Description

Technical Field

[0001] This utility model relates to the technical field of flywheel generator assembly equipment, specifically to a self-generating flywheel generator press-fitting machine. Background Technology

[0002] A self-generating flywheel generator is a system that combines flywheel energy storage technology with power generation. It stores and releases electrical energy through the high-speed rotation of the flywheel and possesses self-generating power capabilities. The core of the self-generating flywheel generator is utilizing the high-speed rotation of the flywheel to store and release energy. During energy storage, electrical energy is converted into mechanical energy (kinetic energy) and stored by a motor driven by a power converter, which in turn drives the flywheel to accelerate. When power generation is needed, the flywheel decelerates, and the motor operates as a generator, converting the mechanical energy back into electrical energy, outputting current and voltage to supply external loads. The flywheel generator mainly consists of a casing, central shaft, rotor, and bearings, and these components need to be assembled during production.

[0003] However, most current assembly equipment assembles each component of the flywheel unit separately. When assembling different components, the flywheel unit needs to be transported, which reduces assembly efficiency and makes it easy for bumps to occur during transportation, affecting assembly accuracy.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] refer to Figure 1-4The self-generating flywheel generator press-fitting machine of this embodiment includes a frame 1. A mounting frame 2 is fixedly connected to the bottom inner side of the frame 1. The mounting frame 2 has a U-shaped cross-section. A lifting mechanism 3 is vertically arranged on the inner wall of the mounting frame 2 to drive the flywheel generator housing to lift and lower. The lifting platform of the lifting mechanism 3 is equipped with a clamping mechanism 4 to fix the flywheel generator housing. A pressing mechanism 5 is arranged on the outer side of the mounting frame 2 to press and fix the various components during installation. The pressing mechanism 5 includes a movable frame 503. On the side of the mounting frame 2 away from the pressing mechanism 5, from bottom to top, there are a central shaft positioning cylinder 6, a central shaft mounting seat 8, a bearing mounting seat 9, and a pulley mounting seat 10. The central shaft positioning cylinder 6 is used to position the central shaft of the housing. On the side wall of the movable frame 503 facing the clamping mechanism 4, from bottom to top, there are a central shaft pressing head 11, a snap ring feeding mechanism 12, a bearing pressing head 13, and a... The clamping mechanism 4 includes a fixed plate 401 and a snap ring feeding mechanism 12 that automatically feeds snap rings during installation. A movable plate 402 is slidably connected to the top of the fixed plate 401. A pair of first limiting pins 403 are fixedly connected to the top of the fixed plate 401 facing the pressing mechanism 5. A pair of second limiting pins 406 are fixedly connected to the bottom of the movable plate 402 away from the pressing mechanism 5. A spring 407 connects adjacent first limiting pins 403 and second limiting pins 406. A pair of limiting blocks 404 are fixedly connected to the top of the movable plate 402. A pair of clamping cylinders 405 are fixedly connected to the outer side of the pair of limiting blocks 404. A limiting plate 408 is fixedly connected to the piston rod of each clamping cylinder 405. The sliding direction of the movable plate 402 and the extension and retraction direction of the clamping cylinders 405 are consistent with the pressing direction of the pressing mechanism 5. A contoured top rod 7 is fixedly connected to the piston rod of the central shaft positioning cylinder 6.During assembly, the components to be assembled are installed on the central shaft mounting base 8, bearing mounting base 9, and pulley mounting base 10, respectively. At this time, the initial position of the lifting platform of the lifting mechanism 3 is located at the bottom inner side of the frame 2. The flywheel unit housing, which is arranged in a ring, is placed between the limiting blocks 404, so that the axis of the housing is parallel to the extension and retraction direction of the central shaft positioning cylinder 6. Then, the clamping cylinder 405 drives the limiting plate 408 to move towards the housing, clamping and fixing the housing. Then, the lifting mechanism 3 drives the housing to move upward until it is coaxial with the piston rod of the central shaft positioning cylinder 6 and stops. At this time, the central shaft positioning cylinder 6 drives the contour push rod 7 to move towards the axis of the housing. The movement continues until it abuts against the side wall of the outer shell, then the limiting plate 408 is reset, the outer shell is released, and the position of the outer shell is adjusted according to the position of the contour push rod 7 until the contour push rod 7 can be inserted into the central shaft mounting hole in the middle of the outer shell. The outer shell is then fixed again, thereby positioning the assembly position of the outer shell. After positioning, the central shaft positioning cylinder 6 drives the contour push rod 7 to disengage from the outer shell, and the lifting mechanism 3 drives the outer shell to move upward until it is coaxial with the central shaft mounting seat 8 and stops. At this time, the central shaft is installed at the axis of the central shaft mounting seat 8. The pressing mechanism 5 drives the movable frame 503 and the central shaft pressure head 11 to move towards the outer shell. When the central shaft pressure head 11 contacts the outer shell... At this time, the housing and movable plate 402 move synchronously towards the central shaft mounting seat 8. The spring 407 is compressed, generating a spring force in the opposite direction on the movable plate 402 until the central shaft is inserted into and passes through the central shaft mounting hole at the center of the housing, thus achieving the press-fitting of the central shaft. At this time, the pressing mechanism 5 resets, and the movable plate 402 and housing automatically reset under the spring force, simultaneously causing the central shaft to disengage from the central shaft mounting seat. After the central shaft is installed, the lifting mechanism 3 moves the housing upwards to the snap ring feeding mechanism 12. At this time, the snap ring is manually installed on the end of the central shaft protruding from the housing and facing the movable frame 503. The snap ring feeding mechanism enables the installation of the central shaft. Automatic feeding of the snap ring; after installation, the lifting mechanism 3 drives the outer shell upward until it is coaxial with the bearing mounting seat 9 and stops. At this time, the flywheel module is installed at the end of the bearing pressure head 13, and the bearing is installed at the end of the bearing mounting seat 9. The flywheel module and the bearing are pressed onto both ends of the central shaft by the bearing pressure head 13, and the pressing process is the same as above. After pressing, the lifting mechanism 3 drives the outer shell upward until it is coaxial with the pulley mounting seat 10 and stops. At this time, the pulley is installed at the end of the pulley mounting seat, and the pulley is pressed onto the end of the central shaft by the pulley pressure head 14, and the pressing process is the same as above. This realizes the integrated assembly of the flywheel unit and effectively improves the assembly efficiency.

[0026] The pressing mechanism 5 includes a bidirectional motor 501, which is fixedly connected to the outer side wall of the mounting frame 2. A pair of drive bevel gears 504 are symmetrically fixedly connected to both ends of the rotating shaft of the bidirectional motor 501. A pair of lead screws 502 are horizontally rotatably connected between the top and bottom of the side wall of the mounting frame 2. The lead screws 502 are arranged perpendicularly to the rotating shaft of the bidirectional motor 501. A driven bevel gear 505 is fixedly connected to one end of the lead screw 502 facing the bidirectional motor 501. Adjacent driven bevel gears 505 are meshed with the drive bevel gears 504. A pair of guide rods 506 are arranged parallel to each other on both sides of the pair of lead screws 502. The movable frame 503 is slidably connected to the pair of guide rods 506 and threadedly connected to the lead screws 502. The extension and retraction direction of the central shaft positioning cylinder 6 is parallel to the guide rods 506. The central shaft mounting seat 8 and the central shaft pressure head 11 are coaxially arranged. When the pressing mechanism 5 is running, the bidirectional motor 501 drives the drive bevel gears 504 at both ends of its rotating shaft to start rotating. When the drive bevel gears 504 rotate, they drive the driven bevel gears 505 that mesh with them to start rotating, causing the lead screw 502 to start rotating. When the lead screw 502 rotates, it drives the movable frame 503 that is threadedly connected to it to start moving along the guide rod 506.

[0027] refer to Figure 5-6The snap ring feeding mechanism 12 includes a fixing block 1201, which is fixedly connected to the side wall of the movable frame 503 away from the bidirectional motor 501. A connecting plate 1202 is fixedly connected to the end of the fixing block 1201 away from the movable frame 503. The connecting plate 1202 is L-shaped. A lifting cylinder 1203 is vertically fixedly connected to the bottom of the connecting plate 1202. A top plate 1207 is fixedly connected to the piston rod of the lifting cylinder 1203. An mounting block 1204 is fixedly connected to the side wall of the connecting plate 1202 away from the fixing block 1201. A feeding plate 1209 is fixedly connected to the side wall of the mounting block 1204 away from the connecting plate 1202. The feeding plate 1209 faces the mounting block 1207. A feeding trough 1205 is provided in the middle of one side wall of 4. The top of the top plate 1207 extends into the interior of the feeding trough 1205 and is slidably connected to it. A picking trough 1208 is provided on the top of the feeding plate 1209. A pair of locking blocks are fixedly connected to both sides of the side wall of the picking trough 1208 facing the mounting block 1204. A feeding rack 1206 is fixedly connected in the middle of the side wall of the feeding plate 1209 facing the mounting block 1204. The feeding rack 1206 is inclined upward. The cross section of the feeding rack 1206 is arranged in a "+" shape. The feeding trough 1205 passes through both sides of the connection between the feeding rack 1206 and the feeding rack 1206. A lower slot is provided at the connection between the top plate 1207 and the feeding rack 1206. When the snap rings are being fed, several snap rings fitted on the outside of the feeding frame 1206 move towards the feeding plate 1209 under the action of gravity and fall into the inside of the feeding trough 1205. At this time, the lifting cylinder 1203 drives the top plate 1207 to move upward, lifting the snap rings inside the feeding trough 1205 until the snap rings move upward into the inside of the picking trough 1208. At this time, the snap rings can be taken out for easy installation.

[0028] refer to Figure 7 The bearing pressure head 13 is coaxially arranged with the bearing mounting base 9. A chuck 15 is fixedly connected to the end of the bearing pressure head 13 facing the bearing mounting base 9. The pulley mounting base 10 is coaxially arranged with the pulley pressure head 14. The flywheel module can be clamped and positioned by the chuck 15, which facilitates its installation.

[0029] Working principle: Before assembly, the components to be assembled are installed on the central shaft mounting seat 8, bearing mounting seat 9 and pulley mounting seat 10 respectively. At this time, the initial position of the lifting platform of the lifting mechanism 3 is located at the bottom of the inner side of the frame 2. The flywheel unit housing arranged in a ring is placed between the limit blocks 404, so that the axis of the housing is parallel to the extension and retraction direction of the central shaft positioning cylinder 6. Then, the clamping cylinder 405 drives the limit plate 408 to move towards the housing, clamping and fixing the housing.

[0030] During assembly, the lifting mechanism 3 moves the outer shell upward until it is coaxial with the piston rod of the central shaft positioning cylinder 6, at which point it stops. The central shaft positioning cylinder 6 then moves the contour push rod 7 towards the center of the outer shell until it abuts against the side wall of the outer shell, at which point it stops. Then, the limiting plate 408 resets, the outer shell is released, and the position of the outer shell is adjusted according to the position of the contour push rod 7 until it can be inserted into the central shaft mounting hole in the middle of the outer shell. The shell is then fixed again, thus positioning the assembly position of the shell. After positioning, the central shaft positioning cylinder 6 moves the contour push rod 7 away from the shell, and the lifting mechanism 3 moves the shell upward until it is coaxial with the central shaft mounting seat 8, at which point the central shaft is mounted at the center of the central shaft mounting seat 8. The pressing mechanism 5 then moves the movable frame 503 and the central shaft pressure head 11 towards the shell. When the pressing mechanism 5 is running, the bidirectional motor 501 drives the drive bevel gears 504 at both ends of its shaft to start rotating. When the drive bevel gears 504 rotate, they drive the driven bevel gears 505 that mesh with them to start rotating, causing the lead screw 502 to start rotating. When the lead screw 502 rotates, it drives the movable frame 503, which is threaded to it, to start moving along the guide rod 506. When the central shaft pressure head 11 contacts the housing, it drives the housing and the movable plate 402 to move synchronously towards the central shaft mounting seat 8. At this time, the spring 407 is compressed, generating a spring force in the opposite direction on the movable plate 402 until the central shaft is inserted into and passes through the central shaft mounting hole at the center of the housing shaft, thus achieving the pressing of the central shaft. At this time, the pressing mechanism 5 resets, and the movable plate 402 and the housing automatically reset under the action of the spring force, while simultaneously driving the central shaft to disengage from the central shaft mounting seat.

[0031] After the central shaft is installed, the lifting mechanism 3 drives the outer shell to move upward to the snap ring feeding mechanism 12. At this time, the snap ring is manually installed on the outside of the end of the central shaft that protrudes from the outer shell and faces the movable frame 503. The snap ring feeding mechanism can realize the automatic feeding of the snap ring. When the snap ring is fed, several snap rings sleeved on the outside of the feeding frame 1206 move towards the feeding plate 1209 under the action of gravity and fall into the inside of the feeding groove 1205. At this time, the lifting cylinder 1203 drives the top plate 1207 to move upward, lifting the snap ring inside the feeding groove 1205 until the snap ring moves upward to the inside of the picking groove 1208. At this time, the snap ring can be taken out for easy installation.

[0032] After the snap ring is installed, the lifting mechanism 3 drives the outer casing upward until it is coaxial with the bearing mounting seat 9 and stops. At this time, the ring-shaped flywheel module is installed on the end of the bearing pressure head 13 through the chuck 15, and the bearing is installed on the end of the bearing mounting seat 9. The flywheel module and the bearing are pressed onto the outer sides of both ends of the central shaft through the bearing pressure head 13. The pressing process is the same as above. After the pressing is completed, the lifting mechanism 3 drives the outer casing upward until it is coaxial with the pulley mounting seat 10 and stops. At this time, the pulley is installed at the end of the shaft of the pulley mounting seat. The pulley is pressed onto the end of the central shaft through the pulley pressure head 14. The pressing process is the same as above. This realizes the integrated assembly of the flywheel unit and effectively improves the assembly efficiency.

[0033] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
