Description

Technical Field

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

[0002] Bearing production refers to the process of manufacturing bearings, a critical mechanical component used to reduce friction between rotating parts in mechanical devices. Industrial production, particularly in the automotive and machinery manufacturing sectors, requires large-scale production of bearing assemblies. Bearing production assembly equipment can automate the production process of bearing assemblies, improving production efficiency and consistency.

[0003] For example, the Chinese patent with announcement number CN211889780U discloses an assembly device for bearing production, including a machine body, a workbench and a guide rod. The upper end of the machine body is connected to the workbench by bolts, the middle of the workbench is interspersed with a guide rod, the bottom end of the guide rod is connected to an electric push rod by bolts, and the electric push rod is installed in the machine body by bolts. By setting the electric push rod and the guide rod, the bearing can be guided and positioned to ensure the accuracy of the bearing assembly, ensure the bearing processing quality, and reduce the bearing production and assembly cost. By setting the retaining edge, bearing groove, and stroke plate, the bearing can be blocked and limited to ensure that the bearing is accurately transmitted to the processing position, ensure the stable transmission of the bearing, and improve the bearing assembly quality.

[0004] However, the above-mentioned assembly device for bearing production can only clamp the bearings, but cannot automatically and continuously assemble them after clamping. As a result, there is no automated connection between the clamping and assembly links, which leads to waiting time. Workers are required to first transport a batch of clamped bearings to the assembly area and then assemble them one by one. The transportation and waiting process in between will cause time waste and reduce production efficiency. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Through the design of the conveyor belt, guide plate, first motor, feeding mechanism, clamping mechanism and pushing mechanism, when in use, the conveyor belt can be connected to the equipment for producing bearing rings to allow the outer ring of the bearing to be sleeved on the outer surface of the inner ring and transported into the two sets of guide plates by the conveyor belt, and the two sets of guide plates apply a sliding push function toward the center to the conveyed bearing ring, so that the conveyor belt in the bearing ring can be transported out of the guide plate at the exact center of the two sets of conveyor belts. Subsequently, as the conveyor belt continues to transport, the outer ring of the bearing can be aligned with the clamping mechanism and detected, so that the clamping mechanism can send a signal to the controller to enable the controller to start the clamping mechanism, pushing mechanism and feeding mechanism in sequence, and at the same time turn off the first motor to stop the conveying of the conveyor belt. The clamping mechanism that is started first can slide synchronously toward the center on the surface of the two sets of conveyor belts to clamp the outer ring of the bearing inside, and the synchronous push of the clamping mechanism can ensure that the outer ring is accurately in the exact center of the conveyor belt and is aligned with the feeding mechanism at the same time. The inner ring is limited by the outer ring and will be lifted and slid into the ring opening of the inner ring by the pushing mechanism that is subsequently activated from the gap between the two sets of conveyor belts. As the pushing mechanism continues to start, the rising pushing mechanism can push the inner ring toward one end of the ring opening of the outer ring, so that the gap between the outer ring and the inner ring is flush with the discharge port of the feeding mechanism, so that the feeding mechanism that is activated last can fill the balls between the outer ring and the inner ring. After the balls are filled, 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, thus completing the assembly production process of the bearing. The clamping mechanism can then slide outward synchronously to release the clamping of the outer ring. The controller can then restart the first motor to transport the assembled bearing away, so that the unassembled outer ring is clamped inside by the clamping mechanism again for assembly, thus realizing the automation of the entire process of "detection → clamping → pushing → filling → reset", reducing manual intervention, improving production cycle, and reducing the assembly time of a single bearing.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 4 As shown, this embodiment provides a bearing assembly production device, including: a connecting frame 1, transmission columns 101 are rotatably installed at both ends of the connecting frame 1, and two groups of conveyor belts 102 are sleeved on the outer surfaces of the two groups of transmission columns 101. The conveyor belts 102 can convey the outer ring and inner ring of the bearing that need to be assembled, and one group of transmission columns 101 is fixedly connected to the output shaft of the first motor 106, and the first motor 106 is fixedly installed at one end of the connecting frame 1. The space between the two groups of conveyor belts 102 can allow the pushing mechanism 4 to pass through and push the inner ring toward one end of the ring mouth of the outer ring, so as to expand the space between the outer ring and the inner ring so that the ball can be filled in. After the steel column is filled, 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 ball inside. 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 frame 1;

[0033] The support frame 103 is fixedly mounted on the upper surface of the connecting frame 1, the mounting plate 105 is fixedly mounted on the upper surface of the supporting frame 103, and the feeding mechanism 2 is fixedly mounted on the upper surface of the mounting plate 105. The feeding mechanism 2 stores balls and can supply a set number of balls according to a set filling value and fill them between the outer ring and the inner ring;

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

[0035] Two sets of guide plates 104 are fixedly installed at one end of the support frame 103, and the two sets of guide plates 104 are arranged opposite to each other and form an eight-shaped sliding surface on the surface of the two sets of conveyor belts 102, so that the outer ring can be slid toward the center by the two sets of guide plates 104 during the process of being conveyed by the conveyor belt 102, so that the clamping mechanism 3 can accurately clamp it.

[0036] Through the design of the conveyor belt 102, the guide plate 104, the first motor 106, the feeding mechanism 2, the clamping mechanism 3 and the pushing mechanism 4, when in use, the conveyor belt 102 can be connected to the equipment for producing the bearing ring, so that the outer ring of the bearing can be sleeved on the outer surface of the inner ring and transported into the two sets of guide plates 104 by the conveyor belt 102. The two sets of guide plates 104 exert a sliding push function on the conveyed bearing ring toward the center, so that the conveyor belt 102 in the bearing ring can be transported out of the guide plate 104 at the exact center of the two sets of conveyor belts 102. Then, as the conveyor belt 102 continues to transport, the outer ring of the bearing can be aligned with the clamping mechanism 3 and detected, and then the clamping mechanism 3 can send a signal to the controller to enable the controller to start the clamping mechanism 3, the pushing mechanism 4 and the feeding mechanism 2 in sequence, and at the same time turn off the first motor 106 to stop the conveying of the conveyor belt 102, and the clamping mechanism 3 that is started first can slide synchronously toward the center on the surface of the two sets of conveyor belts 102 to clamp the outer ring of the bearing inside, and the synchronous pushing of the clamping mechanism 3 can ensure that the outer ring is accurately on the conveyor belt The inner ring is positioned in the center of the outer ring 102 and is flush with the feeding mechanism 2 at the same time, and the inner ring is limited by the outer ring and will be slid up from the gap between the two sets of conveyor belts 102 into the ring opening of the inner ring by the pushing mechanism 4 that is started later. As the pushing mechanism 4 is continuously started, the rising pushing mechanism 4 can push the inner ring toward one end of the ring opening of the outer ring, so that the gap between the outer ring and the inner ring pushed away is flush with the discharge port of the feeding mechanism 2, and then the feeding mechanism 2 that is started last can fill the balls between the outer ring and the inner ring, and after the balls are filled, 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 ball inside, thus completing the assembly production process of the bearing. The clamping mechanism 3 can then be synchronously slid outward to release the clamping of the outer ring. The controller can then restart the first motor 106 to allow the assembled bearing to be transported away, so that the unassembled outer ring is clamped inside by the clamping mechanism again for assembly, thus realizing the full process automation of "detection → clamping → pushing → filling → resetting", reducing manual intervention, improving production rhythm, and reducing the assembly time of a single bearing.

[0037] like Figure 5-Figure 6As shown, the feeding mechanism 2 includes a storage barrel 201, which is fixedly mounted on the upper surface of the mounting plate 105. A discharge pipe 202 is installed on the lower surface of the storage barrel 201. The discharge pipe 202 passes through the upper surface of the mounting plate 105 and is connected to the docking plate 205. The docking plate 205 is fixedly mounted on one end of the mounting plate 105. A feeding disc 211 is rotatably mounted in the docking disc 205. The outer surface of the feeding disc 211 is provided with four sets of embedded grooves at equal intervals. In this way, the feed tray 211 can drive the embedded groove to be flush with the discharge pipe 202 through rotation, and the balls stored in the storage barrel 201 can fall into the embedded groove of the feed tray 211 through the discharge pipe 202. The balls that fall into the embedded groove can be driven by the rotation of the feed tray 211 to be flush with the feed pipe 204, and then the balls can fall from the embedded groove into the feed pipe 204 and be discharged. The feed pipe 204 is connected and installed on the lower surface of the docking tray 205.

[0038] The feeding tray 211 is fixedly connected to the output shaft of the second motor 206, and the second motor 206 is fixedly installed at one end of the docking tray 205. Rotating grooves 207 are provided at both ends of the docking tray 205. A connecting disk 209 is rotatably installed in the rotating groove 207. The connecting disk 209 is fixedly installed at both ends of the feeding tray 211. A paddle 210 is fixedly installed on the outer surface of the feeding tray 211. The paddle 210 can push the vibrating shrapnel 208 during the rotation driven by the feeding tray 211. The vibrating shrapnel 208 is annular and fixedly installed on the inner ring wall of the rotating groove 207. In this way, the feeding tray 211 can be driven to rotate and the vibrating shrapnel 208 can be pushed by the paddle 210 to generate vibration force, thereby realizing the function of vibration blanking.

[0039] A first photoelectric sensor 203 is installed in the feeding tube 204, so that when the balls fall out of the feeding tube 204, they will be detected and counted by the first photoelectric sensor 203. 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 electrical control end of the first motor 106 and the second motor 206.

[0040] Through the design of the storage barrel 201, the discharge pipe 202, the first photoelectric sensor 203, the feeding tray 211, the paddle 210, the second motor 206 and the vibrating spring 208, the outer ring of the bearing is clamped inside by the clamping mechanism 3 and the inner ring is pushed and clamped to touch one end of the ring mouth of the outer ring, the second motor 206 can be started to drive the feeding tray 211 to rotate, and the four groups of embedded grooves on the outer surface of the feeding tray 211 are aligned with the discharge pipe 202 in sequence as they rotate, so that the balls in the storage barrel 201 fall into the embedded grooves through the discharge pipe 202 under the action of gravity, and each embedded groove only accommodates a single ball, ensuring the quantitative quality of a single feeding, and during the rotation of the feeding tray 211, the paddle 210 on the outer surface of its connecting disk 209 will push the vibrating spring 208 on the inner ring wall of the rotating groove 207, and the vibrating spring 208 rebounds after being squeezed to generate high-frequency vibration, which is transmitted to the feeding tray 2 through the connecting disk 209. 11. This vibration can prevent the balls from being stuck in the embedded groove due to adhesion and jamming, ensuring that the balls can slide smoothly into the feeding tube 204, thereby improving the reliability of material discharge. As the feeding tray 211 drives the embedded groove to rotate until it is flush with the feeding tube 204, the balls in the embedded groove can fall into the feeding tube 204 and fall between the outer ring and the inner ring. When each group of balls falls out through the feeding tube 204, it will pass through the first photoelectric sensor 203 in turn. The first photoelectric sensor 203 generates an electrical signal change by detecting the obstruction of the light path by the balls. Each time a ball is detected, a counting pulse is sent to the controller. When the count value reaches the preset total number of fillings, the controller will immediately send a stop command to the second motor 206 to stop the rotation of the feeding tray 211, avoiding excessive filling of balls and ensuring that the number of balls in each bearing strictly meets the design requirements, further improving the accuracy and quality stability of the product.

[0041] like Figure 7 As shown, the clamping mechanism 3 includes a dual-axis motor 301, which is also controlled by the controller. The dual-axis motor 301 is fixedly mounted on the upper surface of the bracket 107, and the output shafts at both ends of the dual-axis motor 301 are fixedly mounted with first bevel gears 302. The two sets of first bevel gears 302 are respectively meshed with the second bevel gears 304. The second bevel gear 304 is rotatably mounted on the upper surface of the tripod 303. The tripod 303 is fixedly mounted on the upper surface of the bracket 107. A gear 305 is fixedly mounted on the upper surface of the second bevel gear 304. The gear 305 is meshed with the rack 307. The rack 307 is fixedly mounted on one end of the guide rod 306 in an embedded manner. The guide rod 306 is slidably mounted in the guide frame 308. The guide frame 308 is fixedly mounted on the upper surface of the connecting frame 1, and the inner ends of the two sets of guide rods 306 are fixedly mounted with arc 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 gear 305 driven by the dual-axis motor 301 through the rack 307, thereby clamping the outer ring of the bearing inside.

[0043] A second photoelectric sensor 310 is fixedly installed on the inner arc surface of one set of arc clips 309 in an embedded manner. The second photoelectric sensor 310 can detect when the outer ring of the bearing is transported to the 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] 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 is pushed toward the center through the guide plate 104. As the conveyor belt 102 continues to convey, the outer ring of the bearing can be aligned with the second photoelectric sensor 310 in the arc clamp 309 and detected. The second photoelectric sensor 310 can detect that the outer ring of the bearing is conveyed to the front by the conveyor belt 102, and its signal transmitting end sends the signal to the controller. After receiving the signal, the controller analyzes and processes the signal, and recognizes 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 gear 302 fixed on the output shafts at both ends to rotate synchronously, thereby enabling the first bevel gear 302 to mesh with the second bevel gear 304 to rotate on the upper surface of the tripod 303, and the second bevel gear The wheel 304 can drive the gear 305 fixed on the upper surface to engage the transmission rack 307 to drive the two sets of guide rods 306 to slide synchronously toward the center in the guide frame 308, so that the two sets of guide rods 306 can drive the arc clamp 309 at the inner end to slide synchronously inward with the guide rod 306, gradually approaching 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 during 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 sets of conveyor belts 102 and clamped, thereby ensuring that the outer ring is in a stable and centered position during the subsequent assembly process. In this way, when the inner ring and the outer ring are matched and the balls are filled, the relative positions between the components are more accurate, thereby reducing the assembly error caused by the outer ring position deviation and improving the overall assembly accuracy and quality of the bearing.

[0046] like Figure 8As shown, the pushing mechanism 4 includes an inclined slide 401 and a connecting plate 404. An inclined sliding opening 405 is provided in the connecting plate 404, so that the connecting plate 404 can be slidably installed on the outer surface of the inclined slide 401 through the inclined sliding opening 405. The inclined slide 401 is fixedly installed on the upper surface of the bracket 107. A pushing plate 406 is fixedly installed on one end of the upper surface of the connecting plate 404, so that the pushing plate 406 can slide on the outer surface of the inclined slide 401 through the inclined sliding opening 405 and rise obliquely together, so that the pushing plate 406 that moves and rises can slide out from between the two sets of conveyor belts 102 and slide into the inner ring of the bearing and push.

[0047] A docking plate 403 is fixedly installed 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 installed 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 401, the electric push rod 402, the docking plate 403, the connecting plate 404, the inclined sliding mouth 405 and the pushing plate 406, after the outer ring is clamped by the two sets of 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 pull the connecting plate 404 to slide obliquely upward on the outer surface of the inclined slide 401, thereby allowing the obliquely rising pushing plate 406 to slide out from between the two sets of conveyor belts 102 and slide into the inner ring of the bearing. Then, as the pushing plate 406 is continuously pulled, the pushing plate 406 can push the inner ring closer to the ring mouth of the outer ring, so that the other end of the inner ring and the outer ring are gradually stretched apart until the distance is flush with the discharge port of the discharge pipe 202, for ball filling. To create space, after the balls are filled, 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 401, and then the connecting plate 404 can drive the pushing plate 406 fixedly installed on the upper surface to push the inner ring back to the center of the outer ring, so that the balls filled inside are embedded in the raceways of the outer and inner rings to prevent the balls from shifting or loosening. Subsequently, the pushing plate 406 can be continuously pushed to slide out from the lower end of the ring mouth of the inner ring and slide back between the two sets of conveyor belts 102, thereby realizing the whole process from "pushing the inner ring → ball filling → inner ring reset → mechanism withdrawal" coordinated by the controller, and each action is seamlessly connected, reducing idling or waiting time, improving the efficiency of single bearing assembly, and ensuring the continuous operation of the production line.

[0049] To solve the vibration anti-jamming problem of ball quantitative conveying during bearing assembly, the controller is equipped with a dynamic vibration transmission efficiency equation module to optimize vibration parameters. The dynamic vibration transmission efficiency equation is as follows:

[0050]

[0051] in:

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

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

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

[0055] μ is the friction coefficient between the ball and the inner groove wall, ranging from 0.1 to 0.3;

[0056] t c is the contact time between the paddle 210 and the vibrating spring 208 in a single stroke (ms);

[0057] τ is the stress relaxation time (ms) of the vibration shrapnel material. The stress relaxation time for steel shrapnel is 6-10ms, and the stress relaxation time for engineering plastic shrapnel is 15-20ms.

[0058] N is the number of embedded slots in the feeding tray 211 that simultaneously carry balls, detected by the Hall sensor;

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

[0060] The controller calculates η in real time. v The value dynamically adjusts the speed of the second motor 206, and when η is detected v When the angle is less than 0.8, the feeding tray 211 is triggered to rotate 5°-10° in the opposite direction to eliminate ball jamming.

[0061] The working principle of this program is as follows:

[0062] 1. Dynamic matching stage:

[0063] The controller monitors the N value in real time (via the built-in slot position sensor);

[0064] According to the current material parameters μ,τ, w is dynamically adjusted to make η v maximize;

[0065] When η is detected three times in a row v When <0.8, the self-cleaning program is triggered;

[0066] 2. Vibration energy transfer:

[0067] The impact of the paddle generates a shock wave that propagates through the shrapnel;

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

[0069] The nonlinear exponential term reflects the damping characteristics of the material;

[0070] 3. Disengagement process optimization:

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

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

[0073] Set the safety margin w≤0.75w c Prevent structural fatigue.

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

[0075] Single bearing assembly time reduced by 23% (from 5.2s to 4.0s)

[0076] Ball sticking rate reduced from 1.8% to 0.25%

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

[0078] This solution couples the dynamic characteristics of the material with the kinematic parameters, breaking through the limitations of traditional vibration feeding that relies on empirical parameter adjustment, realizing adaptive control based on physical models, and providing new theoretical tools for precision assembly equipment.

[0079] According to the above technical solution, the working steps of this solution are summarized and sorted out: when in use, the outer ring of the bearing can be put on the outer surface of the inner ring by connecting the conveyor belt 102 to the equipment for producing bearing rings, and the outer ring of the bearing can be transported into the two sets of guide plates 104 by the conveyor belt 102. The two sets of guide plates 104 exert a sliding function toward the center on the conveyed bearing ring, so that the conveyor belt 102 in the bearing ring can be transported out of the guide plate 104 and will be in the center of the two sets of conveyor belts 102. Subsequently, as the conveyor belt 102 continues to be transported, the outer ring of the bearing can be aligned with the second photoelectric sensor 310 in the arc clamp 309 and detected. The second photoelectric sensor 310 can detect that the outer ring of the bearing is transported to the front by the conveyor belt 102, and its signal transmitting end will The signal is sent to the controller, and after receiving the signal, the controller analyzes and processes the signal, and recognizes that this is a 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 stop the conveying of the conveyor belt 102, and then starts the dual-axis motor 301, the electric push rod 402 and the second motor 206 in sequence. The dual-axis motor 301 started first can drive the first bevel gear 302 fixedly installed on the output shafts at both ends to rotate synchronously, and then the first bevel gear 302 can be engaged with 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 fixed on the upper surface to engage the transmission rack 307 to drive the two sets of guide rods 306 to rotate synchronously on the guide frame 308. The two sets of arc clamps 309 will eventually clamp the outer ring of the bearing tightly inside, and the electric push rod 402 that is then started can pull the docking plate 403 through the piston rod, and the docking plate 403 can pull the connecting plate 404 to slide obliquely upward on the outer surface of the inclined slide plate 401, thereby allowing the obliquely rising pushing plate 406 to slide out from between the two sets of conveyor belts 102 and slide into the inner ring of the bearing. Then, as the pushing plate 406 is continuously pulled, the pushing plate 406 can push the inner ring close to the ring mouth of the outer ring, so that the other end of the inner ring and the outer ring is gradually stretched apart until the gap is formed. The distance is flush with the discharge port of the discharge pipe 202, creating space for the ball filling, and the second motor 206 that is started last can drive the feeding tray 211 to rotate, and the four groups of embedded grooves on the outer surface of the feeding tray 211 are aligned with the discharge pipe 202 in turn as they rotate, so that the balls in the storage barrel 201 fall into the embedded grooves through the discharge pipe 202 under the action of gravity. Each embedded groove only accommodates a single ball, ensuring the quantitative quality of a single feeding, and during the rotation of the feeding tray 211, the paddle 210 on the outer surface of its connecting disk 209 will push the vibrating spring piece 208 on the inner ring wall of the rotating groove 207, and the vibrating spring piece 208 will rebound after being squeezed to generate high-frequency vibration, which is transmitted to the feeding tray 211 through the connecting disk 209. This vibration can prevent the balls from being stuck in the embedded grooves due to adhesion and jamming.The feeding tray 211 drives the inner groove to rotate to be flush with the feeding tube 204, so that the balls in the inner groove can fall into the feeding tube 204 and fall between the outer ring and the inner ring. When each group of balls falls out through the feeding tube 204, they will pass through the first photoelectric sensor 203 in turn. The first photoelectric sensor 203 generates an electrical signal change by detecting the obstruction of the light path by the balls. Each time a ball is detected, a counting pulse is sent to the controller. When the count value reaches the preset total number of fillings, the controller immediately sends a stop command to the second motor 206 to stop the feeding tray 211 from rotating, thereby avoiding excessive filling of the balls. After the balls are filled, the electric push rod 402 can push the docking plate 403 to drive The connecting plate 404 descends obliquely on the outer surface of the inclined slide 401, thereby enabling the connecting plate 404 to drive the pushing plate 406 fixed on the upper surface to push the inner ring back to the center of the outer ring, so that the balls filled inside are embedded in the raceways of the outer and inner rings to prevent the balls from deviating 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 between the two sets of conveyor belts 102. After this series of processes is completed, the controller can control the dual-axis motor 301 and the first motor 106 again, and the dual-axis motor 301 can drive the arc clamp 309 to open to release the clamping of the outer ring. The started first motor 106 can drive the assembled bearing to be transported away by the conveyor belt 102, so that the unassembled outer ring can be clamped again and the above-mentioned assembly operation can be carried out again.

[0080] In summary: the fully automated assembly process of "detection → clamping → pushing → filling → resetting" is realized, and each action is seamlessly connected, which reduces waiting time, improves the efficiency of single bearing assembly, and ensures the continuous operation of the production line.
