Description

Technical Field

[0001] The present invention relates to the technical field of bearing ring detection, and in particular to a device and method for detecting the states of inner and outer rings of a bearing ring. Background Art

[0002] Bearing rings are annular components of radial rolling bearings with one or more raceways, consisting of an outer ring and an inner ring. Bearing ring production typically involves forging, heat treatment, and grinding. Overheating, internal cracking, and the formation of a network of carbides during processing can reduce the ring's toughness and strength. Therefore, the bearing ring production line also includes a step for inspecting the condition of both the inner and outer rings.

[0003] The condition inspection of bearing rings usually involves first passing a large number of bearing rings through automatic sorting equipment such as a vibrating plate, and then transporting the bearing rings one by one to the inspection equipment, and then inspecting them through visual inspection, eddy current inspection, detection inspection, etc.

[0004] Because loading devices are typically customized based on the specific dimensions of bearing rings—for example, the track of the vibrating plate must match the outer diameter of the bearing ring—existing bearing ring inspection devices lack versatility. Changing the type of bearing ring to be inspected requires replacing the entire device, reducing efficiency. Furthermore, bearing rings must occupy two separate inspection lines, one for the inner and outer rings. In some workshops, the inner and outer rings are mixed together, requiring manual sorting, increasing production costs. Summary of the Invention

[0024] S1. Place a mixed number of inner ring bodies and outer ring bodies on the vibrating plate body.

After passing through the second screening plate and the first screening plate, the inner ring bodies and outer ring bodies form a conveying team and enter the linear feeding track.

[0025] S2. The plurality of inner rings and the plurality of outer rings are moved along the linear feeding track by the second driving assembly. During the movement, the plurality of inner rings and the plurality of outer rings are screened by the screening assembly so that the conveying team is divided into a first branch consisting entirely of inner rings and a second branch consisting entirely of outer rings, and the conveying team is stopped by the stopping assembly.

[0027] The present invention has the following beneficial effects:

[0028] 1. This device and method for detecting the inner and outer ring status of bearing rings features an adjustable width for each screening track in the feeding mechanism, allowing adjustments based on the specific diameter of the bearing ring, improving the versatility of the detection device. Furthermore, in workshops where inner and outer rings are mixed, manual screening is eliminated, eliminating the need for separate inspection lines and the need for two sets of inspection equipment. A screening assembly is installed on the feeding mechanism, which uses an arched track to separate the inner and outer rings into two upper and lower conveyor lines. Ultimately, a single inner and outer ring combination lands on the conveyor mechanism for simultaneous conveying and inspection. During visual inspection, a linear array camera installed on the second horizontal conveyor mechanism can simultaneously capture images of the inner and outer rings, significantly improving inspection efficiency.

[0029] 2. This device and method for detecting the inner and outer ring status of bearing rings also takes into account the various placements of inner and outer rings of varying sizes during loading onto the vibrating plate. Multiple screening passes are implemented. First, the second screening plate removes inner and outer rings that are stacked, vertically, or tilted, and re-conveys them, forming a single-layer conveyor line. The first screening plate then removes them, forming a conveyor line consisting of several columns of single inner and outer rings. Finally, an arched track, which provides both height adjustment and horizontal position adjustment, forms a conveyor line consisting of a single outer ring on the upper side and a single inner ring on the lower side, with the diameters of the two conveyor lines aligned. This ensures that if a portion of the inner ring is encased within the outer ring, the inner ring falls into the lower conveyor line.

[0030] 3. The device and method for detecting the status of the inner and outer rings of the bearing ring also take into account that the inner and outer rings of some bearings, such as tapered bearings, are not regular circular rings and have a distinction between the front and back sides. A correction mechanism is set up, which uses a robotic arm to first hinge the position of the inner or outer ring of the shaft in the horizontal plane, and then uses probes that are respectively adapted to the difference in inner or outer diameters of the front and back sides to perform detection. If the reverse side is detected, it will be turned over. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1

[0045] The bearing ring 100 is divided into two rings, an inner ring body 110 and an outer ring body 120. Usually, the feeding mechanism 200 needs to be customized according to the size of the rings in order to finally arrange a long line of single rings. The rings are then transported one by one through the conveying mechanism 300 to the inspection mechanism 400 for inspection. In order to improve the versatility of the feeding mechanism 200 and to simultaneously perform the feeding and inspection process on the inner ring body 110 and the outer ring body 120 at one time, the first embodiment is proposed;

[0046] See also Figures 1-9 The device for detecting the status of the inner and outer rings of a bearing ring includes a feeding mechanism 200, a conveying mechanism 300 and a detection mechanism 400. The feeding mechanism 200 includes a vibration plate body 210 for carrying the bearing ring 100. The bearing ring 100 includes an inner ring body 110 and an outer ring body 120.

[0047] The vibrating plate body 210 is provided with a spiral feeding track 220 and a linear feeding track 230. The head end of the linear feeding track 230 is connected to the tail end of the spiral feeding track 220. The spiral feeding track 220 is provided with a first driving assembly 240. The linear feeding track 230 is provided with a second driving assembly 250 and a screening assembly 260.

[0048] The conveying mechanism 300 includes a first horizontal conveying device 310 and a pallet 320. The pallet 320 is located below the tail end of the linear loading track 230. The detection mechanism 400 includes several second horizontal conveying devices 410 located above the pallet 320. Linear array cameras 420 are provided on each of the second horizontal conveying devices 410.

[0049] The first drive assembly 240 operates to allow the inner ring 110 and the outer ring 120 to pass through the spiral loading track 220 and enter the linear loading track 230. The second drive assembly 250 then operates to allow the inner ring 110 and the outer ring 120 to be screened by the screening assembly 260 and then fall separately onto the support plate 320 for transportation and inspection.

[0050] The first driving assembly 240 includes a chassis 241 disposed on the top of the vibration plate body 210, the chassis 241 is connected to the spiral feeding track 220, a vibration plate 242 is disposed on the chassis 241, a pulse electromagnet 243 is disposed in the vibration plate body 210, and a plurality of spring plates 244 are disposed on the vibration plate 242;

[0051] A second screening plate 280 is further provided on the spiral feeding track 220, and a stop assembly 270 is further provided on the linear feeding track 230. The stop assembly 270 includes two chutes 271 provided on the linear feeding track 230. The two chutes 271 are respectively located in the first channel and the second channel.

[0052] Baffles 272 are slidably disposed in the two sliding grooves 271 . Two cylinders 273 are disposed on the first side plate 232 . The piston rods of the two cylinders 273 are connected to the two baffles 272 respectively.

[0053] In this embodiment, the top of the vibrating plate body 210 is a semi-enclosed space formed by the bottom of the base plate 241 and the spiral feed track 220. The inner ring 110 and outer ring 120 can be mixed and placed on the base plate 241. The spiral feed track 220 is an upwardly expanding conical spiral that facilitates track screening. Several shock-absorbing pads 290 installed at the bottom of the vibrating plate body 210 provide shock absorption.

[0054] The pulse electromagnet 243 generates high-frequency periodic magnetic attraction, which causes a plurality of spring plates 244 to vibrate. The ends of the spring plates 244 are bolted to the inner wall of the vibrating plate body 210 and the vibrating plate 242, respectively. The tilted spring plates 244 drive the spiral feeding track 220 to perform torsional vibration around its vertical axis, ultimately causing the inner ring 110 and the outer ring 120 to rise along the spiral feeding track 220 to the rear end of the spiral feeding track 220.

[0055] The leading end, or left end, of the linear feed track 230 connects to the trailing end of the spiral feed track 220. During the spiral ascent of the inner and outer ring bodies 110, 120, they may intermingle in various positions. However, the first screening occurs when the inner and outer ring bodies 110, 120 pass through the second screening plate 280. As shown in the figure, the left end of the second screening plate 280 is adjacent to the bottom wall of the spiral feed track 220, while the right end of the second screening plate 280 is adjacent to the top of the spiral feed track 220. Furthermore, the first screening plate 261 to the right of the second screening plate 280 also serves a screening function. Through the second screening plate 280 and the first screening plate 261, the inner ring body 110 and the outer ring body 120 will be transported to the right along the straight feeding track 230 in the form of a single column, and a total of several columns form a row, while the excess inner ring body 110 and outer ring body 120 will fall to the bottom plate 241 through the inner side of the spiral feeding track 220 and be spirally transported again.

[0056] The inner ring 110 and the outer ring 120 are then diverted by the screening assembly 260 and stopped by the stopping assembly 270, and finally fall onto the support plate 320, one on the left and one on the right, respectively. The support plate 320 is then moved forward by the first horizontal conveying device 310 to the detection mechanism 400 for status detection.

[0057] The inspection mechanism 400, driven by a second horizontal conveyor 410, moves a line scan camera 420 to take images, and then visually analyzes the inner and outer ring bodies 110, 120 for defects. Multiple line scan cameras 420 are installed at different angles to capture images from different angles of the inner and outer ring bodies 110, 120. The support plate 320 can be made of a transparent material, allowing the inspection mechanism 400 to also be positioned on its underside to capture images of the lower ends of the inner and outer ring bodies 110, 120.

[0058] After the final inspection is completed, multiple silos and rejection devices can be set in front of the first horizontal conveying device 310 to screen the inner ring body 110 and the outer ring body 120 according to good products and different defects.

[0059] It should be noted that the second drive assembly 250 moves the bearing ring 100 on the linear loading track 230 to the right through operation. Its structural principle is the same as that of the first drive assembly 240. The difference is that the direction of the generated torsional vibration is to the right. Its specific structure will not be repeated here.

[0060] The first horizontal conveying device 310 and the second horizontal conveying device 410 may be screw conveying devices, specifically, a motor drives a screw to rotate, which in turn drives a nut to move along the guide rail. Specifically, in the conveying mechanism 300, the support plate 320 is mounted on the nut. In the detection mechanism 400, the line array camera 420 is mounted on the nut.

[0061] The working principle of the line array camera 420 belongs to the existing technology and will not be described in detail. In addition, probe detection, eddy current detection, etc. can also be set, which are all conventional technical means.

[0062] The structural positions of the vibration plate body 210, the second driving assembly 250, the first horizontal conveying device 310, the second horizontal conveying device 410 and the first vertical conveying device 510 are fixed, and the workbench or bracket is not shown in the figure.

[0063] Example 2

[0064] In order to achieve the screening of the inner ring body 110 and the outer ring body 120, and to facilitate adjustment of the screening track according to the specific diameters of the inner ring body 110 and the outer ring body 120, a second embodiment is proposed;

[0065] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 2-Figure 8 The linear feeding track 230 includes a straight track 231 and a first side plate 232 . The screening assembly 260 includes a first screening plate 261 disposed on the straight track 231 . The distance between the first screening plate 261 and the first side plate 232 is equal to the diameter of the outer ring 120 .

[0066] The straight track 231 is further provided with a first screening track 262 and a second screening track 263. The second screening track 263 is provided with a second side plate 264. The distance between the first screening track 262 and the second screening track 263 is equal to the diameter of the inner ring body 110. The second side plate 264 is connected to the first screening plate 261.

[0067] The first screening track 262, the second screening track 263 and the second side plate 264 are all arched. After the inner ring body 110 and the outer ring body 120 are screened, the outer ring body 120 falls onto the supporting plate 320 along the first channel formed by the first screening track 262, the second screening track 263, the first side plate 232 and the second side plate 264.

[0068] A ramp 233 is provided at the tail end of the straight track 231. A third side plate 234 is provided on the ramp 233. A fourth side plate 268 is provided on the second screening track 263. The distance between the third side plate 234 and the fourth side plate 268 is equal to the diameter of the inner ring body 110. The inner ring body 110 falls onto the supporting plate 320 along the second channel formed by the ramp 233, the third side plate 234 and the fourth side plate 268.

[0069] The first screening plate 261 and the second screening track 263 are both slidably connected to the straight track 231 , and the second side plate 264 is slidably connected to the second screening track 263 ;

[0070] The first screening plate 261 is connected to the first side plate 232 via a first bolt adjustment device 265 , the second screening track 263 is connected to the straight track 231 via a second bolt adjustment device 266 , and the second side plate 264 is connected to the second screening track 263 via a third bolt adjustment device 267 .

[0071] In this embodiment, after passing through the second screening plate 280 , the inner ring body 110 or the outer ring body 120 is a single layer and will not be stacked together. After passing through the first screening plate 261 , it will become a row consisting of a single inner ring body 110 or outer ring body 120 .

[0072] The first and second screening tracks 262 and 263 then form a lower channel. As shown in the figure, the left ends of the first and second screening tracks 262 and 263 not only increase in height from left to right but also decrease in spacing from left to right. This decreasing spacing allows the inner ring 110 to continue to be transported rightward along the lower channel after adjusting its front-to-back position. The outer ring 120, meanwhile, is transported along the arched path, first diagonally upward and then horizontally to the right, due to the increasing height of the first and second screening tracks 262 and 263. Furthermore, during this process, the left-right diameters of the upper outer ring 120 and the lower inner ring 110 are aligned in the same vertical plane. In the unlikely event that the inner ring 110 were to become nested within the outer ring 120, the inner ring 110 would naturally fall to the lower side. Due to the vibration process and the height restriction of the first screening track 262, the inner ring 110 would not overlap.

[0073] In addition, the first screening plate 261 is slidably mounted on the straight track 231 and is conveniently adjusted through the first bolt adjustment device 265. The second screening track 263 is slidably mounted on the straight track 231 and is conveniently adjusted through the second bolt adjustment device 266. The second side plate 264 is slidably mounted on the second screening track 263 and is conveniently adjusted through the third bolt adjustment device 267.

[0074] Taking the first bolt adjustment device 265 as an example, a bolt is threadedly connected to the first screen plate 261 and the first side plate 232. After the position of the first screen plate 261 is adjusted forward and backward, the position of the first screen plate 261 can be fixed by a locking nut.

[0075] When the outer ring body 120 team on the upper side and the inner ring body 110 team on the lower side reach the stop assembly 270 to the right, they are stopped by two baffles 272. The cylinder 273 controls the interval release once, so that an inner ring body 110 and an outer ring body 120 can be transported to the right and fall on the left and right sides of the support plate 320 respectively along a channel of the ramp 233 and a channel composed of the first screening track 262 and the second screening track 263.

[0076] Example 3

[0077] Considering that the inner ring body 110 and the outer ring body 120 of some bearings have front and back sides, there will be errors in the front and back sides during visual inspection or detection. In this case, the inner ring body 110 and the outer ring body 120 need to be turned over so that the front end faces upward. For this purpose, the third embodiment is proposed;

[0078] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1-11 The inner ring body 110 is a tapered bearing component. The inner ring body 110 includes an inner ring positive end 111 and an inner ring reverse end 112. The outer ring body 120 includes an outer ring positive end 121 and an outer ring reverse end 122. The inner diameter of the outer ring body 120 gradually increases from the outer ring positive end 121 to the outer ring reverse end 122.

[0079] Two correction mechanisms 500 are further provided between the linear feeding track 230 and the detection mechanism 400. The two correction mechanisms 500 are respectively used to correct the inner ring body 110 and the outer ring body 120 so that the inner ring positive end 111 of the inner ring body 110 and the outer ring positive end 121 of the outer ring body 120 are upward.

[0080] The correction mechanism 500 includes a first vertical conveying device 510, on which a lifting base 520 is provided. A turntable 530 is rotatably provided on the lifting base 520, on which a robotic arm 540 is provided. A motor 550 is also provided on the lifting base 520, and an output shaft of the motor 550 is connected to the turntable 530.

[0081] The correction mechanism 500 also includes a second vertical conveying device 560 arranged on the lifting seat 520. The second vertical conveying device 560 is connected to an electric three-jaw chuck 580 through a cantilever 570. The electric three-jaw chuck 580 includes three jaws 581. The three jaws 581 are each provided with a probe 590. The three probes 590 are arranged in a circle along the outer diameter of the inner ring body 110 or the inner diameter of the outer ring body 120.

[0082] In this embodiment: If the bearing ring 100 is a component of a tapered bearing, Figure 1 The structural features of the inner ring 110 and outer ring 120 are shown. The side with the larger outer diameter is the front side of the inner ring 110, and the side with the smaller inner diameter is the front side of the outer ring 120. This front and back are actually determined manually, but it is necessary to keep the inner ring positive end 111 and the outer ring positive end 121 fixed to one side. The support plate 320, carrying the inner ring 110 and the outer ring 120, pauses when it reaches the correction mechanism 500.

[0083] In the left calibration mechanism 500, the first vertical conveying device 510 drives the lifting seat 520 and the mechanical arm 540 to move downward, and then the mechanical arm 540 operates to clamp the inner ring body 110. At the same time, it also plays a role in calibrating the position of the inner ring body 110 on the horizontal plane.

[0084] Then the front and back sides are inspected, and the cantilever 570 and the electric three-jaw chuck 580 are driven downward by the second vertical conveying device 560. As the electric three-jaw chuck 580 is an existing technology, its specific structure is not described in detail. The electric three-jaw chuck 580 is driven by a motor to make the three jaws 581 move radially synchronously, thereby driving the three probes 590 to adjust their positions.

[0085] At this time, the three probes 590 are aligned with the diameter of the inner ring positive end 111 of the inner ring body 110. If the inner ring body 110 is as Figure 10 If the inner ring 110 is placed upside down, the three probes 590 will not touch the object. A sensor can be installed on the probe 590. The sensor can sense that the inner ring 110 is placed upside down. If the probe 590 touches the object, it means that the inner ring 110 is placed correctly.

[0086] For the inner ring body 110 facing upward, the first vertical conveying device 510 drives the robotic arm 540 and the inner ring body 110 to rise, and then the lifting seat 520 drives the turntable 530 and the robotic arm 540 to rotate 180°, and then the first vertical conveying device 510 drives the robotic arm 540 and the inner ring body 110 to fall, and the robotic arm 540 is released to complete the correction.

[0087] In the correction mechanism 500 on the right, similarly, the three probes 590 need to be aligned with the diameter of one side of the outer ring positive end 121 of the outer ring body 120, that is, the thicker diameter. If the three probes 590 do not touch the object when they fall, it means that the outer ring body 120 is placed correctly. If they touch it, it means that the outer ring body 120 is placed upside down.

[0089] See also Figures 1-11 The detection method of the bearing ring inner and outer ring state detection device comprises the following steps:

[0090] S1. Place a mixed number of inner ring bodies 110 and a number of outer ring bodies 120 on the vibration plate main body 210. The first driving assembly 240 is operated to make the inner ring bodies 110 and the outer ring bodies 120 move upward in a spiral along the trajectory of the spiral feeding track 220. After passing through the second screening plate 280 and the first screening plate 261, the inner ring bodies 110 and the outer ring bodies 120 form a conveying team and enter the linear feeding track 230. The conveying team consists of several rows of conveying sequences, each conveying sequence is a single inner ring body 110 or a single outer ring body 120;

[0091] S2. The second driving assembly 250 is operated to move the plurality of inner ring bodies 110 and the plurality of outer ring bodies 120 along the linear feeding track 230. During the movement, the screening assembly 260 screens the inner ring bodies 110 and the outer ring bodies 120, causing the conveying team to be divided into a first branch consisting entirely of the inner ring bodies 110 and a second branch consisting entirely of the outer ring bodies 120, and the second branch is stopped by the stopping assembly 270.

[0092] S3. An inner ring body 110 and an outer ring body 120 are released individually onto the pallet 320 by the stopping component 270, and the first horizontal conveying device 310 is used to transport the inner ring body 110 and the outer ring body 120 to two correction mechanisms 500. After being calibrated by the two correction mechanisms 500, they are transported to several linear array cameras 420 for visual inspection.
