Description

Technical Field

[0001] The present invention relates to the technical field of wind power casting polishing, and more specifically, to a surface polishing device for wind power castings and its usage method. Background Art

[0002] Wind power castings refer to the cast parts used in wind turbine generators, mainly used to support and connect various components of the wind turbine. They need to have excellent mechanical properties, corrosion resistance, wear resistance, and fatigue resistance to cope with various challenges that may occur during the long-term operation of the wind turbine. They mainly include accessories such as nacelle housings, gearbox housings, bearing seats, and flanges. The polished surface can reduce friction and extend the service life. Moreover, if there are oxide layers or uneven places on the surface of the castings, problems are likely to occur in humid and corrosive environments. The polished surface helps to remove these unevennesses and improve the corrosion resistance of the castings.

[0003] Among them, when polishing wind power flange castings, due to the presence of flanges on the flange surface, the surface is not flat. Therefore, manual polishing is generally used, resulting in low polishing efficiency. Summary of the Invention

Subsequently, the fourth motor drives the bearing platform and the flange casting to rotate, and synchronous polishing of the side flange and the inner ring of the flange casting can be achieved, improving the polishing efficiency.

[0016] 2. By setting up a clamping mechanism, the second gear drives the third lead screw to rotate, driving the two side arms to move closer, driving the positioning frame to move towards the side wall of the flange casting, and clamping the flange casting by abutting against it with the abutting rollers.

[0032] Specifically, the working principle of this surface polishing device for wind power castings is as follows: During use, the flange casting to be polished is placed on the placement seat 3. The third motor 414 drives the moving seat 2 to move towards the bracket 401. The first toothed plate 415 can drive the first gear 416 to drive the first lead screw 403 to rotate, thereby driving the first threaded block 402 to move downward, driving the first polishing block 405 to contact the side wall flange of the flange casting, and driving the first polishing block 405 to rotate through the first motor 404 to polish the side wall flange of the flange casting. At the same time, the lifting plate 406 can be driven to descend through the electric telescopic rod 407, so that the second polishing block 411 extends into the inner wall of the flange casting, and the second polishing block 411 is driven to rotate through the second motor 408 to polish the inner ring of the flange casting. Subsequently, the fourth motor 418 drives the carrier table 417 and the flange casting to rotate, and synchronous polishing of the side wall flange and the inner ring of the flange casting can be achieved, improving the polishing efficiency.

[0033] When the third motor 414 drives the moving seat 2 to move towards the bracket 401, the second gear 506 meshes with the second toothed plate 507, thereby driving the third lead screw 505 to rotate through the second gear 506, driving the two side arms 501 to move closer, driving the positioning frame 502 to move towards the side wall of the flange casting, and clamping the flange casting through the abutting roller 503. At the same time, the electromagnetic coil 511 is energized to adsorb the flange casting on the surface of the carrier table 417. Subsequently, the fourth motor 418 drives the carrier table 417 and the flange casting to rotate, driving the abutting roller 503 to rotate, and thereby driving the polishing roller 508 to rotate in the reverse direction through the third gear 509 and the fourth gear 510 to synchronously polish the outer ring of the flange casting.

[0034] When the fourth motor 418 drives the carrier table 417 and the flange casting to rotate, the convex block 608 is driven to rotate synchronously, thereby squeezing the contact plate 606, and under the action of the first spring 607, driving the arc piston 604 to reciprocate in the air injection cavity 603, injecting air into the cavity 601, and spraying it onto the surface of the flange casting through the spray holes 602 to dissipate heat from it and ensure the polishing quality.

At the same time, the electromagnetic coil 511 is energized to adsorb the flange casting on the surface of the carrier table 417. S2: Polishing; The first toothed plate 415 drives the first gear 416 to drive the first lead screw 403 to rotate, thereby driving the first threaded block 402 to move downward, driving the first polishing block 405 to contact the side wall flange of the flange casting, and polishing the side wall flange of the flange casting. At the same time, the lifting plate 406 can be driven to descend through the electric telescopic rod 407, so that the second polishing block 411 extends into the inner wall of the flange casting to polish the inner ring of the flange casting. Subsequently, the fourth motor 418 drives the carrier table 417 and the flange casting to rotate, driving the abutting roller 503 to rotate, so as to drive the polishing roller 508 to rotate in the reverse direction through the third gear 509 and the fourth gear 510 to polish the outer ring of the flange casting synchronously.
