Technical Field

[0001] This utility model relates to the field of automation equipment technology in automobile manufacturing, specifically to an automatic PIN pin press-fitting device for automobile water pump stators. Background Technology

[0002] The stator of an automotive water pump is a stationary component in the water pump motor, mainly composed of a stator core and windings. Its core function is to convert electrical energy into mechanical energy to drive the water pump rotor to rotate, thereby achieving the circulation and discharge of coolant. The stator interacts with the rotor through the electromagnetic field generated by the windings, providing continuous power and ensuring the stable operation of the engine cooling system. Its application is widespread in automotive engine cooling systems, directly affecting the efficiency, energy consumption, and reliability of the water pump, and it is a key component ensuring normal heat dissipation of the vehicle.

[0003] In the manufacturing process of automotive water pump stators, pin pressing is a crucial step to ensure the stability of the stator's electrical connection and the subsequent normal operation of the water pump.

[0014] 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.

[0015] Please see Figure 1-6 This utility model provides a technical solution: an automatic PIN pin pressing device for automotive water pump stators, comprising a workbench 1, a mounting frame 2 fixedly mounted on the top rear side of the workbench 1, a mounting plate 3 fixedly mounted on the top front side of the mounting frame 2, a mounting plate 4 slidably mounted on the front side of the mounting plate 3, a cylinder 5 fixedly mounted on the top of the mounting plate 3, the bottom output shaft end of the cylinder 5 fixedly connected to the top of the mounting plate 4, a lifting block 7 slidably mounted on the front middle of the mounting plate 4, a cylinder 6 fixedly mounted on the top of the front side of the mounting plate 4, the bottom output shaft end of the cylinder 6 fixedly connected to the top of the lifting block 7, a fixing plate 8 fixedly mounted on the bottom of the front side of the mounting plate 4, a PIN pin feeding assembly mounted on the front side of the fixing plate 8, a PIN pin pressing assembly mounted between the lifting block 7 and the fixing plate 8, and a stator feeding assembly disposed below the fixing plate 8.

[0016] When this automatic PIN press-fitting equipment for automotive water pump stators is in operation, the entire equipment is first supported by the workbench 1. The mounting bracket 2 fixed to the rear of the top provides a mounting carrier for the mounting plate 3. The mounting plate 4, which is slidably mounted on the front of the mounting plate 3, can move up and down along the mounting plate 3 under the drive of the top cylinder 5, thereby adjusting the overall height of the mounting plate 4 and subsequent related components to prepare for the position of the stator feeding assembly. Then, the fixing plate 8 fixed to the bottom of the front of the mounting plate 4 serves as the mounting base for the PIN feeding assembly. The PIN feeding assembly can... The PIN feeding is completed. At the same time, the lifting block 7, which is slidably installed in the middle of the front side of the mounting plate 2 4, can slide up and down along the mounting plate 2 4 under the drive of the top cylinder 2 6. When the lifting block 7 moves downward, the PIN pressing assembly installed between it and the fixed plate 8 will be triggered, thereby pressing the PINs fed by the PIN feeding assembly to the designated position. Meanwhile, the stator feeding assembly set below the fixed plate 8 is responsible for feeding the stator 9, which is to be pressed with PINs, to the bottom of the PIN pressing assembly, and finally completing the automatic pressing process of the stator 9 with PINs.

[0017] The PIN feeding assembly includes a pressing block 16, which is fixedly installed on the front side of the fixed plate 8. A feeding plate 28 is fixedly installed on the right side of the pressing block 16. A feeding groove 34 is opened on the front side of the feeding plate 28. A PIN chain 33 is slidably connected inside the feeding groove 34. A feeding port 32 is also fixedly installed on the right side of the feeding plate 28. A conveying mechanism and an anti-backward mechanism are respectively installed on the left and right sides of the feeding plate 28.

[0018] The conveying mechanism includes a cylinder 30, which is fixedly installed in the middle of the rear side of the feed plate 28. A sliding block 29 is slidably sleeved on the left side of the feed plate 28. The output shaft end of the cylinder 30 is fixedly connected to the right rear side of the sliding block 29. A rotating plate 35 is rotatably installed in the middle of the front side of the sliding block 29. A rod 37 is fixedly connected to the rear left side of the rotating plate 35. The rear end of the rod 37 abuts against the inner wall of the feed trough 34. A spring groove 39 is opened in the right front side of the sliding block 29. A spring 41 is installed inside the spring groove 39. The front end of the spring 41 abuts against the rear right side of the rotating plate 35.

[0019] The anti-reverse mechanism includes a fixed block 31, which is fixedly installed on the right front side of the feed plate 28. A rotating plate 36 is rotatably installed on the front middle of the fixed block 31. A plug rod 38 is fixedly connected to the left rear side of the rotating plate 36. The rear end of the plug rod 38 abuts against the inner wall of the feed groove 34. A spring groove 40 is provided on the front right side of the fixed block 31. A spring 42 is provided inside the spring groove 40. The front end of the spring 42 abuts against the right rear side of the rotating plate 36.

[0020] When the PIN feeding assembly is working, the pressing block 16 is first fixed to the front side of the fixed plate 8. The feeding plate 28 fixed to its right side is the core of the PIN feeding. The PIN chain 33 can slide in the feeding groove 34 opened on the front side of the feeding plate 28. The PIN chain 33 to be fed enters the feeding groove 34 through the feeding port 32 fixed to the right side of the feeding plate 28. Then, the output shaft of the cylinder 30 fixed to the middle of the rear side of the feeding plate 28 extends and retracts, driving the sliding block 29 slidably sleeved on the left side of the feeding plate 28 to move left and right. When the sliding block 29 moves, the rotating plate 35 rotatably installed in the middle of its front side moves together. The spring force of the spring 41 in the spring groove 39 of the insert rod 37 fixed to the rear left side of the rotating plate 35 is... Under the action of the spring, the pin chain 33 is always pressed against the inner wall of the feed trough 34, thereby pushing the pin chain 33 to the left along the feed trough 34. At the same time, since the rotating plate 36 is rotatably installed on the front side of the fixing block 31 fixed on the right side of the feed plate 28, the insertion rod 38 fixed on the rear left side of the rotating plate 36 is pressed against the inner wall of the feed trough 34 under the elastic force of the spring 42 in the spring groove 40. When the pin chain 33 is conveyed to the left, the insertion rod 38 is pushed forward, thereby compressing the spring 42. When the pin chain 33 is conveyed once, the insertion rod 38 is pushed against the pin chain 33 again under the push of the spring 42, preventing it from retreating due to external force, and finally realizing the stable and orderly conveying of the pin chain 33.

[0021] The PIN pin pressing assembly includes a mounting block 25, which is fixedly mounted on the front side of the pressing block 16. A rotating plate 24 is rotatably mounted on the rear center of the mounting block 25. A circular groove 19 is formed inside the top side of the mounting block 25. A push rod 21 passes through the rear side of the circular groove 19. The rear end of the push rod 21 abuts against the front top of the rotating plate 24. A limiting plate 22 is also fixedly sleeved on the push rod 21. A spring 20 is provided inside the front side of the circular groove 19. The rear end of the spring 20 abuts against the front side of the limiting plate 22. The upper and lower sides of the pressing block 16 pass through the groove. A slot 23 is provided, and the left end of the feed groove 34 is connected to the slot 23. A sliding groove 26 is provided in the middle of the front side of the pressing block 16, and the sliding groove 26 is connected to the slot 23. A slider 27 is slidably connected on the sliding groove 26. The front end of the slider 27 is provided with a sliding groove. A sliding rod is fixedly connected to the bottom of the rotating plate 24 and is movably connected in the sliding groove. An inclined block 17 and an insert plate 18 are fixedly connected to the front and rear sides of the bottom of the lifting block 7, respectively. The bottom inclined surface of the inclined block 17 abuts against the top of the rotating plate 24, and the insert plate 18 is slidably connected inside the slot 23.

[0022] When the PIN pin pressing assembly is working, firstly, since the mounting block 25 is fixed to the front side of the pressing block 16, the rotating plate 24 can rotate in the middle of the rear side of the mounting block 25. In the circular groove 19 inside the top side of the mounting block 25, the rear end of the push rod 21 abuts against the front top of the rotating plate 24, and the push rod 21 cooperates with the spring 20 in the circular groove 19 through the limiting plate 22. The elastic force of the spring 20 can generate a rearward pushing force on the push rod 21. At the same time, the slot 23 penetrating the upper and lower sides of the pressing block 16 is connected to the left end of the feed groove 34, and the PIN pin chain 33 conveyed by the feed groove 34 can enter the slot 23. The sliding groove 26 in the middle of the front side of the pressing block 16 is connected to the slot 23. The slider 27 slides on the groove 26, and the sliding rod at the bottom of the rotating plate 24 is movably connected in the sliding groove of the slider 27. When the lifting block 7 moves downward under the drive, the inclined blocks 17 and the insert plate 18 on the front and rear sides of its bottom move downward synchronously. The inclined surface at the bottom of the inclined block 17 presses against the top of the rotating plate 24, pushing the rotating plate 24 to rotate around the middle of the rear side of the mounting block 25. When the rotating plate 24 rotates, the bottom sliding rod drives the slider 27 to slide along the groove 26 towards the slot 23. At the same time, the insert plate 18 at the bottom of the lifting block 7 slides into the slot 23 and cooperates with the slider 27 to apply pressure to the PIN pin in the slot 23, finally completing the single pressing operation of the PIN pin.

[0023] The stator feeding assembly includes a mounting plate 311, which is fixedly mounted on the top side of the workbench 1. A mounting frame 12 is slidably mounted on the front side of the mounting plate 311. A cylinder 314 is provided on the bottom side of the mounting frame 12. The cylinder 314 is fixedly mounted on the top side of the workbench 1. The top output shaft end of the cylinder 314 is fixedly connected to the bottom of the mounting frame 12. A feeding plate 13 is provided on the top side of the mounting frame 12. A positioning rod 10 is fixedly connected to the middle of the top side of the feeding plate 13. A stator 9 is slidably sleeved on the positioning rod 10. A drive motor 15 is fixedly mounted on the top and bottom sides of the mounting frame 12. The output shaft end of the drive motor 15 rotates out of the top side of the mounting frame 12 and is fixedly connected to the bottom side of the feeding plate 13.

[0024] When the stator feeding assembly is working, the mounting plate 11 is fixed to the top side of the workbench 1, and the mounting frame 12 can slide in front of the mounting plate 11. The cylinder 14 on the bottom side of the mounting frame 12 is fixed to the top side of the workbench 1, and its top output shaft is fixedly connected to the bottom of the mounting frame 12. By extending and retracting the output shaft of the cylinder 14, the mounting frame 12 can be moved up and down along the mounting plate 11, thereby adjusting the height of the mounting frame 12. The feeding plate 13 on the top side of the mounting frame 12 is used to support the stator 9, and the positioning rod 10 fixed in the middle of the top side of the feeding plate 13 allows the stator 9 to slide. The stator 9 is initially positioned by fitting it onto the mounting frame 12, preventing it from shifting during placement. When the angle of the stator 9 needs to be adjusted to match the PIN pin pressing position, the drive motor 15 fixed to the top and bottom of the mounting frame 12 starts, and its output shaft rotates and extends out of the top side of the mounting frame 12, driving the feeding plate 13 to rotate. The feeding plate 13 then drives the positioning rod 10 and the stator 9 fitted on it to rotate synchronously until the stator 9 is adjusted to the appropriate pressing angle, thus completing the feeding, positioning and angle adjustment of the stator 9, preparing for the subsequent PIN pin pressing process.

[0025] Working Principle: When this automatic PIN press-fitting equipment for automotive water pump stators is in operation, the entire equipment is first supported by the workbench 1. The mounting bracket 2 fixed to the rear of the top provides a mounting carrier for the mounting plate 3. The mounting plate 4, which is slidably mounted on the front of the mounting plate 3, can move up and down along the mounting plate 3 under the drive of the top cylinder 5, thereby adjusting the overall height of the mounting plate 4 to prepare for the feeding position of the stator 9. Then, the fixing plate 8 fixed to the bottom of the front of the mounting plate 4 serves as the mounting base for PIN feeding. The pressing block 16 is fixed to the front of the fixing plate 8, and the feeding plate 28 fixed to its right is the core of PIN conveying. The PIN chain 33 can slide in the feeding groove 34 opened on the front of the feeding plate 28. The PIN chain 33 to be conveyed enters the feeding groove 34 through the feeding port 32 fixed to the right of the feeding plate 28. Then, the output shaft of the cylinder 30 fixed in the middle of the rear of the feeding plate 28 extends and retracts, driving the left side of the feeding plate 28 to slide. The sliding block 29 moves left and right. When the sliding block 29 moves, the rotating plate 35, which is rotatably mounted on its front center, moves along with it. The insert rod 37, which is fixed on the rear left side of the rotating plate 35, is always in contact with the inner wall of the feed groove 34 under the elastic force of the spring 41 in the spring groove 39, thereby pushing the PIN needle chain 33 to the left along the feed groove 34. At the same time, since the rotating plate 36 is rotatably mounted on the front side of the fixing block 31 fixed on the front right side of the feed plate 28, the rotating plate 36 rotates... The insertion rod 38, fixed to the rear left side of plate 36, abuts against the inner wall of feed groove 34 under the elastic force of spring 32 in spring groove 2 40. When the PIN needle chain 33 is conveyed to the left, the insertion rod 38 is pushed forward, thereby compressing spring 32. When the PIN needle chain 33 is conveyed once, the insertion rod 38 abuts against the PIN needle chain 33 again under the push of spring 32, preventing it from retreating due to external force, and finally achieving stable and orderly conveying of PIN needle chain 33. Simultaneously, the lifting block 7, which is slidably installed in the middle of the front side of the mounting plate 24, can slide up and down along the mounting plate 24 under the drive of the top cylinder 26. When the lifting block 7 moves downward, since the mounting block 25 is fixed in front of the pressing block 16, the rotating plate 14 can rotate in the middle of the rear side of the mounting block 25. In the circular groove 19 inside the top side of the mounting block 25, the rear end of the push rod 21 abuts against the front top of the rotating plate 14, and the push rod 21 cooperates with the spring 20 in the circular groove 19 through the limiting plate 22. The elastic force of the spring 20 can generate a backward thrust on the push rod 21. At the same time, the slot 23 penetrating the upper and lower sides of the pressing block 16 is connected to the left end of the feeding groove 34. The PIN needle chain 33 conveyed by the feeding groove 34 can enter the slot 23 for pressing. The groove 26 in the middle of the front side of block 16 is connected to slot 23. The slider 27 slides on the groove 26, and the sliding rod at the bottom of the rotating plate 24 is movably connected in the sliding groove of the slider 27. When the lifting block 7 moves downward under the drive, the inclined block 17 and the insert plate 18 on the front and rear sides of its bottom move downward synchronously. The inclined surface at the bottom of the inclined block 17 presses against the top of the rotating plate 24, pushing the rotating plate 24 to rotate around the middle of the rear side of the mounting block 25. When the rotating plate 24 rotates, the bottom sliding rod drives the slider 27 to slide along the groove 26 towards the slot 23. At the same time, the insert plate 18 at the bottom of the lifting block 7 slides into the slot 23 and cooperates with the slider 27 to apply pressure to the PIN pin in the slot 23, finally completing the single pressing operation of the PIN pin. Furthermore, since mounting plate 3 11 is fixed to the top side of workbench 1, mounting frame 12 can slide in front of mounting plate 3 11. Cylinder 3 14 on the bottom side of mounting frame 12 is fixed to the top side of workbench 1, and its top output shaft end is fixedly connected to the bottom of mounting frame 12. Through the extension and retraction of the output shaft of cylinder 3 14, mounting frame 12 can be moved up and down along mounting plate 3 11, thereby adjusting the height of mounting frame 12. The feeding plate 13 on the top side of mounting frame 12 is used to support stator 9. The positioning rod 10 fixed in the middle of the top side of feeding plate 13 allows stator 9 to slide onto it, achieving the initial positioning of stator 9. To prevent the stator 9 from shifting during placement, when the angle of the stator 9 needs to be adjusted to match the PIN pin pressing position, the drive motor 15 fixed on the top and bottom side of the mounting frame 12 starts, and its output shaft end rotates and extends out of the top side of the mounting frame 12, driving the feeding plate 13 to rotate. The feeding plate 13 then drives the positioning rod 10 and the stator 9 sleeved on it to rotate synchronously until the stator 9 is adjusted to the appropriate pressing angle, thus completing the feeding, positioning and angle adjustment of the stator 9, preparing for the subsequent PIN pin pressing process, and finally completing the automatic PIN pin pressing process of the stator 9.
