[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 at the output end of the first motor.

[0009] Preferably, the movable block is slidably connected to the cross bar, and the cross bar is fixed on the fixed frame. When the movable block moves, the stability of the movement of the movable block can be ensured by the sliding guiding effect between the movable block and the cross bar.

[0016] 1. The generator rotor assembly equipment can clamp the rotor through the action of the cylinder and the pneumatic clamp, and in the clamping process, a certain pressure can be applied to the rotor through the action of the push rod, the first spring and the limit ring to ensure that the rotor is in a horizontal state and avoid the rotor from tilting. When assembling the rotor, the rotor and the generator housing on the limit mechanism can be assembled through the cylinder and the pneumatic clamp, and in the assembly process, the limit mechanism and the generator housing can be driven to rotate in coordination with the action of the gear, the convex gear rod, the connecting rod and the vertical rod, so as to ensure that the rotor and the generator housing are evenly stressed at the installation position, thereby improving the assembly quality;

[0017] 2. The generator rotor assembly equipment places the generator casing on a circular plate when fixing the generator casing. The position of the limit rod can be adjusted by the gravity of the generator casing itself and the action of the guide rod, slider and rotating rod, thereby realizing the self-clamping effect of the generator casing. In the subsequent assembly process, the force can be applied to the generator casing again through the action of the cylinder and the rotor, thereby realizing the secondary tightening effect of the generator casing and ensuring the stability of the generator casing fixation.

[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 on the workbench 1, and the first motor 302 is installed on the mounting frame 301, and the roller 303 is fixed to the output end of the first motor 302, and the roller 303 is connected to the mounting frame 301 with a bearing, and the roller 303 is connected to the conveyor belt 304; the support plate 305 is also fixed to the mounting frame 301 symmetrically, and 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 the process of the rotor moving, the support plate 305 can realize the lifting effect of the rotor and the conveyor belt 304, so as to prevent the conveyor belt 304 from being deformed under the gravity of the rotor.

The gear 602 and the convex gear rod 603 are meshedly 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, and a second spring 606 is fixed between the vertical rod 605 and the connecting frame 607.

The cylinder 501 is extended to drive the rotor clamped on the pneumatic clamp 504 to be assembled, and the pressure plate 503 is used to generate a force on the vertical rod 605, and the transmission effect of the connecting rod 604 is used to move the convex tooth rod 603. The transmission effect between the convex tooth 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 on 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, and the threaded rod 402 is connected to the movable block 403 by 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 slidably connected, and the cross bar 404 is fixed on 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 are in contact with the movable block 403 to realize the limiting effect; the limiting mechanism 7 includes a circular plate 701, a guide rod 702, Slider 703, limit rod 704, rotating rod 705, slide bar 706 and third spring 707, circular plate 701 is arranged directly above the rotating disk 601, and guide rod 702 is fixed at an equal angle on the circular plate 701, and slider 703 is slidably connected to the guide rod 702, and the upper end surface of the slider 703 is fixed with the limit 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 rotating disk 601; the lower end surface of the circular plate 701 is fixed with a slide bar 706 at an equal angle, and the slide bar 706 and the rotating 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 rotating 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.

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 movement of the movable block 403 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 directly 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 makes the convex tooth rod 603 slide under force, and then the transmission action between the convex tooth rod 603 and the gear 602 makes the turntable 601, the circular plate 701 and the generator casing rotate. When the rotor and the generator casing are assembled, the cylinder 501 is extended to provide downward pressure on the rotor. With the rotation of the generator casing, it can be ensured that the installation position of the rotor and the generator casing is uniformly stressed, thereby ensuring the assembly quality of the rotor and the generator casing, and during 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.
