[0002] The main function of a bearing is to support a rotating mechanical body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. A bearing includes a bearing inner ring, a cage, rolling elements, and a bearing outer ring. The bearing inner ring and the outer ring are collectively referred to as the bearing rings. A bearing ring is an annular part of a radial rolling bearing with one or more raceways.

[0003] After the production of the bearing rings is completed, the bearings need to be measured to detect the machining precision of the bearing rings. When measuring, the staff will rotate the rings to measure the dimensional precision at different positions of the rings, which causes the rings to easily slide and fall on the measuring table, thus affecting the measurement efficiency. Summary of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a device for measuring the precision of bearing inner and outer rings, which solves the problem that the bearing rings are prone to sliding and falling during measurement, thus affecting the measurement efficiency of the rings.

[0005] To achieve the above object, the utility model provides the following technical solution: A device for measuring the precision of bearing inner and outer rings, including a base, two fixed rods are connected to both sides of the base, a rotating plate is rotatably connected to the base through the fixed rods, a vertical rod is connected to the rear of the base, a hinge is connected to the front of the base, a measuring table is rotatably connected to the base through the hinge, a placing table is connected to the measuring table, guide grooves are opened on both the measuring table and the placing table, a grip is connected to the measuring table, and a fixed frame is connected to one side of the measuring table;

[0006] A motor is installed on the fixed frame, a threaded rod is connected to the output shaft of the motor, a sliding block is installed on the threaded rod, a threaded sleeve is installed on the sliding block, a fixing plate is connected to the sliding block, a first roller is installed on the fixing plate, a cross bar is slidably connected to the vertical rod, a sliding sleeve is slidably connected to the cross bar, a fixed clamp is rotatably connected to the sliding sleeve, and a measuring gauge is installed on the fixed clamp.

[0007] As a further solution of the utility model: The threaded rod is rotatably connected in the guide groove and has threads with opposite directions at both ends. The threaded sleeve is in threaded cooperation with the threaded rod, and the sliding block slides in the guide groove.

[0008] As a further solution of the utility model: Connecting rods are connected to both sides of the fixing plate, side plates are rotatably connected to the connecting rods, second rollers are installed on the side plates, and torsion springs are connected to both sides of the side plates. One end of the torsion spring is connected to the fixing plate.

[0009] As a further solution of the utility model: an anti-slip rubber sleeve is sleeved on the grip, and fastening bolts are threadedly connected to the cross bar, the sliding sleeve and the fixing clip.

[0010] As a further solution of the utility model: fixing bolts are connected to both sides of the measuring table, a sliding groove is formed on the rotating plate, the fixing bolts slide in the sliding groove, and a threaded cap is threadedly connected to the fixing bolts.

[0011] As a further solution of the utility model: fixing suction cups are installed below the base, and the four fixing suction cups are evenly distributed below the base in a rectangular array.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For this bearing inner and outer ring precision measuring device, by setting the threaded rod, the sliding block, the threaded sleeve, the fixing plate, the side plate, the first roller and the second roller, when the motor rotates the threaded rod, the sliding block can move along the threaded rod through the threaded fit between the threaded sleeve and the threaded rod, so that the sliding block drives the two fixing plates to move towards each other, making the first roller on the fixing plate contact with the inner diameter of the ring, thereby tightly clamping the bearing ring and preventing the ring from sliding and falling. When in contact, the inner diameter of the ring will push the second roller, causing the side plate to rotate, so that both the first roller and the second roller contact with the inner diameter of the ring, thereby assisting the staff to rotate the ring through the rolling first roller and second roller to measure different positions of the ring.

[0014] 2. For this bearing inner and outer ring precision measuring device, by setting the rotating plate, the sliding groove, the fixing bolt and the threaded cap, by loosening the threaded cap, the staff can rotate the measuring table. When the measuring table rotates, the fixing bolt will slide in the sliding groove and simultaneously rotate the rotating plate, thereby adjusting the angle of the measuring table to facilitate the staff to observe the data. By tightening the threaded cap, the threaded cap is in close contact with the rotating plate, thereby fixing the measuring table and preventing the measuring table from accidentally rotating and affecting the measurement.

[0020] The technical solution of this patent will be further described in detail below in conjunction with the specific implementation mode.

[0021] As Figures 1-4 shown, the utility model provides a technical solution: a device for measuring the precision of the inner and outer rings of a bearing, including a base 1, fixed rods 2 are connected to both sides of the base 1, the base 1 is rotatably connected to a rotating plate 3 through the fixed rods 2, a vertical rod 4 is connected to the rear of the base 1, a hinge 5 is connected to the front of the base 1, and a fixed suction cup 29 is installed below the base 1. The four fixed suction cups 29 are evenly distributed in a rectangular array below the base 1. The base 1 is fixed by adsorbing the tabletop through the fixed suction cup 29, so as to prevent the base 1 from sliding during measurement and affecting the measurement.

[0022] The base 1 is rotatably connected to a measuring table 6 through the hinge 5. Fixed bolts 26 are connected to both sides of the measuring table 6. A chute 27 is opened on the rotating plate 3. The fixed bolts 26 slide in the chute 27. A threaded nut 28 is threadedly connected to the fixed bolts 26. By the sliding of the fixed bolts 26 in the chute 27, the rotating plate 3 can be pushed to rotate when the measuring table 6 rotates, so that the staff can adjust the viewing angle of the measuring table 6, improving the practicability.

[0023] A placing table 7 is connected to the measuring table 6. Guide grooves 8 are opened on both the measuring table 6 and the placing table 7. A grip 9 is connected to the measuring table 6. A fixed frame 10 is connected to one side of the measuring table 6. A motor 11 is installed on the fixed frame 10. The output shaft of the motor 11 is connected to a threaded rod 12. A sliding block 13 is installed on the threaded rod 12. A threaded sleeve 14 is installed on the sliding block 13. The threaded rod 12 is rotatably connected in the guide groove 8 and has threads with opposite directions at both ends. The threaded sleeve 14 is in threaded cooperation with the threaded rod 12. The sliding block 13 slides in the guide groove 8. Due to the threads with opposite directions at both ends of the threaded rod 12, the two sliding blocks 13 can drive the two fixed plates 15 to move towards each other, so as to tightly clamp the ring. The guide groove 8 can guide and limit the movement of the sliding block 13 to prevent the sliding block 13 from skewing during movement.

[0024] A fixed plate 15 is connected to the sliding block 13. A first roller 16 is installed on the fixed plate 15. Connecting rods 22 are connected to both sides of the fixed plate 15. A side plate 23 is rotatably connected to the connecting rods 22. A second roller 24 is installed on the side plate 23. Torsion springs 25 are connected to both sides of the side plate 23. One end of the torsion spring 25 is connected to the fixed plate 15. By means of the rotatable side plate 23, the second roller 24 can contact the inner diameter of the ferrule with different sizes, thereby improving the applicability of the measuring device.

[0025] A cross bar 17 is slidably connected to the vertical rod 4. A sliding sleeve 18 is slidably connected to the cross bar 17. A fixed clamp 20 is rotatably connected to the sliding sleeve 18. A measuring gauge 19 is installed on the fixed clamp 20. An anti-slip rubber sleeve is sleeved on the handle 9. Tightening bolts 21 are threadedly connected to the cross bar 17, the sliding sleeve 18 and the fixed clamp 20. By loosening the tightening bolts 21, the cross bar 17 and the sliding sleeve 18 slide on the vertical rod 4 and the cross bar 17 respectively, so as to adjust the position of the measuring gauge 19 on the measuring table 6, enabling the measuring gauge 19 to contact the bearing ferrule with different sizes.

[0026] The working principle of the present utility model is as follows:

[0027] Place the bearing ferrule on the placing table 7. By starting the motor 11 to rotate the threaded rod 12, the sliding block 13 moves along the threaded rod 12 through the threaded sleeve 14, prompting the sliding block 13 to drive the two fixed plates 15 to move towards each other, so that the first roller 16 contacts the inner diameter of the ferrule, thereby tightly clamping the bearing ferrule. When contacting, the inner diameter of the ferrule will push the second roller 24 to rotate the side plate 23, prompting the first roller 16 and the second roller 24 to contact the inner diameter of the ferrule, so as to assist the staff to rotate the ferrule through the rotatable first roller 16 and the second roller 24 to measure different positions of the ferrule. The staff loosens the threaded cap 28 to rotate the measuring table 6, so that the fixing bolt 26 slides in the chute 27 and simultaneously pushes the rotating plate 3 to rotate, thereby adjusting the angle of the measuring table 6 for the staff to observe the data.
