Description

Technical Field

[0001] The present invention belongs to the technical field of AC generator maintenance, and more specifically, relates to a high-adaptability production and maintenance device for an AC generator. Background Art

[0002] An AC motor is a rotating electrical machine that converts alternating current (AC) electrical energy into mechanical energy. Its operating principle is based on the laws of electromagnetic induction and electromagnetic force. It consists of two main components: a stator and a rotor. The stator typically contains an iron core and windings. When AC current is applied, it generates a rotating magnetic field. The rotor, under the action of this rotating field, generates electromagnetic torque, thereby outputting mechanical energy. AC motors can malfunction over time due to various reasons, necessitating repair.

[0003] The Chinese patent publication number is: CN118353214A, a generator maintenance device. This invention allows the generator to be surrounded by multiple limit rods to prevent the generator from slipping. At the same time, the limit rods on the left and right sides of the top of the base are connected together to facilitate the rotation of the generator driven by a motor.

[0004] Existing alternators have the following disadvantages when it comes to repairs: When replacing the coil inside the generator, manual operation is generally performed inside the generator. The internal structure of the AC generator is compact. When installing the coil in the narrow space of the shell, the operator's movement space is extremely small, and the tool operation range is limited, making it difficult to operate accurately. When fixing the coil and adjusting the position, hand movements are easily hindered, increasing the difficulty of installation. At the same time, the narrow space makes it difficult for maintenance personnel to fully observe the installation of the coil, which easily leads to problems such as incomplete installation. When installing existing generator coils, they are installed manually one by one, and the positioning, fixing, and connection operations need to be repeated many times. The process is cumbersome and installing one by one takes a lot of time. The inefficient installation method cannot meet the needs of large-scale maintenance. In emergency maintenance scenarios, it is difficult to quickly restore the generator operation and the installation is inconvenient. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a high-adaptability production and maintenance device for AC generators to solve the above problems.

When the user needs to install the coil, he can install the coil at the corresponding rubber U-shaped groove 8 position on the installation shaft 5 according to the position requirements of the coil installation. Two rubber clamping plates 84 are provided on the rubber U-shaped groove 8. The user can pry open the two rubber clamping plates 84 to deform the torsion spring 86, so that the coil bundle is stuck in the rubber U-shaped groove 8. Loosen the rubber clamping plates 84, and the torsion spring 86 will drive the rubber clamping plates 84 to reset, thereby clamping and fixing the coil. The user can perform the same operation on the rubber U-shaped groove 8 at the other end, thereby clamping and fixing the two ends of the coil bundle to complete the fixation of one coil. The user can fix the coil at other corresponding positions where the coil needs to be installed. After completing the installation and fixation of the coil, the user can insert insulating paper into each wire slot 21 in the generator housing 2 to facilitate the subsequent installation of the coil. A plurality of mounting rods 91 are fixedly installed between the gear 9 and the second disc 7. The gear 9 is rotatably installed on the circumferential end of the mounting shaft 5. The rack 4 and the gear 9 are meshed. The rotation of the gear 9 drives the second disc 7 to rotate through the mounting rod 91.

The rotation of the second disc 7 will drive each movable column 82 to move, and each movable column 82 is limited in the linear guide groove 61. Therefore, when the second disc 7 rotates, it will drive each movable column 82 to slide in the linear guide groove 61.

At this time, the user can reversely drive the electric telescopic rod 43 to extend to drive each rubber U-shaped groove 8 to slide closer to each other. At this time, after the wire groove 21 clamps the coil, the torsion spring 86 is compressed by the force to drive the rubber clamping plate 84 to open, completing the action of removing the coil and completing the installation of the coil. The user drives the cylinder 12 to extend to drive the mounting plate 3 to move, and the movement of the mounting plate 3 drives the mounting shaft 5 to leave the inner wall of the generator housing 2.

[0018] Working principle: In the first step, the AC motor can convert the electrical energy of AC power into mechanical energy. The AC motor may malfunction due to various reasons during long-term operation, and the AC motor needs to be repaired. When the coil is burned, the winding is deformed, and the inter-turn short circuit occurs, the coil in the AC motor needs to be replaced. When repairing and replacing the coil in the AC motor, the end cover of the AC motor can be removed. After removal, the burned and damaged coil inside the generator housing 2 can be taken out. After taking it out, the user can use a clamp to fix the generator housing 2 in the middle of the maintenance table 1. After the generator housing 2 is fixed, the user can fix the coil that needs to be installed in the corresponding position in the generator housing 2 on the rubber U-shaped groove 8 and the rubber clamping plate 84 according to the model of the generator housing 2 and the number of turns required for coil installation. After the fixation is completed, the cylinder 12 can be started to drive the installation shaft 5 at the side end of the installation plate 3 to enter the inner wall of the generator housing 2, and adjust the position of each rubber U-shaped groove 8 so that the coil is embedded in the wire feed groove 21, and then multiple coils can be installed simultaneously; In the second step, when the user needs to install the coil, he can install the coil at the corresponding rubber U-shaped groove 8 position on the installation shaft 5 according to the coil installation position requirements. The rubber U-shaped groove 8 is provided with two rubber clamping plates 84. The user can pry open the two rubber clamping plates 84 to deform the torsion spring 86, so that the coil bundle is stuck in the rubber U-shaped groove 8. Loosen the rubber clamping plates 84, and the torsion spring 86 will drive the rubber clamping plates 84 to reset, thereby clamping and fixing the coil. The user can perform the same operation on the rubber U-shaped groove 8 at the other end, thereby clamping and fixing the two ends of the coil bundle to complete the fixation of one coil. The user can fix the coil at other corresponding positions where the coil needs to be installed. After completing the installation and fixation of the coil, the user can insert insulating paper into each wire slot 21 in the generator housing 2 to facilitate the subsequent installation of the coil. This device is provided with a rubber U-shaped groove 8, a rubber splint 84, a rotating shaft 85 and a torsion spring 86. The torsion spring 86 provides an adaptive clamping force, which can not only fix the coil to prevent the coil from slipping or shifting during installation, but also automatically release the coil due to the force after being embedded in the wire groove 21, thereby achieving fast unloading without jamming and reducing manual intervention. The surface of the rubber U-shaped groove 8 and the rubber splint 84 has good anti-slip properties and flexibility, which ensures that the coil is firmly clamped by increasing friction, and can provide buffering performance to prevent the coil insulation layer from being pinched. The third step, after completing the fixation and installation of the coil, the user can embed the coil into the wire groove 21, the user can start the cylinder 12, the cylinder 12 contracts and drives the L-shaped slide bar 31 to slide in the guide rail 11, driving the mounting plate 3 to move toward one side of the generator housing 2, and the movement of the mounting plate 3 drives the mounting shaft 5 to move. When the mounting shaft 5 moves into the generator housing 2, the mounting shaft 5 will drive the first disc 6, the second disc 7 and the coil on the rubber U-shaped groove 8 to enter the generator housing 2. When the moving mounting shaft 5 drives the rubber U-shaped grooves 8 on both sides to be located on both sides of the generator housing 2, the coil is located on the inner side wall of the generator housing 2. After moving to the appropriate installation position, the user can close the cylinder 12. At this time, the user can start the electric telescopic rod 43. When the electric telescopic rod 43 contracts, it will drive the rack 4 to move upward. The upward movement of the rack 4 will drive the gear 9 to rotate. The rotation of the gear 9 drives the second disc 7 to rotate through the mounting rod 91. The rotation of the second disc 7 on one side will pass through the cylindrical rod 72 The second disc 7 on the other side is driven to rotate. The rotation of the second disc 7 will drive each movable post 82 to move, and each movable post 82 is limited in the linear guide groove 61. Therefore, when the second disc 7 rotates, it will drive each movable post 82 to slide in the linear guide groove 61. The movement of the movable post 82 will drive each push rod 81 to move. The movement of each push rod 81 will drive each rubber U-shaped groove 8 to move away from each other. The movement of each rubber U-shaped groove 8 will drive each coil to move closer to the position of the wire groove 21, until the rubber U-shaped groove 8 drives each coil to be embedded in the wire groove 21, completing the installation and embedding of the coil. At this time, the user can reversely drive the electric telescopic rod 43 to extend and drive each rubber U-shaped groove 8 to slide closer to each other. At this time, after the wire groove 21 clamps the coil, the torsion spring 86 is compressed by the force and drives the rubber clamping plate 84 to open, completing the action of removing the coil and completing the installation of the coil. The user drives the cylinder 12 to extend and drive the mounting plate 3 to move. The movement of the mounting plate 3 drives the mounting shaft 5 to leave the inner wall of the generator housing 2. This device, by providing a rubber U-shaped groove 8 and a rubber clamping plate 84, transfers the coil fixing link to the spacious area outside the generator housing 2, avoiding the inconvenience of installing the coil due to the narrow space inside the generator housing 2 when operating inside the generator housing 2. The pre-fixing method can also reduce the steps of frequent adjustment of the coil inside the generator housing 2, reduce installation errors caused by space constraints, and greatly improve installation efficiency and convenience. The device is provided with a second disc 7 and a first disc 6 to cooperate with each other. The rotation of the second disc 7 drives each rubber U-shaped groove 8 to move synchronously, so that the coil is embedded in the wire groove 21, so that all coils are synchronously and uniformly fed into the wire groove 21, thereby avoiding uneven electromagnetic performance caused by differences in installation sequence. There is no need to install and adjust the coils one by one, thereby improving the installation efficiency of the coils when the generator housing 2 is being repaired, and quickly facilitating the synchronous installation of multiple coils. The device is provided with an adjustable rubber U-shaped groove 8, a push rod 81 and a movable column 82. When the first disc 6 rotates, the rubber U-shaped groove 8 can be driven to embed the coil into the wire groove 21. When the coil is installed, the device can adapt to generator housings 2 of different sizes, slot numbers and winding layouts for repair and coil replacement, and has higher adaptability and flexibility. This device ensures that the moving path of each coil during installation is consistent with the final position by setting the second disc 7, the first disc 6 and the rubber U-shaped groove 8, avoiding problems such as three-phase imbalance and winding misalignment caused by installation errors, ensuring that the position amplitude of each coil movement remains the same, ensuring stable and accurate installation, facilitating subsequent operations such as re-grooving by operators, and improving the installation efficiency of the coil.
