Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness production, and more specifically, to an online welding auxiliary device for automobile wiring harnesses. Background Art

[0002] The automotive wiring harness is the network body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to a component that is formed by crimping the contact terminals made of copper materials with the wires and cables, and then plastic-pressing the insulators or adding metal shells on the outside to form a wiring harness to connect the circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. Wire harnesses are widely used and can be used in automobiles, home appliances, computers and communications equipment, various electronic instruments and meters, etc. In the process of processing automotive wiring harnesses, it is sometimes necessary to weld the wires of two wiring harnesses. Generally, ultrasonic metal welding machines are used for welding. However, when using ultrasonic metal welding machines for welding, manual labor is required to hold the two wires for welding. There are certain risks in the welding process, and it also affects its work efficiency. For this reason, we have proposed an online welding auxiliary device for automotive wiring harnesses.

[0027] In this embodiment, the second electric push rod 14 is used to drive the support plate 15 to move up and down, and the support plate 15 is used to support wire harnesses of different outer diameters, so that the wire harness welding ends on the two rotating seats 8 can contact each other.
