Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a generator rotor thickness measuring device. Background Art

[0002] The generator rotor is the rotating part of the generator, which includes the rotor shaft, iron core, magnetic poles and other components. The iron core of the rotor is generally composed of overlapping high-magnetic permeability material punchings. The structure of the punchings directly affects the efficiency, life, performance of the generator and the assembly production efficiency of the motor.

[0003] In the prior art, since the rotor thickness is the only criterion for measuring whether a generator is qualified, it is usually necessary to measure the required rotor thickness of the generator before assembling the generator. At present, the thickness of the rotor is generally measured using a corresponding sensor. However, when measuring the thickness of the generator rotor, the lack of a limit device will cause the generator rotor to tilt, which in turn affects the thickness measurement result of the generator rotor, resulting in a large error in the measurement result.

DETAILED DESCRIPTION

[0023] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5The utility model provides a technical solution: a generator rotor thickness measuring device, comprising: a workbench 1, a plurality of evenly distributed brackets 4 are fixedly installed on the top of the workbench 1, a housing 3 is fixedly installed on the top of the bracket 4, a plurality of evenly distributed thickness measuring sensors 6 are fixedly installed on the top of the housing 3, a limit assembly 2, the limit assembly 2 comprises a plurality of threaded seats 203, the threaded seats 203 are evenly distributed and fixedly installed on the middle of the outer periphery of the housing 3, the threaded seats 203 are all threadedly connected with threaded rods 202 and the threaded rods 202 all penetrate the housing 3, and the threaded rods 20 2 are rotated and installed with a limit plate 205 on one side close to each other, and the limit plate 205 is arc-shaped, and the generator rotor is placed on the notch 706 inside the placement seat 704. By rotating the auxiliary handle 201 on the threaded rod 202 and cooperating with the threaded seat 203, the limit plates 205 at the ends of the threaded rod 202 are brought close to each other until the generator rotor is limited and fixed, which can ensure that the generator rotor remains in a vertical state during the measurement process, avoiding measurement errors during the measurement process. Then, the controller can control the thickness measurement sensor 6 to measure the generator rotor. The thickness of the sub-assembly is measured and the measurement result is fed back to the controller. Here, the thickness measurement sensor 6 can be a PUSDT01 ultrasonic distance measuring thickness sensor, etc. The threaded rod 202 is fixedly installed with an auxiliary handle 201 at one end away from the placement seat 704, and the outer periphery of the auxiliary handle 201 is provided with an anti-slip groove, and the limiting plates 205 are fixedly installed with a flexible pad 204 on one side close to each other, and the limiting plates 205 are symmetrically fixedly installed with a telescopic rod 206 on one side away from the flexible pad 204, and the ends of the telescopic rods 206 away from the limiting plates 205 are fixedly installed on the same side. In the middle of the inner wall of the casing 3, since the limit plate 205 is arc-shaped, it can be well adapted to the outer periphery of the generator rotor. At the same time, the flexible protective pad 204 installed on the surface of the limit plate 205 can prevent the limit plate 205 from causing damage to the generator rotor when it contacts the generator rotor, thereby affecting the normal use of the generator rotor. At the same time, a telescopic rod 206 is installed on the surface of the limit plate 205, which can limit the limit plate 205 and prevent the limit plate 205 from rotating synchronously with the threaded rod 202, causing the limit plate 205 to tilt and affecting the limiting of the generator rotor.

[0025] The dust removal component 5 is arranged on the upper part of the casing 3. The dust removal component 5 includes a plurality of limit frames 505, each of which is fixedly installed in the middle of the top of the casing 3. Two connecting pipes 502 are fixedly installed in the middle of the limit frame 505 and are symmetrically distributed. A plurality of evenly distributed nozzles 501 are fixedly installed on the upper part of the outer periphery of each connecting pipe 502. A mounting frame 504 is symmetrically fixedly installed in the middle of the outer periphery of the casing 3. An air pump 503 is fixedly installed on the side of the mounting frame 504 away from the casing 3. The output end of the air pump 503 is connected to the connecting pipe 504. 02 is connected, and by controlling the air pump 503, the airflow can be transmitted to the nozzle 501 through the connecting pipe 502. At this time, the nozzle 501 will blow the airflow to the outer periphery of the generator rotor, which can clean the dust and impurities adhering to the outer periphery of the generator rotor to avoid errors in the measurement process. The rotating component 7 includes a placement seat 704, which is rotatably installed in the middle of the workbench 1. A notch 706 is opened in the middle of the top of the placement seat 704, and a plurality of evenly distributed card plates 70 are fixedly installed on the top of the placement seat 704. 5. A driving mechanism is provided at the lower part of the workbench 1, and the driving mechanism is used to rotate the placement seat 704. The driving mechanism includes a fixed frame 703, and the fixed frame 703 is fixedly installed at the bottom end of the workbench 1. A stepper motor 701 is fixedly installed in the middle of the fixed frame 703. A driving gear 702 is fixedly installed at the driving end of the stepper motor 701. The outer periphery of the driving gear 702 is meshed and connected with a driven gear 707. The driven gear 707 is fixedly installed at the bottom end of the placement seat 704. By controlling the stepper motor 701, the driving gear 702 can be driven to rotate. Since the driving gear 702 and the driven gear 707 are meshed with each other, the placement seat 704 will rotate synchronously at this time, and then the generator rotor on the placement seat 704 can be rotated at a uniform speed. Since a clamping plate 705 is provided on the surface of the placement seat 704, the clamping plate 705 will be inserted into the gap between the magnetic rings of the generator rotor to prevent the generator rotor and the placement seat 704 from rotating. In conjunction with the dust removal component 5, the outer periphery of the generator rotor can be fully dusted. The number of clamping plates 705 here can be set according to the number of gaps between the magnetic rings of the generator rotor.

[0026] During actual use, the staff places the generator rotor in the slot 706 on the placement seat 704, at which time the clamping plate 705 will be stuck in the gap between the rotor magnetic rings, and then the stepper motor 701 in the driving mechanism is controlled. The stepper motor 701 cooperates with the driving gear 702 and the driven gear 707 to drive the placement seat 704 to rotate slowly and evenly. At the same time, the air pump 503 in the dust removal component 5 cooperates with the connecting pipe 502 and the nozzle 501 to blow the airflow to the outer periphery of the generator rotor, so that the dust and impurities on the outer periphery of the generator rotor can be cleaned before detection. After cleaning, the staff rotates the auxiliary handle 201, and the auxiliary handle 201 can drive the threaded rod 202 to rotate, so that the limit plate 205 can move toward the surface of the generator rotor until the limit plate 205 is completely in contact with the outer periphery of the generator rotor. At this time, the generator rotor is in a vertical state, which can avoid the generator rotor from tilting during the measurement process, resulting in the measurement result being affected. Then, the thickness of the generator rotor can be measured by controlling the thickness measurement sensor 6 on the casing 3, and the measurement result can be fed back to the controller.
