Description

Technical Field

[0001] This utility model belongs to the field of automated assembly technology, and specifically relates to a bearing outer ring feeding tower, which can realize the automatic conveying, detection, positioning and transfer of bearing outer rings, improve the level of production automation, reduce labor costs and ensure stable product quality. Background Technology

[0002] In traditional bearing assembly, the bearing loading process has long relied on manual operation, which has many drawbacks. First, manual loading is inefficient. Operators need to frequently place the bearing outer rings onto the assembly station, which is not only labor-intensive but also difficult to match with high-speed assembly lines, severely restricting the overall production efficiency. Second, the accuracy of manual operation is difficult to guarantee. Due to operator fatigue and negligence, problems such as incorrect bearing outer ring placement and inaccurate positioning are prone to occur, leading to decreased assembly quality and increased product defect rates. Furthermore, manual loading poses significant safety hazards. When working in conjunction with automated equipment, operators' hands and other body parts are prone to collisions with moving parts, causing personal injury accidents.

[0003] Existing Chinese invention patent CN103508200A discloses an automatic feeding device for bearing inner rings, including a frame conveyor belt, a circular column, an upper fixed block, a pusher plate, and a lower fixed plate. The upper and lower fixed blocks are fixed to the circular column, the feed plate is fixed to the upper fixed block, and the pusher plate is placed between the feed plate and the lower fixed plate. The pusher plate has a slotted hole, through which bolts are threaded onto a power head. Although this device achieves automatic feeding of bearing inner rings to a certain extent, avoiding material waste and saving costs, due to the limitations of its structural design, some manual assistance is still required. The degree of automation is not high, and the efficiency improvement is limited, which is not conducive to further improving production efficiency.

[0004] Existing Chinese invention patent CN103359482A relates to an automatic bearing feeding device, including a support platform and a straight rod for receiving and feeding bearings. The straight rod is arranged vertically and located above the support platform. A gap is provided between the bottom end of the straight rod and the support platform, the height of which is not less than the axial width of the bearing. A guide groove for storing the bearings to be fed is provided on the support platform located on one side of the straight rod. The bottom of the guide groove is inclined downwards, and the height of the bottom of the groove is lower than the height of the support platform. A bearing pressing seat is connected to the lower end of the guide groove. A pushing unit is provided on the support platform located on the other side of the straight rod for pushing the bearings to be fed toward one side of the guide groove. This device pushes the bearings into the guide groove through the pushing unit, and then rolls them into the bearing pressing seat, achieving a certain degree of automatic feeding. However, this device only has two sets of bearing rods for placing the bearings, resulting in a small material storage capacity. This leads to a short replenishment cycle, requiring frequent replenishment by operators, and it still cannot completely eliminate the dependence on manual labor. In continuous large-scale production, its low efficiency problem is particularly prominent.

[0005] Furthermore, existing bearing loading equipment generally suffers from problems such as complex structure, difficult maintenance, and poor adaptability. Many devices are only suitable for specific bearing models. When a bearing model needs to be changed, extensive adjustments and modifications to the equipment are required, making the operation cumbersome, time-consuming, and unable to meet diverse production needs. At the same time, these devices have weak detection capabilities, unable to automatically detect the front and back sides of the bearing outer ring, still requiring manual identification, further impacting the efficiency and accuracy of loading.

[0006] In summary, existing bearing loading equipment has shortcomings in terms of automation, efficiency, safety, adaptability, and testing capabilities, failing to meet the requirements of modern industrial production for efficient, stable, and safe bearing assembly. Therefore, developing a bearing outer ring loading tower that is simple in structure, rationally designed, easy to operate, low in cost, highly efficient, safe, reliable, and possesses good adaptability and testing functions has become a pressing technical problem for those skilled in the art.

Detailed Implementation

[0048] The following description, with reference to the accompanying drawings, illustrates several preferred embodiments of the present invention to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0049] In the accompanying drawings, components with the same structure are indicated by the same numerical designation, and components with similar structures or functions are indicated by similar numerical designations. The dimensions and thicknesses of each component shown in the drawings are arbitrary, and this invention does not limit the dimensions and thicknesses of each component. To make the illustrations clearer, the thickness of some components has been appropriately exaggerated in the drawings.

[0050] like Figures 1-4 As shown, this embodiment provides a bearing outer ring feeding tower, including an equipment protective cover 1, a material rack turret 2, a bearing turntable 3, a camera detection mechanism 4, a bearing anti-lifting mechanism 5, and a barcode scanner 6;

[0051] The equipment protective cover 1 covers the material rack turret 2 and bearing turntable 3 to protect operators from injury from moving parts, and at the same time prevent foreign objects from entering the equipment and affecting its normal operation.

[0052] The material rack turret 2 is used to support the bearing turntable 3. Its design should ensure that the bearing turntable 3 is placed stably. It is equipped with a turntable pin positioning mechanism and a bearing extraction mechanism. The turntable pin positioning mechanism is used to fix the position of the bearing turntable 3 and ensure the accurate positioning of the bearing outer ring during the extraction process. The bearing extraction mechanism is used to move the bearing from the bottom of the turntable out of the bearing outer ring and move it to the designated position. Its design should ensure that the bearing outer ring can be transferred stably.

[0053] The bearing turntable 3 is used to place the outer ring of the bearing to be assembled. Its design should ensure the stable placement of the outer ring of the bearing and facilitate the removal by the bearing removal mechanism.

[0054] The camera inspection mechanism 4 is used to inspect the front and back sides of the outer ring of the bearing to be assembled, which is placed on the bearing turntable 3;

[0055] The bearing anti-slip mechanism 5 is used to transfer the outer ring of the bearing;

[0056] The barcode scanner 6 is used to scan materials, facilitating subsequent material tracking and management.

[0057] like Figure 5 As shown, the equipment protective cover 1 includes an upper limit switch 1-1, a frame 1-2, a nitrogen spring 1-3, a protective cover 1-4, a protective cover detection device 1-5, a lower limit switch 1-6, a handle 1-7, a flat plate 1-8, a partition 1-9, and a partition 1-10. The frame 1-2 is constructed of high-strength aluminum profiles, offering advantages such as light weight, high strength, and corrosion resistance, providing a stable support structure for the entire protective cover. The protective cover 1-4 is hinged to the frame 1-2, allowing it to rotate around the hinge for opening and closing. The nitrogen spring 1-3 is mounted on the protective cover 1-4 and directly connected to the frame 1-2, acting as a guide and buffer during the opening and closing of the protective cover 1-4, preventing violent collisions between the protective cover 1-4 and the frame 1-2, reducing noise, and extending the service life of both the protective cover 1-4 and the frame 1-2. The protective cover detection device 1-5 uses a proximity switch or photoelectric sensor, installed at the contact point between the frame 1-2 and the protective cover 1-4, to detect the opening and closing status of the protective cover 1-4 in real time. When the protective cover 1-4 is not fully closed, the equipment cannot start, ensuring operator safety. The upper limit 1-1 and lower limit 1-6 are set at the extreme opening and closing positions of the protective cover 1-4, respectively. The upper limit 1-1 prevents the protective cover 1-4 from opening too high, making it difficult for the operator to grip the handle 1-7, while the lower limit 1-6 prevents the protective cover 1-4 from closing excessively and scratching the workpiece inside the equipment. The handle 1-7 is located on the outside of the protective cover 1-4, facilitating opening and closing for the operator. The surface of the handle 1-7 is treated with a non-slip surface to improve operational safety. The flat plate 1-8 is located inside the protective cover and can be used to temporarily place small tools or workpieces, facilitating necessary operations during equipment operation. The partition 1-9 is located on the back of the frame 1-2 to separate the area where the camera detection mechanism 4 is located, preventing external interference and ensuring the accuracy of camera detection. 1-10 are installed on the top of the protective cover and have multiple color light display functions, which are used to indicate the status of material feeding, normal operation of equipment, fault alarm, etc., so that operators and managers can understand the operating status of the equipment in a timely manner.

[0058] like Figure 6 and Figure 7As shown, the material rack turret 2 includes a base 2-1, a mounting plate 2-2, an oil receiving pan 2-3, a slewing bearing 2-4, a rotating shaft 2-5, a connecting seat 2-6, a coupling 2-7, a reducer 2-8, a servo motor 2-9, a positioning seat 2-10, a pin 2-11, an oil-free bushing 2-12, a pin sleeve 2-13, a cylinder floating joint 2-14, a positioning cylinder 2-15, a workpiece presence sensor 2-16, a material column presence sensor 2-17, a top material overtravel sensor 2-18, a motor home position sensor 2-19, a lifting block 2-20, a lifting claw 2-21, an electric cylinder mounting plate 2-22, a linear bearing 2-23, a floating joint 2-24, a lifting electric cylinder 2-25, a guide rod 2-26, a sensing plate 2-27, a home position sensor 2-28, a limit sensor 2-29, a top material arrival sensor 2-30, and an electric cylinder zero point marker 2-31. The base 2-1 is made of cast iron and is fixed to the ground by adjusting feet. The height of the feet can be adjusted according to the flatness of the ground to ensure the levelness of the base 2-1, providing stable support for the entire material rack turret 2. The mounting plate 2-2 is made of high-strength steel plate and is fixed to the base 2-1 with bolts. The upper surface of the mounting plate 2-2 is precision machined to ensure its flatness and smoothness, providing a good reference for the installation of subsequent components. The oil tray 2-3 is located above the mounting plate 2-2 to collect lubricating oil dripping from the bearings during the conveying process, preventing lubricating oil from contaminating the equipment and the ground, and facilitating cleaning and maintenance. The slewing bearing 2-4 is fixed above the mounting plate 2-2, with its inner ring fixedly connected to the mounting plate 2-2 and its outer ring connected to the turntable. This enables smooth rotation of the turntable, reduces friction during rotation, and improves the operating accuracy and lifespan of the equipment. The rotating shaft 2-5 is mounted at the center of the mounting plate 2-2 via bearings. Its upper end is connected to the connecting plate 3-4, and its lower end is connected to the output shaft of the reducer 2-8 via coupling 2-7. The connecting seat 2-6 is fixed below the mounting plate 2-2 to support the reducer 2-8 and the servo motor 2-9, ensuring their installation stability. The reducer 2-8 is a high-precision planetary reducer connected to the servo motor 2-9, converting the high speed and low torque of the servo motor 2-9 into low speed and high torque, providing sufficient power for the rotation of the rotating shaft 2-5 and improving its rotational accuracy and stability. The servo motor 2-9 is a high-performance AC servo motor with advantages such as fast response speed, high positioning accuracy, and stable operation. It receives commands from the control system via a servo driver to achieve precise rotational control of the rotating shaft 2-5.

[0059] The positioning seat 2-10, pin 2-11, oil-free bushing 2-12, pin sleeve 2-13, cylinder floating joint 2-14, and positioning cylinder 2-15 constitute the turntable pin positioning mechanism. The positioning seat 2-10 is fixed to the mounting plate 2-2 by bolts. The positioning cylinder 2-15 is installed below the positioning seat 2-10, and its piston rod is connected to the pin 2-11 through the cylinder floating joint 2-14. The oil-free bushing 2-12 and pin sleeve 2-13 are placed inside the positioning seat 2-10. The pin 2-11 passes through the oil-free bushing 2-12 and pin sleeve 2-13. The oil-free bushing 2-12 has self-lubricating properties, which can reduce the friction of the pin 2-11 during movement. The pin sleeve 2-13 serves to guide and protect the pin 2-11. When the bearing turntable 3 needs to be positioned, the piston rod of the positioning cylinder 2-15 extends, pushing the pin 2-11 upward and inserting it into the corresponding positioning hole at the bottom of the bearing turntable 3, thus achieving precise positioning of the bearing turntable 3; when the bearing turntable 3 needs to rotate, the piston rod of the positioning cylinder 2-15 retracts, causing the pin 2-11 to move downward, disengage from the positioning hole, and release the positioning.

[0060] The workpiece presence / absence sensor 2-16, material column presence sensor 2-17, top material overtravel sensor 2-18, and motor home position sensor 2-19 are all mounted on mounting plate 2-2. The workpiece presence / absence sensor 2-16 is a diffuse reflection photoelectric sensor, installed on the manual feeding side of mounting plate 2-2, used to detect in real time whether there is a workpiece on the bearing turntable 3 on that side. When no workpiece is detected, it promptly sends a signal to the control system, issuing a material call prompt via 1-10 to remind the operator to replenish the material. The material column presence sensor 2-17 also uses a diffuse reflection photoelectric sensor, installed on the automatic feeding side of mounting plate 2-2, used to detect whether there is a bearing outer ring on the guide column 3-5 on that side, ensuring the continuity of the feeding process. The top material overtravel sensor 2-18 is a through-beam photoelectric sensor used to control the extreme position when the bearing outer ring moves upward. When the bearing outer ring rises to this position, the sensor sends a signal, and the control system controls the lifting cylinder 2-25 to stop moving, preventing the bearing outer ring from overtravel and damaging the equipment or affecting subsequent operations. The motor home position sensor 2-19 is a proximity sensor used to detect the home position of the servo motor 2-9. When the servo motor 2-9 drives the rotating shaft 2-5 to rotate to the home position, the sensor sends a signal to ensure that the equipment can return to the initial position every time it starts up, thus improving the consistency of equipment operation.

[0061] The lifting block 2-20, lifting claw 2-21, electric cylinder mounting plate 2-22, linear bearing 2-23, floating joint 2-24, lifting electric cylinder 2-25, guide rod 2-26, sensing plate 2-27, in-situ sensor 2-28, limit sensor 2-29, top material positioning sensor 2-30, and electric cylinder zero point marker 2-31 constitute the bearing extraction mechanism. The electric cylinder mounting plate 2-22 and linear bearing 2-23 are fixed to the mounting plate 2-2. The guide rod 2-26 passes through the linear bearing 2-23, and the linear bearing 2-23 provides guidance for the up-and-down movement of the guide rod 2-26, ensuring the straightness of its movement. The upper end of the guide rod 2-26 has a lifting claw 2-21, and the lower end has a sensing plate 2-27. The lifting electric cylinder 2-25 is installed below the electric cylinder mounting plate 2-22, and its output shaft is connected to the lifting claw 2-21 through the floating joint 2-24. The floating joint 2-24 compensates for installation errors between the lifting cylinder 2-25 and the lifting claw 2-21, preventing the lifting cylinder 2-25 from bearing additional radial force due to installation deviations and extending its service life. The lifting block 2-20 is mounted on the lifting claw 2-21 to support the bearing outer ring. The lifting block 2-20 is made of wear-resistant cast iron with a hardened surface to improve its wear resistance. Both the in-situ sensor 2-28 and the limit sensor 2-29 are proximity switches, installed at corresponding positions along the movement trajectory of the guide rod 2-26. When the sensing element 2-27 moves up and down with the guide rod 2-26, it triggers the corresponding sensor. When the induction plate 2-27 triggers the home position sensor 2-28, it indicates that the lifting claw 2-21 is in its initial position; when it triggers the limit sensor 2-29, it indicates that the lifting claw 2-21 has moved to the lower and upper limit positions and the material is gradually decreasing; the top material positioning sensor 2-30 is located on the gantry frame 5-1. When the top material positioning sensor 2-30 receives a signal, it indicates that the outer ring of the bearing has been lifted to the designated loading position. At this time, the control system controls the lifting cylinder 2-25 to stop rising. The cylinder zero point indicator 2-31 is located on the lifting cylinder 2-25 to mark the zero point position of the cylinder, facilitating equipment debugging and maintenance.

[0062] like Figure 8 and Figure 9As shown, the bearing turntable 3 includes mounting blocks 3-1, pads 3-2, clamps 3-3, connecting discs 3-4, guide posts 3-5, a turntable 3-6, and sensing rods 3-7. The connecting disc 3-4 is bolted to the rotating shaft 2-5 of the material rack turret 2 and rotates with the shaft 2-5. The turntable 3-6 is positioned above the slewing bearing 2-4, its lower surface connected to the outer ring of the slewing bearing 2-4, allowing it to rotate smoothly under the action of the slewing bearing 2-4. Mounting blocks 3-1 are evenly distributed around the turntable 3-6. The number of mounting blocks 3-1 can be set according to actual production needs. In this embodiment, 16 mounting blocks 3-1 are provided. Each mounting block 3-1 is bolted with 3 guide posts 3-5. The guide posts 3-5 are made of 45# steel with a chrome-plated surface, providing good wear resistance and guiding properties. They are used to limit the movement direction of the bearing outer ring, ensuring that the bearing outer ring can slide stably along the guide posts 3-5. Clamp 3-3 is mounted on guide post 3-5 and secured with bolts. It is used to fix guide post 3-5 to mounting block 3-1, preventing guide post 3-5 from loosening or shifting during operation. Spacer 3-2 passes through clamp 3-3. Spacer 3-2 is made of polyurethane and has a certain degree of elasticity, preventing hard contact between the bearing outer ring and clamp 3-3, thus buffering and protecting the bearing outer ring. Sensing rods 3-7 are evenly distributed below turntable 3-6. The number of sensing rods 3-7 corresponds to the number of mounting blocks 3-1. When turntable 3-6 rotates, the sensing rods 3-7 sequentially pass through motor in-situ sensor 2-19, providing signals for motor positioning.

[0063] like Figure 10As shown, the camera inspection mechanism 4 includes a column 4-1, a crossbeam 4-2, a connecting plate 4-3, a camera bracket 4-4, a camera protective cover 4-5, a camera assembly 4-6, and a connecting block 4-7. The column 4-1 is made of square steel and is fixed to the ground with anchor bolts, providing stable support for the entire camera inspection mechanism 4. The crossbeam 4-2 runs across the column 4-1 and is fixedly connected to the column 4-1 with bolts. The length of the crossbeam 4-2 can be adjusted according to the camera inspection range. The connecting plate 4-3 is installed on the crossbeam 4-2, and the camera bracket 4-4 is set on the connecting plate 4-3. The position of the camera bracket 4-4 on the connecting plate 4-3 can be adjusted with bolts to precisely adjust the camera's inspection position. The camera protective cover 4-5 is installed below the camera bracket 4-4 and is made of transparent acrylic material. It protects the camera assembly 4-6 from external dust, oil, and other contaminants without affecting the camera's field of view. Camera assembly 4-6 is fixed below connecting block 4-7 and located inside camera protective cover 4-5. Camera assembly 4-6 includes an industrial camera and a lens. The industrial camera is a high-resolution CCD camera, and the lens is a telecentric lens, which ensures that the image magnification does not change with the object distance within a certain object distance range, ensuring the accuracy of detection. Connecting block 4-7 is set above camera bracket 4-4 to fix camera assembly 4-6. By adjusting the position of connecting block 4-7 on camera bracket 4-4, the up / down and left / right adjustments of camera assembly 4-6 can be achieved, further ensuring the accuracy of the detection position. Camera detection mechanism 4 takes pictures of the bearing outer ring through the industrial camera and transmits the image information to the image processing system. The image processing system analyzes and processes the image to determine the front and back of the bearing outer ring and feeds the results back to the control system, providing a basis for subsequent robot grasping.

[0064] like Figure 11 and Figure 12As shown, the bearing anti-lifting mechanism 5 includes a gantry frame 5-1, gripper one 5-2, gripper two 5-3, clamping block 5-4, guide rail 5-5, cylinder mounting bracket 5-6, cylinder 5-7, limit assembly 5-8, adjustment assembly 5-9, slider mounting plate 5-10, gripper cylinder mounting plate 5-11, sensor assembly 5-12, connector fixing block 5-13, floating connector two 5-14, gripper cylinder 5-15, and magnetic switch assembly 5-16. The gantry frame 5-1 is welded from structural steel and fixed to the mounting plate 2-2 of the material rack turret 2, providing stable support for the entire anti-lifting mechanism. The guide rail 5-5 is located directly below the gantry frame 5-1 and uses a high-precision linear guide rail 5-5 to ensure the smoothness and accuracy of the slider's movement on it. The cylinder mounting bracket 5-6 is located at the rear end of the guide rail 5-5 and is used to mount the cylinder 5-7. The cylinder 5-7 is a double-acting cylinder, and its piston rod is connected to the connector fixing block 5-13 via the floating joint 5-14. The connector fixing block 5-13 is connected to the slider mounting plate 5-10, which is fixed to the slider of the guide rail 5-5. When the piston rod of the cylinder 5-7 extends or retracts, it can drive the slider mounting plate 5-10 and other connected components to move back and forth along the guide rail 5-5. The limiting component 5-8 is located at the front end of the guide rail 5-5 and is used to limit the forward limit position of the slider mounting plate 5-10 to prevent the slider mounting plate 5-10 from colliding with other components. The adjusting components 5-9 are located on both sides of the slider mounting plate 5-10. The position of the slider mounting plate 5-10 on the guide rail 5-5 can be finely adjusted by adjusting the bolts to ensure the positioning accuracy of the gripper.

[0065] The gripper cylinder mounting plate 5-11 is fixed below the slider mounting plate 5-10, and the gripper cylinder 5-15 is located below the gripper cylinder mounting plate 5-11. The gripper cylinder 5-15 adopts a parallel opening and closing type pneumatic gripper, which has the characteristics of stable clamping force and rapid action. Grippers 1 5-2 and grippers 2 5-3 are respectively located on both sides of the front end of the gripper cylinder 5-15. The clamping block 5-4 is installed inside grippers 1 5-2 and grippers 2 5-3. The clamping block 5-4 is made of rubber, which has good elasticity and friction, and can avoid damaging the surface of the bearing outer ring when clamping it, while ensuring the stability of the clamping and preventing the bearing outer ring from falling off during the transfer process. Sensor assembly 5-12 is located on the side of gripper cylinder 5-15 and fixed below gantry frame 5-1. It employs a proximity sensor to detect whether the gripper is in its home or working position. When gripper cylinder 5-15 moves to the corresponding position along guide rail 5-5 under the drive of cylinder 5-7, the sensor sends a signal to the control system. Magnetic switch assembly 5-16 is embedded in the surface of gripper cylinder 5-15 to detect the extension and retraction state of the piston rod, thereby determining the gripping and releasing state of the gripper and ensuring reliable execution of the gripping action.

[0066] The working process of this utility model is as follows:

[0067] Manual material replenishment stage: The operator opens the protective cover 1-4 of the equipment protective cover 1 and places the outer rings of the bearings to be assembled one by one into the guide posts 3-5 of the bearing turntable 3. During the material replenishment process, the barcode scanner 6 scans the QR code on each outer ring of the bearing. The scanned information is transmitted to the control system in real time for storage, facilitating subsequent material tracking. After the material is assembled, the operator closes the protective cover 1-4. The protective cover detection device 1-5 detects that the protective cover 1-4 is closed in place and sends a signal to the control system.

[0068] Initial positioning stage: After receiving the signal that the protective cover 1-4 is closed in place, the control system issues a start command. First, the turntable pin positioning mechanism on the material rack turret 2 starts to work. The piston rod of the positioning cylinder 2-15 extends and drives the pin 2-11 upward through the cylinder floating joint 2-14. The pin 2-11 passes through the oil-free bushing 2-12 and the pin sleeve 2-13 and is inserted into the corresponding positioning hole at the bottom of the bearing turntable 3, realizing the initial positioning of the bearing turntable 3.

[0069] Bearing extraction stage: The bearing extraction mechanism starts to operate. The lifting cylinder 2-25 receives the command from the control system and extends its output shaft upward. Through the floating joint 2-24, it drives the lifting claw 2-21 to move upward. The guide rod 2-26 slides upward within the linear bearing 2-23, and the lifting block 2-20 mounted on the lifting claw 2-21 moves upward accordingly, lifting the pad 3-2 located at the bottom of the guide column 3-5 and the bearing outer ring placed on it. When the bearing outer ring is lifted to the designated position, the top material positioning sensor 2-30 receives the positioning signal and sends a signal to the control system. The control system then controls the lifting cylinder 2-25 to stop moving.

[0070] Front and back inspection stage: Camera inspection mechanism 4 starts working, and industrial cameras 4-6 take pictures of the lifted bearing outer ring. The captured image information is transmitted to the image processing system. The image processing system analyzes the image to determine the front and back of the bearing outer ring. If the front of the bearing outer ring is facing up, the image processing system sends a pass signal to the control system; if the back is facing up, it sends a fail signal.

[0071] Bearing transfer stage: If the outer ring of the bearing is facing upwards, the control system activates the bearing anti-lifting mechanism 5. First, the piston rod of cylinder 5-7 extends, driving the slider mounting plate 5-10 and other connected components forward along the guide rail 5-5 via floating joint 2 5-14 and joint fixing block 5-13, until the slider mounting plate 5-10 touches the limit component 5-8. Cylinder 5-7 stops moving and reaches the working position of the gripper. At this time, the gripper fingers of gripper cylinder 5-15 are in the open state. Then, gripper cylinder 5-15 operates, driving gripper 1 5-2 and gripper 2 5-3 to move towards the center, and clamping block 5-4 clamps the outer ring of the bearing. Magnetic switch component 5-16 detects that the gripper fingers of gripper cylinder 5-15 are closed and sends a signal to the control system. Subsequently, the robot gripper picks up the outer ring of the bearing and places it on the assembly station.

[0072] Material switching phase: After all the bearing outer rings on a set of guide columns 3-5 have been extracted, the material presence sensor 2-17 detects that there is no material on that set of guide columns 3-5 and sends a signal to the control system. The control system controls the piston rod of the positioning cylinder 2-15 to retract, causing the pin 2-11 to move downwards, disengaging from the positioning hole of the bearing turntable 3, and releasing the positioning. Subsequently, the servo motor 2-9 starts, driving the rotating shaft 2-5 to rotate through the reducer 2-8 and coupling 2-7. The rotating shaft 2-5 drives the connecting plate 3-4 and the turntable 3-6 to rotate together, and the outer ring of the rotary bearing 2-4 rotates synchronously with the turntable 3-6. When the turntable 3-6 rotates to the next set of guide columns 3-5 with bearing outer rings aligned with the bearing extraction mechanism, the motor in-situ sensor 2-19 detects the sensing rod 3-7 below the turntable 3-6 and sends a signal to the control system, and the servo motor 2-9 stops rotating. At this point, the piston rod of the positioning cylinder 2-15 extends again, and the pin 2-11 is inserted into the positioning hole of the bearing turntable 3 to achieve secondary positioning, preparing for the extraction of the next set of bearing outer rings.

[0073] Material replenishment prompt stage: After all the bearing outer rings of the guide pillars 3-5 on the bearing turntable 3 have been extracted, the workpiece presence sensor 2-16 detects no workpiece and sends a signal to the control system. The control system then controls the tower light 1-10 to emit a yellow material replenishment prompt light to remind the operator to replenish the material. The operator opens the protective cover 1-4 to replenish the material and repeats the above process.

[0074] Troubleshooting Phase: During equipment operation, if issues such as protective covers 1-4 not being properly closed, bearing outer ring overtravel, or sensor malfunction occur, the control system will immediately issue a stop command and activate tower lights 1-10 to emit red alarm lights. Simultaneously, the fault information will be displayed on the control system's screen for timely troubleshooting and resolution by maintenance personnel. After the fault is resolved, the operator presses the reset button, and the equipment returns to normal operation.

[0075] This utility model's bearing outer ring feeding tower, through the coordinated operation of the aforementioned mechanisms, achieves an automated feeding process for bearing outer rings. A single feeding cycle can meet 0.5 hours of production needs, significantly reducing the frequency of manual feeding and improving production efficiency. The equipment's components are rationally designed, precisely positioned, and operate stably, effectively ensuring the quality of bearing assembly, reducing labor costs and intensity, and possessing high value for widespread application.

[0076] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
