Embodiment Construction

[0009] The three-station automatic argon arc welding machine of the equipment in the present invention consists of: two lamination stations (1) (3) and one press-fit automatic welding station (2), two lamination stations (1) ) (3) each has a set of press-fit tires (4) and positioning and tensioning oil cylinders (5), the slope function is realized by a set of automatic swing mechanism (6), and the slope can be adjusted according to technological requirements; the present invention The production method is as follows: install the mold (4) on the positioning cylinder (5) and check the quality of the mold → weigh the sleeve and tighten it, place the flange (7) on it and press it → remove the stator core from the stack The sheet station (1) moves to the welding lamination station (2) and presses it down → put the welding torch fixing ring on the lower arc starting position → adjust the distance of the welding torch, start the welding process, and start welding work → tighten the ex...

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 ...
