Description

Technical Field

[0001] This utility model belongs to the technical field of motor assembly potting tooling, specifically relating to a motor assembly potting tooling. Background Technology

[0002] The motor assembly potting fixture is a specialized mold and fixture system used for precise potting of core components such as the stator and rotor of a motor. Its core function is to inject and fill insulating and thermally conductive adhesive into designated locations during motor assembly. Through structured cavity design, limiting components, and sealing modules, it ensures uniform distribution of the adhesive, no air bubbles, and no leakage, thereby achieving a one-time improvement in the motor's insulation, waterproofing, heat dissipation, and shock resistance performance. At the same time, it ensures accurate dimensions after potting and facilitates subsequent assembly. It is a key process equipment for improving the reliability and production efficiency of high-end motors.

[0003] When the motor assembly potting fixture is in use, the stator windings, as the main heat-generating component, will generate a lot of heat during motor operation. Since the potted stator is in close contact with the motor, this will reduce the heat dissipation effect. Utility Model Content

[0004] The purpose of this utility model is to provide a motor assembly potting fixture to solve the problem that when the motor assembly potting fixture mentioned in the background art is used, the stator winding, as the main heat-generating component, generates a lot of heat during motor operation. Since the potting stator is closely connected to the motor, this reduces the heat dissipation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor assembly potting fixture, comprising a motor assembly housing, an upper end cover installed at the front end of the motor assembly housing, a potting stator inserted into the interior of the motor assembly housing, the potting stator being fitted with a rubber block located inside the motor assembly housing, the rubber block being snapped into a square slot located on the inner wall of the motor assembly housing, a guide plate fixed on the inner wall of the motor assembly housing guiding the potting stator during insertion, and a metal base installed at the rear end of the motor assembly housing.

[0006] Preferably, the upper end cover has arc-shaped through grooves on the left and right sides of its front end, and multiple through holes are distributed at the front end of the upper end cover.

[0007] Preferably, a glue-limiting central column is inserted into the internal position of the glue-filled stator, and a lead wire fixing block is provided above the outer wall of the glue-limiting central column.

[0008] Preferably, a silicone base is installed at the rear end of the motor assembly housing, a groove is provided at one end of the silicone base, and the end face of the silicone base is in contact with the potted stator.

[0009] Preferably, the guide plate is fixed to the inner wall of the motor assembly housing in an annular structure, and the cross-sectional structure of the guide plate is triangular.

[0010] Preferably, a plurality of square slots are evenly distributed on the inner wall of the motor assembly housing, and a rubber block is installed on the inner wall of each square slot.

[0011] Preferably, a roller is fitted inside the rubber block, and the roller rotates around a pivot at one of its left or right ends, with the pivot located in a groove on the inner wall of the rubber block.

[0012] Preferably, the outer wall of the roller is in contact with the spring located inside the rubber block, and the roller can enter the inner position of the rubber block under the extrusion force, while the rotating shaft moves along the slide groove.

[0013] Compared with the prior art, this utility model provides a glue-pouring tooling for a motor assembly, which has the following beneficial effects: The housing of this device is thinner in certain areas compared to the original housing. Due to the thinner housing, there is a certain gap between the glued stator and the motor assembly housing during insertion. The glued stator is guided by a guide plate located on the inner wall of the motor assembly, allowing it to enter the appropriate internal position. The glued stator compresses the rubber block due to its flexibility, ensuring that the rubber block is tightly attached to the outer wall of the glued stator. This maintains a certain distance between the glued stator and the motor assembly housing. The close fit between the rubber block and the glued stator does not affect the stability of the glued stator installation, and the reserved gap increases heat dissipation.

[0014] A roller is fitted inside the rubber block. The roller rotates when it comes into contact with the glue-filling stator via a rotating shaft, guiding the glue-filling stator to move. At the same time, the movement of the glue-filling stator squeezes the roller. The rotating shaft of the roller moves synchronously along the slide groove, allowing the roller to enter the inner position of the rubber block. Finally, the rubber block and the glue-filling stator are bonded together. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The utility model provides, for example Figure 1-4The illustrated motor assembly potting fixture includes a motor assembly housing 2, an upper end cover 5 installed at the front end of the motor assembly housing 2, a potting stator 1 inserted into the interior of the motor assembly housing 2, the potting stator 1 being fitted with a rubber block 13 located inside the motor assembly housing 2, the rubber block 13 being snapped into a square slot 11 located on the inner wall of the motor assembly housing 2, a guide plate 12 fixed to the inner wall of the motor assembly housing 2 guiding the potting stator 1 during insertion, and a metal base 4 installed at the rear end of the motor assembly housing 2.

[0023] Place the stator 1 to be potted into the position inside the assembly housing, pass the three lead wires through the through hole 9 into the lead wire fixing block 6, and insert the fixing block into the root of the lead wires. Insert the glue limiting center post 7 into the inner diameter of the stator. The function of the glue limiting center post 7 is to ensure that the glue will not interfere with the subsequent assembly of the stator and rotor after potting. Install the upper end cover 5 and the metal base 4 on the motor assembly, ensuring that there is no gap.

[0024] The potting adhesive uses JSR20615A type epoxy resin. Epoxy resin is one of the thermosetting resins with the best electrical resistance. After curing, it has good electrical insulation properties and can be widely used for insulation protection of electronic and electrical equipment.

[0025] like Figure 2 and Figure 3 As shown, arc-shaped through grooves 8 are provided on the left and right sides of the front end of the upper end cover 5. Multiple through holes 9 are distributed at the front end of the upper end cover 5. A glue-limiting center post 7 is inserted into the interior of the glue-potting stator 1. A lead wire fixing block 6 is provided on the upper part of the outer wall of the glue-limiting center post 7. A silicone base 3 is installed inside the rear end of the motor assembly housing 2. A groove 10 is provided at one end of the silicone base 3. The end face of the silicone base 3 is attached to the glue-potting stator 1. The guide plate 12 is fixed in a ring structure to the inner wall of the motor assembly housing 2. The cross-sectional structure of the guide plate 12 is... The motor assembly housing 2 has a triangular structure. Multiple square slots 11 are evenly distributed on the inner wall of the housing. A rubber block 13 is installed on the inner wall of each square slot 11. A roller 15 is sleeved inside the rubber block 13. The roller 15 rotates around the pivot 16 at its left and right ends. The pivot 16 is located in the groove 17 on the inner wall of the rubber block 13. The outer wall of the roller 15 is in contact with the spring 14 located inside the rubber block 13. When the roller 15 is subjected to pressure, it can enter the inner position of the rubber block 13. At the same time, the pivot 16 moves along the groove 17.

[0026] Because the housing is thinner, there is a certain gap between the glued stator 1 and the motor assembly housing 2 during insertion. The guide plate 12 at the inner wall of the motor assembly guides the glued stator 1 into the inner position. Due to the flexibility of the rubber block 13, the glued stator 1 squeezes the rubber block 13, so that the rubber block 13 is tightly attached to the outer wall of the glued stator 1. This creates a certain distance between the glued stator 1 and the motor assembly housing 2. Because the rubber block 13 is attached to the glued stator 1, it does not affect the stability of the glued stator 1 during installation.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
