Description

Technical Field

[0001] This utility model belongs to the field of stator processing technology, specifically, it relates to a manual paint dripping fixture for stator production. Background Technology

[0002] Stator coating (drip coating, impregnation, and immersion curing) is a process of applying an insulating protective layer to the stator windings and slots of a motor. Its main purpose is to improve the electrical insulation strength between windings and between windings and the iron core, prevent partial discharge and insulation breakdown, and isolate moisture and corrosive media to enhance moisture and corrosion resistance. The cured coating layer can also fix the coils to reduce the relative movement caused by electromagnetic forces and mechanical vibrations, thereby reducing wear, short circuits and noise and extending service life.

[0003] Common processes include brushing, impregnation, flow impregnation, and vacuum pressure impregnation (VPI). Common paint systems include epoxy, polyester, polyurethane, and silicone resins. The appropriate system and curing process should be selected based on the motor's insulation class, operating temperature, and environmental conditions. The paint thickness and curing state must balance insulation and heat dissipation requirements; excessive thickness or poor curing may affect heat dissipation or lead to cracking and peeling. Quality control typically includes surface cleaning, degassing, withstand voltage testing, insulation resistance, paint peel strength, and aging tests to ensure long-term reliable operation.

[0004] Traditional paint dripping fixtures cannot be properly adapted to stators of different specifications, resulting in low work efficiency. Utility Model Content

[0005] To address the above deficiencies, this utility model provides a manual paint-drip fixture for stator production, comprising a cantilever for fixing and several adjusting mechanisms for fixing paint dripping tubes. A fixing plate is installed at the bottom of the cantilever, and the fixing plate is connected to the adjusting mechanisms via a rotating shaft at the bottom. The adjusting mechanism includes a rotating extension plate fixedly sleeved on the outer surface of the rotating shaft. Telescopic movable shafts are inserted into both sides of the rotating extension plate. A tube fixing block is connected to the rotating extension plate via the movable shafts, and a clamping assembly for clamping the paint dripping tube is installed at the tube fixing block.

[0006] Furthermore, the clamping assembly includes a clamping block and a hinge bolt, both of which are hinged to the end of the pipe fixing block away from the rotating extension plate by a pin. The clamping block has a U-shaped groove in the middle for inserting the hinge bolt, and the hinge bolt is limited to the U-shaped groove by a wing nut connected by a thread.

[0007] Furthermore, the paint dripping tube is clamped between the clamping block and the tube fixing block, and both clamping surfaces are provided with arc-shaped grooves that fit against the surface of the paint dripping tube.

[0008] Furthermore, the paint dripping tube includes at least one straight dripping tube and one curved dripping tube.

[0009] Compared with the prior art, the present invention has the following advantages: It can not only perform multi-directional paint dripping treatment on the stator to achieve the purpose of paint dripping, but also adapt to stators of different specifications and realize the function of real-time adjustment.

[0014] To facilitate understanding of this utility model, the device of this utility model will be described more fully below with reference to the accompanying drawings. Embodiments of the device are shown in the drawings. However, this device can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Example

[0017] like Figure 1-3 As shown, this embodiment provides a manual paint-drip fixture for stator production, including a cantilever 1 for fixing and several adjustment mechanisms 2 for fixing paint-drip tubes 3. A fixing plate 4 is installed at the bottom of the cantilever 1. The fixing plate 4 is connected to the adjustment mechanism 2 through a rotating shaft 5 at the bottom. The adjustment mechanism 2 includes a rotating extension plate 21 fixedly sleeved on the outer surface of the rotating shaft 5. Telescopic movable shafts 22 are inserted into both sides of the rotating extension plate 21. A tube fixing block 23 is connected to the rotating extension plate 21 through the movable shaft 22. A clamping component for clamping the paint-drip tube 3 is installed at the tube fixing block 23. The clamping assembly includes a clamping block 24 and a hinge bolt 25, both of which are hinged to the end of the pipe fixing block 23 away from the rotating extension plate 21 by a pin. The clamping block 24 has a U-shaped groove in the middle for the insertion of the hinge bolt 25. The hinge bolt 25 is limited to the U-shaped groove by the threaded butterfly nut 26. At the same time, the paint dripping tube 3 is clamped between the clamping block 24 and the pipe fixing block 23, and both clamping surfaces have arc-shaped grooves that fit with the surface of the paint dripping tube 3.

[0018] It should be noted that the number of rotating extension plates 21 and dripping tubes 3 is set according to actual needs. In order to adapt to stators of different specifications, multiple sets can be set, and the same number of clamping components can be set at the same time. When not in use, the moving shaft 22 can be pulled out so that the clamping components are away from the cantilever 1 (i.e. away from the stator) without affecting the dripping work. The dripping tube 3 should include at least one dripping straight tube and a dripping bend.

[0019] During operation, the cantilever 1 is fixedly installed at a suitable work position according to the tooling. The clamping assembly fixes the paint dripping bend and the paint dripping straight pipe to the end of the moving shaft 22. During paint dripping, the paint dripping bend drips paint onto the inside of the stator, and the paint dripping straight pipe drips paint onto the outside of the stator. At the same time, the distance between the paint dripping straight pipe or the paint dripping bend and the cantilever 1 can be adjusted according to the actual specifications of the stator (by adjusting the position of the moving shaft 22 on the rotating extension plate 21) to complete the paint dripping purpose. The rotating extension plate 21 can rotate around the bottom of the cantilever 1 to adjust the position of the paint dripping straight pipe or the paint dripping bend, so as to better drip paint onto the inside or outside of the stator.

[0020] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
