Problems solved by technology

Because a certain positional relationship is formed between the rotor shaft part, the iron core part, and the magnetic steel after die-casting, it is very difficult to assemble the iron core, magnetic steel, and the position of the rotor shaft before aluminum casting. This rotor belongs to a new rotor. structure, there is no domestic production, so there is no mature assembly method

Embodiment Construction

[0015] As shown in the figure, the assembly method of the cast aluminum rotor assembly with built-in magnetic steel includes the following steps:

[0016] 1. Prepare the iron chip: Use a mold to punch the iron chip. The outer circle of the iron chip has a margin of not less than 0.5 mm. The bottom is provided with an inward arc 3 in the middle, and grooves are provided at both ends of the bottom. , two symmetrical process holes 2 are also arranged on the iron chip, and the process holes 2 communicate with the outside through the bottom of the iron chip;

[0017] 2. Riveting the iron chips: the punched iron chips are riveted into iron core parts 1 by riveting screws, and a total of two iron core parts 1 are riveted;

[0018] 3. Assemble the rotor shaft parts: symmetrically set deep holes on the position where the iron core parts are installed on the rotor shaft 4, install two positioning pins 5 on the holes to form the rotor shaft parts, and these two positioning pins 5 ensure ...

Abstract

The invention relates to an assembly method of a cast aluminum rotor assembly with built-in magnetic steel. The positioning of the rotor shaft is realized by setting a circular arc on the iron core, and a groove for pasting the magnetic steel is provided to position the magnetic steel; two process small holes The setting of , plays the role of limiting the angle of the iron chip. The invention can realize the formation of a certain positional relationship between the rotor shaft part, the iron core part and the magnetic steel after die-casting, and guarantee the use requirements of the rotor assembly.

Description

technical field [0001] The invention relates to an assembly method, which is an assembly method of a cast aluminum rotor assembly with built-in magnetic steel. Background technique [0002] At present, the cast aluminum rotors used in the ignition devices of domestic aircraft are mostly cage-shaped rotors, which are completed by casting aluminum. First punch the punched iron core, and then put the iron core punched on the dummy shaft sleeve, and lock the two ends with nuts. Aluminum alloys are cast into the slots of the core and the end rings at both ends of the core to make the rotor a solid unit. After the casting is completed, withdraw the process shaft sleeve, and then install the product shaft for processing. [0003] The cast aluminum rotor with built-in magnetic steel is the main component of a new type of inductive energy storage ignition device for aviation, mainly including the rotor shaft, positioning pins, magnetic steel, and rotor core, such as figure 1 shown...
