[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-4 As shown, a generator assembly fixture includes a base 11; a lower positioning seat 12 is fixedly connected to the top of the base 11, a plurality of uprights 14 are fixedly connected to the top of the lower positioning seat 12, a sliding seat 15 is slidably connected to the uprights 14, a frame 16 is fixedly connected to the sliding seat 15, an upper positioning seat 17 is installed in the middle of the frame 16, a lower positioning pin 13 is fixedly connected to the top of the lower positioning seat 12, an upper positioning pin 18 is installed on the top of the upper positioning seat 17, and a lifting assembly is provided on the base 11; the lifting assembly includes a drive motor 22 and a lead screw 21, the lead screw 21 is rotatably connected to the base 11, the drive motor 22 is fixedly connected to the bottom of the base 11, the output end of the drive motor 22 is fixedly connected to the lead screw 21, and the lead screw 21 and the frame 16 are connected by a lead screw and nut pair;

[0024] In use, the front cover of the generator is installed in the upper positioning seat 17, and its upper positioning pin 18 passes through its lug hole. The lower positioning seat 12 is aligned with the rear cover, and then the lower positioning pin 13 passes through the lug hole of the rear cover for alignment and positioning. Then, the upper positioning seat 17 is moved down by the motor-driven lead screw 21 to complete the pressing and positioning of the front and rear covers of the generator. This reduces the manual insertion of positioning rods, making it convenient for workers to use and saving time and effort. The upright 14 and the sliding seat 15 that slides on the upright 14 can guide the frame 16 and the upper positioning seat 17, improving their stability.

[0025] Furthermore, such as Figure 1-5As shown, rotating shafts 42 are fixedly connected to both sides of the upper positioning seat 17. The rotating shafts 42 are rotatably connected to the frame 16. A tilting motor 41 is fixedly connected to the frame 16. A synchronous belt is installed between the output end of the tilting motor 41 and the rotating shafts 42. Sliding grooves are provided on both sides of the upper positioning seat 17. A fixing clamp 32 is slidably connected inside the sliding groove. A slider 34 is slidably connected to the bottom side of the upper positioning seat 17 via a sliding rail. A connecting rod is hinged between the slider 34 and the fixing clamp 32. 33. Grooves 35 are provided on both sides of the upper positioning seat 17. A push rod 36 is fixedly connected to the slider 34. The push rod 36 is inserted into the groove 35 and slidably connected to it. The push rod 36 passes through the rotating shaft 42 and is slidably connected to it. Guide plates 31 are fixedly connected to both sides of the base 11 and at the corresponding positions of the push rod 36. A first spring 52 is fixedly connected to the side wall of the slide groove. The end of the first spring 52 is fixedly connected to the fixing clip 32. A protrusion 51 is provided on the side of the guide plate 31.

[0026] During use, the end of the push rod 36 slides on the guide plate 31. During the up and down movement of the frame 16, the push rod 36 slides on the protrusion 51 on the side of the guide plate 31. The protrusion 51 of the guide plate 31 pushes the push rod 36 and the slider 34 to move. The slider 34 will drive the two fixing clamps 32 to move closer to each other through the connecting rod 33. When the two fixing clamps 32 close, they clamp to fix the front cover, so as to facilitate stable clamping. After the front and rear end covers are aligned, the upper positioning seat 17 drives the front cover to move down and presses the front cover and the rotor component down, pressing the bearing at the lower end of the rotor component into the bearing chamber of the rear end cover, completing the pressing of the front cover. After pressing a certain distance, the end of the push rod 36 leaves the protrusion 51 and releases the fixation. The spring is used to push the fixing clamps 32 to open.

[0027] During use, the upper positioning seat 17 is rotatably connected to the frame 16 via the rotating shaft 42. The rotating shaft 42 and the flipping motor 41 rotate via a synchronous belt. The flipping motor 41 is a servo motor, which controls the front cover to flip over, thus facilitating installation by the staff.

[0028] Furthermore, such as Figure 5 As shown, the upper positioning seat 17 and the upper positioning pin 18 are provided with sliding holes 61 at corresponding positions. The upper positioning pin 18 is inserted into the sliding hole 61 and slidably connected thereto. A second spring 62 is fixed between the bottom of the sliding hole 61 and the upper positioning pin 18.

[0029] In use, the upper positioning seat 17 has a sliding hole 61 for the upper positioning pin 18 to slide. After the upper positioning pin 18 and the lower positioning pin 13 are connected, they can slide into the sliding hole 61. Then, the lower positioning pin 13 is installed on both the front and rear end covers of the generator to keep the positioning of the front and rear end covers stable.

[0030] Furthermore, such as Figure 4 As shown, the end of the push rod 36 is connected to a ball bearing 7. In use, by relying on the ball bearing 7, the sliding friction between the end of the push rod 36 and the guide plate 31 can be reduced, making it easier to push the push rod 36 to move.

[0031] In operation, the generator's front end cover is installed inside the upper positioning seat 17, with its upper positioning pin 18 passing through its lug hole. The lower positioning seat 12 is aligned with the rear end cover, and then the lower positioning pin 13 passes through the lug hole of the rear end cover for positioning. The upper positioning seat 17 is then moved downwards by the motor-driven lead screw 21, thus completing the press-fitting and positioning of the generator's front and rear end covers. This reduces the need for manual insertion of positioning rods, making it more convenient and time-saving for operators. The upright 14 and the sliding seat 15 sliding on the upright 14 guide the frame 16 and the upper positioning seat 17, improving their stability.

[0032] During use, the end of the push rod 36 slides on the guide plate 31. During the up and down movement of the frame 16, the push rod 36 slides on the protrusion 51 on the side of the guide plate 31. The protrusion 51 of the guide plate 31 pushes the push rod 36 and the slider 34 to move. The slider 34 will drive the two fixing clamps 32 to move closer to each other through the connecting rod 33. When the two fixing clamps 32 close, they clamp to fix the front cover, so as to facilitate stable clamping. After the front and rear end covers are aligned, the upper positioning seat 17 drives the front cover to move down and presses the front cover and the rotor component down, pressing the bearing at the lower end of the rotor component into the bearing chamber of the rear end cover, completing the pressing of the front cover. After pressing a certain distance, the end of the push rod 36 leaves the protrusion 51 and releases the fixation. The spring is used to push the fixing clamps 32 to open.

[0033] During use, the upper positioning seat 17 is rotatably connected to the frame 16 via the rotating shaft 42. The rotating shaft 42 and the flipping motor 41 rotate via a synchronous belt. The flipping motor 41 is a servo motor, which controls the front cover to flip over, thus making it easier for staff to install.

[0034] In use, the upper positioning seat 17 has a sliding hole 61 for the upper positioning pin 18 to slide. After the upper positioning pin 18 and the lower positioning pin 13 are connected, they can slide into the sliding hole 61. Then, the lower positioning pin 13 is installed on both the front and rear end covers of the generator to keep the positioning of the front and rear end covers stable.
