Description

Technical Field

[0001] This application relates to the field of shaft-mounting technology for shaft parts, and in particular to a preload module and an automatic impeller shaft-mounting device using the preload module. Background Technology

[0002] An automatic impeller shaft insertion device is a device that automatically inserts the impeller shaft into the shaft insertion hole of the impeller body.

[0003] In related technologies, the end of the impeller shaft 6 is usually manually pressed into the through hole 71 of the impeller body 7, and then a pressurizing mechanism is used to pressurize the impeller shaft 6 so that the impeller shaft 6 passes through the through hole 71 of the impeller body 7.

[0004] Regarding the aforementioned technologies, the inventors believe that at least the following problems exist: manually pressing the end of the impeller shaft 6 into the through hole 71 of the impeller body 7 is inefficient and needs to be improved. Summary of the Invention

[0005] In order to improve the efficiency of pre-pressing the impeller shaft into the shaft hole of the impeller body, this application provides a pre-pressing module and an automatic impeller shaft insertion device using the pre-pressing module.

[0006] Firstly, the pre-compression module provided in this application adopts the following technical solution:

[0007] A pre-compression module includes an impeller shaft feeding assembly, a material handling assembly, and a pre-compression assembly;

[0008] The impeller shaft feeding assembly includes an alignment plate, an alignment drive mounted on a frame, and a feeding trough. The alignment plate has an alignment hole that communicates with the feeding trough and allows the impeller shaft to pass through. The alignment drive controls whether the alignment hole of the alignment plate is connected to the feeding trough. A stop bar is provided at a position away from the feeding trough from the alignment hole. The alignment plate is connected to a stop drive that drives the stop bar to extend into or out of the alignment hole. The feeding trough is used to store several impeller shafts. A baffle is provided on the outer wall of the feeding trough near the alignment plate. The baffle is used to limit the movement of the impeller shafts in conjunction with the stop bar.

[0009] The material handling assembly includes a material handling robot and a material handling drive mounted on the frame. The material handling drive is used to drive the material handling robot to grip the impeller shaft from the alignment hole and transport the impeller shaft between the pre-compression assembly and the impeller body.

[0010] The pre-compression assembly includes a pre-compression block and a pre-compression drive mounted on the frame. The pre-compression drive is used to drive the pre-compression block to pre-compress the impeller shaft into the through-shaft hole of the impeller body placed on the frame.

[0011] By adopting the above technical solution, when a single impeller shaft enters the alignment hole from the feeding trough, the alignment drive causes the alignment plate to move away from the alignment drive, thus making the alignment hole and the feeding trough disconnected. During the movement of the alignment plate driven by the alignment drive, the stop bar and baffle prevent the impeller shaft from falling out of the alignment hole. The material handling drive causes the material handling robot to move horizontally towards the clamping hole. When the stop bar is withdrawn from the alignment hole by the stop drive, the material handling robot enters the clamping hole to clamp the impeller shaft in the alignment plate. After the material handling robot grips the impeller shaft from the alignment hole, the material handling drive drives the material handling robot to transport the impeller shaft between the pre-compression block and the impeller body. After the pre-compression block, impeller shaft and impeller body are aligned, the pre-compression drive drives the pre-compression block to pre-compress the impeller shaft downward, so that the bottom end of the impeller shaft is pre-inserted into the through-shaft hole of the impeller body. Compared with the related technology, which manually presses the end of the impeller shaft into the through-shaft hole of the impeller body, the pre-compression method of this application is more efficient.

[0012] Optionally, the end of the feeding trough away from the alignment plate is inclined upwards, and the feeding trough is provided with a vibrating drive for vibrating the feeding trough.

[0013] By adopting the above technical solution, several impeller shafts are placed vertically in the feeding trough. The feeding trough is vibrated by the material vibration drive, so that the several impeller shafts can move continuously along the length of the feeding trough.

[0014] Optionally, a leveling rod is provided above the feeding trough, and the feeding trough is also provided with a leveling drive for driving the leveling rod to level several impeller shafts in the feeding trough.

[0015] By adopting the above technical solution, during the process of several impeller shafts moving sequentially along the length of the feeding trough, the leveling drive drives the leveling rod to level the several impeller shafts downwards, thereby making it difficult for the bushings fitted on adjacent impeller shafts to get stuck.

[0016] Optionally, the two opposing inner sidewalls of the picking robot are provided with picking grooves that match the outer sidewall of the impeller shaft.

[0017] By adopting the above technical solution, during the process of the material handling robot gripping the impeller shaft, the material handling groove can facilitate the material handling robot to clamp the impeller shaft and also prevent the sealing ring sleeved on the impeller shaft from falling off.

[0018] Secondly, this application provides an automatic impeller shaft insertion device using a pre-compression module, which adopts the following technical solution:

[0019] An automatic impeller shaft insertion device using a pre-compression module includes a frame and a turntable rotatably connected to the frame;

[0020] The frame is provided with a rotary drive for driving the turntable to rotate. The turntable is provided with a plurality of mounting seats. The mounting seats are provided with mounting holes that can fit into the end wall of the impeller body. The mounting seats are also provided with clearance holes for the impeller shaft to be inserted.

[0021] The outer periphery of the turntable is sequentially provided with an impeller body feeding module, a pressurizing module, and a discharging module.

[0022] By adopting the above technical solution, several impeller bodies are first stored in the impeller body feeding module. The rotary drive is started, and as the rotary drive drives the turntable to rotate continuously, the impeller body feeding module transfers the impeller bodies to the mounting base. When the impeller body rotates with the turntable to the pre-pressing module, the pre-pressing module pre-presses the bottom end of the impeller shaft into the through-shaft hole of the impeller body. When the impeller body with the pre-installed impeller shaft rotates with the turntable to the pressurizing module, the pressurizing module pressurizes the impeller shaft so that the impeller shaft passes through the through-shaft hole of the impeller body. When the impeller body with the impeller shaft passes through rotates with the turntable to the unloading module, the unloading module removes the impeller body with the impeller shaft through the mounting base, thus completing the unloading work.

[0023] Optionally, the impeller body feeding module includes a transfer component, a discharge component, a storage tank, and a conveying track that communicates with the storage tank.

[0024] A conveyor belt is provided at the bottom of the conveying track, and a conveying port is opened at the end of the conveying track away from the storage tank.

[0025] The transfer assembly includes a transfer seat located at the transfer port and a transfer drive for driving the transfer seat closer to or away from the mounting base. The transfer seat is connected to a blocking plate for blocking the impeller body at the transfer port.

[0026] The unloading assembly includes an unloading robot and an unloading drive mounted on the frame. The unloading drive is used to drive the unloading robot to place the impeller body on the transfer seat onto the mounting base.

[0027] By adopting the above technical solution, when the conveyor port is connected to the transfer seat, the conveyor belt transfers the impeller body near the conveyor port to the transfer seat. Then, the transfer drive drives the transfer seat carrying the impeller body to move horizontally towards the mounting seat. During the process of the transfer drive driving the transfer seat towards the mounting seat, the blocking plate can block the impeller body at the conveyor port, thereby preventing the impeller body from falling off the conveyor port. When the transfer seat transfers the impeller body to a position close to the mounting seat, the unloading drive drives the unloading longitudinally, and then the unloading robot places the impeller body on the transfer seat onto the mounting seat.

[0028] Optionally, the end of the storage tank away from the conveying track is inclined upwards, a balance bar is provided on the bottom wall of the storage tank, a tapping rod is connected to the end of the balance bar away from the storage tank, one end of the tapping rod is attached to the bottom wall of the storage tank, the end of the tapping rod away from the storage tank is inclined downwards, a return spring is connected between the end of the tapping rod away from the storage tank and the storage tank, and a pressing block for pressing the tapping rod is provided on the side wall of the rotating disk.

[0029] By adopting the above technical solution, when the pressing block rotates with the turntable to a position close to the striking rod, the pressing block presses the end of the striking rod connected to the return spring towards the bottom wall of the storage tank, thereby compressing the return spring and causing the end of the striking rod that is in contact with the storage tank to move away from the bottom wall of the storage tank. When the pressing block rotates with the turntable to a position away from the striking rod, the return spring rebounds, causing the end of the striking rod away from the return spring to strike the bottom wall of the storage tank, causing the storage tank to vibrate. This prevents the impeller body inside the storage tank from accumulating, thus allowing the impeller body inside the storage tank to slide relatively smoothly into the conveyor track.

[0030] Optionally, a guide plate is provided at one end of the storage tank near the conveying track, and there is a gap between the guide plate and the storage tank at the end away from the storage tank, which is only wide enough for a single impeller body to pass through.

[0031] By adopting the above technical solution, when the impeller body in the storage tank enters the conveying track, the gap between the storage tank and the guide plate allows a single impeller body to pass through and enter the conveying track in sequence. At the same time, the guide plate can block other impeller bodies that are not located in the gap between the guide plate and the storage tank, so as to prevent multiple impeller bodies from getting stuck at the connection between the storage tank and the conveying track.

[0032] Optionally, the pressurization module includes a pressurization block and a pressurization drive mounted on the frame. The pressurization drive is used to drive the pressurization block to pressurize the impeller shaft so that the impeller shaft passes through the shaft hole of the impeller body.

[0033] By adopting the above technical solution, after the pre-pressurization module pre-presses the impeller shaft into the through-shaft hole of the impeller body, the impeller body rotates with the turntable to the underside of the pressurization block. The pressurization drive drives the pressurization block to press the impeller shaft downward so that the impeller shaft passes through the through-shaft hole of the impeller body.

[0034] Optionally, the unloading module includes an unloading robot and an unloading drive mounted on the frame. The unloading drive is used to drive the unloading robot to move the impeller body with the impeller shaft installed out of the mounting base.

[0035] By adopting the above technical solution, when the impeller body with the impeller shaft is rotated to the underside of the unloading robot with the turntable, the unloading drive drives the unloading robot to move, and then the unloading robot picks up the impeller body with the impeller shaft and moves it out of the mounting seat, thereby completing the unloading.

[0036] In summary, this application includes at least one of the following beneficial effects:

[0037] 1. A pre-compression block and a pre-compression drive fixed on the frame are adopted. The pre-compression drive drives the pre-compression block to pre-compress the impeller shaft downward, which enables the bottom end of the impeller shaft to be pre-inserted into the through hole of the impeller body.

[0038] 2. A pressurization module is adopted, which can pressurize the impeller shaft so that the impeller shaft passes through the shaft hole of the impeller body. Attached Figure Description

[0058] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0059] The impeller shaft and impeller body assembled in the embodiments of this application refer to Figure 1 As shown, the outer wall of the impeller shaft 6 is fitted with a bushing 61 and a sealing ring 62, and the sealing ring 62 is located below the bushing 61. The impeller body 7 has a through hole 71 along the axial direction for the impeller shaft 6 to pass through. During the assembly process, the impeller shaft 6, which is fitted with the bushing 61 and the sealing ring 62, needs to be inserted into the through hole 71 of the impeller body 7.

[0060] This application discloses a pre-compression module. (Refer to...) Figure 2 The pre-compression module 2 includes an impeller shaft feeding assembly 21, a material handling assembly 22, and a pre-compression assembly 23, all mounted on the frame 1. First, the impeller body 7 is placed horizontally. Then, several impeller shafts 6 are stored in the impeller shaft feeding assembly 21. The impeller shaft feeding assembly 21 moves a single impeller shaft 6 to a position opposite to the material handling assembly 22. Next, the material handling assembly 22 picks up a single impeller shaft 6 from the impeller shaft feeding assembly 21. Then, the material handling assembly 22 conveys the impeller shaft 6 between the pre-compression assembly 23 and the impeller body 7. Finally, the pre-compression assembly 23 pre-presses the end of the impeller shaft 6 into the through-shaft hole 71 of the impeller body 7. Compared to the method of manually pre-pressing the end of the impeller shaft 6 into the through-shaft hole 71 of the impeller body 7 in related technologies, the pre-compression method of this application is more efficient.

[0061] Reference Figure 3 and Figure 4The impeller shaft feeding assembly 21 includes an alignment plate 211 and a feeding trough 213 fixed on the frame 1. The alignment plate 211 is connected to an alignment drive 212 fixed on the frame 1. In this embodiment, the alignment drive 212 is a cylinder. The alignment plate 211 has an alignment hole 2111 that can communicate with the feeding trough 213. The inner wall of the alignment hole 2111 has a clamping hole 2112. Two stop rods 2113 are provided at the position of the alignment hole 2111 away from the feeding trough 213. The two stop rods 2113 are respectively located above and below the alignment plate 211, and both stop rods 2113 are connected to a position drive 2114 fixed on the alignment plate 211. In this embodiment, the position drive 2114 is a cylinder. A baffle 214 is fixedly connected to the outer wall of the feeding trough 213 away from the alignment drive 212. The end of the feeding trough 213 away from the alignment plate 211 is inclined upwards. A vibrating drive 215 is connected to the bottom wall of the feeding trough 213. In this embodiment, the vibrating drive 215 is a vibration motor. Several impeller shafts 6 are placed vertically inside the feeding trough 213. The vibrating drive 215 vibrates the feeding trough 213, allowing the several impeller shafts 6 to move continuously along the length of the feeding trough 213. When a single impeller shaft 6 enters the alignment hole 2111 from the feed trough 213, the alignment drive 212 drives the alignment plate 211 to move away from the alignment drive 212, so that the alignment hole 2111 and the feed trough 213 are not in communication. During the process of the alignment drive 212 driving the alignment plate 211 to move, the stop bar 2113 and the baffle 214 can prevent the impeller shaft 6 from falling out of the alignment hole 2111.

[0062] Reference Figure 4 A leveling rod 216 is provided above the feeding trough 213. The leveling rod 216 is connected to a leveling drive 217 fixed on the frame 1. In this embodiment, the leveling drive 217 is a cylinder. As the impeller shafts 6 move sequentially along the length of the feeding trough 213, the leveling drive 217 drives the leveling rod 216 to level the impeller shafts 6 downwards, thereby making it less likely for the bushings 61 fitted on adjacent impeller shafts 6 to get stuck.

[0063] Reference Figure 5 and Figure 6The material handling assembly 22 includes a material handling robot 221. In this embodiment, the material handling robot 221 is a gripper cylinder. Two opposing inner sidewalls of the material handling robot 221 have material handling grooves 2211 that match the outer sidewall of the bottom of the impeller shaft 6. The material handling robot 221 is connected to a material handling drive 222 fixed to the frame 1. In this embodiment, the material handling drive 222 is a cylinder. The material handling drive 222 drives the material handling robot 221 to move horizontally towards the clamping hole 2112. When the stop drive 2114 drives the stop lever 2113 to withdraw from the alignment hole 2111, the material handling robot 221 enters the clamping hole 2112 to clamp the impeller shaft 6 in the alignment plate 211. During the process of the material handling robot 221 gripping the impeller shaft 6, the material handling groove 2211 facilitates the material handling robot 221 clamping the impeller shaft 6 and also prevents the sealing ring 62 fitted on the impeller shaft 6 from falling off. After the material handling robot 221 grips the impeller shaft 6 from the alignment hole 2111, the material handling drive 222 drives the material handling robot 221 to transport the impeller shaft 6 between the pre-compression component 23 and the impeller body 7.

[0064] Reference Figure 6 The pre-compression assembly 23 includes a pre-compression block 231, which is coaxial with the impeller body 7. The pre-compression block 231 is connected to a pre-compression drive 232 fixed on the frame 1. In this embodiment, the pre-compression drive 232 is a cylinder. When the material handling drive 222 drives the material handling robot 221 to transport the impeller shaft 6 between the pre-compression block 231 and the impeller body 7, and after the pre-compression block 231, the impeller shaft 6 and the impeller body 7 are coaxial, the pre-compression drive 232 drives the pre-compression block 231 to pre-compress the impeller shaft 6 downward, so that the bottom end of the impeller shaft 6 is pre-inserted into the through hole 71 of the impeller body 7.

[0065] The implementation principle of a pre-compression module in this application embodiment is as follows: the material handling drive 222 drives the material handling robot 221 to move horizontally towards the clamping hole 2112. After the material handling robot 221 enters the clamping hole 2112, it clamps the impeller shaft 6 in the alignment hole 2111. During the process of the material handling robot 221 clamping the impeller shaft 6, the material handling groove 2211 facilitates the material handling robot 221 to clamp the impeller shaft 6 and also prevents the sealing ring 62 sleeved on the impeller shaft 6 from falling off. After the material handling robot 221 clamps the impeller shaft 6 from the alignment hole 2111, the material handling drive 222 drives the material handling robot 221 to transport the impeller shaft 6 between the pre-compression component 23 and the impeller body 7. When the material handling drive 222 drives the material handling robot 221 to transport the impeller shaft 6 between the pre-compression block 231 and the impeller body 7, and after the pre-compression block 231, the impeller shaft 6 and the impeller body 7 are coaxial, the pre-compression drive 232 drives the pre-compression block 231 to pre-compress the impeller shaft 6 downward, so that the bottom end of the impeller shaft 6 is pre-inserted into the shaft hole 71 of the impeller body 7. Compared with the method of manually pressing the end of the impeller shaft 6 into the shaft hole 71 of the impeller body 7 in the related technology, the pre-compression method of this application is more efficient.

[0066] This application also discloses an automatic impeller shaft threading device using a pre-compression module. (See also...) Figure 7 The automatic impeller shaft-passing device using the pre-compression module 2 includes a frame 1, a turntable 12 rotatably connected to the frame 1, and a rotary drive 13 fixed on the frame 1 connected to the turntable 12. In this embodiment, the rotary drive 13 is a rotary motor. A plurality of mounting seats 121 are fixedly connected to the top wall of the turntable 12, and the plurality of mounting seats 121 are evenly distributed around the axis of the turntable 12.

[0067] Reference Figure 7 The impeller body feeding module 3, pressurizing module 4 and unloading module 5 are arranged sequentially around the outer periphery of the turntable 12. First, several impeller bodies 7 are placed in the impeller body feeding module 3. Then, the rotary drive 13 is started. During the continuous rotation of the turntable 12 driven by the rotary drive 13, the impeller body feeding module 3 transfers the impeller bodies 7 to the mounting base 121. When the impeller body 7 rotates with the turntable 12 to the pre-pressing module 2, the pre-pressing module 2 pre-presses the bottom end of the impeller shaft 6 into the through-shaft hole 71 of the impeller body 7. When the impeller body 7 with the impeller shaft 6 pre-installed rotates with the turntable 12 to the pressurizing module 4, the pressurizing module 4 pressurizes the impeller shaft 6 so that the impeller shaft 6 passes through the through-shaft hole 71 of the impeller body 7. When the impeller body 7 with the impeller shaft 6 passes through rotates with the turntable 12 to the unloading module 5, the unloading module 5 removes the impeller body 7 with the impeller shaft 6 through the mounting base 121, thus completing the unloading operation.

[0068] Reference Figure 8The mounting base 121 has a coaxial mounting hole 1211 and a clearance hole 1212. The mounting hole 1211 fits into the end wall of the impeller body 7, thereby preventing the impeller body 7 from shifting or slipping off the mounting base 121. The pressurizing module 4 pressurizes the impeller shaft 6 so that when the impeller shaft 6 passes through the shaft hole 71 of the impeller body 7, the bottom end of the impeller shaft 6 extending out of the shaft hole 71 of the impeller body 7 can be inserted into the clearance hole 1212, thereby avoiding direct contact between the bottom end of the impeller shaft 6 and the top wall of the mounting base 121, making the bottom end of the impeller shaft 6 less likely to be crushed.

[0069] Reference Figure 9 The impeller body feeding module 3 includes a storage tank 33, which is connected to a conveying track 34. A guide plate 334 is fixedly connected to the inner wall of the storage tank 33 near the conveying track 34. A gap is formed between the end of the guide plate 334 away from the connection with the storage tank 33 and the storage tank 33, allowing only a single impeller body 7 to pass through. When the impeller body 7 in the storage tank 33 enters the conveying track 34, the gap between the storage tank 33 and the guide plate 334 facilitates the passage of a single impeller body 7 and its sequential entry into the conveying track 34. At the same time, the guide plate 334 can block other impeller bodies 7 that are not located in the gap between the guide plate 334 and the storage tank 33, so as to prevent multiple impeller bodies 7 from getting stuck at the connection between the storage tank 33 and the conveying track 34.

[0070] Reference Figure 9 and Figure 10 The storage tank 33 is inclined upwards at the end away from the conveyor track 34. A balance bar 331 is provided on the bottom wall of the storage tank 33. A tapping bar 332 is connected to the end of the balance bar 331 away from the storage tank 33. One end of the tapping bar 332 is in contact with the outer wall of the storage tank 33, and a return spring 333 is connected between the end of the tapping bar 332 away from the storage tank 33 and the storage tank 33. A pressing block 122 is fixedly connected to the side wall of the turntable 12. When the pressing block 122 rotates with the turntable 12 to a position close to the tapping bar 332, the pressing block 122 presses the end of the tapping bar 332 connected to the return spring 333 towards the bottom wall of the storage tank 33, thereby compressing the return spring 333 and causing the end of the tapping bar 332 in contact with the storage tank 33 to move away from the bottom wall of the storage tank 33. When the pressing block 122 rotates with the turntable 12 to a position away from the striking bar 332, the return spring 333 rebounds, causing the end of the striking bar 332 away from the return spring 333 to strike the bottom wall of the storage tank 33, causing the storage tank 33 to vibrate. This prevents the impeller body 7 inside the storage tank 33 from accumulating, and allows the impeller body 7 inside the storage tank 33 to slide relatively smoothly into the conveying track 34.

[0071] Reference Figure 9A conveyor belt 341 is provided at the bottom of the conveyor track 34. A conveyor port 342 is opened at the end of the conveyor track 34 away from the storage tank 33. The transfer assembly 31 includes a transfer seat 311 with a transfer port 3111. The transfer seat 311 is connected to a transfer drive 312 fixed on the frame 1. In this embodiment, the transfer drive 312 is a cylinder. A blocking plate 313 is fixedly connected to the side wall of the transfer seat 311 near the transfer drive 312. When the conveyor port 342 is connected to the transfer port 3111, the conveyor belt 341 transfers the impeller body 7 near the conveyor port 342 to the transfer seat 311. Then, the transfer drive 312 drives the transfer seat 311 carrying the impeller body 7 to move horizontally towards the mounting base 121. During the process of the transfer drive 312 driving the transfer seat 311 towards the mounting base 121, the blocking plate 313 can block the impeller body 7 at the conveyor port 342, thereby preventing the impeller body 7 from falling from the conveyor port 342.

The feeding robot 321 is connected to a feeding drive 322 fixed on the frame 1. The feeding drive 322 includes a feeding lateral drive 3221 and a feeding longitudinal drive 3222. In this embodiment, both the feeding lateral drive 3221 and the feeding longitudinal drive 3222 are cylinders. When the transfer seat 311 transfers the impeller body 7 to a position close to the mounting seat 121, the lateral discharge drive 3221 drives the longitudinal discharge drive 3222 and the discharge robot 321 to move horizontally towards the transfer seat 311. Then, the longitudinal discharge drive 3222 drives the discharge robot 321 to move longitudinally towards the transfer seat 311. After the discharge robot 321 picks up the impeller body 7 from the transfer seat 311, the lateral discharge drive 3221 drives the longitudinal discharge drive 3222 and the discharge robot 321 to move horizontally towards the mounting seat 121. Then, the discharge robot 321 places the impeller body 7 on the mounting seat 121. Finally, the discharge drive 322 and the discharge robot 321 return to their initial state.

The pressurization block 41 is connected to a pressurization drive 42 fixed on the frame 1. When the pre-pressurization module 2 pre-presses the impeller shaft 6 into the through-shaft hole 71 of the impeller body 7, the impeller body 7 rotates with the turntable 12 to directly below the pressurization block 41. The pressurization drive 42 drives the pressurization block 41 to press the impeller shaft 6 downward, so that the impeller shaft 6 passes through the through-shaft hole 71 of the impeller body 7.

[0074] Reference Figure 12The unloading module 5 includes an unloading robot 51. In this embodiment, the unloading robot 51 is a gripper cylinder. The unloading robot 51 is connected to an unloading drive 52 fixed on the frame 1. The unloading drive 52 includes a horizontal unloading drive 521 and a vertical unloading drive 522. In this embodiment, both the horizontal unloading drive 521 and the vertical unloading drive 522 are cylinders. When the impeller body 7, through which the impeller shaft 6 passes, rotates with the turntable 12 to below the unloading robot 51, the horizontal unloading drive 521 drives the vertical unloading drive 522 and the unloading robot 51 to move horizontally to... Above the mounting base 121, the unloading longitudinal drive 522 drives the unloading robot 51 to move vertically downward. The unloading robot 51 grips the impeller body 7 through which the impeller shaft 6 is inserted. Then, the unloading longitudinal drive 522 drives the unloading robot 51 to move vertically upward. Next, the unloading transverse drive 521 drives the unloading longitudinal drive 522 and the unloading robot 51 to move away from the frame 1. Finally, the unloading robot 51 releases the impeller body 7 through which the impeller shaft 6 is inserted, thus completing the unloading. After the unloading is completed, the unloading drive 52 and the unloading robot 51 return to their initial state.

[0075] The implementation principle of an automatic impeller shaft-passing device using a pre-compression module in this application embodiment is as follows: First, several impeller bodies 7 are stored in the impeller body feeding module 3. The rotary drive 13 is started. During the continuous rotation of the turntable 12 driven by the rotary drive 13, the impeller body feeding module 3 transfers the impeller bodies 7 to the mounting base 121. When the impeller body 7 rotates with the turntable 12 to the pre-compression module 2, the pre-compression module 2 pre-compresses the bottom end of the impeller shaft 6 into the shaft-passing hole 71 of the impeller body 7. When the impeller body 7 with the pre-installed impeller shaft 6 rotates with the turntable 12 to the pressure module 4, the pressure module 4 pressurizes the impeller shaft 6 so that the impeller shaft 6 passes through the shaft-passing hole 71 of the impeller body 7. When the impeller body 7 with the impeller shaft 6 passes through rotates with the turntable 12 to the unloading module 5, the unloading module 5 removes the impeller body 7 with the impeller shaft 6 through the mounting base 121, thus completing the unloading work.
