Description

Technical Field

[0001] This utility model relates to the field of bearing production quality control, and in particular to a bearing testing device for bearing production. Background Technology

[0002] In the field of bearing production quality control, the positioning stability and comprehensiveness of the testing device directly affect the accuracy of product testing. Traditional bearing testing devices suffer from a disconnect between clamping and rotational actions, making it difficult to meet the demands of high-precision testing.

[0003] Traditional devices often use a single clamping structure to fix the bearing. Excessive clamping force can easily cause bearing deformation, while insufficient clamping force can cause the bearing to shift during testing, affecting the accuracy of the test data. Furthermore, clamping cannot synchronously rotate the bearing inner ring, allowing only localized testing and making it difficult to comprehensively check for defects such as roundness and surface finish of the bearing inner ring. This can easily lead to substandard products entering the market.

[0004] Meanwhile, some devices suffer from poor linkage between the clamping and detection components, and the operation process is cumbersome, requiring clamping, positioning, and rotation to be completed step by step, resulting in low detection efficiency. As the accuracy requirements of bearing applications increase, the limitations of traditional devices are becoming increasingly apparent. There is an urgent need to develop a bearing detection device that can simultaneously achieve stable clamping and inner ring rotation to improve the comprehensiveness and efficiency of detection. Utility Model Content

[0005] This application provides a bearing testing device for bearing production, which solves the problems of traditional bearing testing devices in the prior art, such as clamping and rotating cutting, requiring synchronous clamping and a rotating inner ring testing device.

[0006] The technical solution adopted in this application is as follows.

[0007] A bearing inspection device for bearing production includes a worktable, a first support plate, a material transfer device, a pre-inspection device, and an inspection device. The first support plate is disposed on the worktable. The material transfer device moves the bearing located on the first support plate to the next work station. The pre-inspection device is disposed on the first support plate. The inspection device is disposed at the next work station after the pre-inspection device. The inspection device includes a second support plate, a sliding plate, a first moving device, an inspection head, and a pressing component. The second support plate is disposed on the first support plate. The first moving device is disposed on the second support plate. The sliding plate slides on the second support plate. The first moving device moves the sliding plate up and down. The inspection head is disposed on the sliding plate. The pressing component is disposed on the sliding plate.

[0008] As a further improvement to the above technical solution: The pressing component includes a second moving device, a sliding rod, a connecting plate, a pressure roller, and an elastic element; the second moving device is disposed on the second support plate; the connecting plate is disposed on the actuating end of the second moving device; the sliding rod is disposed on the connecting plate; the sliding rod passes through the sliding plate and the connecting plate; the elastic element is sleeved on the sliding rod; one end of the elastic element abuts against the second support plate, and the other end of the elastic element abuts against the connecting plate; the pressure roller is disposed at the bottom of the sliding rod; the pressure roller corresponds to the top of the inner ring of the bearing to be tested.

[0009] A rotating plate is rotatably connected to the first support plate; a rotating device is provided on the worktable; the rotating device drives the rotating plate to rotate; when the pressure roller abuts against the top of the inner ring of the bearing to be tested, the rotating plate drives the inner ring of the bearing to be tested to rotate.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. The synergistic design of the pressing component and the rotating plate completely solves the problems of fragmented clamping and rotation, and localized inspection, inherent in traditional devices. When the pressure roller of the pressing component presses against the top of the bearing inner ring, the elastic element buffers the clamping force, preventing excessive pressure from deforming the bearing. Simultaneously, the rotating device on the worktable drives the rotating plate to rotate, which in turn drives the bearing inner ring to rotate synchronously. This method of simultaneous clamping and rotation allows the inspection head to inspect the entire circumference of the bearing inner ring, rather than being limited to a localized area. This allows for a comprehensive inspection of issues such as roundness deviations and surface defects, preventing the omission of defective products due to localized inspection and significantly improving the reliability of the inspection results. Furthermore, the stable clamping force combined with synchronous rotation ensures no bearing misalignment during inspection, stable contact between the inspection head and the inner ring surface, and significantly improved data acquisition accuracy, meeting the quality control requirements of high-precision bearings.

[0011] 2. By incorporating an elastic element fitted onto the sliding rod of the lower pressure component, with both ends of the elastic element abutting against the second support plate and the connecting plate respectively, a flexible clamping structure is formed. This solves the problem of bearing deformation or misalignment easily caused by traditional single clamping structures. When the pressure roller contacts the inner ring of the bearing, the elastic element can automatically adjust the clamping force according to the bearing specifications, ensuring sufficient fixing force to prevent slippage during rotation while avoiding bearing damage caused by rigid clamping. At the same time, the elastic buffering effect reduces the impact between the pressure roller and the inner ring of the bearing, extending the service life of the pressure roller; the detection head moves stably with the sliding plate without bearing additional impact force, further protecting high-precision detection components, reducing equipment maintenance costs, and improving the overall durability of the device.

[0012] 3. By integrating components such as a first moving device, a second moving device, and a rotating device into the detection unit, the device achieves a streamlined operation of material transfer, pre-inspection, clamping, rotation, and inspection, solving the problems of step-by-step operation and low efficiency in traditional devices. After the material transfer device transports the bearing from the first support plate to the inspection station, the first moving device drives the sliding plate to descend, bringing the inspection head closer to the bearing's inner ring. Simultaneously, the second moving device drives the connecting plate to move downward, and the pressure roller presses against the inner ring to complete the clamping. The rotating device synchronously drives the rotating plate and the inner ring to rotate, and the inspection head collects full-circumference data in real time. The entire process requires no manual intervention, and the actions are seamlessly connected, significantly shortening the inspection cycle for a single bearing. Attached Figure Description

[0017] This application provides a bearing testing device for bearing production, which solves the problems of traditional bearing testing devices in the prior art that require simultaneous pressing and rotating cutting, and require a rotating inner ring testing device.

[0018] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows: To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Workbench 1 and base support: Workbench 1 is a high-strength flat plate with a surface precision machined to ensure flatness; a first support plate 2 is fixed on workbench 1, and the first support plate 2 is divided into pre-inspection station and precision inspection station along the bearing rotation direction. The pre-inspection device 54 is fixed at the pre-inspection station for preliminary screening of the bearing appearance and base dimensions; the material transfer device 3 is installed on one side of the first support plate 2 and can drive the bearing to move smoothly between the stations.

[0020] Precision testing device 5 assembly: A second support plate 51 is fixed on the first support plate 2 at the precision testing station. The second support plate 51 is arranged vertically. A first moving device 53 is installed on the second support plate 51. The working end of the first moving device 53 is connected to a sliding plate 52. The sliding plate 52 can slide up and down along the second support plate 51. A testing head 54 is fixed on the sliding plate 52. The testing end of the testing head 54 faces the inner ring of the bearing to be tested and is used to collect the inner ring accuracy data.

[0021] The pressing component 55 is assembled with the rotating structure: the second moving device 551 of the pressing component 55 is fixed on the second support plate 51, and its working end is connected to the connecting plate 553; a sliding rod 552 is fixed on the connecting plate 553, the sliding rod 552 passes vertically through the sliding plate 52 and the connecting plate 553, and a pressure roller 554 is installed at the bottom of the sliding rod 552, the pressure roller 554 corresponds to the top position of the inner ring of the bearing to be tested; an elastic element 555 is sleeved on the sliding rod 552, and the two ends of the elastic element 555 abut against the second support plate 51 and the connecting plate 553 respectively; a rotating plate 6 is rotatably connected to the first support plate 2, the rotating plate 6 is located below the bearing to be tested, and a rotating device 7 is installed on the worktable 1, the rotating device 7 drives the rotating plate 6 to rotate through the transmission structure.

[0022] Coordinated adjustment of clamping and rotation: Place the standard bearing on the rotating plate 6, start the second moving device 551 to drive the connecting plate 553 to move down, so that the pressure roller 554 abuts against the top of the inner ring of the bearing, observe the compression state of the elastic element 555, and ensure that the clamping force is appropriate (the bearing is not deformed and not loose); at the same time, start the rotating device 7 to verify that when the rotating plate 6 drives the inner ring of the bearing to rotate, the pressure roller 554 rotates synchronously with the bearing and there is no slippage, and the test head 54 can stably fit against the surface of the inner ring.

[0023] Inspection accuracy calibration: Use a standard precision bearing to calibrate the inspection head 54, adjust the position and sensitivity of the inspection head 54 to ensure that the inspection data can accurately reflect the inner ring roundness and surface finish deviation, and the error is controlled within the allowable range; test the connection between the pre-inspection device 54 and the precision inspection device 5 to ensure that the out-of-tolerance bearings screened out by the pre-inspection can be diverted by the material transfer device 3 and do not enter the precision inspection station.

[0024] Material transfer coordination debugging: Start the material transfer device 3 and test the accuracy of its movement of the bearing between the pre-detection station and the precision detection station to ensure that the bearing can be accurately positioned on the rotating plate 6 without deviation or jamming, and that the actions of each station are smoothly connected.

[0025] The bearing is conveyed to the initial position of the first support plate 2 by the feeding mechanism. The transfer device 3 drives the bearing to the pre-inspection station. The pre-inspection device 54 inspects the basic indicators such as the appearance and outer diameter of the bearing, and screens out bearings with damaged appearance and seriously out-of-tolerance dimensions. The transfer device 3 then conveys them to the non-conforming product area, while qualified bearings enter the next stage.

[0026] The material transfer device 3 transports the pre-inspected qualified bearings to the precision inspection station, aligning the inner ring of the bearing with the pressure roller 554 directly below, while the bottom of the bearing is placed stably on the rotating plate 6, thus completing the positioning.

[0027] The first moving device 53 drives the sliding plate 52 to move down, so that the detection head 54 approaches the inner ring of the bearing until the detection end is in contact with the surface of the inner ring. The second moving device 551 is activated simultaneously, which drives the connecting plate 553 to move down. The sliding rod 552 moves down with the connecting plate 553, and the pressure roller 554 presses against the top of the inner ring of the bearing. The elastic element 555 automatically adjusts the clamping force according to the bearing specifications to ensure that the bearing is stable and free from deformation. Start the rotating device 7, which drives the rotating plate 6 to rotate. The rotating plate 6 drives the inner ring of the bearing to rotate synchronously, and the pressure roller 554 rotates with the inner ring. The detection head 54 collects roundness and surface finish data of the bearing inner ring in real time during rotation, and transmits the data to the control system for analysis.

[0028] After the test is completed, the control system determines whether the bearing is qualified based on the collected data: Qualified bearings: The first moving device 53 drives the sliding plate 52 to move upward, and the detection head 54 disengages from the inner ring; the second moving device 551 drives the connecting plate 553 to move upward, and the pressure roller 554 leaves the inner ring; the material transfer device 3 transports the qualified bearings to the qualified product area. Defective bearings: The material transfer device 3 transports them to the defective product area and stores them separately from the defective products screened out in the pre-inspection. After all actions are completed, the material transfer device 3 resets, ready for the next bearing inspection.

[0029] When different specifications of bearings need to be tested, the initial height of the connecting plate 553 is adjusted by the second moving device 551 to match the height of the bearing inner ring. If the bearing inner diameter changes, the pressure roller 554 of the corresponding size is replaced. The pressure roller 554 and the sliding rod 552 are detachably connected, making replacement convenient. The wear of the pressure roller 554 is checked regularly, and it is replaced in time if the wear is serious. The surface of the detection head 54 is cleaned to ensure detection accuracy. Lubricating oil is added to the sliding parts of the rotating device 7 and the moving device regularly to ensure smooth operation of the equipment.
