Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pole key pulling tooling, in particular to a convenient magnetic pole key pulling tooling. Background Art

[0002] When the generator rotor poles are modified, the pole keys need to be driven in after the poles are mounted. In order to make it easier to pull out the poles later, the pole keys need to be ground before they are finally driven in so that the contact surface of the primary and secondary keys reaches more than 70%. Therefore, the pole keys need to be repeatedly driven in, pulled out, and ground until the contact surface meets the requirements. In order to meet the qualified requirements, a convenient pole key extraction tool is used to plug and unplug the equipment.

[0003] Prior art includes a utility model with a publication number of CN219960334U, which discloses a pole key extraction tool for the generator rotor pole key during the grinding and matching.

[0004] In daily work, when plugging and unplugging the internal rotor of the equipment's motor, there is a problem that when the equipment is plugging and unplugging the rotor inside the motor, the motor casing is easy to move with the rotor, resulting in the rotor being difficult to detach from the motor casing when the equipment is plugged and unplugged, making it difficult for the equipment to quickly pull the rotor out of the motor. Utility Model Content

[0007] Furthermore, a groove is provided at one end of the connecting arm, and a pull rod is slidably connected to the inner wall of the groove. By setting the connecting arm, the limiting ring can be moved in a limited position, thereby reducing the situation where the limiting ring is difficult to move when the device is in use.

[0008] Furthermore, one end of the pull rod is fixedly connected to a spring, the end of the spring away from the pull rod is fixedly connected to the inner wall of the pull groove, and the end of the pull rod away from the spring is fixedly connected to a connecting rod. The spring is provided to facilitate the application of a reset elastic force to the pull rod.

[0009] Furthermore, one end of the connecting rod is fixedly connected with an adjusting rod, and the adjusting rod is engaged with the inside of the adjusting slot. The adjusting rod is provided to facilitate limiting the connecting rod.

[0010] Furthermore, a clamping device is provided on the surface of the connecting column, and the clamping device includes a clamping top plate and a clamping block.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the device is in use, the user places the motor that needs to be plugged in and out on the surface of the placement plate and then starts the cylinder. The movement of the cylinder drives the connecting column to move, and the movement of the connecting column drives the clamping top plate to clamp the rotor. Then the cylinder moves to drive the rotor to be pulled out. When the device is in use, the user pulls the connecting rod, and then the connecting rod moves to drive the pull rod and the adjusting rod to move. When the pull rod moves, it drives the spring displacement deformation to generate elastic force, and then the adjusting rod moves out of the inside of the adjusting groove, and then the connecting arm loses its restraint, and the connecting arm is pulled to move on the surface of the sliding rod, and then the movement of the connecting arm drives the limiting ring to move and adjust. By setting the limiting device, the motor casing is effectively restricted, which plays a role in restricting the motor casing, reducing the use of the device. When the device is in use, when the device is plugging and unplugging the rotor inside the motor, the motor casing is easy to move with the rotor, causing the rotor to be difficult to detach from the inside of the motor casing when the device is plugged and unplugged, causing the device to be difficult to quickly pull the rotor out of the motor, thereby improving the practicability of the device.

[0015] 2. In the utility model, by setting a clamping device, when the equipment is in use, the user starts the servo motor, and then the servo motor rotates to drive the threaded rod to rotate, and the threaded rod rotates to drive the sliding arm to move. When the sliding arm moves, it drives the clamping block to move, and then the clamping block and the rotor are clamped, which plays a role in clamping the rotor. When the equipment is in use, the clamp in the equipment is difficult to firmly clamp rotors of different sizes, which makes it difficult for the equipment to firmly clamp different models, thereby improving the practicability of the equipment.

[0026] Specifically, a groove 66 is formed at one end of the connecting arm 63 , and a pull rod 67 is slidably connected to the inner wall of the groove 66 .

[0027] In this embodiment, the connection arm 63 is provided to limit the movement of the restriction ring 61, thereby reducing the possibility that the restriction ring 61 is difficult to move when the device is in use.

[0028] Specifically, one end of the pull rod 67 is fixedly connected to a spring 68, and the end of the spring 68 away from the pull rod 67 is fixedly connected to the inner wall of the pull groove 66, and the end of the pull rod 67 away from the spring 68 is fixedly connected to a connecting rod 69. The spring 68 is provided to facilitate the application of a reset elastic force to the pull rod 67.

[0029] Specifically, one end of the connecting rod 69 is fixedly connected to an adjusting rod 610 , and the adjusting rod 610 is engaged with the inside of the adjusting slot 65 . The adjusting rod 610 is provided to facilitate limiting the connecting rod 69 .

[0030] In this embodiment: a clamping device 7 is provided on the surface of the connecting column 5, and the clamping device 7 includes a clamping top plate 77 and a clamping block 71. The clamping top plate 77 is fixedly connected to one end of the connecting column 5, and the clamping block 71 is arranged on the lower surface of the clamping top plate 77. A sliding arm 72 is fixedly connected to the surface of the clamping block 71. The sliding arm 72 is slidingly connected to the inner wall of the clamping top plate 77. The inner wall of the sliding arm 72 is threadedly connected to a threaded rod 74, and the threaded rod 74 is rotatably connected to the inner wall of the clamping top plate 77.

[0031] In this embodiment, by providing the clamping block 71, the rotor can be clamped and restricted, thereby reducing the possibility that the rotor is difficult to restrict when the device is in use.

[0034] Working principle: When the device is in use, the user places the motor to be plugged in and out on the surface of the placement plate 2 and then starts the cylinder 4. The cylinder 4 moves to drive the connecting column 5 to move. The connecting column 5 moves to drive the clamping top plate 77 to clamp the rotor. Then the cylinder 4 moves to drive the rotor to be pulled out. When the device is in use, the user pulls the connecting rod 69, and then the connecting rod 69 moves to drive the pull rod 67 and the adjusting rod 610 to move. When the pull rod 67 moves, it drives the spring 68 to displace and deform to generate elastic force. Then the adjusting rod 610 moves out of the inside of the adjusting groove 65, and then the connecting arm 63 loses its restraint, and the connecting arm 63 is pulled to move on the surface of the sliding rod 64. Then the connecting arm 63 moves to drive the limiting ring 61 to move and adjust. By setting the limiting device 6, the motor housing is effectively restricted, which plays a role in restricting the motor housing, reducing the use of the device. When the device is plugging and unplugging the rotor inside the motor, the motor housing is more likely to move with the rotor, causing the rotor to be difficult to detach from the inside of the motor housing when the device is plugged and unplugged, causing the device to be difficult to quickly pull the rotor out of the motor, thereby improving the practicality of the device.

[0035] When the device is in use, the user starts the servo motor 75, and then the servo motor 75 rotates to drive the threaded rod 74 to rotate, and the threaded rod 74 rotates to drive the slide arm 72 to move. When the slide arm 72 moves, it drives the clamping block 71 to move, and then the clamping block 71 clamps the rotor, thereby clamping the rotor. This reduces the problem that when the device is in use, the clamp in the device is difficult to firmly clamp rotors of different sizes and models, making it difficult for the device to firmly clamp different models, thereby improving the practicability of the device.
