[0022] Since the existing ultrasonic nondestructive testing device can only detect the outer ring of a bearing at a specific angle and cannot obtain multiple groups of data simultaneously, which greatly affects the detection efficiency; therefore, the inventor of the present application provides a bearing outer ring wear detection device for the above problems, which can adjust the angle, detect different parts of the bearing outer ring, and realize the simultaneous acquisition of multiple groups of data.

[0023] As Figures 1-6 shown, a bearing outer ring wear detection device includes: a main frame body 1, a bearing end cover 2, an angle adjuster 3, a bolt-integrated ultrasonic probe 4 and a jaw 5; an angle fixing hole 7 is provided on one side of the main frame body 1; the bearing end cover 2 is provided at one end of the main frame body 1; the angle adjuster 3 is provided outside the main frame body 1; the bolt-integrated ultrasonic probe 4 is connected to the angle adjuster 3 and the main frame body 1; the jaw 5 is provided inside the main frame body 1 and is connected to the bolt-integrated ultrasonic probe 4.

[0024] In this embodiment, as Figure 1 , Figure 3 shown, one end of the main frame body 1 is provided with a threaded hole 8, and the bearing end cover 2 is connected to the main frame body 1 through the threaded hole 8; one end of the main frame body 1 away from the threaded hole 8 is provided with a slide rail 16, and the angle adjuster 3 is connected to the main frame body 1 through the slide rail 16; a plurality of sliding grooves 6 are penetrated through one side of the main frame body 1, and the sliding grooves 6 are adapted to the bolt-integrated ultrasonic probe 4, and the bolt-integrated ultrasonic probe 4 moves through the sliding grooves 6; a base 13 is provided below the main frame body 1, and fixing holes 9 are penetrated through both ends of the base 13.

[0025] Among them, the angle fixing holes 7 and the sliding grooves 6 are uniformly arranged, and the proportion of the angle fixing holes 7 in the cross section of the main frame body 1 is 70 degrees.

[0026] Based on the above embodiment, the number of the angle fixing holes 7 depends on the aperture size opened and determines the number of adjustable angles; the bolt-integrated ultrasonic probe 4 moves through the sliding grooves 6 and is fixed through the angle fixing holes 7, so as to detect different parts of the outer ring of the bearing.

[0027] In this embodiment, as Figure 4 shown, a through hole is provided in the middle of the angle adjuster 3; four legs 14 are provided on the periphery of the angle adjuster 3, and the legs 14 are uniformly arranged. A slider 10 is connected to the end of each leg 14, and a connection hole 11 is penetrated through each leg. The connection hole 11 is adapted to the bolt-integrated ultrasonic probe 4, and the bolt-integrated ultrasonic probe 4 is connected to the angle adjuster 3 through the connection hole 11.

[0028] Among them, the angle adjuster 3 rotates through the slider 10 and the slide rail 16 of the main frame body 1.

[0029] In this embodiment, the legs 14 are all of double-layer structure, and when the angle adjuster 3 is installed on the outside of the main frame body 1, the positions of the connection holes 11 correspond to the angle fixing holes 7 and the sliding grooves 6 on the main frame body 1.

[0030] Based on the above embodiment, the double-layer structure of the legs 14 can better play a role in orienting the bolt-integrated ultrasonic probe 4.

[0031] In this embodiment, as Figure 2 , Figure 5 , Figure 6 shown, a positioning hole 15 is penetrated through the top of the claw 5, and a rectangular groove is opened at the bottom of the claw 5, and a baffle 12 is arranged in the rectangular groove.

[0032] Based on the above embodiment, the bolt-integrated ultrasonic probe 4 and the claw 5 perform radial positioning on the bearing, and the claw 5 and the baffle 12 are used for the radial positioning of the bolt-integrated ultrasonic probe 4.

[0033] In this embodiment, the method for detecting the wear of the outer ring of the bearing mainly includes the following steps:

[0034] S1. Align the bolt-integrated ultrasonic probe 4 with the surface of the outer ring of the bearing to be measured;

[0035] S2. Transmit ultrasonic waves. The incident wave enters from the outer surface of the outer ring of the bearing, is reflected by the inner surface of the bearing, and the reflected wave is received by the ultrasonic probe again;

[0036] S3. Record the time t required for the ultrasonic wave to travel back and forth in the outer ring of the bearing. Given the sound velocity v, the thickness H can be calculated by the formula H = vt / 2. If wear occurs, the propagation time t of the ultrasonic wave decreases, and the measured thickness H also decreases accordingly, indicating that wear has occurred on the outer ring of the bearing.

[0037] Based on the above embodiment, when the present invention is in use, the bearing is placed inside the main frame body 1, and then the bearing end cover 2 is bolted to the threaded hole 8 to axially fix the bearing; the angle adjuster 3 is installed on the outside of the main frame body 1, and the positions of the four legs 14 correspond to the positions of the angle fixing holes 7 and the sliding grooves 6; the four bolt-integrated ultrasonic probes 4 respectively extend into the main frame body 1 through the connection holes 11 and the angle fixing holes 7 and the sliding grooves 6. The angle adjuster 3 rotates on the outside of the main frame body through the bolt-integrated ultrasonic probe 4, the sliding grooves 6 and the sliding rails 16. The bolt-integrated ultrasonic probes 4 are respectively connected with claws 5, and the claws 5 are all placed on the outer ring of the bearing to radially fix the bearing; since there are multiple angle fixing holes 7, when it is necessary to rotate the angle to obtain multiple sets of wear data of the outer ring of the bearing, the bolt-integrated ultrasonic probe 4 in the angle fixing hole 7 can be removed, the angle adjuster 3 is rotated, and when the connection hole 11 is aligned with the angle fixing hole 7, the bolt-integrated ultrasonic probe 4 is reinstalled, so that the angle can be adjusted to detect different parts of the outer ring of the bearing and realize the simultaneous acquisition of multiple sets of data.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
