Multi-piece motor core one-time lamination welding system and method

Abstract

The invention discloses a system and method for one-time overlaying welding of multiple motor iron cores, and belongs to the field of motor manufacturing. Multiple motor stator or rotor sheets are overlaid and placed on an overlaying mechanism. Positioning gaps are formed in the sheets. The overlaying mechanism comprises a sheet positioning device arranged on a table face, an overlaying device arranged on the upper portion and a counter arranged on the side face. A pressure head is arranged on the overlaying device. The two ends of the overlaid sheets are provided with a plurality of welding guns and electrode contact positions. A sheet carrying-in device and an iron core carrying-out device are arranged nearby the overlaying mechanism. An overlaying welding system is connected with a controller. By means of a high-voltage electric arc welder, multiple sheets can be welded at a time, the welding speed can be increased, the sheet overlaying work procedure is simplified, the production efficiency is improved, and product quality is ensured.

Description

technical field [0001] The invention relates to a welding method, in particular to a one-time lamination welding system and method for multi-piece motor iron cores, belonging to the field of motor manufacturing. Background technique [0002] The motor consists of two parts, the rotor and the stator, which are used to realize the conversion of electrical energy and mechanical energy. Iron cores are generally made of soft magnetic materials. The varieties of soft magnetic materials include ordinary carbon structural steel, silicon steel sheet, electrical pure iron and magnetic permeable alloy. In addition to the pole cores of DC motors and synchronous motors, which are usually made of ordinary carbon structural steel plates, the most commonly used material for punching motor cores is silicon steel sheets. Some motors also use electrical pure iron or magnetically permeable alloys (such as iron-nickel alloys, iron Pot table gold, etc.). [0003] In the prior art, the iron cor...
