Problems solved by technology

[0002] In the existing technology, the axial and radial dimensions of offshore wind power products are very large, and they are generally processed and produced in segments, and finally the stators of each segment are spliced ​​into a whole. It is formed by press-fitting, the mold investment cost is high, the production management cost is high, and the splicing process is unstable. The iron core needs to be drilled on the surface to assemble, and the processing cost is high. It is not conducive to fixing the assembly casing in the subsequent process. Provide customers with good quality products

Abstract

The invention discloses a wind generator stator core pressing device which comprises an internal pressing cover plate, an internal pressing side plate, a pressing base, external pressing end plates, top slide blocks, disc springs, a side slide block, closed punching sheets, screw rods and screws. The external pressing end plates abut against the sides of the closed punching sheets. The internal pressing cover plate abuts against the upper surfaces of the closed punching sheets. The internal pressing cover plate and the closed punching sheets are locked by the screw rods. The side slide block is arranged on the right side of the closed punching sheets. The top slide blocks are arranged on the left side of the closed punching sheets. The pressing side plate and the pressing base are locked and fixed by the screws. The external pressing end plates are locked by the screw rods, and the screw rods are sleeved with the springs. The wind generator stator core pressing device has the advantages of gapless pressing between cores, convenient assembly and low cost.

Description

technical field [0001] The invention relates to the press-fitting of the stator core of a block-type wind power generator, and belongs to the field of wind power generator manufacturing. Background technique [0002] In the existing technology, the axial and radial dimensions of offshore wind power products are very large, and they are generally processed and produced in segments, and finally the stators of each segment are spliced ​​into a whole. It is formed by press-fitting, the mold investment cost is high, the production management cost is high, and the splicing process is unstable. The iron core needs to be drilled on the surface to assemble, and the processing cost is high. It is not conducive to fixing the assembly casing in the subsequent process. To provide customers with good quality products. Contents of the invention [0003] The invention aims at the deficiency of the prior art, and aims to provide a press-fitting device for stator cores of wind power genera...
