Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing detection, and in particular to a rolling bearing sealing piece detection device. BACKGROUND

[0002] After the bearing production and processing is completed, it usually needs to go through multiple detections before being delivered, including the detection of the connection condition of the bearing sealing piece, which needs to be confirmed through the detection of the cover turning and cover dropping. With the increasing maturity of automation and the increasing stability of product quality, the demand for automatic detection of closed bearings turning and dropping during batch production is increasingly urgent, especially in the process of closed deep groove ball bearing pressing, which cannot get rid of the inefficient work mode of manual cover turning and dropping. More importantly, the application range of ordinary closed rolling bearings is becoming wider and wider, and the demand is becoming larger and larger, so the detection and control of the cover turning and dropping of the closed bearing is particularly important and is the key link affecting the assembly efficiency of the product. SUMMARY

[0003] In view of the deficiencies of the prior art, the present application provides a rolling bearing sealing piece detection device, which has a simple structure, can efficiently detect the connection condition of the bearing sealing piece, has high automation degree and good use effect.

[0004] To achieve the above-mentioned purpose, the present application provides a rolling bearing sealing piece detection device, which comprises a base, the base is provided with baffles on both sides, one of the baffles is fixedly arranged on the base, and the other baffle is connected with a sliding motor for driving the baffle to slide, the opposite sides of the two baffles are formed with arc-shaped grooves, and the arc-shaped grooves on the two baffles are combined to form a clamping groove for mounting a bearing to be detected, a lifting frame is arranged on the base, a movable pressing plate is slidably arranged on the lifting frame in the height direction, a rotating shaft and a rotating motor for driving the rotating shaft to rotate are arranged on the movable pressing plate, a pressing cover is connected with the rotating shaft, the bottom surface of the pressing cover is formed with a suction groove in the circumferential direction, a suction ring for abutting on the bearing sealing piece is arranged in the suction groove, the suction ring is hollow, a plurality of suction holes are formed on the side of the suction ring facing the clamping groove, and a suction valve is arranged on the pressing cover and communicates with the suction ring.

[0005] The advantages of this setup are as follows: With this configuration, the bearing under test is positioned by the movable baffle pushing against the fixed baffle. A grating sensor can be used to identify whether it is properly installed. Once installed, the movable pressure plate is driven by the drive unit to slide towards the bearing under test. Preferably, a displacement sensor can be installed on the movable pressure plate. The displacement sensor can control the stopping of the drive unit and the activation of the suction valve. The displacement sensor can sense whether the movable pressure plate is in position and control its descent speed. Simultaneously, the displacement sensor can control the working state of the suction valve. When the movable pressure plate is detected to be in position, the power unit can automatically control and adjust the movable air pressure according to the required displacement, slowly pushing the movable pressure plate, effectively avoiding damage to the dust cover due to excessive displacement and reducing the defect rate of finished products. When the movable pressure plate reaches the designated position, the displacement sensor activates the suction valve through signal transmission to control the air pressure, allowing the adsorption ring to effectively adhere to the bearing through the air holes. The entire testing process requires no manual control of the power unit; only the main switch needs to be controlled, making it highly automated. The adsorption ring is brought into contact with the seal of the bearing under test. A vacuum valve is used to evacuate the surface of the seal between the gland and the bearing, and then the bearing is held in place by the air pressure. Preferably, the material of the adsorption ring is nitrile rubber (NBR). The effective width of the rubber seal is consistent with or slightly larger than the bending width of the bearing seal by 1-2 mm. The rubber seal is attached to the adsorption groove of the gland with a special soft adhesive. The surface of the adsorption ring is uniformly perforated with 1mm diameter through holes. The center diameter of these holes aligns with the center diameter of the bearing seal plane under test, maximizing adsorption force. After adsorption, the movable pressure plate can be raised and lowered via a drive mechanism to drag the seal ring for a cap-drop test. The pulling force for the cap-drop test must be calculated based on the sealing structure of the bearing under test to match the pull-out force of the seal after pressing, thus better evaluating the cap quality. Further, a rotating motor is used to perform a cap-rotation test on the seal ring. The torque (rotation parameter) of the motor must be calculated based on the sealing structure of the bearing under test. This structure is simple, efficiently performs cap-rotation and cap-drop tests, has a high degree of automation, reduces labor costs, and demonstrates excellent performance.

[0006] As a further feature of the present invention, the lifting frame includes a support column and a fixed pressure plate. The movable pressure plate is slidably engaged with the support column, and the fixed pressure plate is connected to the support column. The fixed pressure plate is disposed above the movable pressure plate, and drive motors are respectively disposed on both sides of the fixed pressure plate. The output ends of the drive motors are respectively fixedly connected to the movable pressure plate.

[0007] The advantages of this design are: it effectively improves the stability of the moving pressure plate lifting mechanism, enhances the overall structural performance, and is simple and easy to implement.

[0008] As a further feature of the present invention, a support spring is sleeved on the support column, and the support spring is disposed between the movable pressure plate and the base.

[0009] The beneficial effects of this setting are: by using this setting, the movable pressure plate can automatically level itself based on its own weight and the reaction force of the supporting spring, ensuring the horizontal contact of the movable pressure plate, improving the accuracy of the overall structural test, and improving the overall structural performance.

[0010] As a further feature of the present invention, a positioning flange for abutting against the inner circle of the inner ring of the bearing to be tested is formed on the lower end face of the pressure cap.

[0011] The beneficial effect of this design is that it ensures the stability of the contact points and improves the overall structural performance.

[0012] As a further feature of the present invention, the baffle includes a connecting part, a first positioning part and a second positioning part. The first positioning part and the second positioning part are respectively disposed on both sides of the connecting part. The first positioning part is disposed higher than the second positioning part. The arc-shaped groove is disposed on the second positioning part. The first positioning part has a positioning protrusion for abutting against the upper end face of the bearing to be tested, corresponding to the position of the arc-shaped groove.

[0013] The beneficial effects of this configuration are: by setting the baffle in this form, the bearing to be tested is clamped by the second positioning part, while the first positioning part can abut against the end face of the bearing to be tested, thereby positioning the bearing in the axial direction, improving the stability of the positioning, and improving the overall structural performance.

[0014] As a further feature of the present invention, an anti-slip pad is provided in the arc-shaped groove of the baffle.

[0015] The beneficial effects of this design are: it can effectively prevent the arc groove of the baffle from scratching the bearing, while also better positioning the bearing, increasing the contact area, effectively preventing the bearing from running off-center, and resulting in better performance.

One baffle 5 is fixedly mounted on the base 1, and the other baffle 5 is connected to a sliding motor for driving the baffle 5 to slide. An arc-shaped groove is formed on the opposite side of the two baffles 5. The arc-shaped grooves on the two baffles 5 combine to form a clamping groove for installing the bearing to be tested. A lifting frame is mounted on the base 1, and a movable pressure plate 23 is slidably mounted on the lifting frame along the height direction. A rotating shaft and a rotary motor 3 for driving the rotating shaft are mounted on the movable pressure plate 23. A pressure cover 4 is connected to the rotating shaft. An adsorption groove is formed circumferentially on the bottom surface of the pressure cover 4. An adsorption ring 41 for adhering to the bearing seal is provided in the adsorption groove. The adsorption ring 41 is hollow, and several suction holes are formed on the side of the adsorption ring 41 facing the clamping groove. An air extraction valve 42 is provided on the pressure cover 4, and the air extraction valve 42 is connected to the adsorption ring 41. The beneficial effects of this setup are as follows: With this setup, the bearing under test is positioned by the movable baffle 5 pushing against the fixed baffle 5. A grating sensor can be used to identify whether the bearing is properly installed. Once installed, the movable pressure plate 23 is driven by the drive unit to slide towards the bearing under test. Preferably, a displacement sensor can be installed on the movable pressure plate 23. The displacement sensor can control the stopping of the drive unit and the activation of the suction valve 42. The displacement sensor can sense whether the movable pressure plate 23 is in position and control its descent speed. Simultaneously, the displacement sensor can control the working state of the suction valve 42. When the movable pressure plate 23 is detected to be in position, the power unit can automatically control and adjust the air pressure according to the required displacement, slowly pushing the movable pressure plate 23, effectively avoiding damage to the dust cover due to excessive displacement and reducing the defect rate of finished products. When the movable pressure plate 23 reaches the designated position, the displacement sensor activates the suction valve 42 through signal transmission to control the air pressure, allowing the adsorption ring 41 to effectively adsorb the bearing through the air holes. The entire testing process requires no manual control of the power unit; only the main switch needs to be controlled, making it highly automated. The adsorption ring 41 is pressed against the seal of the bearing to be tested. The vacuum valve 42 is used to evacuate the seal surface between the pressure cap 4 and the bearing, thereby using air pressure to hold the bearing in place. Preferably, the material of the adsorption ring 41 is nitrile rubber (NBR). The effective width of the rubber seal is consistent with or slightly larger than the bending width of the bearing seal by 1-2 mm. The rubber seal is adhered to the adsorption groove of the pressure cap 4 with a special soft adhesive.The surface of the adsorption ring 41 is uniformly provided with through holes of 1mm diameter. The center diameter of the through holes is consistent with the center diameter of the plane of the bearing seal under test, so as to make its adsorption force greater. After the adsorption action is completed, the movable pressure plate 23 can be raised and lowered by the drive component to drag the seal ring for cap removal test. The pulling force for cap removal test should be calculated according to the sealing structure of the bearing under test to match the pull-out force of the seal after pressing, so as to better evaluate the quality of the cap 4 of the bearing under test. Further, the motor is rotated to perform a cap rotation test on the seal ring. Here, the torque (rotation parameter) of the motor should be calculated according to the sealing structure of the bearing under test. This structure is simple, can efficiently perform cap rotation and cap removal tests, has a high degree of automation, reduces labor costs, and has good usage effect.

The beneficial effect of this arrangement is that the movable pressure plate 23 automatically levels itself based on its own weight and the reaction force of the support spring 25, ensuring the horizontal contact of the movable pressure plate 23, improving the accuracy of overall structural testing, and enhancing the overall structural performance.

[0024] As a further feature of this embodiment, a positioning flange 43 for abutting against the inner circle of the bearing to be tested is formed on the lower end face of the pressure cap 4. The beneficial effect of this feature is that it ensures the stability of the contact position and improves the overall structural performance.

The first positioning portion 52 has a positioning protrusion corresponding to the position of the arc-shaped groove for abutting against the upper end face of the bearing to be tested. The beneficial effect of this configuration is that by setting the baffle 5 in this form, the bearing to be tested is clamped by the second positioning portion 53, and the first positioning portion 52 can abut against the end face of the bearing to be tested, thereby positioning the bearing in the axial direction, improving the stability of the positioning, and improving the overall structural performance.
