Automatic argon arc welding laminating apparatus and use method thereof

Abstract

The invention discloses an automatic argon arc welding laminating apparatus and a use method thereof. The automatic argon arc welding laminating apparatus consists of two lamination stations and one pressing automatic welding station. The production method comprises the steps: installing a die on a positioning oil cylinder and checking the quality of the die; weighing and expanding a nest plate; placing an upper pressing flange; shifting a stator iron core from a nest plate station to a welding state and tightly pressing the stator iron core; placing a fixed ring of a welding torch to an arc starting position at the lower end; adjusting the distance of the welding torch; starting the welding program; starting the welding operation; loosening the expanded oil cylinder after the welding is performed; loosening a main pressing oil cylinder; and shifting a workpiece to a second nest plate station and taking the stator iron core which is pressed and welded already. The apparatus can greatly improve pressing efficiency and quality of motor stator iron core. In addition, the contact area of a stator outer circle and a casing is more than that in buckling slab process by adopting the welding process, thereby the radiation of the motor is improved to enable the temperature of the motor to be reduced.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to production equipment for press-fitting stator cores of high-efficiency energy-saving motors and a production method using the equipment. Background technique [0002] At present, the stator cores of Y, Y2 and other series motors produced in my country are all press-fitted with clips, and dovetail grooves are designed on the stator punches to cooperate with the press-fitting. The mold structure for producing the punched punches is relatively complicated and difficult to process. During press-fitting, cracks are likely to occur at the dovetail groove, and large burrs are likely to occur on the punching sheet, which causes many quality defects in the pressing-fitting of the stator core; in addition, it is necessary to use buckles processed from 1-2 mm plates for lamination6 ~12 pieces, the elbows at both ends of the buckle are often deformed due to poor handling. In addition, the ...

[0002] At present, the stator cores of Y, Y2 and other series motors produced in my country are press-fitted with clips, and dovetail grooves are designed on the stator punches to cooperate with the press-fitting. The mold structure for producing the punched punches is relatively complicated and difficult to process.

During press-fitting, cracks are likely to occur at the dovetail groove, and large burrs are likely to occur on the punching sheet, which causes many quality defects in the pressing-fitting of the stator core; in addition, it is necessary to use buckles processed from 1-2 mm plates for lamination6 ~12 pieces, the elbows at both ends of the buckle are often deformed due to poor handling. In addition, the contact area between the outer circle of the stator and the casing using the buckle technology is small, which leads to a relatively high temperature rise of the motor during operation. Fast, high temperature rise
