Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a fixing bracket for electrophoresis of motor stator. Background Technology

[0002] As a core component of an electric motor, the quality and stability of the motor stator directly affect the overall performance and service life of the motor. During motor manufacturing, electrophoretic coating has become an indispensable process to enhance the corrosion resistance and aesthetics of the motor stator. Electrophoretic coating not only provides a uniform coating but also ensures a strong bond between the coating and the substrate, thereby improving the durability of the motor stator.

[0003] However, in the electrophoretic coating process of motor stators, the design and performance of the mounting bracket, as a key device for connecting and supporting the motor stator, are particularly important. The motor stator needs to be stably connected via the mounting bracket during electrophoretic coating to ensure stability and uniformity during the coating process. However, existing mounting brackets are not ideal in their design for limiting the movement of the motor stator, which causes the stator to easily wobble on the bracket, thus affecting the accuracy of the electrophoretic coating and the coating quality.

[0004] Specifically, existing mounting brackets, due to inadequate limiting structures or insufficient tightening force, make it difficult to maintain stability of the motor stator during the coating process. This wobbling not only leads to uneven coating thickness and defects, but may also cause the motor stator to collide with the tank walls or other stators within the coating tank, resulting in surface damage or coating peeling. More seriously, wobbling can also affect the overall efficiency of electrophoretic coating, increase rework rates and production costs, and simultaneously reduce the overall quality and safety of the motor.

[0005] Therefore, given the significant problems of existing fixing brackets in the electrophoretic coating process of motor stators, such as poor limiting effect and easy shaking, we urgently need a fixing bracket for electrophoretic coating of motor stators. This fixing bracket should significantly improve the stability of the motor stator during the coating process, ensuring uniform coating and reliable quality. Utility Model Content

[0006] The purpose of this invention is to provide a fixing bracket for electrophoresis of motor stators, which solves the problem that the existing fixing brackets in the prior art are not ideal in terms of limiting the motor stator, which causes the motor stator to shake easily on the fixing bracket, thus affecting the accuracy of electrophoretic coating and the coating quality.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A mounting bracket for electrophoresis of motor stators includes a lifting bracket and several motor stators;

[0009] The bottom of the hoisting bracket is provided with a connecting rod, and the bottom end of each connecting rod can be detachably connected to a support plate for supporting the motor stator. The top of the support plate is provided with a limiting cone, and the limiting cone is connected to the top of the support plate by a fastening structure.

[0010] Preferably, the diameter of the end of the limiting cone near the support plate is smaller than the diameter of the other end, and the diameter of the top part of the limiting cone is smaller than the outer diameter of the motor stator.

[0011] Preferably, a connecting rod is fixedly connected at the top center of the support plate, one end of which is detachably connected to the end of the docking rod, and a circular hole adapted to slide and engage with the connecting rod is provided at the center of the limiting cone.

[0012] Preferably, the fastening structure includes two round rods that pass through the top of the limiting cone via bushings. The bottom ends of the two round rods are fixedly connected to limiting screws, and the top ends of the two round rods are fixedly connected to handles. The top of the support plate has two screw holes that are adapted to the limiting screws.

[0013] Preferably, a plurality of supporting rods are fixedly connected to the top edge of the supporting plate, and the plurality of supporting rods are arranged in a ring along the circumference of the supporting plate.

[0014] Preferably, the bottom end of the connecting rod is fixedly connected to a connecting sleeve for mating with the connecting rod, and the connecting sleeve and the connecting rod are connected by a positioning screw.

[0015] This utility model has at least the following beneficial effects:

[0016] This utility model discloses a fixing bracket for electrophoretic coating of motor stators, which significantly improves the stability and efficiency of the electrophoretic coating process. On one hand, the detachable connection design of the lifting bracket, connecting rod, and support plate, along with the precise limiting function of the upper limit cone on the support plate, effectively solves the technical problem of easy shaking and displacement of the motor stator during coating, ensuring the motor stator remains stationary during the coating process, thereby improving the uniformity and quality of the coating.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5 As shown, a fixing frame for electrophoresis of motor stators in this embodiment includes a hoisting bracket 4 and several motor stators 1;

[0027] Lifting bracket 4: Serving as the supporting foundation for the entire fixture, lifting bracket 4 is stably suspended from the electrophoretic coating line using appropriate lifting equipment, providing reliable suspension support for the motor stator 1 below. Its robust structure ensures the stability and safety of the entire fixture during the electrophoretic coating process.

[0028] Connecting rod 3: The connecting rod 3 is located at the bottom of the lifting bracket 4 and is an important component connecting the lifting bracket 4 and the support plate 7. Through the connecting rod 3, the support plate 7 can be detachably connected to the bottom of the lifting bracket 4, which facilitates flexible adjustment according to the number and size of the motor stator 1.

[0029] Support plate 7: Support plate 7 is the direct load-bearing component of motor stator 1, and its top is designed to stably place motor stator 1. Support plate 7 is connected to the bottom end of docking rod 3 by a detachable connection, ensuring stable support for motor stator 1, while facilitating replacement or adjustment to accommodate motor stators of different sizes.

[0030] Limiting cone 8: The limiting cone 8 is located on the top of the support plate 7 and is a key component for the precise positioning and limiting of the motor stator 1. Its conical design allows the limiting cone 8 to be easily inserted into the inner hole of the motor stator 1, and due to its gradually increasing diameter, it achieves a stable limiting of the motor stator 1, preventing shaking or displacement during the electrophoretic coating process.

[0031] Fastening structure: The fastening structure is an important component connecting the limiting cone 8 and the support plate 7, ensuring that the limiting cone 8 will not loosen or fall off during the painting process. Through the fastening structure, the limiting cone 8 can be stably fixed on the support plate 7, providing reliable limiting support for the motor stator 1.

[0032] The bottom of the hoisting bracket 4 is provided with a connecting rod 3. The bottom end of each connecting rod 3 can be detachably connected to a support plate 7 for supporting the motor stator 1. The top of the support plate 7 is provided with a limiting cone 8, which is connected to the top of the support plate 7 by a fastening structure.

[0033] Example 2

[0034] Please see Figure 1-5 As shown in this embodiment, a fixing bracket for electrophoresis of a motor stator has a limiting cone 8 whose diameter at one end near the support plate 7 is smaller than the diameter at the other end, and the diameter at the top of the limiting cone 8 is smaller than the outer diameter of the motor stator 1. Specifically, by setting the diameter of the limiting cone 8 at one end near the support plate 7 to be smaller than the diameter at the other end, and the diameter at the top of the limiting cone 8 to be smaller than the outer diameter of the motor stator 1, after the motor stator 1 is placed on the support plate 7, the limiting cone 8 can easily be inserted into the inner hole of the motor stator 1. Due to its tapered design, the diameter increases towards the bottom, thereby achieving a stable limiting of the motor stator 1. This design not only simplifies the positioning process but also enhances the stability of the motor stator on the fixing bracket, achieving the effect of precise limiting and preventing shaking.

[0035] The fastening structure includes two round rods 12 that pass through the top of the limiting cone 8 via bushings. The bottom ends of both round rods 12 are fixedly connected to limiting screws 11, and the top ends of both round rods 12 are fixedly connected to handles 14. The top of the support plate 7 has two screw holes adapted to the limiting screws 11. Specifically, by including the two round rods 12 that pass through the top of the limiting cone 8 via bushings, the bottom ends of both round rods 12 are fixedly connected to limiting screws 11, and the top of the support plate 7 has two screw holes adapted to the limiting screws 11, after the limiting cone 8 is adjusted to the appropriate position, rotating the handles 14 causes the round rods 12 and the limiting screws 11 to rotate, causing the limiting screws 11 to screw into the screw holes of the support plate 7, thereby fastening the limiting cone 8. This design ensures that the limiting cone 8 will not loosen or fall off during the painting process, achieving a stable fixation and enhanced safety.

[0036] Example 3

[0037] Please see Figure 1-5 As shown in this embodiment, a fixing bracket for electrophoresis of a motor stator has a connecting rod 2 fixedly connected to the top center of a support plate 7, one end of which is detachably connected to the end of a docking rod 3. A circular hole 13, adapted to slide and engage with the connecting rod 2, is provided at the center of a limiting cone 8. Specifically, by fixing the connecting rod 2, one end of which is detachably connected to the end of the docking rod 3, at the top center of the support plate 7, and by providing a circular hole 13 at the center of the limiting cone 8, adapted to slide and engage with the connecting rod 2, after the connecting rod 2 is connected to the docking rod 3, the limiting cone 8 can slide up and down along the connecting rod 2 and adjust its position, allowing the limiting cone 8 to more accurately adapt to motor stators 1 of different sizes. This design improves the versatility and flexibility of the fixing bracket, achieving the effect of adapting to motor stators of various sizes and expanding its application range.

[0038] A connecting sleeve 5 is fixedly connected to the bottom end of the connecting rod 3 for mating with the connecting rod 2. The connecting sleeve 5 and the connecting rod 2 are connected by a positioning screw 6. Specifically, the connection of the connecting sleeve 5 to the bottom end of the connecting rod 3 and the positioning screw 6 allows for a secure connection between the connecting rod 2 and the connecting rod 3 after the connecting rod 2 is inserted into the connecting sleeve 5. This design not only simplifies the connection process but also improves the reliability and stability of the connection, achieving the effects of easy installation and disassembly and increased connection strength.

[0039] Several supporting rods 10 are fixedly connected to the top edge of the support plate 7. These supporting rods 10 are arranged in a circular array along the circumference of the support plate 7. Specifically, by fixing several supporting rods 10 to the top edge of the support plate 7 and arranging them in a circular array along the circumference of the support plate 7, the supporting rods 10 can provide additional support points for the motor stator 1, further enhancing the stability of the motor stator on the support plate 7. At the same time, the circular array design makes the supporting force more evenly distributed, achieving the effect of improving support stability and preventing deformation of the motor stator.

[0040] This solution includes the following work process:

[0041] The lifting bracket 4 is securely and horizontally suspended at the designated position on the electrophoretic coating line using appropriate lifting equipment. This step ensures the stability of the entire mounting base, providing reliable support for the subsequent fixing and coating of the motor stator 1.

[0042] Next, the motor stator 1 is placed on the support plate 7 through the connecting rod 2. At this point, the design of the limiting cone 8 plays a crucial role. The diameter of the limiting cone 8 at the end near the support plate 7 is smaller than the diameter at the other end, and the diameter of the top end is smaller than the outer diameter of the motor stator 1. This design allows the limiting cone 8 to be easily inserted into the inner hole of the motor stator 1, and due to its tapered design, the diameter increases towards the bottom, thus achieving a stable positioning of the motor stator 1. This design not only simplifies the positioning process but also effectively prevents the motor stator 1 from shaking during the coating process, improving the uniformity and quality of the coating.

[0043] Furthermore, a connecting rod 2, one end of which is detachably connected to the end of the docking rod 3, is fixedly connected to the top center of the support plate 7, while a circular hole 13, adapted to slide and engage with the connecting rod 2, is provided at the center of the limiting cone 8. This design allows the limiting cone 8 to slide up and down along the connecting rod 2 and adjust its position to engage with the top of the motor stator 1. This increased versatility and flexibility greatly expands the application range of the mounting bracket.

[0044] To ensure that the limiting cone 8 does not loosen or fall off during the painting process, this technical solution also includes a fastening structure. This structure comprises two round rods 12 that pass through the top of the limiting cone 8 via bushings. The bottom ends of both round rods 12 are fixedly connected to limiting screws 11, while the top of the support plate 7 has two screw holes that mate with the limiting screws 11. After the limiting cone 8 is adjusted to the appropriate position, rotating the handle 14 rotates the round rods 12 and the limiting screws 11, causing the limiting screws 11 to screw into the screw holes of the support plate 7, thereby fastening the limiting cone 8. This design greatly enhances the safety and stability of the mounting bracket.

[0045] In addition, several support rods 10 are fixedly connected to the top edge of the support plate 7, and these support rods 10 are arranged in a ring array along the circumference of the support plate 7. The support rods 10 provide additional support points for the motor stator 1, further enhancing its stability on the support plate 7. At the same time, the ring array design makes the supporting force more evenly distributed, effectively preventing deformation of the motor stator 1.

[0046] Finally, a connecting sleeve 5 is fixedly connected to the bottom end of the connecting rod 3 for mating with the connecting rod 2. The connecting sleeve 5 and the connecting rod 2 are connected by a positioning screw 6. This design simplifies the connection process, improves the reliability and stability of the connection, and makes the installation and disassembly of the entire fixing frame more convenient and quick.

[0047] In summary, the fixing bracket for electrophoresis of motor stators provided by this technical solution achieves limiting, stable support, and reliable fixing of the motor stator 1, thereby improving the efficiency and quality of electrophoretic coating.
