Automatic welding machine

Abstract

The invention discloses an automatic welding machine, and belongs to the technical field of automatic welding. The automatic welding machine solves the technical problems that the labor intensity of workers is high and the production efficiency is low in the prior art. The automatic welding machine comprises a welding device and a working table provided with a rotary disc, and a plurality of fixtures for clamping workpieces are arranged on the rotary disc circumferentially at intervals; welding stations are arranged on the working table; and the automatic welding machine further comprises a first wire feeding mechanism and a scaling powder brushing mechanism which are arranged on the welding stations, the first wire feeding mechanism conveys welding wires to a workpiece which rotates to the fixture of the corresponding welding station, and the scaling powder brushing mechanism is used for brushing a scaling powder on the welding wires conveyed by the first wire feeding mechanism.

Description

【Technical field】 [0001] The invention relates to the technical field of automatic welding, in particular to an automatic welding machine for four-way valve pilot valve welding. 【Background technique】 [0002] The Chinese invention patent with the publication number 105458443 A disclosed a rotary disc type four-way valve automatic flame brazing machine on April 6, 2016, including a working platform, a brazing fixture table, an automatic wire feeding controller, and a brazing automatic brazing machine. Heater, electric control box, intelligent gas control box and brazing fixture, described brazing fixture workbench is installed on the described working platform, described brazing fixture workbench is provided with workpiece detection sensor, and described automatic wire feeding The controller and the brazing automatic heater are installed on the table of the work platform and placed around the workbench of the brazing fixture. The electrical control box and the intelligent ga...

Problems solved by technology

From the above welding process, we can know figure 1 The automatic welding machine has the following deficiencies when welding the pilot valve 4: (1) The welding working environment is poor, and the gas and smoke generated by the flux heating are harmful to the body. It is easy to cause heatstroke of the welder; (2) The labor intensity is high, the welder needs to brush the flux and send the welding wire for the D capillary 43, and send the welding wire for the ESC capillary and the valve seat 42 and move, and work with both hands and the arm is suspended, which is easy to fatigue; (3) low production efficiency
