Overlaying buckling sheet tooling

Abstract

The invention belongs to the technical field of stator overlaying. The overlaying buckling sheet tooling comprises a base and a core tyre; an annular base plate is fixed on the surface of the base; the core tyre is placed on the base plate; an axle hole is formed in the center of the base; the core tyre is formed by multiple detachable split cores in a spliced manner; an inner hole is formed in the core tyre; the inner hole is a taper hole that is gradually reduced from upper to lower; an expansion tyre is glidingly matched in the taper hole; an annular lower pressing ring is fixed on the surface of the base plate; the lower pressing ring is positioned on the periphery of the core tyre; a matched limiting structure is arranged on the surface, opposite to the split cores, of the inner circle of the lower pressing ring; the expansion tyre, the core tyre and the lower pressing ring are all concentric with the axial ole of the base; two opposite sliding grooves are formed in the base in a radial direction of the axle hole; clamping jaws are glidingly matched in the sliding grooves; the inserting ends, in the sliding grooves, of the clamping jaws are connected with the end parts of the sliding grooves through springs; and stop pins fixed with the base are arranged on the clamping jaws. The scheme of the overlaying buckling sheet tooling is high in universality, high in alignment precision and good in bending quality of the buckling sheet.

Description

technical field [0001] The invention belongs to the technical field of stator lamination. Background technique [0002] The stator core is an important part of the motor. Its main function is: when the motor is in the power generation state, the magnetic field lines generated by the rotor form a closed loop, and the electromagnetic wires wound in the slots of the stator core cut the magnetic field lines generated by the rotor. , so as to generate an induced current in the electromagnetic wire; when the motor is in the electric state, when the electromagnetic wire wound in the iron core slot is energized, the iron core slot is induced to attract and repel the magnetic pole and the rotor magnetic pole, pushing and pulling the rotor to rotate , so that the rotor shaft outputs power outward. [0003] The existing stator core is formed by stacking stator punches (usually silicon steel sheets). The existing punch lamination machine includes a centering shaft and an embedded rod. ...

Problems solved by technology

[0004] The disadvantage of this punch lamination machine is that the stator punch needs to use a special punch lamination machine according to the diameter of the shaft hole (the centering shaft of the professional punch lamination machine matches the stator punch shaft hole) ), the versatility is not strong, and the cost is high; on the other hand, because the diameter of the centering shaft is slightly smaller than the diameter of the shaft hole of the stator, it is easy to shift when several stator punches are stacked (that is, the axes of the stator punches cannot be aligned) ;Finally, the manual bending of the buckle is used, the production efficiency is low, the bending quality is low, and the buckle or stator punching is easy to be damaged when the hammering force is too large, resulting in waste products
