Description

Technical Field

[0001] This invention relates to the technical field of bearing manufacturing, and more specifically, to a fully automated inspection device for bearing ring manufacturing processes. Background Technology

[0002] During the grinding process of bearing rings, it is necessary to inspect the outer diameter, inner diameter, and roundness of the rings to monitor the machining quality. To achieve online full inspection, existing technologies have developed automated inspection equipment that uses expensive components such as high-precision air-bearing spindles, precision servo motors, and laser displacement sensors.

[0003] However, due to the high cost of automated testing equipment, a complete online testing system often costs hundreds of thousands or even millions of yuan, which is unaffordable for small and medium-sized bearing manufacturers. Therefore, how to provide a bearing ring testing device that can meet the requirements of online full inspection between processes and is also cost-effective is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] To address the shortcomings of existing online bearing ring inspection equipment, which is costly due to the use of expensive components such as high-precision air-bearing spindles, precision servo motors, and laser displacement sensors, making it unaffordable for small and medium-sized bearing manufacturers, this invention provides a fully automated inter-process inspection device for bearing rings to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic inter-process inspection device for bearing rings, comprising: The detection frame has a feeding channel on one side, a discharging channel on the other side, and a waste outlet at the bottom. The detection box is installed on the rear side of the detection frame; A support roller assembly is disposed outside the detection box and includes two H-shaped rollers, one of which is connected to a first drive assembly to adjust the distance between the two H-shaped rollers, thereby achieving selective discharge of qualified products and unqualified products. The support assembly is horizontally movable inside the detection box and is driven to move horizontally by the second drive assembly; The detection component, disposed on the bracket assembly, includes a lifting assembly, and a first detection component and a second detection component mounted on the lifting assembly. The first detection component is used to detect the outer diameter of the bearing ring, and the second detection component is used to detect the inner diameter of the bearing ring. A rotary drive assembly, mounted on the lifting assembly, is used to press and drive the bearing rings to rotate.

[0006] By setting up a detection frame and feeding and discharging channels, gravity feeding and discharging are achieved. H-shaped rollers are used as supports and discharge actuators, electric push rods are used as drive components, and electronic lever dial indicators are used as detection elements. All components are standard parts or low-cost machined parts, eliminating the need for expensive components such as high-precision air-bearing spindles, precision servo motors, and laser displacement sensors, which greatly reduces equipment costs and makes it affordable for small and medium-sized bearing manufacturing enterprises.

[0007] Furthermore, the two H-shaped rollers are installed at different heights, with the H-shaped roller located on the feed channel side having a higher installation height than the H-shaped roller located on the discharge channel side.

[0008] By setting the H-shaped roller on the feed channel side higher than the discharge channel side, the rings automatically move towards the lower side (discharge channel side) during measurement, achieving axial positioning and ensuring that the inner diameter probe is inserted in the same position each time, thus improving measurement repeatability. On the other hand, when the first drive assembly pushes the qualified rings towards the discharge channel, the rings naturally roll out along the slope, allowing for smooth discharge without additional thrust, thus reducing the drive load.

[0009] Furthermore, the support assembly includes: A sliding frame is installed inside the detection box; Guide rails are set on both sides of the sliding frame and are slidably connected to the guide rails on both sides inside the detection box; The second driving component is connected to the sliding box and is used to drive the sliding box to move horizontally.

[0010] The sliding frame and the detection box adopt a sliding fit structure of guide rail and guide groove, which is simple to process, easy to assemble, and low in cost.

[0011] Furthermore, the lifting assembly includes: The screw is vertically installed inside the sliding frame, and its upper end is connected to a first motor, which is mounted on the sliding frame. The first mounting plate is horizontally positioned above the inside of the sliding frame and is threadedly engaged with the first threaded section of the screw. The second mounting plate is located below the first mounting plate and is threadedly engaged with the second threaded section of the screw. The third mounting plate is located below the second mounting plate and is threaded into the third threaded section of the screw. Vertical sliding rods are installed at the four corners inside the sliding frame and are slidably connected to the first mounting plate, the second mounting plate, and the third mounting plate, respectively. The first thread segment and the third thread segment have the same thread direction, while the first thread segment and the second thread segment have opposite thread directions.

[0012] The screw drives the three mounting plates to rise and fall simultaneously. By utilizing the cooperation of positive and negative threads, the first and second mounting plates move in opposite directions, while the first and third mounting plates move in the same direction. This achieves synchronous opposite-direction movement of the outer diameter probe descending, the inner diameter probe rising, and the drive roller descending. This significantly reduces the number of drive components, greatly reduces manufacturing costs and control complexity, and provides good motion synchronization, simple debugging, and reliable operation.

[0013] Furthermore, the first detection component and the second detection component are electronic lever dial indicators, with the first detection component mounted on the first mounting plate and the second detection component mounted on the second mounting plate.

[0014] Using an electronic lever dial indicator as the inner and outer diameter measuring element significantly reduces costs while ensuring measurement accuracy, fully meeting the precision requirements for inter-process inspection of bearing rings. Furthermore, it features a built-in data output interface, allowing direct connection to a PLC or microcontroller for easy automation integration.

[0015] Furthermore, the rotary drive assembly is mounted on the lower surface of the third mounting plate, and includes: The second motor is mounted on the lower surface of the third mounting plate; A spring box is located on the lower surface of the third mounting plate. Its input end is connected to the rotating end of the second motor via an electromagnetic clutch, and its output end is connected to a rubber-coated roller. The rubber-coated roller is used to press the inner wall of the bearing ring and drive it to rotate by friction. The second motor is used to store energy for the spring in the spring box; when the electromagnetic clutch is disengaged, the spring releases energy and drives the rubber-coated roller to rotate.

[0016] By combining a second motor, a spring box, and an electromagnetic clutch, the problem of motor vibration affecting measurement accuracy is fundamentally solved at a very low cost. During measurement, the electromagnetic clutch is disengaged, the second motor is completely separated from the rubber-coated roller, and the spring independently releases energy to drive the bearing ring to rotate. When the motor stops, there is no vibration, ensuring measurement stability.

[0017] Furthermore, the spring box, electromagnetic clutch, and rubber-coated roller are all standard parts or mature mechanical components, with simple structure, convenient installation, and low replacement cost after damage.

[0018] Furthermore, the first drive assembly and the second drive assembly are electric actuators.

[0019] Using a high-precision electric linear actuator as the drive component is far less expensive than the combination of a servo motor and a lead screw, and it is simple to control and meets the accuracy requirements.

[0020] Furthermore, the selective discharge of the support roller assembly is configured as follows: When the bearing ring is a qualified product, the first drive assembly drives the H-shaped roller to move horizontally to another H-shaped roller, pushing the bearing ring towards the discharge channel; When the bearing ring is defective, the first drive assembly drives the H-shaped rollers to move in the opposite direction, increasing the distance between the two H-shaped rollers and causing the bearing ring to fall from between the two H-shaped rollers to the waste outlet.

[0021] The same set of H-shaped rollers enables two discharge methods for qualified and unqualified products, eliminating the need for additional pusher cylinders or sorting flaps. This simple structure completes the sorting function and reduces costs.

[0022] Furthermore, it also includes a waste screening mechanism, disposed below the detection frame, the waste screening mechanism comprising: The first waste channel is slidably set on one side below the detection frame to receive reworkable bearing rings; The second waste channel is slidably set on the other side below the detection frame and is fixedly connected to the first waste channel. It is used to receive non-repairable pure waste bearing rings. The third drive assembly, installed on the lower surface of the detection box, is an electric push rod. Its telescopic end is fixedly connected to the second waste channel and is used to adjust the position of the first waste channel and the second waste channel so as to selectively move the first waste channel or the second waste channel directly below the waste port to switch the receiving of the falling bearing rings.

[0023] The structure employs an electric push rod-driven dual-channel integral sliding mechanism, enabling further subdivision of non-conforming products at low cost (reworkable products and pure waste products are collected separately), without the need for complex pneumatic or servo control systems.

[0024] Furthermore, it also includes a control component, which is electrically connected to the first drive component, the second drive component, the lifting component, the first detection component, the second detection component, the rotary drive component, and the waste screening mechanism, respectively. The control component is used to receive measurement data and determine whether the bearing rings are qualified, and control the operation of the first drive component, the second drive component, the lifting component, the rotary drive component, and the waste screening mechanism according to the determination result.

[0025] Using conventional PLCs or microcontrollers as control components, full-process automated control is achieved at a cost of tens of yuan, eliminating the need for expensive industrial PCs or dedicated controllers. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example

[0029] like Figures 1 to 6 As shown in the figure, the fully automatic bearing ring inter-process inspection device provided in this embodiment is designed with low cost as the goal. All components are made of standard parts or low-cost processed parts. It mainly consists of inspection frame 1, inspection box 2, support roller assembly, bracket assembly, lifting assembly, inspection assembly, rotation drive assembly, waste screening mechanism and control assembly.

[0030] The detection box 1 is made of welded square steel pipes or assembled aluminum alloy profiles, which has low material cost and simple processing.

[0031] A feed channel 11 is installed on the left side of the inspection frame 1. The feed channel 11 is fixedly installed at an inclination angle of 3°-5° to the horizontal plane, allowing the bearing rings to roll downwards along the channel under their own weight. A discharge channel 12 is installed on the right side of the inspection frame 1, also inclined downwards, allowing the bearing rings to roll out along the channel under their own weight. The feed channel 11 and the discharge channel 12 are V-groove or square narrow groove structures, made of bent steel plate or aluminum alloy profiles. A waste outlet 13 is provided at the bottom center of the inspection frame 1 for the discharge of defective products.

[0032] The inspection box 2 is fixedly installed on the rear side of the inspection frame 1. The inspection box 2 is made of ordinary steel plate bent and welded, and its interior has space to accommodate various components. The inspection box 2 is fixedly connected to the inspection frame 1 by bolts. The front side (the side facing the inspection frame) of the inspection box 2 has corresponding protrusion holes so that the inspection components and rotary drive components can extend out of the inspection box 2 to perform dimensional inspection of the bearing rings.

[0033] A support roller assembly is located on the lower outer side of the testing box 2. This assembly, situated inside the testing frame 1, mainly comprises two spaced-apart rotatable H-shaped rollers 3. The H-shaped rollers 3 use standard H-shaped guide rollers, with axially spaced grooves on their circumferential surfaces matching the size of the bearing races. Nylon liners are embedded within these grooves, and their surfaces are smooth. When the bearing races fall into these grooves, they directly contact the nylon liners, causing the H-shaped rollers 3 to rotate passively through rolling friction.

[0034] The right-hand H-shaped roller 3 is a fixed roller, its roller shaft fixedly mounted on the detection box 2 via bearings and bearing seats. The left-hand H-shaped roller 3 is a movable roller, its roller shaft mounted on a linear guide slider via bearings. The linear guide slider is slidably mounted on the linear guide, allowing the movable roller to move left and right horizontally. The linear guide uses a common miniature linear guide (such as the MGN series), costing approximately tens of yuan. The movable roller is adjusted by a first drive assembly 31, which is a high-precision electric push rod. The cylinder of the electric push rod is fixed to the detection box 2, and its telescopic rod is fixedly connected to the linear guide slider via a bracket.

[0035] Specifically, the installation height of the left H-shaped roller 3 is higher than that of the right H-shaped roller 3, thus setting the two H-shaped rollers 3 at different heights. When the bearing ring rolls along the feed channel 11 between the two H-shaped rollers 3, due to the certain distance between the two H-shaped rollers 3 and the grooves on their surfaces, the bearing ring automatically falls downwards under its own weight, its outer circle engaging with the grooves of the two rollers and being stably confined between the two H-shaped rollers 3. At the same time, the feed channel 11 is set at a small angle (3°-5° with the horizontal plane), which makes the rolling speed of the ring low, the impact force small, and the ring will not bounce when it falls, allowing it to fall smoothly into the predetermined measurement position.

[0036] During operation, after the bearing ring inspection is completed, when the control component 6 determines that the bearing ring is qualified, it controls the first drive component 31 to drive the movable roller to move horizontally to the right (towards the fixed roller). This causes the movable roller to push the bearing ring to the right, which in turn causes the bearing ring to roll towards the fixed roller and into the discharge channel 12, where it is discharged by gravity. When the control component 6 determines that the bearing ring is unqualified, it controls the first drive component 31 to drive the movable roller to move horizontally to the right (away from the fixed roller). This increases the distance between the two H-shaped rollers 3 to a value greater than the outer diameter of the bearing ring. At this point, the bearing ring loses its support and falls from between the two H-shaped rollers 3 into the waste outlet 13 below.

[0037] Inside the testing chamber 2, above the supporting roller assembly 3, a bracket assembly is installed. The bracket assembly includes a sliding frame 4. The sliding frame 4 is constructed from welded square steel tubing or spliced ​​aluminum plates, forming a rectangular frame structure. It is made from common materials, resulting in low cost. Guide rails are fixedly installed on the left and right outer walls of the sliding frame 4. Correspondingly, guide grooves that mate with the guide rails are fixedly installed on the left and right inner walls of the testing chamber 2. Ball bearings or sliding bushings are provided between the guide rails and guide grooves to reduce friction. The guide rails and guide grooves use standard miniature linear guide assemblies (such as the MGN series), costing approximately tens of yuan.

[0038] The sliding frame 4 is driven to move horizontally by the second drive assembly 41. The second drive assembly 41 is also a high-precision electric push rod, using the same model as the first drive assembly 31, which facilitates spare parts management. The cylinder of the electric push rod is fixed to the rear side wall or bottom plate of the detection box 2, and its telescopic rod is fixedly connected to the rear side or bottom of the sliding frame 4.

[0039] In operation, once the bearing ring enters the measuring position, the control component 6 controls the second drive component 41 to extend, pushing the sliding frame 4 forward (towards the detection frame) horizontally, allowing the detection component and rotary drive component mounted on the sliding frame 4 to enter the measuring working position. After measurement, the control component 6 controls the second drive component 41 to retract, causing the sliding frame 4 to move backward, allowing the detection component and rotary drive component to exit, making space for the bearing ring to enter, exit, and be sorted.

[0040] Inside the sliding frame 4, a lifting assembly is installed. The core design of the lifting assembly is that a single screw drives the lifting of three mounting plates simultaneously, replacing the traditional design that requires three independent lifting mechanisms with a single motor, thus significantly reducing costs.

[0041] The specific structure is as follows: The lifting assembly includes a vertically arranged screw 42. The screw 42 is a common trapezoidal lead screw or ball screw, costing approximately tens to hundreds of yuan. The upper end of the screw 42 passes through the top plate of the sliding frame 4 and is connected to the output shaft of the first motor 421 via a coupling. The first motor 421 is a common stepper motor, costing approximately one hundred yuan, far lower than a servo motor. The first motor 421 is fixedly mounted on the upper surface of the top plate of the sliding frame 4.

[0042] The screw 42 is provided with a first threaded section 422, a second threaded section 423 and a third threaded section 424 from top to bottom. The first threaded section 422 and the third threaded section 424 have the same thread direction (for example, both are right-hand threads), while the second threaded section 423 has the opposite thread direction to the first threaded section 422 (for example, a left-hand thread).

[0043] Four vertical sliding rods 43 are fixedly installed at the four corners inside the sliding frame 4. The vertical sliding rods 43 are made of ordinary chrome-plated round steel, which is low in cost, and their upper and lower ends are fixed to the top plate and bottom plate of the sliding frame 4, respectively.

[0044] Inside the sliding frame 4, from top to bottom, are arranged a first mounting plate 44, a second mounting plate 45, and a third mounting plate 46, all horizontally positioned within the sliding frame 4 and made of ordinary steel plate. Linear bearings or sliding sleeves are installed at the four corners, fitted onto four vertical sliding rods 43, allowing them to slide up and down along the vertical sliding rods 43. The linear bearings are standard parts, costing approximately several to over ten yuan each.

[0045] The first mounting plate 44 is provided with a threaded hole, which is threadedly engaged with the first threaded section 422. The second mounting plate 45 is provided with a threaded hole, which is threaded to the second threaded section 423; the third mounting plate 46 is provided with a threaded hole, which is threaded to the third threaded section 424.

[0046] In use, when the control component 6 controls the first motor 421 to drive the screw 42 to rotate, since the first thread segment 422 is a positive thread, the second thread segment 423 is a negative thread, and the third thread segment 424 is a positive thread, the first mounting plate 44 and the third mounting plate 46 move downwards synchronously, and the second mounting plate 45 moves upwards synchronously. This achieves synchronous control of the first detection component 441 descending, the second detection component 451 ascending, and the rotation drive component descending. When the first motor 421 reverses, each mounting plate moves in the opposite direction and returns to its initial position. This "one-drive-three" structural design, compared to the traditional solution which requires three independent lifting mechanisms (three motors or three cylinders), significantly reduces the number of drive components, and substantially lowers manufacturing costs and control complexity.

[0047] The detection components include a first detection component 441 and a second detection component 451, both employing electronic lever dial indicators. Electronic lever dial indicators are mature standard measuring instruments, costing approximately several hundred yuan, far lower than laser displacement sensors (thousands to tens of thousands of yuan), and achieving an accuracy of 0.001 mm, meeting the inter-process inspection requirements for bearing rings. Both electronic lever dial indicators are equipped with data output interfaces (such as RS232 or Bluetooth), electrically connected to the control component 6 via data cables to transmit measurement data in real time.

[0048] The housing of the first detection component 441 (outer micrometer) is fixed to the lower surface of the first mounting plate 44 by a bracket, and its probe is set at an angle downward. The housing of the second detection component 451 (inner micrometer) is fixed to the upper surface of the second mounting plate 45 by a bracket, and its probe is set at an angle upward.

[0049] As the first mounting plate 44 descends, the probe contacts the highest point of the outer diameter of the bearing race from above. The control component 6 controls the descent stroke of the first mounting plate 44 to generate a preload of approximately 0.05-0.1 mm in the probe, and then returns the reading to zero via the control component 6. When the race rotates, the probe extends and retracts following the minute undulations of the outer diameter surface; the change in reading represents the outer diameter roundness error. Comparing the average reading with the standard value yields the outer diameter deviation.

[0050] During installation, after adjusting the first mounting plate 44 and the second mounting plate 45 to the testing position, the operator places a standard bearing race on the two H-shaped rollers 3. The probe of the first testing component 441 contacts the highest point of the outer circumference of the bearing race from above, while the probe of the second testing component 451 extends into the inner hole of the bearing race from below, contacting the lower part of the inner wall. Simultaneously, the two probes generate a certain preload (e.g., 0.05-0.1 mm). At this point, the current readings of the first testing component 441 and the second testing component 451 are reset to zero, completing the calibration of the testing components.

[0051] In use, as the first mounting plate 44 and the second mounting plate 45 are adjusted to the detection position, the probes of the first detection component 441 and the second detection component 451 contact the inner and outer sides of the bearing ring respectively. By rotating the bearing ring, the probes swing along with the surface undulations of the inner and outer walls. The change in reading is the roundness error of the inner and outer surfaces. The inner diameter deviation can be obtained by comparing the average reading with the standard value.

[0052] Control component 6 collects measurement data output by the first detection component 441 and the second detection component 451 in real time during one or more rotations of the bearing ring. It calculates the maximum, minimum, and average values ​​of the outer diameter, and the maximum, minimum, and average values ​​of the inner diameter. Based on the difference between the average values ​​of the outer and inner diameters, it calculates the wall thickness. Based on the difference between the maximum and minimum values ​​of the outer diameter, it calculates the outer roundness error. Based on the difference between the maximum and minimum values ​​of the inner diameter, it calculates the inner roundness error. Control component 6 compares the calculated outer diameter, inner diameter, wall thickness, and roundness error with preset standard tolerance ranges to determine whether the bearing ring is qualified.

[0053] The rotary drive assembly is mounted on the lower surface of the third mounting plate 46 and is used to press and drive the bearing rings to rotate. One of the innovations of this invention is the use of a combination of a spring box and an electromagnetic clutch, which solves the problem of motor vibration affecting measurement accuracy at a very low cost (the spring box costs only a few to tens of yuan, and the electromagnetic clutch costs about tens to hundreds of yuan).

[0054] The specific structure is as follows: The rotary drive assembly includes a second motor 461, a spring box 462, an electromagnetic clutch 463, and a rubber-coated roller 464.

[0055] The second motor 461 is a common micro DC motor or stepper motor, costing approximately tens to over one hundred yuan, far lower than a high-precision servo motor. The housing of the second motor 461 is mounted on one side of the lower surface of the third mounting plate 46 via shock-absorbing elements (such as rubber pads) to reduce the transmission of vibrations during motor operation.

[0056] The spring box 462 is also mounted on the lower surface of the third mounting plate 46, located on one side of the second motor 461. The spring box 462 is a common mechanical spring box, which houses a flat spiral spring. The inner end of the spring is connected to the spring shaft, and the outer end is connected to the housing of the spring box 462. The spring is a mature standard mechanical component with extremely low cost.

[0057] An electromagnetic clutch 463 is positioned between the output shaft of the second motor 461 and the input shaft of the spring box 462. The electromagnetic clutch 463 is a miniature dry electromagnetic clutch, costing approximately tens to hundreds of yuan. The driving disc of the electromagnetic clutch 463 is fixedly connected to the rotating end of the second motor 461, and the driven disc is fixedly connected to the spring shaft of the spring box 462. The electromagnetic clutch 463 engages when energized and disengages when de-energized. The power supply line of the electromagnetic clutch 463 is electrically connected to the control component 6, which controls its on / off state.

[0058] The rubber-coated roller 464 is connected to the spring shaft of the spring box 462. The surface of the rubber-coated roller 464 is covered with a rubber layer or a polyurethane layer to increase the coefficient of friction and protect the inner wall of the raceway from scratches. The rubber-coated roller 464 uses a common steel roller with a rubber coating, which is low in cost.

[0059] In operation, before the third mounting plate 46 descends to its final position, the control component 6 pre-energizes and engages the electromagnetic clutch 463, then controls the second motor 461 to rotate, storing energy in the mainspring spring within the mainspring spring box 462 (i.e., tightening the mainspring). After energy storage is complete, the control component 6 stops the second motor 461. Then, when the third mounting plate 46 descends to its final position, the rubber-coated roller 464 extends into the inner hole of the bearing ring, pressing against the inner wall of the ring. The control component 6 then de-energizes and disengages the electromagnetic clutch 463. At this point, the input end of the mainspring spring box 462 is completely disengaged from the second motor 461, and the mainspring spring begins to release energy, driving the rubber-coated roller 464 to rotate. This allows the rubber-coated roller 464 to smoothly rotate the bearing ring through friction.

[0060] It should be noted that the rotating end of the second motor 461 is equipped with a one-way bearing. By setting the one-way bearing, when the second motor 461 stops, the spring in the spring box 462 will not drive the output shaft of the second motor 461 to reverse after the spring has finished storing energy, so as to ensure the energy storage of the spring.

[0061] Since the second motor 461 is stopped and the electromagnetic clutch 463 is disengaged during the measurement process, motor vibration is completely isolated and will not be transmitted to the raceway and detection components. The release of energy by the spring is a purely mechanical and smooth physical process that does not generate any high-frequency vibration or electromagnetic interference, ensuring stable contact of the dial indicator probe and meeting the requirements for micron-level roundness measurement.

[0062] As a preferred embodiment, to prevent uneven rotational speed due to torque attenuation when the spring releases energy, the roller shaft of the rubber-coated roller 464 is mounted on the third mounting plate 46 via a damping bearing. The damping bearing provides a smooth damping torque to suppress rotational speed fluctuations, ensuring smooth rotation of the raceway and thus improving measurement accuracy. Due to the presence of the damping bearing, in this preferred embodiment, the third mounting plate 46 is a convex horizontal plate with its protrusion facing forward, and the damping bearing is mounted below this protrusion.

[0063] Below the detection box 1, directly below the waste inlet 13, is a waste screening mechanism. The waste screening mechanism includes a first waste channel 51, a second waste channel 52, and a third drive assembly 5. This mechanism uses a low-cost electric push rod to drive the entire dual-channel sliding mechanism, achieving the separate collection of reworkable and pure waste products.

[0064] The first waste channel 51 and the second waste channel 52 are both inclined chutes, made of bent ordinary steel plates. They are arranged side-by-side and fixedly connected as one unit by a connecting plate, but their inclination directions are opposite: the first waste channel 51 inclines to the left, with its outlet facing left, guiding repairable bearing rings to the repairable collection box on the left; the second waste channel 52 inclines to the right, with its outlet facing right, guiding non-repairable scrap bearing rings to the scrap collection box on the right. The first waste channel 51 and the second waste channel 52 are slidably installed below the detection frame 1 via simple linear guide rails.

[0065] The third drive assembly 5 is installed on the lower surface of the detection box 2. The third drive assembly 5 uses the same model of electric push rod as the first drive assembly 31 for easy spare parts management. The telescopic end of the electric push rod is fixedly connected to the second waste channel 52.

[0066] In operation, when control component 6 determines that a defective ring is reworkable, it controls the third drive component 5 to extend, driving the dual-channel assembly to move. This causes the first waste channel 51 to move directly below the waste inlet 13, and the falling defective ring enters the first waste channel 51 and slides into the reworkable collection box. When control component 6 determines that a defective ring is pure scrap, it controls the third drive component 5 to reverse, causing the second waste channel 52 to move directly below the waste inlet 13. The falling defective ring enters the second waste channel 52 and slides into the pure scrap collection box.

[0067] The control component 6 is installed in a suitable location outside the detection box 2. It uses a programmable logic controller (PLC) or a microcontroller development board, and its cost is approximately tens to hundreds of yuan, which is far lower than that of expensive industrial control computers. The control component 6 is electrically connected to the first drive component 31, the second drive component 41, the first motor 421, the second motor 461, the electromagnetic clutch 463, the third drive component 5, the first detection component 441, and the second detection component 451 via cables.

[0068] In summary, all components used in this embodiment are standard parts or low-cost machined parts. The material cost of the entire device can be controlled within several thousand yuan, which is only a fraction of the cost of existing equipment (usually hundreds of thousands of yuan), making it fully affordable for small and medium-sized bearing manufacturing enterprises.
