Description

Technical Field

[0001] This invention relates to the field of testing technology, and more specifically, to a bearing outer ring testing device and method. Background Technology

[0002] In the bearing manufacturing process, the treatment of the bearing outer ring involves two key steps: cleaning and inspection. First, the bearing outer ring must be cleaned to remove impurities such as oil and iron filings from its surface, ensuring that subsequent inspection processes are not interfered with. After cleaning, the outer surface of the bearing outer ring must be inspected using testing equipment to identify any defects such as cracks, thereby ensuring that the quality of the bearing outer ring meets the usage standards.

[0003] After the bearing outer ring is cleaned, it is moved to the corresponding position on the testing equipment using a fixture, ensuring the continuity of the production process. To save costs, the fixture can only move in two vertical horizontal directions. During the repositioning of the bearing outer ring, continuous friction occurs between the bearing outer ring and the worktable surface, which may lead to wear on the bearing outer ring.

[0021] Clean the outer ring of the bearing;

[0022] Based on the completion of the outer ring cleaning of the bearing, the outer ring of the bearing is controlled to move along the first direction to the first detection table;

[0023] Based on the fact that the outer ring of the bearing is located on the first detection platform, the upper end face of the outer ring of the bearing is subjected to a first crack detection.

[0024] Based on the completion of the first crack detection, the bearing outer ring is controlled to move along the first direction to the first transfer platform, and the first detection result of the first crack detection is obtained; wherein, when the bearing outer ring is located on the first transfer platform, a portion of the lower end face of the bearing outer ring near the first receiving assembly is located above the first clearance groove, and a portion of the lower end face of the bearing outer ring away from the first receiving unit is located above the third clearance groove.

[0025] Based on the fact that the bearing outer ring is located on the first transfer table and the first detection result is qualified, the bearing outer ring is controlled to move along the first direction to the next processing station;

[0026] Based on the fact that the outer ring of the bearing is located on the first transfer platform and the first detection result is unqualified, the first transfer platform is controlled to rotate until the outer ring of the bearing falls to the first receiving unit.

[0027] In some embodiments, when the bearing outer ring is located on the first transfer platform, the outer circumferential contour of the bearing outer ring near the first receiving unit is misaligned with the first clearance groove.

[0028] In some embodiments, controlling the outer ring of the bearing to move along the first direction to the next processing station based on the bearing outer ring being located on the first transfer table and the first detection result being qualified includes:

[0029] Based on the fact that the bearing outer ring is located on the first transfer platform and the first detection result is qualified, control the bearing outer ring to move to the support platform along the first direction;

[0030] Since the outer ring of the bearing is located on the support platform, the outer ring of the bearing is rotated 180°;

[0031] Based on the completion of the bearing outer ring flipping, control the bearing outer ring to move along the first direction to the second detection table;

[0032] Based on the fact that the outer ring of the bearing is located on the second detection platform, a second crack detection is performed on the upper end face of the outer ring of the bearing.

[0033] Based on the completion of the second crack detection, the bearing outer ring is controlled to move along the first direction to the second transfer platform, and the second detection result of the second crack detection is obtained; wherein, when the bearing outer ring is located on the second transfer platform, a portion of the lower end face of the bearing outer ring near the second receiving assembly is located above the first clearance groove, and a portion of the lower end face of the bearing outer ring away from the second receiving unit is located above the third clearance groove; when the bearing outer ring is located on the second transfer platform, a portion of the outer circumferential contour of the bearing outer ring near the second receiving unit is misaligned with the first clearance groove;

[0034] Based on the fact that the bearing outer ring is located on the second transfer table and the second detection result is qualified, the bearing outer ring is controlled to move along the first direction to the next processing station;

[0037] With the bearing outer ring positioned on the first transfer platform, the second end face of the bearing outer ring is facing downwards.

[0040] To address the problem of reducing friction between the bearing outer ring and the worktable during bearing outer ring inspection, this invention offers the following advantages:

[0041] By creating a first, second, and third clearance groove on the cleaning station, the first inspection station, and the first transfer station, and ensuring that all three grooves extend along a first direction, the contact area between the bearing outer ring and these components is reduced. Simultaneously, the sum of the widths of the first and third clearance grooves is greater than the width of the second clearance groove. This results in a larger area at both ends of the bearing outer ring along the second direction within the first and third clearance grooves when the lateral movement assembly moves the bearing outer ring horizontally. This further reduces the contact area between the bearing outer ring and these components, thereby minimizing friction during movement and preventing wear due to excessive friction.

[0051] In the bearing manufacturing process, the outer ring 80 of the bearing is first cleaned. Then, multiple outer rings 80 are clamped and moved together by a transverse moving assembly to inspect their outer surfaces. By simultaneously cleaning and inspecting multiple outer rings 80, a continuous production line process is formed, improving the inspection efficiency of the outer rings 80. Because the transverse moving assembly needs to clamp and move outer rings 80 at different stations simultaneously, it can only move in two vertical horizontal directions to save costs. However, during the transfer of the outer rings 80, continuous friction occurs between the outer rings 80 and the cleaning table 11, the first inspection table 21, and the first transfer table 31, which may cause wear on the outer rings 80.

[0052] Example 1:

[0053] In this embodiment, to solve the above problems, the present invention provides a bearing outer ring 80 detection device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the bearing outer ring 80 detection device includes a cleaning component 10, a first detection component 20, a first transfer component 30, a receiving component 40, and a transverse movement component.

[0054] The cleaning assembly 10 includes a cleaning platform 11 and a spraying unit 12. The cleaning platform 11 is horizontally positioned, and the spraying unit 12 is located above the cleaning platform 11. When the bearing outer ring 80 is to be inspected, the bearing outer ring 80 can be placed on the cleaning platform 11, and then cleaning fluid can be sprayed onto the cleaning platform 11 through the spraying unit 12 to clean the bearing outer ring 80, remove surface impurities, and provide a clean basis for subsequent inspection.

[0055] The first detection assembly 20 includes a first detection table 21 and a first detection unit 22. The first detection table 21 is connected to the cleaning table 11 and is horizontally positioned. The first detection unit 22 is located above the first detection table 21. With the bearing outer ring 80 positioned on the first detection table 21, the first detection unit 22 detects at least the cracks on the upper end face of the bearing outer ring 80. The inner diameter of the bearing outer ring 80 is conical, therefore, the first end face with the larger inner diameter of the bearing outer ring 80 is positioned upwards, i.e., facing the cleaning assembly 10, to facilitate a more thorough cleaning of the inner circumferential surface of the bearing outer ring 80 by the cleaning assembly 10.

[0056] The first transfer assembly 30 includes a first transfer platform 31 and a first drive unit 32. The first transfer platform 31 is connected to the first inspection platform 21, which is horizontally positioned. After the lateral movement assembly moves the bearing outer ring 80 on the first inspection platform 21 to the first transfer platform 31, the first inspection unit 22 determines whether the bearing outer ring 80 is qualified. If qualified, the lateral movement assembly controls the bearing outer ring 80 to move along the first direction Q1 for subsequent inspection. If unqualified, the first drive unit 32 drives the first transfer platform 31 to rotate around the first axis, causing the first transfer platform 31 to tilt, and the bearing outer ring 80 moves along the second direction Q2 toward the receiving assembly 40. The first direction Q1 is perpendicular to the second direction Q2. Figure 3 The direction shown is from right to left, and the second direction Q2 is as follows: Figure 3 The direction shown is from bottom to top.

[0057] The receiving assembly 40 includes a first receiving unit 41. The first receiving unit 41 is located on the second direction Q2 of the first transfer table 31. The height of the first receiving unit 41 is lower than the height of the first transfer table 31. Thus, the first drive unit 32 drives the first transfer table 31 to rotate around the first axis. Through the height difference between the first receiving unit 41 and the first transfer table 31, the defective bearing outer ring 80 can be moved into the first receiving unit 41, thereby facilitating subsequent processing.

[0058] The cleaning station 11, the first inspection station 21, and the first transfer station 31 are arranged sequentially along the first direction Q1, with the first axis parallel to the first direction Q1. Each outer ring bearing needs to be inspected sequentially by passing through the cleaning station 11, the first inspection station 21, and the first transfer station 31. The traverse assembly can simultaneously drive multiple outer ring bearings to move. For example, after one outer ring bearing is cleaned, it moves to the first inspection station 21, while another outer ring bearing moves to the cleaning station 11 for cleaning. By traversely moving the outer ring bearings at multiple workstations synchronously, and by simultaneously operating the spraying unit 12 and the first inspection unit 22, efficient inspection of multiple bearing outer rings 80 is achieved.

[0059] like Figure 4As shown, a first clearance unit 33 is provided on the cleaning station 11, the first inspection station 21, and the first transfer station 31. The first clearance unit 33 includes a first clearance groove 331, a second clearance groove 332, and a third clearance groove 333. The first clearance groove 331, the second clearance groove 332, and the third clearance groove 333 all extend along the first direction Q1. In this way, during the movement of the outer ring bearing, the first clearance groove 331, the second clearance groove 332, and the third clearance groove 333 can reduce the contact area between the lower end face of the outer ring 80 of the bearing and the cleaning station 11, the first inspection station 21, and the first transfer station 31, respectively. Meanwhile, the second clearance groove 332 is located between the first clearance groove 331 and the third clearance groove 333. The sum of the widths of the first clearance groove 331 and the third clearance groove 333 is greater than the width of the second clearance groove 332. Because the second clearance groove 332 significantly reduces the area of ​​the bearing outer ring 80 at both ends along the first direction Q1, the sum of the widths of the first clearance groove 331 and the third clearance groove 333 is greater than the width of the second clearance groove 332. Furthermore, due to the annular nature of the outer ring bearing, the contact area between the first clearance groove 331 and the third clearance groove 333 and the two ends of the bearing outer ring 80 along the second direction Q2 is larger. This reduces the contact area between the bearing outer ring 80 and the cleaning table 11, the first inspection table 21, and the first transfer table 31, thereby reducing the frictional force of the transverse component moving the bearing outer ring 80 along the first direction Q1.

[0060] In some embodiments, the first detection unit 22 is also used to detect cracks on the circumferential surface of the bearing outer ring 80. That is, the first detection unit 22 is used to detect cracks on the inner and / or outer circumferential surfaces of the bearing outer ring 80.

[0061] Furthermore, when the bearing outer ring 80 with a conical inner circumferential surface is located on the first detection table 21, the first end face with a larger inner diameter of the bearing outer ring 80 faces upward. Preferably, since the normal direction of the inner circumferential surface of the bearing outer ring 80 faces upward, cracks on the inner circumferential surface are easier to detect. Therefore, the first detection unit 22 is used to detect cracks on the inner circumferential surface of the bearing outer ring 80.

[0062] In other embodiments, such as Figure 1 As shown, the bearing outer ring 80 detection device also includes a flipping component 50, a second detection component 60, and a second transfer component 70.

[0063] The flipping assembly 50 includes a support platform 51 and a flipping robot 52. The support platform 51 is horizontally positioned, and the flipping robot 52 is located above the support platform 51. The support platform 51 is connected to the first transfer table 31. The support platform 51 provides a placement position for the bearing outer ring 80, and the flipping robot 52 can control the bearing outer ring 80 on the support platform 51 to rotate 180°, thereby realizing the conversion of the upper and lower end faces of the bearing outer ring 80, so as to inspect both end faces of the bearing outer ring 80 and improve the comprehensiveness of the inspection.

[0064] The second inspection assembly 60 includes a second inspection table 61 and a second inspection unit 62. The second inspection table 61 is connected to the support platform 51 and is horizontally positioned. The second inspection unit 62 is located above the second inspection table 61. The second inspection table 61 can support the overturned bearing outer ring 80. Since the first inspection unit 22 has inspected the upper end face of the bearing outer ring 80 and determined it to be qualified, the second inspection unit 62 needs to inspect at least the cracks on the upper end face of the bearing outer ring 80 on the second inspection table 61. That is, the second end face with the smaller inner diameter of the bearing outer ring 80 needs to be inspected, thereby ensuring that neither end face of the bearing outer ring 80 is missed through the inspections of the first inspection unit 22 and the second inspection unit 62.

[0065] The second transfer assembly 70 includes a second transfer platform 71 and a second drive unit 72. The second transfer platform 71 is connected to the second inspection platform 61 and is horizontally positioned. The second drive unit 72 is connected to the second transfer platform 71. The second drive unit 72 controls the second transfer platform 71 to rotate around a first axis. After the lateral movement assembly moves the bearing outer ring 80 on the second inspection platform 61 to the second transfer platform 71, the bearing outer ring 80 is judged to be qualified based on the inspection result of the second inspection unit 62. If qualified, the bearing outer ring 80 is controlled to move along the first direction Q1 by the lateral movement assembly for subsequent testing. If unqualified, the second drive unit 72 drives the second transfer platform 71 to rotate around the first axis, causing the second transfer platform 71 to tilt, and the bearing outer ring 80 slides towards the receiving assembly 40 along the second direction Q2.

[0066] The receiving assembly 40 also includes a second receiving unit 42, which is located on the second transfer platform 71 in the second direction Q2. The height of the second receiving unit 42 is lower than the height of the second transfer platform 71. The first transfer platform 31, the support platform 51, the second inspection platform 61, and the second transfer platform 71 are arranged sequentially along the first direction Q1. Each of the first transfer platform 31, the support platform 51, the second inspection platform 61, and the second transfer platform 71 is equipped with a first clearance unit 33. Each outer ring bearing needs to be inspected sequentially through the cleaning platform 11, the first inspection platform 21, the first transfer platform 31, the support platform 51, the second inspection platform 61, and the second transfer platform 71. When the second inspection platform 61 detects that the bearing outer ring 80 is unqualified, the second transfer platform 71 and the second drive unit 72 move the bearing outer ring 80 to the second receiving unit 42, thereby classifying qualified and unqualified bearing outer rings 80 to ensure that qualified bearing outer rings 80 are put into use.

[0067] In other embodiments, when the bearing outer ring 80 with a conical inner circumferential surface is located on the first inspection stage 21, the first end face with the larger inner diameter of the bearing outer ring 80 faces upwards, and the first end face is inspected, while the inner circumferential surface of the bearing outer ring 80 is also inspected. When the bearing outer ring 80 with a conical inner circumferential surface is located on the second inspection stage 61, the second end face with the smaller inner diameter of the bearing outer ring 80 faces upwards, and the second end face is inspected, while the outer circumferential surface of the bearing outer ring 80 is also inspected. This ensures that the surface of the bearing outer ring 80 is comprehensively inspected.

[0068] Furthermore, such as Figure 3 As shown, a second clearance unit 34 is provided on the upper surface of the first transfer station 31 near the first receiving unit 41. The second clearance unit 34 includes a fourth clearance groove 341. The fourth clearance groove 341 extends along the second direction Q2 and is located on the side of the first clearance groove 331 away from the second clearance groove 332. When the first detection unit 22 detects that the upper end face of the bearing outer ring 80 is unqualified, and the bearing outer ring 80 moves onto the first transfer station 31, the first drive unit 32 drives the first transfer station 31 to tilt towards the first receiving unit 41. The fourth clearance groove 341 extends along the second direction Q2, reducing the contact area between the bearing outer ring 80 and the first transfer station 31, thereby reducing the friction between the bearing outer ring 80 and the first transfer station 31, allowing the bearing outer ring 80 to slide better onto the first receiving assembly 40. Meanwhile, because the sliding direction of the bearing outer ring 80 lacks constraint guidance, and due to the setting of the fourth relief groove 341, when the bearing outer ring 80 tends to slide along the first direction Q1, the elongated pit shape of the fourth relief groove 341 will generate resistance with the solid part of the fourth relief groove 341 and the first transfer platform 31, thereby increasing the resistance of the bearing outer ring 80 along the first direction Q1, and thus reducing the possibility of the sliding direction of the bearing outer ring 80 deviating during the process of sliding to the first receiving assembly 40.

[0069] A second clearance unit 34 is provided on the upper surface of the second transfer table 71 near the second receiving unit 42. When the second detection unit 62 detects that the lower end face of the bearing outer ring 80 is defective, and the bearing outer ring 80 moves onto the second transfer table 71, the second drive unit 72 drives the second transfer table 71 to tilt towards the second receiving unit 42. The fourth clearance groove 341 reduces the contact area between the bearing outer ring 80 and the second transfer table 71, thereby reducing the friction between the bearing outer ring 80 and the second transfer table 71, allowing the bearing outer ring 80 to slide more effectively onto the second receiving assembly 40. It also reduces the possibility of the bearing outer ring 80 deviating in the sliding direction during its movement onto the second receiving assembly 40.

[0070] Furthermore, such as Figure 3As shown, the widths of the first clearance groove 331, the second clearance groove 332, and the third clearance groove 333 are all greater than the width of the fourth clearance groove 341. This effectively reduces the contact area between the bearing outer ring 80 and the cleaning table 11, the first inspection table 21, the first transfer table 31, the support table 51, the second inspection table 61, and the second transfer table 71 as they move along the first direction Q1. The fourth clearance groove 341 reduces the contact area between the first transfer table 31 or the second transfer table 71 and the bearing outer ring 80, thus reducing the friction between the bearing outer ring 80 and the first transfer table 31 when the bearing outer ring 80 slides towards the receiving assembly 40. If the width of the fourth clearance groove 341 is too large, and the bearing outer ring 80 slides along the second direction Q2 without proper guidance, some of the bearing outer ring 80 may fall into the fourth clearance groove 341, causing the bearing outer ring 80 to become stuck. Therefore, by setting the width of the fourth clearance groove 341 to be smaller, the friction between the outer ring 80 of the bearing and the first transfer platform 31 or the second transfer platform 71 can be reduced, and some of the outer ring 80 of the bearing can be prevented from falling into the fourth clearance groove 341 and getting stuck.

[0071] Furthermore, such as Figure 3 As shown, each second clearance unit 34 has multiple fourth clearance grooves 341. The distance between the first clearance groove 331 and the second clearance groove 332 is greater than the distance between two adjacent fourth clearance grooves 341. The distance between the second clearance groove 332 and the third clearance groove 333 is greater than the distance between two adjacent fourth clearance grooves 341. In this way, the relatively dense and narrow fourth clearance grooves 341 restrict the direction of the bearing outer ring 80 sliding towards the receiving assembly 40, while also reducing the friction between the bearing outer ring 80 and the first transfer platform 31 and the second transfer platform 71 respectively. This allows the defective bearing outer ring 80 to slide accurately into the receiving assembly 40.

[0072] Example 2:

[0073] In this embodiment, the present application provides a bearing outer ring 80 detection method applied to the bearing outer ring 80 detection method in Embodiment 1. For example... Figure 6 As shown, the method for inspecting the outer ring 80 of the bearing includes steps S10 to S60. Steps S10 to S60 will be described in detail below:

[0074] Step S10 involves cleaning the outer ring 80 of the bearing to remove iron filings and oil stains from its surface, thus preventing these substances from interfering with subsequent testing procedures and ensuring the accuracy of the test results, thereby improving the reliability of the testing.

[0075] In step S20, based on the completion of cleaning of the bearing outer ring 80, the lateral movement component controls the bearing outer ring 80 to move along the first direction Q1 to the first inspection stage 21. This achieves an orderly connection between the cleaning process and the inspection process, ensuring the continuity of the inspection.

[0076] Step S30: Based on the bearing outer ring 80 being located on the first inspection table 21, a first crack detection is performed on the upper end face of the bearing outer ring 80, i.e., the first end face with the larger inner diameter of the bearing outer ring 80 faces upwards. This promptly detects whether there are cracks on the first end face of the bearing outer ring 80, and simultaneously checks whether there are cracks on the inner circumferential surface of the bearing outer ring 80, thereby identifying unqualified bearing outer rings 80 in advance and preventing unqualified bearing outer rings 80 from entering subsequent processes, ensuring the quality of the bearing outer ring 80.

[0077] In step S40, based on the completion of the first crack detection, the bearing outer ring 80 is controlled to move along the first direction Q1 to the first transfer station 31, and the first detection result of the first crack detection is obtained, which facilitates subsequent classification processing based on the detection result. Specifically, when the bearing outer ring 80 is located on the first transfer station 31, the cleaning station 11, or the first detection station 21, a portion of the lower end face of the bearing outer ring 80 near the first receiving assembly 40 is located above the first clearance groove 331, and a portion of the lower end face of the bearing outer ring 80 away from the first receiving assembly 41 is located above the third clearance groove 333. Thus, the area of ​​the bearing outer ring 80 located above the first clearance groove 331 or the third clearance groove 333 is larger than the area of ​​the bearing outer ring 80 located above the second clearance groove 332 located in the middle, thereby further reducing the contact area between the bearing outer ring 80 and the first transfer station 31, the cleaning station 11, and the first detection station 21, and thus reducing the friction between the bearing outer ring 80 and the first transfer station 31.

[0078] In step S50, based on the bearing outer ring 80 being located on the first transfer station 31 and the first inspection result being qualified, the bearing outer ring 80 is controlled to move along the first direction Q1 to the next processing station. This ensures the continuity of the processing steps, improves overall processing efficiency, and achieves the effect of qualified products smoothly entering the next stage.

[0079] After step S40 is completed, one of steps S50 and S60 is executed. In step S60, based on the bearing outer ring 80 being located on the first transfer table 31 and the first detection result being unqualified, the first transfer table 31 is controlled to rotate until the bearing outer ring 80 falls into the first receiving unit 41. This achieves automatic collection of unqualified products, avoids mixing of unqualified and qualified products, facilitates centralized processing of unqualified products, solves the problem of difficult sorting of unqualified products, and achieves the effect of automatic sorting of unqualified products.

[0080] Furthermore, with the outer ring 80 of the bearing positioned on the first transfer platform 31, the outer circumference of the outer ring 80 near the first receiving unit 41 is misaligned with the first clearance groove 331. This misalignment, with the inner circumference above the first clearance groove 331 and the outer circumference offset from it, allows the first transfer platform 31 to smoothly slide into the receiving assembly 40 when rotating around the first axis. This prevents the outer ring 80 from having all its arc near the first receiving unit 41 positioned above the first clearance groove 331, which could cause part of the outer ring 80 to fall into the first clearance groove 331 during sliding, thus preventing jamming.

[0081] Further, step S50 includes steps S51 to S57. The bearing outer ring 80 inspection method sequentially executes steps S10, S20, S30, S40, S51, S52, S53, S54, S55, S56, or S57. Steps S51 to S57 will be described in detail below:

[0082] In step S51, based on the bearing outer ring 80 being located on the first transfer platform 31 and the first detection result being qualified, the lateral movement component controls the bearing outer ring 80 to move along the first direction Q1 to the support platform 51. By moving the bearing outer ring 80 to the support platform 51, a stable support base can be provided for the subsequent flipping operation, preventing the bearing outer ring 80 from shaking or shifting during the flipping process.

[0083] In step S52, based on the bearing outer ring 80 being located on the support platform 51, the bearing outer ring 80 is rotated 180°. This makes the originally downward-facing end face of the bearing outer ring 80 face upward, thus facilitating the inspection of the rotated end face. This allows for comprehensive inspection of both end faces of the bearing outer ring 80, avoiding the omission of crack defects due to only inspecting one end face, and ultimately improving the completeness and accuracy of product inspection.

[0084] Step S53: After the bearing outer ring 80 has been flipped, control the bearing outer ring 80 to move along the first direction Q1 to the second inspection table 61. By moving the bearing outer ring 80 to the second inspection table 61 after the flipping is completed, the flipping process and the second crack inspection process can be connected in an orderly manner, ensuring the smooth progress of the inspection work, guaranteeing the stability of the inspection environment, and achieving a smooth transition between processes.

[0085] Step S54: Based on the bearing outer ring 80 being located on the second inspection table 61, a second crack detection is performed on the upper end face of the bearing outer ring 80. Simultaneously, the surface of the outer diameter of the bearing outer ring 80 is inspected. This achieves comprehensive inspection of both end faces and the outer surface of the bearing outer ring 80, avoiding missed detections and ultimately ensuring product quality, thus achieving the effect of comprehensive inspection.

[0086] In step S55, based on the completion of the second crack detection, the bearing outer ring 80 is controlled to move along the first direction Q1 to the second transfer platform 71, and the second detection result of the second crack detection is obtained. Specifically, when the bearing outer ring 80 is located on the second transfer platform 71 or the support platform 51, a portion of the lower end face of the bearing outer ring 80 near the second receiving assembly 40 is located above the first clearance groove 331, and a portion of the lower end face of the bearing outer ring 80 away from the second receiving unit 42 is located above the third clearance groove 333. Thus, the area of ​​the bearing outer ring 80 located above the first clearance groove 331 or the third clearance groove 333 is larger than the area of ​​the bearing outer ring 80 located above the second clearance groove 332, thereby further reducing the contact area between the bearing outer ring 80 and the second transfer platform 71 and the support platform 51, and consequently reducing the frictional force between the bearing outer ring 80 and the second transfer platform 71 and the support platform 51. With the bearing outer ring 80 positioned on the second transfer platform 71, the arc of the outer circumference of the bearing outer ring 80 near the second receiving unit 42 is misaligned with the first clearance groove 331. For example... Figure 5 As shown, the outer circumferential contour of the bearing outer ring 80 is located near the second receiving unit 42, and the solid part of the second transfer table 71 and the first clearance groove 331 is located near the second receiving assembly 40. This ensures that when the bearing outer ring 80 is defective, the bearing outer ring 80 can smoothly slide into the second receiving assembly 40 when the second transfer table 71 is tilted and rotated.

[0087] Step S56: Based on the bearing outer ring 80 being located on the second transfer station 71 and the second inspection result being qualified, control the bearing outer ring 80 to move along the first direction Q1 to the next processing station. This ensures the orderly flow of qualified bearing outer rings 80, guarantees the continuity of processing steps, thereby improving overall processing efficiency and achieving the effect of qualified products smoothly entering the next stage.

[0088] After step S55 is completed, one of steps S56 and S57 is executed. In step S57, based on the bearing outer ring 80 being located on the second transfer platform 71 and the second detection result being unqualified, the second transfer platform 71 is controlled to rotate until the bearing outer ring 80 falls to the second receiving unit 42. This automatically collects the unqualified bearing outer ring 80, preventing it from mixing with qualified bearing outer rings 80, thus facilitating centralized processing of the unqualified bearing outer rings 80.

[0089] Furthermore, the inner circumferential wall of the bearing outer ring 80 is tapered. The bearing outer ring 80 has a first end face and a second end face. The inner diameter of the first end face is larger than the inner diameter of the second end face. When the bearing outer ring 80 is positioned on the first turntable 31, the second end face of the bearing outer ring 80 faces downwards. The first end face is as follows... Figure 3 The image shows the upward-facing side of the bearing outer ring 80 located on the first transfer platform 31. The second end face is as shown. Figure 3The image shows the upward-facing side of the bearing outer ring 80 located on the second transfer platform 71. Since the bearing outer ring 80 needs to be cleaned before passing the support, having the first end face of the bearing outer ring 80 facing upward allows for more effective cleaning of surface impurities, thus facilitating the detection by the first detection unit 22 and ensuring the accuracy of the detection results.

[0090] Furthermore, such as Figure 4 As shown, because the inner circumferential wall of the bearing outer ring 80 is conical, when the bearing outer ring 80 is positioned on the first transfer platform 31, the end face with the larger inner diameter of the bearing outer ring 80 faces upwards. This causes the portion of the inner circumferential contour of the bearing outer ring 80 that is away from the first receiving unit 41 to form an obtuse angle with the first transfer platform 31 when the first transfer platform 31 first begins to tilt. This makes it easy for the bearing outer ring 80 to get stuck with the solid portion of the first transfer platform 31 located in the third clearance groove 333. Therefore, in this application, the portion of the inner circumferential contour of the bearing outer ring 80 that is away from the first receiving unit 41 is misaligned with the third clearance groove 333. That is, the portion of the inner circumferential contour of the bearing outer ring 80 that is away from the first receiving unit 41 is located on the first transfer platform 31. This avoids the possibility of the bearing outer ring 80 getting stuck with the first transfer platform 31 due to insufficient sliding force when the first transfer platform 31 first begins to tilt.

[0091] With the outer ring 80 of the bearing positioned on the second intermediate turntable 71, as follows: Figure 5 As shown, the arc of the inner circumferential contour of the bearing outer ring 80, away from the second receiving unit 42, is located above the third clearance groove 333. The arc of the inner circumferential contour of the bearing outer ring 80, away from the second receiving unit 42, forms an acute angle with the second transfer table 71. Even if the initial sliding force is insufficient, the bearing outer ring 80 is driven to slide to the first receiving assembly 40 due to the influence of the arc of the inner circumferential contour of the bearing outer ring 80 near the second receiving unit 42 and the second transfer table 71. Therefore, because the arc of the inner circumferential contour of the bearing outer ring 80, away from the second receiving unit 42, is located above the third clearance groove 333, the frictional force of the bearing outer ring 80 moving along the first direction Q1 is reduced.

[0092] In other embodiments, the cleaning station 11, the first inspection station 21, the first transfer station 31, the support station 51, the second inspection station 61, and the second transfer station 71 are each provided with a plurality of second clearance grooves 332, thereby further reducing the friction of the cleaning station 11, the first inspection station 21, the first transfer station 31, the support station 51, the second inspection station 61, and the second transfer station 71, so that the outer ring 80 of the bearing can move better along the first direction Q1 and reduce the wear of the outer ring 80 of the bearing.

[0093] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
