Description

Technical Field

[0001] This utility model belongs to the field of generator processing technology, specifically a rotor device tooling for power generation. Background Technology

[0002] With the rapid development of new energy power generation, smart grids, and industrial automation technologies, generators, as core equipment for energy conversion, directly impact the stability and reliability of power generation systems through the assembly precision and production efficiency of their rotor shafts. In recent years, the global demand for high-efficiency generators in new energy sectors such as wind power and photovoltaic energy storage has grown by over 20% annually, with high-precision press-fitting processes becoming a key factor restricting capacity upgrades. Against this backdrop, automated press-fitting equipment is gradually replacing traditional manual operations, improving assembly efficiency through the integration of pneumatic drives, intelligent positioning, and other technologies.

[0003] Current generator rotor shaft press-fitting equipment mostly adopts a single fixed positioning structure. During the press-fitting process, the rotor shaft is prone to axial displacement or radial misalignment due to uneven support or force deviation, resulting in misalignment between the bearing and the shaft, which directly affects the service life of the generator. For example, some equipment uses a single-sided screw to fix the rotor shaft, and the lateral force cannot be balanced during press-fitting, often resulting in shaft misalignment. At the same time, the positioning parts and clamping structures of existing tooling are mostly fixed designs. When dealing with rotor shafts of generators of different lengths or diameters, the entire set of fixtures must be manually replaced, with a single adjustment taking more than 20 minutes, and it is difficult to guarantee repeatability and positioning accuracy.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of the present utility model.

[0025] Example:

[0026] A tooling for a generator rotor device, such as Figure 1 As shown, it includes a base plate 1, a push cylinder 4, a movable seat 2, a placement seat 10, and a fixed seat 8; the push cylinder 4 is connected to the base plate 1, the movable seat 2 is movably connected to the base plate 1, the piston rod of the push cylinder 4 is connected to the movable seat 2, the fixed seat 8 is fixedly connected to the base plate 1, and the placement seat 10 is disposed between the movable seat 2 and the fixed seat 8, and the placement seat 10 is used to support the rotor shaft 14 of the generator; the movable seat 2 is provided with a mounting head 5, and the fixed seat 8 is provided with a fixing head 7; wherein, as... Figure 2 As shown, the mounting head 5 is fixedly connected to the movable base 2. The top of the fixed head 7 has a placement groove 11 on one side near the fixed base 8, and a movable groove 12 on the other side; as shown... Figure 3 As shown, the top of the fixing head 7 is provided with a positioning groove 18, and the top of the fixing head 7 is also connected with a positioning component 16. The positioning component 16 is detachably and fixedly connected to the fixing head 7. A clamping screw 17 is threadedly connected to the positioning component 16, and the bottom of the clamping screw 17 extends into the positioning groove 18.

[0027] Specifically, in use, the generator rotor shaft 14 is placed on the mounting base 10. By moving the rotor shaft 14 or the mounting base 10, one end of the rotor shaft 14 is inserted into the positioning groove 18 on the top of the fixed head 7, while the end of the rotor shaft 14 abuts against the fixed head 7, achieving initial positioning. The radial movement of the rotor shaft 14 is restricted by the matching of the groove shape with the end of the rotor shaft 14. Using the positioning member 16 detachably connected to the fixed head 7, the clamping screw 17 is threaded onto the positioning member 16, and the screw is tightened so that its bottom extends into the positioning groove 18, pressing one end of the rotor shaft 14 against the fixed head 7. The bearing 13 is placed in the mounting groove 11 on the top of the mounting head 5 of the movable seat 2. The inner ring of the bearing 13 matches the shape of the mounting groove 11, ensuring that the bearing 13 is placed stably. The push cylinder 4 is activated, and the piston rod of the cylinder drives the movable seat 2 to slide along the base plate 1. The movable seat 2 drives the mounting head 5 to move towards the fixed seat 8. The mounting head 5 pushes the bearing 13 toward the rotor shaft 14, and the inner ring of the bearing 13 gradually fits into the rotor shaft 14. Simultaneously, the movable groove 12 on the mounting head 5 provides space for the rotor shaft 14 to pass through, preventing interference between the mounting head 5 and the rotor shaft 14 during movement, ensuring that the bearing 13 is smoothly pressed into the designated position on the rotor shaft 14. The cooperation of the positioning groove 18, the clamping screw 17, and the placement seat 10 ensures that the rotor shaft 14 remains stable during the pressing of the bearing 13, preventing displacement or misalignment and guaranteeing assembly accuracy. The detachable positioning element 16 and the threaded clamping screw 17 facilitate the installation and removal of the rotor shaft 14, improving operational convenience.

[0028] In a preferred embodiment, such as Figure 1 As shown, a slide rail 9 is provided on the base plate 1, and the bottom of the movable seat 2 slides in engagement with the slide rail 9. The slide rail 9 on the base plate 1 and the sliding engagement with the bottom of the movable seat 2 guide the movable seat 2 to move smoothly along the slide rail 9, ensuring the motion accuracy of the movable seat 2 when driving the mounting head 5 to press the bearing 13, and avoiding deviation; at the same time, it reduces the moving resistance of the movable seat 2, making the cylinder push smoother, and can also limit the moving direction of the movable seat 2 by the slide rail 9, ensuring the coaxiality of the bearing 13 and the rotor shaft 14 during the pressing process, improving assembly stability and device reliability.

[0029] In a preferred embodiment, both the movable seat 2 and the placement seat 10 are slidably engaged with the slide rail 9. The placement seat 10, being slidably engaged with the slide rail 9, can be adjusted along the slide rail 9 to accommodate rotor shafts 14 of different lengths. This ensures that the rotor shaft 14 accurately aligns with the positioning groove 18 of the fixed head 7, while also ensuring the stability of the rotor shaft 14 during movement. This prevents positional deviations from affecting the pressing accuracy of the bearing 13, thereby improving the adaptability and assembly stability of the device for rotors of different specifications.

[0030] In a preferred embodiment, the slide rail 9 has an I-shaped cross-section. Its upper and lower flanges can limit the lateral displacement of the movable seat 2 or the placement seat 10 during sliding, enhance guiding stability, and prevent the parts from falling out. The middle web reduces the amount of material used while ensuring structural strength, so that the slide rail 9 can withstand the load when the movable seat 2 moves. The groove design of the I-shaped cross-section can accommodate grease, reduce friction, improve sliding smoothness, and ensure stable operation of the device.

[0031] In a preferred embodiment, such as Figure 1 As shown, a mounting base 3 is fixedly connected to the base plate 1, and the push cylinder 4 is detachably connected to the mounting base 3. The mounting base 3 is fixedly connected to the base plate 1, and the push cylinder 4 is detachably connected to it, which facilitates the installation and removal of the cylinder, and makes it convenient for maintenance, repair, or replacement of cylinders of different specifications. The mounting base 3 provides a stable support for the cylinder, ensuring that the thrust direction of the cylinder piston rod is accurate and avoiding deviation of the movable seat 2 due to loose installation. At the same time, the detachable design enhances the flexibility of the device, adapts to different thrust requirements, and ensures stable and reliable power transmission when pressing the bearing 13.

[0032] In a preferred embodiment, such as Figure 1 As shown, a support frame 6 is fixedly connected to the placement seat 10, and the support frame 6 is used to place the rotor shaft 14. The support frame 6 fixedly connected to the placement seat 10 is used to place the rotor shaft 14. The structural design of the support frame 6 can be adapted to the shape of the rotor shaft 14, which facilitates the loading and unloading of the rotor shaft 14 and improves assembly efficiency and rotor support stability.

[0033] In a preferred embodiment, such as Figure 2 as well as Figure 4 As shown, an auxiliary positioning component 15 is detachably connected to the mounting head 5 near the fixed base 8. The auxiliary positioning component 15 includes a connecting lug 19 and an auxiliary alignment cylinder 20. The connecting lug 19 is symmetrically arranged on both sides of the auxiliary alignment cylinder 20. The inner hole of the auxiliary alignment cylinder 20 has a structure where one side has a larger opening and the other side has a smaller opening. The detachably connected auxiliary positioning component 15 on the mounting head 5 is fixed by the symmetrical connecting lug 19. The structure of the inner hole of the auxiliary alignment cylinder 20, which is larger at one end and smaller at the other, can utilize the guiding effect of the tapered hole when pressing the bearing 13. This allows the bearing 13 to be inserted from the side with the larger opening and gradually aligned with the rotor shaft 14 along the inner hole, ensuring the coaxiality of the bearing 13 and the rotor shaft 14 and reducing pressing deviation. The detachable design facilitates the replacement of auxiliary alignment cylinders 20 of different specifications to adapt to bearings 13 or rotor shafts 14 of different sizes, enhancing the versatility of the device. At the same time, the symmetrical connecting lug 19 ensures installation stability and improves the accuracy and efficiency of pressing the bearing 13.

[0034] In a preferred embodiment, a plug rod is fixedly connected to the mounting head 5, and a socket is provided on the connecting ear 19, with the plug rod engaging with the socket. The plug rod fixedly connected to the mounting head engages with the socket on the connecting ear 19, allowing for quick assembly of the auxiliary positioning component 15 and the mounting head 5 by inserting the plug rod into the socket. Installation and disassembly can be completed without additional tools, improving operational convenience.

[0035] In a preferred embodiment, the positioning element 16 is connected to the fixing head 7 by screws. The screw connection allows the positioning element 16 to be fixed to the fixing head by tightening the screws, ensuring that the clamping screw 17 can stably clamp the rotor shaft 14. The screw connection also facilitates the disassembly of the positioning element 16, making it convenient for the installation, removal, and maintenance of the rotor shaft 14. Furthermore, the installation position of the positioning element 16 can be adjusted according to the specifications of the rotor shaft 14, ensuring that the clamping screw 17 accurately acts on the rotor shaft 14.

[0036] In a preferred embodiment, two clamping screws 17 are symmetrically arranged on the positioning member 16. The two clamping screws 17 symmetrically arranged on the positioning member 16 can uniformly press the rotor shaft 14 into the positioning groove 18 by applying force symmetrically in both directions, avoiding the rotor shaft 14 from tilting due to unilateral force and ensuring coaxiality during fixation; the symmetrical structure makes the clamping force evenly distributed, enhances the fixation stability, prevents the rotor shaft 14 from shifting when pressing the bearing 13, and at the same time, the dual screw design can adjust the clamping force according to the diameter of the rotor shaft 14, adapting to different specifications of rotor shaft 14, improving the reliability and applicability of the fixing device.
