Description

Technical Field

[0001] This utility model relates to a stator clamping and flipping device, belonging to the field of motor stator insulation processing and production technology. Background Technology

[0002] The motor manufacturing industry has always been a labor-intensive industry. Due to the special nature of its products, automated production has always been impossible. The stator end wire coating is done in a semi-automatic manner and cannot be automated. However, both semi-automatic and manual production are costly, labor-intensive, inefficient, and the quality cannot be effectively guaranteed, resulting in a low pass rate for finished products. With the current increase in labor costs and the widening gap between labor demand and supply, it is becoming increasingly difficult to meet the needs of some motor manufacturing companies.

[0003] In recent years, with the vigorous development of the automotive industry and the increasingly widespread application of various electrical products, there is a great demand for improvement in the output and quality of new energy motors. The traditional manual or semi-automatic stator end line coating process can no longer meet the requirements of product efficiency and quality. Market factors require reducing labor costs and improving production efficiency, which makes it very necessary to realize automated coating and loading / unloading. The problem of automating stator coating needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a compact, fully automated device integrating synchronous clamping, flipping, and precise locking in the stator end insulating resin powder coating process. This device can continuously complete powder coating on both ends of the stator in a single clamping operation, eliminating the need for secondary positioning or manual intervention, thus significantly improving production efficiency and operational safety. This stator clamping and flipping device, through its automated, precise, and flexible design, significantly improves coating efficiency, quality, and safety, making it a key piece of equipment in the intelligent manufacturing of motor stators.

[0005] The purpose of this utility model is achieved through the following technical solution: a stator clamping and flipping device, including a top plate and a guide rail slider mounted on the top plate. A pair of mounting brackets are mounted on the guide rail slider. Each mounting bracket is fixed with a cylinder seat and a floating joint. The cylinder body of the clamping cylinder is mounted on the cylinder seat, and the piston rod of the clamping cylinder is flexibly connected to the floating joint. Both mounting brackets are provided with connecting plate assemblies. The connecting plate assemblies are hinged to a synchronous rotating shaft fixed in the center of the top plate via a synchronous rotating plate, realizing synchronous clamping and precise guidance on both sides. Each mounting bracket is equipped with a corresponding clamping arm. A rotary servo motor and a worm gear mechanism are installed inside the clamping arm. The worm gear spindle is fixedly connected to the jaw assembly, and a protective plate is installed on the outside of the worm gear mechanism. Initially, the jaws are open and in standby mode. After the stator is in position, the clamping cylinders on both sides are vented, and the piston rod pulls the connecting plate assembly through the floating joint, driving the synchronous rotating plate to rotate around the synchronous rotating shaft, so that the mounting brackets on both sides move synchronously towards each other along the guide rail slider, and the jaw assembly clamps the stator in the center. Subsequently, the rotary servo motor starts, driving the gripper assembly through the worm gear mechanism to rotate the stator at a constant speed. This, combined with the lifting and lowering of the entire device, completes the coating operation on the other end face of the stator. After coating is completed, the motor stops, the clamping cylinder reverses its action, the mounting bracket opens synchronously, the gripper releases the stator, and the device resets to standby mode. This achieves automated coating of both end faces of the stator workpiece, ensuring the coating quality of the stator end lines.

[0006] As a preferred embodiment, a stator clamping and flipping device is provided, in which a synchronous rotating plate is hinged to a synchronous rotating shaft in the center of the top plate, linking the mounting brackets and connecting plate assemblies on both sides. Combined with the guiding action of the guide rail slider and the flexible connection between the clamping cylinder and the floating joint, it achieves symmetrical and synchronous centering clamping on both sides, while compensating for installation errors and ensuring clamping accuracy and stability. Through the linkage structure of "synchronous rotating shaft + synchronous rotating plate + double-sided connecting plate assemblies," the power of the clamping cylinders on both sides is converted into symmetrical and synchronous clamping actions. With the precise guidance of the guide rail slider, zero offset in stator centering clamping is achieved, solving the problem of coating position deviation caused by asynchronous clamping in traditional devices. Simultaneously, the flexible connection of the floating joint ensures clamping stability while compensating for installation errors, avoiding stator clamping damage, and balancing accuracy and protection.

[0007] Preferably, a stator clamping and flipping device integrates a rotary servo motor and a worm gear mechanism within its clamping arm. The worm gear spindle is directly fixed to the gripper assembly, allowing for precise control of the stator's rotation speed. The worm gear mechanism also features a self-locking function. An outer protective plate forms a protective layer for the transmission mechanism, achieving integrated clamping and rotation actions to meet coating process requirements. This innovative integrated clamping-rotation design combines the rotary servo motor, worm gear mechanism, and clamping arm. The worm gear spindle is directly fixed to the gripper assembly, simplifying the transmission chain and reducing power loss. Furthermore, the self-locking characteristic of the worm gear mechanism, combined with the precise speed control of the servo motor, prevents accidental stator movement during coating and allows for flexible speed adjustment according to the coating process. This solves the problems of motion delay and insufficient rotational accuracy caused by the separation of traditional clamping and rotation mechanisms.

[0008] The effects and benefits of this utility model are: (1) The stator clamping and flipping device described in this utility model is more accurate through double-sided synchronous clamping. Through the linkage structure of synchronous rotating plate and synchronous rotating shaft, and with the guide rail slider, it ensures that the two sides of the clamping jaws are symmetrically aligned, avoids stator offset, and ensures coating position accuracy; (2) The clamping stability is strong. The flexible connection of the floating joint can compensate for installation errors and avoid damage to the stator by clamping force. At the same time, the cylinder-driven clamping method can provide stable clamping force and prevent the stator from loosening during coating; (3) The stator clamping and flipping device described in this utility model can accurately adjust the speed through a rotary servo motor and a worm gear mechanism. The worm gear self-locking feature can prevent the stator from rotating accidentally and ensure coating uniformity. The overall structure is highly efficient and the clamping and rotation actions are smoothly connected. It meets the automation requirements of coating process, improves work efficiency, and reduces errors caused by manual intervention. Attached Figure Description

The cylinder body of a clamping cylinder 13 is mounted on the cylinder seat 12. The piston rod of the clamping cylinder 13 is flexibly connected to the floating joint 14. Both mounting brackets 11 are provided with a connecting plate assembly 4. The connecting plate assembly 4 is hinged to a synchronous rotating shaft 2 fixed in the center of the top plate 1 via a synchronous rotating plate 3 to achieve synchronous clamping and precise guidance on both sides. Each of the two mounting brackets 11 is equipped with a corresponding clamping arm 9. A rotary servo motor 6 and a worm gear mechanism 7 are installed inside the clamping arm 9. The worm gear spindle is fixedly connected to the gripper assembly 10. A protective plate 8 is installed on the outside of the worm gear mechanism 7. Initially, the grippers are open and in standby mode. After the stator is in position, the clamping cylinders 13 on both sides are vented, and the piston rod pulls the connecting plate assembly 4 through the floating joint 14, causing the synchronous rotating plate 3 to rotate around the synchronous rotating shaft 2. This causes the mounting brackets 11 on both sides to move synchronously towards each other along the guide rail slider 5, and the gripper assembly 10 clamps the stator in the center. Then, the rotary servo motor 6 starts and drives the gripper assembly 10 to rotate the stator at a uniform speed through the worm gear mechanism 7. This, combined with the lifting of the entire device, completes the coating operation on the other end face of the stator. After the coating is completed, the motor stops, the clamping cylinders 13 reverse their action, the mounting brackets 11 open synchronously, the grippers release the stator, and the device resets and goes into standby mode. This achieves automated coating on both end faces of the stator workpiece, ensuring the coating quality of the stator end lines.

[0016] Please see Figure 1 , Figure 2 and Figure 3A stator clamping and flipping device is disclosed, which hinges a synchronous rotating plate 3 to a synchronous rotating shaft 2 at the center of a top plate 1, linking the mounting brackets 11 and connecting plate assemblies 4 on both sides. Combined with the guiding action of the guide rail slider 5 and the flexible connection between the clamping cylinder 13 and the floating joint 14, it achieves symmetrical and synchronous centering clamping on both sides, while compensating for installation errors and ensuring clamping accuracy and stability. Through the linkage structure of "synchronous rotating shaft + synchronous rotating plate + double-sided connecting plate assembly," the power of the clamping cylinders 13 on both sides is converted into symmetrical and synchronous clamping action. With the precise guidance of the guide rail slider 5, zero offset in stator centering clamping is achieved, solving the problem of coating position deviation caused by asynchronous clamping in traditional devices. Simultaneously, the flexible connection of the floating joint 14 ensures clamping stability while compensating for installation errors, avoiding stator clamping damage, and balancing accuracy and protection.

[0017] Please see Figure 1 , Figure 2 and Figure 3 This utility model discloses a stator clamping and flipping device. The clamping arm 9 integrates a rotary servo motor 6 and a worm gear mechanism 7. The worm gear spindle is directly fixed to the gripper assembly 10, allowing precise control of the stator rotation speed. The worm gear mechanism 7 also features a self-locking function. An outer protective plate 8 forms a protective layer for the transmission mechanism, achieving integrated clamping and rotation actions to meet coating process requirements. This innovative integrated clamping-rotation design combines the rotary servo motor 6, the worm gear mechanism 7, and the clamping arm 9. The worm gear spindle is directly fixed to the gripper assembly 10, simplifying the transmission chain and reducing power loss. Furthermore, the self-locking characteristic of the worm gear mechanism 7, combined with the precise speed control of the servo motor, prevents accidental stator movement during coating and allows for flexible speed adjustment according to the coating process. This solves the problems of action delay and insufficient rotation accuracy caused by the separation of traditional clamping and rotation mechanisms.
