Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a wind generator stator parallel link lead-out copper plate welding positioning tool, which can accurately position the relative position between the lead-out copper plate and the parallel link to ensure product welding quality. Background Art

[0002] The stator is an important part of the wind turbine. The size requirements of each component of the stator winding are relatively high to avoid interference between components during assembly, which makes assembly difficult. In the wind turbine, the stator parallel ring needs to be welded with a copper plate, which is connected to the junction box. The traditional copper plate is welded on the stator parallel ring and the distance is measured by a tape measure. This traditional measurement and positioning method will cause the following problems:

[0003] 1. The positioning is rough and the control of the offset angle is poor, which may cause difficulties in subsequent production and assembly, or even make assembly impossible;

[0004] 2. Each product includes multiple parallel links, and 1-2 lead copper plates need to be welded on each parallel link. Therefore, each product has a total of more than a dozen lead copper plates that need to be welded. The large number of lead copper plates can easily confuse the size and cause positioning errors;

[0005] 3. Every time a product is replaced, it is necessary to find its dedicated positioning tool, which hinders the improvement of production efficiency.

[0006] The size and position of each component of the stator product are unqualified, which seriously affects the normal production of the subsequent processes and makes the product prone to quality problems. Summary of the invention

[0007] The technical problem to be solved by the utility model is to provide a wind turbine stator and serial lead-out copper plate welding positioning tool in view of the deficiencies of the above-mentioned prior art. The wind turbine stator and serial lead-out copper plate welding positioning tool has accurate positioning and can ensure that the angle position of the lead-out copper plate is within the requirement; it has strong versatility and only needs to replace a small component, namely the positioning plate, to meet the positioning needs of various models.

[0008] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0012] The surface of the positioning plate is provided with a plurality of positioning rod connection holes, and one end of the positioning rod is detachably connected to the positioning rod connection hole on the positioning plate;

[0013] The flat plate is used for placing and linking, and the positioning rod is used for inserting into the through hole on the lead-out copper plate, thereby realizing the positioning of the lead-out copper plate on the flat plate.

[0014] As a further improved technical solution of the utility model, cross beams are fixedly connected between the two front vertical rods, between the two rear vertical rods, between one front vertical rod and the rear vertical rod, and between another front vertical rod and the rear vertical rod, and storage plates are fixedly connected between the four cross beams.

[0015] As a further improved technical solution of the utility model, the left mounting plate and the right mounting plate are both provided with strip-shaped mounting slots, the reserved mounting hole at the left end of the positioning plate is connected to the mounting slot on the left mounting plate by a bolt connection pair, and the reserved mounting hole at the right end of the positioning plate is connected to the mounting slot on the right mounting plate by a bolt connection pair.

The left mounting plate 32 is connected between a front vertical rod 1 and a rear vertical rod 2 on the left side, the right mounting plate 31 is connected between another front vertical rod 1 and another rear vertical rod 2 on the right side, the tops of the two rear vertical rods 2 are connected to the flat plates 4, and the tops of the flat plates 4 are fixedly connected to the stoppers 5.

[0032] Both the left mounting plate 32 and the right mounting plate 31 are provided with mounting slots 9 (i.e. waist-shaped holes); the reserved mounting hole at the left end of the positioning plate 12 is detachably connected to the mounting slot 9 on the left mounting plate 32; and the reserved mounting hole at the right end of the positioning plate 12 is detachably connected to the mounting slot 9 on the right mounting plate 31.

[0033] like Figure 6 As shown, a plurality of positioning rod connecting holes 13 are formed on the surface of the positioning plate 12 , and one end of the positioning rod 10 is detachably connected to the positioning rod connecting hole 13 on the positioning plate 12 .

[0034] The flat plate 4 is used for placing and connecting the rings 15 , and the positioning rod 10 is used for inserting into the through hole on the lead-out copper plate 14 , thereby realizing the positioning of the lead-out copper plate 14 on the flat plate 4 .

[0035] In this embodiment, cross beams 6 are fixedly connected between two front vertical bars 1, between two rear vertical bars 2, between one front vertical bar 1 and rear vertical bar 2, and between another front vertical bar 1 and rear vertical bar 2, and storage boards 8 are fixedly connected between the four cross beams 6. There are multiple storage boards 8.

[0036] In this embodiment, both the left mounting plate 32 and the right mounting plate 31 are provided with strip-shaped mounting slots 9, the reserved mounting hole at the left end of the positioning plate 12 is connected to the mounting slot 9 on the left mounting plate 32 via a bolt connection pair, and the reserved mounting hole at the right end of the positioning plate 12 is connected to the mounting slot 9 on the right mounting plate 31 via a bolt connection pair.

[0037] In this embodiment, Figure 5 As shown, one end of the positioning rod 10 is a threaded end 11 , and the positioning rod connecting hole 13 on the positioning plate 12 is a threaded hole. The threaded end 11 is threadedly connected to the positioning rod connecting hole 13 on the positioning plate 12 .

[0038] In this embodiment, a shoulder 16 is provided on the top of the threaded end 11 of the positioning rod 10 , and the shoulder 16 is used to contact around the top of the positioning rod connecting hole 13 on the positioning plate 12 to achieve positioning connection.

[0039] In this embodiment, the base frame is a base frame trolley, that is, a plurality of rollers 7 are provided at the bottom of the base frame.

[0040] In this embodiment, the chassis trolley is used to carry the positioning rod 10 and the positioning plate 12. The positioning plate 12 is used to determine the position of the lead-out copper plate 14; the positioning rod 10 is used to directly contact and limit the lead-out copper plate 14 to ensure that the extension distance and deflection angle of the lead-out copper plate 14 meet the requirements.

[0041] The position of the positioning rod connection hole 13 on the positioning plate 12 of this embodiment is designed according to the relative position of the lead-out copper plate 14 and the parallel link 15 required in the design drawings of different types of wind turbines. Since the connection position of the lead-out copper plate 14 and the parallel link 15 is different in different types of wind turbines, the position of the positioning rod connection hole 13 on the positioning plate 12 corresponding to different types of wind turbines will be different. In the same wind turbine, since there are multiple parallel links, multiple positioning rod connection holes 13 can be opened on the same positioning plate 2, so that multiple positioning rod connection holes 13 are suitable for the installation of the lead-out copper plates on multiple parallel links in the same wind turbine. It is also possible to obtain the installation position of the positioning plate 2 on the strip installation notch 9 on the left mounting plate 32 and the strip installation notch 9 on the right mounting plate 31 in advance according to the relative position of the lead-out copper plate 14 and the parallel link 15 required in the design drawings of the wind turbine, and record the position to facilitate the positioning installation of the lead-out copper plate 14 on the same parallel link next time.

[0042] The working principle of the utility model is: when in use, move the positioning tool of this embodiment to the welding area, select the positioning plate 12 corresponding to the product (wind turbine) model, in this embodiment, two through holes are reserved on the lead-out copper plate 14, and two positioning rods 10 are required for positioning. First, connect the two ends of the positioning plate 12 to the strip mounting slot 9 on the left mounting plate 32 and the strip mounting slot 9 on the right mounting plate 31 through a bolt connection pair, respectively. Do not tighten the nuts in the bolt connection pair, so that the two ends of the positioning plate 12 can move in the strip mounting slot 9; thread the threaded ends 11 of the two positioning rods 10 to two paired positioning rod connection holes 13 in the positioning plate 12; as shown in FIG. Figure 7-8As shown, the parallel link 15 is lifted onto the two flat plates 4 on the chassis trolley and pressed against the two stoppers 5 on the chassis trolley, and the parallel link 15 and the flat plates 4 are clamped with pliers so that the parallel link 15 does not move; two positioning rods 10 are respectively inserted into the two through holes on the lead-out copper plate 14 or one positioning rod 10 is inserted into one through hole on the lead-out copper plate 14; the lead-out copper plate 14 is placed on the parallel link 15, and the position of the positioning plate 12 in the strip mounting slot 9 is adjusted (this position can also be obtained in advance through the positional relationship between the lead-out copper plate 14 and the parallel link 15 in the design drawing) so that one side of the lead-out copper plate 14 does not exceed the inner ring edge of the parallel link 15 (the specific position is adjusted according to the design drawing), and then, the nut in the locking bolt connection pair is tightened to fix the position of the positioning plate 12 on the strip mounting slot 9, and at the same time, the lead-out copper plate 14 and the parallel link 15 are clamped with pliers, and the lead-out copper plate 14 and the parallel link 15 are welded. Figure 7-Figure 8 The parallel ring 15 is in the form of a circular ring, and only a partial structure is shown in the figure.

[0043] If there is only one through hole on the lead-out copper plate 14, the angular position of the lead-out copper plate can be adjusted according to the lead-out copper plate 14 required in the design drawing and the installation angle in the corresponding link 15.

[0044] The tool for welding and positioning the stator and serial lead-out copper plates of the wind turbine of this embodiment has a low tooling manufacturing cost; accurate positioning, ensuring that the angle position of the lead-out copper plate 14 is within the requirement; strong versatility, only needing to replace a small component, namely the positioning plate 12, to meet the positioning needs of various models; avoiding the investment in measuring and positioning tools of various sizes, facilitating on-site tool management and use, improving production efficiency, and ensuring product quality; with built-in rollers 7 for easy movement; the chassis trolley has multiple storage layers 8 for convenient material placement.
