Description

Technical Field

[0001] The present invention relates to the field of water pump production, and specifically to a water pump production device. Background Art

[0002] A water pump is a mechanical device for transporting liquids, widely used in multiple fields such as industry, agriculture, municipal administration, and households. A water pump generally includes components such as a driving part, an impeller, and a pump casing; the output end of the driving part is fixedly connected to the impeller. Driven by the driving part, the impeller rotates at high speed inside the pump casing, achieving the purpose of pumping liquid into the pump casing and discharging it from the pump casing.

[0003] When designing the impeller, according to the type and use of the pump, a casting or forging process is used to process an impeller made of metal material, or an impeller made of plastic material is processed by injection molding; for an impeller made of metal material processed by casting or forging, a keyway is reserved at the inner ring position of the installation hole of the impeller, and it is later installed on the output shaft of the driving part through a key. Generally, there is a clearance fit between the output shaft of the driving part and the installation hole of the metal material impeller, which facilitates the installation of the metal material impeller on the output end of the driving part; for an impeller made of plastic material processed by injection molding, there is generally an interference fit between the installation hole of the impeller and the output end of the driving part. During assembly, it is difficult to install the plastic material impeller on the output end of the driving part, and the installer needs to apply pressure on the impeller to successfully install the impeller. Currently, this installation method has the following problems: First, the efficiency is low and the labor intensity is high. Second, the installation success rate is relatively low.

Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and functions realized by the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0036] Refer to Figure 1 - Figure 10 , a water pump production equipment, including a turntable 1, the edge position of the lower surface of the turntable 1 is erected on the ground through a support frame 2, and a driving component is further provided on the lower surface of the turntable 1, and the driving component can drive the turntable 1 to rotate intermittently in the clockwise direction;

[0037] A plurality of pre-installation tables are uniformly arranged at the eccentric position on the upper surface of the turntable 1, and a motor is placed in the pre-installation table; a support body 3 is arranged in the middle of the turntable 1, and a material placing component is arranged on the support body 3, and the material placing component is used for placing the impeller 4 of the water pump, and a pressing component is arranged above the material placing component, and the pressing component can press the impeller 4 down and install it on the output shaft of the motor;

[0038] In this embodiment, the designed water pump production equipment is an assembly device in the water pump production process and is used for the assembly of the impeller 4 and the driving component. The motor described in this embodiment is the driving component;

[0039] In this embodiment, the designed driving assembly includes a servo motor, which is controlled by an operating system to execute. A gear is fixedly connected to the output end of the servo motor, and the gear meshes with a toothed ring. The toothed ring is arranged at the lower surface position of the turntable 1. The operating system controls the servo motor to rotate intermittently and can achieve the clockwise intermittent rotation of the turntable 1;

[0040] The motors are placed one by one on the pre-assembly table, and at the same time, the impellers 4 are placed one by one on the blanking assembly. Then, the turntable 1 synchronously transfers the motors and the impellers 4 to the pressing assembly position. The pressing assembly pushes the impeller 4 towards the output end direction of the motor. The mounting hole on the impeller 4 is opposite to the output end of the motor. Finally, the impeller 4 is mounted on the output end of the motor; the settings of the pre-assembly table and the blanking assembly make the mounting holes of the impellers 4 opposite to the output ends of the motors one by one, and the setting of the pressing assembly enables the impeller 4 to be stably pressed on the output end of the motor, which helps to improve the assembly efficiency and the installation success rate. At the same time, the pressing assembly can ensure the downward movement stroke of each impeller 4, so that the mounting hole of the impeller 4 is sleeved on the designated part of the motor output end, improving the assembly quality.

[0041] Refer to Figure 1 - Figure 9 As shown in FIG. 13, the pre-assembly table includes a bottom plate 5 and a surrounding plate 6. The bottom plate 5 is fixedly connected to the turntable 1. The surrounding plate 6 is U-shaped and is arranged along the edge of the bottom plate 5, and the open end of the surrounding plate 6 faces outside the turntable 1; there is a first conveyor belt 7 outside the turntable 1, and a plurality of motors to be assembled are placed on the first conveyor belt 7. The end of the first conveyor belt 7 is arranged opposite to the open end of the surrounding plate 6; the motors are relatively heavy. If the motors are carried to the pre-assembly table position, the labor intensity is relatively large. By setting the first conveyor belt 7 adapted to the pre-assembly table, the labor intensity can be reduced. The first conveyor belt 7 pushes the motors towards the pre-assembly table. When the motors are about to be pushed to the pre-assembly table position, the staff holds the motors by hand and pushes the motors onto the bottom plate 5. During the supporting process, the motors are flexibly rotated according to the bottom of the motors, so that the bottom of the motors is opposite to the arc part of the surrounding plate 6, that is, the motors are moved to the designated position on the bottom plate 5, which helps the axis of the motor output end and the axis of the impeller 4 mounting hole to tend to be in the same axis state, improving the installation success rate of the motor and the impeller 4.

[0042] Refer to Figure 1 - Figure 8 As shown in FIGS. 20, a platform 8 is provided at the upper end of the support body 3. A plurality of notches 9 are evenly opened at the edge of the platform 8. The notches 9 are arranged opposite to the pre-assembly tables on the turntable 1 one by one, and a blanking assembly is installed at each notch 9 position;

[0043] Each of the blanking components includes a plurality of vertical rods 10, which are uniformly arranged along the edge of the notch 9. The vertical rods 10 vertically penetrate the platform 8. The upper ends of the vertical rods 10 are connected to the upper surface of the platform 8 by springs, and the lower ends of the vertical rods 10 are fixedly connected with arc-shaped placing tables 11. The middle of the placing table 11 is open and opposite to the mounting holes on the impeller 4. A second conveyor belt 12 is arranged outside the platform 8, and a plurality of impellers 4 to be assembled are placed on the second conveyor belt 12. The end of the second conveyor belt 12 is arranged opposite to the notch 9. The turntable 1 is divided into a plurality of stations, such as Figure 3 shown, from station one to station six. The second conveyor belt 12 is arranged at the position of station one, the first conveyor belt 7 is arranged at the position of station two, and the pressing component is arranged at the position opposite to station four. The impellers 4 are placed on the second conveyor belt 12, and the second conveyor belt 12 pushes the impellers 4 onto the placing tables 11. The motors are placed on the first conveyor belt 7, and the first conveyor belt 7 pushes the motors onto the bottom plate 5. Before the turntable 1 rotates, an impeller 4 is first placed on the placing table 11 at the position of station two to ensure that there is a corresponding motor placed on the bottom plate 5 below each impeller 4. The turntable 1 synchronously transfers the impellers 4 and the motors to the position of the pressing component, and the pressing component presses down the impellers 4 to press the impellers 4 onto the output ends of the motors, realizing the assembly of the impellers 4 and the motors.

[0044] Refer to Figure 1 - Figure 10 As shown in, a through hole 13 is opened at the axial position of the support body 3. A column body 14 is arranged in the through hole 13. The outer circle of the column body 14 is in clearance fit with the inner circle of the through hole 13. The lower end of the column body 14 is seated on the ground, and the upper end of the column body 14 is fixedly connected with an adapter plate. The end of the adapter plate is provided with a pressing component.

[0045] The pressing assembly includes a cylinder 15. The lower end of the cylinder block of the cylinder 15 is fixedly connected to the connecting plate. The output end of the cylinder 15 penetrates through the connecting plate, and a pressing block 16 is fixedly connected to the output end of the cylinder 15. A limiting groove is formed on the lower end surface of the pressing block 16, and the shape of the limiting groove is adapted to the shape of the installation hole position of the impeller 4. The turntable 1 synchronously transfers the impeller 4 and the motor to the position of the pressing assembly. Under the control of the operating system, the cylinder 15 drives the pressing block 16 to press down the impeller 4. The limiting groove on the lower end surface of the pressing block 16 sleeves on the protruding part in the middle of the upper end surface of the impeller 4. The impeller 4 is pressed down, and at the same time, the impeller 4 also presses down the placing table 11. The placing table 11 drives the vertical rod 10 to move downward and compresses the spring. The impeller 4 is installed on the motor. At this time, the weight of the motor is greater than the elastic force of the spring, and the placing table 11 remains stable. The turntable 1 continues to rotate, transfers the assembled motor and impeller 4 to the position of station five, and then removes the motor. The output end of the motor disengages from the opening of the placing table 11, and the impeller 4 also disengages from the placing table 11. At this time, the placing table 11 moves upward and resets under the elastic force of the connected spring. After that, the turntable 1 transfers the placing table 11 to the positions of station six and station one in sequence, and then the impeller 4 on the second conveyor belt 12 is pushed onto the placing table 11.

[0046] Refer to Figure 1 - Figure 10 , a plurality of cross bars 17 are fixedly connected to the outer circle of the upper end of the column 14. An adapter bar 18 is vertically fixedly connected to the end of each cross bar 17. A limiting bar 19 in an arc shape is fixedly connected to the lower end of the adapter bar 18. The limiting bar 19 is located on the upper surface of the placing table 11. The inner circle of the limiting bar 19 can adhere to the outer circle of the impeller 4. The opening position of the limiting bar 19 faces the second conveyor belt 12. The limiting bar 19 is fixedly connected to the upper end position of the column 14 through the cross bar 17 and the adapter bar 18. The inner circle of the limiting bar 19 adheres to the outer circle of the impeller 4 on the placing table 11. When the turntable 1 rotates instantaneously, the impeller 4 has a tendency to slide off the placing table 11, which may cause the displacement of the impeller 4, and the installation hole on the impeller 4 will not be aligned with the output end of the motor. By setting the limiting bar 19, the impeller 4 can be constrained to prevent the impeller 4 from shifting.

[0047] Refer to Figure 1 - Figure 5 , an arc-shaped limiting strip 20 is arranged at the inner side position of the upper surface of each placing table 11. The limiting strip 20 adheres to the outer circle of the impeller 4, and the limiting strip 20 and the limiting bar 19 can cooperate to constrain the impeller 4. When the second conveyor belt 12 pushes the impeller 4 onto the placing table 11, the outer circle of the impeller 4 is constrained by the limiting strip 20, so that the impeller 4 moves to the designated position, and then in cooperation with the limiting bar 19, the impeller 4 is stabilized on the placing table 11, which helps to improve the coaxiality of the axis of the installation hole of the impeller 4 and the axis of the output end of the motor, so that the impeller 4 can be smoothly pressed on the motor.

[0048] Refer to Figure 1 -Figure 10 Each of the bottom plates 5 is hollow inside, and a plurality of air holes 21 are formed on the upper surface of the bottom plate 5; a plurality of air inlets 22 are evenly formed on the lower surface of the turntable 1, and the air inlets 22 are in one-to-one communication with the inside of the bottom plate 5;

[0049] A gas supply cover plate 23 and a suction cover plate 24 are arranged on the lower surface of the turntable 1, and the upper end surfaces of the gas supply cover plate 23 and the suction cover plate 24 are attached to the lower surface of the turntable 1. A gas supply pipe 25 is communicated with the lower surface of the gas supply cover plate 23, and a suction pipe 26 is communicated with the lower end surface of the suction cover plate 24; the suction cover plate 24 is arranged opposite to the first station, the second station, the third station and the fourth station. The suction cover plate 24 is communicated with an external negative pressure pump through the suction pipe 26. After the motor is pushed onto the bottom plate 5, the air holes 21 on the bottom plate 5 are in a negative pressure state, and the air holes 21 adsorb the bottom of the motor, stabilizing the motor on the bottom plate 5 and preventing the motor from being thrown off the turntable 1 during the instantaneous rotation of the turntable 1; while the gas supply cover plate 23 is arranged at a position corresponding to the fifth station and the sixth station, and the gas supply cover plate 23 is communicated with an external air pump through the gas supply pipe 25. The air pump injects gas into the gas supply cover plate 23. At this time, the gas is discharged from the air holes 21 of the bottom plate 5 at the fifth station and the sixth station. At the fifth station, the gas acts on the motor to be removed, forming an air film between the lower end surface of the motor and the upper surface of the bottom plate 5, facilitating the sliding removal of the motor; at the sixth station, the gas is discharged from the air holes 21, flushing and discharging foreign matters on the upper surface of the bottom plate 5 to prevent foreign matters from accumulating inside the bottom plate 5 and affecting the placement position of the motor.

[0050] Refer to Figure 1 - Figure 9 A rectangular opening 27 is formed in the arc-shaped part of each of the surrounding plates 6; a plurality of convex parts 28 are evenly arranged on the inner ring of the through hole 13, and a through opening 29 is formed inside the convex part 28. One end of the through opening 29 is communicated with the rectangular opening 27, and the other end of the through opening 29 is opposite to the outer circle of the column 14;

[0051] A chute 30 is radially formed on the surface of the cylinder 14. A slider 31 is arranged in the chute 30. The inner end of the slider 31 is connected to the bottom of the chute 30 through a compression spring. An air jet port 32 is formed on the outer end face of the slider 31. The air jet port 32 is opposite to the other port of the through port 29. A vertical hole 33 is formed on the upper surface of the slider 31. The vertical hole 33 communicates with the air jet port 32. An air duct 34 is arranged inside the cylinder 14. The upper port of the air duct 34 penetrates upward through the upper end face of the cylinder 14 and is connected with a hose 35. The lower port of the air duct 34 penetrates to the top surface of the chute 30. The slider 31 arranged on the cylinder 14 corresponds to the position of the sixth station. When the turntable 1 rotates, the convex part 28 on the inner ring of the through hole 13 presses on the slider 31, squeezing the slider 31 deep into the chute 30. At this time, the vertical hole 33 on the slider 31 communicates with the lower port of the air duct 34. The gas flows sequentially along the hose 35, the air duct 34, the vertical hole 33 and the air jet port 32, and is discharged from the position of the through port 29. The gas impacts the foreign objects on the bottom plate 5, thoroughly cleaning the foreign objects on the bottom plate 5.

[0052] Refer to Figure 1 - Figure 4 A third conveyor belt 36 is further arranged outside the turntable 1. The end of the second conveyor belt 12 is arranged opposite to the open end of the enclosure 6. The arranged third conveyor belt 36 corresponds to the position of the fifth station. When the assembled impeller 4 and the motor are transferred to the position of the fifth station, the motor is pushed onto the third conveyor belt 36, facilitating the staff to remove the motor.

[0053] Refer to Figure 9 Each convex part 28 is in an isosceles trapezoid shape; the outer end of the slider 31 is also arranged in an isosceles trapezoid shape. Due to the shapes of the convex part 28 and the slider 31, when the convex part 28 moves to the position of the slider 31, the inclined surface on the convex part 28 and the inclined surface on the slider 31 are mutually pressed, and the slider 31 is pushed into the chute 30, ensuring the smooth sliding of the slider 31.

[0054] Working principle: In this embodiment, the designed water pump production equipment is an assembly equipment in the water pump production process and is used for the assembly of the impeller 4 and the driving component. The motor described in this embodiment is the driving component.

[0055] The driving assembly designed in this embodiment includes a servo motor. The servo motor is controlled and executed by an operating system. A gear is fixedly connected to the output end of the servo motor. The gear meshes with a toothed ring. The toothed ring is arranged at the lower surface position of the turntable 1. The operating system controls the servo motor to rotate intermittently, and can realize the clockwise intermittent rotation of the turntable 1.

[0056] Place the motors one by one on the pre-assembly table. At the same time, place the impellers 4 one by one on the material placing assembly. Then, the turntable 1 synchronously transfers the motor and the impeller 4 to the position of the pressing assembly. The pressing assembly pushes the impeller 4 towards the output end of the motor. The mounting holes on the impeller 4 are opposite to the output end of the motor. Finally, the impeller 4 is mounted on the output end of the motor. The settings of the pre-assembly table and the material placing assembly make the mounting holes of the impeller 4 correspond to the output ends of the motors one by one. And the setting of the pressing assembly enables the impeller 4 to be stably pressed on the output end of the motor, which helps to improve the assembly efficiency and the installation success rate. At the same time, the pressing assembly can ensure the downward movement stroke of each impeller 4, so that the mounting hole of the impeller 4 is sleeved on the specified part of the output end of the motor, improving the assembly quality.

[0057] The motors are relatively heavy. If the motors are carried to the position of the pre-assembly table, the labor intensity is relatively large. However, with the setting of the first conveyor belt 7 adapted to the pre-assembly table, the labor intensity can be reduced. The first conveyor belt 7 pushes the motors towards the pre-assembly table. When the motors are about to be pushed to the position of the pre-assembly table, the staff holds the motors by hand and pushes the motors onto the bottom plate 5. During the supporting process, the motors are flexibly rotated according to the bottom of the motors, so that the bottom of the motors is opposite to the arc part of the enclosing plate 6, that is, the motors are moved to the specified position on the bottom plate 5. This helps the axis of the output end of the motor and the axis of the mounting hole of the impeller 4 to tend to be in the coaxial state, improving the installation success rate of the motor and the impeller 4.

[0058] The turntable 1 is divided into multiple workstations, such as Figure 3 shown, from workstation one to workstation six. The second conveyor belt 12 is set at the position of workstation one, the first conveyor belt 7 is set at the position of workstation two, and the pressing assembly is set at the position opposite to workstation four. The impellers 4 are placed on the second conveyor belt 12, and the second conveyor belt 12 pushes the impellers 4 onto the placing table 11. The motors are placed on the first conveyor belt 7, and the first conveyor belt 7 pushes the motors onto the bottom plate 5. Before the turntable 1 rotates, place an impeller 4 on the placing table 11 at the position of workstation two to ensure that there is a corresponding motor placed on the bottom plate 5 under each impeller 4. The turntable 1 synchronously transfers the impeller 4 and the motor to the position of the pressing assembly, and the pressing assembly presses down the impeller 4 to press the impeller 4 on the output end of the motor, realizing the assembly of the impeller 4 and the motor.

[0059] The turntable 1 synchronously transfers the impeller 4 and the motor to the position of the pressing assembly. Under the control of the operating system, the cylinder 15 drives the pressing block 16 to press down the impeller 4. The limiting groove on the lower end face of the pressing block 16 is sleeved on the protruding part in the middle of the upper end face of the impeller 4. The impeller 4 is pressed down. At the same time, the impeller 4 also presses down the placement table 11. The placement table 11 drives the vertical rod 10 to move downward and compress the spring. The impeller 4 is installed on the motor. At this time, the weight of the motor is greater than the elastic force of the spring, and the placement table 11 remains stable. The turntable 1 continues to rotate, transfers the assembled motor and impeller 4 to the position of station five, and then removes the motor. The output end of the motor disengages from the opening of the placement table 11, and the impeller 4 also disengages from the placement table 11. At this time, under the elastic force of the spring connected to the placement table 11, the placement table 11 moves upward to reset. Then, the turntable 1 transfers the placement table 11 to the positions of station six and station one in sequence, and then the impeller 4 on the second conveyor belt 12 is pushed onto the placement table 11;

[0060] The upper end position of the column 14 is fixedly connected to the limiting rod 19 through the cross bar 17 and the connecting rod 18. The inner circle of the limiting rod 19 adheres to the outer circle of the impeller 4 on the placement table 11. When the turntable 1 rotates instantaneously, the impeller 4 has a tendency to slide off the placement table 11, which may cause the displacement of the impeller 4, and the mounting hole on the impeller 4 will not be aligned with the output end of the motor. By setting the limiting rod 19, the impeller 4 can be constrained to prevent the impeller 4 from shifting;

[0061] When the second conveyor belt 12 pushes the impeller 4 onto the placement table 11, the outer circle of the impeller 4 is constrained by the limiting strip 20, so that the impeller 4 moves to the specified position. Then, in cooperation with the limiting rod 19, the impeller 4 is stabilized on the placement table 11, which helps to improve the coaxiality of the axis of the mounting hole of the impeller 4 and the axis of the output end of the motor, so that the impeller 4 can be smoothly pressed on the motor;

[0062] The suction hood plate 24 is arranged opposite to station one, station two, station three and station four. The suction hood plate 24 is connected to an external negative pressure pump through a suction pipe 26. After the motor is pushed onto the bottom plate 5, the air holes 21 on the bottom plate 5 are in a negative pressure state, and the air holes 21 adsorb the bottom of the motor to stabilize the motor on the bottom plate 5 and prevent the turntable 1 from throwing the motor off the turntable 1 during instantaneous rotation; The air supply hood plate 23 is arranged at positions corresponding to station five and station six. The air supply hood plate 23 is connected to an external air pump through an air supply pipe 25. The air pump injects gas into the air supply hood plate 23. At this time, the gas is discharged from the air holes 21 on the bottom plate 5 at station five and station six. At station five, the gas acts on the motor to be removed, forming an air film between the lower end face of the motor and the upper surface of the bottom plate 5, which facilitates the sliding removal of the motor; At station six, the gas is discharged from the air holes 21, and the foreign matters on the upper surface of the bottom plate 5 are flushed and discharged to prevent foreign matters from accumulating in the bottom plate 5 and affecting the placement position of the motor;

[0063] A slider 31 is arranged on the cylinder 14 corresponding to the position of the sixth station. When the turntable 1 rotates, the convex part 28 on the inner ring of the through hole 13 presses on the slider 31, squeezing the slider 31 deep into the chute 30. At this time, the vertical hole 33 on the slider 31 is communicated with the lower port of the air duct 34, and the gas flows successively along the hose 35, the air duct 34, the vertical hole 33 and the jet port 32, and is discharged from the position of the through port 29. The gas impacts the foreign matters on the bottom plate 5, thoroughly cleaning the foreign matters on the bottom plate 5;

[0064] The arranged third conveyor belt 36 is opposite to the position of the fifth station. When the assembled impeller 4 and the motor are transferred to the position of the fifth station, the motor is pushed onto the third conveyor belt 36, facilitating the staff to remove the motor.
