Description

Technical Field

[0001] This utility model relates to the field of node assembly machine technology, and in particular to a welding positioning device for a node assembly machine with an adjustable function. Background Technology

[0002] A node pairing machine is a device or software system used to pair and connect different nodes in a distributed system or network. It is very important for building self-organizing, decentralized network systems, which can improve the resilience and efficiency of the network. When producing a node pairing machine, the position of the outer casing needs to be fixed first, and then some parts are welded onto the outer casing.

[0003] However, in existing equipment, the position of the outer shell cannot be flexibly adjusted after it is fixed. This means that when workers are welding parts in different positions, they have to repeatedly disassemble and reassemble the positioned outer shell, which is cumbersome and affects welding efficiency. Therefore, a node assembly welding positioning device with adjustable function is proposed. Utility Model Content
