[0002] Radiographic testing is a common method in nondestructive testing technology. It uses X-rays or gamma rays to irradiate the test piece and uses the principle of radiation penetration and absorption to obtain the structural information inside the component. Radiographic testing can detect defects such as cracks, pores, inclusions, etc. inside the component, and has high sensitivity and reliability. Radiographic testing has been widely used in the aerospace field. When using radiographic testing of aviation components, a radioactive source is usually used to test the test piece. In order to ensure the accuracy of the test, it is necessary to perform multi-angle radiographic testing on the test piece.

DETAILED DESCRIPTION

[0019] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0020] Reference Figure 1-Figure 10 The present embodiment provides a radiation detection displacement assembly, including a mounting frame 11, a first rotational motion part 12 and a second rotational motion part 13; the mounting frame 11 is provided with a plurality of parts which are detachably connected to the detected part 4 respectively; the first rotational motion part 12 includes a first rotation element detachably connected to the mounting frame 11, and based on the rotation of the first rotation element, the mounting frame 11 rotates around a first axis, and the first axis is parallel to the length direction of the detected part 4; the second rotational motion part 13 includes a second rotation element rotatably connected to the first rotational motion part 12, and based on the rotation of the second rotation element, the first rotational motion part 12 rotates around a second axis, which is used to adjust the pitch angle of the mounting frame 11, and the first axis is perpendicular to the second axis.

[0021] When the present embodiment is working, the part to be detected 4 is mounted on the mounting frame 11; during the process of X-ray detection, the first rotating motion part 12 drives the mounting frame 11 to rotate around the first axis through the first rotating element. Since the first axis is parallel to the length direction of the part to be detected 4, different rotational postures of the part to be detected 4 are obtained; the second rotating motion part 13 drives the first rotating motion part 12 and the mounting frame 11 to rotate around the second axis through the second rotating element, which is used to adjust the pitch angle of the mounting frame 11, thereby obtaining the posture of the part to be detected 4 at different pitch angles; the present invention adjusts the rotational posture of the part to be detected 4 through the first rotating motion part 12, and adjusts the pitch angle of the part to be detected 4 through the second rotating motion part 13, so as to realize the displacement of the part to be detected 4; and since the part to be detected 4 and the mounting frame 11 are detachably connected, the stability of the part to be detected 4 when rotating around the first axis and the second axis is guaranteed, and the rotation angle of the part to be detected 4 before and after rotation is ensured to be controllable, so as to realize multi-angle X-ray detection of the part to be detected 4.

[0022] In this embodiment, the detachable connection between the mounting frame 11 and the to-be-detected component 4 can be achieved in a variety of ways, such as: snap-on, plug-in, extrusion, gluing, etc.

[0023] When the mounting frame 11 and the part to be detected 4 are detachably connected by means of a snap connection, a mounting groove 111 is provided on one side of the mounting frame 11 close to the part to be detected 4, and the part to be detected 4 is snapped into the mounting groove 111, and the part to be detected 4 is supported by the bottom and / or side wall of the mounting groove 111, and the friction between the two is increased, thereby realizing the detachable connection between the mounting frame 11 and the part to be detected 4. Preferably, an elastic plate is fixedly provided on the bottom and / or side wall of the mounting groove 111, and the part to be detected 4 is elastically supported and protected by the elastic plate. The elastic plate can have the characteristics of flexibility and low density while being elastic, so as to further protect the part to be detected 4 and reduce the influence of the elastic plate on the radiation detection.

[0024] Of course, the mounting frame 11 can also be a plate, but compared with the mounting groove 111, since there is no support from the bottom and / or side walls of the mounting groove 111, the member to be detected 4 can only be supported by the friction between the plate and the member to be detected 4. At this time, the rotation angle of the member to be detected 4 around the first axis and the pitch angle around the second axis will be affected. At this time, only some small-angle X-ray detection can be performed.

[0025] In order to ensure that the detected object 4 can stably perform large-angle radiographic detection, preferably, a clamping assembly is connected to the side of the mounting frame 11 close to the detected object 4, and the clamping assembly includes a fixing element for fixing the detected object 4. The detected object 4 is fixed by the fixing element in the clamping assembly to prevent the detected object 4 from being separated from the mounting frame 11 or falling and bumping due to the reduction of friction between the mounting frame 11 and the detected object 4 during large-angle radiographic detection; the stability of the detected object 4 when rotating around the first axis and the second axis is further ensured by the clamping assembly.

[0026] The clamping assembly can adopt a strapping tape or an extrusion fixing structure; when the clamping assembly adopts a strapping tape, the material of the strapping tape is preferably a flexible low-density material to reduce the influence of the strapping tape on the part to be detected 4. In the present embodiment, the clamping assembly adopts an extrusion fixing structure, the clamping assembly includes a fixed rod 112, the fixed element is a rotating rod 113, the fixed rod 112 and the rotating rod 113 are rotatably connected, and an elastic extrusion head 114 is provided at one end of the rotating rod 113 away from the fixed rod 112. Based on the rotation of the rotating rod 113, the elastic extrusion head 114 is controlled to apply an extrusion force to the part to be detected 4. While supporting the part to be detected 4 through the elastic extrusion head 114, the friction between the part to be detected 4 and the mounting frame 11 is increased, the stability of the connection between the part to be detected 4 and the mounting frame 11 is improved, and the stability of the part to be detected 4 when rotating around the first axis and the second axis is further ensured. In some embodiments, a lead type mark can also be detachably connected between the mounting frame 11 and the clamping assembly to distinguish and identify the part to be detected. Of course, the clamping assembly can also use an elastic clip, the size of the elastic clip is slightly larger than the size of the mounting groove 111, and the elastic clip and the mounting groove 111 are snapped together by interference fit. At the same time, the elastic clip and the part to be detected 4 are in contact with each other to prevent the part to be detected 4 from shaking between the elastic clip and the mounting groove 111.

[0027] Preferably, the first rotating motion part 12 of this embodiment adopts shaft rotation; the first rotating element is the first rotating shaft 121, the first rotating shaft 121 is detachably connected to the mounting frame 11, the first rotating shaft 121 is rotatably connected to the second rotating element, and the first rotating shaft 121 is driven to rotate by the first driving component. The first rotating shaft 121 is driven to rotate by the first driving component, and the first rotating shaft 121 drives the mounting frame 11 to rotate around the first axis. At this time, the first axis is the axis of the first rotating shaft 121. The shaft rotation adopted in this embodiment can achieve 360-degree continuous rotation.

[0028] The first drive assembly can be driven by a belt or a chain. When the first drive assembly is driven by a chain, the end of the first rotating shaft 121 away from the mounting frame 11 is detachably connected to a driven sprocket. The first drive assembly includes a driving sprocket. The driven sprocket and the driving sprocket are connected by a chain transmission. The driving sprocket is driven to rotate by a driving member such as a first motor or a handle. The driving sprocket is driven to rotate by the first motor or the handle, and the driving sprocket drives the driven sprocket to rotate through the chain, thereby realizing the rotation of the mounting frame 11 around the first axis. At the same time, since the ray detection displacement assembly includes several mounting frames 11, all mounting frames 11 can be driven by the same driving sprocket, thereby realizing the synchronous rotation of all the parts to be detected 4. Of course, one driving sprocket can also be used to drive one mounting frame 11 to move, or one driving sprocket can be used to drive several mounting frames 11 to move. And the starting postures of all the parts to be detected 4 can also be different.

[0029] When the first driving component adopts belt transmission, the first driving component includes a pulley 122, and the pulley 122 is detachably connected to the first rotating shaft 121. The adjacent pulleys 122 are driven by the belt 123, and any pulley 122 is driven by the first driving member. That is, any pulley 122 is driven to rotate by the first driving member, and the adjacent pulleys 122 are driven by the belt, thereby driving all the first rotating shafts 121 to rotate, and then realizing the rotation of the mounting frame 11 around the first axis, so as to realize the synchronous rotation of all the parts to be detected 4; the above structure is to drive all the pulleys 122 to rotate by a first driving member. Of course, a first driving member can also be used to drive a mounting frame 11 to move, or a first driving member can be used to drive several mounting frames 11 to move. And the starting postures of all the parts to be detected 4 can also be the same or different.

[0030] In this embodiment, the first driving member can be a motor or a crank structure. When the first driving member is a motor, the motor drives the pulley 122 to rotate, thereby realizing the rotation of the mounting frame 11. When the first driving member adopts a crank structure, the crank and the pulley 122 are detachably connected, and the crank drives the pulley 122 to rotate. In this structure, an angle plate is provided on the outside of the crank, which can accurately control the rotation angle of the first rotating shaft 121 and the mounting frame 11.

[0031] Preferably, the second rotational motion part 13 of this embodiment adopts shaft rotation; the second rotational motion part 13 includes a rotating frame 131, the rotating frame 131 is rotatably connected with the first rotating element, the second rotating element is a second rotating shaft 132, the second rotating shaft 132 and the rotating frame 131 are detachably connected, and the second rotating shaft 132 is driven to rotate by a second driving element. The second rotating shaft 132 is driven to rotate by the second driving element, and the second rotating shaft 132 drives the rotating frame 131 to rotate around the second axis. At this time, the second axis is the axis of the second rotating shaft 132. The shaft rotation adopted in this embodiment can achieve large-angle rotation. In this embodiment, the second driving element can be a second motor, and the second motor drives the second rotating shaft 132 to rotate. Of course, a speed regulator can also be provided between the output shaft of the second motor and the second rotating shaft 132 to accurately control the rotation angle of the second rotating shaft 132.

[0032] The present embodiment also discloses a blade radiation detection mechanism, including a radiation detection displacement assembly 1, a frame 2 and a detector 3. The detected part 4 is a blade to be detected. The frame 2 is rotatably connected to the second rotating motion part 13. The detector 3 is arranged on one side of the blade to be detected. The detector 3 is used to record the radiation intensity after the radiation penetrates the blade to be detected.

[0033] When this embodiment is working, the blade to be detected is detachably connected to the mounting frame 11 in the radiation detection displacement component 1, and the detector 3 records the radiation intensity after the radiation penetrates the blade to be detected, thereby realizing radiation detection of the blade to be detected; during the detection process, the radiation detection displacement component 1 adjusts the rotational posture of the component to be detected 4 through the first rotational motion part 12, and adjusts the pitch angle of the component to be detected 4 through the second rotational motion part 13, thereby realizing the displacement of the component to be detected 4, thereby realizing multi-angle radiation detection of the blade to be detected; and the angle adjustment of the blade to be detected through the first rotational motion part 12 and the second rotational motion part 13 is more convenient, simple to operate, and stable and reliable.

[0034] In a further optimized solution, the blade X-ray detection mechanism also includes a third movable motion part, which is connected to the frame 2 and includes a third movable end connected to the detector 3. Based on the movement of the third movable end, the distance between the detector 3 and the mounting frame 11 is controlled. The third movable motion part controls the movement of the third movable end and the detector 3, thereby controlling the distance between the detector 3 and the mounting frame 11. After adjusting the pitch angle of the object to be detected 4 by the second rotating motion part 13, the present application expands or shortens the distance between the two to meet the distance requirement between the detector 3 and the blade to be detected. At the same time, the distance between the blade to be detected and the detector 3 can also be adjusted to obtain the X-ray imaging of the object to be detected at different recording distances.

[0035] In this solution, the third movable motion part can be lifted, lowered, translated, and other methods to adjust the distance between the detector 3 and the mounting bracket 11. In this embodiment, the third movable motion part is lifted, and the lifting method can also be implemented by a variety of structures, such as direct drive methods such as air cylinders, hydraulic cylinders, and electric cylinders, that is, the fixed end of the cylinder body is detachably connected to the frame 2, and the movable end of the cylinder body is detachably connected to the detector 3. By controlling the extension or contraction of structures such as air cylinders, hydraulic cylinders, and electric cylinders, the distance between the detector 3 and the mounting bracket 11 is adjusted. The third movable motion part can also be lifted in the form of a screw-nut. The above structures can all be controlled by an electric control structure.

[0036] In this embodiment, the third movable motion part uses a manually controlled lifting method to adjust the distance between the detector 3 and the mounting frame 11.

In the process of lifting or lowering the second pull rod 25, the first rotating rod 22 and the second rotating rod 23 will be driven to rotate. During the rotation of the first rotating rod 22, since the first pull rod 24 is slidably connected to the tray 21 along the first axis direction, while driving the first pull rod 24 to rise or fall, the first pull rod 24 will slide along the first axis direction, so that the first pull rod 24 supports the tray 21 to ensure the stability of the tray 21 relative to the frame 2.
