[0002] An aligning roller bearing has double-row rollers, with 1 common spherical raceway on the outer ring and 2 raceways on the inner ring which are inclined at an angle relative to the bearing axis. When using the bearing, in order to ensure the correct parameters and perfect surface performance of the bearing at the time of leaving the factory, various parameter detections of the bearing are usually carried out before leaving the factory.

[0003] When detecting the outer diameter size of an aligning roller bearing, the bearing is placed on the detection table surface, so that three sides of the bearing are positioned by two positioning blocks and a detection needle. Subsequently, the inner ring of the bearing is controlled by hand, and the outer ring of the bearing is pushed to rotate to adjust the angle for detecting the outer diameter size of the bearing.

[0004] However, during the detection process, it is rather inconvenient to push the outer ring of the bearing to rotate by manually pressing the inner ring of the bearing, and the inner ring may be slightly deflected due to uneven force when the outer ring of the bearing is pushed to rotate, resulting in errors in the detection results and affecting the detection accuracy.

DETAILED DESCRIPTION

[0026] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0027] like Figures 1-3As shown in the figure, the utility model provides a technical solution: a centering roller bearing detection device for facilitating the adjustment of the angle of a workpiece, including a base 1. An electric sliding seat 4 is slidably arranged on one side of the base 1. A first positioning rod 5 is threadedly connected to the inner wall of the electric sliding seat 4. A pressure gauge 7 is arranged on one side of the top end of the base 1. A detection needle 8 is arranged on one side of the pressure gauge 7. A second positioning rod 6 is arranged on one side of the bottom end of the base 1. A positioning device 2 is arranged on the outer surface of the base 1. The positioning device 2 includes a slider 22. A slide bar 23 is fixedly connected to one side of the slider 22. A threaded ring 24 is threadedly connected to the outer surface of the slide bar 23. The outer surface of the slide bar 23 slides inside the inner wall of the base 1. A chute 21 is formed on the outer surface of the base 1. The bottom end of the slider 22 slides inside the inner wall of the chute 21. A threaded cylinder 25 is rotatably connected to one side of the slider 22. Two screw rods 26 are threadedly connected to the inner wall of the threaded cylinder 25. The threaded directions of the outer surfaces of the two screw rods 26 are opposite. One end of the screw rod 26 away from the threaded cylinder 25 is fixedly connected to a top block 27. A round rod 28 is fixedly connected to one side of the top block 27. The outer surface of the round rod 28 slides inside the inner wall of the slider 22. By setting the top block 27, when detecting the outer diameter of the bearing, first place the bearing on the top of the outer surface of the base 1 below the detection needle 8. Control the electric sliding seat 4 to move and adjust the position through the control button on one side of the base 1. Then rotate the first positioning rod 5 to move and adjust the position so that one end contacts one side of the outer ring of the bearing. Operate the electric push rod at the bottom end of the base 1 to push the second positioning rod 6 to move and make one end contact one side of the outer ring of the bearing. Then rotate the threaded cylinder 25 to make the two screw rods 26 move in opposite directions inside the inner wall of the threaded cylinder 25. The round rod 28 on one side of the top block 27 will slide inside the inner wall of the slider 22 to press one side of the top block 27 against the inner wall of the inner ring of the bearing. At the same time, push the slider 22 to slide inside the inner wall of the chute 21 to adjust the position of the slider 22 so that the two top blocks 27 can move the maximum distance to press against the inner wall of the inner ring of the bearing to fix the position of the inner ring of the bearing on the outer surface of the base 1. Then rotate the threaded ring 24 to make the threaded ring 24 move on the outer surface of the slide bar 23 and press one side against one side of the base 1 to fix the position of the slider 22. By setting the positioning device 2, when detecting the outer diameter of the bearing, the bearing can be placed on one side of the base 1. Adjust the positions of the two top blocks 27 by rotating the threaded cylinder 25 to press one side of the two top blocks 27 against both sides of the inner wall of the inner ring of the bearing to fix the position of the inner ring of the bearing. Then the staff can fix the position of the inner ring of the bearing without using their hands, and can conveniently push the outer ring of the bearing to rotate and adjust the angle to detect the outer diameter of the bearing, improving the convenience when using the detection device.

[0028] Specifically, as Figure 2 and Figure 3As shown, the outer surface of the threaded barrel 25 is fixedly connected with a plurality of convex strips 29, and the convex strips 29 are distributed in a circle on the outer surface of the threaded barrel 25. By pressing the convex strips 29 on the outer surface of the threaded barrel 25 with your hand, you can more conveniently push the threaded barrel 25 to rotate and control the screw 26 to move and adjust the position of the top block 27. One side of the threaded ring 24 is fixedly connected with a gasket 210, and the gasket 210 is made of rubber material. When the side of the threaded ring 24 provided with the rubber gasket 210 is pressed tightly against the outer surface of the base 1 to fix the position of the slide rod 23, it is more stable and less likely to slide accidentally.

[0029] Specifically, Figure 2 and Figure 3 As shown, one end of the slide bar 23 away from the slider 22 is fixedly connected to a U-shaped rod 211, and both ends of the U-shaped rod 211 slide on one side of the base 1. When the slider and the slide bar 23 move, the two ends of the U-shaped rod 211 will slide on one side of the base 1, further limiting the angle between the slide bar 23 and the base, and the slider 22 and the slide groove 21, thereby avoiding the angle of the slider 22 and the slide bar 23 from being deflected as much as possible.

[0030] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an anti-skid device 3 is provided at the bottom end of the base 1, and the anti-skid device 3 includes a bottom plate 32, and L-shaped rubber rods 33 are fixedly connected to the two sides of the top of the bottom plate 32, and a plurality of suction cups 34 are fixedly connected to the bottom end of the bottom plate 32. Slots 31 are provided on both sides of the base 1. When using the detection device, the two rubber rods 33 at the top of the bottom plate 32 can be pried outward, and then the top of the bottom plate 32 is attached to the bottom end of the base 1, and the rubber rods 33 are loosened so that the top of the rubber rods 33 are inserted into the two slots 31 on the outer surface of the base 1, and the bottom plate 32 is fixed to the bottom end of the base 1. The suction cups 34 at the bottom end of the bottom plate 32 can be used to adsorb the bottom plate 32 and the base 1 as a whole on the placement surface, so as to avoid accidental sliding of the base 1 as a whole when using the detection device as much as possible, thereby improving the stability of the detection device when using it.

[0031] Specifically, Figure 2 , Figure 4 and Figure 5 As shown, a groove block 35 is fixedly connected to one side of the rubber rod 33, and grooves are respectively provided on the upper and lower sides of the groove block 35. Pinching the grooves on the upper and lower sides of the groove block 35 can more conveniently pull the rubber rod 33 to bend outward and deform. The bottom end of the bottom plate 32 is fixedly connected to an anti-slip strip 36, and the anti-slip strip 36 is made of rubber material. When the suction cup 34 at the bottom end of the bottom plate 32 is adsorbed on the placement surface, the rubber anti-slip strip 36 at the bottom end of the bottom plate 32 will contact the placement surface, thereby increasing the friction when the bottom end of the bottom plate 32 contacts the placement surface, and further improving the anti-slip effect of the anti-slip device 3.

[0032] The working principle of the present utility model is as follows:

[0033] S1. When using the detection device to detect the outer diameter of the spherical roller bearing, first pinch the grooves on the upper and lower sides of the groove block 35 and pull the rubber rod 33 to make the rubber rod 33 bend outward and deform. Fit the top end of the bottom plate 32 against the bottom end of the base 1. Release the rubber rod 33 so that the top end of the rubber rod 33 snaps into the two slots 31 on the outer surface of the base 1, fixing the bottom plate 32 to the bottom end of the base 1. The bottom plate 32 and the base 1 as a whole can be adsorbed on the placement surface through the suction cups 34 at the bottom end of the bottom plate 32. Then place the bearing on the top of the outer surface of the base 1 below the detection needle 8. Control the electric slide 4 to move and adjust the position through the control button on one side of the base 1. Then rotate the first positioning rod 5 to move and adjust the position so that one end contacts one side of the outer ring of the bearing. Operate the electric push rod at the bottom end of the base 1 to push the second positioning rod 6 to move and make one end contact one side of the outer ring of the bearing. Then rotate the threaded cylinder 25 to make the two screw rods 26 move in opposite directions on the inner wall of the threaded cylinder 25. The round rod 28 on one side of the top block 27 will slide on the inner wall of the slider 22 and press one side of the top block 27 against the inner wall of the inner ring of the bearing. At the same time, push the slider 22 to slide on the inner wall of the chute 21 to adjust the position of the slider 22 so that the two top blocks 27 can move the maximum distance to press against the inner wall of the inner ring of the bearing to fix the position of the inner ring of the bearing on the outer surface of the base 1. Finally, rotate the threaded ring 24 to move the threaded ring 24 on the outer surface of the slide rod 23 and press one side tightly against one side of the base 1 to fix the position of the slider 22.

[0034] S2. Push the outer ring of the bearing to rotate. When the outer ring rotates, it contacts one end of the detection needle 8. If the pressure received by one end of the detection needle 8 changes and is displayed on the pressure gauge 7, it means that there are defects in the outer diameter of the bearing outer ring and the size is deviated, then the bearing detection is unqualified. If the index of the pressure gauge 7 does not change, the bearing detection is qualified. After the detection is completed, take out the bearing, push the threaded cylinder 25 to rotate to retract the two screw rods 26 into the threaded cylinder 25 to control the two top blocks 27 to approach each other, which is convenient for fixing the next bearing to be detected.

[0035] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0036] The above describes in detail the preferred embodiments of this patent. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of this patent.
