Suction Positioning Structure With Integrated Rod Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction positioning devices for machining have a complex configuration due to separate components for suction and positioning, which complicates the setup and operation.
Innovation Solution
A suction positioning device with an output rod, a sleeve with a tapered outer surface, and a transmission member with a tapered inner surface, where the sleeve is elastically deformed to position the output rod, allowing for simultaneous suction and positioning of workpieces without the need for separate suction and positioning pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate suction member and positioning pins are provided, then suction and positioning functions are achieved, but device complexity increases
Solution Approach 1:
The patent combines the suction member and positioning pins into a single integrated output rod structure. The output rod includes both the suction function (through air discharge passages) and positioning function (through positioning pins that protrude from the rod surface), eliminating the need for separate components and simplifying the overall device configuration while maintaining both functions
2Adaptability or versatility
If multiple separate components are used, then functional requirements are met, but number of moving parts increases
Solution Approach 1:
The output rod is designed as a multi-functional component that simultaneously performs suction (via air discharge passages), positioning (via integrated positioning pins), and support functions. This universal component replaces multiple specialized parts, reducing the total number of components while maintaining adaptability for handling various workpieces
