracy.
3Productivity
If the upper jig is grasped for attachment/detachment, then the process can be performed, but the heavy burden on operator arises from positioning difficulty
Solution Approach 1:
The positioning mechanism automatically maintains stable relative positional relationships, allowing the upper jig to be easily grasped and moved without requiring precise manual positioning by the operator. This self-positioning capability significantly reduces operator burden while maintaining productivity.

AI summary
A structure that is mounted to industrial equipment. This structure includes a jig, a first fixing member and a second fixing member, and a grip part. The industrial equipment has an attachment/detachment region for attaching and detaching the jig. The attachment/detachment region has a first space. The jig has a second space. The first fixing member is accomodatable in the first space. The second fixing member is accomodatable in the second space. The second fixing member is configured so that the jig can be attached to and detached from the attachment/detachment region by adjusting the degree of helical engagement of the first and second fixing members. The grip part is provided to at least one of the first fixing member and the second fixing member, and is configured grippable such that, in a state in which the degree of helical engagement has been loosened, the structure can smoothly be moved.
