[0020] The embodiments of this utility model application will be described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model application, but should not be used to limit the scope of this utility model application. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model application.

[0021] CombinationFigure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a universal assembly line for automatic assembly of automotive generator rotors includes an assembly line base plate 1, a connecting plate 2 on the assembly line base plate 1, a claw pole positioning seat 3 for fixing the motor rotor at the center of the connecting plate 2, clamping mechanisms 4 for clamping and fixing the motor claw poles on both sides of the claw pole positioning seat 3, and a positioning mechanism 5 for positioning the motor claw poles on the clamping mechanism 4.

[0022] This utility model proposes a universal assembly line plate for automatic assembly of automotive generator rotors. The assembly line plate base plate 1 is the basic support component of the entire universal assembly line plate for automatic assembly of automotive generator rotors, providing an installation platform for other components, ensuring the stability and integrity of the entire assembly line plate structure, and enabling various components to be rationally arranged and work together on it.

[0023] Connecting plate 2 is mounted on the bottom plate 1 of the flow board, serving as a connection and transition. The positions and layouts of other components are adjusted and adapted according to actual assembly requirements.

[0024] The claw pole positioning seat 3 is located at the center of the connecting plate 2 and is a key component specifically used to fix the motor rotor. The claw pole positioning seat 3 matches the shape and size of the motor rotor, and can accurately position the motor rotor in a specific position, providing a precise reference for subsequent assembly operations, ensuring the positional accuracy and stability of the motor rotor during the assembly process, thereby ensuring assembly quality.

[0025] The clamping mechanism 4 is located on both sides of the claw pole positioning seat 3, and its main function is to clamp and fix the motor claw pole. The clamping mechanism 4 ensures that the motor claw pole will not shift or loosen during the assembly process, and at the same time, it also avoids damage to the motor claw pole due to excessive clamping force.

[0026] The positioning mechanism 5 is mounted on the clamping mechanism 4 and is used to position the motor claw poles. The positioning mechanism 5 further ensures the accuracy of the motor claw poles' position during clamping. It cooperates with the claw pole positioning seat 3 to position the motor claw poles from different angles and directions, ensuring that the motor claw poles can dock with other components during assembly, thus improving assembly accuracy and efficiency. The positioning mechanism 5 may include components such as positioning pins and positioning blocks, which, through cooperation with corresponding structures on the motor claw poles, achieve precise positioning.

[0027] In the automated assembly process of the automotive generator rotor, the motor rotor is first placed on the claw pole positioning seat 3. The claw pole positioning seat 3 performs preliminary positioning of the motor rotor, determining its approximate position on the assembly board. Then, the clamping mechanism 4 begins to operate, moving closer to the motor claw poles under the action of the drive device to clamp and fix them, ensuring that the motor claw poles will not move during assembly. Simultaneously, the positioning mechanism 5 mounted on the clamping mechanism 4 functions, cooperating with the positioning structure on the motor claw poles to precisely position them, further ensuring the positional accuracy of the motor claw poles. In this way, both the motor rotor and the motor claw poles are accurately positioned and fixed on the assembly board, providing a good foundation for subsequent assembly processes and ensuring that the entire assembly process of the automotive generator rotor proceeds smoothly and that the assembly quality meets the requirements.

[0028] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping mechanism 4 includes push-pull blocks 41 symmetrically arranged on both sides of the claw pole positioning seat 3.

[0029] Specifically, push-pull blocks 41 are symmetrically arranged on both sides of the claw pole positioning seat 3. This symmetrical arrangement allows the push-pull blocks 41 to apply force to the motor claw pole from two opposite directions, thereby achieving a uniform and stable clamping effect. The push-pull blocks 41 themselves may have a certain shape and size to adapt to the shape of the motor claw pole, ensuring full contact with the motor claw pole during clamping and providing sufficient clamping force. At the same time, the push-pull blocks 41 may also have an interface or structure for connecting to the drive device, so as to realize the push-pull action under the action of the drive device.

[0030] During the automatic assembly of the automotive generator rotor, the drive unit activates when the motor claw poles need to be clamped and fixed. The drive unit applies a force to the push-pull blocks 41, causing the symmetrically arranged blocks 41 on both sides of the claw pole positioning seat 3 to move towards the motor claw poles. As the push-pull blocks 41 move, they gradually contact the motor claw poles and apply clamping force. Because the push-pull blocks 41 are symmetrically arranged, applying force to the motor claw poles from two opposite directions ensures that the motor claw poles are subjected to a uniform clamping force, thus being stably fixed near the claw pole positioning seat 3. After assembly, the drive unit activates again, causing the push-pull blocks 41 to move away from the motor claw poles, releasing the clamping force to facilitate subsequent operations or removal of the assembled components. Through this symmetrical push-pull action of the push-pull blocks 41, the clamping mechanism 4 can effectively clamp and release the motor claw poles, meeting the requirements of automatic assembly of the automotive generator rotor.

[0031] CombinationFigure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a tension spring 6 is connected to one side of each of the two push-pull blocks 41, and two opposing gear racks 7 are connected to the other side of each of the two push-pull blocks 41. Gears 8 are meshed on the gear racks 7, and the rotation shaft of the gears 8 is connected to one side of the claw pole positioning seat 3.

[0032] Specifically, there are two push-pull blocks 41, symmetrically arranged on both sides of the claw pole positioning seat 3. These are the components in the clamping mechanism 4 that directly contact the motor claw pole and apply clamping force. Their shape and size design must adapt to the shape of the motor claw pole to ensure the stability and effectiveness of clamping.

[0033] A tension spring 6 is connected to one side of the two push-pull blocks 41. The tension spring 6 is elastic and can deform when subjected to external force and return to its original shape after the external force is removed. This characteristic is used to provide a reset or auxiliary clamping force for the push-pull blocks 41.

[0034] Two opposing gear racks 7 are connected to the other side of each of the two push-pull blocks 41. The gear racks 7 have teeth that can mesh with the gears 8 to convert the linear motion of the push-pull blocks 41 into the rotational motion of the gears 8, or to convert the rotational motion of the gears 8 into the linear motion of the push-pull blocks 41.

[0035] Gear 8 meshes with rack 7, and its rotation axis is connected to one side of claw pole positioning seat 3. Gear 8 can rotate around the rotation axis under the drive of rack 7, and can also drive rack 7 to move through its own rotation, thereby realizing the movement of push-pull block 41.

[0036] When it is necessary to clamp the motor claw pole, the external drive device acts on one of the push-pull blocks 41, causing it to move closer to the motor claw pole. Since the two push-pull blocks 41 are interconnected through a gear rack 7 and a gear 8, when the left push-pull block 41 moves, it drives the gear rack 7 connected to it to move, and the gear rack 7 drives the gear 8 to rotate. After the gear 8 rotates, it drives the other gear rack 7 that meshes with it to move, which in turn pushes the right push-pull block 41 to also move closer to the motor claw pole. During this process, the tension spring 6 is stretched, generating elastic potential energy. As the two push-pull blocks 41 move closer to the motor claw pole at the same time, they gradually apply a clamping force to the motor claw pole, stably fixing it near the claw pole positioning seat 3.

[0037] When assembly is complete and the motor claw poles need to be released, the external drive device stops applying force to the push-pull blocks 41. At this time, the tension spring 6 releases its elastic potential energy, generating a restoring force that pulls the two push-pull blocks 41 away from the motor claw poles. The movement of the push-pull blocks 41 drives the gear rack 7 to move, which in turn drives the gear 8 to rotate in the opposite direction, thereby causing the two push-pull blocks 41 to simultaneously release the motor claw poles, completing the release operation.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the claw positioning seat 3 has a circular structure. Semi-circular grooves 31 are provided on both sides of the claw positioning seat 3. The front end of the push-pull block 41 is provided with a protrusion 411 that matches the semi-circular groove 31. A replaceable lever 413 is provided at the circular part of the protrusion 411.

[0039] Specifically, the claw pole positioning seat 3 has an overall circular structure to match the shape of the motor rotor and provide a stable positioning base for the motor rotor. Semi-circular grooves 31 are symmetrically provided on both sides of the claw pole positioning seat 3. The shape and size of the semi-circular grooves 31 are determined according to the shape and size of the relevant parts of the motor claw pole, and their function is to provide positioning and guidance for subsequent cooperation with the push-pull block 41.

[0040] The front end of the push-pull block 41 is provided with a protrusion 411 that matches the semi-circular grooves 31 on both sides of the claw pole positioning seat 3. The shape and size of the protrusion 411 precisely correspond to the semi-circular grooves 31. When the push-pull block 41 moves, the protrusion 411 can accurately fit into the semi-circular grooves 31, achieving precise docking between the push-pull block 41 and the claw pole positioning seat 3, thereby ensuring accurate clamping position of the motor claw pole. A replaceable lever 413 is provided at the circular part of the protrusion 411. The design of the lever 413 is likely to better contact the motor claw pole during clamping, providing a suitable clamping action point. The replaceable feature allows for easy replacement when the lever 413 is worn or damaged, reducing maintenance costs.

[0041] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism 5 includes a positioning post 51 disposed at the front end of the push-pull block 41.

[0042] Specifically, the positioning post 51 is located at the front end of the push-pull block 41. The shape, size, and position of the positioning post 51 must match the corresponding positioning structure on the motor claw pole. For example, the motor claw pole may have positioning holes or positioning grooves that fit the positioning post 51. The positioning post 51 is designed to not deform during the positioning process, thereby ensuring the accuracy of the positioning.

[0043] Before the automatic assembly of the automotive generator rotor begins, the push-pull block 41 is in its initial position, and the positioning post 51 has not yet contacted the motor claw pole. When positioning of the motor claw pole is required, the push-pull block 41 moves towards the motor claw pole under the action of the drive device. As the push-pull block 41 moves, the positioning post 51 located at its front end gradually approaches the motor claw pole. When the positioning post 51 reaches the corresponding positioning structure on the motor claw pole, it inserts into that positioning structure. Since the positioning post 51 matches the positioning structure on the motor claw pole, the insertion of the positioning post 51 can accurately restrict the movement of the motor claw pole in a specific direction, thereby achieving the positioning of the motor claw pole. This ensures that the relative position of the motor claw pole with other components is accurate during subsequent assembly, providing a guarantee for high-quality assembly.

[0044] After positioning is completed, the positioning post 51 maintains its positioning function on the motor claw pole throughout the entire clamping and assembly process until the assembly is completed. Then, the push-pull block 41 moves in the opposite direction, the positioning post 51 exits from the positioning structure of the motor claw pole, and the motor claw pole is released.

[0045] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a sliding groove 11 is provided on the bottom plate 1 of the flow plate, and the bottom of the positioning column 51 is slidably connected to the sliding groove 11.

[0046] Specifically, the sliding groove 11 is formed on the bottom plate 1 of the flow plate and is designed according to the bottom structure of the positioning column 51 to ensure that the positioning column 51 can slide smoothly in it.

[0047] The positioning post 51 is located at the front end of the push-pull block 41 and is used to position the motor claw pole. The bottom of the positioning post 51 is slidably connected to the sliding groove 11, so that the positioning post 51 can move in a specific direction within the sliding groove 11, while maintaining its relative positional relationship with the bottom plate 1 of the flow plate, ensuring the stability and accuracy of the positioning post 51 during movement.

[0048] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a linear guide rail 21 is provided on the connecting plate 2, and a slider 412 matching the linear guide rail 21 is provided at the bottom of the push-pull block 41.

[0049] Specifically, the linear guide 21 is mounted on the connecting plate 2. The linear guide 21 is a guide component with high precision, high rigidity, and low friction characteristics. The orientation of the linear guide 21 determines the movement direction of the push-pull block 41, providing precise guidance for the linear movement of the push-pull block 41.

[0050] The bottom of the push-pull block 41 is equipped with a slider 412 that matches the linear guide rail 21. The internal structure of the slider 412 is adapted to the shape of the linear guide rail 21, and it typically contacts the linear guide rail 21 by rolling or sliding to reduce frictional resistance and improve the flexibility and accuracy of movement. The slider 412 can be fixed to the bottom of the push-pull block 41 by bolts or other connection methods to ensure a firm and reliable connection between the two.

[0051] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, bolt holes 9 for fixing the assembly plate 1 are provided around its perimeter. Specifically, the assembly plate 1 is the basic load-bearing component of the universal assembly plate for automatic assembly of automotive generator rotors, providing an installation and support platform for other components on the assembly plate, ensuring the stability and reliability of the overall structure of the assembly plate. The assembly plate 1 is usually made of materials with a certain strength and rigidity, such as steel or aluminum alloy, to withstand various forces and vibrations generated during the assembly process.

[0052] Bolt holes 9 are formed around the perimeter of the base plate 1 of the flow plate, and their number depends on the actual fixing requirements, generally arranged symmetrically. The diameter of the bolt holes 9 matches the specifications of the selected bolts, and their depth and wall quality are carefully designed and machined to ensure that the bolts can be securely installed. The inner wall of the bolt holes 9 usually has a smooth surface to facilitate the smooth screwing of the bolts.

[0053] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
