Description

Technical Field

[0001] The utility model relates to the field of varnish dipping, in particular to a vacuum varnish dipping structure for producing synchronous reluctance motors. Background Art

[0002] The synchronous reluctance motor is a new type of AC motor that follows the principle of closed path with minimum magnetic resistance and generates magnetic pull to drive the motor to rotate through the change of magnetic resistance caused by the rotor at different positions. It has the advantages of simple structure, durability, and wide speed regulation range. It is mainly used in industrial and agricultural production, transportation, commerce, and household appliances.

[0003] After synchronous reluctance motors are produced, they are often vacuum-dipped for varnishing. The significance of this is that there are a large number of gaps in the motor windings, which can easily absorb moisture in the air and reduce the insulation performance. Through varnishing, the moisture resistance and mechanical strength of the winding insulation can be improved, while the thermal conductivity can also be increased and the heat dissipation conditions can be improved.

[0004] When a synchronous reluctance motor is dipped in paint, it is necessary to put the synchronous reluctance motor into a dip paint tank filled with paint and soak it for a long time so that the motor is completely covered with the paint. Since there are areas in the motor windings that are difficult to completely penetrate, the motor in the dip paint tank needs to be rotated to assist the paint to penetrate better. However, when the motor is rotated, the motor may be separated from the connection structure due to loose contact, which may cause damage to the motor and lead to production interruption. Therefore, in view of the above problem, a vacuum dip paint structure for synchronous reluctance motor production is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a vacuum varnishing structure for synchronous reluctance motor production comprises a varnishing tank 1; a first fastening ring 11 is fixedly connected to the middle of the varnishing tank 1; a plurality of electric push rods 12 are fixedly connected to the middle of the first fastening ring 11; a cover plate 13 is fixedly connected to the end of the electric push rod 12; an inner tank 14 is fixedly connected to the middle of the varnishing tank 1; a motor 15 is fixedly connected to the top of the cover plate 13; a rotating shaft 16 is rotatably connected to the middle of the cover plate 13; a plurality of supporting plates 17 are fixedly connected to the middle of the rotating shaft 16; a plurality of connecting columns 18 are fixedly connected to the middle of the supporting plate 17; a plurality of connecting columns 18 are fixedly connected to the ends of the connecting columns 18 The storage box 19 is provided with a plurality of filter holes 111 on all four sides; the storage box 19 is fixedly connected with a slide column 112 on both sides; the middle of the slide column 112 is slidably connected with a plurality of clamping plates 113; the two sides of the connecting column 18 are fixedly connected with a threaded sleeve 114; the middle of the threaded sleeve 114 is rotatably connected with a threaded rod 115; when working, when it is necessary to vacuum dip paint the synchronous reluctance motor, the electric push rod 12 is first used to lift the cover plate 13, thereby driving the rotating shaft 16 to leave the interior of the dip paint tank 1, and then the motor is placed in the storage box 19, and then the threaded sleeve 114 is screwed. The rod 115 makes the threaded rod 115 rotate inside the threaded sleeve 114, and the rotation of the threaded rod 115 pushes the card plate 113 to move closer to the middle of the storage box 19 until the card plate 113 clamps the motor inside the storage box 19, and then the cover plate 13 is driven down by the electric push rod 12 until the bottom of the cover plate 13 is closed with the top of the immersion tank 1. When it is necessary to rotate the synchronous reluctance motor inside the storage box 19 for better immersion, the motor 15 can be operated to drive the rotating shaft 16 to rotate. In this step, the motor 15 drives the rotating shaft 16 to rotate. Rotation can make the synchronous reluctance motor inside the paint dipping tank 1 better contact with the paint, and prevent the existence of difficult-to-penetrate areas in the motor windings, thereby affecting the efficiency of the motor's paint dipping and causing the paint dipping degree to be unqualified. Under the mutual cooperation of the threaded rod 115 and the clamping plate 113, the synchronous reluctance motor inside the storage box 19 can be fixed to prevent the synchronous reluctance motor from being affected and detached from the storage box 19 when the rotating shaft 16 rotates, causing it to be damaged and having a negative impact on the production plan and production efficiency.

[0025] like Figure 2 , Figure 3As shown, a plurality of stirring blades 2 are fixedly connected to the middle of the rotating shaft 16; a first horizontal plate 21 is fixedly connected to the top of the rotating shaft 16; vertical plates 22 are fixedly connected to both ends of the first horizontal plate 21; a second horizontal plate 23 is fixedly connected to the bottom of the rotating shaft 16; a first rubber plate 24 is fixedly connected to the sides of the vertical plates 22; a second rubber plate 25 is fixedly connected to the bottom of the second horizontal plate 23; during operation, when the rotating shaft 16 rotates, the stirring blades 2, the first horizontal plate 21 and the second horizontal plate 23 will rotate with the rotation of the rotating shaft 16, and when the first horizontal plate 21 rotates, it will drive the vertical plates 22 to clean the inner wall of the inner pot 14, and when the second horizontal plate 23 rotates, it will clean the bottom of the inner pot 14. This step is performed by The stirring blade 2 can stir the paint inside the inner tank 14 to make the paint flow, so as to prevent the paint from becoming viscous or even caking due to the long time of not flowing during the paint dipping, which will cause the paint surface of the synchronous reluctance motor to be uneven after paint dipping and affect its performance. The vertical plate 22 and the second horizontal plate 23 can prevent the paint from adhering to the inner wall of the inner tank 14, which will affect the stirring blade 2 to stir all the paint inside the threaded sleeve 114. The first rubber plate 24 and the second rubber plate 25 can protect the inner wall of the inner tank 14 and reduce the friction between the vertical plate 22, the second horizontal plate 23 and the inner wall of the inner tank 14.

[0026] like Figure 2 , Figure 5 As shown, a plurality of heating pumps 3 are fixedly connected to the bottom of the paint dipping tank 1; a heat conducting plate 31 is fixedly connected to the ends of the heating pumps 3; a plurality of heat sinks 32 are fixedly connected to the middle of the heat conducting plate 31; the ends of the heat sinks 32 are fixedly connected to the bottom of the inner tank 14; when working, the heating pump 3 can generate heat, the heat conducting plate 31 can conduct the heat emitted by the heating pump 3 to the heat sink 32, and the heat sink 32 then transfers the heat through the bottom of the inner tank 14 to the paint inside the inner tank 14. This step can heat the paint inside the inner tank 14 through the heating pump 3, thereby improving the fluidity of the paint, and at the same time, it can also make the paint more evenly coated on the surface of the synchronous reluctance motor, reduce the floating and precipitation phenomena of the paint, and improve the coating effect.

[0027] like Figure 2As shown, the inner wall of the paint dipping tank 1 is fixedly connected to multiple groups of first shock-absorbing pads 4; the middle part of the first shock-absorbing pads 4 is fixedly connected to multiple groups of buffer springs 41; the ends of the buffer springs 41 are fixedly connected to second shock-absorbing pads 42; one side of the second shock-absorbing pad 42 is fixedly connected to the side of the inner tank 14; during operation, the motor 15 generates a certain vibration when working, and at this time the vibration force will be transmitted to the second shock-absorbing pad 42 through the inner tank 14, and the second shock-absorbing pad 42 can initially relieve the vibration force, and then transmit the remaining vibration force to the buffer spring 41, and the buffer spring 41 is affected by the vibration force and stretched, so that the vibration force can be relieved again, and the vibration force is transmitted to the first shock-absorbing pad 4, and finally the vibration force is finally weakened by the first shock-absorbing pad 4, and this step can achieve the effect of damping and noise reduction on the noise generated by the operation of the motor 15 through the damping of the first shock-absorbing pad 4, the buffer spring 41 and the second shock-absorbing pad 42, thereby reducing the transmission of noise and noise pollution, and creating a better working environment for the workers.

[0028] like Figure 1 , Figure 2 As shown, a second fastening ring 5 is fixedly connected to the middle of the motor 15; a plurality of groups of pillars 51 are fixedly connected to the middle of the second fastening ring 5; the bottom of the pillars 51 are fixedly connected to the top of the cover plate 13; when working, the second fastening ring 5 plays a role in stabilizing the motor 15, and the pillars 51 can assist the second fastening ring 5 in fixing the motor 15. In this step, the vibration generated by the operation of the motor 15 can be reduced through the cooperation between the second fastening ring 5 and the pillars 51, so as to prevent the motor 15 from shaking due to vibration, thereby affecting the rotation of the shaft 16, resulting in the shaft 16 not being able to stir the paint inside the inner tank 14 well.

[0029] like Figure 2 As shown, a sealing ring 6 is fixedly connected to the middle of the cover plate 13; when working, the sealing ring 6 can increase the sealing effect between the cover plate 13 and the paint dipping tank 1. This step can prevent the paint inside the inner tank 14 from splashing out through the interface between the cover plate 13 and the paint dipping tank 1 during the stirring process through the effect of the sealing ring 6.

[0030] like Figure 1 As shown, a glass observation plate 7 is fixedly connected to the middle of the paint dipping tank 1; when working, the glass observation plate 7 is opened to observe the situation inside the paint dipping tank 1. In this step, the glass observation plate 7 can be used to observe the stirring of the paint, and it can be determined when to stop stirring the paint.

[0031] Working principle: during operation, when the synchronous reluctance motor needs to be vacuum dipped in paint, the electric push rod 12 is first used to lift the cover plate 13, thereby driving the rotating shaft 16 to leave the paint dipping tank 1, and then the motor is placed in the storage box 19, and then the threaded rod 115 is screwed to rotate the threaded rod 115 inside the threaded sleeve 114. The rotation of the threaded rod 115 will push the clamping plate 113 to the middle of the storage box 19 until the clamping plate 113 clamps the motor inside the storage box 19, and then the cover plate 13 is driven down by the electric push rod 12 until the bottom of the cover plate 13 is closed with the top of the paint dipping tank 1. When the synchronous reluctance motor inside the storage box 19 needs to be rotated for better dipping, the motor 15 can be operated to drive the rotating shaft 16 to rotate. That is, in this step, the motor 15 drives the rotating shaft 16 to rotate, so that the synchronous reluctance motor inside the paint dipping tank 1 can better contact with the paint, and prevent the existence of difficult-to-penetrate areas in the motor windings, thereby affecting the efficiency of the motor's paint dipping and causing the paint dipping degree to be unqualified. Under the mutual cooperation of the threaded rod 115 and the clamping plate 113, the synchronous reluctance motor inside the storage box 19 can be fixed to prevent the synchronous reluctance motor from being affected and detached from the storage box 19 when the rotating shaft 16 rotates, causing it to be damaged and having a negative impact on the production plan and production efficiency. During operation, when the rotating shaft 16 rotates, the stirring blade 2, the first horizontal plate 21 and the second horizontal plate 23 will rotate with the rotation of the rotating shaft 16. When the first horizontal plate 21 rotates, the vertical plate 22 is driven to clean the inner wall of the inner tank 14, and when the second horizontal plate 23 rotates, the bottom of the inner tank 14 is cleaned. In this step, the paint inside the inner tank 14 can be stirred by the stirring blade 2 to make the paint flow, so as to prevent the paint from becoming viscous or even agglomerating due to the long time of not flowing during the paint dipping, thereby causing the paint surface of the synchronous reluctance motor to be uneven after the paint dipping and affecting its performance. The vertical plate 22 and the second horizontal plate 23 can prevent the paint from adhering to the inner wall of the inner tank 14, which affects the stirring blade 2 to stir all the paint inside the threaded sleeve 114. The first rubber plate 24 and the second rubber plate 25 can protect the inner tank 14. The function of the wall is to reduce the friction between the vertical plate 22, the second horizontal plate 23 and the inner wall of the inner tank 14. When working, the heating pump 3 can generate heat, and the heat conducting plate 31 can conduct the heat emitted by the heating pump 3 to the heat sink 32. The heat sink 32 then transfers the heat to the paint inside the inner tank 14 through the bottom of the inner tank 14. This step can heat the paint inside the inner tank 14 through the heating pump 3, thereby improving the fluidity of the paint, and also making the paint more evenly coated on the surface of the synchronous reluctance motor, reducing the floating bottom and precipitation of the paint, and improving the coating effect. When working, the motor 15 generates a certain vibration when working. At this time, the vibration force will be transmitted to the second shock absorbing pad 42 through the inner tank 14, and the second shock absorbing pad 42 can initially alleviate the vibration force.Then the remaining vibration force is transmitted to the buffer spring 41, and the buffer spring 41 is stretched by the vibration force, so that the vibration force can be relieved again, and the vibration force is transmitted to the first shock-absorbing pad 4, and finally the vibration force is finally weakened by the first shock-absorbing pad 4. In this step, the shock absorption of the first shock-absorbing pad 4, the buffer spring 41 and the second shock-absorbing pad 42 can achieve the effect of shock absorption and noise reduction on the noise generated by the operation of the motor 15, reduce the transmission of noise and noise pollution, and create a better working environment for the workers. When working, the second fastening ring 5 stabilizes the motor 15, and the pillar 51 can assist the second fastening ring 5 to fix the motor 15. In this step, the second fastening ring 5 and the pillar 51 are mutually supported. With the cooperation, the vibration generated by the motor 15 can be reduced, so as to prevent the motor 15 from shaking due to vibration, thereby affecting the rotation of the shaft 16, resulting in the shaft 16 not being able to stir the paint inside the inner tank 14 well. When working, the sealing ring 6 can increase the sealing effect between the cover plate 13 and the paint immersion tank 1. This step can prevent the paint inside the inner tank 14 from splashing through the interface between the cover plate 13 and the paint immersion tank 1 during the stirring process through the effect of the sealing ring 6. When working, the opening of the glass observation plate 7 can observe the situation inside the paint immersion tank 1. This step can facilitate the observation of the stirring situation of the paint through the effect of the glass observation plate 7, and it can be judged when to stop stirring the paint by observation.
