[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, reference Figures 1 to 5 , is the first embodiment of the present invention, which provides a bearing surface scanning device, which can achieve the effect of scanning the outer arc surface and the inner arc surface of the bearing with one clamping and positioning, and includes a bearing surface scanning device, including, a positioning member 100, the positioning member 100 can clamp and position the bearing to be scanned, and at the same time drive the bearing to rotate when scanning the bearing, so that the scanning device can scan the entire arc surface, ensuring that the scanning is complete and continuous, the positioning member 100 includes a base 101, a flip rod 102 arranged on the top of the base 101 and a clamping structure 103 arranged on the top of the flip rod 102, the flip rod 102 is rotatably connected to the base 101, the clamping member clamps the bearing, and drives the bearing to rotate when scanning the bearing, when the inner arc surface of the bearing is scanned, the flip rod 102 can be used to drive the clamping structure 103 and the bearing to flip together, change the surface of the bearing close to the scanning device, so that it can scan the outer arc surface of the bearing; and,

[0029] The scanning component 200 is arranged on the side of the bearing to be scanned, and performs scanning and flaw detection on the curved surface of the bearing.

[0030] Specifically, the bearing is first clamped on the clamping structure 103. At this time, the scanning device on the scanning component 200 of the bearing is in the inner ring of the bearing. When the scanning device scans the inner arc surface of the bearing, the clamping component will drive the bearing to rotate, so that the scanning device can scan the entire arc surface, ensuring that the scanning is complete and continuous. After the entire inner arc surface is scanned, the flip rod 102 is used to drive the clamping structure 103 and the bearing to flip together. After flipping, the scanning device is outside the bearing, and it can scan the outer arc surface of the bearing. Only one clamping and positioning is required to scan the outer and inner arc surfaces of the bearing.

[0031] Example 2, reference Figures 1 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, the clamping structure 103 includes a fixed roller mechanism 103a arranged on the top of the flip rod 102, the fixed roller mechanism 103a is fixedly connected to the flip rod 102, and a movable roller mechanism 103b is arranged on the side of the fixed roller mechanism 103a.

[0032] Furthermore, the fixed roller mechanism 103a includes a rotating frame 103a-1, the bottom of which is fixedly connected to the flip rod 102. When the flip rod 102 is rotated, the rotating frame 103a-1 will be driven to rotate together. A motor 103a-2 is arranged on the side of the rotating frame 103a-1, and an active clamping roller 103a-3 is arranged at the output end of the motor 103a-2. The outer wall of the active clamping roller 103a-3 is rotatably connected to the rotating frame 103a-1, and it can rotate on the rotating frame 103a-1.

[0033] Furthermore, the movable roller mechanism 103b includes a U-shaped slide 103b-1 disposed on the side of the rotating frame 103a-1, the U-shaped slide 103b-1 can slide on the side of the rotating frame 103a-1, a driven clamping roller 103b-2 is disposed on the side of the U-shaped slide 103b-1, the outer wall of the driven clamping roller 103b-2 is rotatably connected to the U-shaped slide 103b-1, the driven clamping roller 103b-2 can rotate on the U-shaped slide 103b-1, and a first connecting rod 103b-3 is disposed on the top of the U-shaped slide 103b-1, and the bottom of the first connecting rod 103b-3 is connected to the U-shaped slide 103b-1. The top is rotatably connected, a support rod 103b-4 is arranged on the top of the first connecting rod 103b-3, the outer wall of the support rod 103b-4 is rotatably connected to the first connecting rod 103b-3, a second connecting rod 103b-5 is arranged on the outer wall of the support rod 103b-4, the bottom of the second connecting rod 103b-5 is connected to the rotating frame 103a-1, the bottom of the second connecting rod 103b-5 is rotatably connected to the rotating frame 103a-1, the top of the second supporting rod 103b-4 is rotatably connected to the supporting rod 103b-4, the first connecting rod 103b-3 and the second connecting rod 103b-5 jointly provide support for the supporting rod 103b-4.

[0034] Further, such as Figure 4As shown, the bottom connection of the first connecting rod 103b-3 and the central axis of the driven clamping roller 103b-2 are in the same vertical plane, the bottom connection of the second connecting rod 103b-5 and the central axis of the active clamping roller 103a-3 are in the same vertical plane, the side of the support rod 103b-4 is provided with a top frame 103b-6, the inner wall of the top frame 103b-6 is provided with a top rod 103b-7, the bottom of the top rod 103b-7 is provided with a pressure roller 103b-8, and the outer wall of the top rod 103b-7 is provided with a locking ring 103b-9 After placing the bearing to be scanned on the active clamping roller 103a-3 and the driven clamping roller 103b-2, the push rod 103b-7 can be pressed down to allow the bottom of the pressure roller 103b-8 to contact the inner arc surface of the bearing, and the locking ring 103b-9 can be rotated to make the pressure roller 103b-8 press the bearing to complete the clamping and positioning. The rotation of the motor 103a-2 can drive the active clamping roller 103a-3 to rotate, and the active clamping roller 103a-3 drives the bearing to rotate, so that the scanning device can continuously and completely scan the entire inner arc surface of the bearing in the bearing.

[0035] During work, it is necessary to scan different types of bearings, and the clamping size of the entire clamping structure 103 needs to be adjusted. Sliding the U-shaped slide 103b-1 in the direction away from the motor 103a-2 will drive the driven clamping roller 103b-2 away from the active clamping roller 103a-3, which can hold a larger bearing, thereby increasing the clamping size. At the same time, the sliding of the driven clamping roller 103b-2 will drive the first connecting rod 103b-3 to slide together. Since the bottom connection of the first connecting rod 103b-3 and the central axis of the driven clamping roller 103b-2 are in the same vertical plane, and the bottom connection of the second connecting rod 103b-5 and the central axis of the active clamping roller 103a-3 are in the same vertical plane, the first connecting rod 103b-3 and the second connecting rod 103b-5 have the same size, so The connecting line between the first connecting rod 103b-3 and the second connecting rod 103b-5 and the driven clamping roller 103b-2 to the active clamping roller 103a-3 is always an isosceles triangle. The support rod 103b-4 is jointly supported by the first connecting rod 103b-3 and the second connecting rod 103b-5, so the support rod 103b-4 is always located at the vertex of the isosceles triangle and the midpoint of the connecting line between the driven clamping roller 103b-2 and the active clamping roller 103a-3. Therefore, the pressure roller 103b-8 at the bottom of the support rod 103b-4 can always press against the lowest point of the inner arc surface of the bearing shell, making it convenient to adjust the clamping size. You only need to slide the U-shaped slide 103b-1. When the U-shaped slide 103b-1 is slid toward the direction of the motor 103a-2, the clamping size can be reduced.

[0036] Specifically, when scanning the inside of the bearing, after placing the bearing to be scanned on the active clamping roller 103a-3 and the driven clamping roller 103b-2, the push rod 103b-7 can be pressed to allow the bottom of the pressure roller 103b-8 to contact the inner arc surface of the bearing, and the locking ring 103b-9 can be rotated to make the pressure roller 103b-8 press the bearing to complete the clamping and positioning. The rotation of the motor 103a-2 can drive the active clamping roller 103a-3 to rotate, and the active clamping roller 103a-3 drives the bearing to rotate, so that the scanning device can continuously and completely scan the entire inner arc surface of the bearing in the bearing. When the scanning of the inner arc surface is completed, the flip rod 102 is rotated 180° to drive the bearing to flip so that it can scan the outer arc surface. Figure 5 As shown, when the clamping size needs to be adjusted, it is only necessary to slide the U-shaped slide 103b-1.

[0037] Example 3, reference Figures 1 to 5 , which is the third embodiment of the present invention. Different from the previous embodiment, the scanning component 200 includes a scanning frame 201 arranged on the top of the base 101, and a scanner 202 is arranged on the top of the scanning frame 201. The scanner 202 has a long strip scanning probe to scan and detect the surface of the bearing shell. A slide groove 203 is opened at the bottom of the scanning frame 201. The bottom of the scanning frame 201 is connected to the slide groove 203. The scanning frame 201 can slide on the base 101. The slide groove 203 is opened and connected to the top of the base 101. A threaded rod 204 is arranged on the side of the scanning frame 201. The outer wall of the threaded rod 204 A positioning block 205 is provided, the bottom of the positioning block 205 is connected to the base 101, the outer surface of the threaded rod 204 is threadedly connected to the inner wall of the positioning block 205, and the end of the threaded rod 204 is rotatably connected to the scanning frame 201. When the flip rod 102 is rotated to drive the bearing to flip, sometimes the bearing will interfere with the scanning probe due to its large size. It only needs to rotate the threaded rod 204. Under the action of the positioning block 205, the threaded rod 204 can drive the scanning frame 201 to slide in a direction away from the clamping structure 103, so that it is away from the clamping structure 103, so that the clamping structure 103 can rotate smoothly.

[0038] This embodiment also provides a scanning method, which includes the above-mentioned bearing surface scanning device, and further includes:

[0039] Place the bearing to be scanned on the active clamping roller 103a-3 and the driven clamping roller 103b-2, press the push rod 103b-7 to make the pressure roller 103b-8 press the bearing to complete the clamping and positioning;

[0040] The scanner 202 is started to scan, and the motor 103a-2 rotates to drive the bearing to rotate and scan the entire inner arc surface;

[0041] The flip rod 102 is rotated to scan the outer arc surface of the bearing bush.

[0042] Specifically, when the bearing is large in size, rotating the flip rod 102 to cause the bearing to flip and interfere with the scanning probe, the threaded rod 204 can be rotated. Under the action of the positioning block 205, the threaded rod 204 can drive the scanning frame 201 to slide in a direction away from the clamping structure 103, so that it is away from the clamping structure 103.
