Description

Technical Field

[0002] Thin-walled bearings are a special type of bearings. Thin-walled bearings have an extremely thin bearing section, and also achieve miniaturization and lightness of the product. Thin-walled bearing rings are annular parts of radial rolling bearings with one or more raceways.

[0003] During the processing of thin-walled bearing rings, they need to be inspected. Usually, the inspection methods of the rings include visual inspection, eddy current inspection, detection inspection, etc. Among them, the detection inspection is to send a row of rings to the detection inspection equipment one by one through a conveying device, drive the rings to rotate through a set of fixtures, and at the same time, a set of probes are attached to the inner or outer wall of the ring and raised and lowered, and the probes are used to test whether the dimensions of the inner and outer surfaces of the rings are uniform.

[0004] This detection method usually requires the entire detection line to run intermittently. When one or more rings are sent into one or more detection devices, the device for conveying the rings will pause, and it is necessary to wait until the rings in the detection device are inspected before it can continue to be conveyed, which reduces the efficiency of the thin-walled bearing ring production line.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0045] For example, see Figure 1-Figure 9 A detection device for processing thin-walled bearing rings includes a feeding mechanism 200, a transfer mechanism 300 and a unloading mechanism 500, wherein the transfer mechanism 300 is arranged between the feeding mechanism 200 and the unloading mechanism 500.

[0046] The transfer mechanism 300 includes a disc 310 and a first rotating component 340. A rotating drum 320 is rotatably arranged on the disc 310. A plurality of wing plates 330 are equidistantly arranged circumferentially on the rotating drum 320. Two detection mechanisms 400 are arranged on each of the plurality of wing plates 330. The two detection mechanisms 400 are distributed along the radial direction of the rotating drum 320.

[0047] The detection mechanism 400 includes a bearing assembly 410 and a detection assembly 420. The bearing assembly 410 is used to bear the thin-walled bearing ring 100. The bearing assembly 410 includes a second rotating assembly 413. The detection assembly 420 includes a lifting assembly 421. A plurality of first probes 424 and a plurality of second probes 427 are equidistantly arranged circumferentially on the lifting assembly 421.

[0048] After the feeding mechanism 200 conveys the thin-walled bearing ring 100 to be inspected onto the two supporting components 410, the first rotating component 340 drives the rotating drum 320 to rotate. During the rotation process, the thin-walled bearing ring 100 is driven to rotate by the second rotating component 413, and the lifting component 421 drives a plurality of first probes 424 to descend along the inner wall of the thin-walled bearing ring 100, and drives a plurality of second probes 427 to descend along the outer wall of the thin-walled bearing ring 100, thereby performing dimensional inspection on the inner and outer walls of the thin-walled bearing ring 100.

[0049] The feeding mechanism 200 includes a base 210 , on which a belt conveyor 220 for conveying the thin-walled bearing ring 100 is disposed, and a transport assembly 230 is also disposed on the base 210 .

[0050] The transport assembly 230 includes a first screw conveying device 231 arranged on the base 210, a first movable seat 232 is arranged on the first screw conveying device 231, a second screw conveying device 233 is arranged on the first movable seat 232, a second screw conveying device 233 is arranged on the second movable seat 234, and two robotic arms 235 are arranged on the second movable seat 234.

[0051] The structure of the unloading mechanism 500 is consistent with that of the loading mechanism 200 .

[0052] The first rotating assembly 340 includes a motor 341 disposed in the disc 310 , a first pulley 342 is disposed on the output shaft of the motor 341 , a second pulley 343 is disposed on the rotating drum 320 , and the first pulley 342 is transmission-connected to the second pulley 343 via a belt 344 .

[0053] In this embodiment: First, upstream of the production line, a large number of thin-walled bearing rings 100 are transported backwards by a belt conveyor 220. The belt conveyor 220 can be composed of a conveyor roller, a conveyor belt, and a driving device. As a conventional technical means, its specific structure and working principle are not described in detail.

[0054] When the two thin-walled bearing rings 100 on the rear side are transported to the conveying assembly 230, the second screw conveying device 233 arranged along the upper and lower axes drives the second movable seat 234 and the two robotic arms 235 to descend, and the two robotic arms 235 respectively clamp the two thin-walled bearing rings 100 through operation, and then the second screw conveying device 233 controls the two robotic arms 235 and the two thin-walled bearing rings 100 to rise, and then the first screw conveying device 231 arranged along the front-rear axis direction drives the first movable seat 232 and the second screw conveying device 233, the two robotic arms 235, and the two thin-walled bearing rings 100 to move backward, and at this time, one of the wing plates 330 stays in a position pointing to the front.

[0055] Then, the second screw conveying device 233 drives the two mechanical arms 235 and the two thin-walled bearing rings 100 to descend, and the two mechanical arms 235 release the two thin-walled bearing rings 100, so that the two thin-walled bearing rings 100 fall on the two rotating disks 411. Then, the transport assembly 230 is reset to wait for the next group of thin-walled bearing rings 100 to arrive, and the rotating drum 320 rotates 180° counterclockwise under the drive of the first rotating assembly 340, and the two thin-walled bearing rings 100 are detected during the rotation process. Then, the two thin-walled bearing rings 100 after the detection are completed arrive at the rear side of the disc 310. At this time, the two thin-walled bearing rings 100 are taken down and transported to the downstream of the production line through the unloading mechanism 500 with the same structure as the loading mechanism 200.

[0056] The loading mechanism 200, the transfer mechanism 300 and the unloading mechanism 500 can operate continuously or only stop the conveying for a short time during the process of picking up and putting down the thin-walled bearing ring 100, thereby improving the production efficiency.

[0057] The first screw conveying device 231 and the second screw conveying device 233 can be composed of a driving device, a screw and a nut. The first moving seat 232 is connected to the nut of the first screw conveying device 231. The operation of the first screw conveying device 231 can drive the first moving seat 232 to move forward and backward. The second moving seat 234 is connected to the nut of the second screw conveying device 233. The operation of the second screw conveying device 233 can drive the second moving seat 234 to move up and down.

[0058] The motor 341 drives the first pulley 342 to rotate by running, and the first pulley 342 drives the second pulley 343 and the rotating drum 320 to rotate through the transmission of the belt 344.

[0059] It should be supplemented that, in order to improve the detection efficiency, two inner and outer detection mechanisms 400 are installed on one wing plate 330 along the radial direction of the drum 320, so that two thin-walled bearing rings 100 can be detected at one time. It is also possible to install more than two detection mechanisms 400 on one wing plate 330, and the number of mechanical arms 235 needs to be increased accordingly.

[0060] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 12 The bearing assembly 410 includes a turntable 411 arranged on the wing plate 330, and a clamping assembly 412 is arranged on the turntable 411. The clamping assembly 412 includes two clamps 4121 symmetrically slidably arranged on the turntable 411, and a lifting rod 4122 is slidably arranged on the turntable 411. A connecting seat 4123 is arranged on both clamps 4121.

[0061] The clamping assembly 412 further includes two connecting rods 4124 , one end of the two connecting rods 4124 are movably hinged to the lifting rod 4122 through a hinge shaft, and the other ends of the two connecting rods 4124 are movably hinged to two connecting seats 4123 through a hinge shaft.

[0062] A first guide rod 4125 is disposed on the lifting rod 4122 , and two concentrically disposed first annular guide grooves 350 are provided on the disk 310 . The two first guide rods 4125 are slidably connected to the two first annular guide grooves 350 , respectively.

[0063] The first annular guide groove 350 includes a first horizontal arc segment 351, a second horizontal arc segment 352 and two first connecting segments 353. The depth of the second horizontal arc segment 352 is greater than that of the first horizontal arc segment 351. The two ends of the first horizontal arc segment 351 are connected to the two ends of the second horizontal arc segment 352 through the two first connecting segments 353 respectively.

[0064] In this embodiment, a set of detection mechanisms 400 located outside the disc 310 is taken as an example, and the detection mechanisms 400 are located farther from the center of the disc 310 and the rotating drum 320. When the thin-walled bearing ring 100 falls on the rotating disc 411, the two clamps 4121 are far away from each other and do not clamp the thin-walled bearing ring 100.

[0065] During the counterclockwise rotation of the drum 320, the first guide rod 4125 moves in a counterclockwise circular motion along with the turntable 411. The first guide rod 4125 passes through a first connecting section 353 on a slope and then reaches the second horizontal arc section 352. During this process, the first guide rod 4125 descends, and the lifting rod 4122 descends accordingly. The lifting rod 4122 descends and drives the two clamps 4121 to move closer to each other through the transmission of the two connecting rods 4124 and the two connecting seats 4123 to clamp and fix the thin-walled bearing ring 100. When the drum 320 continues to rotate counterclockwise until it reaches the unloading mechanism 500, the two first guide rods 4125 pass through the first connecting section 353 on the rear side and rise to the first horizontal arc section 351. At this time, the lifting rod 4122 rises so that the two clamps 4121 are separated from the loosened thin-walled bearing ring 100.

[0066] The same is true for the detection mechanism 400 located near the inner side of the disk 310. Fig.12 As shown, the first annular guide groove 350 of the outer ring is concentrically arranged with the first annular guide groove 350 of the inner ring. When the first guide rod 4125 of the inner ring reaches the second horizontal arc segment 352 of the inner ring, the first guide rod 4125 of the outer ring also reaches the second horizontal arc segment 352 of the outer ring synchronously.

[0067] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-Figure 11 The second rotating assembly 413 includes a gear 4131 disposed on the rotating disk 411 . Two arc-shaped racks 360 are disposed on the disk 310 . The two gears 4131 are respectively meshed with the two arc-shaped racks 360 .

[0068] The rotating disk 411 is provided with an arc block 4132 , and the disk 310 is provided with two concentrically arranged slide grooves 370 , and the two arc blocks 4132 are slidably connected in the two slide grooves 370 , respectively.

[0069] The slide groove 370 includes a limiting section 371 , a non-limiting section 372 and a second connecting section 373 . Two ends of the limiting section 371 are connected to two ends of the non-limiting section 372 through two second connecting sections 373 .

[0070] In this embodiment, the detection mechanism 400 of the outer ring is also used as an example. When the rotating disk 411 is in the first horizontal arc segment 351, the arc block 4132 slides in the matching arc limit segment 371. At this time, the arc block 4132 is limited and cannot rotate. When the rotating disk 411 is in the first connecting segment 353 and the second horizontal arc segment 352, the arc block 4132 comes to the second connecting segment 373 with a larger diameter and the non-limiting segment 372. At this time, the arc block 4132 is no longer limited, and the rotating disk 411 and the thin-walled bearing ring 100 thereon can rotate.

[0071] When the turntable 411 reaches the first connecting section 353 and the second horizontal arc section 352, the gear 4131 contacts and engages with the arc rack 360. When the turntable 411 makes a counterclockwise circular motion along the second horizontal arc section 352, the gear 4131 is driven to rotate, thereby driving the turntable 411 and the thin-walled bearing ring 100 to rotate.

[0072] The same is true for a set of detection mechanisms 400 of the inner ring. The arc-shaped rack 360 of the inner ring and the arc-shaped rack 360 of the outer ring can be set to have the same number of teeth, so that the rotation speeds of the thin-walled bearing rings 100 of the inner and outer rings are consistent.

[0073] Embodiment 4: This embodiment is an improvement on Embodiment 3. For details, please refer to Figure 1-Figure 13 The lifting assembly 421 includes a fixed seat 4211 arranged on the wing plate 330, a lifting seat 4212 is slidably arranged on the fixed seat 4211, a first three-jaw chuck 422 is arranged on the lifting seat 4212, a plurality of first claws 423 are equidistantly arranged circumferentially on the first three-jaw chuck 422, and a plurality of first probes 424 are respectively arranged on the plurality of first claws 423.

[0074] A second three-jaw chuck 425 is also provided on the lifting seat 4212 . A plurality of second clamping claws 426 are equidistantly provided circumferentially on the second three-jaw chuck 425 . A plurality of second probes 427 are respectively provided on the plurality of second clamping claws 426 .

[0075] A second guide rod 4213 is disposed on the lifting seat 4212 , and two concentrically disposed second annular guide grooves 380 are formed on the disk 310 . The two second guide rods 4213 are slidably connected to the two second annular guide grooves 380 , respectively.

[0076] The second annular guide groove 380 includes a third horizontal arc segment 381 and an inclined arc segment 382 .

[0077] In this embodiment: in the detection component 420 located on the upper side of the supporting component 410, when the turntable 411 is in the first horizontal arc segment 351, the second guide rod 4213 slides along the third horizontal arc segment 381. At this time, the second guide rod 4213 and the lifting seat 4212 are on the upper side, so that the first three-jaw chuck 422 and the second three-jaw chuck 425 are on the upper side. At this time, the first probe 424 and the second probe 427 are not in contact with the thin-walled bearing ring 100.

[0078] When the rotating disk 411 reaches the first connecting section 353 and the second horizontal arc section 352, the second guide rod 4213 slides from the third horizontal arc section 381 to the inclined arc section 382. Fig.13As shown, the inclined arc segment 382 is an inclined arc, the rightmost end point of which is located at the lowest position, and there is an inclined transition from the rightmost end point to the front and rear end points.

[0079] When the second guide rod 4213 slides along the inclined arc segment 382, ​​the second guide rod 4213 gradually descends, driving the first three-jaw chuck 422 and the second three-jaw chuck 425 to descend, thereby driving the first probes 424 and the second probes 427 to descend and contact the rotating inner and outer walls of the thin-walled bearing ring 100.

[0080] Corresponding sensors can be installed on the first probe 424 and the second probe 427. When the inner wall and the outer wall of the thin-walled bearing ring 100 are completely consistent in size, the pressure measured by the first probe 424 and the second probe 427 is constant. When the inner wall and the outer wall of the thin-walled bearing ring 100 have uneven positions, the first probe 424 and the second probe 427 can sense it accordingly.

[0081] In addition, the positions of the first probe 424 and the second probe 427 can be adjusted according to the specific size of the thin-walled bearing ring 100. The first three-jaw chuck 422 can be an automatic chuck such as a pneumatic or electric one. The operation of the first three-jaw chuck 422 can drive the three first jaws 423 to move radially synchronously to adjust the positions of the three first probes 424. The second three-jaw chuck 425 is similar, and the second three-jaw chuck 425 is concentric with the first three-jaw chuck 422.

[0082] It should be supplemented that the first guide rod 4125 and the second guide rod 4213 are composed of a round rod and a sphere. The diameter of the sphere is larger than that of the round rod, and the cross-sectional shape of the corresponding guide groove is also consistent with it, which makes the first guide rod 4125 and the second guide rod 4213 slide more smoothly, and the large diameter of the sphere can also play a limiting role.

[0083] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
