Problems solved by technology

[0002] The use of wind power generation is very environmentally friendly, and the wind energy reserves are huge, so it is increasingly valued by countries all over the world; human beings rarely develop and utilize wind energy. Now the only wind power generator in the world is a three-leaf one-column. During its installation and use, the The wind source requirements of the environment are high. At the same time, this type of wind turbine has many restrictions on the size and huge investment, which also leads to the high cost of wind power generation.
The development trend of wind power generators is that the power is getting bigger and bigger, and the specifications and sizes are getting bigger and bigger accordingly. The machining of high-power wind power, such as the processing of wind power bases and wind power hubs, requires corresponding tooling and fixtures, and large-scale wind power bases processing, there is no corresponding tooling fixture and corresponding processing technology to ensure the stability and accuracy of processing

Embodiment 1

[0030] The present invention is a 4.0 megawatt wind power base blank processing technology, including the following process steps:

[0031] S1: Clean the surface of the workbench so that the roughness of the surface is below 0.2mm, hang the first-order tooling for wind power base blank processing on the workbench, and align the locking holes with the installation holes on the workbench, so that the first-order tooling and The sides of the workbench are parallel, and a sequence of tooling is locked, and the locking force of each locking point is ≥260KN;

[0032] S2: Adjust the screw on the vertical surface of the first-order tooling, so that the height difference between the left and right screws is less than 1mm, and the height difference between the upper and lower screws is about 136mm, so as to ensure the 5° inclination of the first-order tooling surface for processing with the wind power base; adjust The two screws on the transverse surface of the first-order tooling make ...

Embodiment 2

[0040] The difference from Embodiment 1 is that, as Figure 1 to Figure 6 shown (for ease of illustration, figure 1 The screw and the air charging and discharging port are not shown), the blank processing technology of the 4.0 MW wind power base includes the following process steps:

[0041] S1: Clean the surface of the workbench so that the roughness of the surface is above 0.2mm, hang the first-order tooling for wind power base blank processing on the workbench, and align the locking holes with the installation holes on the workbench, so that the first-order tooling Parallel to the edge of the workbench, lock a sequence of tooling, and the locking force of each locking point is ≥260KN;

[0042] S2: Use two 10m-long slings with a rated load of 15-20 tons to hoist the workpiece, and put the bottom surface of the workpiece against the vertical surface 1 of a sequence of tooling which is inclined to the vertical surface, and the side surface of the workpiece against On the hor...

Abstract

The invention discloses a 4.0 megawatt wind power base blank machining process. The 4.0 megawatt wind power base blank machining process comprises the following technical steps of S1, cleaning the surface of a workbench so that the roughness of the surface of the workbench is less than 0.2 mm; and locking a wind power base blank machining primary tool on the workbench; S2, adjusting threaded rodson the primary tool to guarantee the horizontal level of a workpiece; S3, using lifting strips to lift the workpiece; and after the workpiece is corrected, locking four press plates; S4, using a floor-type boring and milling machining center to perform fine milling, drill and tapping hole location machining according to a a counterbore hole, a pin hole and a threaded hole in the wind power base blank; S5, after primary machining is finished, unscrewing each threaded rod and the press plates; using the two lifting strips to lift the workpiece; using the two threaded rods to penetrate through primary holes with apertures of 38 mm to lock the workpiece; and then locking the press plates; and S6, according to the counterbore hole, the pin hole and the threaded hole in the wind power base blank, using the floor-type boring and milling machining center to perform fine milling, drill and tapping hole location machining. According to the 4.0 megawatt wind power base blank machining process, a4.0 megawatt wind power base can be machined through adoption of a reasonable design.
