Description

Technical Field

[0001] The present application belongs to the technical field of X-ray detection, and in particular, relates to an X-ray detection auxiliary device and a method of using the same. Background Art

[0002] X-ray flaw detection is a non-destructive flaw detection method commonly used in the production process of industrial metal products. It can detect the internal quality of products and reduce the risk of product breakage during use. X-ray detection is when X-rays penetrate the tissue to be tested, due to the different density and thickness of the tissue, different shades of color appear on the film. The internal defects of the tissue to be tested are evaluated based on the shape, size, depth, etc. of the color distribution on the film.

[0003] When cylindrical metal materials are X-rayed, their thickness changes from small to large and from large to small, so the images presented on the film are from dark to shallow and from shallow to dark, which makes it impossible to determine and grade defects, ultimately resulting in the inability to achieve X-ray detection of cylindrical metal materials. In the prior art, the methods for non-destructive flaw detection of cylindrical metal materials include: using a terahertz three-dimensional tomography system to achieve non-destructive flaw detection of cylindrical materials, or using a compensation block for thickness compensation.

[0004] However, the terahertz three-dimensional tomography system is expensive, and this equipment is mostly used for non-destructive testing of non-metallic materials and composite materials. When using compensation blocks to compensate for the thickness of cylindrical metal materials, they must be rearranged after each shot, and each cylindrical metal material needs to be tested in both the X-axis and Y-axis directions to determine the defect volume and position and avoid missed detection, which makes the actual operation time-consuming and labor-intensive. For mass-produced products, the detection efficiency is very low. Summary of the invention

[0057] Reference Figure 1The present application provides an X-ray detection auxiliary device, including a base assembly 100, a compensation member 200 and a driving assembly 300; wherein the compensation member 200 is arranged on the base assembly 100, and a plurality of through holes 201 are penetrated on the compensation member 200, and each through hole 201 is used to accommodate a cylindrical object to be tested, and the driving assembly 300 is arranged on the base assembly 100, and the driving assembly 300 is connected to the cylindrical object to be tested, and the driving assembly 300 is used to drive the cylindrical object to be tested to rotate relative to the compensation member 200, and / or, the driving assembly 300 is used to push the cylindrical object to be tested out of the through hole 201.

[0058] Reference Figures 1 to 3 In some embodiments, the base assembly 100 includes a fixed seat 101 and a support frame 102. The fixed seat 101 is used to install the driving assembly 300. One end of the support frame 102 is fixed on the fixed seat 101, and the other end of the support frame 102 is used to support the compensation member 200 so that the compensation member 200 and the fixed seat 101 are separated by a preset distance.

[0059] Specifically, the fixed seat 101 is arranged on a plane in the X-ray detection area, one end of the support frame 102 is fixed on the fixed seat 101, and the other end of the support frame 102 is fixedly connected to the compensation member 200. The support frame 102 is used to support the compensation member 200 so that it is separated from the fixed seat 101 by a preset distance. The support frame 102 is also used to make the through hole 201 on the compensation member 200 face the driving component 300, so that the driving component 300 installed on the fixed seat 101 can drive the cylindrical object to be tested in the through hole 201 to move; in some embodiments, two support frames 102 are provided to ensure that the compensation member 200 is stably arranged on the fixed seat 101.

[0060] It should be noted that the support frame 102 separates the compensation member 200 and the fixed seat 101 by a preset distance. The preset distance is usually used to install the drive component 300. In actual applications, the stroke of the actuating end of the drive component 300 also needs to be considered. Therefore, the preset interval should be set based on the external dimensions of the drive component 300 and the stroke of the actuating end of the drive component 300.

[0061] Reference Figure 1 and Figure 2 In some embodiments, the compensating member 200 is disposed on the base assembly 100, and a plurality of through holes 201 are formed on the compensating member 200, each of the through holes 201 being used to accommodate a cylindrical object to be tested; the inner diameter of the through hole 201 is not less than the maximum circular cross-sectional diameter of the cylindrical object to be tested, and the spacing between the two ends of the through hole 201 is not less than the maximum height of the cylindrical object to be tested.

[0062] Specifically, the compensating part 200 is made of the same material as the cylindrical object to be measured. Before making the compensating part 200, it is necessary to ensure that the internal structure of the material making the compensating part 200 is uniform and defect-free; the inner diameter of the through hole 201 on the compensating part 200 is not less than the maximum circular cross-sectional diameter of the cylindrical object to be measured. Preferably, the inner diameter of the through hole 201 on the compensating part 200 is equal to the maximum circular cross-sectional diameter of the cylindrical object to be measured, and the error does not exceed 0.1mm; the spacing between the two ends of the through hole 201 on the compensating part 200 is not less than the maximum height of the cylindrical object to be measured. Preferably, the spacing between the two ends of the through hole 201 is greater than the maximum height of the cylindrical object to be measured, which is 0.5cm.

[0063] It should be noted that since a compensating member 200 needs to simultaneously mount multiple cylindrical objects to be tested, and the through hole 201 on the compensating member 200 needs to completely wrap the cylindrical objects to be tested, the overall size of the compensating member 200 should be set according to the actual situation based on the size of the cylindrical objects to be tested.

[0064] In some embodiments, the driving assembly 300 further includes a first mounting seat, a first transmission member and a first longitudinal driving member; a plurality of first transmission members are arranged at one end of the compensation member 200 corresponding to the through holes 201, one end of the first transmission member extends into the through hole 201 and is connected to the cylindrical object to be tested, the other end of the first transmission member is arranged on the first mounting seat, the first longitudinal driving member is arranged on the base assembly 100, the actuating end of the first longitudinal driving member is connected to the first mounting seat, and the first longitudinal driving member is used to push the cylindrical object to be tested out of the through hole 201 through the mounting seat and the first transmission member.

[0065] Specifically, the first longitudinal driving member is a cylinder arranged on the fixed seat 101, and the first longitudinal driving member includes an input end and an actuating end. The input end of the first longitudinal driving member is electrically connected to the power supply, and the actuating end of the first longitudinal driving member is connected to the first mounting seat. Based on the number of cylindrical objects to be tested, a corresponding number of first transmission members are arranged on the first mounting seat. The first longitudinal driving member pushes the first mounting seat, thereby simultaneously pushing the multiple first transmission members on the first mounting seat to move axially along the cylindrical object to be tested, thereby achieving the purpose of simultaneously pushing out the multiple cylindrical objects to be tested in the through hole 201, thereby improving the detection efficiency during large-scale detection.

[0066] In some embodiments, the driving assembly 300 further includes a second mounting seat, a second transmission member and a first transverse driving member; the second mounting seat is arranged on the base assembly 100, and a plurality of second transmission members are arranged at one end of the compensation member 200 corresponding to the through holes 201, one end of the second transmission member extends into the through hole 201 and is connected to the cylindrical object to be tested, and the other end of the second transmission member is rotatably arranged on the mounting seat, and the first transverse driving member is arranged on the base assembly 100, and the actuating end of the first transverse driving member is connected to the second transmission member, and the first transverse driving member is used to rotate the cylindrical object to be tested relative to the compensation member 200 through the second transmission member; the gear sleeve 400 is fixedly arranged outside the second transmission member, and the spur rack 500 is arranged on one side of the gear sleeve 400 and meshed with it, and the spur rack 500 is connected to the actuating end of the first transverse driving member.

[0067] Specifically, the second mounting seat is fixed on the support frame 102. Based on the number of cylindrical objects to be tested, a corresponding number of second transmission members are rotatably arranged on the second mounting seat. The gear sleeve 400 is fixed outside the second transmission member. The first transverse driving member is a cylinder arranged on the fixed seat 101. The first transverse driving member includes an input end and an actuating end. The input end of the first transverse driving member is electrically connected to the power supply. The actuating end of the first transverse driving member is meshed and connected with the gear sleeve 400 on the second transmission member through a spur rack 500. The first transverse driving member drives the multiple second transmission members to rotate relative to the second mounting seat through the spur rack 500 and the gear sleeve 400, thereby achieving the purpose of rotating the multiple cylindrical objects to be tested in the through hole 201 at the same time. In the X-ray detection process, the cylindrical objects to be tested need to be detected separately in two directions perpendicular to each other. When the detection in the X-axis direction is changed to the Y-axis direction detection, it is avoided to rearrange the multiple cylindrical objects to be tested one by one, thereby improving the detection efficiency.

[0068] Reference Figures 1 to 3In some embodiments, the driving assembly 300 further includes a third mounting seat 301, a third transmission member 302, a second longitudinal driving member 303 and a second transverse driving member 304; a plurality of third transmission members 302 are arranged at one end of the compensation member 200 corresponding to the through hole 201, one end of the third transmission member 302 extends into the through hole 201 and is connected to the cylindrical object to be measured, and the other end of the third transmission member 302 is rotatably arranged on the mounting seat, the second longitudinal driving member 303 is arranged on the base assembly 100, the actuating end of the second longitudinal driving member 303 is connected to the mounting seat, and the second longitudinal driving member 303 is arranged on the base assembly 100. 03 is used to push the cylindrical object to be tested out of the through hole 201 through the mounting seat and the third transmission member 302. The second transverse driving member 304 is arranged on the base assembly 100. The actuating end of the second transverse driving member 304 is connected to the third transmission member 302. The second transverse driving member 304 is used to rotate the cylindrical object to be tested relative to the compensation member 200 through the third transmission member 302; the gear sleeve 400 is fixedly arranged outside the third transmission member 302, and the spur rack 500 is arranged on one side of the gear sleeve 400 and meshed with it. The spur rack 500 is connected to the actuating end of the second transverse driving member 304.

[0069] Specifically, the second longitudinal driving member 303 is a cylinder arranged on the fixed seat 101, and the second longitudinal driving member 303 includes an input end and an actuating end. The input end of the second longitudinal driving member 303 is electrically connected to the power supply, and the actuating end of the second longitudinal driving member 303 is connected to the third mounting seat 301. Based on the number of cylindrical objects to be tested, a corresponding number of third transmission members 302 are arranged on the third mounting seat 301. The second longitudinal driving member 303 pushes the third mounting seat 301, thereby simultaneously pushing the multiple third transmission members 302 on the third mounting seat 301 to move axially along the cylindrical object to be tested, thereby achieving the purpose of simultaneously pushing out the multiple cylindrical objects to be tested in the through hole 201.

[0070] Reference Figure 4 The gear sleeve 400 is fixedly arranged outside the third transmission member 302. The second transverse driving member 304 is a cylinder arranged on the fixed seat 101. The second transverse driving member 304 includes an input end and an actuating end. The input end of the second transverse driving member 304 is electrically connected to the power supply. The actuating end of the second transverse driving member 304 is meshed and connected with the gear sleeve 400 on the third transmission member 302 through the spur rack 500. The second transverse driving member 304 drives multiple third transmission members 302 to rotate relative to the third mounting seat 301 through the spur rack 500 and the gear sleeve 400, thereby achieving the purpose of rotating multiple cylindrical objects to be tested in the through hole 201 at the same time.

[0071] Based on the cooperation of the third mounting seat 301, the third transmission member 302, the second longitudinal driving member 303 and the second transverse driving member 304, during the X-ray detection process, it is necessary to detect the cylindrical objects to be tested in two directions perpendicular to each other. When the detection in the X-axis direction is changed to the Y-axis direction detection, the second transverse driving member 304 rotates the multiple cylindrical objects to be tested in the through hole 201 at the same time through the spur rack 500 and the gear sleeve 400, avoiding rearranging the multiple cylindrical objects to be tested one by one, and when replacing the next batch of cylindrical objects to be tested, the second longitudinal driving member 303 pushes the cylindrical objects to be tested in the compensation member 200 at the same time through the third mounting seat 301 and the third transmission member 302, thereby greatly improving the detection efficiency.

[0072] Reference Figures 1 to 3 In some embodiments, the fixed seat 101 further includes a first part and a second part, the first part is used to install the second longitudinal driving member 303 and the support frame 102, the second longitudinal driving member 303 is located between the first part and the compensation member 200, and the second part is vertically arranged on the first part, and the second part is used to install the first transverse driving member or the second transverse driving member 304, so that the first transverse driving member or the second transverse driving member 304 is located on one side of the compensation member 200.

[0073] Specifically, the first part is arranged on a plane in the X-ray detection area, and the maximum surface of the first part is parallel to the plane. The compensation member 200 is arranged on the first part through the support frame 102, and the through hole 201 on the compensation member 200 faces the first part. The second longitudinal driving member 303 is located between the first part and the compensation member 200. The second longitudinal driving member 303 pushes the cylindrical object to be tested away from the first part through the third transmission member 302 and the third mounting seat 301, so as to facilitate the operator to load and unload the cylindrical object to be tested from above the compensation member 200.

[0074] The second part is vertically arranged on the first part, and the second part is used to install the first transverse driving member or the second transverse driving member 304, so that the first transverse driving member or the second transverse driving member 304 is located on one side of the compensation member 200, which is convenient for the first transverse driving member or the second transverse driving member 304 to drive the gear sleeve 400 to rotate through the spur rack 500, and will not affect the operation of the second longitudinal driving member 303 to push the cylindrical object to be tested.

[0075] Reference Figure 2 and Figure 3 In some embodiments, two limit members 600 are respectively disposed on both sides of the first lateral driving member or the second lateral driving member 304, and the limit members 600 are used to limit the stroke of the spur rack 500, thereby limiting the rotation angle of the cylindrical object to be measured.

[0076] Specifically, during the X-ray inspection process, since the cylindrical object to be tested needs to be inspected separately in two directions perpendicular to each other to determine the defect volume and position and avoid missed detection, it is necessary to limit the rotation angle of the cylindrical object to be tested each time so that it rotates 90° each time; by arranging two limit members 600 on the actuating end of the first transverse driving member or the actuating end of the second transverse driving member 304 respectively, so as to limit the stroke of the spur rack 500 driven by it to πd / 4, where d is the pitch circle diameter of the gear sleeve 400, thereby limiting the rotation angle of the gear sleeve 400, and further limiting the rotation angle of the cylindrical object to be tested to 90° each time; in some embodiments, the limit member 600 is a limit screw.

[0077] It should be noted that the connection between the second transmission member or the third transmission member 302 and the cylindrical object to be tested is usually set to a detachable connection. In some embodiments, a straight groove is provided at one end of the cylindrical object to be tested, and a straight edge is correspondingly provided on the second transmission member or the third transmission member 302 to achieve the purpose of the second transmission member or the third transmission member 302 driving the cylindrical object to be tested to rotate.

[0082] In some embodiments, the detection step S2 includes, using X-ray detection to obtain an image of the cylindrical object to be tested in a first direction by installing a compensation piece 200 on the cylindrical object to be tested, and then using a driving component 300 to drive the cylindrical object to be tested to rotate 90° around its axis, and then using X-ray detection to obtain an image of the cylindrical object to be tested in a second direction by installing the compensation piece 200 on the cylindrical object to be tested.

[0083] Specifically, after the film is installed, the X-ray detection is turned on and the compensating member 200 of the cylindrical object to be tested is installed to obtain an image of the cylindrical object to be tested in the first direction. The straight rack 500 is driven to move a distance of πd / 4 by the second transverse driving member 304, thereby driving the cylindrical object to be tested to rotate 90° around its axis. Then, another film is replaced, and the X-ray detection is turned on again and the compensating member 200 of the cylindrical object to be tested is installed to obtain an image of the cylindrical object to be tested in the second direction. The first direction and the second direction are perpendicular to each other.

[0084] In some embodiments, the disassembly step S3 includes moving the cylindrical object to be tested along its axis through the driving assembly 300 so that the cylindrical object to be tested is pushed out of the compensation member 200, and completing the disassembly by removing the cylindrical object to be tested and resetting the driving assembly 300.

[0085] Specifically, the second longitudinal driving member 303 pushes the cylindrical object to be tested to move along its axial direction through the third mounting seat 301 and the third transmission member 302, so that the cylindrical object to be tested is pushed out of the compensation member 200 from the end of the compensation member 200 away from the support frame 102. By removing the cylindrical object to be tested, the actuating end of the second longitudinal driving member 303 moves toward the direction close to the support frame 102 to reset, and the actuating end of the second transverse driving member 304 is displaced a distance of πd / 4 in the opposite direction of the detection step S2 to reset, thereby completing the disassembly.

[0086] The present application provides an X-ray detection auxiliary device and a method for using the same. A compensation member 200 is used to perform thickness compensation on a plurality of cylindrical objects to be detected. A driving assembly 300 is used to simultaneously drive the plurality of cylindrical objects to be detected to move relative to the compensation member 200. X-ray detection of the plurality of cylindrical objects to be detected in two directions perpendicular to each other, i.e., the X-axis and the Y-axis, is quickly completed without disassembling the compensation member 200, thereby improving the detection efficiency. The first mounting seat, the first transmission member, and the first longitudinal driving member are used to cooperate with each other to quickly push the plurality of cylindrical objects to be detected out of the compensation member 200, thereby improving the detection efficiency. The second mounting seat, the second transmission member, and the first transverse driving member are used to quickly rotate the plurality of cylindrical objects to be detected by a preset angle, thereby improving the detection efficiency. The third mounting seat 301, the third transmission member 302, the second transverse driving member 304, and the second longitudinal driving member 303 are used to quickly rotate the plurality of cylindrical objects to be detected by a preset angle for two detections, and the plurality of cylindrical objects to be detected are quickly pushed out of the compensation member 200 for the next round of detection, thereby greatly improving the batch detection efficiency.
