Description

Technical Field

[0001] This invention relates to the field of water suction fan processing equipment technology, specifically to an integrated automated assembly device for water suction fan parts. Background Technology

[0002] When assembling a water suction fan, the press-fitting of the impeller hub and the main shaft is one of the core assembly processes. This involves pressing the impeller hub and the drive shaft together using an interference fit. The assembly structure of the impeller hub and main shaft primarily serves the core function of power transmission. During operation, the rotational torque output by the main shaft is transmitted completely and stably to the impeller hub through the tightly fitted assembly surfaces, driving the impeller to rotate synchronously at high speed. This ensures the water suction fan performs its basic functions of air intake and exhaust. Secondly, the press-fitted overall structure can withstand the centrifugal force generated by the impeller during operation, the axial airflow thrust, and the alternating loads caused by equipment start-up, shutdown, and fluctuations in operating conditions. It evenly distributes various forces, reduces localized stress concentration, improves the overall structural strength and operational rigidity of rotating components, and effectively prevents impeller loosening, swaying, and vibration.

[0003] However, the existing impeller hub and main shaft pressing assembly of water suction fans mostly rely on manual positioning of the impeller hub onto the main shaft assembly before pressing. This semi-automatic pressing method greatly reduces the speed and automation level of the equipment in pressing the impeller hub and main shaft. At the same time, it also lacks stability and efficiency in the material feeding, pressing positioning, and alignment of the impeller hub and main shaft, thus reducing the speed of the equipment in the integrated pressing of the impeller hub and main shaft. Therefore, an integrated automated assembly device for water suction fan parts is needed to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated automated assembly device for water suction fan accessories to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated automated assembly device for water suction fan accessories, comprising a cam divider, a guide turntable fixedly disposed at the upper output end of the cam divider, a support base fixedly disposed at the upper part of the cam divider, and a support top plate fixedly disposed at the upper part of the support base.

[0006] The alignment assembly consists of four sets, all of which are fixedly mounted at equal intervals on the upper part of the guide turntable via support brackets. The alignment assembly is used to limit and align the impeller hub and the main shaft assembly of the water suction fan.

[0007] Impeller feeding assembly is fixedly installed inside the support top plate and is directly opposite the initial feeding station on the upper part of the guide turntable. The impeller feeding assembly is used to feed the impeller hubs one by one into the alignment assembly.

[0008] The material guiding assembly, the side output end of the cam divider drives the synchronous pulley to rotate through the drive shaft, and the synchronous pulley is meshed with the material guiding assembly through the synchronous belt. The material guiding assembly is used to synchronously press the impeller hub and the water suction fan main shaft assembly inside the alignment assembly.

[0009] An industrial camera is fixedly installed at the inspection station located on the upper part of the feed turntable by a camera bracket, and a supplementary light ring for supplementary lighting is installed at the bottom of the industrial camera. The industrial camera is used to take pictures and inspect the pressed impeller hub and the water suction fan main shaft assembly.

[0010] The unloading assembly is fixedly installed at the unloading station on the upper part of the guide turntable. The unloading assembly is used to clamp and unload the press-fitted impeller hub and water suction fan main shaft assembly, and the unloading assembly is also used to load a new set of water suction fan main shaft assemblies.

[0011] The upper part of the cam divider drives the alignment component to intermittently circulate and guide the impeller hub and the main shaft assembly of the water suction fan through the guide turntable. The side output end of the cam divider drives the guide component to synchronously press the impeller hub and the main shaft assembly of the water suction fan to the pressing station through the drive shaft, synchronous pulley one and synchronous belt one.

[0012] Specifically, the material guiding assembly includes an alignment guide seat and a support guide seat disposed on the side of the alignment guide seat. The lower inner side of the alignment guide seat is connected to the threaded slide seat by an adjusting bolt, thereby driving the idler wheel to move laterally inside the alignment guide seat. A second synchronous pulley is rotatably engaged with the upper outer side of the alignment guide seat via a bearing seat. A cam is fixedly disposed at the power output end of the second synchronous pulley. The output end of the second synchronous pulley drives the pressing assembly to move up and down cyclically inside the support guide seat via the cam. The pressing assembly is used to press and hold the impeller hub and the main shaft assembly of the water suction fan. A cam groove is opened inside the cam, and two sets of T-shaped blocks are disposed at the bottom of the support guide seat to rigidly limit the pressing assembly.

[0013] Specifically, synchronous pulley one is rotatably engaged with the bottom of the support base via a transmission guide seat. The interior of the alignment guide seat is adapted to the threaded slide via adjusting bolts, thereby driving the idler wheel to elastically fit against the side of synchronous belt one. The idler wheel adjusts the tension of synchronous belt one as needed, improving the stability of the meshing transmission between synchronous pulley one and synchronous pulley two.

[0014] Specifically, the pressing assembly includes a pressing guide seat and a cam slide shaft fixedly disposed on the side of the pressing guide seat. Inside the pressing guide seat, a positioning slide seat is elastically slidably engaged by three sets of buffer springs arranged in parallel. A pressing fixture is fixedly disposed at the bottom of the positioning slide seat. Limiting guide plates are fixedly disposed on both sides of the pressing fixture.

[0015] Specifically, the second synchronous pulley is adapted to the cam slide shaft through the cam groove, thereby driving the pressing guide to move up and down. The pressing guide, through the buffer spring and the positioning slide, drives the pressing fixture to press and hold the impeller hub and the main shaft assembly of the water suction fan. The pressing fixture is slidably engaged with the T-shaped block through the limiting guide plate. The T-shaped block can rigidly limit the limiting guide plate to prevent the subsequent pressing guide from driving the pressing fixture to press the impeller hub and the main shaft assembly of the water suction fan to the limit, thereby improving the protection performance of the impeller hub and the main shaft assembly of the water suction fan.

[0016] Specifically, the impeller feeding assembly includes a feeding bin for support, a positioning bracket integrally formed and fixedly installed on the upper part of the feeding bin, a closed cover plate slidably inserted into the positioning bracket, and a positioning sliding shaft fixedly installed at the center of the lower end face of the closed cover plate. The impeller hub is equidistantly slidably engaged with the inside of the feeding bin through the positioning sliding shaft. Stepper motors are fixedly installed on the bottom of both sides of the feeding bin through transmission brackets, and two sets of opposing baffles are fixedly engaged at the power output end of the stepper motors. A proximity switch is fixedly installed at the front of the feeding bin, directly opposite the bottom impeller hub, and a handle is located at the center of the upper end face of the closed cover plate.

[0017] Specifically, multiple impeller hubs are equidistantly slidably engaged inside the feeding hopper via positioning slide shafts. Two sets of stepper motors guide the impeller hubs one by one through two sets of opposing baffles. The distance between the two sets of opposing baffles is equal to the thickness of the impeller hubs. When guiding the impeller hubs one by one, the two sets of baffles can limit the impeller hubs one by one, so that the impeller hubs can be fed one by one into the feeding hopper to the upper part of the water suction fan main shaft assembly. At the same time, the feeding hopper and positioning slide shafts can fit against the upper part of the water suction fan main shaft assembly and the upper main shaft of the water suction fan main shaft assembly, which facilitates the positioning of the impeller hubs.

[0018] Specifically, the unloading assembly includes a cylinder seat, a thin cylinder fixedly mounted on the upper part of the cylinder seat, and a support slide fixedly mounted on the power output end of the thin cylinder. A gear and rack type swing cylinder is fixedly mounted at the center of the lower end face of the support slide. The gear and rack type swing cylinder drives two sets of wide grippers to swing 180 degrees in an alternating manner through a locking plate. The two clamping ends of each set of wide grippers are fixedly mounted with unloading fixtures through clamping side plates. A proximity switch 2 for position detection is set at the inner fitting part of the unloading fixture.

[0019] Specifically, the thin-type cylinder drives two sets of wide-type air grippers to move up and down through the support slide, and the gear and rack type swing cylinder drives the wide-type air grippers to alternately load and unload the impeller hub and the main shaft assembly of the water suction fan through the locking plate. The wide-type air grippers drive two sets of unloading clamps to limit and clamp the side of the main shaft assembly of the water suction fan through the clamping side plate. The second proximity switch is used to detect the position of the side of the main shaft assembly of the water suction fan. The second proximity switch can detect the position of the workpiece to be loaded and unloaded, thereby improving the stability of the unloading and clamping of the impeller hub and the main shaft assembly of the water suction fan.

[0020] Specifically, the alignment component includes a water-absorbing fan housing fixture, an integrally formed positioning base fixedly installed at the bottom of the water-absorbing fan housing fixture, and six sets of positioning insert shafts equidistantly fixedly installed on the upper part of the water-absorbing fan housing fixture. A servo motor is fixedly installed on the upper part of the positioning base through a motor seat, and the power output end of the servo motor drives the synchronous pulley four to rotate inside the positioning base through synchronous pulley three and synchronous belt two. A threaded rotating sleeve is fixedly engaged inside the synchronous pulley four, and the synchronous pulley four drives the unloading push plate to move up and down inside the positioning base through the threaded rotating sleeve and the thread of the lead screw. A proximity switch three is fixedly installed inside the unloading push plate.

[0021] Specifically, the upper part of the suction fan housing fixture uses six sets of annularly distributed positioning pins to radially slide and limit the suction fan main shaft assembly. The servo motor drives the threaded swivel to rotate through synchronous pulley three, synchronous belt two, and synchronous pulley four. The threaded swivel drives the unloading push plate through the lead screw to unload and lift the press-fitted impeller hub and suction fan main shaft assembly along the axial direction of the positioning base. When unloading the impeller hub and suction fan main shaft assembly, the threaded swivel can lift the unloading push plate through the lead screw to push out the suction fan main shaft assembly, which facilitates the clamping and unloading of the subsequent unloading fixture and improves the stability of unloading.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention is a multi-station integrated impeller hub and main shaft assembly equipment. When assembling the impeller hub and the water suction fan main shaft assembly in an integrated manner, the cam divider can sequentially position the water suction fan main shaft assembly to the bottom of the impeller feeding assembly, the feeding assembly, the industrial camera, and the unloading assembly through the guide turntable and the alignment component. This allows the impeller feeding assembly, the feeding assembly, the industrial camera, and the unloading assembly to cooperate with the cam divider in guiding the material, thereby performing integrated feeding, pressing, inspection, and unloading operations on the impeller hub and the water suction fan main shaft assembly. This effectively improves the efficiency and automation of the equipment in the integrated pressing of the impeller hub and the water suction fan main shaft assembly, thereby increasing the speed of batch pressing of the impeller hub and the water suction fan main shaft assembly.

[0024] 2. This invention is a follow-up impeller hub and water suction fan main shaft assembly press-fitting equipment. During the press-fitting of the impeller hub and water suction fan main shaft assembly, the upper part of the cam divider can drive the alignment component through the material guide turntable to intermittently guide the impeller hub and water suction fan main shaft assembly. Simultaneously, the side of the cam divider can drive the synchronous pulley and cam to rotate synchronously through the drive shaft, synchronous pulley one, and synchronous belt one. This allows the cam to be limited by the sliding of the cam groove and cam slide shaft. Simultaneously, the material guide turntable synchronously and intermittently guides the impeller hub and water suction fan main shaft assembly, thus enabling uninterrupted synchronous pressure holding and press-fitting of the impeller hub and water suction fan main shaft assembly through the press-fitting fixture. This effectively improves the utilization efficiency of the cam divider's power, reduces bottleneck time, and increases processing efficiency.

[0025] 3. By setting up an impeller feeding assembly, the feeding bin can slide and limit the impeller hub through the positioning slide shaft, thereby aligning the impeller hub with the main shaft inside the water suction fan assembly. This effectively improves the accuracy and stability of the impeller hub positioning and limiting to the main shaft inside the water suction fan assembly. At the same time, the two sets of stepper motors can feed the impeller hub one by one through the baffle plate, which also improves the stability of feeding the impeller hub one by one, thereby improving the stability of the pre-assembly of the impeller hub with the water suction fan assembly.

[0046] The invention will be further described below with reference to the accompanying drawings.

[0047] Example 1

[0048] Please see Figure 1-4 The present invention provides an embodiment of an integrated automated assembly device for water suction fan accessories, comprising a cam divider 10, a guide turntable 8 fixedly disposed on the upper output end of the cam divider 10, a support base 1 fixedly disposed on the upper part of the cam divider 10, and a support top plate 15 fixedly disposed on the upper part of the support base 1.

[0052] The main shaft assembly 7 of the water suction fan consists of the water suction fan power assembly and the housing, which facilitates the subsequent press-fitting of the impeller hub 6;

[0053] Impeller feeding assembly 3 is fixedly installed inside the supporting top plate 15, and the impeller feeding assembly 3 is directly opposite the initial feeding station on the upper part of the guide turntable 8.

[0057] The unloading component 4 is fixedly installed at the unloading station on the upper part of the guide turntable 8. The unloading component 4 is used to clamp and unload the press-fitted impeller hub 6 and the water suction fan main shaft assembly 7. The unloading component 4 is also used to feed a new set of water suction fan main shaft assemblies 7.

[0058] The upper part of the cam divider 10 drives the alignment component 5 to intermittently circulate and guide the impeller hub 6 and the water suction fan main shaft assembly 7 through the guide turntable 8. The side output end of the cam divider 10 drives the guide component 2 to synchronously press the impeller hub 6 and the water suction fan main shaft assembly 7 that are fed to the pressing station through the drive shaft 11, the synchronous pulley 13 and the synchronous belt 14.

[0059] Synchronous pulley 13, synchronous belt 14 and synchronous pulley 2210 all have arc-shaped teeth for meshing synchronous transmission;

[0060] like Figure 5 , Figure 6 and Figure 7 The material guiding assembly 2 includes an alignment guide seat 21 and a support guide seat 29 disposed on the side of the alignment guide seat 21. The lower inner side of the alignment guide seat 21 is connected to the threaded slide seat 27 by adjusting bolts 25, thereby driving the idler wheel 26 to move laterally inside the alignment guide seat 21. The upper outer side of the alignment guide seat 21 is rotatably engaged with a synchronous pulley 2210 by a bearing seat. A cam 23 is fixedly disposed at the power output end of the synchronous pulley 2210. The output end of the synchronous pulley 2210 drives the pressing assembly 22 to move up and down cyclically inside the support guide seat 29 through the cam 23. The pressing assembly 22 is used to press and hold the impeller hub 6 and the water suction fan main shaft assembly 7. A cam groove 24 is opened inside the cam 23. Two sets of T-shaped blocks 28 are disposed at the bottom of the support guide seat 29 for rigidly limiting the pressing assembly 22.

[0061] like Figure 8 The pressing assembly 22 includes a pressing guide 222 and a cam slide 224 fixedly disposed on the side of the pressing guide 222. The pressing guide 222 has a positioning slide 223 elastically slidably engaged inside by three sets of buffer springs 225 arranged in parallel. The pressing guide 222 is provided with four sets of linear bearings. The pressing guide 222 can slide and limit the support guide 29 through the linear bearings, thereby improving the stability of the pressing guide 222 in the vertical displacement inside the support guide 29.

[0062] Furthermore, a pressing fixture 226 is fixedly installed at the bottom of the positioning slide 223. Limiting guide plates 221 are fixedly installed on both sides of the pressing fixture 226. An avoidance groove is opened inside the pressing fixture 226. The avoidance groove can avoid the main shaft when pressing the impeller hub 6 and the water suction fan main shaft assembly 7.

[0063] like Figure 9 , Figure 10 and Figure 11 The impeller feeding assembly 3 includes a feeding bin 38 for support, a positioning bracket 31 integrally formed and fixedly installed on the upper part of the feeding bin 38, a closed cover plate 32 slidably inserted into the positioning bracket 31, and a positioning sliding shaft 33 fixedly installed at the center of the lower end face of the closed cover plate 32. The impeller hub 6 is equidistantly slidably engaged with the feeding bin 38 through the positioning sliding shaft 33. Stepper motors 34 are fixedly installed on the bottom of both sides of the feeding bin 38 through transmission brackets 35. The model of the stepper motor 34 is ZNH02-020-N.

[0064] Two sets of opposing baffles 36 are fixedly connected to the power output end of the stepper motor 34. A proximity switch 37 is fixedly installed at the front of the feeding bin 38, directly opposite the bottom impeller hub 6. A handle 39 is located at the center of the upper end face of the closed cover plate 32.

[0065] The model numbers of proximity switches 1 (37), 2 (47), and 3 (511) are all KF5001. The model number of the external touch screen module used to control electrical and program operation is ECP200-070.

[0066] like Figure 12 and Figure 13 The feeding assembly 4 includes a cylinder seat 41, a thin cylinder 42 fixedly mounted on the upper part of the cylinder seat 41, and a support slide 49 fixedly mounted on the power output end of the thin cylinder 42. The model of the thin cylinder 42 is: WGJ17-40-45-Y-2.

[0067] A rack and pinion type swing cylinder 48 is fixedly installed at the center of the lower end face of the support slide 49, and the rack and pinion type swing cylinder 48 drives two sets of wide-type pneumatic claws 44 to swing 180 degrees alternately through the locking plate 43.

[0068] The model number of the rack and pinion type swing cylinder 48 is: WGP01-20-RM-2 rack and pinion type swing cylinder;

[0069] Each set of wide-type pneumatic grippers 44 has a material unloading fixture 46 fixedly installed at both clamping ends via clamping side plates 45, and a proximity switch 47 for position detection is installed at the inner fitting part of the material unloading fixture 46.

[0070] The model number of the wide-type pneumatic gripper 44 is: WGY11-25-50-2.

[0071] like Figure 14 , Figure 15 and Figure 16The alignment component 5 includes a suction fan housing fixture 51, a positioning base 53 integrally formed and fixedly installed at the bottom of the suction fan housing fixture 51, and six sets of positioning insert shafts 52 equidistantly fixedly installed on the upper part of the suction fan housing fixture 51. A servo motor 54 is fixedly installed on the upper part of the positioning base 53 via a motor mount. The model of the servo motor 54 is MHMF022L1U2M.

[0072] Furthermore, the power output end of the servo motor 54 drives the synchronous pulley 4 57 to rotate inside the positioning base 53 through the synchronous pulley 3 55 and the synchronous belt 2 56. A threaded sleeve 59 is fixedly connected inside the synchronous pulley 4 57, and the synchronous pulley 4 57 drives the unloading push plate 510 to move up and down inside the positioning base 53 through the threaded sleeve 59 and the thread of the lead screw 58. The unloading push plate 510 is also provided with two sets of linear sliding shafts at the bottom. The linear sliding shafts slide and limit the movement with two sets of linear bearings at the bottom of the positioning base 53, which can improve the stability of the unloading push plate 510's up and down movement.

[0073] A proximity switch 511 is fixedly installed inside the feeding push plate 510.

[0074] like Figure 3 and Figure 5 The synchronous pulley 13 is rotatably engaged with the bottom of the support base 1 via the transmission guide 12. The transmission guide 12 has two sets of bearing seats inside, which are used to limit the docking shaft of the synchronous pulley 13.

[0075] The interior of the alignment guide seat 21 is adapted to the threaded slide seat 27 by adjusting the bolt 25, thereby driving the idler wheel 26 to elastically fit the side of the timing belt 14. The idler wheel 26 adjusts the tension of the timing belt 14 as needed, thereby improving the stability of the meshing transmission between the timing pulley 13 and the timing pulley 2210.

[0076] like Figure 6 and Figure 7 The synchronous pulley 2210 is adapted to the cam slide shaft 224 via the cam groove 24, thereby driving the pressing guide 222 to move up and down. The cam groove 24 is divided into a lifting groove and a pressing groove. The lifting groove has a small diameter and the pressing groove has a large diameter. The pressing groove can maintain a limit with the cam slide shaft 224, thereby enabling the pressing fixture 226 to stably press and maintain pressure on the upper part of the impeller hub 6, improving the stability of the pressing between the impeller hub 6 and the main shaft assembly 7 of the water suction fan.

[0077] Furthermore, the pressing guide seat 222 drives the pressing fixture 226 to press and hold the impeller hub 6 and the water suction fan main shaft assembly 7 through the buffer spring 225 and the positioning slide seat 223. The pressing fixture 226 slides and engages with the T-shaped block 28 through the limiting guide plate 221. The T-shaped block 28 can rigidly limit the limiting guide plate 221 to prevent the pressing guide seat 222 from driving the pressing fixture 226 to press the impeller hub 6 and the water suction fan main shaft assembly 7 too much, thereby improving the protection performance of the impeller hub 6 and the water suction fan main shaft assembly 7.

[0078] like Figure 10 Multiple impeller hubs 6 are equidistantly slidably engaged inside the feeding bin 38 via positioning slide shafts 33. The positioning slide shafts 33 are key shafts, which can be adapted to slide with the keyways inside the impeller hubs 6, thereby allowing the impeller hubs 6 to be arranged along the direction of the key shaft. At the same time, the key shaft is aligned with the main shaft key inside the water suction fan main shaft assembly 7, which facilitates subsequent material feeding and alignment.

[0079] like Figure 10 and Figure 11 Two sets of stepper motors 34 guide the impeller hubs 6 one by one through two sets of opposing baffles 36. The distance between the two sets of opposing baffles 36 is equal to the thickness of the impeller hubs 6. When guiding the impeller hubs 6 one by one, the two sets of baffles 36 can limit the impeller hubs 6 one by one, so that the impeller hubs 6 can be discharged one by one into the feeding bin 38 to the upper part of the water suction fan main shaft assembly 7. At the same time, the feeding bin 38 and the positioning slide shaft 33 can fit with the upper part of the water suction fan main shaft assembly 7 and the main shaft of the water suction fan main shaft assembly 7, which facilitates the positioning of the impeller hubs 6.

[0080] like Figure 1 and Figure 13 The thin cylinder 42 drives two sets of wide air claws 44 to move up and down through the support slide 49, and the gear and rack type swing cylinder 48 drives the wide air claws 44 to load and unload the impeller hub 6 and the water suction fan main shaft assembly 7 in an alternating manner through the locking plate 43. The gear and rack type swing cylinder 48 is a gear and rack type swing cylinder that can drive the two sets of wide air claws 44 to swing 180 degrees, which facilitates the loading of the water suction fan main shaft assembly 7 and the unloading of the impeller hub 6 and the water suction fan main shaft assembly 7.

[0081] like Figure 13 The wide-type pneumatic gripper 44 drives two sets of unloading clamps 46 to limit and clamp the side of the water suction fan main shaft assembly 7 through the clamping side plate 45. The proximity switch 47 is used to detect the position of the side of the water suction fan main shaft assembly 7. The proximity switch 47 can detect the position of the workpiece to be loaded and unloaded, thereby improving the stability of the unloading clamping of the impeller hub 6 and the water suction fan main shaft assembly 7.

[0082] like Figure 4 and Figure 15 The upper part of the suction fan housing fixture 51 uses six sets of annularly distributed positioning pins 52 to radially slide and limit the suction fan main shaft assembly 7. When the suction fan main shaft assembly 7 is being loaded and positioned, the flange on the side of the suction fan main shaft assembly 7 can be axially positioned with the positioning pins 52, thereby improving the accuracy of the loading and positioning of the suction fan main shaft assembly 7. At the same time, it can synchronously position the direction of the main shaft key inside the suction fan main shaft assembly 7, which is convenient for subsequent positioning and assembly with the impeller hub 6.

[0083] like Figure 16 Furthermore, the servo motor 54 drives the threaded rotating sleeve 59 to rotate via the synchronous pulley three 55, synchronous belt two 56, and synchronous pulley four 57. The threaded rotating sleeve 59 drives the unloading push plate 510 via the lead screw 58 to unload and lift the press-fitted impeller hub 6 and the water suction fan main shaft assembly 7 along the axial direction of the positioning base 53. The synchronous pulley four 57 and the threaded rotating sleeve 59 are fixedly connected by bolts, and the threaded rotating sleeve 59 is rotatably locked inside the positioning base 53 via the bearing seat. When unloading the impeller hub 6 and the water suction fan main shaft assembly 7, the threaded rotating sleeve 59 can drive the unloading push plate 510 via the lead screw 58 to lift and push out the water suction fan main shaft assembly 7, which facilitates the subsequent clamping and unloading by the unloading fixture 46 and improves the stability of unloading.

[0084] Working principle: Before use, the operator can position the conveyor line of the water suction fan main shaft assembly 7 at the unloading station of the guide turntable 8. Multiple sets of water suction fan main shaft assemblies 7 to be pressed are arranged at equal intervals on the conveyor line. The conveyor line can be used to feed the water suction fan main shaft assembly 7 and to place the pressed impeller hub 6 and water suction fan main shaft assembly 7.

[0085] like Figure 1 and Figure 12When loading the main shaft assembly 7 of the suction fan, the external touch screen module can activate the solenoid valve via an electrical signal. This solenoid valve activates the corresponding thin cylinder 42, which in turn moves the support slide 49 downwards. At this time, the support slide 49 can simultaneously move the two sets of wide grippers 44 downwards via the gear and rack type swing cylinder 48. The external wide grippers 44 can be positioned on the side of the main shaft assembly 7 of the suction fan on the conveyor line, while the internal wide grippers 44 can be positioned on the side of the lifted impeller hub 6 and the main shaft assembly 7 of the suction fan. Subsequently, the proximity switch 47 can sense the workpiece's position and then transmit an electrical signal to the touch screen module. This touch screen module can activate the wide grippers 44 via the solenoid valve, allowing the external wide grippers 44 to move the new set of suction fans via the unloading clamp 46. The fan main shaft assembly 7 is clamped and limited, while the internal wide-type pneumatic gripper 44 can clamp and limit the assembled impeller hub 6 and the water suction fan main shaft assembly 7 through the unloading fixture 46. Then, the thin cylinder 42 is raised, and the gear and rack type swing cylinder 48 reverses 180 degrees after the thin cylinder 42 is raised. At this time, the unloading fixture 46 with the press-fitted impeller hub 6 and water suction fan main shaft assembly 7 is directly opposite the empty station on the conveyor line. At the same time, the two sets of unloading fixtures 46 holding a new set of water suction fan main shaft assemblies 7 are directly opposite the empty water suction fan housing fixture 51 to be loaded. Then, the thin cylinder 42 moves down again. At this time, the water suction fan main shaft assembly 7 held by the two sets of unloading fixtures 46 can be positioned and limited inside the water suction fan housing fixture 51 through the multiple sets of positioning inserts 52 on the upper part of the water suction fan housing fixture 51. Figure 16 Proximity switch 3 511 can detect the position of the feeding water suction fan main shaft assembly 7. The wide-type pneumatic gripper 44 located on the unloading side can release the limit on the impeller hub 6 and the water suction fan main shaft assembly 7 by clamping the side plate 45 and proximity switch 2 47, so that the press-fitted impeller hub 6 and water suction fan main shaft assembly 7 can be unloaded onto the conveyor line and then transported to the next assembly module.

[0086] like Figure 1 and Figure 10When the aforementioned suction fan main shaft assembly 7 completes loading, the cam divider 10 continues to drive the guide turntable 8 to rotate intermittently by 90 degrees according to the normal rhythm. This allows the guide turntable 8 to position the suction fan housing fixture 51 and the loaded suction fan main shaft assembly 7 to the loading station of the impeller hub 6, i.e., the impeller loading assembly 3. A photoelectric switch is installed at the loading station of the impeller hub 6 to detect the position of the suction fan housing fixture 51. When the photoelectric switch detects that the suction fan housing fixture 51 is in place, it can transmit an electrical signal to the external touch screen module. The touch screen module can then start two sets of stepper motors 34 via the PLC. At this time, the two sets of stepper motors 34 can drive the two sets of bottom baffles 36 to rotate 180 degrees. The bottom baffles 36 rotate to the outside to release the bottom impeller hub. The limit of 6, and the baffle plate 36 located at the top can limit the second to last impeller hub 6. Then the impeller hub 6 can move axially linearly along the positioning slide shaft 33. Since the positioning slide shaft 33 is almost in contact with the main shaft inside the water suction fan main shaft assembly 7, and the distance between the discharge bin 38 and the upper part of the water suction fan main shaft assembly 7 is also small, the positioning slide shaft 33 can guide the impeller hub 6 to the upper part of the water suction fan main shaft assembly 7 by aligning with the main shaft inside the water suction fan main shaft assembly 7. Then the impeller hub 6 falls to the upper part of the water suction fan main shaft assembly 7 under the action of gravity along the main shaft inside the water suction fan main shaft assembly 7, completing the feeding operation of the impeller hub 6. At the same time, the proximity switch 37 can detect the position and empty material of the impeller hub 6 inside the discharge bin 38, which is convenient for subsequent reminders of feeding and replenishment.

[0087] like Figure 1 , Figure 2 , Figure 5 and Figure 6 After the impeller hub 6 is loaded, the cam divider 10 continues to drive the guide turntable 8 to rotate intermittently by 90 degrees according to the normal rhythm. When the roller inside the cam divider 10 is driven to rotate by the cam, such as Figure 2 The output end of the cam divider 10 can synchronously drive the synchronous pulley 13 to rotate via the drive shaft 11, so that the synchronous pulley 13 can synchronously drive the synchronous pulley 2210 to rotate via the synchronous belt 14. At this time, if Figure 6 and Figure 7The synchronous pulley 2210 can synchronously drive the cam slide shaft 224 and the pressing guide seat 222 to move up and down along the inside of the support guide seat 29 through the cam 23 and cam groove 24. When the cam inside the cam divider 10 drives the roller to rotate, that is, when the cam divider 10 drives the guide turntable 8 to rotate, the cam groove 24 can drive the pressing guide seat 222 and the pressing fixture 226 to lift through the cam slide shaft 224, releasing the pressing limit on the impeller hub 6. At the same time, when the cam and roller inside the cam divider 10 are in a self-locking state, the cam groove 24 can drive the cam slide shaft 224 to move down, so that the cam slide shaft 224 can move up and down through the fixed... The sliding block 223 drives the pressing fixture 226 to press against the upper part of the impeller hub 6, thereby pressing the impeller hub 6 to the lowest part of the main shaft of the suction fan assembly 7, completing the pressing operation. Simultaneously, the buffer spring 225 provides sufficient elasticity for the downward movement of the pressing guide 222, improving the protection of the pressing fixture 226 for the impeller hub 6 and the suction fan main shaft assembly 7 during pressing. Meanwhile, the large-diameter portion of the cam groove 24 continuously limits the movement with the cam slide 224, providing pressure holding time for the pressing of the impeller hub 6 and the suction fan main shaft assembly 7. At the same time, the T-shaped locking block 28 rigidly limits the limiting guide plate 221, preventing the pressing fixture 226 from pressing beyond its limit, thus improving protection.

[0088] like Figure 3 and Figure 10 After the impeller hub 6 and the suction fan main shaft assembly 7 are pressed into place, the cam divider 10 continues to drive the guide turntable 8 to rotate intermittently by 90 degrees according to the normal rhythm. At this time, the industrial camera 17 can take pictures of the impeller hub 6 and the suction fan main shaft assembly 7 for inspection, which facilitates the subsequent rejection of impeller hubs 6 and suction fan main shaft assemblies 7 that are not pressed into place. When the cam divider 10 drives the guide turntable 8 to rotate to the unloading station, at this time... Figure 15 The servo motor 54 can drive the synchronous pulley 4 57 to rotate through the synchronous pulley 3 55 and the synchronous belt 2 56. At the same time, the synchronous pulley 4 57 can be threadedly connected to the lead screw 58 through the threaded sleeve 59, thereby driving the unloading push plate 510 to rise. The unloading push plate 510 can lift the pressed impeller hub 6 and the water suction fan main shaft assembly 7 along the positioning insert shaft 52 until they are positioned between the two sets of unloading fixtures 46. Then, the proximity switch 2 47 completes the unloading detection, and then unloads the impeller hub 6 and the water suction fan main shaft assembly 7 through the unloading fixture 46. At the same time, the proximity switch 3 511 performs empty material detection and starts the servo motor 54 to drive the unloading push plate 510 to reset.
