[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] According to an embodiment of the present invention, a flaw detection device for a generator is provided.
[0034] Example 1;
[0035] like Figure 1-5 As shown, the flaw detection device for a generator according to an embodiment of the present invention includes a base 1, a first motor 2, and a movable seat 6. The output shaft of the first motor 2 is fixedly connected to a first threaded rod 201 via a coupling. The movable seat 6 is threadedly engaged with the outer wall of the first threaded rod 201. A support frame 104 is fixedly connected to the front end of the upper end of the base 1. A rack 108 is fixedly connected to both sides of the inner wall of the support frame 104. A dual-axis motor 603 is fixedly connected to the center position inside the movable seat 6. The output shafts at both ends of the dual-axis motor 603 are fixedly connected to a third threaded rod 604 via a coupling. A connecting plate 606 is movably connected to both ends of the movable seat 6. The bottom of the connecting plate 606 is threadedly engaged with the outer wall of the third threaded rod 604. A connecting rod 608 is rotatably connected to the upper end of the connecting plate 606. A gear 6010 is fixedly connected to one end of the connecting rod 608. A fixing plate 609 is fixedly connected to the end of the connecting rod 608 away from the gear 6010. The gear 6010 and the rack 108 mesh with each other.
[0036] In this embodiment, the first motor 2 drives the first threaded rod 201 to rotate, which in turn drives the movable seat 6 to slide. This causes the gear 6010 to drive the fixed plate 609 to rotate under the action of the rack 108, thereby driving the fixed generator to be tested to rotate, thus ensuring a larger range of phosphor dispersal.
[0037] Example 2;
[0038] like Figure 1-5 As shown, in the flaw detection device for a generator according to an embodiment of the present invention, a support plate 101 is fixedly connected to the front and rear ends of the base 1. A first motor 2 is fixedly connected to one end of the support plate 101. A first threaded rod 201 is movably connected to the inside of the support plate 101 through a bearing. A threaded groove 601 is provided inside the movable seat 6. The threaded groove 601 and the first threaded rod 201 are engaged. The first threaded rod 201 is threadedly engaged inside the threaded groove 601. A limit rod 102 is fixedly connected between the support plates 101. A first limit groove 602 is provided at the bottom of the movable seat 6. The limit rod 102 is slidably connected inside the first limit groove 602. A second limit groove 605 is provided at both ends of the movable seat 6. Limit blocks 607 are fixedly connected to both sides of the bottom of the connecting plate 606. The limit blocks 607 and the second limit groove 605 are adapted to each other. The connecting plate 606 is slidably connected to both ends of the movable seat 6 through the limit blocks 607 and the second limit groove 605.
[0039] In this embodiment, when the first motor 2 drives the first threaded rod 201 to rotate, it can cause the movable seat 6 to slide under the action of the threaded groove 601. The limiting rod 102 and the first limiting groove 602 can limit the movable seat 6, so that the movable seat 6 will not be driven to rotate by the first threaded rod 201 and will rotate along with it. The limiting block 607 and the second limiting groove 605 can limit the connecting plate 606, so that the connecting plate 606 will not be driven to rotate by the third threaded rod 604 and will rotate along with it.
[0040] Example 3;
[0041] like Figure 1-5 As shown, in the flaw detection device for a generator according to an embodiment of the present invention, a storage box 3 is slidably connected to the upper end of a support frame 104. Discharge ports 301 are provided on both sides of the bottom of the storage box 3. A slot 105 is formed at the upper end of the support frame 104, and the discharge ports 301 are located inside the slot 105. A slider 302 is fixedly connected to the bottom of the storage box 3. A limiting plate 106 is fixedly connected to the middle position of the upper end of the support frame 104. A sliding groove 107 is formed inside the limiting plate 106, and the slider 302 is slidably connected inside the sliding groove 107. One end of the 4 is fixedly connected to a second motor 4. The output shaft of the second motor 4 is fixedly connected to a second threaded rod 401 through a coupling. The second threaded rod 401 is threadedly engaged inside the slider 302. A connecting block 303 is fixedly connected to the bottom of the slider 302. A sieve plate 304 is fixedly connected to the bottom of the connecting block 303. A detection module 103 is fixedly connected to the rear end of the upper end of the base 1. A magnetic induction module 5 is provided at the rear end of the bottom of the base 1. The magnetic induction module 5 includes a DC power supply 501. Electrode rods 502 are fixedly connected to both sides of the DC power supply 501.
[0042] In this embodiment, the second motor 4 can drive the second threaded rod 401 to rotate, so that the second threaded rod 401 drives the slider 302 to slide under the action of the thread meshing with the outer wall of the second threaded rod 401, thereby driving the storage box 3 to slide and spread fluorescent powder on the generator to be tested. The electrode rods 502 are set on both sides of the DC power supply 501. The generator that is delivered to the inside of the detection module 103 will be manually equipped with two electrode rods 502. The DC power supply 501 is used to make the generator carry a DC current that is not enough to damage the generator, so that it becomes magnetic.
[0043] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0044] In practical applications, the generator to be tested is first placed between two fixed plates 609. Then, the first motor 2 is started to drive the first threaded rod 201 to rotate, causing the movable seat 6 to slide. At this time, the gear 6010, under the action of the rack 108, drives the fixed plate 609 to rotate, thereby driving the fixed generator to be tested to rotate. Simultaneously, fluorescent powder with partial magnetic force is poured into the storage box 3. The fluorescent powder will fall onto the sieve plate 304 through the discharge port 301. At the same time, the second motor 4 can be started to drive the second threaded rod 401 to rotate, so that the second threaded rod 401 drives the slider 302 to slide under the action of the thread meshing with the outer wall of the second threaded rod 401. The movement causes the storage box 3 to slide and spread fluorescent powder onto the generator under test. At the same time, it causes the sieve plate 304 to slide, causing the fluorescent powder to fall continuously. Thus, the fluorescent rod covers the generator under test. Then, the first motor 2 drives the first threaded rod 201 to rotate, causing the movable seat 6 to slide and move the generator under test to the position of the detection module 103. After the magnetic induction module 5 processes the generator, the detection module 103 can see the fluorescent powder accumulation at the cracked parts on the surface of the device. Thus, this non-destructive method can be used to perform flaw detection on the generator. This design uses magnetic particle flaw detection, which uses magnetic field and magnetic powder particles to detect cracks and defects in the generator core or axial direction.
[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
