Description

Technical Field

[0001] This utility model belongs to the technical field of motor stator processing equipment, specifically a motor stator core impregnation device. Background Technology

[0002] The motor stator is one of the key components of the motor. After the winding coil is embedded in the iron core slot, the winding needs to be impregnated with varnish to fill the gaps between the iron core slot and the conductor and then cured to improve the insulation, moisture resistance and mechanical strength of the winding.

[0003] When impregnating stator cores with existing technology, the stator cores need to be placed on an impregnation basket before the impregnation operation is carried out. The impregnation basket is generally a fixed structure and can only hold stator cores of a fixed size. Different sizes of impregnation baskets are required when placing stator cores of different sizes, which is inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a device for impregnating motor stator cores with varnish, which can fix stator cores of different sizes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A motor stator core impregnation device is provided, comprising a base, an impregnation tank fixedly connected to the top of the base, a placement plate fixedly connected inside the impregnation tank, an impregnation basket fixedly connected to the top of the placement plate, a lifting mechanism fixedly connected to the middle of the top of the base, a scraper fixedly connected to the top of the lifting mechanism, the impregnation basket including a fixing block fixedly connected to the top of the placement plate, a screw movably connected inside the fixing block, a slider threadedly connected to the outside of the screw, a fixing post fixedly connected to the top of the slider, a placement block fixedly connected to the top of the fixing post, and a clamping plate fixedly connected to the top of the placement block.

[0006] Optionally, the base includes a seat body, the seat body having a fixing hole inside, a support column fixedly connected to the top of the seat body, and a reinforcing column fixedly connected between the support column and both the seat body and the impregnation tank.

[0007] Optionally, the lifting mechanism includes a motor fixedly connected to the middle of the top of the seat, a fixed cylinder fixedly connected to the top of the motor, a stud fixedly connected to the output end of the motor, a telescopic column threadedly connected to the outside of the stud, a lifting plate fixedly connected to the top of the telescopic column, and a sealing sleeve fixedly connected to the outside of the lifting plate.

[0008] Optionally, the impregnation tank includes a tank body fixedly connected to the top of the support column, and a discharge pipe fixedly connected to the outside of the tank body.

[0009] Optionally, the scraper sleeve includes a connecting column fixedly connected to the top of the lifting plate, a sleeve body fixedly connected to the top of the connecting column, and a rubber sleeve fixedly connected to the outer side of the sleeve body.

[0010] Optionally, the placement plate includes connecting blocks fixedly connected inside the barrel, and the plate body is fixedly connected between the connecting blocks, with through holes provided inside the plate body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model is equipped with a paint-impregnation basket. By turning the screw, the screw can rotate inside the fixed block. The forward and reverse rotation of the screw causes the slider to move back and forth inside the fixed block, which in turn drives the fixed column to move the placement block back and forth. This allows stator cores of different sizes to be placed on top of the placement block. After placement, the screw is turned again to move the placement block towards the center of the fixed block. Through continuous movement, the clamping plate can contact the stator core and fix it. The fixing is convenient and can fix stator cores of different sizes. Attached Figure Description

[0025] Reference Figures 1 to 6The present invention will now be described. A motor stator core impregnation device includes a base 1, an impregnation tank 3 fixedly connected to the top of the base 1, a placement plate 5 fixedly connected inside the impregnation tank 3, an impregnation basket 6 fixedly connected to the top of the placement plate 5, a lifting mechanism 2 fixedly connected to the middle of the top of the base 1, a scraper sleeve 4 fixedly connected to the top of the lifting mechanism 2, and an impregnation basket 6 including a fixing block 601 fixedly connected to the top of the placement plate 5. A screw 602 is movably connected inside the fixing block 601, and a slider 603 is threadedly connected to the outer side of the screw 602. The slider 603 can move inside the fixing block 601. A fixing post 604 is fixedly connected to the top of the slider 603, a placement block 605 is fixedly connected to the top of the fixing post 604, and a clamping plate 606 is fixedly connected to the top of the placement block 605. By turning the screw 602... 2. The screw 602 can rotate inside the fixed block 601. The forward and reverse rotation of the screw 602 causes the slider 603 to move back and forth inside the fixed block 601, thereby driving the fixed post 604 to move the placement block 605 back and forth. By adjusting the position of the placement block 605, the stator core can be placed on top of the placement block 605. After placement, the screw 602 is turned again to move the placement block 605 towards the center of the fixed block 601. Through continuous movement, the clamp 606 can contact the stator core to fix it. Fixing is convenient and can fix stator cores of different sizes. After fixing, the stator core is in a suspended state, which makes it easier to ensure that the insulating varnish can completely cover the stator core.

[0026] In another embodiment of this utility model, the base 1 includes a seat body 101. The seat body 101 has a fixing hole 102 inside. The base 1 can be fixed to the ground by using bolts through the fixing hole 102 to ensure that the base 1 can stably support the paint dipping tank 3. A support column 103 is fixedly connected to the top of the seat body 101. A reinforcing column 104 is fixedly connected between the support column 103, the seat body 101, and the paint dipping tank 3. The reinforcing column 104 is used to strengthen the strength of the base 1.

[0027] In another embodiment of this utility model, the lifting mechanism 2 includes a motor 201 fixedly connected to the middle of the top of the base 101. A fixed cylinder 203 is fixedly connected to the top of the motor 201. A stud 202 is fixedly connected to the output end of the motor 201. A telescopic column 204 is threadedly connected to the outer side of the stud 202. The telescopic column 204 can move up and down inside the fixed cylinder 203. A lifting plate 206 is fixedly connected to the top of the telescopic column 204. A sealing sleeve 205 is fixedly connected to the outer side of the lifting plate 206. The sealing sleeve 205 is made of rubber and is used to ensure better sealing between the lifting plate 206 and the barrel 301. By starting the motor 201... 1. The stud 202 is rotated, and the forward and reverse rotation of the stud 202 causes the telescopic column 204 to rise and fall inside the fixed cylinder 203, thereby driving the lifting plate 206 to rise and fall. When the lifting plate 206 moves upward, the insulating varnish also rises. Through continuous rising, the liquid level of the insulating varnish can be submerged over the stator core, allowing the insulating varnish to adhere to the outside of the stator core and the winding coil, and filling the gap between the stator core and the winding coil. After the varnish is impregnated, the lifting plate 206 is lowered, and the insulating varnish also falls, thereby exposing the stator core, making it easy to remove the stator core.

[0028] In another embodiment of the present invention, the impregnation tank 3 includes a tank body 301 fixedly connected to the top of the support column 103. The tank body 301 is used for storing insulating varnish. A discharge pipe 302 is fixedly connected to the outside of the tank body 301. By opening the discharge pipe 302 and by raising the lifting plate 206, the liquid level of the insulating varnish is kept higher than the discharge pipe 302, so that the insulating varnish inside the impregnation tank 3 can be discharged.

[0029] In another embodiment of this utility model, the scraper sleeve 4 includes a connecting column 401 fixedly connected to the top of the lifting plate 206. A sleeve body 402 is fixedly connected to the top of the connecting column 401, and a rubber sleeve 403 is fixedly connected to the outer side of the sleeve body 402. The connecting column 401 can drive the sleeve body 402 to rise and fall by the lifting plate 206, thereby enabling the rubber sleeve 403 to rise and fall. When the lifting plate 206 descends after the varnish impregnation is completed, the rubber sleeve 403 also descends accordingly. By continuously descending, the rubber sleeve 403 can scrape off the insulating varnish adhering to the inner wall of the barrel 301, ensuring that the inner wall of the barrel 301 is cleaner and facilitating the saving of insulating varnish. It also prevents the insulating varnish on the inner wall of the barrel 301 from drying out and becoming unusable. Furthermore, the lower part of the rubber sleeve 403 is set at an angle, allowing the insulating varnish on the rubber sleeve 403 to flow downward more easily under the action of gravity, further saving insulating varnish.

[0030] In another embodiment of this utility model, the placement plate 5 includes a connecting block 503 fixedly connected inside the barrel 301, and a plate 501 fixedly connected between the connecting blocks 503. The plate 501 has a through hole 502 inside. The plate 501 is used to fix the varnish-impregnating basket 6, and the through hole 502 is used for the passage of insulating varnish, so that the insulating varnish can submerge the top of the stator core under the action of the lifting plate 206.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
