Problems solved by technology

Using such tooling improves the processing efficiency and labor intensity, but because the radial drilling machine needs to be installed on the radial outer periphery of the outer rotor, it not only takes up a lot of space, but also makes it difficult to process large-diameter outer rotors. In addition, There are also the defects of large number of equipment, complicated structure and high cost

Embodiment 1

[0079] see Figure 3 to Figure 21 , a method for combined processing threaded holes, comprising the following steps:

[0080] Step a, using a CNC gantry milling machine to process the positioning mother plate 1 and the positioning guide plate 8:

[0081] Both the positioning motherboard 1 and the positioning guide plate 8 are arc-shaped plates, and the outer arc surface of the positioning motherboard 1 and the outer arc surface of the positioning guide plate 8 are the same as the curvature of the inner arc surface of the outer rotor 2 of the permanent magnet generator. The same curvature here means that the outer arc surface of the positioning motherboard 1 and the outer arc surface of the positioning guide plate 8 have the same rotation radius corresponding to the inner arc surface of the outer rotor 2 of the permanent magnet generator, and they can be closely attached to each other after assembly. combine.

[0082] Since the outer arc surface of the positioning motherboard...

Embodiment 2

[0112] see Figure 12 and Figure 13 , the combined method of processing threaded holes in this embodiment, before step e, the circumferential positions of two adjacent positioning master plates are fine-tuned through the following steps:

[0113] de1. A positioning and measuring block 11 is respectively arranged on two adjacent positioning motherboards 1, and the two positioning and measuring blocks 11 are respectively pinned to adjacent two columns of guide holes 4 on two adjacent positioning motherboards 1, The opposite sides of the two positioning and measuring blocks 11 are all provided with reference planes 11a, and the size of the included angle α between each reference plane 11a and the radial plane of a row of guide holes 4 pinned to the positioning and measuring blocks 11 is equal to that of two adjacent half of the central angle β between two adjacent rows of guide holes 4 on the positioning motherboard 1;

[0114] In this embodiment, the central angle between the...

Embodiment 3

[0119] See 14 to Figure 17 , in the method for combined processing threaded hole of present embodiment, described step f specifically comprises the following steps:

[0120] f1, remove the two adjacent positioning motherboards 1 described in step c;

[0121] f2, such as Figure 14 As shown, a row of guide holes 4 on the edge of the positioning motherboard 1 removed in step f1 moves 13.5° in the circumferential direction, and is positioned by pins based on the processed magnetic steel threaded hole 2c, as shown in Figure 15 As shown, the remaining three rows of guide holes 4 on the positioning mother board 1 and the four rows of magnetic steel spaced between the two adjacent positioning mother boards 1 described in step c are connected to the threaded holes 2c, close to the positioning mother board The three rows of magnets on plate 1 align the threaded holes 2c.

[0122] Use the above method to install another positioning motherboard 1, such as Figure 16 As shown, move ...

Abstract

The invention discloses a method for processing threaded holes in a combination way. The method comprises the following step of step a, processing a locating mother board (1) and a locating guide board (8) by a CNC (Computer Numerical Control) planer type milling machine, wherein the locating mother board (1) and the locating guide board (8) are both arc-shaped boards, the curvatures of the outer arc-shaped surfaces of the locating mother board (1) and the locating guide board (8) are both equal to the curvature of the inner arc-shaped surface of a permanent magnet generator outer rotor (2), and the top part of the locating mother board (1) is provided with a seam allowance (3) which is bulged along the outer arc-shaped surface of the locating mother board (1). After the method disclosed by the invention is adopted, hole drilling and thread tapping can be guided through a plurality of guide holes in the locating mother board, the processing accuracy is high, the operation is easy, and the processing speed is fast.

Description

technical field [0001] The invention relates to a combined method and device for processing threaded holes in wind power generators, in particular to a method and device for processing magnetic steel joint threaded holes in the outer rotor of a large-scale direct-drive wind power permanent magnet generator. Background technique [0002] In the outer rotor type direct drive wind power permanent magnet generator, there are usually several magnets in the array of the inner arc surface of the outer rotor. Column distribution. [0003] Usually, the magnetic steel is bonded to the inner circumferential surface of the outer rotor, but in this way, due to the poor service life and reliability of the glue, it is difficult to guarantee the service life and reliability of the device as a whole. In order to improve the reliability of the connection, the outer rotor and the magnetic steel are usually fastened through threaded connection. Specifically, it is first necessary to set sever...
