Description

Technical Field

[0001] This utility model relates to the field of impregnation fixture technology, and in particular to a vacuum impregnation fixture for a disc motor stator. Background Technology

[0002] In the vacuum impregnation process of disc motor stators, the stator needs to be fixed by clamps and immersed in insulating varnish to ensure that the varnish fully penetrates the stator windings, improving insulation performance and durability. Existing technology (such as CN214682405U) proposes a stator impregnation bracket that suspends the stator using a hanger, avoiding direct contact between the bracket and the insulating varnish, thus reducing varnish residue. The bracket can be reused after cleaning only the hanger. However, this technical solution has the following shortcomings:

[0003] Low assembly and disassembly efficiency: The stator is suspended by a lifting device, but no quick assembly and disassembly structure is provided. The connection between the lifting device and the stator needs to be manually adjusted, which is cumbersome and time-consuming, especially affecting efficiency in mass production.

[0004] Poor positioning stability: The connection between the lifting device and the stator is not clearly defined and fixed, which can easily cause the stator to shift due to vibration or paint impact during the paint impregnation process, affecting the uniformity of paint impregnation.

[0005] Insufficient versatility: The fixed size of the lifting device makes it difficult to adapt to different stator specifications, requiring the replacement of the lifting device to accommodate different sizes, which increases equipment costs and maintenance difficulty. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum impregnation fixture for disc motor stators. Through an elastic locking mechanism and a modular positioning structure, it solves the problems of low stator assembly and disassembly efficiency, poor positioning stability, and insufficient versatility in the prior art. It significantly improves the efficiency, quality, and equipment versatility of the vacuum impregnation process for disc motor stators, and is especially suitable for automated production lines with multiple varieties and large quantities.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] A vacuum impregnation fixture for a disc motor stator includes:

[0009] The paint-impregnation hanger has a lifting lug on its top for suspending the hanger, and a number of hanging rods arranged at equal intervals are installed on the hanger. The bottom of each hanging rod is equipped with a detachable positioning component.

[0010] In the aforementioned disc motor stator vacuum impregnation fixture, the positioning component includes a positioning seat, a hollow connecting block is fixedly connected to the top of the positioning seat, and a connecting groove is provided at the bottom of the hanging rod to cooperate with the hollow connecting block.

[0011] In the aforementioned disc motor stator vacuum impregnation fixture, both sides of the hollow connecting block are slidably connected with sliding pins, and both sides of the inner wall of the connecting groove are provided with positioning slots that match the sliding pins.

[0012] In the aforementioned disc motor stator vacuum impregnation fixture, a center plate is fixedly connected to the inner wall of the hollow connecting block, and abutment springs are fixedly connected to both sides of the center plate. An operating linkage is fixedly connected to the other end of the abutment spring, and the side of the operating linkage near the sliding pin is fixedly connected to the side of the sliding pin.

[0013] In the above-mentioned vacuum impregnation fixture for disc motor stators, a positioning groove matching the operating link is provided on the positioning seat at the position corresponding to the operating link, and the operating link is slidably connected to the inner wall of the positioning groove.

[0014] In the aforementioned disc motor stator vacuum impregnation fixture, a pressing pad is also fixedly connected to the side of the operating linkage.

[0015] The aforementioned disc motor stator vacuum impregnation fixture includes a removable sealing sleeve at the bottom of the positioning seat.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. This utility model realizes a vacuum impregnation fixture for disc motor stators. Through the elastic locking mechanism and modular positioning structure, it solves the problems of low stator assembly and disassembly efficiency, poor positioning stability and insufficient versatility in the prior art. It significantly improves the efficiency, quality and equipment versatility of the vacuum impregnation process for disc motor stators, and is especially suitable for automated production lines with multiple varieties and large quantities.

[0018] 2. By squeezing the operating lever to compress the abutment spring, the sliding pin retracts into the hollow connecting block, enabling quick insertion of the positioning seat and the hanging rod. After releasing the operating lever, the sliding pin automatically engages with the positioning slot under the elastic force of the abutment spring, completing the locking process. Disassembly can be performed by reversing the operation, reducing the single disassembly and assembly time to a few seconds, significantly improving production cycle time.

[0019] 3. The positioning seat is rigidly connected to the positioning slot through a sliding pin to ensure that the stator does not shake or shift during the paint impregnation process; at the same time, the mating structure between the hanging rod and the positioning seat can withstand the impact force of the paint impregnation, preventing the stator from falling off or the paint from being unevenly distributed.

[0020] 4. The connection between the hanging rod and the positioning seat is not dependent on the stator size. Only the diameter of the hanging rod or the position of the positioning slot needs to be adjusted to adapt to stators with different outer diameters. There is no need to replace the entire fixture, reducing equipment investment and spare parts inventory.

[0021] 5. The positioning seat can be disassembled independently. After dipping in paint, only the paint on the surface of the positioning seat needs to be cleaned. There is no need to treat the hanging rod or frame, which reduces the difficulty of maintenance. At the same time, there is no paint residue on the hanging rod, which avoids structural jamming caused by paint layer accumulation after long-term use. Attached Figure Description

[0034] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0035] Please refer to Figures 1 to 4As shown, an embodiment of the present invention provides a vacuum impregnation fixture for a disc motor stator, comprising: an impregnation hanger 1, a lifting lug for suspending the impregnation hanger 1 on the top of the impregnation hanger 1, a plurality of hanging rods 2 arranged at equal intervals on the impregnation hanger 1, and a detachable positioning component 3 installed at the bottom of the hanging rods 2.

[0036] By adopting the above technical solution, the elastic locking mechanism of the positioning seat 3012, in conjunction with the sliding pin 302 and the positioning slot 3021, enables quick one-handed insertion and disassembly, significantly improving the efficiency of stator assembly and disassembly. Its rigid support structure and anti-detachment design ensure the stability of the stator during the impregnation process, guaranteeing uniform paint penetration. The modular design allows the positioning seat 3012 to be independently adapted to stators of multiple sizes, reducing equipment costs and maintenance difficulty. At the same time, only the paint on the surface of the positioning seat 3012 needs to be cleaned, avoiding residue on the hanging rod 2, further simplifying the maintenance process and comprehensively improving the efficiency, quality, and versatility of the vacuum impregnation process for disc motor stators.

[0037] To achieve quick insertion and adaptation between the positioning seat 3012 and the hanging rod 2, in this embodiment: the positioning component 3 includes a positioning seat 3012, a hollow connecting block 301 is fixedly connected to the top of the positioning seat 3012, and a connecting groove 3011 is provided at the bottom of the hanging rod 2 to cooperate with the hollow connecting block 301. The insertion structure of the hollow connecting block 301 and the connecting groove 3011 enables quick docking between the positioning seat 3012 and the hanging rod 2 without the need for complex tools or adjustments, has strong adaptability, and significantly improves assembly efficiency.

[0038] To achieve a stable locking and anti-detachment function for the positioning seat 3012, in this embodiment: sliding pins 302 are slidably connected to both sides of the hollow connecting block 301; positioning slots 3021 matching the sliding pins 302 are provided on both sides of the inner wall of the connecting groove 3011 at positions corresponding to the sliding pins 302; a center plate 303 is fixedly connected to the inner wall of the hollow connecting block 301; abutment springs 3031 are fixedly connected to both sides of the center plate 303; an operating rod 3032 is fixedly connected to the other end of the abutment springs 3031; and the side of the operating rod 3032 closest to the sliding pins 302 is fixedly connected to the side of the sliding pins 302. The engagement structure between the sliding pins 302 and the positioning slots 3021 ensures that the positioning seat 3012 has no risk of shaking or falling off during the paint impregnation process; the abutment springs 3031 provide elastic locking force, and the operating rods 3032 enable one-handed unlocking, balancing stability and ease of operation.

[0039] To ensure the linear motion stability of the operating link 3032, in this embodiment: a positioning groove 304 matching the operating link 3032 is provided on the positioning seat 3012 at the position corresponding to the operating link 3032, and the operating link 3032 is slidably connected to the inner wall of the positioning groove 304. The positioning groove 304 restricts the movement trajectory of the operating link 3032, avoids deviation or jamming, ensures that the sliding pin 302 accurately enters and exits the positioning slot 3021, and improves the structural reliability.

[0040] To improve operational comfort and anti-slip properties, in this embodiment, a pressing pad 305 is also fixedly connected to the side of the operating linkage 3032. The pressing pad 305 is made of a flexible material such as rubber, which increases the contact area between the operating linkage 3032 and the fingers, reduces the pressure on the fingers during operation, and at the same time, the anti-slip design prevents accidental operation due to slippage.

[0041] To prevent paint from seeping into the positioning seat 3012 and to protect the internal structure, in this embodiment, a removable sealing sleeve 306 is also provided at the bottom of the positioning seat 3012. The sealing sleeve 306 seals the bottom of the positioning seat 3012, preventing paint from seeping into the hollow connecting block 301 during the paint immersion process, protecting the abutment spring 3031 and the operating linkage 3032 from corrosion, and extending their service life; the removable design makes it easy to clean residual paint.

[0042] The working principle of this utility model is as follows:

[0043] Quick Installation: After placing the stator to be impregnated onto the hanging rod 2, pinch the operating linkage 3032 at the bottom of the positioning seat 3012. Press the pad 305 to enhance operating comfort. The operating linkage 3032 slides along the positioning groove 304, compressing the abutment spring 3031 and causing the sliding pin 302 to retract into the hollow connecting block 301. At this time, insert the hollow connecting block 301 into the connecting groove 3011 at the bottom of the hanging rod 2. When the sliding pin 302 aligns with the positioning groove 3021, release the operating linkage 3032. The abutment spring 3031 resets and pushes the sliding pin 302 into the positioning groove 3021, completing the quick locking of the positioning seat 3012 and supporting the stator for stable impregnation.

[0044] Easy disassembly: After the paint is applied, squeeze the operating lever 3032 again to disengage the sliding pin 302 from the positioning slot 3021, and then pull the positioning seat 3012 off the hanging rod 2 to easily remove the stator.

[0045] Paint protection: The sealing sleeve 306 at the bottom of the positioning seat 3012 seals the internal structure to prevent paint from seeping in; after disassembly, only the paint on the surface of the sealing sleeve 306 needs to be cleaned, making maintenance simple.
