Abstract
Description
Technical Field
[0001] This invention relates to the field of bearing testing technology, specifically to a bearing testing device with adaptive functions. Background Technology
[0002] Bearing inspection is a process of evaluating the working condition and performance of bearings through a series of technical means. Its core purpose is to detect early defects and prevent sudden failures, thereby ensuring the safe and stable operation of equipment. Common inspection methods include vibration analysis, noise monitoring, temperature measurement, and lubricant inspection. By capturing and analyzing abnormal signals, it is determined whether the bearing has wear, fatigue, corrosion, or assembly problems. It is not only used for fault diagnosis but also provides a basis for equipment maintenance, making it a crucial link in achieving predictive maintenance and extending equipment life.
[0003] Currently, the quality inspection of bearing products commonly relies on manual labor or single fixtures for positioning and inspection, which is insufficient to efficiently meet the continuous inspection needs of bearings of various specifications. Existing inspection equipment often lacks flexible size adaptability, requiring frequent fixture changes for bearings with different outer or inner diameters, severely limiting inspection efficiency. Furthermore, rigid clamping methods can easily scratch the bearing surface, affecting product quality. In addition, common inspection mechanisms typically lack built-in pre-screening functions, leading to mixed inspection of bearings of different specifications, further increasing the risk of false positives and operational complexity. Regarding mechanism reset and clamp release, most devices still rely on external power or manual intervention, resulting in delayed response, difficulty in achieving precise timing coordination, and limitations on improving the overall automation level. These problems highlight the shortcomings of existing bearing inspection devices in terms of flexibility, integration, and intelligence, urgently requiring a new inspection solution that can adapt to bearing dimensions, achieve linked clamping and inspection, and possess automatic reset functionality.
[0004] In view of this, we propose a bearing testing device with adaptive function. Summary of the Invention

[0018] By employing the above technical solution, the present invention provides a bearing testing device with adaptability. It possesses at least the following beneficial effects:
[0019] 1. This invention triggers the lifting mechanism of the outer diameter adapter component by detecting the downward pressure of the robotic arm. Combined with the rotational motion of the turntable, it cleverly utilizes mechanical transmission to convert the rotational motion into radial movement of the clamping block, thereby achieving adaptive envelope clamping of bearings with different outer diameters. Simultaneously, the inner diameter adapter component operates synchronously through a linkage mechanism, causing the triangular pressure block to internally tighten the inner ring of the bearing, forming a stable fixation in both the inner and outer directions. This clamping mechanism not only ensures precise positioning during the inspection process, but its unique reset gear and arc-shaped rack meshing design also automatically triggers the release program when the turntable rotates to the unloading station, achieving intelligent linkage between clamping and release actions, perfectly matching the inspection cycle.
[0020] 2. This invention uses an adjustable screening component to pre-screen bearings by thickness, separating defective products in advance. During the inspection process, an adaptive clamping mechanism flexibly fixes bearings of different sizes, avoiding surface damage that may be caused by rigid clamping. Finally, a robotic arm performs precise sorting based on the inspection results. This grading process forms a complete quality control closed loop, with seamless connection between each link through mechanical linkage, ensuring both processing efficiency and embodying the concept of flexible product handling.
[0021] 3. This invention organically integrates the energy storage characteristics of a spiral spring, the reset characteristics of a torsion spring, and the transmission characteristics of a gear and rack to construct a self-contained energy circulation system. During the clamping process, the spiral spring stores potential energy; during the release phase, the stored energy is released in an orderly manner through the meshing of the gear and rack, driving the clamping mechanism to reset. This design not only reduces dependence on external power sources but also achieves timing control of complex actions through purely mechanical means. The motion logic between each actuator is highly coordinated, effectively improving detection efficiency. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] A bearing testing device with adaptability, such as Figure 1 - Figure 11 As shown, it includes a testing platform 1, a feeding channel 5, and a discharging channel 6. A testing robotic arm 8 is provided on the top surface of the testing platform 1, and a discharging robotic arm 7 is provided above the discharging channel 6. It also includes an outer diameter adapter component 2, which is used to adapt bearings of different outer diameters to be fixed for testing; and an inner diameter adapter component 3, which is used to adapt bearings of different inner diameters to be fixed for testing.
[0041] The screening assembly 4 is used to screen bearings of different thicknesses; the outer diameter adaptation assembly 2 includes a turntable 21, which is located inside the detection table 1 and rotatably connected to the detection table 1. An adaptation table 22 is fixedly connected to the inner side of the turntable 21, and a turntable 23 is rotatably connected to the inner side of the adaptation table 22. A transmission groove 24 is provided on the top surface of the turntable 23. A transmission rod 25 is inserted into the inner side of the transmission groove 24. A telescopic column 27 is inserted into and slidably connected to the top of the transmission rod 25. An adaptation clamp 28 is fixedly connected to the top of the telescopic column 27; the inner diameter adaptation assembly 3 includes a transmission groove 31, which is opened on the top surface of the turntable 23. A transmission rod 32 is inserted into the inner side of the transmission groove 31. A lifting plate 29 is slidably connected to the inner side of the adapter platform 22. A limiting groove 210 is formed on the bottom surface of the lifting plate 29. A limiting piece 211 is fixedly connected to the surface of the telescopic column 27. The limiting piece 211 is located in the limiting groove 210. The lifting plate 29 is located between the limiting piece 211 and the adapter clamping block 28. A reset gear 212 is fixedly connected to the bottom surface of the turntable 23. A rotating shaft 213 is fixedly connected to the bottom surface of the reset gear 212. The rotating shaft 213 is rotatably connected to the turntable 21. A spiral spring 214 is fixedly connected to the surface of the rotating shaft 213. The end of the spiral spring 214 away from the rotating shaft 213 is fixedly connected to the inner wall of the turntable 21. When the robotic arm 8 descends carrying the pressure assembly and applies downward pressure to the bearing, this force is transmitted directly through the bearing body to the multiple adapter clamps 28 that are already in contact with the bottom surface of the bearing. This forces the adapter clamps 28, the telescopic column 27 fixedly connected to them, and the limiting plate 211 fixed to the surface of the telescopic column 27 to move downward together. Since the limiting plate 211 is nested in the limiting groove 210 opened on the bottom surface of the lifting plate 29, the downward movement of the limiting plate 211 will synchronously drive the entire lifting plate 29 to overcome resistance and slide downward along the inner wall of the adapter platform 22. The downward movement of the lifting plate 29 creates the necessary space for the operation of the mechanism below. At the same time, the servo motor 225 starts, and its output end drives the transmission gear 223 to rotate through the reduction gear 224, thereby driving the turntable 21 and its internal adapter platform 22 and turntable 23 to rotate together inside the detection table 1. The rotation of the turntable 21 causes the arc-shaped notch 222 on its side to sweep across the protrusion 220 and arc-shaped rack 221 fixedly installed on the inner side of the inspection table 1.
[0042] Both the turntable 21 and the adapter platform 22 have arc-shaped notches 222 on their sides. A baffle 215 is fixedly connected to the side of the turntable 23. A support rod 216 is fixedly connected inside the arc-shaped notch 222 of the adapter platform 22. A hook 217 passes through and is hinged to the support rod 216. A torsion spring 218 is fixedly connected between the hook 217 and the support rod 216. A triangular block 219 is fixedly connected to the surface of the end of the hook 217 away from the baffle 215. A protrusion 220 and an arc-shaped rack 221 are fixedly connected to the inner side of the detection platform 1. The height of the protrusion 220 and the arc-shaped rack 221 is the same as the height of the arc-shaped notch 222, and the protrusion 220 and the arc-shaped rack 221 are located inside the arc-shaped notch 222. A transmission gear 223 is installed at the bottom of the turntable 21, and a servo motor 225 is installed on the bottom surface of the detection table 1. The output end of the servo motor 225 passes through the detection table 1 and is connected to a reduction gear 224, which meshes with the transmission gear 223. A transmission rod 25 passes through the telescopic column 27 and is inserted into the adapter clamp 28. A return spring 26 is sleeved on the outside of the transmission rod 25. One end of the return spring 26 is fixedly connected to the surface of the transmission rod 25, and the other end is fixedly connected to the bottom surface of the telescopic column 27. The rotation of the turntable 23 causes the transmission groove 24 and the transmission groove 31 on its top surface to drive the transmission rod 25 and the transmission rod 32 inside them to move, respectively. For the outer diameter adapter assembly 2, the movement of the transmission rod 25 within the transmission groove 24 is converted into radial displacement. However, since the telescopic column 27 is pressed down and limited by the lifting plate 29 through the limiting piece 211, the radial movement of the transmission rod 25 will overcome the tension of the return spring 26, pushing the telescopic column 27 and the adapter clamp 28 to radially tighten towards the outer ring of the bearing, thereby tightly fitting and clamping the outer ring of the bearing. The magnitude of its clamping force is related to the displacement of the transmission rod 25, thus adapting to different outer diameter sizes. During the rotation of the turntable 21, the baffle 215 fixed to the side of the turntable 23 will enter the arc-shaped notch 222 area on the side of the adapter platform 22. When the baffle 215 contacts the hook 217 fixed to the support rod 216 inside the arc-shaped notch 222, it will squeeze the triangular block 219 at the end of the hook 217, causing the hook 217 to overcome the elastic force of the torsion spring 218 and rotate around the support rod 216, thereby clearing the path and allowing the baffle 215 to pass. When the turntable 21 rotates to the predetermined angle, after the baffle 215 passes the hook 217, the hook 217 quickly resets under the action of the torsion spring 218 and locks the back of the baffle 215. At this time, the transmission mechanism at the bottom of the turntable 21 controls it to stop rotating. The engagement between the hook 217 and the baffle 215 locks the turntable 23 and the adapter platform 22, maintaining the clamping state of the outer diameter clamping assembly.
[0043] The inner diameter adapter component 3 also includes an arc-shaped block 33. The bottom surface of the arc-shaped block 33 is fixedly connected to the top end of the transmission rod 32. A hinge rod 34 is inserted into and hinged to the inner side of the arc-shaped block 33. A triangular pressure block 35 is fixedly connected to the top end of the hinge rod 34. A torsion spring 36 is fixedly connected between the hinge rod 34 and the arc-shaped block 33. There are three sets of arc-shaped blocks 33, and an elastic expansion ring 37 passes through each pair of arc-shaped blocks 33. Almost simultaneously with the outer diameter being fixed, the inner diameter adapter component 3 also begins to work: the rotation of the turntable 23 causes the transmission groove 31 on its top surface to drive the transmission rod 32 inserted therein to produce radial movement. The arc-shaped block 33 at the top end of the transmission rod 32 moves radially accordingly. The three sets of arc-shaped blocks 33 are linked together through the elastic expansion ring 37 to form a retractable ring structure. The radial movement of the arc-shaped block 33 causes its hinged rod 34 to swing, forcing the triangular pressure block 35 at the top of the hinged rod 34 to contract toward the center of the bearing inner ring or expand outward to fit the inner ring wall. During this process, the torsion spring 36 connecting the hinged rod 34 and the arc-shaped block 33 provides a continuous clamping force to ensure that the triangular pressure block 35 can firmly clamp the bearing inner ring and complete the adaptive fixation of the inner diameter.
[0044] The screening component 4 includes a secondary discharge port 41, which is fixedly connected to the feeding channel 5. An arc-shaped rod 42 is fixedly connected to the inner side of the feeding channel 5. A threaded handle 43 is threaded through and threadedly connected to the inner side of the arc-shaped rod 42. An arc-shaped stop bar 44 is rotatably connected to the bottom of the threaded handle 43. The arc-shaped stop bar 44 is slidably connected to the inner side of the feeding channel 5. A graduated groove 45 is provided on the inner side of the feeding channel 5. This device, by integrating the outer diameter adapter component 2, the inner diameter adapter component 3, and the screening component 4, achieves rapid fixing, detection, and classification of bearings of different sizes. The entire workflow begins with the bearing to be inspected entering the inspection area through the feeding channel 5. At this time, the screening component 4 first performs pre-sorting: by rotating the threaded handle 43, the height position of the arc-shaped baffle 44 inside the feeding channel 5 is adjusted. The operator can accurately set the thickness threshold according to the scale groove 45 opened inside the feeding channel 5. When the bearing rolls through the feeding channel 5, if its thickness exceeds the set value, it will be intercepted by the arc-shaped baffle 44 and guided to the secondary discharge port 41 for discharge. The bearing with qualified thickness can pass smoothly through the arc-shaped baffle 44 and continue to move forward, and finally enter the center of the turntable 23 on the inspection table 1 to wait for inspection.
[0045] The bearing inspection device with adaptation function of the present invention, when in use, integrates an outer diameter adaptation component 2, an inner diameter adaptation component 3, and a screening component 4 to achieve rapid fixing, inspection, and classification of bearings of different sizes. The entire workflow begins with the bearing to be inspected entering the inspection area through the feeding channel 5. At this time, the screening component 4 first performs pre-sorting: by rotating the threaded handle 43, the height position of the arc-shaped baffle 44 inside the feeding channel 5 is adjusted. The operator can accurately set the thickness threshold according to the scale groove 45 opened on the inner side of the feeding channel 5. When the bearing rolls through the feeding channel 5, if its thickness exceeds the set value, it will be intercepted by the arc-shaped baffle 44 and guided to the secondary discharge port 41 for discharge. The bearing with qualified thickness can smoothly pass through the arc-shaped baffle 44 and continue to move forward, and finally enter the waiting inspection area in the center of the turntable 23 on the inspection table 1. The inspection robotic arm 8 on the top of the inspection table 1 then starts to work. This robotic arm is not only responsible for performing multiple index inspections on the bearing, but its end can also be equipped with a pressure component and a detection component. The pressure component can controllably apply a vertical downward pressure to the bearing. When the robotic arm 8 descends carrying the pressure assembly and applies downward pressure to the bearing, this force is transmitted directly through the bearing body to the multiple adapter clamps 28 that are already in contact with the bottom surface of the bearing. This forces the adapter clamps 28, the telescopic column 27 fixedly connected to them, and the limiting plate 211 fixed to the surface of the telescopic column 27 to move downward together. Since the limiting plate 211 is nested in the limiting groove 210 opened on the bottom surface of the lifting plate 29, the downward movement of the limiting plate 211 will synchronously drive the entire lifting plate 29 to overcome resistance and slide downward along the inner wall of the adapter platform 22. The downward movement of the lifting plate 29 creates the necessary space for the operation of the mechanism below. At the same time, the servo motor 225 starts, and its output end drives the transmission gear 223 to rotate through the reduction gear 224, thereby driving the turntable 21 and its internal adapter platform 22 and turntable 23 to rotate together inside the detection table 1. The rotation of the turntable 21 causes the arc-shaped notch 222 on its side to sweep across the protrusion 220 and arc-shaped rack 221 fixedly installed on the inner side of the inspection table 1. The rotation of the turntable 23 causes the transmission groove 1 24 and transmission groove 2 31 on its top surface to drive the transmission rod 1 25 and transmission rod 2 32 inside them to move, respectively. For the outer diameter adapter assembly 2, the movement of transmission rod 1 25 in transmission groove 1 24 is converted into radial displacement. However, since the telescopic column 27 has been pressed down and limited by the lifting plate 29 through the limiting piece 211, the radial movement of transmission rod 1 25 will overcome the tension of the return spring 26, pushing the telescopic column 27 and the adapter clamp 28 to radially tighten towards the outer ring of the bearing, thereby tightly fitting and clamping the outer ring of the bearing. The magnitude of its clamping force is related to the displacement of transmission rod 1 25, thus adapting to different outer diameter sizes.During the rotation of the turntable 21, the baffle 215 fixed to the side of the turntable 23 enters the arc-shaped notch 222 area on the side of the adapter platform 22. When the baffle 215 contacts the hook 217 fixed to the support rod 216 inside the arc-shaped notch 222, it will squeeze the triangular block 219 at the end of the hook 217, causing the hook 217 to overcome the elastic force of the torsion spring 218 and rotate around the support rod 216, thus clearing the path and allowing the baffle 215 to pass. When the turntable 21 rotates to a predetermined angle, after the baffle 215 passes the hook 217, the hook 217 quickly resets under the action of the torsion spring 218 and locks the back of the baffle 215. At this time, the transmission mechanism at the bottom of the turntable 21 controls it to stop rotating. The engagement between the hook 217 and the baffle 215 locks the turntable 23 and the adapter platform 22, maintaining the clamping state of the outer diameter clamping assembly. Almost simultaneously with the outer diameter being fixed, the inner diameter adaptation component 3 also begins to operate: the rotation of the turntable 23 causes the transmission groove 31 on its top surface to drive the transmission rod 32 inserted therein to generate radial movement. The arc-shaped block 33 at the top of the transmission rod 32 moves radially accordingly. The three sets of arc-shaped blocks 33 are linked together through the elastic expansion ring 37 to form a retractable ring structure. The radial movement of the arc-shaped block 33 causes its hinged hinge rod 34 to swing, forcing the triangular pressure block 35 at the top of the hinge rod 34 to contract towards the center of the bearing inner ring or expand outward to fit against the inner ring wall. During this process, the torsion spring 36 connecting the hinge rod 34 and the arc-shaped block 33 provides continuous clamping force, ensuring that the triangular pressure block 35 can firmly clamp the bearing inner ring, completing the adaptive fixation of the inner diameter. At this point, the bearing is reliably fixed from both the inner and outer diameters. The sensors on the inspection robot arm 8 can then perform precise dimensional measurements, appearance defect detection, and clearance measurement on the fixed bearing. After the inspection is completed, the servo motor 225 restarts, driving the turntable 21 to continue rotating to the unloading channel 6. When the turntable 21 rotates to the unloading channel 6, a crucial reset process begins: the reset gear 212, fixed to the bottom of the turntable 23, engages with the arc-shaped rack 221 fixedly mounted on the inner side of the inspection table 1. As the turntable 21 continues to move in the unloading direction, the reset gear 212 will move relative to the stationary arc-shaped rack 221, forcing the reset gear 212 to rotate. The rotation of the reset gear 212 directly drives the turntable 23 to rotate relative to the turntable 21 and the adapter table 22 via the rotating shaft 213. This rotation process causes the transmission groove 24 and transmission groove 31 on the top surface of the turntable 23 to drive the transmission rod 25 and transmission rod 32 to move in opposite directions: transmission rod 25 quickly retracts radially with the help of the return spring 26, causing the adapter clamp 28 to loosen the outer ring of the bearing; similarly, transmission rod 32 also retracts radially, causing the triangular pressure block 35 to loosen the inner ring of the bearing through the arc block 33 and the hinge rod 34, thereby completing the complete reset of the clamping mechanism.Meanwhile, as the turntable 21 rotates to the unloading channel 6, the protrusion 220 fixed on the inspection table 1 enters the arc-shaped notch 222 on the side of the turntable 21 and directly abuts against the inclined surface of the triangular block 219 on the hook 217. This interaction force forces the hook 217 to overcome the elastic force of the torsion spring 218 and rotate around the support rod 216 again, thereby causing the hook of the hook 217 to disengage from the limit of the stop plate 215, releasing the mechanical locking state and preparing for the next work cycle. After the fixed state is completely released, the inspection robot arm 8 picks up the bearing that has been inspected and rises up. Based on the inspection results, the system determines its category and then transfers the bearing to the working range of the unloading robot arm 7. The unloading robot arm 7 finally places the bearing into the corresponding qualified or unqualified unloading channel 6, completing the entire inspection cycle. The device combines mechanical linkage with elastic elements, and relies on the downward pressure of the detection robotic arm 8 as the start signal, as well as the meshing of the reset gear 212 and the arc rack 221 to achieve automatic reset, thus realizing efficient, automatic adaptation and accurate detection of bearings of multiple sizes.
