Description

Technical Field

[0001] This invention relates to the field of bearing testing equipment technology, and in particular to a rapid testing machine for bearing race inner gauges. Background Technology

[0002] The bearing ring inner gauge rapid inspection machine is an automated device specifically designed for the rapid inspection of the inner diameter of bearing rings. It is widely used in the quality inspection process of the bearing manufacturing industry. It uses a plug-and-go gauge method to determine whether the ring bore diameter is within the acceptable range. Compared to existing visual inspection methods, its structure is simpler and more intuitive, and its cost is lower, making it an indispensable inspection step in the bearing production process. Existing bearing ring inner gauge rapid inspection machines primarily rely on manual loading, inspection, and unloading, and cannot be seamlessly integrated with existing bearing inspection production lines. This prevents rapid batch inspection and significantly reduces the inspection speed of bearing rings. When the number of bearings is large, this often becomes a bottleneck in the inspection process, affecting the overall speed of bearing production and inspection. Summary of the Invention

[0003] The main objective of this invention is to provide a rapid inspection machine for bearing ring inner gauges, which aims to solve the problems of existing rapid inspection machines being unable to seamlessly integrate with bearing inspection production lines and being unable to perform rapid batch inspections. By setting up mechanisms for conveying, feeding, discharging, and inner diameter inspection, the invention achieves an automated inspection process and improves inspection efficiency.

[0004] To achieve the above objectives, the present invention proposes a bearing ring inner diameter rapid inspection machine, comprising a frame, characterized in that a conveying mechanism is provided on the frame, the conveying mechanism being connected to an external bearing inspection device; the frame is also provided with a feeding mechanism and a discharging mechanism arranged sequentially along the conveying direction of the conveying mechanism, and an inner diameter inspection mechanism is provided between the feeding mechanism and the discharging mechanism, the inner diameter inspection mechanism being used to inspect the inner diameter of the bearing ring when the conveying mechanism delivers the bearing ring to the inner diameter inspection station.

[0005] In one possible implementation, the inner diameter detection mechanism includes a mounting bracket mounted on a frame, on which a go / no-go gauge assembly and a drive assembly are mounted. It also includes a sensor assembly mounted on the frame for detecting the go / no-go gauge assembly. The go / no-go gauge assembly is slidably mounted on the mounting bracket. The drive assembly is used to drive the go / no-go gauge assembly to slide up and down above the conveying mechanism. The sensor assembly is used to detect the position of the go / no-go gauge assembly.

[0006] In one possible implementation, the go / no-go gauge assembly includes a connecting plate slidably connected to the mounting bracket. The connecting plate is connected to the drive assembly and a connecting rod is fixedly mounted thereon. A go gauge and a no-go gauge are mounted on the connecting rod. The outer diameter of the go gauge is smaller than that of the no-go gauge, and the no-go gauge is coaxially mounted on the upper end of the outer circumference of the go gauge.

[0007] In one possible implementation, the no-go gauge is slidably connected to the go gauge, and a locking component is provided at the upper end of the no-go gauge, the locking component being used to fix the position of the no-go gauge on the go gauge.

[0008] In one possible implementation, the locking assembly includes a mounting ring fixedly disposed on the upper end of the go gauge member, the upper end of the mounting ring being elastically provided with a plurality of circumferentially distributed locking teeth, the inner wall of the locking teeth being in contact with the outer side of the go gauge member; it also includes a control ring threadedly connected to the mounting ring, the inner side of the control ring and the outer side of the locking teeth being provided with mutually contacting pressing surfaces, the pressing surfaces being conical, when the control ring moves toward the locking teeth, a plurality of the locking teeth will deform toward the go gauge member to press the go gauge member.

[0009] In one possible implementation, the conveying mechanism includes a conveying track mounted on a frame and a material handling robot mounted on the conveying track; the conveying track is provided with a through hole located below the go / no-go gauge assembly, the inner diameter of the through hole being larger than the inner diameter of the bearing ring and smaller than the outer diameter of the bearing ring; The sensor assembly includes a first sensor and a second sensor. The first sensor is disposed on one side of the through hole and is triggered when the go gauge descends through the bearing ring into the through hole. The second sensor is disposed above the conveyor track and is triggered when the stop gauge passes by.

[0010] In one possible implementation, the frame is provided with a cleaning mechanism located below the through hole, the cleaning mechanism being used to clean the inner wall of the bearing race when the bearing race reaches below the go / no-go gauge assembly; it also includes a limiting plate provided above the through hole, the limiting plate being provided with a guide hole coaxial with the go / no-go gauge component.

[0011] In one possible implementation, the cleaning mechanism includes a support frame disposed below the frame, a sliding frame connected to a pneumatic lifting rod on the support frame, and a cleaning head rotatably disposed on the sliding frame; the cleaning head is connected to a drive motor, which drives the cleaning head to rotate to clean the inner wall of the bearing race when the cleaning head is inserted into the bearing race.

[0012] In one possible implementation, the cleaning head includes a rotating shaft connected to the output shaft of a drive motor, a movable plate slidably disposed on the rotating shaft, a spring disposed between the movable plate and a sliding frame, a plurality of cleaning plates slidably disposed around the movable plate, and a spring disposed between the cleaning plates and the movable plate; the plurality of cleaning plates are disposed perpendicular to the sliding frame to form a cylindrical structure, and a soft brush is disposed on the outer side of the cleaning plate.

[0013] In one possible implementation, the upper end of the cleaning plate extends towards the center of the rotating shaft with a guide plate, and a plurality of the guide plates are inclined upward to form an arc structure protruding above the through hole; the gauge member is hollow and has a clearance opening on its lower end face, and the edge of the clearance opening is chamfered; the cylindrical structure formed by the plurality of cleaning plates can be inserted into the gauge member through the clearance opening.

[0014] In summary, the beneficial effects of this application are as follows: Compared with the prior art, the bearing ring inner gauge rapid inspection machine of the present invention can smoothly receive and transport bearing rings by setting up a conveying mechanism connected to an external bearing inspection device. With the feeding, discharging and inner diameter inspection mechanisms arranged in sequence along the conveying direction, it can achieve seamless docking with the bearing inspection production line, realize an automated batch rapid inspection process, greatly improve inspection efficiency, and avoid forming a bottleneck in the bearing production inspection process.

[0015] The inner diameter inspection mechanism employs the go / no-go gauge method. A drive assembly moves the go / no-go gauge assembly up and down, allowing the go and no-go gauges to inspect the inner diameter of the bearing rings in an orderly manner. The outer diameter of the go gauge is smaller than that of the no-go gauge. When the go gauge passes through the bearing ring and triggers the first sensor, it indicates that the inner diameter is larger than the outer diameter of the go gauge. If the no-go gauge cannot pass through, preventing the second sensor from triggering, it indicates that the inner diameter is smaller than the outer diameter of the no-go gauge. This accurately determines whether the inner diameter is within the acceptable range, ensuring inspection accuracy. The locking component within the go / no-go gauge assembly, through the conical extrusion surface structure of the control ring and locking teeth, can flexibly and stably adjust the position of the no-go gauge on the go gauge to accommodate the inspection requirements of bearing rings of different thicknesses.

[0016] The conveying mechanism's conveyor track features through holes of a specific inner diameter, located below the go / no-go gauge assembly. This provides space for the go / no-go gauge to pass through the bearing race, and works in conjunction with a sensor assembly at a corresponding position to accurately report the detection status. Before detection, the cleaning mechanism uses a pneumatic lifting rod to raise the cleaning head, equipped with a drive motor, into the bearing race. The drive motor rotates the cleaning head, and the moving plate and cleaning plate in the cleaning head's special structure can adaptively adjust their positions under the action of springs. The outer soft brush effectively cleans the inner wall, not only removing impurities that may affect the detection and ensuring accuracy, but also reducing wear on the go / no-go gauge assembly, thus providing protection. The limiting plate has guide holes coaxial with the go / no-go gauge, providing precise guidance for the insertion of the go / no-go gauge assembly into the bearing race, further improving the accuracy and stability of the detection.

[0020] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Example 1

[0022] like Figure 1-7 As shown, the present invention proposes a bearing ring inner gauge rapid inspection machine, including a frame 1, a conveying mechanism 2 on the frame 1, and an external bearing inspection device connected to the conveying mechanism 2.

[0023] The conveying mechanism 2 is used to convey bearing rings, and includes a conveying track 20 mounted on the frame 1 and a transfer robot 21 mounted on the conveying track 20; the transfer robot 21 can forward convey the bearing rings located on the conveying track 20; for example Figure 2 As shown, the material handling robot 21 has a prior art structure. It can slide back and forth and left and right on a horizontal plane. It includes a fixed base on the frame 1, a front and rear translation guide rail on the fixed base, a front and rear movable worktable on the front and rear translation guide rail, a transverse cylinder on the front and rear movable worktable, and the movable end of the transverse cylinder is connected to the strip claw plate.

[0024] During operation, the front and rear movable worktables slide along the front and rear translational guide rails to the front of the bearing rings. The transverse cylinder drives the strip claw plate to move to both sides of the bearing rings and grab them. Then, the front and rear movable worktables slide backward along the guide rails, conveying the bearing rings forward to the designated position. After that, the transverse cylinder resets, causing the strip claw plate to move away from the bearing rings. This cycle is repeated to continuously convey the bearing rings on the conveying track 20.

[0025] It also includes a main control device set on the frame 1. The material handling robot 21 is connected to the main control device and is used to control the forward conveying of the bearing rings.

[0026] The frame 1 is also equipped with a feeding mechanism 3 and a discharging mechanism 4 arranged sequentially along the conveying direction of the conveying mechanism 2. Both the feeding mechanism 3 and the discharging mechanism 4 are conveyor belt assemblies, which can deliver the bearing rings out or into the conveying track 20.

[0027] At the same time, such as Figure 2-3 As shown, an inner diameter detection mechanism 5 is provided between the feeding mechanism 3 and the discharging mechanism 4. The inner diameter detection mechanism 5 is used to detect the inner diameter of the bearing ring when the conveying mechanism 2 sends the bearing ring to the inner diameter detection station.

[0028] The inner diameter detection mechanism 5 includes a mounting bracket 50 mounted on the frame 1. The mounting bracket 50 is equipped with a go / no-go gauge assembly 51 and a drive assembly 52. ​​It also includes a sensor assembly 53 mounted on the frame 1 for detecting the go / no-go gauge assembly 51. The go / no-go gauge assembly 51 is slidably mounted on the mounting bracket 50. The drive assembly 52 is used to drive the go / no-go gauge assembly 51 to slide up and down above the conveying mechanism 2. The sensor assembly 53 is used to detect the position of the go / no-go gauge assembly 51.

[0029] Specifically, the drive assembly 52 is a pneumatic telescopic rod mounted on the mounting frame 50, and the output end of the pneumatic telescopic rod is connected to the go / no-go gauge assembly 51. The go / no-go gauge assembly 51 includes a connecting plate 511 that is slidably connected to the mounting frame 50. A connecting rod 512 is fixedly mounted on the connecting plate 511 and the output end of the pneumatic telescopic rod. A go gauge 513 and a no-go gauge 514 are mounted on the connecting rod 512. The outer diameter of the go gauge 513 is smaller than that of the no-go gauge 514, and the no-go gauge 514 is coaxially mounted on the upper end of the outer circumference of the go gauge 513.

[0030] The sensor assembly 53 includes a first sensor 530 and a second sensor 531. The first sensor 530 and the second sensor 531 can be proximity switch sensors. The first sensor 530 is disposed on one side of the through hole 22 and is triggered when the go gauge 513 passes through the bearing ring and descends into the through hole 22. The second sensor 531 is disposed above the conveying track 20 and is triggered when the stop gauge 514 passes by.

[0031] When the bearing ring arrives at the inner diameter inspection station with the conveying mechanism 2, the pneumatic telescopic rod on the mounting frame 50 is activated. Its output end pushes the connecting plate 511 of the go / no-go gauge assembly 51 connected to it. Since the connecting plate 511 is slidably connected to the mounting frame 50, under the action of the pneumatic telescopic rod, the connecting rod 512 fixed on the connecting plate 511, as well as the go gauge 513 and no-go gauge 514 on the connecting rod 512, slide down the mounting frame 50 above the conveying mechanism 2.

[0032] The outer diameter of the go gauge 513 is relatively small, so it first contacts the bearing race. If the inner diameter of the bearing race meets the requirements and is larger than the outer diameter of the go gauge 513, the go gauge 513 will pass through the bearing race and continue to descend until it falls into the through hole 22 located below the go / no-go gauge assembly 51 on the conveying track 20. At this time, the first sensor 530 located on one side of the through hole 22 is triggered, indicating that the go gauge 513 has passed through successfully.

[0033] At the same time, the no-go gauge 514 and the GO gauge 513 descend synchronously, and the distance between the lower end of the no-go gauge 514 and the lower end of the GO gauge 513 is adapted to the thickness of the bearing ring. That is, the distance between the no-go gauge 514 and the GO gauge 513 is slightly greater than the thickness of the bearing ring, so that the lower end of the GO gauge 513 can completely pass through the bearing ring.

[0034] If the inner diameter of the bearing ring is within acceptable limits and smaller than the outer diameter of the go-no-go gauge 514, the go-no-go gauge 514 cannot pass through the bearing ring. When the go-no-go gauge 514 passes the second sensor 531 located above the conveyor track 20, if the second sensor 531 is not triggered, it means that the go-no-go gauge 514 has failed to pass, thus determining that the inner diameter of the bearing ring is within the acceptable range; if the second sensor 531 is triggered, it means that the go-no-go gauge 514 has passed through the bearing ring, i.e., the inner diameter of the bearing ring is too large and does not meet the standard. After completing this inspection action, the pneumatic telescopic rod drives the go-no-go gauge assembly 51 to slide upward and reset, waiting for the next bearing ring to enter the inspection station.

[0035] Meanwhile, in order to ensure that the cylinder continues to move after the no-go gauge 514 comes into contact with the bearing ring, a pressure sensor is provided between the go gauge 513 and the connecting plate 511. The pressure sensor is connected to the main control equipment and is used to drive the go gauge 513 to move upward when the no-go gauge 514 is pressed, so as to trigger the pressure sensor and control the retraction of the pneumatic telescopic rod.

[0036] like Figure 4-5 As shown, to facilitate adjusting the position of the no-go gauge 514 on the go gauge 513 to match the thickness of the bearing ring, the no-go gauge 514 is further slidably connected to the go gauge 513, and a locking assembly 515 is provided at the upper end of the no-go gauge 514. The locking assembly 515 is used to fix the position of the no-go gauge 514 on the go gauge 513. The locking assembly 515 includes a mounting ring 516 fixedly disposed at the upper end of the no-go gauge 514, and the upper end of the mounting ring 516... The device is provided with a plurality of circumferentially distributed locking teeth 517, the inner wall of which fits against the outer side of the gauge member 513; it also includes a control ring 518 threadedly connected to the mounting ring 516, the inner side of the control ring 518 and the outer side of the locking teeth 517 are provided with mutually fitting pressing surfaces 519, the pressing surfaces 519 are conical, when the control ring 518 moves toward the locking teeth 517, the plurality of locking teeth 517 will deform toward the gauge member 513 to press the gauge member 513.

[0037] When it is necessary to adjust the position of the no-go gauge 514 on the go gauge 513 to accommodate bearing rings of different thicknesses, the control ring 518 is operated first. Since the control ring 518 is threadedly connected to the mounting ring 516, by rotating the control ring 518, it is moved along the thread direction toward the locking tooth 517.

[0038] As the control ring 518 moves, its inner conical pressing surface 519 interacts with the outer conical pressing surface 519 of the locking tooth 517. Because the pressing surface 519 is conical, when the control ring 518 moves closer to the locking tooth 517, it applies an inward pressing force to the locking tooth 517.

[0039] Because the locking teeth 517 are elastically positioned on the upper end of the mounting ring 516 and are circumferentially distributed, when subjected to compressive force, several locking teeth 517 will deform towards the center of the go gauge 513, thereby compressing the go gauge 513. At this time, since the mounting ring 516 is fixedly connected to the no-go gauge 514, the positions of the no-go gauge 514 and the go gauge 513 can be fixed.

[0040] To further improve the friction between the locking tooth 517 and the go gauge 513, rubber can be provided on the inner surface of the locking tooth 517 to increase the friction.

[0041] This structural design, with the no-go gauge 514 and the go gauge 513 slidably connected and equipped with a locking assembly 515, greatly facilitates the adaptation of bearing rings of different thicknesses. In practical applications, simply rotating the control ring 518 and utilizing the interaction between it and the tapered pressing surface 519 of the locking teeth 517 can easily change the pressing force of the locking teeth 517 on the go gauge 513, thereby flexibly adjusting the position of the no-go gauge 514 on the go gauge 513.

[0042] Furthermore, to facilitate the replacement of the cylindrical go gauge 513 and no-go gauge 514, the go gauge 513 is fixed to the connecting rod 512 with bolts; the go gauge 513 and the connecting rod 512 are slidably connected, and a spring is sleeved between the connecting rod 512 and the go gauge 513. Through the above structure, the damage to the material caused by hard contact between the go gauge 513 or the no-go gauge 514 and the bearing ring can be avoided.

[0043] Meanwhile, a rejection assembly is also installed on the frame 1 along the conveyor track 20. The rejection assembly is located one station before the discharge mechanism 4 and can reject unqualified materials.

[0044] Specifically, the rejection assembly is an existing mechanism, which can be a pusher cylinder, thereby pushing the unqualified material away from the conveyor track 20. Example 2

[0045] like Figure 6-7 As shown, based on Embodiment 1, in order to achieve cleanliness of the inner side of the bearing race and thus ensure the accuracy of the test, a cleaning mechanism 6 located below the through hole 22 is provided on the frame 1. The cleaning mechanism 6 is used to clean the inner wall of the bearing race when the bearing race reaches below the go / no-go gauge assembly 51.

[0046] The cleaning mechanism 6 includes a support frame 60 located below the frame 1. A sliding frame 61 connected to a pneumatic lifting rod 62 is provided on the support frame 60. A cleaning head 64 is rotatably mounted on the sliding frame 61. The cleaning head 64 is connected to a drive motor 63. The drive motor 63 is used to drive the cleaning head 64 to rotate to clean the inner wall of the bearing ring when the cleaning head 64 is inserted into the bearing ring.

[0047] The cleaning head 64 includes a rotating shaft 641 connected to the output shaft of the drive motor 63. A movable plate 642 is slidably mounted on the rotating shaft 641. A spring is provided between the movable plate 642 and the sliding frame 61. Several cleaning plates 643 are slidably mounted around the movable plate 642. A spring is provided between the cleaning plates 643 and the movable plate 642. The several cleaning plates 643 are arranged perpendicular to the sliding frame 61 to form a cylindrical structure, and soft brushes are provided on the outer side of the cleaning plates 643.

[0048] When the bearing race moves with the conveying mechanism 2 to below the go / no-go gauge assembly 51, the cleaning mechanism 6 begins to operate. First, the pneumatic lifting rod 62 connected to the support frame 60 located below the frame 1 is activated, pushing the sliding frame 61 upward. As the sliding frame 61 rises, the cleaning head 64, which is rotatably mounted on it, gradually approaches and extends into the bearing race.

[0049] At this time, the drive motor 63 connected to the cleaning head 64 is turned on, and the drive motor 63 drives the rotating shaft 641 connected to its output shaft to rotate. During the rotation of the rotating shaft 641, several cleaning plates 643, which are also connected by springs around the moving plate 642, overcome the spring resistance and unfold vertically along the sliding frame 61 under the action of the moving plate 642 sliding outward, forming a cylindrical structure and fitting against the inner wall of the bearing ring. The soft brushes set on the outside of the cleaning plates 643 clean the inner wall of the bearing ring as the cleaning plates 643 unfold and fit against the inner wall, and as the rotating shaft 641 rotates, removing any impurities, oil stains, etc. that may be present on the inner wall, thereby ensuring the cleanliness of the inner side of the bearing ring.

[0050] After cleaning is completed, the drive motor 63 stops rotating, the pneumatic lifting rod 62 drives the sliding frame 61 to descend, and the cleaning head 64 exits from the bearing ring and returns to its initial position, waiting to clean the next bearing ring, thus ensuring the accuracy of each inner diameter test.

[0051] The aforementioned structure allows for the cleaning of the inner wall of the bearing race before testing, removing impurities, oil, and other contaminants. Failure to remove these contaminants may affect the contact between the go / no-go gauge assembly 51 and the inner diameter of the bearing race, leading to deviations in the test results. Cleaning ensures that the go / no-go gauge assembly 51 accurately contacts the inner diameter during testing, significantly improving the accuracy of the inner diameter measurement and providing a reliable basis for bearing quality control.

[0052] Secondly, the adaptability and versatility of the equipment are enhanced. The unique structural design of the cleaning head 64 allows it to adapt to bearing rings of different inner diameters. The spring between the moving plate 642 and the cleaning plate 643 allows the cleaning plate 643 to adaptively adjust its position according to the inner diameter of the bearing ring, ensuring that the soft brush always adheres to the inner wall for effective cleaning. This eliminates the need to change to specific cleaning tools for different sized bearing rings, thus expanding the applicability of the cleaning mechanism 6.

[0053] Furthermore, such as Figure 6-7 As shown, it also includes a limiting plate 7 disposed above the through hole 22. The limiting plate 7 is provided with a guide hole 70 coaxial with the go gauge 513. The limiting plate 7 can adjust the gap between itself and the conveying track 20 according to the thickness of the bearing ring. By setting the limiting plate 7, the bearing ring can be limited, thereby preventing the bearing ring from being pushed up and shifting position when the cleaning head 64 is inserted in the direction of the bearing ring.

[0054] Meanwhile, a guide plate 644 extends from the upper end of the cleaning plate 643 toward the center of the rotating shaft 641. Several guide plates 644 are inclined upward to form an arc structure above the top protruding through hole 22. The protruding arc structure forms an arc-shaped protrusion on the conveying track 20, which can play a certain positioning role for the bearing ring.

[0055] First, when the transfer robot 21 moves the bearing ring to below the go / no-go gauge assembly 51, the bearing ring will come into contact with the arc structure as it moves, thereby moving the cleaning head 64 downwards. This allows the bearing ring to smoothly reach below the limit plate 7. Subsequently, under the action of the spring, the arc structure moves upwards and partially inserts into the bearing ring, adjusting the left and right positions of the bearing ring to ensure that the bearing ring is centered in the go / no-go gauge assembly 51 and to prevent positional deviation.

[0056] The go gauge 513 is hollow and has a clearance opening 645 on its lower end face, with a chamfered edge. A cylindrical structure formed by several cleaning plates 643 can be inserted into the go gauge 513 through the clearance opening 645. Since a spring is provided between the moving plate 642 and the sliding frame 61, and the moving plate 642 is slidably mounted on the rotating shaft 641, the moving plate 642 will slide outward along the rotating shaft 641 under the combined action of centrifugal force and spring force.

[0057] Since the go gauge 513 is hollow and has a chamfered clearance opening 645 on its lower end face, the cylindrical structure formed by several cleaning plates 643 can be inserted into the go gauge 513 through the clearance opening 645 during descent, avoiding interference between the go gauge 513 and the cleaning head 64, thus protecting both.

[0058] like Figure 7As shown, in order to ensure that the two proximity switch sensors, the first sensor 530 and the second sensor 531, accurately sense the passage of the go gauge 513 and the stop gauge 514, a sensing head 532 protruding towards the sensor detection end is provided on the stop gauge 514. By adjusting the sensing range and distance of the sensor, the stop gauge 514 can be prevented from interfering with the sensor's sensing.
