Description

Technical Field

[0001] This utility model relates to the technical field of stator assembly impregnation equipment, specifically to a stator assembly impregnation equipment for motor production. Background Technology

[0002] In the motor manufacturing process, the stator assembly impregnation process is a crucial step. Traditional stator assembly impregnation equipment often has many shortcomings.

[0003] In terms of impregnation efficiency, most traditional devices can only impregnate a single stator, and the stator's position in the varnish is relatively fixed. Impregnation relies solely on the natural flow and diffusion of the varnish, making the process extremely slow. The varnish cannot penetrate sufficiently and quickly to all parts of the stator, often resulting in uneven impregnation, with some areas having excessively thin or thick varnish layers. This severely affects the stator's insulation performance and overall quality, thereby reducing the motor's performance and lifespan.

[0004] Traditional designs lack effective solutions for cleaning and maintaining dipping equipment. During the dipping process, paint easily adheres to the inner wall of the dipping container. Over time, this adhered paint gradually accumulates and dries, not only causing significant paint waste and increasing production costs, but also polluting the dipping environment and affecting the normal operation of subsequent dipping operations. After each dipping operation, a large amount of manpower and time is required to clean the dipping container, which undoubtedly increases labor costs and equipment downtime, reducing production efficiency.

[0005] Furthermore, traditional stator impregnation equipment is not convenient or precise enough in terms of stator installation and positioning. The stator's height is difficult to adjust precisely, potentially preventing the achievement of optimal impregnation depth and affecting the impregnation effect. Moreover, the equipment has poor adaptability to stators of different sizes, often requiring complex adjustments or component replacements, making operation cumbersome and further reducing production efficiency while increasing production difficulty and cost. In summary, existing stator assembly impregnation equipment has significant shortcomings in impregnation efficiency, cleaning and maintenance, and stator installation and positioning, urgently requiring a more efficient, convenient, and multifunctional impregnation device to meet the needs of motor production. Utility Model Content

[0006] The purpose of this invention is to provide a stator assembly impregnation device for motor production, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A stator assembly impregnation device for motor production includes an impregnation box and a stator body. The side of the impregnation box is provided with a lifting assembly for adjusting the height of the stator body. The lifting assembly includes a support base and a hydraulic rod.

[0009] A positioning frame is fixedly connected to the top of the hydraulic rod. A limiting groove is opened on one side of the positioning frame. A stator mounting rod is engaged with the inner wall of the limiting groove. The stator body is sleeved on the outer wall of the stator mounting rod.

[0010] One end of the support base is provided with a threaded groove, and a threaded rod is threadedly connected to the inner wall of the threaded groove. One end of the threaded rod is fixedly connected to a drive motor, and scraper rods are provided on both sides of the positioning frame.

[0011] A further improvement of this utility model is that the scraper bar is fixedly connected to one side of the positioning frame via a fixing rod on the side near the top.

[0012] A further improvement of this utility model is that: the outer wall of the scraper is fitted with a wear-resistant sleeve, and the scraper is used to scrape off the paint liquid from the inner wall of the paint dipping box.

[0013] A further improvement of this utility model is that positioning rings are fixedly connected to the outer walls of the stator mounting rod near both ends.

[0014] A further improvement of this utility model is that: a transverse groove is provided on the side of the varnish-impregnation box for guiding the movement of the support base block, and one side of the support base block is slidably connected to the inner wall of the transverse groove by a slider.

[0015] A further improvement of this utility model is that a guide slide is provided on the side of the varnish-impregnating box away from the threaded rod.

[0016] A further improvement of this utility model is that a spring telescopic rod is fixedly connected to the upper surface of the supporting base block, and the top end of the spring telescopic rod is fixedly connected to the bottom surface of the positioning frame.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides a stator assembly impregnation device for motor production, which possesses an excellent impregnation efficiency enhancement mechanism. During the impregnation process, the drive motor plays a crucial role, rotating the threaded rod. This rotational motion is precisely transmitted to the support block, causing it to move laterally in a specific direction. Because the support block is tightly connected to the positioning frame, which in turn supports the stator mounting rod and the stator body, the stator body can achieve stable lateral movement within the impregnation chamber. More ingeniously, the device supports the reciprocating movement of the stator body, a design that greatly enhances the interaction between the stator body and the varnish. In this way, the varnish can impregnate the outer wall of the stator body more quickly and comprehensively, effectively eliminating impregnation dead zones and significantly ensuring impregnation quality and uniformity. Simultaneously, the device can accommodate multiple stator bodies for simultaneous impregnation operations. This feature is particularly important in large-scale motor production scenarios, greatly improving overall production efficiency, reducing production cycles, and providing strong support for efficient production in enterprises.

[0019] 2. This utility model provides a stator assembly impregnation device for motor production. Scrapers are cleverly designed on both sides of the positioning frame of the device. During the impregnation process, the scrapers play an indispensable automatic cleaning role. When the positioning frame moves laterally, the scrapers move synchronously, and the wear-resistant sleeve fitted onto the outer wall of the scraper makes close contact with the inner wall of the impregnation box. During this process, the wear-resistant sleeve, with its excellent wear resistance and fit, effectively scrapes away the paint adhering to the inner wall of the impregnation box. Furthermore, because the scraper can perform reciprocating scraping motion, this movement mode ensures that every corner of the inner wall of the impregnation box is thoroughly cleaned, leaving no cleaning dead spots. This automatic cleaning function brings several advantages. On the one hand, it significantly reduces paint residue on the inner wall of the impregnation box, avoiding paint waste and reducing production costs. On the other hand, maintaining the cleanliness of the impregnation box helps subsequent impregnation work to always be carried out in a good environment, reducing quality problems caused by paint residue and improving product consistency and stability. In addition, the automatic cleaning function greatly reduces the frequency and labor intensity of manual cleaning, saves human resources, improves the overall maintenance convenience of the equipment, enables the equipment to operate stably for a long time, and reduces production delays caused by maintenance downtime.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Example 1

[0028] like Figure 1-4 As shown, this utility model provides a stator assembly impregnation device for motor production, including an impregnation box 1 and a stator body 5. The side of the impregnation box 1 is provided with a lifting component 4 for adjusting the height of the stator body 5. The lifting component 4 includes a support base block 7 and a hydraulic rod 8.

[0029] A positioning frame 6 is fixedly connected to the top of the hydraulic rod 8. A limiting groove 12 is opened on one side of the positioning frame 6. A stator mounting rod 10 is engaged with the inner wall of the limiting groove 12. The stator body 5 is sleeved on the outer wall of the stator mounting rod 10.

[0030] One end of the support base block 7 is provided with a threaded groove 15, and a threaded rod 3 is threadedly connected to the inner wall of the threaded groove 15. One end of the threaded rod 3 is fixedly connected to a drive motor 2, and scraper rods 11 are provided on both sides of the positioning frame 6.

[0031] The scraper 11 is fixedly connected to one side of the positioning frame 6 via a fixing rod on the side near the top.

[0032] The outer wall of the scraper 11 is fitted with a wear-resistant sleeve 14, and the scraper 11 is used to scrape off the paint liquid from the inner wall of the paint dipping box 1.

[0033] Example 2

[0034] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, positioning rings 13 are fixedly connected to the outer walls of the stator mounting rod 10 near both ends.

[0035] The side of the varnish-impregnation box 1 is provided with a transverse groove for guiding the movement of the support base 7. One side of the support base 7 is slidably connected to the inner wall of the transverse groove by a slider.

[0036] A guide slide is provided on the side of the varnish-impregnating box 1 away from the threaded rod 3.

[0037] A spring telescopic rod 9 is fixedly connected to the upper surface of the support block 7, and the top end of the spring telescopic rod 9 is fixedly connected to the bottom surface of the positioning frame 6.

[0038] The working principle of the stator assembly impregnation device used in the production of this motor will be explained in detail below.

[0039] like Figure 1-4 As shown, in use, after installing the stator body 5 onto the stator mounting rod 10, the stator mounting rod 10 is inserted into the limiting groove 12 and fixed in place. Then, the external power supply activates the hydraulic rod 8, causing it to pull the positioning frame 6 to slowly move downwards. During the downward movement of the positioning frame 6, the stator mounting rod 10 is moved downwards, which in turn moves the stator body 5 downwards. The downward movement stops when the stator body 5 is below the surface of the paint in the immersion box 1.

[0040] When impregnating the stator body 5 with paint, multiple sets of stator bodies 5 can be placed into the impregnation box 1 for simultaneous impregnation. Simultaneously, the drive motor 2 is started, causing the threaded rod 3 to rotate, which in turn drives the support base 7 to move laterally. The support base 7, through the positioning frame 6, causes the stator body 5 on the stator mounting rod 10 to move laterally within the impregnation box 1, thereby changing the position of the stator body 5. This allows for faster contact with the paint, improving the efficiency of the impregnation process. Furthermore, the stator body 5 can be moved back and forth, ensuring the paint more thoroughly impregnates its outer wall, preventing dead zones.

[0041] As the positioning frame 6 moves laterally, the scraper 11 also moves laterally, scraping the inner wall of the paint dipping box 1 to prevent paint from adhering to it. The reciprocating scraping action of the scraper 11 ensures thorough cleaning of the inner wall of the paint dipping box 1, leaving no blind spots and improving the cleaning effect.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
