Tool applied to glue drying and curing of motor rotor

Abstract

The invention relates to a tool applied to glue drying and curing of a motor rotor. The tool comprises an upper tool die and a lower tool die. The tool upper die comprises an upper pressing plate andan annular lower pressing edge and is provided with a center hole, and upper screw holes evenly distributed along the circumference are formed in the upper pressing plate. The tool lower die is of a sleeve type structure with a bottom, an inner cavity of the tool lower die forms a positioning cavity allowing a rotor assembly to be inserted, and a protruding ring is arranged in the bottom of the tool lower die. A cross beam is arranged at the position, located on the inner side of the protruding ring, of the bottom of the tool lower die, two lower screw holes are formed in the cross beam, two semicircular open holes are symmetrically formed in the two sides of the cross beam, and a plurality of threaded holes which are evenly distributed along the circumference are formed in a barrel of thetool lower die; the upper tool die and the lower tool die are fixedly connected through a plurality of screws connected into the upper screw holes and the threaded holes in a one-to-one mode, the rotor assembly is pressed between the upper die and the lower die, and the lower tool die and the rotor shaft sleeve are fixedly connected through screws connected into the two lower screw holes and thetwo lower threaded holes in the rotor shaft sleeve. The tool can prevent the bidirectional movement of the rotor assembly, and achieves the wiping of the outflow adhesive with the tool.

Problems solved by technology

[0002] In the rotor assembly process of the finite-angle motor, the rotor sleeve is used as the basis, and the magnetic steel, filler block, rotor protective cover, and end cover are coated with glue, and then pressed into a whole by a press, and put into an oven for heating and curing. , but during baking and curing, the adhesive glue applied between the parts is easy to overflow and flow to the outer surface of the rotor assembly due to thermal expansion. And as a connection reference, once the adhesive glue flows to the surface of the rotor shaft sleeve, it will inevitably cause the motor and the shaft to be unable to cooperate precisely, and once the adhesive glue is cured, it is very difficult to clean up, and the relative position of the internal parts of the rotor assembly is prone to bidirectional damage when it is cured. In severe cases, the motor will be scrapped

[0003] At present, the widely used glue removal method is to take out the rotor after the glue has been cured for a period of time, wipe the adhesive glue flowing out of the outer surface, and then put it into the oven to continue heating, considering the pressing method and convenience of the motor rotor during the glue curing process. Wipe the adhesive glue flowing out during the curing process. The structure of the tooling used by domestic and foreign motor manufacturers in the process of curing the rotor glue is complicated. When curing the glue, the rotor needs to be removed from the tooling. The process is complicated and there is no protection against the rotor shaft. The measure of moving in two directions is not conducive to the application of engineering and mass production
