[0006] Preferably, the feeding mechanism includes a mounting frame, a first motor, a roller, a conveyor belt and a support plate. The mounting frame is fixed on the workbench, and the first motor is installed on the mounting frame, and a roller is fixed to the output end of the first motor. At the same time, the roller bearing is connected to the mounting frame, and the roller is connected to the conveyor belt.

[0007] Preferably, a support plate is fixed symmetrically on the front and rear sides of the mounting frame, and the support plate contacts the lower end surface of the conveyor belt, and the width of the support plate is equal to the width of the conveyor belt. When the rotor is conveyed, the conveyor belt and the rotor can be lifted by the support plate, thereby avoiding deformation of the conveyor belt under the gravity of the rotor, thereby ensuring normal conveying and loading of the rotor.

[0008] Preferably, the moving mechanism includes a second motor, a threaded rod, a movable block, a cross bar and a limit block. The second motor is fixed on a fixed frame, and a threaded rod is fixed to the output end of the second motor, and the threaded rod bearing is connected to the fixed frame.

[0009] Preferably, the movable block and the cross bar are slidably connected, and the cross bar is fixed on the fixed frame. When the movable block moves, the sliding guide effect between the movable block and the cross bar can ensure the stability of the movable block's movement.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This generator rotor assembly equipment can clamp the rotor through the action of the cylinder and pneumatic clamping jaws. During the clamping process, the action of the push rod, the first spring and the limit ring can apply a certain pressure to the rotor to ensure that the rotor is in a horizontal state and prevent the rotor from tilting. When assembling the rotor, the cylinder and pneumatic clamping jaws can assemble the rotor and the generator housing on the limit mechanism. During the assembly process, the gear, the convex gear rod, the connecting rod and the vertical rod can drive the limit mechanism and the generator housing to rotate, ensuring that the installation position of the rotor and the generator housing is evenly stressed, thereby improving the assembly quality.

[0017] 2. When fixing the generator casing, the generator rotor assembly equipment places the generator casing on a circular plate. With the help of the generator casing's own gravity and the functions of the guide rod, slider and rotating rod, the position of the limit rod can be adjusted, thereby realizing the self-clamping effect of the generator casing. In the subsequent assembly process, the action of the cylinder and the rotor can apply force to the generator casing again, thereby realizing the secondary tightening of the generator casing and ensuring the stability of the generator casing fixation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The feeding mechanism 3 includes a mounting frame 301, a first motor 302, a roller 303, a conveyor belt 304 and a support plate 305. The mounting frame 301 is fixed to the workbench 1, and the first motor 302 is mounted on the mounting frame 301. The output end of the first motor 302 is fixed to the roller 303. At the same time, the roller 303 is connected to the mounting frame 301 by a bearing. The roller 303 is connected to the conveyor belt 304. The mounting frame 301 is also symmetrically fixed with a support plate 305 in front and back. The support plate 305 contacts the lower end surface of the conveyor belt 304, and the width of the support plate 305 is equal to the width of the conveyor belt 304.

[0029] When using the generator rotor assembly equipment, if Figure 1-Figure 7 As shown, the rotor to be assembled is placed on the conveyor belt 304. The first motor 302, the roller 303 and the conveyor belt 304 can realize automatic loading of the rotor. In addition, during the movement of the rotor, the support plate 305 can realize the lifting effect of the rotor and the conveyor belt 304, thereby preventing the conveyor belt 304 from being deformed under the gravity of the rotor. When the rotor moves to the bottom of the pneumatic clamp 504, the cylinder 501 is controlled to extend, thereby driving the fixed plate 502, the pneumatic clamp 504 and the ejector rod. 505 moves downward. Since the lower end surface of the push rod 505 is lower than the lower end surface of the upper jaw of the pneumatic clamp 504, the push rod 505 first contacts the rotating shaft on the rotor and applies force, thereby ensuring that the rotor is in a vertical state until the limit ring 507 contacts the pneumatic clamp 504 to achieve positioning. At this time, the upper jaw of the pneumatic clamp 504 is located outside the rotating shaft on the rotor. The pneumatic clamp 504 drives the jaw to move to achieve the rotor clamping effect.

The gear 602 and the convex gear rod 603 are meshed and connected. The convex gear rod 603 and the workbench 1 are slidably connected. One end of the connecting rod 604 is rotatably connected to the convex gear rod 603. The connecting rod 604 The other end is rotatably connected to the vertical rod 605. A second spring 606 is fixed between the vertical rod 605 and the connecting frame 607. The connecting frame 607 is fixed to the workbench 1. The cylinder 501 extends to drive the rotor clamped on the pneumatic clamp 504 for assembly, and cooperates with the pressure plate 503 to generate a force on the vertical rod 605. The transmission effect of the connecting rod 604 causes the convex gear rod 603 to move. The transmission effect between the convex gear rod 603 and the gear 602 causes the turntable 601 and the limit mechanism 7 to rotate.

[0031] The moving mechanism 4 includes a second motor 401, a threaded rod 402, a movable block 403, a cross bar 404 and a limit block 405. The second motor 401 is fixed to the fixed frame 2, and the output end of the second motor 401 is fixed with a threaded rod 402, and the threaded rod 402 is connected to the fixed frame 2 by a bearing. At the same time, the threaded rod 402 is connected to the movable block 403 through a thread, and the lower end surface of the movable block 403 is fixed with a cylinder 501; the movable block 403 and the cross bar 404 are in sliding connection, and the cross bar 404 is fixed to the fixed frame 2; the limit blocks 405 are fixed symmetrically on the left and right sides of the cross bar 404, and the limit blocks 405 contact with the movable block 403 to realize the limiting effect; the limiting mechanism 7 includes a circular plate 701, a guide rod 702, The slider 703, the limiting rod 704, the rotating rod 705, the sliding rod 706 and the third spring 707, the circular plate 701 is arranged just above the rotary disk 601, and the guide rod 702 is fixed at an equal angle on the circular plate 701, and the slider 703 is slidably connected to the guide rod 702, while the upper end surface of the slider 703 is fixed with the limiting rod 704; the lower end surface of the slider 703 is rotatably connected to one end of the rotating rod 705, and the other end of the rotating rod 705 is rotatably connected to the rotary disk 601; the lower end surface of the circular plate 701 is fixed with a sliding rod 706 at an equal angle, and the sliding rod 706 and the rotary disk 601 are slidably connected; one end of the third spring 707 is also fixed to the lower end surface of the circular plate 701, and the other end of the third spring 707 is fixed to the rotary disk 601;

[0032] When using the generator rotor assembly equipment, if Figure 1-Figure 7As shown, the generator housing with the stator installed is placed on the circular plate 701. The circular plate 701 is forced to move downward relative to the turntable 601 through the self-weight of the generator housing. With the transmission effect of the rotating rod 705, the slider 703 can slide on the guide rod 702, thereby adjusting the position of the limit rod 704 until the limit rod 704 contacts the generator housing to realize the limiting effect of the generator housing. After the generator housing is fixed, the movable block 403, the clamping mechanism 5 and the rotor can be moved to the right through the action of the second motor 401 and the threaded rod 402. With the sliding guide effect between the movable block 403 and the cross bar 404, the stability of the movable block 403 movement can be ensured until the movable block 403 contacts the right limit block 405 on the cross bar 404. At this time, the clamping mechanism 5 and the rotor are located just above the generator housing, and then the cylinder 501 is extended to drive, the fixed plate 502, the pressure plate 5 03 and the rotor move down for assembly. When the pressure plate 503 contacts the vertical rod 605, the vertical rod 605 is forced to move downward, and the transmission action of the connecting rod 604 causes the convex gear rod 603 to slide under force, and then the transmission action between the convex gear rod 603 and the gear 602 causes the turntable 601, the circular plate 701 and the generator casing to rotate. When the rotor and the generator casing are assembled, the cylinder 501 is extended to provide downward pressure on the rotor, and the rotation action of the generator casing can ensure that the installation position of the rotor and the generator casing is evenly stressed, thereby ensuring the assembly quality of the rotor and the generator casing. In the assembly process, the downward pressure generated by the rotor can provide a downward force on the generator casing and the circular plate 701. According to the above principle, the limit rod 704 can be further clamped on the generator casing, thereby ensuring the stability of the generator casing during assembly. This is the working principle of the generator rotor assembly equipment.
