Multi-axis automatic welding device

Abstract

The invention discloses a multi-axis automatic welding device which comprises a support base, a transverse transmission device, longitudinal transmission devices and vertical transmission devices. The transverse transmission device is perpendicular to the longitudinal transmission devices, and the vertical transmission devices are perpendicular to the transverse transmission device and the longitudinal transmission devices. The transverse transmission device, the longitudinal transmission devices and the vertical transmission devices are all connected with a driving device. A transformer is arranged on the transverse transmission device, each vertical transmission device is provided with soldering pliers, and the soldering pliers are connected with the transformer which is located between the longitudinal transmission devices. The vertical transmission devices are connected with the corresponding longitudinal transmission devices in a sliding mode, and the longitudinal transmission devices are connected with the transverse transmission device in a sliding mode. The multi-axis automatic welding device is simple in structure, the positions of the soldering pliers can be changed left and right in the transverse direction, changed front and back in the longitudinal direction and changed up and down in the vertical direction, the multi-axis automatic welding device is more flexible to use, the layout is optimized, current loss is small, energy is saved, the welding spot quality is effectively improved, the operation failure rate is low, the service lives of the soldering pliers and the transformer can be effectively prolonged, and welding efficiency is high.

Description

technical field [0001] The invention relates to a welding device, in particular to a multi-axis automatic welding device used in the automobile manufacturing industry. Background technique [0002] When dealing with the welding joints where the side apron edge and the lower body meet, the automobile assembly and welding line generally adopts two methods: manual welding and automatic welding. With the increasing labor productivity of modern factories and the increasing emphasis on labor protection and ergonomics, traditional manual welding methods are gradually replaced by mechanized automatic welding mechanisms. In the middle, different welding methods such as fixed single-point automatic welding and sliding multi-point automatic welding have appeared in the automatic welding mechanism of automobile skirt. At present, the sliding multi-point automatic welding is most commonly used in the skirt welding area. Its advantage is that a single device can achieve more welding poin...

Problems solved by technology

But this sliding automatic welding mechanism also has the second serious defect of the structure, that is, the transformer 2 is fixed on the base plate, and the connecting copper plate 3 needs to be drawn out from the transformer 2, then to the area near the welding tongs 5, and then through the soft Cable 4 connects copper plate 3 and welding clamp 5

[0004] Disadvantages of this design: firstly, the automatic welding that moves in a single direction can only be used for simple solder joints, and cannot weld solder joints that are not in a straight line; secondly, it is impossible to realize flexible switching of multiple models
