Cable End Holder with Offset Lever Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable end holding devices and assembly machines face challenges in efficiently positioning and securing cable ends at varying heights, leading to potential overstretching and errors during the crimping process, particularly with smaller cross-section cables, due to the need for manual adjustments and lack of independent height control.
Innovation Solution
A cable end holding device with a height position changing mechanism using two parallel and offset lever elements, allowing for independent height adjustment decoupled from the crimping process, enabling secure positioning and adaptation to different tools without requiring tool height changes, and incorporating a longitudinal position changing device to maintain precise vertical movement without longitudinal displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of plunger position is performed for each product, then the height position can be adapted to different crimping tools, but this results in setup errors and increased adjustment time
Solution Approach 1:
The system automatically determines the required height position based on product data and autonomously adjusts the plunger position without manual intervention. The control unit receives product information and automatically controls the height position changing device to position the cable end holding element at the correct height, eliminating manual setup errors.
Solution Approach 2:
The manual mechanical adjustment process is replaced by an automated control system that uses product data to automatically position the cable end holding element. The control unit processes product information and automatically actuates the height position changing device, replacing manual measurement and adjustment with automated digital control.
2Stability of the object's composition
If the cable end holding device is fixedly connected to the press, then stable positioning is achieved, but this prevents independent height adjustment during the crimping process
Solution Approach 1:
The cable end holding device is designed with dynamic height adjustment capability through the height position changing device. The plunger can independently change the height position of the cable end holding element during the crimping process, allowing the system to adapt to different product requirements while maintaining stable positioning through controlled movement rather than fixed connection.
3Reliability
If the cable end is positioned closer to the protruding parts of the contact, then clearance is sufficient, but this requires precise manual adjustment for each product variation
Solution Approach 1:
The control unit automatically determines the optimal position of the cable end relative to the protruding parts of the contact based on product data. The system self-adjusts the height position to ensure sufficient clearance without requiring manual calculation or adjustment, eliminating the complexity of manual positioning while maintaining reliable clearance.
4Productivity
If the punch and cable end move synchronously towards the anvil, then the crimping process is efficient, but this causes over-pressing and bending of smaller cross-section cables
Solution Approach 1:
The height position changing device enables dynamic adjustment of the cable end position during the crimping process. The plunger can independently control the vertical position of the cable end holding element, allowing the system to maintain synchronous movement efficiency while preventing over-pressing by dynamically adjusting the cable end position relative to the punch movement, especially protecting smaller cross-section cables.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for secure and precise positioning of cable ends at various heights, reducing setup time and preventing overstretching, as the lever elements maintain the adjusted height securely and allow for precise vertical movement without horizontal displacement, eliminating the need for a fixed connection to the press.
Implementation Method 1
a height position changing device with two lever elements for changing the height position of the cable holding element decoupled from a movement of a punch during the crimping process, wherein the lever elements are arranged parallel to each other along a longitudinal direction
