[0019] When the ultrasonic wave detects the inside of the roller, the two ends of the roller need to be kept rotating when being clamped to ensure that the ultrasonic wave can detect the inside of the roller in all directions.

[0020] Embodiment 1

[0021] The embodiment of the present application provides a mechanical structure of roller centering adjustment and roller centering clamping and rotating combined, to meet the needs of ultrasonic detection of the roller.

[0022] As Figs. 1-2 The structure of the embodiment of the present application includes:

[0023] The angle inclined plate 1 is formed with a plurality of V-shaped grooves 11 for placing the rollers 101, and the two sides of the opening of the V-shaped groove 11 are provided with clamping assemblies 2 capable of clamping the rollers 101 for rotation.

[0024] The R-axis adjustment module 3 includes a hinge-connected angle adjustment plate a31, an angle adjustment plate b32, and two clamping plates 33 located at both ends of the angle inclined plate 1. The angle inclined plate 1 is swingably arranged between the two clamping plates 33, and the swing direction of the angle inclined plate 1 is perpendicular to the connecting line of the two clamping surfaces of the clamping assembly 2. The angle inclined plate 1 swings with the rollers 101 on the V-shaped groove 11 to make the center axis of the roller 101 parallel to the connecting line of the two clamping surfaces of the clamping assembly 2. The angle adjustment plate a31 is arranged between the two clamping plates 33 and is fixed parallel to the angle inclined plate 1. The angle adjustment plate b32 is movably arranged between the two clamping plates 33, and the moving direction of the angle adjustment plate b32 is consistent with the swing direction of the angle inclined plate 1 between the two clamping plates 33.

[0025] The lifting module 4 includes a lifting plate 41 capable of moving the two clamping plates 33. The moving direction of the lifting plate 41 is perpendicular to the connecting line of the two clamping surfaces of the clamping assembly 2. When the lifting plate 41 moves the two clamping plates 33, the angle inclined plate 1, the angle adjustment plate a31 and the angle adjustment plate b32 move synchronously.

[0026] In the embodiment of the present application, the rollers 101 to be inspected are placed one by one on the V-shaped groove 11, and the relative positions of the center axes of the rollers 101 of different specifications and the angle inclined plate 1 are different when the rollers 101 of different specifications are placed on the V-shaped groove 11. Correspondingly, when the position of the angle inclined plate 1 between the two clamping plates 33 is determined, the relative positions of the center axes of the rollers 101 of different specifications and the connecting line of the two clamping surfaces of the clamping assembly 2 are also different. In order to enable the two clamping surfaces of the clamping assembly 2 to clamp the rollers 101 from both ends of the center axes of the rollers 101, the center axes of the rollers 101 and the connecting line of the two clamping surfaces of the clamping assembly 2 are adjusted to be consistent by adjusting the angle inclined plate 1 between the two clamping plates 33. The specific working principle of the adjustment of the angle inclined plate 1 is as follows:

[0027] 1. The R-axis adjustment module 3 is used to adjust the swing angle of the angle inclined plate 1 between the two clamping plates 33, so as to adjust the center axes of the rollers 101 on the V-shaped groove 11 to be parallel to the connecting line of the two clamping surfaces of the clamping assembly 2. An external power moves the angle adjustment plate b32, the moving direction of the angle adjustment plate b32 corresponds to the swing direction of the angle inclined plate 1 between the two clamping plates 33, the angle adjustment plate b32 drives the hinge connection point of the angle adjustment plate a31 and the angle adjustment plate b32 to move synchronously in the same direction, the angle adjustment plate a31 drives the angle inclined plate 1 to swing between the two clamping plates 33 by a small amplitude, the swing direction of the angle inclined plate 1 between the two clamping plates 33 is perpendicular to the connecting line of the two clamping surfaces of the clamping assembly 2, and the swing of the angle inclined plate 1 adjusts the extension directions of both ends of the center axes of the rollers 101, so that the center axes of the rollers 101 are parallel to the connecting line of the two clamping surfaces of the clamping assembly 2.

[0028] 2. By adjusting the relative position of the connecting line between the angle tilting plate 1 and the two clamping surfaces of the clamping assembly 2 through the lifting assembly 4, the extension positions at both ends of the central axis of the roller 101 are respectively facing the two clamping surfaces of the clamping assembly 2. This allows the two clamping surfaces of the clamping assembly 2 to clamp the roller 101 from both ends of the central axis of the roller 101. After the central axis of the roller 101 is parallel to the connecting line between the two clamping surfaces of the clamping assembly 2, external power is provided to move the lifting plate 41. The moving direction of the lifting plate 41 is perpendicular to the connecting line between the two clamping surfaces of the clamping assembly 2, thereby driving the angle tilting plate 1, the angle adjustment plate a31, and the angle... The angle adjustment plate b32 moves synchronously, and the synchronous movement of the angle adjustment plate a31 and the angle adjustment plate b32 ensures that the extension direction of both ends of the central axis of the roller 101 remains unchanged, thereby ensuring that the central axis of the roller 101 is always parallel to the connection line of the two clamping surfaces of the clamping assembly 2. The movement of the angle tilting plate 1 adjusts the relative position of the central axis of the roller 101 and the connection line of the two clamping surfaces of the clamping assembly 2, so that the central axis of the roller 101 and the connection line of the two clamping surfaces of the clamping assembly 2 coincide with each other, thereby realizing that the two ends of the central axis of the roller 101 are respectively facing the two clamping surfaces of the clamping assembly 2.

[0029] In this embodiment of the invention, the above steps ensure that the two ends of the central axis of the roller 101 on the V-groove 11 are respectively aligned with the two clamping surfaces of the clamping assembly 2. At this time, the two clamping surfaces of the clamping assembly 2 clamp the two ends of the central axis of the roller 101, thereby centering and clamping the roller 101 on the clamping assembly 2. Before subsequent ultrasonic testing of the roller 101 on the clamping assembly 2, the lifting plate 41 continues to move the angle tilting plate 1, the angle adjusting plate a31, and the angle adjusting plate b32. On the one hand, the movement of the angle tilting plate 1 separates the roller 101 from the V-groove 11, making it easier for the clamping assembly 2 to clamp the roller. Roller 101 rotates while external ultrasonic waves inspect the rotating roller for flaws. Meanwhile, angle adjustment plates a31 and b32 move synchronously, ensuring that the angle tilting plate 1 maintains its adjusted swing position between the two clamping plates 33. This ensures that when rollers 101 of the same specification are subsequently placed on the angle tilting plate 1, the central axis of roller 101 remains parallel to the connection line between the two clamping surfaces of the clamping assembly 2. Therefore, when centering and clamping rollers 101 of the same specification, there is no need to repeatedly adjust the position of the central axis of roller 101, thus improving the efficiency of centering and clamping flaw inspection of roller 101.

[0030] In the embodiment of the present application, in order to specifically illustrate the specific structure of the clamping assembly 2, the clamping assembly 2 includes a clamping shaft 21 and a driving end rotating shaft 22, the lifting plate 41 is provided with an avoiding groove 411, one end of the clamping shaft 21 is movably arranged at one end of the opening of the V-shaped groove 11, the other end of the clamping shaft 21 penetrates through the avoiding groove 411 and extends outside the lifting plate 41, the driving end rotating shaft 22 is rotatably arranged at the other end of the opening of the V-shaped groove 11, the moving direction of the clamping shaft 21 is towards the driving end rotating shaft 22, and the end of the clamping shaft 21 is provided with a free rotating driven end rotating shaft 211, the driven end rotating shaft 211 and the driving end rotating shaft 22 are oppositely arranged at the two sides of the angle inclined plate 1.

[0031] In the embodiment of the present application, when the clamping assembly 2 needs to clamp the roller 101 on the V-shaped groove 11, the external power drives the clamping shaft 21 to move towards the driving end rotating shaft 22, so that the two ends of the roller 101 are clamped between the clamping shaft 21 and the driving end rotating shaft 22, and when the clamping assembly 2 needs to rotate the roller 101 clamped between the clamping shaft 21 and the driving end rotating shaft 22, the external power drives the driving end rotating shaft 22 to rotate, and the rotation drives the roller 101 to rotate between the driving end rotating shaft 22 and the driven end rotating shaft 211, and at this time, the two clamping surfaces of the clamping assembly 2 for the roller 101 are the driving end rotating shaft 22 and the driven end rotating shaft 211, that is, the angle inclined plate 1 drives the roller on the V-shaped groove 11 to swing in a small amplitude, so that the central axis of the roller 101 is parallel to the connecting line of the driven end rotating shaft 211 and the driving end rotating shaft 22.

[0032] In the embodiment of the present application, the design of the avoiding groove 411 facilitates the movement of the clamping shaft 21 when it penetrates through the avoiding groove 411, and the clamping shaft 21 extends outside the lifting plate 41 through the avoiding groove 411, so that the external power driving the clamping shaft 21 to move can be installed outside the lifting plate 41, thereby ensuring the rationality of the overall structure of the embodiment of the present application.

[0033] In the embodiment of the present application, the driving end rotating shaft 22 is sleeved with a polyurethane non-slip pad 221, which avoids the phenomenon of slipping between the driving end rotating shaft 22 and the end of the roller 101, thereby ensuring the stability of the rotation of the roller 101 driven by the driving end rotating shaft 22.

[0035] In the embodiment of the present application, since the moving directions of the angle adjusting plate b32 and the lifting plate 41 are both perpendicular to the connecting line of the two clamping surfaces of the clamping assembly 2, the moving directions of the angle adjusting plate b32 and the lifting plate 41 are parallel to each other, the setting of the sliding groove 5 facilitates the movement of the angle adjusting plate b32 inside the sliding groove 5, and the setting of the cover plate 6 ensures that the angle adjusting plate b32 always moves inside the sliding groove 5, thereby ensuring the stability of the movement of the angle adjusting plate b32.

[0037] In the embodiment of the present application, the setting of the two rotating shafts 102 enables the angle tilting plate to freely swing between the two clamping plates 33, the symmetric setting of the two clamping surfaces of the clamping assembly 2 on the left and right sides of the angle tilting plate 1 enables the connecting line of the two clamping surfaces of the clamping assembly 2 to be parallel to the horizontal plane, the connecting plate 12 is arranged at the center position of the left side of the angle tilting plate 1, and the connecting line of the two rotating shafts 102 is close to the left side of the angle tilting plate 1, and the above setting determines the swinging direction of the angle tilting plate 1 between the two clamping plates 33, specifically, the swinging direction of the angle tilting plate 1 between the two clamping plates 33 is upward and downward swinging, and the moving direction of the angle adjusting plate b32 is upward and downward movement.
