Description

Technical Field

[0001] This utility model relates to the field of bearing production quality inspection, and in particular to a device for inspecting bearings with a cleaning function. Background Technology

[0002] In the field of bearing production quality inspection, accurate testing and efficient operation are the core to ensuring product qualification rate. Traditional bearing testing devices have problems such as functional fragmentation and easily damaged testing components.

[0003] Traditional testing devices often lack integrated cleaning functions, and impurities such as oil and iron filings on the bearing surface can easily affect testing accuracy and lead to misjudgments. Furthermore, the lack of a pre-inspection process, coupled with the direct use of a high-precision testing head to measure the bearing's inner diameter, can easily cause wear and damage to the testing head if the bearing's dimensions are out of tolerance, increasing equipment maintenance costs.

[0004] Meanwhile, the traditional equipment suffers from poor coordination in the loading, transferring, testing, and unloading processes, relying heavily on manual assistance or unidirectional material transfer structures. This makes it impossible to achieve simultaneous multi-station operations, resulting in low testing efficiency. Furthermore, the cleaning and testing components in some units are relatively fixed, lacking adaptability and failing to meet the testing requirements of bearings of different specifications, further limiting production efficiency.

[0005] As the bearing manufacturing industry develops towards large-scale and high-precision production, the shortcomings of traditional equipment, such as limited functionality, high inspection risk, and low efficiency, are no longer suitable for production needs. Therefore, developing a bearing inspection device that integrates cleaning, pre-inspection, precise inspection, and efficient material transfer functions has become an urgent need to improve inspection reliability and efficiency. Utility Model Content

[0006] This application provides a bearing inspection device with cleaning capabilities, which solves the problem that traditional bearing inspection devices in the prior art lack pre-inspection cleaning and require the integration of a multi-functional and efficient inspection device.

[0007] The technical solution adopted in this application is as follows.

[0008] A bearing inspection device with cleaning function includes a worktable, a loading device, a transferring device, a cleaning device, a pre-inspection device, an inspection device, and a unloading device. The loading device is located on one side of the worktable, and the unloading device is located on the other side of the worktable. A support plate is provided on the worktable. The cleaning device, the pre-inspection device, and the inspection device are sequentially arranged on the support plate. The diameter of the inspection head of the pre-inspection device is larger than that of the inspection head of the inspection device. The pre-inspection device pre-inspects the inner diameter of the bearing to prevent damage to the inspection device.

[0009] As a further improvement to the above technical solution: a support rod is provided on the support plate; a first plate is provided on the support rod; a sliding plate is slidably connected to the support rod; the cleaning device includes a liquid outlet and a cover; the cover is provided on the sliding plate; the liquid outlet is provided on the support plate; the cover corresponds to the liquid outlet.

[0010] As a further improvement to the above technical solution: the pre-detection device is mounted on the slide plate; the pre-detection device moves synchronously with the cover.

[0011] As a further improvement to the above technical solution: the material transfer device includes a second plate, a third plate, a fourth plate, a first pushing member, a second pushing member, and a moving plate; the second plate is disposed on the worktable; the third plate slides on the second plate; the fourth plate slides on the third plate; the sliding directions of the third plate and the fourth plate are perpendicular; the first pushing member drives the third plate to slide; the second pushing member drives the fourth plate to slide; the moving plate is disposed on the fourth plate; the moving plate has slots corresponding to the bearings; a plurality of slots are provided; the spacing between the slots is consistent with the distance between the pre-detection device and the detection device.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. By integrating a complete process of cleaning, pre-inspection, and precision testing, this system completely solves the problems of low accuracy and easily damaged detection heads caused by the lack of cleaning and pre-inspection in traditional devices. The cleaning device's housing and outlet work together to specifically clean the bearing surface, removing impurities such as oil and iron filings, preventing them from affecting subsequent test data and ensuring test accuracy from the source, reducing misjudgments caused by impurities. The pre-inspection device has a larger detection head diameter than the precision testing device, allowing for preliminary screening of the bearing's inner diameter. If the bearing size is out of tolerance, the pre-inspection head will identify and intercept it in advance, preventing out-of-tolerance bearings from entering the precision testing stage and damaging the high-precision detection head. This significantly reduces the risk of wear on the testing components and reduces equipment maintenance costs. This "clean first, then pre-screen, then precision test" process design not only improves the reliability of the test results but also extends the service life of the high-precision testing components, adapting to the high-precision testing needs of bearings.

[0013] 2. The collaborative design of the material transfer device and multi-station layout solves the problems of poor coordination and low efficiency in traditional devices. The cleaning device, pre-inspection device, and inspection device are arranged sequentially on the worktable, forming a continuous inspection production line. The third and fourth plates of the material transfer device slide vertically, and in conjunction with the first and second pushing components, they enable flexible two-dimensional material transfer. The spacing of the slots on the moving plates matches the spacing of the pre-inspection and inspection devices, allowing multiple bearings to be switched simultaneously between different stations. This design seamlessly connects the loading, cleaning, pre-inspection, precision inspection, and unloading processes, enabling synchronous operation at multiple stations and avoiding the efficiency bottlenecks of manual assistance or single-direction material transfer. Simultaneously, the material transfer action is highly automated, requiring no manual intervention, significantly shortening the inspection cycle of a single bearing and meeting the high-efficiency inspection requirements of large-scale production.

[0014] 3. Because the cleaning and pre-inspection devices are slidably connected to the support rod via a sliding plate, their positions can be adjusted according to the size of different bearings, solving the problem of poor adaptability in traditional devices. The cleaning device's housing moves with the sliding plate, precisely covering bearings of different diameters and ensuring thorough cleaning. The pre-inspection device moves synchronously, precisely aligning with the inner diameter of different bearings without requiring replacement of pre-inspection components. Furthermore, the slots on the moving plate can accommodate various bearing outer diameters, and the pushing stroke of the transfer device can be adjusted via control parameters, further expanding the device's applicability. This adjustable design allows a single device to meet the inspection needs of different bearing sizes, eliminating the need for separate devices for each size, reducing equipment investment costs, and improving production flexibility.

[0019] This application provides a bearing inspection device with cleaning capabilities, which solves the problem that traditional bearing inspection devices in the prior art lack pre-inspection cleaning and require the integration of a multi-functional and efficient inspection device.

[0020] 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.

[0021] Workbench 1 and basic layout: Workbench 1 is a cast iron plate with a ground surface; a feeding device 2 is installed on one side and a discharging device 7 is installed on the other side; a support plate 11 is fixed in the middle of workbench 1, and a cleaning device 4, a pre-inspection device 65, and an inspection device 6 are installed on the support plate 11 in sequence along the bearing rotation direction, and the spacing between the three is matched with the spacing of the slot 361 of the transfer device 3.

[0022] Cleaning device 4 assembly: support rod 12 is fixed on support plate 11, first plate 13 is installed at the top of support rod 12, and slide plate 14 is slidably connected in the middle; cover 42 is fixed at the bottom of slide plate 14, and liquid outlet 41 is opened on support plate 11 corresponding to the position of cover 42; slide plate 14 can slide up and down along support rod 12, driving cover 42 to rise and fall, so as to cover and clean the bearing and move it away to make way.

[0023] Pre-inspection and inspection device 6 assembly: The pre-inspection device 65 is fixed on the slide plate 14, and its inspection head diameter is slightly larger than that of the precision inspection head of the inspection device 6; the inspection device 6 is fixed on the support plate 11, and both are connected to the data acquisition system, which can transmit inspection data in real time; the pre-inspection device 65 is used for preliminary screening of bearings with out-of-tolerance inner diameter, and the inspection device 6 is responsible for accurately measuring the inner diameter of qualified bearings.

[0024] Material transfer device 3 assembly: A second plate 31 is fixed on one side of the workbench 1, a third plate 32 is slidably installed on the second plate 31, and a fourth plate 33 is slidably installed on the third plate 32; a first pushing member 34 is installed on the side of the second plate 31 to drive the third plate 32 to slide; a second pushing member 35 is installed on the side of the third plate 32 to drive the fourth plate 33 to slide; a moving plate 36 is fixed on the top of the fourth plate 33, and multiple sets of slots 361 are opened on the moving plate 36, the spacing of the slots 361 being consistent with the spacing of the cleaning, pre-inspection, and inspection devices 6.

[0025] Cleaning effect adjustment: Place the standard bearing into the slot 361, start the cleaning device 4, adjust the cleaning fluid pressure and the lifting speed of the cover 42 to ensure that there is no oil or iron filings on the bearing surface after cleaning, and control the cleaning time within a reasonable range. Inspection accuracy calibration: The pre-inspection device 65 and the inspection device 6 are calibrated with bearings of standard inner diameter, and the size threshold of the pre-inspection is set to ensure that the pre-inspection head can accurately intercept bearings that exceed the tolerance, and the measurement error of the inspection device 6 is controlled within the allowable range; Material transfer coordination debugging: Start the material transfer device 3 and test the sliding coordination between the third plate 32 and the fourth plate 33 to ensure that the moving plate 36 can accurately transport the bearing to the cleaning, pre-inspection and inspection stations without jamming or positioning deviation, and that the connection between each link is smooth.

[0026] The feeding device 2 automatically sorts the bearings and transports them to the initial position of the workbench 1; the fourth plate 33 of the transfer device 3 slides to the initial position under the action of the second pusher 35, the slot 361 of the moving plate 36 aligns with the bearing, and the third plate 32 moves under the action of the first pusher 34, so that the bearing is inserted into the slot 361, completing the initial positioning.

[0027] The transfer device 3 drives the moving plate 36 to transport the bearing to the cleaning station; the slide plate 14 descends along the support rod 12, the cover 42 covers the bearing, and the liquid outlet 41 sprays high-pressure cleaning fluid to clean the bearing surface; after cleaning, the slide plate 14 rises, driving the cover 42 and the pre-inspection device 65 to rise, and the transfer device 3 transports the bearing to the pre-inspection station.

[0028] The transfer device 3 precisely positions the bearing below the pre-inspection device 65. The slide plate 14 descends, causing the inspection head of the pre-inspection device 65 to insert into the inner diameter of the bearing. If the inspection data shows that the inner diameter is out of tolerance, the system determines that it is unqualified and will be subsequently transported to the unqualified channel of the unloading device 7. If the size is qualified, the slide plate 14 rises, and the transfer device 3 transports the bearing to the inspection station.

[0029] After the bearing arrives at the inspection station, the precision inspection head of the inspection device 6 is automatically inserted into the inner diameter of the bearing to perform high-precision dimensional measurement; the data acquisition system records the inspection results, and if they meet the standards, they are judged as qualified, otherwise they are judged as unqualified.

[0030] The transfer device 3 transports the bearings that have completed the inspection to the unloading station; according to the inspection results, qualified bearings are transported to the qualified channel of the unloading device 7 and sent into the finished product basket; unqualified bearings are transported to the unqualified channel and sent into the rework basket; the transfer device 3 is reset and ready for the next round of inspection.

[0031] When different specifications of bearings need to be tested, only the moving plate 36 needs to be replaced, the size parameters of the pre-testing device 65 and the testing device 6 need to be adjusted, and the sliding plate 14 needs to be used to adjust the position of the cover 42 and the pre-testing device 65. No other parts need to be disassembled, and the adaptation and adjustment time is short.

[0032] After the daily inspection is completed, shut off the cleaning fluid supply system, clean the residual impurities at the outlet 41 to prevent blockage; check whether the detection head of the pre-inspection and detection device 6 is worn, and replace it in time if there is wear; clean the slot 361 of the moving plate 36 to remove residual cleaning fluid or impurities to ensure accurate positioning in the future; regularly check the pushing and sliding parts of the transfer device 3, add lubricating oil to ensure smooth sliding.
