Rotation type welding device for silicon steel sheet

Abstract

The invention discloses a rotation type welding device for a silicon steel sheet. The rotation type welding device comprises a welding working table provided with a silicon steel sheet positioning tool, and is characterized in that the welding working table is provided with a lifting mechanism and a rotation type welding gun mechanism driven by the lifting mechanism to lift; the rotation type welding gun mechanism comprises a lifting plate, an annular core shaft fixed to the lifting plate in the longitudinal direction and a welding gun positioning ring installed on the annular core shaft through a bearing in a sleeving manner; the rotation type welding device further comprises a driving motor which is arranged on the lifting plate, is connected with the welding gun positioning ring through a transmission mechanism, and drives the welding gun positioning ring to rotate; and an opening for the silicon steel sheet to penetrate is formed in the position, on the inner side of the annular core shaft, of the lifting plate, and at least one welding gun is fixed to the welding gun positioning ring along the periphery. By means of the device, manual work can be replaced for conducting inclined welding operation on the silicon steel sheet, the automatic degree is high, and the operation efficiency and the product quality can be greatly improved.

Description

technical field [0001] The invention relates to a silicon steel sheet rotary welding device. Background technique [0002] In order to reduce the hysteresis loss and eddy current loss of the motor in the known technology, and prevent overheating during operation to reduce performance or even burn out, the stator core of the motor is usually made of silicon steel laminations and then welded and fixed. [0003] In conventional technology, when welding and producing the above-mentioned silicon steel sheet stator, the welding torch is usually set on the vertical guide bar and welded along the vertical line. The solder joints on the upper and lower silicon steel sheets are all on the same vertical line, and the welding lines are straight. However, the silicon steel sheet stator with linear welding pattern will cause the following effects in actual operation: due to the magnetic loss of the silicon steel sheet at the welding point, the magnetic field is weaker than other areas, re...

Problems solved by technology

[0005] However, in the prior art, the oblique welding of silicon steel sheets is mostly performed manually, lacking reliable and convenient automation equipment. Because it is difficult to control the welding trajectory manually, the operation of this process is difficult and labor-intensive, which greatly affects the working efficiency and ultimately The quality of welding products is not high
