Abstract

The invention discloses an automatic welding device and welding method for stators. The automatic welding device comprises a shell body, a base, a rotary table, a lifting mechanism, a compressing device, welding guns, an electrical cabinet, a guide rod, a hydraulic cylinder, a lead screw, a servo motor, dabber fixtures and a servo control system, wherein the rotary table is installed on the base through a rotary shaft, the lifting mechanism is installed in a rectangular tank of the base, the two dabber fixtures which are the same in structure are installed on the horizontal plane of the rotary table, and the welding guns are evenly distributed on the outer circumference of the compressing device. The rotary table is provided with the two dabber fixtures and has the work station rotating function, and two stators can be installed at the same time and then are welded and machined through rotation of the rotary table; meanwhile, the welding guns are installed at the same time, welding of multiple passes of welding lines can be conducted, and accordingly working efficiency is improved. A servo motor of the automatic welding device is controlled by the servo control system, and machining speed and position are accurate.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic stator welding device and a welding method thereof. Background technique [0002] As an important part of motors and compressors, stators have been produced for many years. An important part of its production process is to stack the stamped silicon steel sheets, fix them, and transfer them to the next process to roll off the coil. The traditional stator fixing method for small stators is bolt fixing or rivet fixing. It is necessary to punch out holes or slots for bolts and rivets in the stamping process, and then stack silicon steel sheets and penetrate bolts or rivets for fixing. This fixing method not only wastes the effective magnetic permeability area of ​​the silicon steel sheet and reduces the magnetic permeability, but also has low work efficiency in the lamination and fixing process. Contents of the invention [0003] In order to solve the above-mentione...
