Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative only and not limiting, and the scope of the present invention is not limited thereby.

The invention relates to a tool applied to drying and curing a motor rotor, which is shown in figures 1-3 and has the following invention points:

the tool comprises an upper tool die 2 and a lower tool die 4, wherein the upper tool die and the lower tool die are both made of stainless steel, preferably stainless steel 06Cr19Ni 10.

The upper die of the tooling comprises an upper pressing plate 2-2 and an annular lower pressing edge 2-3 which are arranged from top to bottom, the lower end of the annular lower pressing edge forms a pressing action surface which is contacted with the upper end face of a middle end cover of a rotor assembly, a central hole 2-4 is formed in the centers of the upper pressing plate and the annular lower pressing edge, an outer chamfering surface 2-5 is further arranged at the upper end of the central hole, on one hand, a glue wiping tool passes through the hole and extends into the tooling to wipe off the bonding glue flowing out of the upper end of the rotor assembly 3, and on the other hand, the weight of the upper die of the tooling is also. The periphery of the annular lower pressing edge on the upper pressing plate is provided with upper screw holes 2-1 which are uniformly distributed along the circumferential direction.

The lower tooling die is of a sleeve type structure with a bottom, a positioning cavity for inserting the rotor assembly is formed in an inner cavity of the lower tooling die, a raised ring 4-5 is arranged in the bottom of the lower tooling die, an upper supporting action surface which is contacted with the bottom of a rotor protection cover in the rotor assembly is formed at the upper end of the raised ring, and the distance between the upper supporting action surface and the upper end surface of the lower tooling die is smaller than the height of the rotor assembly; the bottom of the lower die of the tool is provided with a cross beam 4-4 on the inner side of the convex ring, the cross beam is provided with two lower screw holes 4-2, two semicircular openings 4-3 are symmetrically arranged on two sides of the cross beam, and the two semicircular openings have the following functions: the glue wiping tool passes through the glue wiping tool and stretches into the tool to wipe off the bonding glue flowing out of the lower end of the rotor assembly. A plurality of threaded holes 4-1 are uniformly distributed along the circumference on the cylinder body of the lower die of the tool.
