Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing ring technology, specifically to a bearing ring roundness dimension testing device. Background Technology
[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. They are essential parts in various mechanical equipment, providing strong support for various shaft parts and ensuring transmission accuracy and service life.
[0003] After the existing bearing rings are processed, the groove dimensions and outer fillet dimensions of the bearing need to be inspected before entering the bearing assembly process. However, the inspection is currently carried out manually, which is very inefficient. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bearing ring roundness dimension testing device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A bearing ring roundness inspection device includes a support plate, on which a liftable pressure roller is mounted. The pressure roller is a cylindrical block inclined inward from top to bottom. Below the pressure roller, a rotating shaft is mounted on the support plate to support the bearing ring. Two rotating shafts are rotatable. A planar cone-shaped rotating roller with a rubber-coated surface is mounted on the rotating shaft. The cross-sectional area of the inner side of the rotating roller is smaller than that of the outer side. A displacement sensor that can move back and forth is mounted on the support plate, with its two probes located on the left and right sides of the bearing ring, respectively.
[0007] Preferably, there are two pressure rollers, and the center lines of the two pressure rollers are on the same straight line as the center lines of the two rotating rollers.
[0008] Preferably, the support plate is provided with a fixed plate located on one side of the rotating roller, and the support plate is provided with a movable plate located on one side of the fixed plate that can move left and right via a cylinder 2. The support plate is also provided with a guide groove for guiding the bearing rings to the fixed plate.
[0009] Preferably, the fixing plate is inclined, and the height of the end away from the rotating roller is lower than the height of the end near the rotating roller.
[0010] Preferably, the maximum distance between the guide groove and the fixed plate is less than the diameter of the bearing ring.
[0011] Preferably, the midpoint between the two probes of the displacement sensor is located at the center of the bearing ring.
[0012] Preferably, the support plate is provided with a cylinder for moving the displacement sensor back and forth, the output end of the cylinder is provided with a carrier plate for mounting the displacement sensor, and the carrier plate is provided with an adjustment plate for precisely adjusting the position of the probes on both sides of the displacement sensor.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention delivers the bearing rings onto two rotating rollers. The pressure rollers descend and press against the bearing rings to limit their movement. A displacement sensor approaches the bearing rings until its two probes are positioned on either side of the bearing rings. The rotation of the rollers causes the bearing rings to rotate, allowing the probes to continuously measure the diameter of the bearing rings. This completes the inspection of the bearing rings' roundness. The invention is highly automated and has significant practical value. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0024] like Figure 1-4 As shown, the bearing ring roundness detection device of this utility model includes a support plate 1, on which a cylinder 3 7 is installed. A pressure roller 8 is provided at the output end of the cylinder 3 7. The cylinder 3 7 drives the pressure roller 8 to rise and fall. A drive motor 5 is installed on the support plate 1. A rotating shaft 9 located below the pressure roller 8 is provided at the output end of the drive motor 5. The rotating shaft 9 is rotatable and has two shafts. A cylinder 1 3 is installed on the support plate 1. A bearing plate is provided at the output end of the cylinder 1 3. A displacement sensor 2 is installed on the bearing plate. The midpoint between the two probes of the displacement sensor 2 is located at the center of the bearing ring, ensuring that the displacement sensor 2 detects the diameter of the bearing ring. The operation of the cylinder 1 3 drives the bearing plate and the displacement sensor 2 to move back and forth, thereby approaching the rotating shaft 9.
[0025] The pressure roller 8 is a cylindrical block that slopes inward from top to bottom. A planar cone-shaped rotating roller 10 with a rubber-coated surface is fitted on the rotating shaft 9. The cross-sectional area of the inner side of the rotating roller 10 is smaller than that of the outer side, ensuring that the pressure roller 8 and the rotating roller 10 can limit the bearing ring. There are two pressure rollers 8, and the center lines of the two pressure rollers 8 and the center lines of the two rotating rollers 10 are on the same straight line. The bearing ring is limited by the two pressure rollers 8 and the two rotating rollers 10, which improves the stability of the limit.
[0026] A fixed plate 13 is provided on the support plate 1, located on one side of the rotating roller 10. A cylinder 6 is installed on the support plate 1. A movable plate 12 is provided at the output end of the cylinder 6, located on one side of the fixed plate 13. The cylinder 6 drives the movable plate 12 to move left and right, thereby conveying the bearing rings on the fixed plate 13 to the two rotating rollers 10. A guide groove 11 is also provided on the support plate 1. The guide groove 11 is used to guide the bearing rings to the fixed plate 13 and then convey them to the detection position by the movement of the movable plate 12. The degree of automation is high. The fixed plate 13 is inclined, and the height of the end away from the rotating roller 10 is lower than the height of the end close to the rotating roller 10, ensuring that the bearing rings will not move onto the rotating roller 10 when the movable plate 12 does not apply force to the bearing rings. The maximum distance between the guide groove 11 and the fixed plate 13 is less than the diameter of the bearing rings, ensuring that the bearing rings will not fall off.
[0027] The support plate 1 is also equipped with a cylinder for driving the drive motor 5 and the fixed plate 13 to rise and fall. Adjusting discs 4 are rotatably mounted on both the left and right sides of the support plate. Each adjusting disc 4 has a threaded rod at its end located within the support plate. Each threaded rod has a threaded block threaded through and slidably connected to the support plate. An adjusting plate is located at the top of the support plate at the end of each threaded block. Another adjusting disc 4 is rotatably mounted on the front side of each adjusting plate. Each adjusting disc 4 has a threaded rod at its end located within the adjusting plate. A threaded block is threaded through and slidably connected to the adjusting plate. These two threaded blocks are respectively connected to the two probes of the displacement sensor 2. The distance between the two adjusting plates is adjusted by the left and right adjusting discs 4, and the position of the probes is adjusted by the two front adjusting discs 4. This allows for large-range position adjustment via the cylinder 3 and small-range position adjustment via the adjusting discs 4, achieving precise adjustment. Adjusting the distance between the two probes and the probes' forward and backward movement, in conjunction with the rising and falling of the rotating roller 10, enables the roundness measurement of bearing rings of different sizes, thereby increasing the applicability of the equipment.
[0028] In use, the bearing ring falls onto the fixed plate 13 through the guide groove 11. The second cylinder 6 drives the moving plate 12 to move left and right, thereby conveying the bearing ring onto the two rotating rollers 10. The third cylinder 7 drives the pressure roller 8 to descend and contact the bearing ring, thereby limiting the bearing ring. The first cylinder 3 and the adjusting plate 4 drive the displacement sensor 2 to approach the bearing ring until the left and right probes of the displacement sensor 2 are located on the left and right sides of the bearing ring. The drive motor 5 drives the rotating shaft 9 to rotate, thereby driving the rotating roller 10 to rotate, and thus driving the bearing ring to rotate. The probe continuously measures the diameter of the bearing ring, thereby completing the detection of the roundness of the bearing ring.
[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
