Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor stator press technology, specifically a new energy vehicle motor stator press. Background Technology
[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. The electric motor is one of the structural components that distinguishes new energy vehicles from gasoline vehicles. It is the core component that provides forward propulsion for new energy vehicles, determining their load capacity, acceleration, climbing ability, and maximum speed, and also influencing their overall energy consumption and driving range to a certain extent. The production and processing of new energy vehicle electric motors requires the use of presses to process the stator.
[0003] Common stator presses for new energy vehicle motors typically consist of a worktable, hydraulic equipment, and a pressure plate. During operation, the stator assembly is placed at the top center of the worktable. The hydraulic equipment then lowers the connected pressure plate, bringing it into contact with the top of the stator assembly, thus pressing the stator into place. This is the common structure and usage of new energy vehicle motor stator presses. Traditional new energy vehicle motor stator presses often use exposed motor housings placed in dusty workshops. This dust buildup, if not removed, significantly increases friction between the stator's outer wall and the motor housing's inner wall during subsequent stator tooling, severely impacting the tooling effect. Some new energy vehicle motor stator presses incorporate cleaning and blowing structures on the worktable to remove dust. However, this method allows dust to disperse and adhere to other motor housings, further expanding the dust's spread.
[0004] Therefore, we propose a stator press for new energy vehicle motors. Utility Model Content
[0005] The purpose of this invention is to provide a stator press for a new energy vehicle motor to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stator press for a new energy vehicle motor, comprising a frame, an operating platform fixedly installed in the middle of the frame, an exhaust fan installed at the bottom rear side of the frame, a filter box fixedly installed at the bottom rear side of the frame, an air inlet duct of the exhaust fan communicating with the air outlet of the filter box, a connecting duct fixedly installed at the air inlet of the filter box, a lower mold base installed in the middle of the operating platform, and cleaning push rods fixedly installed on both sides of the lower mold base at the top of the operating platform. A movable block is fixedly installed on the movable end of the push rod. An exterior wall brush is fixedly installed on the side of one of the movable blocks. Dust collection grooves are fixedly installed on the front and rear sides of the exterior wall brush. A lifting push rod is fixedly installed on the side of the other movable block. A connecting frame is fixedly installed on the movable end of the top of the lifting push rod. An inner wall brush is fixedly installed at the bottom of the connecting frame. Another dust collection groove is fixedly installed in the middle of the inner wall brush facing the lifting push rod. A connecting hose is fixedly installed on the top of the dust collection groove. The other end of the connecting hose is fixedly installed to a connecting conduit.
[0007] Optionally, a support column is fixedly installed in the middle of the operating table, and a top plate located inside the frame is fixedly installed on the top of the support column. A lifting plate located below the top plate is slidably connected through the support column. A hydraulic push rod is fixedly installed in the middle of the top of the top plate. The movable end of the bottom of the hydraulic push rod is fixedly installed with the middle of the lifting plate. An upper mold ring located directly above the lower mold base is fixedly installed at the bottom of the lifting plate.
[0008] Optionally, a rotating shaft is rotatably connected through the middle of the operating table, the lower mold base is fixedly installed on the top of the rotating shaft, and a gear is fixedly installed on the bottom of the rotating shaft.
[0009] Optionally, a rack located behind the rotating shaft is slidably connected to the bottom of the operating table, and a movable push rod located behind the rack is fixedly installed on the bottom of the operating table. The movable end of the movable push rod is fixedly installed with one end of the rack, and the rack meshes with a gear.
[0010] Optionally, the moving push rod, cleaning push rod, and lifting push rod are electric push rods with a self-locking function.
[0011] Optionally, both the exterior wall brush and the interior wall brush are long-bristled brushes, and the dust collection ports of the dust collection grooves on both sides of the exterior wall brush are arranged opposite each other.
[0012] Optionally, a slide rail is fixedly installed on the top of the operating table between the lower mold base and the cleaning push rod, and the bottom of the moving block is slidably connected to the slide rail.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This new energy vehicle motor stator press, equipped with external and internal wall brushes, places the motor housing on a lower mold base. The lower mold base then rotates the motor housing, causing the cleaning push rod to extend and move the external and internal wall brushes to the motor housing. Simultaneously, a lifting push rod raises the internal wall brush. Once the internal wall brush is above the inside of the motor housing, it descends, inserting the brush into the housing. As the motor housing rotates, the external and internal wall brushes clean it. Meanwhile, a blower creates negative pressure at the suction duct, drawing the dust removed by the brushes into a filter box via a suction duct and connecting pipe. This prevents the dust from scattering in the air and contaminating surrounding workpieces.
[0015] This new energy vehicle motor stator press, by setting a movable push rod, places the motor housing on the lower mold base. The movable push rod extends and retracts, causing the rack to move back and forth, which in turn causes the gear to drive the rotating shaft and the lower mold base to rotate, facilitating the cleaning of the exterior and interior walls by the brushes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4 This utility model provides a stator press for a new energy vehicle motor, including a frame 1. An operating platform 2 is fixedly installed in the middle of the frame 1. An exhaust fan 13 is installed at the bottom rear side of the frame 1, and a filter box 14 is fixedly installed at the bottom rear side of the frame 1. The air inlet duct of the exhaust fan 13 is connected to the air outlet of the filter box 14. A connecting duct 15 is fixedly installed at the air inlet of the filter box 14. A lower mold base 9 is provided in the middle of the operating platform 2, and two parts located on the top of the operating platform 2 are fixedly installed on the lower mold base 9. A cleaning push rod 16 is mounted on the side. A movable block 18 is fixedly installed on the movable end of the cleaning push rod 16. An exterior wall brush 19 is fixedly installed on the side of one movable block 18. A dust collection groove 20 is fixedly installed on the front and rear sides of the exterior wall brush 19. A lifting push rod 22 is fixedly installed on the side of the other movable block 18. A connecting frame 23 is fixedly installed on the movable end of the top of the lifting push rod 22. An inner wall brush 24 is fixedly installed at the bottom of the connecting frame 23. The middle part of the inner wall brush 24 facing the lifting push rod 22 is fixedly installed. There is another suction trough 20, and a connecting hose 21 is fixedly installed on the top of the suction trough 20. The other end of the connecting hose 21 is fixedly installed to the connecting conduit 15. By setting the outer facade brush 19 and the inner wall brush 24, after the motor housing is placed on the lower mold base 9, the lower mold base 9 drives the motor housing to rotate, the cleaning push rod 16 extends, and moves the outer facade brush 19 and the inner wall brush 24 to the motor housing. At the same time, the lifting push rod 22 drives the inner wall brush 24 to rise. When the inner wall brush 24 moves to the motor housing, the cleaning push rod 16 extends, moving the outer facade brush 19 and the inner wall brush 24 to the motor housing. The inner wall brush 24 is then lowered from the top inside the outer casing and sent into the motor casing. As the motor casing rotates, the outer wall brush 19 and the inner wall brush 24 clean the motor casing. At the same time, the exhaust fan 13 generates negative pressure at the suction slot, so that the dust brushed off by the outer wall brush 19 and the inner wall brush 24 is sucked into the filter box 14 through the dust suction slot 20 and the connecting pipe 15 for collection. This prevents the dust from being scattered in the air and causing pollution to the surrounding workpieces.
[0023] A support column 3 is fixedly installed in the middle of the operating table 2. A top plate 4 located inside the frame 1 is fixedly installed on the top of the support column 3. A lifting plate 6 located below the top plate 4 is slidably connected through the support column 3. A hydraulic push rod 5 is fixedly installed in the middle of the top of the top plate 4. The movable end of the bottom of the hydraulic push rod 5 is fixedly installed in the middle of the lifting plate 6. An upper mold ring 7 located directly above the lower mold base 9 is fixedly installed at the bottom of the lifting plate 6.
[0024] A rotating shaft 8 is rotatably connected through the middle of the operating table 2. The lower mold base 9 is fixedly installed on the top of the rotating shaft 8, and a gear 12 is fixedly installed on the bottom of the rotating shaft 8.
[0025] The bottom of the operating table 2 is slidably connected to a rack 11 located behind the rotating shaft 8. A movable push rod 10 located behind the rack 11 is fixedly installed at the bottom of the operating table 2. The movable end of the movable push rod 10 is fixedly installed with one end of the rack 11. The rack 11 meshes with the gear 12. By setting the movable push rod 10, after the motor housing is placed on the lower mold base 9, the movable push rod 10 extends and retracts, causing the rack 11 to move back and forth. This causes the gear 12 to drive the rotating shaft 8 and the lower mold base 9 to rotate, which facilitates the cleaning of the exterior wall brush 19 and the interior wall brush 24.
[0026] The movable push rod 10, the cleaning push rod 16, and the lifting push rod 22 are electric push rods with self-locking function.
[0027] Both the exterior wall brush 19 and the interior wall brush 24 use long-bristled brushes, and the dust collection ports of the dust collection grooves 20 on both sides of the exterior wall brush 19 are set opposite to each other.
[0028] The top of the operating table 2 is fixedly installed with a slide rail 17 located between the lower mold base 9 and the cleaning push rod 16, and the bottom of the moving block 18 is slidably connected to the slide rail 17.
[0029] Working principle:
[0030] After the motor housing is placed on the lower mold base 9, the push rod 10 is extended and retracted, causing the rack 11 to move back and forth. This causes the gear 12 to drive the rotating shaft 8 and the lower mold base 9 to rotate. The cleaning push rod 16 extends, moving the exterior wall brush 19 and the interior wall brush 24 to the motor housing. At the same time, the lifting push rod 22 drives the interior wall brush 24 to rise. When the interior wall brush 24 moves to the top of the motor housing, it descends, sending the interior wall brush 24 into the motor housing. As the motor housing rotates, the exterior wall brush 19 and the interior wall brush 24 clean the motor housing. Meanwhile, the exhaust fan 13 generates negative pressure at the suction duct, causing the dust brushed off by the exterior wall brush 19 and the interior wall brush 24 to be sucked into the filter box 14 for collection through the dust suction duct 20 and the connecting pipe 15.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
