Automatic welding machine for flat steel plates

Abstract

The invention discloses an automatic welding machine for flat steel plates, and belongs to the technical field of welding equipment. The automatic welding machine comprises a bottom plate, a steel plate fixing device, a steel plate lifting device, a moving device, a welding device, a welding auxiliary device and two steel plate clamping device, wherein the steel plate fixing device is arranged atthe top of the bottom plate, the two steel plate clamping devices are symmetrically arranged on the steel plate fixing device, a moving rack which is vertically arranged is arranged on the bottom plate, the moving device is arranged on the moving rack, the welding device comprises an upper welding assembly and a lower welding assembly, the upper welding assembly is arranged on the moving device, the lower welding assembly is arranged on the bottom plate, the welding auxiliary device is arranged on the upper welding assembly, and the steel plate lifting device is arranged on the steel plate fixing device. According to the automatic welding machine, two clamping and fixing plates rotate to fix the steel plates on fixed slide blocks, so that the condition that accuracy of welding between thetwo steel plates is affected by position deviation of the two steel plates during welding of the steel plates is avoided.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to an automatic welding machine for flat steel plates. Background technique [0002] Welding machines are actually transformers with reduced external characteristics, which convert 220V and 380V AC into low-voltage direct current. Generally, electric welding machines can be divided into two types according to the type of output power supply, one is AC power supply; the other is DC power supply. When the output terminal is switched on and off, a huge voltage change will occur. When the two poles are short-circuited instantaneously, the arc will be ignited, and the generated arc will be used to melt the welding rod and welding material, and then the purpose of combining them will be achieved after cooling. The welding transformer has its own characteristics, the external characteristic is the characteristic that the voltage drops sharply after the welding rod is ignited. Au...
