Embodiment Construction
[0017] The frame of a certain traction motor is a fully laminated welded iron core, and the core lamination adopts the motor core lamination tooling with inserts to adjust the diameter for lamination and welding. After the welding is completed, the core tire is loosened, and the iron core base is lifted out for the next process. At present, the structural tooling has been applied to the mass production of traction motors.
[0018] Such as figure 1 As shown, a motor core lamination tool for adjusting the diameter of inserts includes a horizontally arranged base 1, and a cross carcass 3 is fixed in the center of the base 1, and the center of the cross carcass 3 has a vertical through hole. Cylinder structure, the outer wall of the cylinder protrudes outward in four directions orthogonal to each other to form cross ribs; the outer sides of the adjacent pair of cross ribs are equipped with vertical strip-shaped fixing modules 2, and the other The outer surface of the adjacent cr...

The invention relates to a motor iron core lamination technology, in particular to a motor iron core lamination tool for adjusting the diameter of an insert. It solves the technical problem of difficulty in carcass processing and bodiless removal due to the fixed cylindrical carcass of traditional lamination tooling. A motor core lamination tool for inserting blocks to adjust the diameter, including a horizontal base, a cross carcass is fixed in the center of the horizontal base, the cross carcass is a cylinder structure with a vertical through hole in the center, and the outer wall of the cylinder is The four sides protrude outward in four directions orthogonal to each other to form cross ribs; the outer sides of the adjacent pair of cross ribs are equipped with vertical strip-shaped fixing modules, and the outer faces of the other pair of adjacent cross ribs are inward. The depression forms a groove, and a wedge is inlaid in the groove, and the outside of the wedge is equipped with a long strip-shaped movable module, and the movable module is positioned by the groove in the circumferential direction; a pair of cross ribs equipped with a wedge are equipped with shrinkage structures .
Description
technical field [0001] The invention relates to a motor iron core lamination technology, in particular to a motor iron core lamination tool for adjusting the diameter of an insert. Background technique [0002] For enterprises producing railway motors, generally speaking, a large number of traction motors are produced each year, involving different diameters and multiple varieties. Among them, the main motor stator core is a fully laminated welded core. It is characterized in that multiple hangers are welded on the iron core to form an integrated frame iron core, and the welding volume is very large. The shrinkage and deformation of the inner cavity of the iron core caused by large welding deformation can easily cause the inner cavity of the iron core to lock up with the carcass of the laminated tooling. In the light case, the tooth top of the iron core will be strained, and in the severe case, the entire iron core will be scrapped, causing quality loss to the enterprise. ...
