Material Testing Machine Sliding Fixture Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material testing machines with extruded aluminum support poles for concealing drive screws are costly due to the need for T-shaped slots for mounting fixtures.
Innovation Solution
The material testing machine incorporates sliding attachment units on support poles that extend along the longitudinal axis, allowing for adjustable mounting fixture placement without the need for slots in the pole covers, reducing manufacturing costs and enabling versatile fixture positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If T-shaped slots are formed in the surface of extruded aluminum pole covers for mounting fixtures, then mounting fixtures can be attached, but the manufacturing cost becomes expensive
Solution Approach 1:
The invention divides the pole cover into two separate functional components: the pole cover itself and a detachable support pole. The mounting function is segmented and transferred to the support pole, which can be attached to or removed from the pole cover. This segmentation allows the pole cover to be manufactured without expensive T-shaped slots, while the support pole provides the mounting capability through its own attachment mechanism.
Solution Approach 2:
The mounting function is extracted from the pole cover and transferred to a separate support pole component. The support pole is provided with attachment holes that allow mounting fixtures to be secured, while the pole cover maintains a simple extruded aluminum structure without requiring complex slot formations. This extraction eliminates the need for expensive slot machining in the pole cover.
2Adaptability or versatility
If support poles are formed by extrusion with T-shaped slots for mounting fixtures, then fixtures can be mounted, but the pole cover design becomes complex
Solution Approach 1:
The pole cover structure is segmented into the main pole cover body and separate support poles. The support poles are attached to the pole cover at specific locations and provide the mounting surfaces for fixtures. This segmentation simplifies the pole cover design to a basic extruded aluminum structure without T-shaped slots, while the support poles carry the mounting functionality.
Solution Approach 2:
The support pole acts as an intermediary component between the pole cover and the mounting fixtures. Instead of directly forming T-shaped slots in the pole cover, the support pole serves as a mediator that provides attachment holes for fixtures while being detachably connected to the pole cover. This intermediary approach simplifies the pole cover structure while maintaining fixture mounting capability.

AI summary
The present invention includes: a pair of columnar members 12a and 12b disposed on both sides of a specimen SP; a crosshead 15, constructed so as to bridge the pair of columnar members 12a and 12b, that applies a load to the specimen SP by moving in a direction of a longitudinal axis of the columnar members 12a and 12b; and a support pole 35 at which a mounting fixture is to be attached, that extends in the direction of the longitudinal axis circumjacent the pair of columnar members 12a and 12b. The support pole 35 is provided with a sliding attachment unit 35b to 35d that extends in the direction of the longitudinal axis and slides a mounting fixture for use in material testing to change a position at which the mounting fixture is attached.
