Multi-Axis Rotating Vehicle Part Test Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle part test devices have low mobility and limited test position flexibility, requiring the entire robot to be moved for position changes, which decreases work reliability and efficiency.
Innovation Solution
A vehicle part test device with rotatable operating portions connected to a robot, allowing for multi-directional movement and positioning through a system of motors, frames, and connection gears, enabling the test portion to accurately position and test vehicle parts by rotating around multiple axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire robot is driven to change the part test position, then the test position can be changed, but the mobility is low and work reliability is decreased
Solution Approach 1:
The test device is divided into three independently rotatable operating portions (first, second, and third operating portions), each capable of rotating around different axes. This segmentation allows the test portion to reach various test positions without moving the entire robot, thereby improving both test position flexibility and work reliability.
2Adaptability or versatility
If the entire robot is driven to change the part test position, then the test position can be changed, but the mobility is low
Solution Approach 1:
The test device is divided into three independently rotatable operating portions (first, second, and third operating portions), each capable of rotating around different axes. This segmentation allows the test portion to reach various test positions without moving the entire robot, thereby improving both test position flexibility and work reliability.
3Measurement precision
If the robot and test device are synchronized for position changes, then accurate positioning is achieved, but the complexity and time consumption increase
Solution Approach 1:
The test device incorporates three operating portions that can rotate independently around different axes (first operating portion around vertical axis, second operating portion around horizontal axis, third operating portion around vertical axis). This dynamic multi-axis rotation system allows the test portion to reach any position within its workspace without requiring synchronization with the robot, simplifying the control system while maintaining positioning accuracy.
