Description

Technical Field

[0001] The present application relates to the technical field of cross-flow fans, and particularly to a riveting shaft device for a cross-flow fan middle plate. Background Art

[0002] A cross-flow fan is a special fan design, which is widely used in equipment such as air conditioners, fan systems, and air curtains. The cross-flow fan is usually multi-bladed and long cylindrical, with forward multi-wing blades. When air flows through the fan, it is forced to pass through the blades and generates a high-speed rotating air flow around the blades. The air flow enters the blade grid from the open part of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other blade grid, forming a working air flow.

[0003] However, in the production and assembly process of cross-flow fans, especially in the riveting link of the middle plate, the shaft rod is usually inserted into the shaft hole of the aluminum seat. The outer wall of the aluminum seat is in a stepped ring shape. The aluminum seat is inserted into the shaft hole of the middle plate, and the middle plate is stuck at the middle position of the aluminum seat. One side of the middle plate abuts against one end side of the large ring of the aluminum seat. During manual operation, it is difficult to align the axes of the shaft rod, the aluminum seat, and the middle plate, resulting in low assembly efficiency of the middle plate. Summary of the Invention

[0004] In order to improve the assembly efficiency of the middle plate, the present application provides a riveting shaft device for a cross-flow fan middle plate.

[0005] A riveting shaft device for a cross-flow fan middle plate provided by the present application adopts the following technical solutions: A riveting shaft device for a cross-flow fan middle plate includes: A workbench, on the top of which a turntable is rotatably connected. A plurality of riveting shaft platforms are arranged on the top of the turntable. The riveting shaft platforms are circumferentially distributed equidistantly along the turntable. A fixed shaft hole is arranged on the top of the riveting shaft platform. The periphery of the turntable is successively surrounded by: A fixed shaft mechanism for inserting a shaft rod into the fixed shaft hole; A fixed seat mechanism for placing the aluminum seat on the riveting shaft platform and making the axis of the aluminum seat collinear with the axis of the shaft rod; A fixed plate mechanism for placing the middle plate on the riveting shaft platform and making the axis of the middle plate collinear with the axis of the shaft rod; A riveting mechanism for riveting the shaft rod, the aluminum seat, and the middle plate after their axes are collinear; A material taking mechanism for taking out the riveted middle plate from the riveting shaft platform.

[0006] By adopting the above technical solutions, the rotating design allows the riveting shaft platform to move flexibly in the equipment, facilitating the operation of each mechanism on the middle plate. Through the fixed shaft mechanism, the shaft rod can be accurately positioned in the fixed shaft hole, providing a basis for subsequent assembly steps. The use of the fixed seat mechanism helps to solve the problem of aligning the aluminum seat with the axis of the shaft rod during manual operation. The introduction of the fixed plate mechanism enables the middle plate to be accurately aligned with the shaft rod and the aluminum seat, further improving the assembly accuracy and efficiency. The use of the riveting mechanism realizes the firm connection of the shaft rod, the aluminum seat and the middle plate. The setting of the material taking mechanism enables the assembled middle plate to be efficiently removed, leaving space for the assembly of the next middle plate and improving the overall production efficiency. Compared with manual assembly, this equipment reduces the dependence on the operator's skills, reduces errors during the assembly process, and improves the assembly efficiency and quality of the cross-flow fan middle plate.

[0007] Optionally, the riveting shaft platform includes a riveting shaft seat, a riveting shaft plate, a first elastic member and a fixed shaft column. The riveting shaft seat is fixed to the top of the turntable. The anchor shaft plate slides relative to the riveting shaft seat. One end of the first elastic member is connected to the riveting shaft seat, and the end of the first elastic member far from the riveting shaft seat is connected to the bottom of the riveting shaft plate. A fixed seat groove matching the aluminum seat is formed on the top wall of the riveting shaft plate. The axis of the fixed shaft hole is collinear with the axis of the fixed seat groove. The fixed shaft column is inserted into the fixed shaft hole and is connected to the riveting shaft seat. The riveting mechanism rivets the shaft rod, the aluminum seat and the middle plate by pressing.

[0008] By adopting the above technical solutions, during the riveting process, the riveting shaft plate can withstand a certain pressure and produce elastic deformation, thereby protecting the aluminum seat and the middle plate from excessive impact force, and at the same time can automatically reset after the riveting is completed, preparing for the next operation. The use of the fixed shaft column enables the stable positioning of the shaft rod during the assembly process, reducing the possibility of the shaft rod offset during the riveting process. The pressing action of the riveting mechanism realizes the firm connection of the shaft rod, the aluminum seat and the middle plate, improving the structural stability and reliability of the assembled parts. At the same time, the buffering effect of the elastic member makes the riveting process proceed smoothly and reduces the damage to the middle plate.

[0009] Optionally, the riveting shaft seat is connected with support columns, which are evenly distributed along the riveting shaft seat. The riveting shaft plate is connected with sliding rods. The support columns are provided with sliding grooves matching the sliding rods, and the sliding rods are inserted into the sliding grooves. The riveting shaft seat is connected with a central rod, and the riveting shaft plate is connected with a central column. The central column is provided with a central groove matching the central rod. The axis of the central groove is collinear with the axis of the positioning groove, and the central rod is inserted into the central groove. A support block is arranged at the bottom of the turntable, and the workbench is connected with a support driving member, which is used to drive the support block to move to the bottom of the riveting shaft seat to support the riveting shaft seat.

[0010] By adopting the above technical solution, the setting of the support block and the support driving member provides additional support for the riveting shaft seat. Especially during the riveting process, in order to rivet the shaft rod, the aluminum seat and the middle plate together, it is necessary to apply a relatively large pressure by the riveting mechanism. At this time, the support block can support the riveting seat, reducing the possibility of deformation of the middle plate caused by uneven stress during riveting, and improving the smoothness of the riveting process and the structural stability of the riveting shaft platform.

[0011] Optionally, the fixed shaft mechanism includes a fixed shaft driving member, a shaft conveying plate, a plastic gasket, a shaft conveying tube, and a shaft pushing assembly. The fixed shaft driving member is connected to the workbench, the output end of the fixed shaft driving member is connected to the shaft conveying plate, the shaft conveying plate is provided with a shaft conveying hole, the plastic gasket is connected to the shaft conveying plate, the plastic gasket is provided with a guide shaft hole, and the axis of the guide shaft hole is collinear with the axis of the shaft conveying hole. The shaft conveying tube is used to convey the shaft rod to the guide shaft hole, and the shaft pushing assembly is used to push the shaft rod located in the guide shaft hole into the fixed shaft hole.

[0012] By adopting the above technical solution, driven by the fixed shaft driving member, the shaft rod is conveyed to the guide shaft hole through the shaft conveying tube. Under the guiding action of the guide shaft hole, the shaft rod moves along the axis of the guide shaft hole and enters the shaft conveying hole. Then the shaft pushing assembly starts to accurately push the shaft rod located in the shaft conveying hole into the fixed shaft hole, completing the positioning and fixing of the shaft rod. By using the plastic gasket, due to the softness of the plastic gasket, it guides the shaft rod into the shaft conveying hole, and at the same time reduces the possibility of damage to the surface of the shaft rod caused by hard contact, improving the surface quality of the shaft rod and the accuracy of assembly.

[0013] Optionally, the workbench is connected with a fixed seat, the shaft conveying plate is slidably connected to the fixed seat, the fixed seat is slidably connected with a limiting rod, the shaft conveying plate is connected with a limiting plate, and the limiting plate is located at the end of the limiting rod away from the turntable.

[0014] By adopting the above technical solution, when the fixed shaft driving member drives the shaft conveying plate to move, the shaft conveying plate drives the limiting plate to move synchronously. After the limiting plate contacts the limiting rod, it pushes the limiting rod to slide until one side of the limiting plate fits against the side of the fixed seat away from the shaft conveying tube, reducing the possibility of deviation in the moving position of the shaft conveying plate.

[0015] Optionally, the fixed seat mechanism includes a fixed seat frame, a sliding block, a first clamping pliers, a fixed aluminum seat, and an aluminum seat conveying channel. The fixed seat frame is connected to the workbench, the sliding block is slidably connected to the fixed seat frame, the first clamping pliers are slidably connected to the sliding block, the fixed aluminum seat is used for positioning the aluminum seat, enabling the first clamping pliers to accurately clamp the aluminum seat, and the aluminum seat conveying channel is used to convey the aluminum seat to the fixed aluminum seat.

[0016] By adopting the above technical solution, the aluminum seat is accurately positioned on the fixed aluminum seat through the guiding of the aluminum seat conveying channel. The first clamping pliers clamp the aluminum seat on the fixed aluminum seat, and the sliding block moves on the fixed seat frame to convey the aluminum seat to the riveting shaft platform, reducing the possibility of deviation in the placement position of the aluminum seat and improving the processing accuracy and product quality.

[0017] Optionally, an aluminum conveying tray is installed on the top of the workbench. A limiting member is fixedly connected to the inner side wall of the aluminum conveying tray. A spiral track is provided inside the aluminum conveying tray. Near the output end of the spiral track, there is a gap between the limiting member and the spiral track for only allowing the large ring of the aluminum seat to pass through. On the side of the spiral track away from the aluminum conveying tray, there is a recessed groove located at the limiting member. The width of the spiral track is smaller than the bottom diameter of the aluminum seat. The output end of the aluminum conveying tray is communicated with the aluminum conveying channel.

[0018] By adopting the above technical solution, when the aluminum seat approaches the limiting member at the top of the spiral track, the large ring of the aluminum seat passes through the gap between the limiting member and the spiral track. Aluminum seats that do not meet the gap height will be blocked and directly fall into the aluminum conveying barrel under the action of the recessed groove, reducing the possibility of inverted or tilted aluminum seats being conveyed to the seat fixing mechanism. Aluminum seats that can pass through the gap continue to be conveyed under the action of the limiting member. At the same time, the limiting member and the spiral track clamp the aluminum seat for conveying, reducing the possibility of the aluminum seat falling into the aluminum conveying barrel when passing through the recessed groove and improving the conveying efficiency of the aluminum seat.

[0019] Optionally, the seat fixing mechanism includes a seat fixing frame, a sliding block and a suction cup. The seat fixing frame is connected to the workbench. The sliding block is slidably connected to the seat fixing frame. The suction cup is slidably connected to the sliding block. The suction cup is used to suck the middle plate to the riveting shaft table.

[0020] By adopting the above technical solution, the sliding block slides on the seat fixing frame and is adjusted to a position corresponding to the middle plate. The suction cup is started. The suction cup generates sufficient suction force. After the suction cup adsorbs the middle plate, the sliding block drives the suction cup and the middle plate to move to the riveting shaft table, completing the conveying process of the middle plate. Through mechanisms such as automatic adsorption, precise positioning and stable conveying, the accuracy and stability of the positioning and conveying of the middle plate are improved.

[0021] Optionally, the workbench is connected with a plate holding seat. A guide rod is connected to the top of the plate holding seat. The guide rod is used to guide the conveying direction of the middle plate. A plate conveying plate is slidably connected to the plate holding seat. The workbench is connected with a plate conveying driving member. The output end of the plate conveying driving member is connected to the plate conveying plate.

[0022] By adopting the above technical solution, under the guiding action of the guide rod, the middle plate moves onto the plate conveying plate. The plate conveying driving member is started to drive the plate conveying plate to be conveyed to the processing position, so that the middle plate is accurately conveyed to the processing position, completing the guiding and conveying process of the middle plate, reducing the deviation or jamming of the middle plate during the conveying process, and improving the reliability of the conveying and the positioning accuracy of the middle plate.

[0023] Optionally, the tray plate is hinged with a first one-way pusher, the tray seat is slidably connected with a clamping assembly, and the first one-way pusher is used to push the clamping assembly to slide so that the clamping assembly clamps the middle plate; the clamping assembly is hinged with a second one-way pusher, and the tray seat is rotatably connected with a pulley assembly. The second one-way pusher is used to push the pulley assembly to drive so that the pulley assembly discharges the middle plate.

[0024] By adopting the above technical solution, when the tray plate moves, it drives the clamping assembly to move, so that the clamping assembly clamps the upper middle plate. At the same time, it pushes the second one-way pusher to move, so that the second one-way pusher acts on the pulley assembly, and the pulley assembly discharges the middle plate, improving the stability of the middle plate placement, reducing the possibility of deviation during riveting caused by the position deviation of the middle plate, and improving the processing accuracy and product quality.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The rotating design allows the riveting shaft platform to move flexibly in the equipment, facilitating the operation of each mechanism on the middle plate. Through the fixed-axis mechanism, the shaft rod can be accurately positioned in the fixed-axis hole, providing a basis for subsequent assembly steps.

The introduction of the fixed-plate mechanism enables the middle plate to accurately align with the shaft rod and the aluminum seat, further improving the assembly accuracy and efficiency. The use of the riveting mechanism realizes the firm connection of the shaft rod, the aluminum seat and the middle plate. The setting of the material-taking mechanism enables the assembled middle plate to be efficiently removed, leaving space for the assembly of the next middle plate and improving the overall production efficiency. Compared with manual assembly, this equipment reduces the dependence on the operator's skills, reduces errors during the assembly process, and improves the assembly efficiency and quality of the middle plate of the cross-flow air wheel; 2. During the riveting process, the riveting shaft plate can withstand a certain pressure and produce elastic deformation, thereby protecting the aluminum seat and the middle plate from excessive impact force. At the same time, it can automatically reset after riveting is completed, preparing for the next operation. The use of the fixed-axis column enables the stable positioning of the shaft rod during the assembly process, reducing the possibility of the shaft rod deviating during riveting. The pressing action of the riveting mechanism realizes the firm connection of the shaft rod, the aluminum seat and the middle plate, improving the structural stability and reliability of the assembled parts. At the same time, the buffering action of the elastic part enables the smooth progress of the riveting process and reduces the damage to the middle plate; 3. When the aluminum seat approaches the limiting part at the top of the spiral track, the large ring of the aluminum seat passes through the gap between the limiting part and the spiral track. The aluminum seat that does not meet the gap height will be blocked and directly fall into the aluminum conveying bucket under the action of the concave groove, reducing the possibility of the inverted or tilted aluminum seat being conveyed to the fixed-seat mechanism; the aluminum seat that can pass through the gap continues to be conveyed under the action of the limiting part. At the same time, the limiting part and the spiral track clamp the aluminum seat for conveying, reducing the possibility of the aluminum seat falling into the aluminum conveying bucket when passing through the concave groove and improving the conveying efficiency of the aluminum seat.

Detailed implementation manners

[0034] The following further elaborates on this application in conjunction with the Figure 1-7 accompanying drawings.

[0035] An embodiment of this application discloses a riveting shaft device for a cross-flow impeller middle plate.

[0036] Referring to Figure 1 , a riveting shaft device for a cross-flow impeller middle plate includes a workbench 1. A turntable 11 is rotatably connected to the top wall of the workbench 1. A rotation driving member is fixedly connected to the bottom of the workbench 1. The output end of the rotation driving member is fixedly connected to the turntable 11. A plurality of riveting shaft platforms 2 are provided on the top of the turntable 11. The riveting shaft platforms 2 are circumferentially distributed equidistantly along the turntable 11. The riveting shaft platforms 2 are close to the edge of the turntable 11. Specifically, in this embodiment, the number of the riveting shaft platforms 2 is 6. A fixed shaft hole 222 is opened on the top wall of the riveting shaft platform 2. A fixed shaft mechanism 3, a fixed seat mechanism 4, a fixed plate mechanism 5, a riveting mechanism 6, and a material taking mechanism 7 are sequentially arranged around the periphery of the turntable 11. Specifically, the fixed shaft mechanism 3 is used to insert a shaft rod into the fixed shaft hole 222. The fixed seat mechanism 4 is used to place an aluminum seat on the riveting shaft platform 2 and make the axis of the aluminum seat collinear with the axis of the shaft rod. The fixed plate mechanism 5 is used to place the middle plate on the riveting shaft platform 2 and make the axis of the middle plate collinear with the axis of the shaft rod. The riveting mechanism 6 is used to rivet the shaft rod, the aluminum seat, and the middle plate after their axes are collinear. The material taking mechanism 7 is used to take out the riveted middle plate from the riveting shaft platform 2. In this embodiment, the rotation driving member adopts a driving motor.

[0037] When assembling the middle plate, the rotation driving member drives the turntable 11 to rotate. The rotation drives the riveting shaft platforms 2 to rotate synchronously. The riveting shaft platforms 2 pass through the fixed shaft mechanism 3, the fixed seat mechanism 4, and the fixed plate mechanism 5, so that the axes of the shaft rod, the aluminum seat, and the middle plate are collinearly arranged. Subsequently, the riveting mechanism 6 rivets the shaft rod, the aluminum seat, and the middle plate to complete the assembly operation of the middle plate. Finally, the material taking mechanism 7 is used to take out the assembled middle plate from the riveting shaft platform 2. Compared with manual assembly, this device reduces the dependence on the operator's skills, reduces the errors during the assembly process, and improves the assembly efficiency and quality of the cross-flow impeller middle plate; at the same time, by providing a plurality of riveting shaft platforms 2, mechanisms such as the fixed shaft mechanism 3, the fixed seat mechanism 4, the fixed plate mechanism 5, the riveting mechanism 6, and the material taking mechanism 7 can operate continuously without waiting for each mechanism to complete the corresponding steps one by one, enabling the assembly operations of multiple middle plates to be carried out synchronously, shortening the assembly time, and further improving the assembly efficiency of the middle plate.

[0038] Referring to Figure 1 and Figure 2, the riveting shaft table 2 includes a riveting shaft seat 21, a riveting shaft plate 22, a first elastic member 23 and a fixed shaft column. The riveting shaft seat 21 is fixed to the top wall of the turntable 11 and near the edge of the turntable 11. The anchor shaft plate slides relative to the riveting shaft seat 21. One bottom end of the first elastic member 23 is fixedly connected to the top wall of the riveting shaft seat 21, and one top end of the first elastic member 23 away from the riveting shaft seat 21 is fixedly connected to the bottom wall of the riveting shaft plate 22. A fixed seat groove 221 matching the diameter of the large ring at the bottom of the aluminum seat is formed on the top wall of the riveting shaft plate 22. The fixed seat groove 221 communicates with a fixed shaft hole 222. The axis of the fixed shaft hole 222 is collinear with the axis of the fixed seat groove 221. After the shaft rod is inserted into the fixed shaft hole 222 and the aluminum seat is placed in the fixed seat groove 221, the axes of the shaft rod and the aluminum seat can be directly collinear without adjusting the positions of the aluminum seat and the shaft rod. The fixed shaft column is inserted into the fixed shaft hole 222 from the bottom of the riveting shaft plate 22. The outer wall of the fixed shaft column fits with the hole wall of the fixed shaft hole 222, and the bottom wall of the fixed shaft column is fixedly connected to the top wall of the riveting shaft seat 21. The riveting mechanism 6 rivets the shaft rod, the aluminum seat and the middle plate by pressing. Specifically, the riveting mechanism 6 includes a riveting frame 61, a riveting driving member 62 and a riveting plate 63. The riveting frame 61 is fixedly connected to the top wall of the workbench 1. The riveting driving member 62 is fixedly connected to the top wall of the riveting frame 61. The output end of the riveting driving member 62 is fixedly connected to the riveting plate 63. A riveting groove matching the aluminum seat and the shaft rod is formed at the bottom of the riveting plate 63, which is convenient for riveting the aluminum seat and the shaft rod. In this example, the riveting driving member 62 is a hydraulic cylinder.

[0039] A fixed seat 31 is fixedly connected to the top wall of the workbench 1. The fixed seat 31 is provided with an orientation groove. The fixed-axis mechanism 3 includes a fixed-axis driving member 32, a shaft-transporting plate 33, a plastic pad 34, a shaft-transporting pipe 35 and a shaft-pushing assembly. The fixed-axis driving member 32 is fixedly connected to the top wall of the workbench 1. The output end of the fixed-axis driving member 32 is fixedly connected to one end side of the shaft-transporting plate 33. The shaft-transporting plate 33 is slidably connected to the groove wall of the orientation groove. A shaft-transporting hole is provided on the top wall of the shaft-transporting plate 33. The plastic pad 34 is fixedly connected to the shaft-transporting plate 33 and is embedded in the shaft-transporting plate 33. A guide shaft hole is penetratingly provided on the top wall of the plastic pad 34. The axis of the guide shaft hole is collinear with the axis of the shaft-transporting hole. The shaft-transporting pipe 35 is used to transport the shaft rod to the guide shaft hole. The output end of the shaft-transporting pipe 35 is fixed to one side of the fixed seat 31 and is arranged vertically at the output end of the shaft-transporting pipe 35, facilitating the transportation of the shaft rod to the guide shaft hole. The shaft-pushing assembly is used to push the shaft rod located in the guide shaft hole into the fixed-axis hole 222. Specifically, the shaft-pushing assembly includes a shaft-pushing frame 36, a shaft-pushing driving member 37, a shaft-pushing plate 371 and a shaft-pushing needle 372. The shaft-pushing frame 36 is fixedly connected to the top wall of the workbench 1. The pushing driving member is fixedly connected to the top of the shaft-pushing frame 36. The output end of the pushing driving member is fixedly connected to the top wall of the shaft-pushing plate 371. The bottom wall of the shaft-pushing plate 371 is fixedly connected to the top wall of the shaft-pushing needle 372. When the riveting shaft plate 22 is located directly below the shaft-pushing driving member 37, the shaft-pushing needle 372 is collinear with the axis of the fixed-axis hole 222. In this embodiment, both the fixed-axis driving member 32 and the shaft-pushing driving member 37 adopt air cylinders.

[0040] When installing the shaft rod, the shaft rod is transported into the guide shaft hole through the shaft-transporting pipe 35. The plastic pad 34 has a soft characteristic. When the shaft rod moves downward under the action of gravity, the shaft rod is guided under the action of the soft characteristic of the plastic pad 34, so that the shaft rod is accurately inserted into the shaft-transporting hole. When one of the riveting shaft plates 22 rotates to directly below the shaft-pushing needle 372 along with the turntable 11, the fixed-axis driving member 32 is started. The fixed-axis driving member 32 drives the shaft-transporting plate 33 to move, so that the shaft-transporting plate 33 moves towards the direction of the riveting shaft plate 22 until the axes of the shaft-transporting hole and the fixed-axis hole 222 are collinear. The shaft-pushing driving member 37 is started. The shaft-pushing driving member 37 drives the shaft-pushing plate 371 to move downward, so that the shaft-pushing needle 372 is inserted into the guide shaft hole, and the shaft rod located in the shaft-transporting hole is pushed into the fixed-axis hole 222, thereby realizing the accurate installation of the shaft rod.

[0041] To improve the conveying accuracy of the shaft conveying plate 33, a limiting rod 331 is slidably connected to one end of the fixed seat 31 away from the turntable 11. A limiting plate 332 is connected to the top wall of the end of the shaft conveying plate 33 away from the fixed seat 31. The limiting plate 332 is located at the end of the limiting rod 331 away from the turntable 11. When the fixed shaft driving member 32 drives the shaft conveying plate 33 to move, the shaft conveying plate 33 drives the limiting plate 332 to move synchronously. After the limiting plate 332 contacts the limiting rod 331, it pushes the limiting rod 331 to slide until one side of the limiting plate 332 fits against the side of the fixed seat 31 away from the shaft pipe 35, reducing the possibility of deviation in the moving position of the shaft conveying plate 33.

[0042] Specifically, a shaft conveying disk 38 is installed on the top of the workbench 1. The output end of the shaft conveying disk 38 is communicated with the shaft pipe 35, so as to automatically feed the shaft rod. In this instance, the shaft conveying disk 38 adopts an existing vibrating disk.

[0043] Refer to Figure 1 and Figure 3 As shown in FIGS. and, the fixed seat mechanism 4 includes a fixed seat frame 41, a sliding block 42, a first clamping pliers 43, a fixed aluminum seat 44 and an aluminum conveying channel 45. The fixed seat frame 41 is fixedly connected to the top wall of the workbench 1. The sliding block 42 is slidably connected to the fixed seat frame 41. In this instance, the sliding block 42 is driven by a motor to rotate the lead screw, thereby driving the sliding block 42 to horizontally slide along the fixed seat frame 41. A fixed seat driving member 46 is fixedly connected to one side of the sliding block 42. The output end of the fixed seat driving member 46 is fixedly connected to the first clamping pliers 43. The first clamping pliers 43 vertically slide on the sliding block 42 through the fixed seat driving member 46. The fixed aluminum seat 44 is used for positioning the aluminum seat, so that the first clamping pliers 43 can accurately clamp the aluminum seat. The aluminum conveying channel 45 is used for conveying the aluminum seat to the fixed aluminum seat 44. In this instance, the fixed seat driving member 46 adopts a cylinder, and the first clamping pliers 43 clamp the aluminum seat in a pneumatic manner.

[0044] A aluminum conveying disk 47 is installed on the top of the workbench 1. A limiting member 48 is fixedly connected to the inner side wall of the aluminum conveying disk 47. A spiral track 49 is provided in the aluminum conveying disk 47. The limiting member 48 is protrudingly arranged above the conveying direction of the spiral track 49 and near the output end of the spiral track 49. There is a gap between the bottom wall of the limiting member 48 and the top wall of the spiral track 49 for only the large ring of the aluminum seat to pass through. A concave groove 491 is provided on the side of the spiral track 49 away from the aluminum conveying disk 47. The concave groove 491 is located at the position of the limiting member 48. The track width of the spiral track 49 is smaller than the bottom diameter of the aluminum seat, so that the aluminum seat that does not meet the clamping state for the first clamping pliers 43 can fall from the spiral track 49. The output end of the aluminum conveying disk 47 is communicated with the aluminum conveying channel 45, so as to automatically feed the aluminum seat.

[0045] Refer to Figure 1 and Figure 4The disk fixing mechanism 5 includes a disk fixing frame 51, a sliding block 52, and a suction cup 53. The disk fixing frame 51 is fixedly connected to the top wall of the workbench 1. The sliding block 52 is slidably connected to the disk fixing frame 51. In this example, the sliding block 52 is driven by a motor to rotate a lead screw, thereby driving the sliding block 52 to perform horizontal sliding along the disk fixing frame 51. The suction cup 53 is slidably connected to the sliding block 52. A disk fixing driving member 54 is fixedly connected to one side of the sliding block 52. The output end of the disk fixing driving member 54 is fixedly connected to the suction cup 53. The suction cup 53 vertically slides on the sliding block 52 through the disk fixing driving member 54. In this embodiment, the disk fixing driving member 54 is a cylinder. The suction cup 53 is used to suck the middle disk to the riveting shaft table 2.

[0046] A disk holding seat 55 is fixedly connected to the top wall of the workbench 1. An annular disk dropping groove is formed through the top wall of the disk holding seat 55. A plurality of guide rods 56 are fixedly connected to the top wall of the disk holding seat 55. The guide rods 56 are circumferentially and equidistantly distributed along the axis of the disk dropping groove, enclosing a guide channel for guiding the conveying direction of the middle disk. The guide channel communicates with the disk dropping groove. A disk conveying plate 57 is slidably connected to the disk holding seat 55. A disk conveying driving member 571 is fixedly connected to the top wall of the workbench 1. The output end of the disk conveying driving member 571 is fixedly connected to one end of the disk conveying plate 57. In this example, the disk conveying driving member 571 is a cylinder.

[0047] To accurately position the middle disk so that when the suction cup 53 adsorbs the middle disk, the suction cup 53 adsorbs at the same position on different middle disks each time, a semi-circular arc groove 551 matching the arc of the middle disk is formed in the disk holding seat 55. The semi-circular arc groove 551 is located directly below the horizontal movement direction of the suction cup 53. A disk placing groove 572 is formed in the disk conveying plate 57.

[0048] When installing the middle disk, the middle disk drops from the disk dropping groove into the disk placing groove 572. The disk conveying driving member 571 is started. The disk conveying driving member 571 drives the disk conveying plate 57 to move towards the disk fixing frame 51 until one end of the middle disk away from the groove wall of the disk placing groove 572 is inserted into the semi-circular arc groove 551. The outer wall of the middle disk fits against the groove wall of the semi-circular arc groove 551 and the vertical groove wall of the disk placing groove 572, thereby positioning the position of the middle disk. The suction cup 53 is slid to directly above the middle disk. The disk fixing driving member 54 is started. The disk fixing driving member 54 drives the suction cup 53 to move towards the middle disk. The suction cup 53 adsorbs the middle disk. After adsorption, the suction cup 53 rises under the action of the disk fixing driving member 54. Subsequently, under the action of the motor and the lead screw, the sliding block 52 is driven to slide, so that the middle disk moves to directly above the riveting shaft plate 22 already installed with an aluminum seat. The suction cup 53 descends under the action of the disk fixing driving member 54, and the middle disk is placed on the aluminum seat, thereby realizing the installation of the middle disk and improving the accuracy of the middle disk installation.

[0049] Further, for facilitating the middle plate to fall into the placing groove 572 and reducing the wear on the middle plate, the feeding plate 57 is hinged with a first one-way pusher 58. One side of the first one-way pusher 58 is connected with an elastic cord. The end of the elastic cord far from the first one-way pusher 58 is fixedly connected with the feeding plate 57. The first one-way pusher 58 protrudes from the top wall of the feeding plate 57. The first one-way pusher is vertically arranged through the elastic cord. At this time, the first one-way pusher 58 abuts against the vertical groove wall of the placing groove 572 away from the semi-arc groove 551. The tray holder 55 is slidably connected with a clamping assembly. The clamping assembly includes a clamping member 581 and a second elastic member 582. The clamping member 581 is slidably connected with the tray holder 55. One end of the second elastic member 582 is fixedly connected with the clamping member 581. The end of the second elastic member 582 far from the clamping member 581 is fixedly connected with the tray member. Thus, the clamping member 581 moves reciprocally. The first one-way pusher 58 is used to push the clamping member 581 to slide, so that the clamping member 581 clamps the middle plate. One end of the clamping member 581 close to the first one-way pusher is arranged in an arc shape, which is convenient for the first one-way pusher 58 to push the clamping member 581 to slide; a hinge groove is formed at the bottom of the clamping member 581. The clamping member 581 is hinged with a second one-way pusher 59. When the second one-way pusher 59 is vertically arranged, one side of the second one-way pusher 59 abuts against the vertical groove wall of the hinge groove. And the vertical groove wall of the hinge groove is located between the second one-way pusher 59 and the first one-way pusher 58. The tray holder 55 is rotatably connected with a pulley assembly. The second one-way pusher 59 is used to push the pulley assembly to drive, so that the pulley assembly discharges the middle plate.

[0050] Referring to Figure 5 and Figure 6 , specifically, the pulley assembly includes a tension pulley 591, a tension belt 592, a support plate 593, a positioning rod 594, a partition member 595 and a third elastic member. The tension pulley 591 is rotatably connected with the tray holder 55. The number of the tension pulleys 591 is two, and they are vertically distributed. The tension belt 592 is looped around the two tension pulleys 591. When the tension pulley 591 rotates, it drives the tension pulley 591 to rotate. The support plate 593 is located between the two tension pulleys 591 and is attached to the tension belt 592 for supporting the inner wall of the tension belt 592. The support plate 593 is fixedly connected with the tray holder 55. One end of the positioning rod 594 is fixedly connected with the outer wall of the tension pulley 591. The number of the positioning rods 594 is multiple, and they are circumferentially equidistantly distributed along the outer wall of the tension pulley 591. The partition member 595 is slidably connected with the tray holder 55. One end of the third elastic member is fixedly connected with the partition member 595. The end of the third elastic member far from the partition member 595 is fixedly connected with the tray holder 55. The partition member 595 is reset through the third elastic member, so that the partition member 595 blocks and positions the positioning rod 594. In this embodiment, the first elastic member 23, the second elastic member 582 and the third elastic member all adopt springs.

[0051] When discharging the middle plate, when the tray driving member 571 drives the tray plate 57 away from the semi-circular groove 551, the first one-way pushing member 58 is pushed by the limiting effect of the wall of the disk placing groove 572 to drive the clamping member 581 to slide, and the clamping member 581 clamps the middle plate. At the same time, the second one-way pushing member 59 is pushed by the limiting effect of the wall of the hinge groove to drive the blocking member 595 to slide, and the extended blocking member 595 limits the positioning rod 594. The second one-way pushing member 59 continuously pushes, so that the second one-way pushing member 59 pushes the positioning member, so that the tensioning wheel 591 rotates, driving the tensioning belt 592 to drive, so that the middle plate at the bottom drops into the disk placing groove 572. Similarly, when the tray driving member 571 drives the tray plate 57 close to the semi-circular groove 551, the first one-way pushing member 58 is in a free state, the clamping member 581 is reset, the clamping member 581 pushes the first one-way pushing member 58 to rotate by hinge, the second one-way pushing member 59 is in a free state, the blocking member 595 is reset, the blocking member 595 pushes the second one-way pushing member 59 to rotate by hinge, and the blocking member 595 limits the positioning rod 594, so as to realize the automatic dropping operation of the middle plate, which is convenient and fast.

[0052] Refer to Figure 2 and Figure 7 As shown in [figures] and [figures], a support column 8 is fixedly connected to the top wall of the riveting shaft seat 21. The support columns 8 are equidistantly distributed along the riveting shaft seat 21. A sliding rod 81 is connected to the bottom wall of the riveting shaft plate 22. The support column 8 is provided with a sliding groove matching the sliding rod 81, and the sliding rod 81 is inserted into the sliding groove. A central rod 82 is fixedly connected to the top wall of the riveting shaft seat 21. A central column 83 is fixedly connected to the bottom wall of the riveting shaft plate 22. The central column 83 is provided with a central groove matching the central rod 82. The axis of the central groove is collinear with the axis of the positioning groove, and the central rod 82 is inserted into the central groove. A support block 84 is provided at the bottom of the turntable 11. A support driving member 85 is fixedly connected to the top wall of the workbench 1. The support driving member 85 is used to drive the support block 84 to move to the bottom of the riveting shaft seat 21, so that the support block 84 supports the riveting shaft seat 21. Specifically, a sliding table 86 is fixedly connected to the top wall of the workbench 1. The sliding groove is located at the bottom of the turntable 11. The top wall of the sliding table 86 is provided with an inclined groove. The groove wall of the inclined groove away from the turntable 11 is inclined. The support block 84 is slidably connected with a connecting plate, and the connecting plate is fixedly connected to the output end of the support driving member 85. When the support driving member 85 drives the connecting plate to move towards the turntable 11, the support block 84 slides with the connecting plate, and the bottom wall of the support block 84 slides with the inclined side of the groove wall of the inclined groove, so that the support block 84 rises and gradually approaches the bottom wall of the turntable 11 until the top wall of the support block 84 tightly abuts against the bottom wall of the turntable 11, so as to support the shaft rod, the aluminum seat and the middle plate during riveting, reducing the possibility of errors in riveting.

[0053] The material taking mechanism 7 includes a material taking frame 71, a first driving member 72, a material taking block 73, a second driving member 74, and a second clamping pliers 75. The material taking frame 71 is fixed on the top wall of the workbench 1. The first driving member 72 is fixed on the top of the material taking frame 71. The output end of the first driving member 72 is fixedly connected to the material taking block 73. The second driving member 74 is fixedly connected to the material taking block 73. The output end of the second driving member 74 is fixedly connected to the second clamping pliers 75. Both the first driving member 72 and the second driving member 74 are cylinders. The second clamping pliers 75 clamp the aluminum seat with the middle plate installed in a pneumatic manner.

[0054] After the middle plate is assembled, start the first driving member 72. The first driving member 72 drives the material taking block 73 to move horizontally until it moves to the top of the riveting shaft plate 22. Then start the second driving member 74. The second driving member 74 drives the second clamping pliers 75 to descend, so that the second clamping pliers 75 move towards the middle plate direction. The second clamping pliers 75 clamp the middle plate. Subsequently, by starting the second driving member 74 and the first driving member 72 successively, the second clamping pliers 75 are moved away from the riveting shaft plate 22, thereby realizing the material taking process of the middle plate, which is convenient and fast.

[0055] The implementation principle of the riveting shaft device for the cross-flow fan middle plate in the embodiment of the present application is as follows: When assembling the middle plate, the turntable 11 rotates. When the riveting shaft plate 22 rotates to the fixed shaft mechanism 3, the shaft driving member drives the shaft plate 33 to move to the top of the riveting shaft plate 22. The push shaft driving member 37 drives the push shaft plate 371 to move downwards, so that the push shaft needle 372 is inserted into the guide shaft hole, and the shaft rod located in the shaft hole is pushed into the fixed shaft hole 222. The riveting shaft plate 22 with the shaft rod installed rotates to the fixed seat mechanism 4. The sliding block 42 drives the first clamping pliers 43 to slide on the fixed seat frame 41, so that the first clamping pliers 43 clamp the aluminum seat on the fixed aluminum seat 44 to the fixed seat groove 221. The riveting shaft plate 22 with the aluminum seat installed rotates to the fixed plate mechanism 5. The sliding block 52 drives the suction cup 53 to slide on the fixed plate frame 51, so that the suction cup 53 sucks the middle plate against the semi-circular groove 551 onto the riveting shaft plate 22. The middle plate is placed on the aluminum seat. The riveting shaft plate 22 with the middle plate installed rotates to the riveting mechanism 6. The riveting driving member 62 drives the riveting plate 63 to descend. The riveting plate 63 fits against the middle plate to perform horizontal adjustment on the middle plate. The riveting plate 63 continues to descend, pressing the riveting shaft plate 22, so that the riveting shaft plate 22 descends, and thus the shaft rod protrudes from the fixed shaft hole 222. The shaft rod is inserted into the aluminum seat, so that the shaft rod, the aluminum seat and the middle plate are riveted together, thereby improving the assembly efficiency of the middle plate.
