Description

Technical Field

[0001] The utility model relates to the technical field of generator rotor assembly, in particular to a generator rotor assembly high-efficiency positioning tool. Background Art

[0002] The generator rotor is an important component of the generator. Generally, the generator rotor is installed inside the generator casing and fixed by the generator base. Therefore, the installation of the generator rotor is an important part of completing the generator production.

[0003] However, traditional rotor assembly positioning tools need to be installed manually, which is inefficient. Some installations use a slide, which is then pulled out. However, the slide is likely to bring the rotor back synchronously when it is pulled out, affecting the installation. In addition, the size of the slide does not match the rotor, and there is no structure to make up for the distance difference, which limits the installation of the slide. In addition, the generator casing cannot be fixed during installation, affecting the stability of the installation. Utility Model Content

[0004] The main purpose of the utility model is to provide a generator rotor assembly efficient positioning tool, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] As a further solution of the utility model, two springs are respectively arranged between the rear parts of the two triangular blocks and the inner sides of the two ends of the hollow fixed plate, and the two springs are respectively adaptively matched with the positions of the two movable rods.

[0009] As a further solution of the utility model, one end of the two guide rods passes through the inner end of the arc-shaped slide plate, and the multi-section electric telescopic rod is arranged at one end of the base.

[0010] As a further solution of the utility model, the push plate and the arc-shaped slide plate are adaptively matched, and the arc-shaped slide plate is adaptively matched with the support platform 2 and the hollow fixed plate respectively.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a generator rotor assembly high-efficiency positioning tool comprises a base 1, a support platform 1 2 and a support platform 2 3 are respectively arranged on the top of the base 1, and an assembly structure 4 is arranged on the inner side of the support platform 2 3;

[0025] The assembly structure 4 includes an arc-shaped slide plate 5, which is slidably arranged on the inner side of the support platform 2 3. A push plate 6 is movably arranged on the inner side of the arc-shaped slide plate 5. The rear part of the push plate 6 is fixedly connected to one end of a multi-section electric telescopic rod 7. Two guide rods 8 are respectively arranged on both sides of the rear part of the push plate 6. A hollow fixed plate 9 is arranged near the middle of the top of the base 1. Movable rods 10 are movably arranged at both ends of the hollow fixed plate 9. One end of each of the two movable rods 10 is fixedly connected to a triangular block 11.

[0026] Place the generator casing on the top of the support platform 2, place the generator rotor on the inner side of the arc-shaped slide plate 5, start the multi-section electric telescopic rod 7, so that it acts on the push plate 6 to carry the guide rod 8 to slide on the inner side of the arc-shaped slide plate 5 toward the direction of the support platform 2. When the guide rod 8 reaches the maximum value, the multi-section electric telescopic rod 7 pushes the arc-shaped slide plate 5 on the inner side of the support platform 2 3 to slide in the direction of the support platform 2 through the push plate 6. When one end of the generator rotor is pressed against the two triangular blocks 11, the two triangular blocks 11 carry the two movable rods 10 to slide toward the two ends of the hollow fixed plate 9 respectively. When one end of the arc-shaped slide plate 5 is completely inserted into the interior of the generator casing and fits with the inner end of the generator casing, the generator rotor is completely inserted into the interior of the generator casing. At this time, since the generator rotor is completely inserted into the generator casing, the spring 12 carries the triangular block 11 and the movable rod 10 to rebound to the initial position. The triangular block 11 limits the other end of the generator rotor, and then the multi-section electric telescopic rod 7 is recovered until the arc-shaped slide plate 5 slides back to the initial position, and the installation of the generator rotor can be completed.

[0027] In this embodiment, two springs 12 are respectively arranged between the rear portions of the two triangular blocks 11 and the inner sides of both ends of the hollow fixing plate 9 , and the two springs 12 are respectively adaptively matched with the positions of the two movable rods 10 .

[0028] When the spring 12 loses the pressure, it can rebound to the initial position with the triangular block 11 and the movable rod 10 .

[0029] In this embodiment, one end of the two guide rods 8 passes through the inner end of the arc-shaped slide plate 5 , and the multi-section electric telescopic rod 7 is arranged at one end of the base 1 .

[0030] The guide rod 8 can make up the distance of the arc-shaped slide plate 5, so that the generator rotor can be better installed in the generator housing.

[0031] In this embodiment, the push plate 6 and the arc-shaped slide plate 5 are adaptively matched, and the arc-shaped slide plate 5 is adaptively matched with the support platform 2 3 and the hollow fixed plate 9 respectively.

[0032] The arc-shaped slide plate 5 supports the generator rotor.

[0033] In this embodiment, a positioning structure 13 is provided on the top of the base 1, and the positioning structure 13 includes two baffles 14, and the two baffles 14 are symmetrically arranged at the front and rear parts of the other end of the base 1. A bidirectional screw rod 15 is rotatably arranged between the two baffles 14, and two sliding rods 16 are respectively arranged between the two ends of the two baffles 14, and two positioning plates 17 are symmetrically slidably arranged outside the bidirectional screw rod 15.

[0034] When the generator housing is placed on the top of the support platform 2, the servo motor 18 is started to rotate the bidirectional screw 15, thereby causing the positioning plate 17 to slide outside the bidirectional screw 15 and the sliding rod 16. When the positioning plate 17 is close to the outside of the generator housing, the servo motor 18 is stopped, so that the positioning plate 17 can fix the generator housing.

[0035] In this embodiment, the bidirectional screw rod 15 and the two slide rods 16 all penetrate the bottom of the support platform 2 , and the two ends of the two positioning plates 17 are penetrated by the two slide rods 16 respectively.

[0036] The positioning plate 17 slides outside the bidirectional lead screw 15 and the slide rod 16 under the action of the servo motor 18 and the bidirectional lead screw 15 .

[0037] In this embodiment, one end of the bidirectional screw rod 15 passes through the baffle 14 located at the front of the base 1 and is fixedly connected to the output shaft of the servo motor 18. The servo motor 18 is arranged in front of the baffle 14, and the positioning plate 17 is adaptably matched with the bidirectional screw rod 15 and the sliding rod 16.

[0038] The slide bar 16 has a limiting effect on the positioning plate 17 .

[0039] It should be noted that the utility model is a generator rotor assembly high-efficiency positioning tool, which can be placed at a site where work is required to achieve working conditions when in use;

[0040] When the guide rod 8 reaches the maximum value, the multi-section electric telescopic rod 7 pushes the arc slide 5 on the inner side of the support platform 2 3 to slide in the direction of the support platform 2. When one end of the generator rotor is pressed against the two triangular blocks 11, the two triangular blocks 11 carry the two movable rods 10 to slide toward the two ends of the hollow fixed plate 9 respectively. When one end of the arc slide 5 is fully inserted into the interior of the generator housing and fits with the inner end of the generator housing, the generator rotor is fully inserted into the interior of the generator housing. At this time, since the generator rotor is fully inserted into the generator housing, the spring 12 brings the triangular block 11 and the movable rod 10 back to the initial position. The triangular block 11 limits the other end of the generator rotor, and then the multi-section electric telescopic rod 7 is recovered until the arc slide 5 slides back to the initial position, and the installation of the generator rotor can be completed.

[0041] During the process, when the generator housing is placed on the top of the support platform 2, the servo motor 18 is started to rotate the bidirectional screw rod 15, thereby causing the positioning plate 17 to slide outside the bidirectional screw rod 15 and the sliding rod 16. When the positioning plate 17 is close to the outside of the generator housing, the servo motor 18 is stopped, so that the positioning plate 17 can fix the generator housing.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
