Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blade assembling methods for torque converters require complex mechanisms to press blades against the shell, making the process cumbersome and difficult to execute efficiently.
Innovation Solution
A blade assembling method involving a blade holding mechanism that allows for initial fitting of at least one claw into a corresponding groove, followed by relative movement to guide and insert the remaining claws into their respective grooves, using a robot to automate the process and ensure smooth assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressing pusher is used to downwardly press the blade against the shell while supporting both blade surfaces, then all claws can be inserted into grooves, but the mechanism becomes complicated and difficult to operate
Solution Approach 1:
The patent removes the pressing pusher component from the assembly mechanism. Instead of using a complex pressing mechanism to force claws into grooves, the invention relies on the elastic deformation of the blade body during relative movement to automatically insert claws into corresponding grooves, thereby simplifying the device structure while maintaining reliable insertion
Solution Approach 2:
The blade's own elastic deformation during relative movement between the blade and shell serves the function of inserting claws into grooves. The blade structure itself provides the insertion force through its elasticity, eliminating the need for external pressing mechanisms and achieving self-service insertion
2Manufacturing precision
If a pressing pusher is used to support both blade surfaces during insertion, then precise positioning is achieved, but the ease of operation is reduced
Solution Approach 1:
The pressing pusher is removed from the system, eliminating the complexity of supporting both blade surfaces during insertion. The invention achieves precise positioning through the controlled relative movement between blade and shell, where the blade's elastic deformation naturally guides the claws into correct positions without requiring additional support mechanisms
Solution Approach 2:
The invention utilizes dynamic relative movement between the blade and shell during assembly, allowing the blade to elastically deform and flexibly adapt to positioning requirements. This dynamic approach replaces the static support of both surfaces by rigid pushers, improving ease of operation while maintaining precision through the blade's inherent elastic properties

AI summary
Provided is a blade assembling method for a converter, wherein a blade 20 held by blade holding means (adsorption part 152) is further relatively moved with respect to a shell 10, whereby, while remaining claws 21B and 21C of the blade 20 are pressed against the upper surface of the shell 10 in an obliquely forward and downward direction by the holding force of the blade holding means (adsorption part 152), the claws 21B and 21C are slid toward grooves 11B and 11C from the near side of the corresponding grooves 11B and 11C and inserted so as to fall in the grooves 11B and 11C to thereby insert all the claws 21A to 21C into all the corresponding grooves 11A to 11C, respectively.
