Problems solved by technology

In the process of utilizing wind energy, the wind generator is one of the most important equipment; in order to obtain enough wind energy, the wind generator is usually bulky, so its assembly is extremely cumbersome and complicated. Operations such as dipping paint are often complicated to process; during the assembly process of the stator of an ordinary wind turbine, large-scale CNC machine tools are required for precise slotting before the bead can be accurately installed to form the stator tooth pressure plate, so the assembly is not only expensive, but also time-consuming and laborious. The efficiency is low; and the lamination coefficient is too low in the lamination process of the core punching sheets, resulting in low quality of the entire stator and a decrease in the yield rate

Embodiment Construction

[0038] see Figure 1~6 , a kind of 3MW permanent magnet synchronous wind generator stator core assembly process that the present invention relates to, it is characterized in that: described process comprises the following steps:

[0039] Step A: Assembly of the stator tooth pressure plate;

[0040] A1: Place the ring-shaped pressing plate 1.1 horizontally on the worktable, and press-fit the fan-shaped welding die 1.2 on the ring-shaped pressing plate 1.1. Both the ring-shaped pressing plate 1.1 and the fan-shaped welding die 1.2 have mark ports and pin holes. The ring-shaped pressing plate 1.1 Align with the fan-shaped welding mold 1.2 through the mark opening, and insert the positioning pins to fix after aligning the pin holes. The fan-shaped welding mold 1.2 is pre-evenly provided with a plurality of indexing grooves for placing the bead 1.3;

[0041] A2: Put the bead 1.3 into the groove pre-opened on the fan-shaped welding mold 1.2, the bottom surface of the bead 1...

Description

technical field [0001] The invention relates to an assembly process, in particular to an assembly process for a stator core of a 3MW permanent magnet synchronous wind power generator. Background technique [0002] With the increasingly serious energy crisis, the development of new energy sources has attracted widespread attention. Among them, wind energy has been widely used because of its simple acquisition and abundant stock. In the process of utilizing wind energy, the wind generator is one of the most important equipment; in order to obtain enough wind energy, the wind generator is usually bulky, so its assembly is extremely cumbersome and complicated. Operations such as dipping paint are often complicated to process; during the assembly process of the stator of an ordinary wind turbine, a large CNC machine tool is required to perform precise slotting before the bead can be accurately installed to form the stator tooth pressure plate, so the assembly is not only expensiv...
