Bayonet Whirling Ring Connection for Rapid Machine Tool Replacement

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current thread whirling devices require time-consuming and costly procedures to replace the whirling ring, often necessitating removal of the entire device from the machine tool, leading to inefficient capacity utilization due to restrictive design and limited space.

Innovation Solution

A bayonet-type connection between the whirling ring and hollow spindle allows for rapid replacement without removing the device from the machine tool, utilizing a form-locking fit and clamping bolts for secure torque transmission, along with a tool for precise insertion and removal, enabling easy access and minimal space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the whirling ring is connected via flange connection and front-end bolts, then the connection is secure, but the replacement process becomes time-intensive and requires removing the entire device from the machine tool

Engineering Contradiction:

Improveconnection securityVSAvoidreplacement time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The connection between the whirling ring and hollow spindle is segmented into a modular bayonet-type connection system, allowing the whirling ring to be quickly detached and replaced without removing the entire device from the machine tool, thus reducing replacement time while maintaining connection security

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bayonet-type connection enables dynamic replacement of the whirling ring during operation, transforming the static replacement process into a quick, movable operation that can be performed without device removal, thereby reducing downtime

Inventive Principle:

Principle #15Dynamics

2Device complexity

If the whirling ring is accessible only from the processing side, then the design is simple, but the replacement requires removing the entire thread whirling device from the machine tool

Engineering Contradiction:

Improvedesign simplicityVSAvoidmachine tool capacity utilization

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The bayonet-type connection introduces a rotational dimension to the assembly process, allowing the whirling ring to be quickly inserted and locked into place through a twisting motion, enabling replacement without device removal and improving productivity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If the whirling ring replacement requires removing the entire device, then the connection is secure, but the space requirements and operational costs increase

Engineering Contradiction:

Improveconnection securityVSAvoidspace requirements

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The connection system is segmented into a compact bayonet-type interface that maintains secure connection while minimizing the space required for replacement operations, allowing the whirling ring to be changed in-place without requiring device removal and reducing operational space requirements

Inventive Principle:

Principle #1Segmentation
