Angled Wire Hose Connector for Arc Welding Robot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional arc welding robots with wire feeders at the rear of the forearm face challenges in reducing the rearward protrusion of the welding wire hose, leading to potential interference with surrounding objects and increased installation space requirements.
Innovation Solution
A welding wire processing structure that includes a wire hose connected to the rear end surface of the wire feeder at an angle intersecting the feed direction, using a connector to attach the hose obliquely, reducing rearward protrusion and allowing for flexible routing to avoid interference with surrounding objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wire hose is connected to the rear end surface of the wire feeder in the feed direction of the welding wire, then the structure is simple and easy to manufacture, but the wire hose protrudes rearward and may interfere with surrounding objects
Solution Approach 1:
The connector connects the wire hose to the rear end surface of the wire feeder in a direction intersecting the feed direction of the welding wire, changing the connection dimension from longitudinal to oblique/transverse. This dimensional change allows the wire hose to be routed away from the rearward space, eliminating interference with surrounding objects while maintaining manufacturing simplicity.
2Device complexity
If the wire hose is connected to the rear end surface of the wire feeder in the feed direction of the welding wire, then the structure is simple, but the installation space required is increased
Solution Approach 1:
By connecting the wire hose in a direction intersecting the feed direction rather than parallel to it, the wire hose is routed in a different spatial dimension. This reduces the rearward protrusion volume and optimizes the installation space footprint of the welding robot system.
3Object-affected harmful factors
If the wire hose is connected obliquely to the rear end surface of the wire feeder, then the rearward protrusion is reduced and interference with surrounding objects is minimized, but the connector structure becomes more complex
Solution Approach 1:
The connector serves as an intermediary component that interfaces between the wire hose and the wire feeder. It provides the oblique connection function while maintaining a relatively simple structure through features such as a connection body with an inlet and outlet, and a fixing mechanism that secures the wire hose at the optimized angle.
