Automatic arc-voltage regulation device of automatic welder

Abstract

The invention relates to an automatic arc-voltage regulation device of an automatic welder, in particular to an automatic regulation device for automatically regulating arc voltage according to distance variation between a workpiece and a welding gun in the welding process of the automatic welder. The automatic arc-voltage regulation device comprises a voltage sensor used for detecting a voltage value when the welding gun carries out welding action, wherein the voltage sensor is connected with the input end of the controller; the output end of the controller is connected with a welding gun lifting driving motor used for driving the welding gun to lift; the controller stores the voltage value obtained when a voltage sensor detection welding gun welds on a reference position as a reference value; and when the voltage value detected by the voltage sensor is different from the reference value stored in the controller, the controller drives the welding gun to lift by the welding gun lifting driving motor until the voltage value obtained when the voltage sensor detection welding gun welds is consistent with the reference value stored in the controller. The automatic arc-voltage regulation device has simple structure, is convenient to install and use and is reliable and safe, distance between a workpiece and the welding gun is still kept consistent, and welding quality is improved.

Description

technical field [0001] The present invention relates to an automatic adjustment device, especially an automatic adjustment device for arc voltage of an automatic welding machine, specifically an automatic adjustment device that can automatically adjust the arc voltage according to the distance change between the workpiece and the welding torch during the welding process of the automatic welding machine , belongs to the technical field of automatic welding machines. Background technique [0002] At present, in the case of automatic welding, if TIG welding is used, in order to ensure the width of the weld, the depth of the weld, and the appearance of the shape, the distance between the welding torch and the workpiece must be kept constant during the welding process. However, due to the deformation of the workpiece and the unevenness of the working surface during the welding process, it is difficult to ensure that the distance between the workpiece and the welding torch is cons...
