[0001] This application relates to the technical field of production equipment for motors, and in particular to production equipment for a planetary gear reduction motor. Background Art

[0002] During the production process of a motor, components need to be assembled. Through automated motor production equipment, automated assembly can be carried out during the motor assembly process, improving production efficiency and reducing the labor intensity of manual operations at the same time. For a planetary gear reduction motor, there are multiple planetary gears inside, and the planetary gears are connected to a planet carrier, enabling the assembly of multiple planetary gears with the planet carrier.

[0003] A multifunctional planetary gear assembly device is disclosed in the related art, including a processing table. The processing table includes a support frame I arranged on one side of the processing table, an oil injection support assembly arranged on the other side of the processing table, a support frame II arranged at the rear of the processing table, and a turntable installed on the top surface of the processing table. At the top of the support frame I, there are a placement plate for the bottom layer gears and a planetary gear vibrating disk I and a gear vibrating disk I for the assembly of the middle layer gears. At the top of the support frame II, there are a planetary gear vibrating disk II and a gear vibrating disk II for the assembly of the top layer gears. During the assembly process, the turntable rotates to at least different stations for installing multiple planetary gears in sequence.

[0004] However, in the above structure, multiple planetary gears correspond to multiple identical installation stations. Summary of the Invention

[0005] In order to reduce the installation stations corresponding to the planetary gears, this application provides production equipment for a planetary gear reduction motor.

[0006] This application provides production equipment for a planetary gear reduction motor, adopting the following technical solutions:

[0007] A production equipment for a planetary gear reduction motor includes a frame. On the frame, there are a loading table, a first vibrating disk, a second vibrating disk, and a vertical cylinder. The first vibrating disk is used for loading snap rings; the second vibrating disk is used for loading planetary gears, and the vertical cylinder is used for loading bearings. The loading table is used for loading planet carriers; on the frame, there is a sub-assembly table group for assembling planetary gears, bearings, and snap rings. A general assembly table and a robotic arm are installed on the frame. The robotic arm is used to pick up the planet carrier on the loading table and place it flat on the general assembly table, and then sequentially pick up the assembled units of planetary gears, bearings, and snap rings formed on multiple sub-assembly table groups and assemble them on the planet carrier on the general assembly table.

[0008] By adopting the above technical solution, during use, the planetary carrier is placed on the loading table, the circlips are loaded on the first vibrating bowl, the planetary gears are loaded on the second vibrating bowl, the vertical cylinder is used for loading bearings, and after assembling a bearing, a planetary gear and a circlip into a whole on the sub-assembly table group, the planetary carrier is placed on the general assembly table by the robotic arm. At the same time, the robotic arm clamps the assembled planetary gear, bearing and circlip onto the planetary carrier, and clamps three in sequence, so that the installation stations of the three planetary gears are completed on one general assembly table, reducing the installation stations corresponding to the planetary gears.

[0009] Preferably, the sub-assembly table group includes a table frame, a turntable and a rotating cylinder. The table frame is fixed on the machine frame, the rotating cylinder is fixed on the table frame, and the output axis of the rotating cylinder is vertically arranged; the turntable is fixed at the output end of the rotating cylinder; two positioning rods are fixedly arranged on the upper surface of the turntable, and the two positioning rods exchange positions when the rotating cylinder works; a pressing device for installing the bearing is correspondingly arranged on one of the positioning rods, and a clamping device for installing the circlip is correspondingly arranged on the other positioning rod.

[0010] By adopting the above technical solution, the turntable is rotatably arranged on the table frame through the rotating cylinder. When the turntable rotates through the rotating cylinder, the installation positions of the bearing and the circlip of the planetary gear can be respectively located at the two positioning rods, and the two positioning rods that exchange positions can install the circlip and the bearing simultaneously, improving the installation speed of the bearing and the circlip on the planetary gear.

[0011] Preferably, a linear slide module is installed on the machine frame; a lifting chuck is installed at the output part of the linear slide module; when the linear slide module drives the lifting chuck to move to both ends of the linear slide module, it corresponds to the positioning rod and the discharge end of the second vibrating bowl respectively; when the lifting chuck is located at the middle position of the linear slide module, it corresponds to the discharge positions of multiple vertical cylinders; the lifting chuck first clamps a bearing flowing out of a vertical cylinder, and then moves to the corresponding position of the second vibrating bowl and simultaneously clamps the bearing and the planetary gear arranged up and down.

[0012] By adopting the above technical solution, after the lifting chuck moves away from the direction of the positioning rod, it first passes through the position of the vertical cylinder where the bearing flows out and clamps a bearing, then places the bearing on the planetary gear, and then clamps the planetary gear and the bearing and moves them simultaneously. Furthermore, during the process of the linear slide module driving the lifting chuck to make a round trip, the picking and placing of the planetary gear and the bearing can be completed.

[0013] Preferably, the pressing device includes a pressing head and a pressing cylinder; the pressing head is used for sleeving on the positioning rod to squeeze the bearing; the pressing cylinder is fixedly installed at the output end of the pressing cylinder.

[0014] By adopting the above technical solution, the indenter is used to be sleeved on the positioning rod. Thus, under the action of the pressing cylinder, the indenter is sleeved on the positioning rod so that the lower end of the indenter abuts against the bearing. Through the cooperation of the indenter and the positioning rod, the extrusion direction of the indenter on the bearing can be relatively accurate, improving the press-fitting quality of the bearing.

[0015] Preferably, the clamping device includes a clamping cylinder, a pressing cylinder, a tightening block and a tightening cylinder; a vertical tightening hole is provided on the tightening block; a chamfer is provided at the upper end edge of the tightening hole; the clamping cylinder is fixed on the frame and is used to drive the pressing cylinder to insert into the tightening hole; the tightening cylinder is used to drive the tightening block to abut against the end of the planetary gear.

[0016] By adopting the above technical solution, a chamfer is provided at the upper end edge of the tightening hole. After the snap ring is placed at the position of the chamfer, the pressing cylinder approaches the position of the snap ring and causes the snap ring to shrink into the tightening hole. At the same time, the tightening hole and the inner hole of the bearing are docked through the tightening cylinder, thus facilitating the snap ring to enter into the inner hole of the bearing from the tightening hole.

[0017] Preferably, a plug rod is rotatably installed on the bench, and the plug rod is vertically slidably matched with the bench; the plug rod is connected with a positioning cylinder for driving the plug rod to move vertically; two positioning holes are provided on the turntable; the upper end of the plug rod is used to be inserted into the positioning holes in a matching manner.

[0018] By adopting the above technical solution, the plug rod is vertically slidably matched with the bench. When the turntable rotates to the position for installing the snap ring, the positioning cylinder drives the plug rod to insert into the positioning holes, thereby fixing the position of the turntable by the plug rod and reducing the rotation of the turntable during the press-fitting process.

[0019] Preferably, a discharge block is fixedly arranged at the lower end of the vertical cylinder; a through hole is provided on the discharge block; a push strip plate is slidably matched in the through hole, and the push strip plate is connected with a pushing cylinder for driving the push strip plate to slide along the through hole; the push strip plate is used to open or block the lower end of the vertical cylinder.

[0020] By adopting the above technical solution, a through hole is provided on the discharge block, and the push strip plate can enter the through hole. Thus, the push strip plate reciprocates in the through hole under the action of the pushing cylinder, enabling the push strip plate to open or block the lower end of the vertical cylinder. When opening the lower end of the vertical cylinder, one bearing in the vertical cylinder falls into the through hole, and then the lower end of the vertical cylinder is blocked, thus facilitating the bearings in the vertical cylinder to flow out one by one.

[0021] Preferably, a moving device is arranged between the first vibrating bowl and the tightening block; the moving device includes a horizontal cylinder and a vertical cylinder; the output end of the horizontal cylinder is used to install the vertical cylinder; the output end of the vertical cylinder is installed with a magnetic suction head; the magnetic suction head is of a hollow structure; the magnetic suction head sucks the snap ring discharged from the first vibrating bowl and moves it to the tightening hole of the tightening block.

[0022] By adopting the above technical solution, the horizontal cylinder is used to drive the magnetic suction head to move towards the tightening block, and the vertical cylinder is used to drive the magnetic suction head to move in the vertical direction. After the magnetic suction head sucks the snap ring, the magnetic suction head can move to the position of the tightening hole, and then directly insert the pressing cylinder through the hollow position of the magnetic suction head, so that the magnetic suction head and the tightening block can control the snap ring and reduce the snap ring from flying out under pressure.

[0023] Preferably, a sliding block is arranged at the discharging position of the first vibrating bowl; a receiving groove connected to the discharging position of the first vibrating bowl is opened on the block; a plugging cylinder for driving the block to move is connected to the block.

[0024] By adopting the above technical solution, the block is arranged at the discharging position of the first vibrating bowl. The receiving groove opened on the block can receive the snap ring flowing out of the first vibrating bowl. Then, after the plugging cylinder moves the block away, only one snap ring remains in the receiving groove, which is convenient for the magnetic suction head to accurately suck one snap ring from the receiving groove.

[0025] Preferably, a transition device is arranged on the frame; the transition device includes a first moving table and a second moving table. A flipping cylinder is installed on the first moving table; a rotating chuck is fixedly arranged at the output part of the flipping cylinder; the rotating chuck moves to the subassembly table group through the first moving table to clamp the assembled planetary gear, bearing and snap ring as a whole; the rotating chuck rotates the planetary gear through the flipping cylinder until the snap ring is located below the bearing; the rotating chuck is used to place the flipped planetary gear on the second moving table and convey it to the clamping position of the robotic arm.

[0026] By adopting the above technical solution, the flipping cylinder first moves to the position of the assembled planetary gear, bearing and snap ring as a whole through the first moving table, then clamps and rotates to the position where the snap ring is located below the bearing by the flipping cylinder, and then places it on the second moving table, which is convenient for the robotic arm to directly clamp the planetary gear with the correct orientation.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The planetary carrier is placed on the general assembly table by the robotic arm, and at the same time, the robotic arm clamps the assembled planetary gear, bearing and snap ring onto the planetary carrier, and clamps three in sequence, so that the installation stations of the three planetary gears are completed on one general assembly table, reducing the installation stations corresponding to the planetary gears;

[0029] After moving away from the positioning rod through the lifting chuck, first pick up a bearing, then place the bearing on the planetary gear, and then pick up the planetary gear and the bearing and move them simultaneously. During one round trip of the lifting chuck, the picking and placing of the planetary gear and the bearing can be completed, improving work efficiency and leaving time for pressing the bearing at the same time;

[0030] After sucking the snap ring through the magnetic head, the magnetic head can move to the position of the tightening hole, and the hollow position of the magnetic head is directly inserted into the pressing cylinder, enabling the magnetic head and the tightening block to control the snap ring and reducing the risk of the snap ring flying out under pressure.

[0044] Refer to Figure 1 , the planetary gear 11 reduction motor includes a planet carrier 1 and three planet gears 11 mounted on the planet carrier 1. The planet carrier 1 is a disc-shaped structure. Three mounting posts 12 perpendicular to the planet carrier 1 are integrally provided on one surface of the planet carrier 1. The mounting posts 12 are used for sleeving the planet gears 11. A bearing 13 is provided between the planet gear 11 and the mounting post 12. The bearing 13 is used to rotatably connect the planet gear 11 to the mounting post 12. A snap ring 14 is provided at one end of the planet gear 11. The snap ring 14 is stuck on the inner side wall of the planet gear 11. The end face of the bearing 13 abuts against the snap ring 14, so that the position of the bearing 13 and the planet gear 11 is positioned by the snap ring 14. The snap ring 14 is located at one end face of the bearing 13 facing the surface of the planet carrier 1, so that the snap ring 14 abuts against the outer ring of the bearing 13. A screw 15 is threadedly connected to the end of the mounting post 12 away from the planet carrier 1. The head of the screw 15 is used to abut against the inner ring of the bearing 13, so that the bearing 13 is stably connected to the mounting post 12 through the snap ring 14 and the screw 15. At the same time, the planet gear 11 is stably connected to the bearing 13 through the snap ring 14. A central gear 16 is integrally provided on the surface of the planet carrier 1 facing away from the planet gear.

[0045] An embodiment of the present application discloses a production device for a planetary gear reduction motor.

[0046] Embodiment 1:

[0047] This embodiment discloses a production device for a planetary gear reduction motor. Refer to Figure 2 and Figure 3 , which includes a loading table 21 for loading the planet carrier 1, a first vibrating bowl 22 for loading the snap ring 14, a second vibrating bowl 23 for loading the planetary gear 11, and a vertical cylinder 24 for loading the bearing 13. The loading table 21, the first vibrating bowl 22, the second vibrating bowl 23, and the vertical cylinder 24 are all installed on the frame 3. A sub-assembly table group 4 is provided on the frame 3, and the position of the sub-assembly table group 4 is used for assembling the planetary gear 11 and the bearing 13. A robotic arm 31 is installed on the frame 3, and the robotic arm 31 is used to move the single planetary gear 11 and bearing 13 assembled by the sub-assembly table group 4. A general assembly table 32 is provided on the frame 3. The planet carrier 1 is placed flat on the upper part of the general assembly table 32, and the mounting posts 12 on the planet carrier 1 are vertically upward. The robotic arm 31 moves the single planetary gear 11 and bearing 13 to the positions corresponding to the mounting posts 12 and presses them onto the mounting posts 12. After the robotic arm 31 works continuously three times, all three mounting posts 12 can be assembled with the planetary gear 11. A screw tightening device 33 is provided on the frame 3, and the screws 15 on each mounting post 12 are installed through the screw tightening device 33.

[0048] Refer to Figure 4, the sub-packaging table group 4 includes a table frame 41, a turntable 42 and a rotating cylinder 43. The rotating cylinder 43 is fixed on the upper surface of the table frame 41 and its output axis is vertically arranged. The output part of the rotating cylinder 43 is fixed with the turntable 42. Each time the rotating cylinder 43 works, the rotation angle is 180 degrees, so that the rotating cylinder 43 drives the turntable 42 to rotate. Two positioning rods 44 are fixedly arranged on the turntable 42. The positioning rods 44 are vertically arranged. The lower ends of the positioning rods 44 are connected to the turntable 42, and the upper ends are used for sleeving the planetary gear 11 and the bearing 13. The two positioning rods 44 are respectively at the positions relative to 180 degrees on the turntable 42, so that the positions of the two positioning rods 44 can be interchanged each time the rotating cylinder 43 works. A plug rod 45 is slidably connected to the table frame 41. The plug rod 45 is vertically arranged. The lower end of the plug rod 45 is connected with a positioning cylinder 46. The output end of the positioning cylinder 46 is connected with the plug rod 45. The positioning cylinder 46 is used to drive the plug rod 45 to reciprocate vertically. Two positioning holes 47 are opened on the turntable 42. The positioning holes 47 are used to cooperate with the upper end of the plug rod 45. When the turntable 42 is driven to rotate by the rotating cylinder 43, one of the positioning holes 47 can just be directly above the plug rod 45, and then the plug rod 45 is moved upward by the positioning cylinder 46 and inserted into the positioning hole 47, so as to position the position of the turntable 42 by the plug rod 45, which is convenient for keeping the position of the positioning rod 44 stable. Two support wheels 48 are rotatably installed on the table frame 41. The support wheels 48 are located directly below the two positioning rods 44 when they stop rotating. The upper part of the side wall of the support wheel 48 supports on the lower surface of the turntable 42. On the one hand, when the turntable 42 is subjected to the pressure when installing the bearing 13, the support wheel 48 can provide a reaction force to the turntable 42 to reduce the damage of the rotating cylinder 43. On the other hand, when the turntable 42 rotates to the position of the support wheel 48 during the rotation process, the lower surface of the turntable 42 can be in contact with the support wheel 48, making it easier for the turntable 42 to rotate to the upper position of the support wheel 48.

[0049] Reference Figure 5 and Figure 6, a press-fitting device 5 is arranged on the frame 3, and the press-fitting device 5 corresponds to the position of one of the positioning rods 44 for press-fitting the bearing 13 into the interior of the planetary gear 11. A clamping device 6 is fixedly arranged on the frame 3, and the clamping device 6 corresponds to the position of the other positioning rod 44 for clamping the snap ring 14 into the interior of the planetary gear 11. A linear slide module 34 is installed on the frame 3, and a lifting chuck 341 that is translated by the linear slide module 34 is installed on the linear slide module 34. The lifting chuck 341 can be driven by a cylinder to lift. When the lifting chuck 341 moves to the end of the linear slide module 34 through the linear slide module 34, the lifting chuck 341 is directly above the positioning rod 44 corresponding to the press-fitting device 5; when the lifting chuck 341 moves to the starting end of the linear slide group through the linear slide module 34, the lifting chuck 341 is above the discharging end of the second vibrating disk 23. When the lifting chuck 341 moves to the middle position of the linear slide module 34, it corresponds to a plurality of vertical cylinders 24 in sequence. In this embodiment, four vertical cylinders 24 are provided.

[0050] Reference Figure 6 and Figure 7, a discharge block 241 is fixedly arranged at the lower end of the vertical cylinder 24. A through hole 242 is formed in the discharge block 241. The height of the through hole 242 is equal to the width of a bearing 13. The bearing 13 placed in the vertical cylinder 24 can descend along the vertical cylinder 24. A push bar plate 243 is arranged in the through hole 242. One end of the push bar plate 243 is inserted into the through hole 242, and the other end is connected with a push cylinder 244. The output direction of the push cylinder 244 is the same as the length direction of the through hole 242, so that the push cylinder 244 can drive the push bar plate 243 to move along the through hole 242. The height of the push bar plate 243 is equal to the height of the through hole 242. After the push bar plate 243 pushes a bearing 13 leaking from the vertical cylinder 24 to the bottom surface of the through hole 242 to the end of the through hole 242, at the same time, the push bar plate 243 blocks the lower end of the vertical cylinder 24. Then, after the push bar plate 243 is retracted by the push cylinder 244, the push bar plate 243 opens the lower end of the vertical cylinder 24, and another bearing 13 leaks from the inside of the vertical cylinder 24, so that only one bearing 13 flows out of the through hole 242 each time. The end position of the through hole 242 exposes the bearing 13 from above, and the lifting chuck 341 can move to directly above the bearing 13, that is, during the movement of the lifting chuck 341 on the linear slide module 34, it can successively pass above a positioning rod 44, above four bearings 13 flowing out of the vertical cylinder 24, and above the planetary gears 11 flowing out of the second vibrating disk 23. During use, first move the lifting chuck 341 above the positioning rod 44, and place the bearing 13 and the planetary gear 11 from top to bottom on the positioning rod 44 by the lifting chuck 341 with the bearing 13 and the planetary gear 11. Then move to the position of the bearing 13 flowing out of a vertical cylinder 24 in the middle of the linear slide module 34, and clamp a bearing 13 by the lifting chuck 341. The lifting chuck 341 moves the bearing 13 to directly above the planetary gear 11 flowing out of the second vibrating disk 23, places the bearing 13 on the planetary gear 11, and then the lifting chuck 341 clamps the planetary gear 11 again. At the same time, move the bearing 13 and the planetary gear 11 to directly above the positioning rod 44 again, so that the lifting chuck 341 can install the bearing 13 and the planetary gear 11 on the positioning rod 44 simultaneously during one round trip.

[0051] Reference Figure 6 and Figure 8, the press-fitting device 5 includes a punch 51 and a clamping cylinder 52. The clamping cylinder 52 is vertically fixed on the frame 3. The clamping cylinder 52 is located directly above the positioning rod 44. A moving block 53 is fixedly arranged at the output end of the clamping cylinder 52. The punch 51 is cylindrical. The punch 51 is vertically fixed on the moving block 53. The center of the punch 51 coincides with the center of the positioning rod 44. After the bearing 13 and the planetary gear 11 are placed on the positioning rod 44 by the lifting chuck 341, the bearing 13 does not enter the interior of the planetary gear 11. The punch 51 moves vertically downward, and the punch 51 is sleeved on the positioning rod 44. At the same time, the end of the punch 51 abuts against the bearing 13, so that the bearing 13 is extruded into the interior of the planetary gear 11, thereby installing the bearing 13 into the planetary gear 11. Then, the planetary gear 11 with the installed bearing 13 rotates 180 degrees with the turntable 42 and reaches directly below the clamping device 6.

[0052] Reference Figure 9, the clamping device 6 includes a clamping cylinder 61, a pressing cylinder 62, a tightening block 63 and a tightening cylinder 64. A first slider 65 is connected to the tightening block 63, and a second slider 66 is connected to the pressing cylinder 62. A slide rail 67 is fixedly arranged on the frame 3. The slide rail 67 is vertically arranged. The first slider 65 and the second slider 66 are slidably connected to the slide rail 67, and the first slider 65 is located below the second slider 66. The tightening cylinder 64 is fixed on the second slider 66, and the output part of the tightening cylinder 64 is fixedly connected to the first slider 65. The clamping cylinder 61 is fixed at the upper end of the slide rail 67, and the output part of the clamping cylinder 61 is fixed on the second slider 66. When the clamping cylinder 61 works, the clamping cylinder 61 can drive the first slider 65 and the second slider 66 to move simultaneously. When the tightening cylinder 64 works, the tightening cylinder 64 only drives the first slider 65 to move. The tightening block 63 is fixed on the first slider 65 and can move along with the first slider 65. A tightening hole 68 is formed in the tightening block 63. The tightening hole 68 is vertically arranged, and the diameter of the tightening hole 68 is equal to the inner diameter of the planetary gear 11. The lower surface of the tightening block 63 is used to abut against the end face of the planetary gear 11, so that the tightening hole 68 on the tightening block 63 is aligned with the inner hole of the planetary gear 11. The inner diameter of the pressing cylinder 62 is equal to the outer diameter of the positioning rod 44, and at the same time, the outer diameter of the pressing cylinder 62 is equal to the inner diameter of the tightening hole 68. In use, first insert the pressing cylinder 62 into the tightening hole 68, then the clamping cylinder 61 drives the pressing cylinder 62 and the tightening block 63 to move downward simultaneously, and through the cooperation between the pressing cylinder 62 and the positioning rod 44, the center of the tightening hole 68 is aligned with the center of the planetary gear 11. Then, while the clamping cylinder 61 contracts, the tightening cylinder 64 extends, so that the pressing cylinder 62 is pulled out of the tightening hole 68, and the pressing cylinder 62 remains in the position of abutting against the planetary gear 11. A chamfer 69 is formed at the upper edge of the upper end of the tightening hole 68. Place the snap ring 14 at the chamfer 69 position of the tightening hole 68, then the clamping cylinder 61 drives the pressing cylinder 62 to move downward, and at the same time the tightening cylinder 64 contracts, keeping the tightening block 63 abutting against the planetary gear 11. The pressing cylinder 62 squeezes the snap ring 14 into the tightening hole 68, making the diameter of the snap ring 14 smaller. Then the snap ring 14 moves downward through the tightening hole 68 and enters the inner hole of the planetary gear 11 and is clamped in place. Then the clamping cylinder 61 contracts, and the tightening block 63 on the first slider 65 and the pressing cylinder 62 on the second slider 66 move upward.

[0053] Reference Figure 9, a moving device 7 for moving the snap ring 14 onto the tightening hole 68 is provided at the discharge end of the first vibrating bowl 22. The moving device 7 includes a stop block 71, a magnetic head 72, a horizontal cylinder 73, a vertical cylinder 74 and a plugging cylinder 75. The stop block 71 is horizontally slidably connected to the frame 3. A receiving groove 76 for receiving the snap ring 14 is formed on the upper surface of the stop block 71. The plugging cylinder 75 is fixed to the frame 3, and the output end of the plugging cylinder 75 is fixedly connected to the stop block 71, so that the plugging cylinder 75 can drive the stop block 71 to move horizontally. When the receiving groove 76 on the stop block 71 corresponds to the discharge end of the first vibrating bowl 22, one of the snap rings 14 on the first vibrating bowl 22 can enter the receiving groove 76. Then the plugging cylinder 75 drives the stop block 71 to move, so that the receiving groove 76 is misaligned with the discharge end of the first vibrating bowl 22, and at the same time, the side wall of the stop block 71 blocks the end of the first vibrating bowl 22. The horizontal cylinder 73 is fixed to the frame 3, and a vertical cylinder 74 is fixedly arranged at the output part of the horizontal cylinder 73. The vertical cylinder 74 is vertically arranged, and the magnetic head 72 is fixed to the output end of the vertical cylinder 74, so that the vertical cylinder 74 can drive the magnetic head 72 to move vertically. During use, the horizontal cylinder 73 first drives the magnetic head 72 to move directly above the receiving groove 76, and then the vertical cylinder 74 drives the magnetic head 72 to move downward into the receiving groove 76, so that one snap ring 14 is sucked onto the magnetic head 72. At the same time, by separating one snap ring 14 from the snap rings 14 on the first vibrating bowl 22, it can be ensured that the sucked snap ring 14 is single by the magnetic head 72. The magnetic head 72 is a hollow structure. The end of the horizontal cylinder 73 driving the magnetic head 72 to move is directly above the tightening hole 68. Then, under the action of the vertical cylinder 74, the magnetic head 72 is placed on the chamfer 69 at the upper end of the tightening hole 68. Then, the pressing cylinder 62 is inserted into the center position of the magnetic head 72 and the snap ring 14 is squeezed.

[0054] Reference Figure 10, a transition device 8 is provided on the frame 3. The transition device 8 is used to move the press-fitted circlip 14 and the planetary gear 11 of the bearing 13 to the clamping position of the robotic arm 31. The transition device 8 includes a first moving platform 81 and a second moving platform 82. A rotating chuck 83 is installed on the first moving platform 81. The rotating chuck 83 is connected to a flipping cylinder 84. The flipping cylinder 84 outputs rotation. The flipping cylinder 84 is connected to the first moving platform 81 through a lifting cylinder 85 provided on the first moving platform 81. When the first moving platform 81 moves, the lifting cylinder 85 moves along with the operation of the first moving platform 81. The flipping cylinder 84 is installed at the output end of the lifting cylinder 85, so that the lifting cylinder 85 drives the flipping cylinder 84 to move up and down. The output shaft of the flipping cylinder 84 is used to install the rotating chuck 83, and the rotating chuck 83 is used to clamp the planetary gear 11 on the positioning rod 44. In use, the first moving platform 81 first moves the rotating chuck 83 to one end close to the positioning rod 44, then the lifting cylinder 85 makes the rotating chuck 83 descend to the position of the planetary gear 11, and the rotating chuck 83 clamps the planetary gear 11. Then, the planetary gear 11 is taken off the positioning rod 44 from bottom to top by the lifting cylinder 85. Then, the first moving platform 81 moves the rotating chuck 83 in the direction of the second moving platform 82. At the same time, the rotating chuck 83 rotates 180 degrees, so that the side of the planetary gear 11 where the circlip 14 is installed faces downward. The output part of the second moving platform 82 is used to receive the planetary gear 11 clamped by the rotating chuck 83, and then the second moving platform 82 drives the planetary gear 11 to move to the clamping position of the robotic arm 31.

[0055] Embodiment 2:

[0056] This embodiment discloses a production device with a planetary gear reduction motor. Refer to Figure 11, different from the first embodiment in that: a bracket 9 is arranged inside the vertical cylinder 24. The bracket 9 includes an elastic C-shaped member 91 and a pull rod 92. The elastic C-shaped member 91 is fixedly connected to one end of the pull rod 92. A clamping groove 93 is arranged at the lower end of the vertical cylinder 24. The distance from the clamping groove 93 to the lower end face of the vertical cylinder 24 is less than the width of a bearing 13. The pull rod 92 is vertically arranged inside the vertical cylinder 24. An inclined surface 94 is formed at the side wall of the upper part of the clamping groove 93. The inclined surface 94 gradually slopes upward from the bottom of the clamping groove 93 to the opening of the clamping groove 93. When the C-shaped member 91 is pulled upward by the pull rod 92, the inclined surface 94 can squeeze the C-shaped member 91 to deform and shrink, so that the C-shaped member 91 can enter the vertical cylinder 24. An embedding groove 95 for placing the pull rod 92 is formed on the inner wall of the vertical cylinder 24 along the length direction of the vertical cylinder 24, so that the pull rod 92 can be located in the embedding groove 95, and the upper end of the pull rod 92 extends out of the vertical cylinder 24. When placing the bearing 13 into the vertical cylinder 24, first move the C-shaped member 91 to the upper end of the vertical cylinder 24 through the pull rod 92, then stack multiple bearings 13 vertically on the C-shaped member 91, and then gradually place the bearings 13 into the lower end of the vertical cylinder 24 through the pull rod 92, reducing the state that the bearings 13 become vertical when falling from the upper end of the vertical cylinder 24.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
