Description

Technical Field

[0001] This invention relates to the field of bearing testing technology, and in particular to an automated bearing testing line. Background Technology

[0002] As the core transmission component of various mechanical equipment, the appearance precision and surface quality of bearings directly determine the operational stability, transmission efficiency, and service life of the equipment. If there are defects such as scratches, bumps, missing materials, burrs, or dimensional deviations on the bearing end face, inner ring, or outer ring, it will lead to abnormal assembly clearance and increased rotational resistance. This can cause abnormal noise and vibration in the equipment, or even cause bearing jamming, failure, or even failure of the entire machine. Therefore, after the bearing is produced, a comprehensive and accurate appearance inspection is an indispensable key step in the bearing manufacturing process.

[0003] Existing bearing appearance inspection technologies and equipment still have many shortcomings, making it difficult to meet the needs of large-scale, high-precision production inspection. The inspection dimensions are not comprehensive, and most inspection devices only inspect a single part or a single side of the bearing, such as only inspecting the outer surface of the outer ring or a single end face of the bearing. Defects in the inner wall of the inner ring, the reverse end face of the bearing, etc., are easily missed. It is impossible to achieve full-dimensional appearance coverage inspection of the bearing, resulting in inspection blind spots. Moreover, the inspection methods have a low degree of automation, and some inspection processes rely on manual visual inspection or simple tooling to assist in inspection. Manual judgment is easily affected by subjective factors and visual fatigue, resulting in low inspection accuracy, high rate of missed and false detections, and low inspection efficiency, which is difficult to match the pace of large-scale bearing production. In view of this, this invention is proposed. Summary of the Invention

After clamping, the first cylinder is activated, which drives the support frame at the output end to move, thereby causing the clamping assembly to move the bearing upward. At this time, the top surface of the bearing can be photographed and inspected by the end-face camera. Then, the stepper motor drives the vertical plate to rotate half a revolution, at which point the clamping assembly will cause the bottom of the bearing to face upward, and the bottom surface of the bearing can be photographed and inspected by the end-face camera.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1: Refer to Figures 1-10An automated bearing inspection line includes a feeding bracket 1 and an inspection bracket 2, a feeding conveyor belt 101 disposed on the feeding bracket 1 and an inspection conveyor belt 201 disposed on the inspection bracket 2; and an end face inspection area 3, an outer ring inspection area 4 and an inner ring inspection area 5, which are sequentially disposed on the inspection bracket 2, with the end face inspection area 3 disposed at one end closer to the feeding bracket 1; a support frame 304 is slidably disposed within the end face inspection area 3, and a vertical plate 307 is rotatably disposed on the outer wall of the support frame 304, with a clamping assembly for clamping the bearing 102 on the vertical plate 307; and a discharge plate 205 is disposed at one end of the inspection bracket 2 away from the feeding bracket 1.

[0023] In this embodiment, during use, the bearings 102 are first placed sequentially on the feeding conveyor belt 101, allowing them to enter the inspection conveyor belt 201. The bearings 102 then sequentially pass through the end face inspection area 3, the outer ring inspection area 4, and the inner ring inspection area 5 on the inspection conveyor belt 201. When the bearing 102 enters the end face inspection area 3, the upper end face of the bearing 102 is inspected. After the upper end face inspection is completed, the clamping assembly clamps the bearing 102, and simultaneously controls the vertical plate 307 to rotate on the support frame 304, causing the clamping assembly to drive the bearing... 102 rotates, flipping the bottom surface of the original bearing 102 upwards for inspection, thus completing the inspection of both the upper and lower end faces of the bearing 102. After the inspection is completed, the clamping assembly resets and places the clamped bearing 102 back onto the inspection conveyor belt 201. The bearing 102 then continues to be conveyed into the outer ring inspection area 4 for outer ring inspection, and then into the inner ring inspection area 5 for inner ring inspection, thus completing the entire inspection operation of the bearing 102. Then, based on the pass / fail status of the inspection, the qualified and unqualified bearings 102 are separated and unloaded through the unloading plate 205, completing the collection.

[0024] It should be noted that both the feeding conveyor belt 101 and the inspection conveyor belt 201 are driven intermittently. Each time, the feeding conveyor belt 101 and the inspection conveyor belt 201 move only a fixed distance. During the interval of movement, the inspection of a single bearing 102 is completed. Then, the conveyor belt drives the next bearing 102 to the inspection position, thereby starting the inspection operation of the next bearing 102.

[0025] Example 2: Refer to Figures 1-4 , Figure 6 , Figure 7 and Figure 10An automated bearing inspection line includes a feeding bracket 1 and an inspection bracket 2, a feeding conveyor belt 101 mounted on the feeding bracket 1 and an inspection conveyor belt 201 mounted on the inspection bracket 2; an end face inspection area 3, an outer ring inspection area 4 and an inner ring inspection area 5 are sequentially mounted on the inspection bracket 2, with the end face inspection area 3 located at one end closer to the feeding bracket 1; a support frame 304 is slidably mounted within the end face inspection area 3, and a vertical plate 307 is rotatably mounted on the outer wall of the support frame 304, with a clamping assembly for clamping the bearing 102 on the vertical plate 307; a discharge plate 205 is located at one end of the inspection bracket 2 away from the feeding bracket 1; furthermore, a first support rod 301 is fixedly mounted on the inspection bracket 2, the first support rod 301 is located within the end face inspection area 3, a first fixing plate 302 is fixedly mounted on the top of the first support rod 301, a first cylinder 303 is mounted on the first fixing plate 302, and the support frame 304 is located at the output end of the first cylinder 303.

[0026] The clamping assembly includes a fixed block 308 and two clamping blocks 311. The fixed block 308 is fixedly mounted on the vertical plate 307. Each of the two clamping blocks 311 is fixedly mounted with a connecting block 310. Each end of the fixed block 308 is provided with a first pin 309. The two connecting blocks 310 are rotatably connected to the two first pins 309 respectively.

[0027] A first linear motor 315 is fixedly installed on the vertical plate 307. The output end of the first linear motor 315 is provided with an output rod 313. A second pin 314 is provided on the output rod 313. Pulling blocks 312 are fixedly connected to both connecting blocks 310. Pulling blocks 312 are provided with long slots. The second pin 314 is inserted into the long slots on the pulling blocks 312.

[0028] The clamping block 311 is provided with an arc groove, the support frame 304 is provided with a stepper motor 305, the output end of the stepper motor 305 is provided with a drive shaft 306, the vertical plate 307 is fixedly connected to the drive shaft 306, the end face detection area 3 is fixedly provided with a support plate 316, the bottom of the support plate 316 is provided with an end face camera 317, and the end face camera 317 is positioned above the clamping block 311.

[0029] In this embodiment, during end-face inspection, the bearing 102 is placed in the arc grooves on the two clamping blocks 311. First, the top surface of the bearing 102 is photographed by the end-face camera 317 located on the support plate 316. After the photographing is completed, the first linear motor 315 operates, driving the output rod 313 at the output end to move, thereby driving the pulling block 312 connected to the second pin 314 to move. Under the action of the first pin 309, the connecting block 310 can drive the clamping block 311 to rotate, so that the clamping block 311 clamps the bearing 102. It should be noted that the long groove on the pulling block 312 is set to be relatively long, and the output rod 313 drives the second pin 314 to move. 14 During movement, the long slot provides space for the pulling block 312 to move, preventing jamming. After clamping, the first cylinder 303 is activated, which moves the support frame 304 at the output end, causing the clamping assembly to move the bearing 102 upward. At this time, the end face camera 317 can take a picture of the top surface of the bearing 102. Then, the stepper motor 305 is activated, causing the drive shaft 306 to rotate, which in turn rotates the vertical plate 307 half a turn, causing the clamping assembly to rotate the bearing 102. At this time, the clamping assembly will make the bottom of the bearing 102 face upward, and the end face camera 317 can take a picture of the bottom surface of the bearing 102.

[0030] Example 3: Refer to Figures 1-4 , Figure 8 and Figure 9 An automated bearing inspection line includes a loading bracket 1 and an inspection bracket 2, a loading conveyor belt 101 mounted on the loading bracket 1, and an inspection conveyor belt 201 mounted on the inspection bracket 2; an end face inspection area 3, an outer ring inspection area 4, and an inner ring inspection area 5 are sequentially mounted on the inspection bracket 2, with the end face inspection area 3 located at one end closer to the loading bracket 1; a support frame 304 is slidably mounted within the end face inspection area 3, and a vertical plate 307 is rotatably mounted on the outer wall of the support frame 304, with a clamping assembly for clamping the bearing 102 on the vertical plate 307; and a unloading plate 205 is located on the inspection bracket 2 away from the loading bracket. One end of the frame 1; furthermore, a second fixing plate 401 is fixedly connected in the outer ring detection area 4, and an annular cylinder 402 and a cylindrical cylinder 403 are fixedly installed at the bottom of the second fixing plate 401. A cylindrical rod 404 is slidably connected in the cylindrical cylinder 403. A pressing block 405 is provided at the end of the cylindrical rod 404 away from the cylindrical cylinder 403. A first pressure sensor 406 is provided in the pressing block 405. A plurality of outer ring cameras 408 electrically connected to the first pressure sensor 406 are provided on the inner wall of the annular cylinder 402. A first spring 407 is also provided between the pressing block 405 and the cylindrical cylinder 403. The first spring 407 is sleeved on the outer wall of the cylindrical rod 404.

[0031] A third fixing plate 501 is fixedly installed in the inner ring detection area 5. A vertical rod 502 is fixedly installed at the bottom of the third fixing plate 501. A sliding rod 504 is slidably connected inside the vertical rod 502. A pressing plate 505 is fixedly installed at the bottom of the sliding rod 504. A second pressure sensor 506 is provided on the pressing plate 505. An annular block 503 is fixedly installed on the outer wall of the vertical rod 502. Multiple inner ring cameras 508 electrically connected to the second pressure sensor 506 are provided on the outer wall of the annular block 503. A second spring 507 is provided between the pressing plate 505 and the annular block 503. The second spring 507 is sleeved on the sliding rod 504.

[0032] The detection bracket 2 is fixedly equipped with second support rods 6 at positions below the outer ring detection area 4 and the inner ring detection area 5. Each of the two second support rods 6 is equipped with a fourth fixing plate 601. Each of the two fourth fixing plates 601 is equipped with a second cylinder 602 at its bottom. Each of the two second cylinders 602 is equipped with a horizontal plate 603 at its output end. Each of the two horizontal plates 603 is equipped with a second linear motor 606 at its bottom. The output end of the second linear motor 606 located below the outer ring detection area 4 is equipped with a convex block 604 corresponding to the pressing block 405. The output end of the second linear motor 606 located below the inner ring detection area 5 is equipped with a concave block 605 corresponding to the pressing plate 505.

[0033] The testing bracket 2 is provided with an auxiliary plate 202, which cooperates with the testing conveyor belt 201. The auxiliary plate 202 is provided with multiple grooves 203. The convex block 604 and concave block 605 can pass through the grooves 203 and move upward. The testing conveyor belt 201 is broken in the middle, and the distance of the break is less than the inner diameter of the bearing 102. Two partitions 204 are fixedly installed on the testing bracket 2. The two partitions 204 are respectively set on both sides of the broken testing conveyor belt 201, and the unloading plate 205 is set in the middle of the two partitions 204.

[0034] In this embodiment, after the bearing 102 moves to the bottom of the outer ring detection area 4, the second cylinder 602 located at the bottom of the outer ring detection area 4 will work, thereby pushing the horizontal plate 603 at its output end to move. This causes the horizontal plate 603 to drive the second linear motor 606 and the convex block 604 to move upward, thereby causing the convex block 604 to drive the bearing 102 to move upward. The bearing 102 will then fit perfectly onto the convex block 604. Then, the second linear motor 606 is started, driving the convex block 604 to drive the bearing 102 to move upward. The convex block 604 will then contact the pressing block 405, thereby pushing the pressing block 405 and the round rod 404 to slide upward inside the cylinder 403, while compressing the first spring 407. At this time, the first pressure sensor 406 will detect the pressure and send a signal, causing the outer ring camera 408 located on the annular cylinder 402 to take a picture for detection, thereby realizing the detection of the outer ring of the bearing 102.

[0035] When the bearing 102 moves to the position located in the inner ring detection area 5, the second cylinder 602 and the second linear motor 606 located at the bottom of the inner ring detection area 5 will perform the same operation as described above, causing the concave block 605 to move upward. At this time, the bearing 102 will be placed inside the concave block 605. While the concave block 605 moves upward, it will press the pressing plate 505, thereby causing the slide rod 504 to move inside the upright rod 502, and compressing the second spring 507. At this time, the second pressure sensor 506 will generate pressure, thereby sending a signal to cause the inner ring camera 508 to take a picture and complete the detection of the inner ring of the bearing 102.

[0036] The detection conveyor belt 201 is broken in the middle. When the bearing 102 moves, both ends are placed on the detection conveyor belt 201 on both sides, so it will not fall off. At the same time, it can facilitate the extension of the convex block 604 and concave block 605. The second linear motor 606 can not only drive the convex block 604 and concave block 605 to rise, but can also drive them to rotate, so that the bearing 102 rotates during detection, improving the detection effect. The partition 204 can provide space for the movement of the bearing 102, making it easy to move.

[0037] Reference Figures 1-5 Both the feeding bracket 1 and the detection bracket 2 are fixedly equipped with a drive frame 103. The drive frame 103 is equipped with a drive motor 104. The output end of the drive motor 104 is equipped with a drive pulley 105. Both the feeding conveyor belt 101 and the detection conveyor belt 201 are equipped with a conveyor pulley 106. The drive pulley 105 and the conveyor pulley 106 are connected to a conveyor belt 107.

[0038] In this invention, by starting the drive motor 104, the drive pulley 105 at the output end is driven to rotate. Then, under the action of the conveyor belt 107, the conveyor pulley 106 rotates, thereby causing the feeding conveyor belt 101 and the detection conveyor belt 201 connected to the conveyor pulley 106 to rotate, thus starting the conveying operation of the bearing 102. It should be noted that the drive motor 104 is driven intermittently, which can drive the feeding conveyor belt 101 and the detection conveyor belt 201 to move intermittently, which facilitates the detection operation.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
