The present invention is achieved through the following technical solutions:
The lightweight full-laminated motor support that cast welding combines, comprises iron-core lamination, arm-tie, mount pad, pressing plate and end plate; Wherein, the main body of electric machine stand applies certain pressure that laminates by the iron-core lamination forming motor stator magnetic circuit and is neatly overrided to form, the two ends of iron-core lamination are respectively equipped with an end plate, the outside of each end plate is provided with a pressing plate, overlapped together by folded pressure thight under packing state between iron-core lamination, end plate and pressing plate, end plate forms the yoke portion with the iron-core lamination of some (or length) and the teeth portion compression of electric machine stator iron together with pressing plate; Two arm-ties are close to the outer circular top part both sides of iron-core lamination as welding entity and are arranged, and after each arm-tie runs through iron-core lamination length, its two ends are overlapped on the pressing plate at two ends respectively, finally in the welding of arm-tie border; Two mount pads are close to iron-core lamination cylindrical two bottom sides as welding entity and are arranged, and after each mount pad runs through iron-core lamination length, its two ends are overlapped on the pressing plate at two ends respectively, finally in the welding of mount pad border; Arm-tie and mount pad should carry out processing with iron-core lamination binding face process, with ensure its when welding and iron-core lamination intimate surface fit; During welding, need to complete under packing state, need after welding to carry out destressing operation by the such as technique such as oscillating aging, ball blast, annealing, finally make the one that whole electric machine stand becomes firm.
Further, mount pad adopts to weld the cast structure of cast steel material casting, ensures its cast inside quality, avoid the weld defect of existing welding assembly by nondestructive flaw detection examination and casting technique, as: rosin joint, fillet welding such as not to fill at the problem; Eliminated stress by the curving of castings and certain Technology for Heating Processing, improve mechanical performance and the reliability of parts, its consistency is good, production efficiency is high, structural strength is reliable, solves the problem that the mount pad of existing full lamination welding frame and hanging place welding quality are difficult to ensure, welding job amount is large, productivity ratio is low.
End plate is provided with the profile of tooth corresponding with iron-core lamination, on end plate, the size of profile of tooth is less than the size of profile of tooth on iron-core lamination, enters operation to avoid the down of interfering motor winding; End plate is made by the steel plate with structural strength or is welded into entirety with several pieces sheet metals and forms, and the thickness of end plate is 4-8mm.
The internal diameter of pressing plate is greater than the bottom land size of iron-core lamination profile of tooth, enters operation to avoid the down of interfering stator winding.
Electric machine stand design science of the present invention, structure is simple, it is creationary together with by casting and welding, two kinds of special process modes combine, improve mechanical performance and the reliability of parts, its consistency is good, production efficiency is high, and structural strength is reliable, solves the problem that the mount pad of existing full lamination welding frame and hanging place welding quality are difficult to ensure, welding job amount is large, productivity ratio is low.
