Description

Technical Field

[0001] The present invention relates to the technical field of bearing production, and specifically relates to a bearing assembly production device. Background Art

[0002] Bearing production refers to the process of manufacturing bearings. Bearings are important mechanical parts used to reduce friction between rotating parts in mechanical devices. In industrial production, especially in fields such as automobile manufacturing and machinery manufacturing, large-scale production of bearing components is required. A bearing production and assembly device can automate the production process of bearing components, improving production efficiency and consistency.

[0003] For example, a Chinese patent with the publication number CN211889780U discloses an assembly device for bearing production, which includes a machine body, a workbench, and a guide rod. The workbench is connected to the upper end of the machine body by bolts, and the guide rod is inserted through the middle of the workbench. The bottom end of the guide rod is connected to an electric push rod I by bolts, and the electric push rod I is installed in the machine body by bolts. By setting the electric push rod I and the guide rod, the bearing can be guided and positioned, ensuring accurate bearing assembly accuracy, ensuring bearing processing quality, and reducing bearing production and assembly costs. By setting the retaining edge, bearing groove, and travel plate, the bearing can be blocked and limited, ensuring accurate transmission of the bearing to the processing position, ensuring stable bearing transmission, and improving bearing assembly quality.

[0004] However, the above-mentioned bearing production and assembly device can only clamp the bearing, but cannot automatically carry out continuous assembly production after clamping, so there is no automatic connection between the clamping and assembly links, resulting in waiting time. Workers need to first centrally transport a batch of clamped bearings to the assembly area and then assemble them one by one. The handling and waiting processes in between will cause time waste and reduce production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a bearing assembly production device to solve the problem in the above-mentioned background art that it can only clamp the bearing but cannot automatically assemble it after clamping.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A bearing assembly production device includes: a connecting frame, with drive columns rotatably installed at both ends of the connecting frame. Two conveyor belts are sleeved on the outer surfaces of the two drive columns. The conveyor belts can convey the outer and inner rings of the bearings to be assembled. One of the drive columns is fixedly connected to the output shaft of a first motor, and the first motor is fixedly installed at one end of the connecting frame. The distance between the two conveyor belts allows a pushing mechanism to pass through and push the inner ring towards the annular opening end of the outer ring, so as to expand the distance between the outer and inner rings for the balls to be filled in. After the filling of the steel columns is completed, the pushing mechanism can be reset to push the inner ring back to the center of the inner ring of the outer ring to fit the balls inside. The pushing mechanism is fixedly installed on the upper surface of a bracket, and the bracket is fixedly installed at the lower end between the connecting frames;

[0008] Among them, a support frame is fixedly installed on the upper surface of the connecting frame, a mounting plate is fixedly installed on the upper surface of the support frame, a feeding mechanism is fixedly installed on the upper surface of the mounting plate, and the feeding mechanism stores balls, enabling it to supply a set number of balls according to the set filling value and fill them between the outer and inner rings;

[0009] Among them, a clamping mechanism is fixedly installed at the middle section of the upper surface of the bracket. The clamping end of the clamping mechanism passes through one end of the conveyor belt and slides on the surfaces of the two conveyor belts, so as to clamp the conveyed outer ring inside. The inner ring is limited inside by the outer ring and will be pushed by the pushing mechanism against the inner ring wall of the outer ring, making the expanded distance between the outer and inner rings flush with the discharge port of the feeding mechanism.

[0010] Preferably, two guide plates are fixedly installed at one end of the support frame. The two guide plates are arranged oppositely and form an eight-shaped shape and slide on the surfaces of the two conveyor belts, so that the outer ring can be slid towards the center by the two guide plates during the process of being conveyed by the conveyor belt, for the clamping mechanism to accurately clamp it.

[0011] Preferably, the feeding mechanism includes a storage cylinder, which is fixedly installed on the upper surface of the mounting plate. The lower surface of the storage cylinder is connected and installed with a discharge pipe, and the discharge pipe penetrates through the upper surface of the mounting plate and is connected and communicated with a docking plate. The docking plate is fixedly installed at one end of the mounting plate. A feeding disk is rotatably installed in the docking plate. Four inner embedding grooves are equidistantly arranged on the outer surface of the feeding disk, so that the feeding disk can drive the inner embedding grooves to be flush with the discharge pipe through rotation, allowing the balls stored in the storage cylinder to fall into the inner embedding grooves of the feeding disk through the discharge pipe. The balls falling into the inner embedding grooves can be driven to be flush with the feeding pipe through the rotation of the feeding disk, and then the balls can fall out of the inner embedding grooves into the feeding pipe and be discharged. The feeding pipe is connected and installed on the lower surface of the docking plate.

[0012] Preferably, the feeding tray is fixedly connected to the output shaft of the second motor. The second motor is fixedly installed at one end of the docking tray. Rotation grooves are formed at both ends inside the docking tray. A connecting tray is rotatably installed in the rotation grooves. The connecting tray is fixedly installed at both ends of the feeding tray. A dial is fixedly installed on the outer surface of the feeding tray. The dial can push the vibrating elastic piece during the process of being driven by the feeding tray to rotate. The vibrating elastic piece is fixedly installed in a ring shape on the inner ring wall of the rotation groove. In this way, during the process of the feeding tray being driven to rotate, the vibrating elastic piece can be pushed by the dial to generate a vibration force, so as to realize the function of vibrating feeding.

[0013] Preferably, a first photoelectric sensor is installed in the feeding pipe in a communicating manner, so that when the ball bearings fall out of the feeding pipe, they will be detected by the first photoelectric sensor and counted. The signal transmitting end of the first photoelectric sensor is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electric control ends of the first motor and the second motor.

[0014] Preferably, the clamping mechanism includes a double-shaft motor, and the double-shaft motor is also controlled by the controller. The double-shaft motor is fixedly installed on the upper surface of the bracket. First bevel gears are fixedly installed on the output shafts at both ends of the double-shaft motor. The two first bevel gears are respectively meshed with second bevel gears. The second bevel gears are rotatably installed on the upper surface of the triangular bracket. The triangular bracket is fixedly installed on the upper surface of the bracket. A gear is fixedly installed on the upper surface of the second bevel gear. The gear is meshed with a rack. The rack is fixedly installed in an embedded manner at one end of the guide rod. The guide rod is slidably installed in the guide frame. The guide frame is fixedly installed on the upper surface of the connecting frame. Inner arc clips are fixedly installed at the inner ends of the two guide rods.

[0015] Preferably, the two arc clips can drive the two guide rods to slide synchronously inward or outward in the two guide frames through the gears meshing with the gears driven by the double-shaft motor, so as to clamp the outer ring of the bearing inside.

[0016] Preferably, a second photoelectric sensor is fixedly installed in an embedded manner on the inner arc surface of one of the arc clips. The second photoelectric sensor can detect that the outer ring of the bearing is conveyed in front by the conveyor belt. The signal transmitting end of the second photoelectric sensor is connected to the signal receiving end of the controller;

[0017] Among them, the models of the first photoelectric sensor, the second photoelectric sensor and the controller are E3Z-LT61, EX-304 and S7-200SMART respectively.

[0018] Preferably, the pushing mechanism includes an inclined slide plate and a connecting plate. An inclined slide opening is formed in the connecting plate, so that the connecting plate can be slidably installed on the outer surface of the inclined slide plate through the inclined slide opening. The inclined slide plate is fixedly installed on the upper surface of the bracket. One end of the upper surface of the connecting plate is fixedly installed with a pushing plate. In this way, when the pushing plate slides on the outer surface of the inclined slide plate through the inclined slide opening, it will rise obliquely together, and then the pushing plate that moves horizontally and rises can slide out from between the two conveyor belts and slide into the inner ring of the bearing and push.

[0019] Preferably, a docking plate is fixedly installed on the lower surface of the connecting plate. The docking plate slides out from the upper surface of the bracket to the lower surface and is rotatably connected to the piston rod of the electric push rod. The other end of the electric push rod is rotatably installed on the lower surface of the bracket. The electric control end of the electric push rod is also controlled by the controller.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Through the design of the conveyor belt, guide plates, first motor, feeding mechanism, clamping mechanism and pushing mechanism, during use, this conveyor belt can be docked with the equipment for producing bearing rings, so that the outer ring of the bearing can be sleeved on the outer surface of the inner ring and conveyed into the two groups of guide plates by the conveyor belt. The two groups of guide plates apply a function of sliding and pushing the conveyed bearing rings towards the center, so that when the bearing rings are conveyed out of the guide plates by the conveyor belt, they will be at the exact center of the two conveyor belts. Subsequently, with the continuous conveyance of the conveyor belt, the outer ring of the bearing can be aligned with the clamping mechanism and detected, enabling the clamping mechanism to send a signal to the controller to sequentially start the clamping mechanism, pushing mechanism and feeding mechanism, and at the same time shut down the first motor to stop the conveyance of the conveyor belt. The first-started clamping mechanism can then slide towards the center synchronously on the surfaces of the two conveyor belts to clamp the outer ring of the bearing inside, and through the synchronous pushing of the clamping mechanism, it can ensure that the outer ring is precisely at the exact center of the conveyor belt and is aligned with the feeding mechanism at the same time. The inner ring is then limited inside by the outer ring and will be slid up and inserted into the ring opening of the inner ring from the spacing between the two conveyor belts by the subsequently started pushing mechanism. With the continuous start of the pushing mechanism, the rising pushing mechanism can push the inner ring towards one end of the ring opening of the outer ring, so that the spacing pushed open between the outer ring and the inner ring is aligned with the discharge port of the feeding mechanism. Thus, the last-started feeding mechanism can fill the balls into the space between the outer ring and the inner ring. After the filling of the balls is completed, the pushing mechanism can be reset to push the inner ring back to the center of the inner ring of the outer ring to fit the balls inside, which completes the assembly production process of the bearing. Subsequently, the clamping mechanism can slide outwards synchronously to release the clamping of the outer ring. Then, the controller can restart the first motor to convey the assembled bearing away, and the unassembled outer ring can be clamped inside by the clamping mechanism again for assembly, realizing the full-process automation of "detection → clamping → pushing → filling → resetting", reducing manual intervention, increasing the production rhythm and reducing the assembly time of a single bearing.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1 - 4 shown, this embodiment provides a bearing assembly production device, including: a connecting frame 1, both ends of the connecting frame 1 are rotatably installed with transmission columns 101, the outer surfaces of the two groups of transmission columns 101 are sleeved with two groups of conveyor belts 102, the conveyor belts 102 can convey the outer rings and inner rings of the bearings to be assembled, and one of the transmission columns 101 is fixedly connected to the output shaft of the first motor 106, the first motor 106 is fixedly installed at one end of the connecting frame 1, and within the distance between the two groups of conveyor belts 102, the pushing mechanism 4 can pass through and push the inner ring close to one end of the ring opening of the outer ring, so as to expand the distance between the outer ring and the inner ring for the balls to be filled in. After the filling of the steel columns is completed, the pushing mechanism 4 can be reset to push the inner ring back to the center of the inner ring of the outer ring to fit the balls inside, and the pushing mechanism 4 is fixedly installed on the upper surface of the bracket 107, and the bracket 107 is fixedly installed at the lower end between the connecting frames 1;

[0033] Among them, a support frame 103 is fixedly installed on the upper surface of the connecting frame 1, a mounting plate 105 is fixedly installed on the upper surface of the support frame 103, a feeding mechanism 2 is fixedly installed on the upper surface of the mounting plate 105, and the feeding mechanism 2 stores ball bearings, enabling it to supply and fill a set number of ball bearings according to the set filling value into the space between the outer ring and the inner ring;

[0034] Among them, a clamping mechanism 3 is fixedly installed at the middle section of the upper surface of the bracket 107. The clamping end of the clamping mechanism 3 rotates out from one end of the conveyor belt 102 and slides on the surfaces of the two conveyor belts 102, so as to clamp the conveyed outer ring inside. The inner ring is limited inside by the outer ring and will be pushed by the pushing mechanism 4 against the inner ring wall of the outer ring, so that the distance pushed open between the outer ring and the inner ring is flush with the discharge port of the feeding mechanism 2.

[0035] Two guide plates 104 are fixedly installed at one end of the support frame 103. The two guide plates 104 are arranged oppositely and form an inverted V shape, sliding on the surfaces of the two conveyor belts 102. In this way, during the process of the outer ring being conveyed by the conveyor belt 102, it can be slid towards the center by the two guide plates 104, so that the clamping mechanism 3 can accurately clamp it.

[0036] Through the design of the conveyor belt 102, the guide plates 104, the first motor 106, the feeding mechanism 2, the clamping mechanism 3 and the pushing mechanism 4, during use, this conveyor belt 102 can be docked with the equipment for producing bearing rings, so that the outer ring of the bearing is sleeved on the outer surface of the inner ring and is conveyed into the two groups of guide plates 104 by the conveyor belt 102. The two groups of guide plates 104 apply a function of sliding and pushing the conveyed bearing rings towards the center. As a result, when the bearing rings are conveyed out of the guide plates 104 by the conveyor belt 102, they will be at the exact center of the two conveyor belts 102. Subsequently, with the continuous conveyance of the conveyor belt 102, the outer ring of the bearing can be aligned with the clamping mechanism 3 and detected. Then, the clamping mechanism 3 can send a signal to the controller to cause the controller to sequentially start the clamping mechanism 3, the pushing mechanism 4 and the feeding mechanism 2, and at the same time turn off the first motor 106 to stop the conveyance of the conveyor belt 102. The initially started clamping mechanism 3 can then slide towards the center synchronously on the surfaces of the two conveyor belts 102 to clamp the outer ring of the bearing inside, and through the synchronous pushing of the clamping mechanism 3, it can ensure that the outer ring is precisely at the exact center of the conveyor belt 102 and is also aligned with the feeding mechanism 2 at the same time. The inner ring is then limited inside by the outer ring and is lifted and slid into the ring opening of the inner ring from the gap between the two conveyor belts 102 by the subsequently started pushing mechanism 4. With the continuous start of the pushing mechanism 4, the rising pushing mechanism 4 can push the inner ring towards one end of the ring opening of the outer ring together, so that the gap pushed open between the outer ring and the inner ring is aligned with the discharge port of the feeding mechanism 2. Then, the finally started feeding mechanism 2 can fill the balls into the space between the outer ring and the inner ring. After the filling of the balls is completed, the pushing mechanism 4 can be reset to push the inner ring back to the center of the inner ring of the outer ring to fit the balls inside, that is, the assembly production process of the bearing is completed. Subsequently, the clamping mechanism 3 can expand outward synchronously to release the clamping of the outer ring. Then, the controller can restart the first motor 106 to convey the assembled bearing away, and the unassembled outer ring can be clamped inside by the clamping mechanism again for assembly, thus realizing the full-process automation of "detection → clamping → pushing → filling → resetting", reducing manual intervention, increasing the production rhythm, and reducing the assembly time of a single bearing.

[0037] Such as Figures 5 - 6As shown, the feeding mechanism 2 includes a storage cylinder 201. The storage cylinder 201 is fixedly installed on the upper surface of the mounting plate 105. The lower surface of the storage cylinder 201 is connected and installed with a discharge pipe 202. The discharge pipe 202 penetrates through the upper surface of the mounting plate 105 and is connected and communicated with a docking plate 205. The docking plate 205 is fixedly installed at one end of the mounting plate 105. A feeding plate 211 is rotatably installed in the docking plate 205. Four groups of embedded grooves are equidistantly arranged on the outer surface of the feeding plate 211, so that the feeding plate 211 can drive the embedded grooves to be flush with the discharge pipe 202 through rotation, enabling the balls stored in the storage cylinder 201 to fall into the embedded grooves of the feeding plate 211 through the discharge pipe 202. The balls falling into the embedded grooves can be driven by the rotation of the feeding plate 211 to be flush with the feeding pipe 204, and then the balls can fall from the embedded grooves into the feeding pipe 204 and be discharged. The feeding pipe 204 is connected and installed on the lower surface of the docking plate 205.

[0038] The feeding plate 211 is fixedly connected to the output shaft of the second motor 206. The second motor 206 is fixedly installed at one end of the docking plate 205. Rotating grooves 207 are opened at both ends inside the docking plate 205. A connecting plate 209 is rotatably installed in the rotating grooves 207. The connecting plate 209 is fixedly installed at both ends of the feeding plate 211. A dial 210 is fixedly installed on the outer surface of the feeding plate 211. The dial 210 can push the vibration elastic piece 208 during the process of being driven to rotate by the feeding plate 211. The vibration elastic piece 208 is fixedly installed in a ring shape on the inner ring wall of the rotating groove 207, so that the feeding plate 211 can generate a vibration force by pushing the vibration elastic piece 208 through the dial 210 during the process of being driven to rotate, to realize the function of vibrating feeding.

[0039] A first photoelectric sensor 203 is connected and installed inside the feeding pipe 204, so that when the balls fall out of the feeding pipe 204, they will be detected by the first photoelectric sensor 203 and counted. The signal transmitting end of the first photoelectric sensor 203 is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electric control ends of the first motor 106 and the second motor 206.

[0040] Through the design of the storage cylinder 201, the discharge pipe 202, the first photoelectric sensor 203, the feeding tray 211, the paddle 210, the second motor 206, and the vibration shrapnel 208, after the outer ring of the bearing is clamped by the clamping mechanism 3 and the inner ring is pushed and clamped against one end of the ring opening of the outer ring, the second motor 206 can be started to drive the feeding tray 211 to rotate. The four sets of embedded grooves on the outer surface of the feeding tray 211 are aligned with the discharge pipe 202 in sequence as it rotates, allowing the ball bearings in the storage cylinder 201 to fall into the embedded grooves through the discharge pipe 202 under the action of gravity. Each embedded groove can only accommodate a single ball bearing, ensuring the quantitative nature of single feeding. During the rotation of the feeding tray 211, the paddle 210 on the outer surface of its connecting plate 209 will push against the vibration shrapnel 208 on the inner wall of the rotating groove 207. After being squeezed, the vibration shrapnel 208 rebounds to generate high-frequency vibration, which is transmitted to the feeding tray 211 through the connecting plate 209. This vibration can prevent the ball bearings from sticking or getting stuck and remaining in the embedded grooves, ensuring that the ball bearings smoothly slide into the feeding pipe 204, thereby improving the reliability of material feeding. As the feeding tray 211 drives the embedded grooves to rotate until they are flush with the feeding pipe 204, the ball bearings in the embedded grooves can fall into the feeding pipe 204 and drop between the outer ring and the inner ring. When each group of ball bearings falls out through the feeding pipe 204, they will pass through the first photoelectric sensor 203 in sequence. The first photoelectric sensor 203 generates a change in the electrical signal by detecting the occlusion of the light path by the ball bearings. Each time a ball bearing is detected, a counting pulse is sent to the controller. When the count value reaches the preset total filling number, the controller will immediately send a stop instruction to the second motor 206 to stop the rotation of the feeding tray 211, avoiding overfilling of the ball bearings and ensuring that the number of ball bearings in each bearing strictly meets the design requirements, further improving the accuracy and quality stability of the product.

[0041] As Figure 7 shown, the clamping mechanism 3 includes a biaxial motor 301, which is also controlled by the controller. The biaxial motor 301 is fixedly installed on the upper surface of the bracket 107. First bevel gears 302 are fixedly installed on the output shafts at both ends of the biaxial motor 301. The two sets of first bevel gears 302 are respectively engaged with second bevel gears 304. The second bevel gears 304 are rotatably installed on the upper surface of the tripod 303. The tripod 303 is fixedly installed on the upper surface of the bracket 107. A gear 305 is fixedly installed on the upper surface of the second bevel gear 304. The gear 305 is engaged with a rack 307. The rack 307 is fixedly installed in an embedded manner at one end of a guide rod 306. The guide rod 306 is slidably installed in a guide frame 308. The guide frame 308 is fixedly installed on the upper surface of the connecting frame 1. Inner ends of the two sets of guide rods 306 are both fixedly installed with arc-shaped clamps 309.

[0042] The two sets of arc clamps 309 can drive the two sets of guide rods 306 to slide synchronously inward or outward in the two sets of guide frames 308 through the gears 305 meshed by the rack 307 driven by the dual-axis motor 301, so as to clamp the outer ring of the bearing inside.

[0043] On the inner arc surface of one of the sets of arc clamps 309, a second photoelectric sensor 310 is fixedly installed in an embedded manner. The second photoelectric sensor 310 can detect that the outer ring of the bearing is conveyed in front by the conveyor belt 102. The signal transmitting end of the second photoelectric sensor 310 is connected to the signal receiving end of the controller;

[0044] Among them, the models of the first photoelectric sensor 203, the second photoelectric sensor 310, and the controller are E3Z-LT61, EX-304, and S7-200SMART respectively.

[0045] Through the design of the dual-axis motor 301, the first bevel gear 302, the second bevel gear 304, the gear 305, the guide rod 306, the arc clamp 309, and the second photoelectric sensor 310, the outer ring that is pushed and slid towards the center through the guide plate 104, as the conveyor belt 102 continues to convey, can make the outer ring of the bearing flush with the second photoelectric sensor 310 in the arc clamp 309 and be detected. The second photoelectric sensor 310 can detect that the outer ring of the bearing is conveyed in front by the conveyor belt 102. Its signal transmitting end sends a signal to the controller. After receiving the signal, the controller analyzes and processes the signal. After identifying that this is a signal that the outer ring of the bearing has reached the specified position, it will start the dual-axis motor 301 to drive the first bevel gears 302 fixedly installed on the two output shafts to rotate synchronously. Furthermore, it can make the first bevel gear 302 mesh and drive the second bevel gear 304 to rotate on the upper surface of the tripod 303, and the second bevel gear 304 can drive the gear 305 fixedly installed on the upper surface to mesh and drive the rack 307 to drive the two sets of guide rods 306 to slide synchronously towards the center in the guide frame 308. Furthermore, it can make the two sets of guide rods 306 drive the arc clamps 309 at the inner ends to slide inward synchronously with the guide rods 306 and gradually approach the outer ring of the bearing. Finally, the two sets of arc clamps 309 tightly clamp the outer ring of the bearing inside, ensuring that the outer ring maintains a stable position in the subsequent assembly process. And through the synchronous sliding of the two sets of arc clamps 309, it can ensure that the outer ring is pushed to the center of the two conveyor belts 102 and clamped, and further can ensure that the outer ring is in a stable and centered position in the subsequent assembly process. In this way, when the inner ring and the outer ring are fitted and the balls are filled, the relative positions of the components are more accurate, thereby reducing the assembly error caused by the position deviation of the outer ring and improving the overall assembly accuracy and quality of the bearing.

[0046] Such as Figure 8As shown, the pushing mechanism 4 includes an inclined slide plate 401 and a connecting plate 404. An inclined slide opening 405 is formed in the connecting plate 404, enabling the connecting plate 404 to be slidably mounted on the outer surface of the inclined slide plate 401 through the inclined slide opening 405. The inclined slide plate 401 is fixedly mounted on the upper surface of the bracket 107. One end of the upper surface of the connecting plate 404 is fixedly mounted with a pushing plate 406. In this way, when the pushing plate 406 slides on the outer surface of the inclined slide plate 401 through the inclined slide opening 405, it will rise obliquely together, and then the pushing plate 406 that moves horizontally and rises can slide out from between the two conveyor belts 102 and slide into the inner ring of the bearing and push.

[0047] A docking plate 403 is fixedly mounted on the lower surface of the connecting plate 404. The docking plate 403 slides out from the upper surface of the bracket 107 to the lower surface and is rotatably connected to the piston rod of the electric push rod 402. The other end of the electric push rod 402 is rotatably mounted on the lower surface of the bracket 107. The electric control end of the electric push rod 402 is also controlled by the controller.

[0048] Through the design of the inclined slide plate 401, the electric push rod 402, the docking plate 403, the connecting plate 404, the inclined slide opening 405 and the pushing plate 406, after the outer ring is clamped between the two arc clamps 309, the electric push rod 402 can be started to pull the docking plate 403 through the piston rod, and the docking plate 403 can then pull the connecting plate 404 to slide obliquely upward on the outer surface of the inclined slide plate 401. Then, the pushing plate 406 that rises obliquely can slide out from between the two conveyor belts 102 and slide into the inner ring of the bearing. Subsequently, as the pushing plate 406 is continuously pulled, the pushing plate 406 can push the inner ring closer to the ring opening of the outer ring, so that the other end of the inner ring and the outer ring is gradually expanded until the distance is flush with the discharge port of the discharge pipe 202, creating space for ball filling. After the ball filling is completed, the electric push rod 402 can push the docking plate 403 to drive the connecting plate 404 to descend obliquely on the outer surface of the inclined slide plate 401. Then, the connecting plate 404 can drive the pushing plate 406 fixedly mounted on the upper surface to push the inner ring back to the central part of the outer ring, so that the internally filled balls are fitted in the raceways between the outer ring and the inner ring, avoiding ball deviation or loosening. Subsequently, the pushing plate 406 can be continuously pushed to slide out from the lower end of the ring opening of the inner ring and slide back into between the two conveyor belts 102. Thus, the entire process from "pushing the inner ring → ball filling → inner ring reset → mechanism withdrawal" is coordinated by the controller uniformly, and each action is seamlessly connected, reducing idling or waiting time, improving the single-bearing assembly efficiency, and ensuring the continuous operation of the production line.

[0049] Among them, in order to solve the problem of vibration anti-sticking in the quantitative conveying of balls during the bearing assembly process, the controller is configured with a dynamic vibration transfer efficiency equation module for optimizing vibration parameters. The dynamic vibration transfer efficiency equation is as follows:

[0050]

[0051] Wherein:

[0052] Η v is the ball detachment efficiency coefficient (dimensionless), and a threshold value η v ≥0.85 is set;

[0053] w is the real-time rotational speed (rad / s) of the second motor 206;

[0054] A is the amplitude (mm) of the vibration leaf spring 208, measured by a laser displacement sensor;

[0055] μ is the friction coefficient between the ball and the inner groove wall, with a value range of 0.1 - 0.3;

[0056] t c is the contact time (ms) between the single paddle 210 and the vibration leaf spring 208;

[0057] τ is the stress relaxation time (ms) of the vibration leaf spring material. For a steel leaf spring, it is 6 - 10 ms, and for an engineering plastic leaf spring, it is 15 - 20 ms;

[0058] N is the number of inner grooves on the feeding tray 211 that simultaneously carry the balls, detected by a Hall sensor;

[0059] w c is the critical rotational speed (rad / s), calculated from the structural stiffness of the feeding tray 211;

[0060] The controller dynamically adjusts the rotational speed of the second motor 206 according to the η v value calculated in real time. When it detects that η v <0.8, it triggers the feeding tray 211 to rotate reversely by 5° - 10° to eliminate ball jamming.

[0061] The working principle process of this scheme:

[0062] 1. Dynamic matching stage:

[0063] The controller monitors the N value in real time (through the inner groove position sensor);

[0064] Dynamically adjusts w according to the current material parameters μ, τ to maximize η v ;

[0065] When it detects that η is continuously less than 0.8 three times v it triggers the self-cleaning program;

[0066] 2. Vibration energy transfer:

[0067] The shock wave generated by the paddle impact propagates in the leaf spring;

[0068] A in the equation 2 The term reflects the stress wave superposition effect;

[0069] The non - linear exponential term reflects the material damping characteristics;

[0070] 3. Optimization of the detachment process:

[0071] High η v value corresponds to the ball obtaining sufficient kinetic energy to overcome static friction;

[0072] The vibration frequency spectrum is controlled within the optimal range of 50 - 150 Hz through Fourier analysis;

[0073] Set the safety boundary w ≤ 0.75w c to prevent structural fatigue.

[0074] Experimental data shows that after applying this equation:

[0075] The single - bearing assembly time is shortened by 23% (from 5.2 s to 4.0 s)

[0076] The ball jamming rate drops from 1.8% to 0.25%

[0077] The energy consumption is reduced by 18% (optimizing vibration parameters to reduce ineffective vibration).

[0078] This scheme couples the material dynamic characteristics with kinematic parameters, breaks through the limitation of traditional vibration feeding relying on empirical parameter adjustment, realizes adaptive control based on physical models, and provides a new theoretical tool for precision assembly equipment.

[0079] Summarize and sort out the working steps of this solution according to the above technical solution: When in use, the conveyor belt 102 can be docked with the equipment for producing bearing rings, so that the outer ring of the bearing is sleeved on the outer surface of the inner ring and is conveyed into the two guide plates 104 by the conveyor belt 102. The two guide plates 104 apply a function of sliding and pushing the conveyed bearing rings towards the center, so that the bearing rings will be at the exact center of the two conveyor belts 102 when they are conveyed out of the guide plates 104 by the conveyor belt 102. Subsequently, with the continuous conveyance of the conveyor belt 102, the outer ring of the bearing can be flush with the second photoelectric sensor 310 in the arc clamp 309 and be detected. The second photoelectric sensor 310 can detect that the outer ring of the bearing is conveyed in front of it, and its signal transmitting end sends the signal to the controller. After receiving the signal, the controller analyzes and processes the signal. After identifying that this is the signal that the outer ring of the bearing has reached the specified position, after receiving the signal, the controller first stops the first motor 106 to turn off the conveyance of the conveyor belt 102, and then starts the double-shaft motor 301, the electric push rod 402 and the second motor 206 in sequence. The first started double-shaft motor 301 can drive the first bevel gears 302 fixedly installed on the output shafts at both ends to rotate synchronously, so that the first bevel gears 302 can meshingly drive the second bevel gears 304 to rotate on the upper surface of the tripod 303. The second bevel gears 304 can drive the gears 305 fixedly installed on the upper surface to meshingly drive the rack 307 to drive the two guide rods 306 to slide synchronously towards the center in the guide frame 308, so that the two guide rods 306 can drive the arc clamps 309 at the inner ends to slide inwards synchronously with the guide rods 306 and gradually approach the outer ring of the bearing. Finally, the two arc clamps 309 tightly clamp the outer ring of the bearing inside. Subsequently, the started electric push rod 402 can pull the docking plate 403 through the piston rod, and the docking plate 403 can pull the connecting plate 404 to slide obliquely upwards on the outer surface of the inclined slide plate 401, so that the obliquely rising push plate 406 can slide out from between the two conveyor belts 102 and slide into the inner ring of the bearing. Subsequently, with the continuous pulling of the push plate 406, the push plate 406 can push the inner ring towards the ring opening of the outer ring to gradually expand the other ends of the inner ring and the outer ring until the distance is flush with the discharge port of the discharge pipe 202, creating space for filling the balls. Finally, the started second motor 206 can drive the feed tray 211 to rotate, and the four embedded grooves on the outer surface of the feed tray 211 are aligned with the discharge pipe 202 in sequence with the rotation, so that the balls in the storage cylinder 201 fall into the embedded grooves through the discharge pipe 202 under the action of gravity. Each embedded groove only accommodates a single ball to ensure the quantitative feeding for each time. And during the rotation of the feed tray 211, the flapper 210 on the outer surface of its connecting plate 209 will push against the vibration elastic piece 208 on the inner wall of the rotating groove 207. After being squeezed, the vibration elastic piece 208 rebounds to generate high-frequency vibration and transmits it to the feed tray 211 through the connecting plate 209. This vibration can prevent the balls from sticking, jamming and staying in the embedded grooves.Ensure that the ball bearings smoothly slide into the feeding tube 204, thereby improving the reliability of material feeding. When the feeding tray 211 drives the embedded groove to rotate until it is flush with the feeding tube 204, the ball bearings in the embedded groove can fall into the feeding tube 204 and drop between the outer ring and the inner ring. And when each group of ball bearings drops out through the feeding tube 204, they will sequentially pass through the first photoelectric sensor 203. The first photoelectric sensor 203 generates a change in the electrical signal by detecting the occlusion of the light path by the ball bearings. Each time a ball bearing is detected, a counting pulse is sent to the controller. When the counted value reaches the preset total filling number, the controller will immediately send a stop instruction to the second motor 206 to stop the rotation of the feeding tray 211, avoiding overfilling of the ball bearings. After the filling of the ball bearings is completed, the electric push rod 402 can push the docking plate 403 to drive the connecting plate 404 to descend obliquely on the outer surface of the inclined slide plate 401. Thus, the connecting plate 404 can drive the pushing plate 406 fixedly installed on the upper surface to push the inner ring back to the central part of the outer ring, so that the internally filled ball bearings are fitted into the raceways between the outer ring and the inner ring, avoiding the deviation or loosening of the ball bearings. Subsequently, the pushing plate 406 can be continuously pushed to slide out from the lower end of the annular opening of the inner ring and slide into the space between the two conveyor belts 102. After this series of processes are completed, the controller can control the dual-axis motor 301 and the first motor 106 again. The dual-axis motor 301 can drive the arc clamp 309 to open to release the clamping of the outer ring. And the started first motor 106 can drive the assembled bearing to be conveyed away by the conveyor belt 102, and the unassembled outer ring is clamped again and the above-mentioned assembly operation is carried out again.

[0080] In summary: The fully automated assembly process of "detection → clamping → pushing → filling → reset" is realized. Each action is seamlessly connected, reducing the waiting time, improving the single-bearing assembly efficiency, and ensuring the continuous operation of the production line.
