Description

Technical Field

[0001] The utility model relates to the technical field of plastic encapsulated motor production equipment, in particular to a double-station plastic encapsulated stator cavity cleaning device. Background Art

[0002] A plastic encapsulated motor uses plastic encapsulation technology to integrally encapsulate the stator core, winding, etc. of the motor with engineering plastics, and can cancel the traditional motor stator insulation treatment process and the metal casing of ordinary motors. At present, after the plastic encapsulated stator is injection molded and the injection molding machine is opened, a circle of protruding and hardened plastic encapsulated residue will appear at the mold clamping line position of the plastic encapsulated stator. This circle of residue needs to be manually filed with a file, and after filing, the plastic encapsulated stator is placed in a cavity cleaning machine to clean the inner cavity of the plastic encapsulated stator and remove the plastic encapsulated residue on the inner wall of the stator to prevent abnormal noise caused by the rotor rubbing against the plastic encapsulated residue after assembly.

[0003] At present, the existing cavity cleaning machines can only perform inner cavity cleaning on plastic encapsulated stators of specific sizes. When the workshop produces plastic encapsulated stators of different size batches, it is necessary to replace accessories such as the grinding heads of the cavity cleaning machine to adapt to plastic encapsulated stators with different inner cavity sizes. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a double-station plastic encapsulated stator cavity cleaning device.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A double-station plastic encapsulated stator cavity cleaning device includes a frame. A base plate is arranged at the top of the frame. Two vertical columns are vertically arranged on both sides of the base plate. A first mounting plate is jointly arranged on the four vertical columns. A second mounting plate is slidably arranged above the first mounting plate on the four vertical columns. Two placing rings for placing plastic encapsulated stators are rotatably arranged on the first mounting plate. Two power components are also arranged on the first mounting plate respectively for driving the corresponding placing rings to rotate. Pressing components are respectively arranged on the second mounting plate corresponding to the placing rings. A top plate is jointly arranged at the tops of the four vertical columns. A lifting component is arranged on the top plate for driving the second mounting plate to lift. A fixed seat is arranged on one side of the frame. A slide rail is horizontally arranged on the side of the fixed seat facing the inside of the frame. Slide seats are slidably arranged at both ends of the slide rail. Two driving components are arranged on the fixed seat respectively for driving the corresponding slide seats to slide. A rotating shaft is vertically rotatably arranged on the slide seat. The upper end of the rotating shaft passes through the middle of the placing ring and is provided with a grinding head. A rotating component for driving the rotating shaft to rotate is arranged on the slide seat.

[0006] By adopting the above technical solution, a frame, a substrate, a placement ring, a power assembly, a pressing assembly, a lifting assembly, a driving assembly and a rotating assembly are provided. The plastic-sealed stator to be cleaned is placed on the placement ring, and then the second mounting plate is driven to descend by the lifting assembly, so that the pressing assembly presses the plastic-sealed stator on the placement ring. The power assembly is used to drive the placement ring to rotate, so that the plastic-sealed stator rotates. Then, the rotating assembly is used to drive the rotating shaft to rotate, driving the grinding head to rotate. Subsequently, the driving assembly is used to drive the sliding seat to move, so as to drive the grinding head to move until the grinding head contacts the inner wall of the plastic-sealed stator, cleaning the inner wall of the plastic-sealed stator. When cleaning plastic-sealed stators with different sizes of inner cavities, it is only necessary to control the sliding distance of the sliding seat to control the contact between the grinding head and the inner wall of the plastic-sealed stator, so that it is not necessary to replace accessories such as the grinding head of the cavity cleaning machine to adapt to plastic-sealed stators with different sizes of inner cavities.

[0007] Further, a strip-shaped opening is formed in the fixing seat along the length direction of the slide rail. The driving assembly includes a fixing plate vertically arranged outside the fixing seat. A cylinder is horizontally arranged on the fixing plate. A connecting plate which passes through the strip-shaped opening and is connected to the piston rod of the cylinder is arranged on the sliding seat. A through hole is formed in the connecting plate. A vertical plate is vertically arranged in the middle of the fixing seat. A threaded rod is horizontally arranged on the vertical plate. The diameter of the threaded rod is smaller than the diameter of the through hole and the end part thereof passes through the through hole. An adjusting nut is spirally arranged on the rod body of the threaded rod on the side of the connecting plate away from the cylinder.

[0008] By adopting the above technical solution, the strip-shaped opening, the cylinder, the connecting plate, the through hole, the vertical plate, the threaded rod and the adjusting nut are provided. The cylinder is used to drive the connecting plate to move, driving the sliding seat to move. The position of the adjusting nut on the threaded rod is adjusted to limit the sliding distance of the connecting plate and the sliding seat, so as to limit the position of the grinding head, avoiding the grinding head moving too far and scratching the inner wall of the plastic-sealed stator.

[0009] Further, the rotating assembly includes a driving rotating motor vertically arranged on the sliding seat. The output shaft of the rotating motor faces upward and is provided with a first belt pulley. A second belt pulley is arranged at the lower end of the rotating shaft. The first belt pulley and the second belt pulley are connected by a first transmission belt.

[0010] By adopting the above technical solution, the rotating motor, the first belt pulley, the second belt pulley and the first transmission belt are provided. The rotating motor drives the first belt pulley to rotate, and drives the second belt pulley to rotate through the first transmission belt, so as to drive the rotating shaft and the grinding head to rotate.

[0011] Further, the lifting assembly includes a lead screw vertically and rotatably arranged on the top plate. A lifting nut cooperating with the lead screw is arranged on the second mounting plate. A lifting motor is vertically arranged on the top plate. The output shaft of the lifting motor faces upward and is provided with a third pulley. The upper end of the lead screw passes through the top plate and is provided with a fourth pulley. The third pulley and the fourth pulley are connected by a second transmission belt.

[0012] By adopting the above technical solution, the lead screw, the lifting nut, the lifting motor, the third pulley, the fourth pulley and the second transmission belt are provided. The third pulley is driven to rotate by the lifting motor, and the fourth pulley is driven to rotate under the action of the second transmission belt, so as to drive the lead screw to rotate and drive the second mounting plate to lift.

[0013] Further, the pressing assembly includes two slide bars vertically and slidably arranged on the second mounting plate and arranged at intervals. The upper ends of the two slide bars are located above the second mounting plate and are provided with an upper connecting piece. The lower ends of the two slide bars are located below the second mounting plate and are provided with a lower connecting piece. The lower end of one of the slide bars passes through the lower connecting piece and is provided with a mounting block. A pressing seat is rotatably arranged on the lower side of the mounting block corresponding to the placing ring. A second compression spring is arranged on the rod body of the slide bar connected to the mounting block between the lower connecting piece and the second mounting plate. The upper end of the second compression spring is connected to the second mounting plate, and the lower end is connected to the lower connecting piece.

[0014] By adopting the above technical solution, the slide bar, the upper connecting piece, the lower connecting piece, the mounting block, the pressing seat and the second compression spring are provided. The lifting assembly drives the second mounting plate to descend, so that the pressing seat contacts the top of the plastic-sealed stator. When the mounting plate continues to descend, the second compression spring is compressed, ensuring that the plastic-sealed stator is continuously pressed. Since the pressing seat is rotatably arranged under the mounting block, when the plastic-sealed stator rotates, the pressing block rotates synchronously.

[0015] Further, the first mounting plate is slidably arranged on the vertical rod. A first compression spring is arranged on the rod body of the vertical rod between the first mounting plate and the base plate. The upper end of the first compression spring is connected to the first mounting plate, and the lower end is connected to the base plate. A first abutting rod is arranged upward on the top surface of the first mounting plate. A second abutting rod is vertically arranged on the bottom surface of the second mounting plate corresponding to the first abutting rod.

[0016] By adopting the above technical solution, the first compression spring, the first abutting rod and the second abutting rod are provided. During the downward movement of the second mounting plate, the first abutting rod contacts the second abutting rod, so that the distance between the first mounting plate and the second mounting plate is restricted. On the one hand, the compression degree of the second compression spring is restricted, and on the other hand, the first mounting plate is driven to descend, thereby driving the placement ring and the position of the plastic-sealed stator to descend. Furthermore, the grinding head extends into the plastic-sealed stator, cleaning the deep part of the inner cavity of the plastic-sealed stator, so that it is not necessary to replace accessories such as the grinding head of the cavity cleaning machine to adapt to plastic-sealed stators with different inner cavity sizes. During the downward movement of the first mounting plate, the first compression spring is compressed. When the cleaning of the plastic-sealed stator is completed, the lifting assembly drives the second mounting plate to rise, and the first compression spring loses the restriction and pushes the first mounting plate to reset.

[0017] Furthermore, a plurality of limiting rods are vertically and slidably arranged on the first mounting plate. The lower ends of the limiting rods are connected to the substrate, and the upper ends are located above the first mounting plate and are provided with limiting plates. Limiting blocks are slidably arranged on the limiting rods, and the tops of the limiting blocks are connected to the first mounting plate.

[0018] By adopting the above technical solution, the limiting rods, the limiting plates and the limiting blocks are provided. The limiting plate restricts the highest position of the first mounting plate. When the first mounting plate descends, the limiting block contacts the substrate, so that the limiting plate restricts the lowest position of the first mounting plate.

[0019] Furthermore, the power assembly includes a mounting seat arranged on the lower side of the first mounting plate. A power motor is vertically arranged on the mounting seat. The output shaft of the power motor faces upward and is provided with a driving wheel. The lower side of the placement ring is located on the lower side of the first mounting plate and is sleeved with a toothed ring, and the toothed ring meshes with the driving wheel.

[0020] By adopting the above technical solution, the mounting seat, the power motor, the driving wheel and the toothed ring are provided. The driving wheel is driven to rotate by the power motor, thereby driving the toothed ring to rotate, and further driving the placement ring to rotate.

[0021] Furthermore, a hole is vertically opened on the mounting seat. The lower end of the placement ring is rotatably arranged on the mounting seat. The hole and the placement ring are concentrically arranged and the diameter of the hole is smaller than the inner diameter of the placement ring. A connection box is arranged on the sliding seat. Openings are provided at both the bottom and the top of the connection box. The opening at the top of the connection box is connected to the hole through a bellows tube, and the opening at the bottom is used to connect to a vacuum cleaner.

[0022] By adopting the above technical solution, the connection box and the openings are provided. There is a gap between the rotating shaft and the placement ring. The debris removed from the inner wall of the plastic-sealed stator by the grinding head is sucked into the vacuum cleaner through the connection box and the bellows tube, ensuring the cleanliness of the device.

[0023] In summary, the utility model has the following beneficial effects: In this application, a frame, a substrate, a placement ring, a power assembly, a pressing assembly, a lifting assembly, a driving assembly, and a rotating assembly are provided. The plastic-sealed stator to be cleaned is placed on the placement ring, and then the second mounting plate is driven to descend by the lifting assembly, so that the pressing assembly presses the plastic-sealed stator on the placement ring. The power assembly is used to drive the placement ring to rotate, so that the plastic-sealed stator rotates. Then, the rotating assembly is used to drive the rotating shaft to rotate, driving the grinding head to rotate. Subsequently, the driving assembly is used to drive the sliding seat to move, so as to drive the grinding head to move until the grinding head contacts the inner wall of the plastic-sealed stator, cleaning the inner wall of the plastic-sealed stator. When cleaning plastic-sealed stators with different inner cavity sizes, only the sliding distance of the sliding seat needs to be controlled to control the contact between the grinding head and the inner wall of the plastic-sealed stator, so that it is not necessary to replace accessories such as the grinding head of the cavity cleaning machine to adapt to plastic-sealed stators with different inner cavity sizes.

Detailed implementation mode

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

[0032] As Figures 1-6 shown, the embodiment of the present application discloses a double-station plastic-sealed stator cavity cleaning device, including a frame 10, a power assembly 40, a placement ring 21, a pressing assembly 50, a lifting assembly 60, and a driving assembly 80. A base plate 11 is arranged at the top of the frame 10. Two vertical rods 12 are vertically arranged on both sides of the base plate 11. A first mounting plate 20 is jointly arranged on the four vertical rods 12. A second mounting plate 30 is jointly and slidably arranged above the first mounting plate 20 on the four vertical rods 12, so that the second mounting plate 30 can slide along the vertical rods 12. Two placement rings 21 are rotatably arranged on the first mounting plate 20 for placing plastic-sealed stators. Two power assemblies 40 are arranged on the first mounting plate 20, respectively used to drive the corresponding placement rings 21 to rotate, so as to drive the plastic-sealed stators to rotate. There are two pressing assemblies 50, and the two pressing assemblies 50 are respectively arranged corresponding to the placement rings 21 on the second mounting plate 30.

[0033] A top plate 13 is commonly provided at the tops of four vertical rods 12. A lifting assembly 60 is arranged on the top plate 13 and is used to drive the second mounting plate 30 to lift, so as to drive the pressing assembly 50 to descend and press the plastic-sealed stator on the placing ring 21. A fixed seat 70 is arranged on one side of the frame 10. A slide rail 71 is horizontally arranged on the side of the fixed seat 70 facing the inside of the frame 10. Slide seats 72 are slidably arranged at both ends of the slide rail 71. A rotating shaft 73 is vertically rotatably arranged on the slide seat 72. The upper end of the rotating shaft 73 passes through the middle of the placing ring 21 and a grinding head 74 is arranged. Specifically, when setting, the grinding head 74 adopts a wire brush. A rotating assembly 90 is arranged on the slide seat 72 and is used to drive the rotating shaft 73 to rotate, so as to drive the grinding head 74 to rotate. There are two driving assemblies 80, both of which are arranged on the fixed seat 70 and are respectively used to drive the corresponding slide seats 72 to slide. The driving assembly 80 drives the slide seat 72 to move, so as to drive the grinding head 74 to move until the grinding head 74 contacts the inner wall of the plastic-sealed stator, and the inner wall of the plastic-sealed stator is cleaned. When cleaning plastic-sealed stators with different inner cavity sizes of different sizes, only the sliding distance of the slide seat 72 needs to be controlled to control the contact between the grinding head 74 and the inner wall of the plastic-sealed stator, so that it is not necessary to replace accessories such as the grinding head 74 of the cavity cleaning machine to adapt to plastic-sealed stators with different inner cavity sizes.

[0034] Specifically, the lifting assembly 60 includes a lead screw 61 vertically rotatably arranged on the top plate 13. A lifting nut 62 matched with the lead screw 61 is arranged on the second mounting plate 30. The rotation of the lead screw 61 drives the lifting nut 62 and the second mounting plate 30 to lift. A lifting motor 63 is vertically arranged on the top plate 13. The output shaft of the lifting motor 63 faces upward and a third belt pulley 64 is arranged. The upper end of the lead screw 61 passes through the top plate 13 and a fourth belt pulley 65 is arranged. The third belt pulley 64 and the fourth belt pulley 65 are connected by a second transmission belt 66. The lifting motor 63 drives the third belt pulley 64 to rotate, and drives the fourth belt pulley 65 to rotate under the action of the second transmission belt 66, so as to drive the lead screw 61 to rotate and drive the second mounting plate 30 to lift.

[0035] The pressing assembly 50 includes two sliding rods 51 that are vertically slidably arranged on the second mounting plate 30 and are spaced apart. The upper ends of the two sliding rods 51 are located above the second mounting plate 30 and are provided with upper connecting pieces 52. The lower ends of the two sliding rods 51 are located below the second mounting plate 30 and are provided with lower connecting pieces 53 to ensure the stable connection of the two sliding rods 51. The lower end of one of the sliding rods 51 passes through the lower connecting piece 53 and is provided with a mounting block 54. A lower pressing seat 55 is rotatably arranged on the lower side of the mounting block 54 corresponding to the placement ring 21. The lifting assembly 60 drives the second mounting plate 30 to descend, so that the lower pressing seat 55 contacts the top of the plastic-sealed stator. Since the lower pressing seat 55 is rotatably arranged under the mounting block 54, when the plastic-sealed stator rotates, the lower pressing block rotates synchronously. Specifically, a linear bearing is vertically arranged on the second mounting plate 30, and the sliding rod 51 is slidably arranged on the second mounting plate 30 through the linear bearing. The bottom of the pressing plate contacts the top of the linear bearing. A second compression spring 56 is arranged on the rod body of the sliding rod 51 connected to the mounting block 54 between the lower connecting piece 53 and the second mounting plate 30. The upper end of the second compression spring 56 is connected to the second mounting plate 30, and the lower end is connected to the lower connecting piece 53. After the lower pressing seat 55 contacts the top of the plastic-sealed stator, the mounting plate continues to descend, causing the second compression spring 56 to be compressed, ensuring that the plastic-sealed stator is continuously pressed by the lower pressing seat 55 and ensuring the stable rotation of the plastic-sealed stator.

[0036] The power assembly 40 includes a mounting seat 41 arranged on the lower side of the first mounting plate 20. A power motor 42 is vertically arranged on the mounting seat 41. The output shaft of the power motor 42 faces upward and is provided with a driving wheel 43. A toothed ring 44 is sleeved on the lower side of the placement ring 21 and is located below the first mounting plate 20. The toothed ring 44 meshes with the driving wheel 43. By driving the driving wheel 43 to rotate through the power motor 42, the toothed ring 44 is driven to rotate, and then the placement ring 21 is driven to rotate.

[0037] The rotating assembly 90 includes a driving rotating motor 91 vertically arranged on the sliding seat 72. The output shaft of the rotating motor 91 faces upward and is provided with a first pulley 92. The lower end of the rotating shaft 73 is provided with a second pulley 93. The first pulley 92 and the second pulley 93 are connected by a first transmission belt 94. The rotating motor 91 drives the first pulley 92 to rotate, and uses the first transmission belt 94 to drive the second pulley 93 to rotate, thereby driving the rotating shaft 73 and the grinding head 74 to rotate to clean the inner wall of the plastic-sealed stator.

[0038] A strip-shaped opening 75 is formed in the fixing base 70 along the length direction of the sliding rail 71. The driving assembly 80 includes a fixing plate 86 vertically arranged outside the fixing base 70. A cylinder 82 is horizontally arranged on the fixing plate 86. A connecting plate 81 is arranged on the sliding seat 72, which passes through the strip-shaped opening 75 and is connected to the piston rod of the cylinder 82. The cylinder 82 drives the connecting plate 81 to move, driving the sliding seat 72 to move. A vertical plate 83 is vertically arranged in the middle of the fixing base 70. A threaded rod 84 is horizontally arranged on the vertical plate 83. A through hole is formed in the connecting plate 81. The diameter of the threaded rod 84 is smaller than the diameter of the through hole and its end passes through the through hole. An adjusting nut 85 is spirally arranged on the rod body of the threaded rod 84 on the side of the connecting plate 81 away from the cylinder 82. By adjusting the position of the adjusting nut 85 on the threaded rod 84, the sliding distance of the connecting plate 81 and the sliding seat 72 is restricted, thereby restricting the position of the grinding head 74 and preventing the grinding head 74 from moving too far and scratching the inner wall of the plastic-sealed stator. Specifically, only one vertical plate 83 is provided. A tension spring is arranged between the fixing plate 86 and the connecting plate 81 of another driving assembly 80 to improve the stability of the cylinder 82 driving the sliding seat 72 to slide.

[0039] During setting, the first mounting plate 20 is slidably arranged on the vertical rod 12. A first abutting rod 22 is upwardly arranged on the top surface of the first mounting plate 20. A second abutting rod 31 is vertically arranged on the bottom surface of the second mounting plate 30 corresponding to the first abutting rod 22. During the descending process of the second mounting plate 30, the first abutting rod 22 contacts the second abutting rod 31, restricting the distance between the first mounting plate 20 and the second mounting plate 30 and restricting the compression degree of the second compression spring 56. A first compression spring 14 is arranged on the rod body of the vertical rod 12 between the first mounting plate 20 and the substrate 11. The upper end of the first compression spring 14 is connected to the first mounting plate 20 and the lower end is connected to the substrate 11. When the second mounting plate 30 continues to descend, it drives the first mounting plate 20 to descend, thereby driving the positions of the placing ring 21 and the plastic-sealed stator to descend, and further causing the grinding head 74 to extend into the plastic-sealed stator to clean the deep part of the inner cavity of the plastic-sealed stator, so that it is not necessary to replace accessories such as the grinding head 74 of the cavity cleaning machine to adapt to plastic-sealed stators with different inner cavity sizes. During the descending process of the first mounting plate 20, the first compression spring 14 is compressed. When the cleaning of the plastic-sealed stator is completed, the lifting assembly 60 drives the second mounting plate 30 to rise, and the first compression spring 14 loses its restriction and pushes the first mounting plate 20 to reset. The lengths of the first abutting rod 22 and the second abutting rod 31 can be adjusted, so that the distance between the first mounting plate 20 and the second mounting plate 30 can be adjusted when the second mounting plate 30 presses down the first mounting plate 20 according to the height of the plastic-sealed stator.

[0040] During specific installation, a number of limiting rods 23 are vertically slidably arranged on the first mounting plate 20. The lower ends of the limiting rods 23 are connected to the base plate 11, and the upper ends are located above the first mounting plate 20 and are provided with limiting plates 24 to limit the highest position of the first mounting plate 20. A limiting block 25 is slidably arranged on the limiting rod 23. The top of the limiting block 25 is connected to the first mounting plate 20. When the first mounting plate 20 descends, the limiting block 25 contacts the base plate 11, so that the limiting plate 24 limits the lowest position of the first mounting plate 20. By changing the height of the limiting block 25, the distance that the grinding head 74 extends into the plastic-encapsulated stator can be changed.

[0041] A hole is vertically opened on the mounting seat 41. The lower end of the placing ring 21 is rotatably arranged on the mounting seat 41. The hole and the placing ring 21 are concentrically arranged and the diameter of the hole is smaller than the inner diameter of the placing ring 21. A connecting box 76 is arranged on the sliding seat 72. Openings are provided at both the bottom and the top of the connecting box 76. The opening at the top of the connecting box 76 is connected to the hole through a bellows tube 77, and the opening at the bottom is used to connect to a vacuum cleaner. There is a gap between the rotating shaft 73 and the placing ring 21. The debris removed from the inner wall of the plastic-encapsulated stator by the grinding head 74 is sucked into the vacuum cleaner through the connecting box 76 and the bellows tube 77, ensuring the cleanliness of the device. A sealing gasket is arranged on the pressing seat 55. When the pressing seat 55 contacts the top of the plastic-encapsulated stator, the sealing gasket blocks the holes at the top of the plastic-encapsulated stator to prevent the debris from floating out from the top of the plastic-encapsulated stator.

[0042] The working principle of a double-station plastic-encapsulated stator cavity cleaning device in this embodiment is as follows: Place the two plastic-encapsulated stators to be cleaned on the placing ring 21 respectively. Start the lifting motor 63 to drive the third pulley 64 to rotate. Under the action of the second transmission belt 66, drive the fourth pulley 65 and the lead screw 61 to rotate, and drive the second mounting plate 30 to descend until the pressing disc contacts the top of the plastic-encapsulated stator. Start the power motor 42 to drive the driving wheel 43 to rotate, thereby driving the toothed ring 44 to rotate, and then driving the placing ring 21 to rotate. Then start the rotating motor 91 to drive the first pulley 92 to rotate, and drive the second pulley 93, the rotating shaft 73, and the grinding head 74 to rotate through the first transmission belt 94. Subsequently, start the cylinder 82. The cylinder 82 drives the connecting plate 81, the sliding seat 72, the rotating shaft 73, and the grinding head 74 to move, so that the grinding head 74 contacts the inner wall of the plastic-encapsulated stator to clean the inner wall of the plastic-encapsulated stator. Then use the lifting motor 63 to drive the second mounting plate 30 to descend. At this time, the first abutting rod 22 contacts the second abutting rod 31, driving the first mounting plate 20 to descend, thereby driving the positions of the placing ring 21 and the plastic-encapsulated stator to descend, and further enabling the grinding head 74 to extend into the plastic-encapsulated stator to clean the deep part of the inner cavity of the plastic-encapsulated stator, so that it is not necessary to replace accessories such as the grinding head 74 of the cavity cleaning machine to adapt to plastic-encapsulated stators with different inner cavity sizes.
