Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece conveying apparatuses face challenges in achieving high-speed conveyance due to backlash and vibration caused by gaps between the engagement lever and annular groove in the mounting and dismounting mechanism, which also complicates the replacement process.
Innovation Solution
A mounting and dismounting support mechanism that includes a movable member with a linear drive mechanism, coupling shafts, and turnable coupling members, allowing for precise positioning and locking of the workpiece holding device on the conveying apparatus without free movement, thereby eliminating backlash.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an engagement lever is used to engage with an annular groove for mounting and dismounting, then the workpiece holding device can be freely removed and installed, but backlash and vibration occur due to gaps between the engagement lever and annular groove
Solution Approach 1:
The engagement mechanism is divided into two separate functional components: a positioning mechanism that ensures precise alignment between the workpiece holding device and conveying apparatus, and a locking mechanism that secures the connection. This segmentation allows each component to perform its specific function optimally without the drawbacks of the integrated engagement lever-annular groove design.
Solution Approach 2:
A positioning mechanism acts as an intermediary between the workpiece holding device and the conveying apparatus. This intermediary component facilitates precise alignment and connection during the mounting process, ensuring that the locking mechanism can engage properly without backlash or vibration issues.
2Reliability
If the annular groove is positioned precisely for engagement, then reliable connection is achieved, but replacement becomes complicated when position adjustment is needed
Solution Approach 1:
The positioning mechanism incorporates adjustable elements that allow the position to be dynamically changed during the replacement process. This enables the system to adapt to different workpiece holding device specifications while maintaining reliable engagement, eliminating the need for fixed, pre-positioned annular grooves.
3Adaptability or versatility
If manual positioning is used during replacement, then adaptability to different specifications is achieved, but operation time increases
Solution Approach 1:
The positioning mechanism is designed with pre-configured adjustment features and guide elements that automatically align the workpiece holding device with the conveying apparatus during replacement. This preliminary preparation of the positioning system eliminates the need for time-consuming manual positioning operations while maintaining adaptability to different specifications.
