Description

Technical Field

[0001] This utility model belongs to the field of X-ray digital imaging inspection technology, specifically relating to a small workpiece X-ray digital imaging batch inspection device. Background Technology

[0002] During the manufacturing process, metal or non-metal workpieces typically undergo X-ray inspection to ensure their internal quality meets requirements. When performing X-ray digital imaging inspection, to obtain clear and accurate images, the inspection surface of the workpiece should be as perpendicular as possible to the direction of the main beam emitted by the X-ray machine, and as parallel as possible to the plane of the detector. This allows the X-rays to penetrate the workpiece uniformly, reduces image distortion and information loss caused by workpiece tilt, improves the quality of the imaging film, and ensures the reliability of the inspection results.

[0003] When performing digital X-ray inspection on a workpiece, to ensure the inspection surface is perpendicular to the main beam direction of the X-ray machine, the workpiece needs to be vertically erected on the inspection platform. However, due to the small thickness of the workpiece, it is difficult to directly and stably erect it vertically on the inspection platform. Currently, for inspecting such workpieces, two metal blocks are mostly used to clamp the workpiece to maintain its verticality, or a heavy auxiliary support tool is used. However, both methods have the following drawbacks:

[0004] 1) Using metal blocks to clamp the workpiece. To prevent the metal blocks from obscuring parts of the workpiece's inspection surface and causing missed inspections, the worker needs to rotate the workpiece after each X-ray examination and re-examine the parts that were obscured by the metal blocks during the previous examination. Although this method of manually clamping and fixing the workpiece can keep it perpendicular to the inspection platform, it cannot guarantee that the workpiece's inspection surface is perpendicular to the direction of the X-ray machine's main beam and parallel to the plane of the detector.

[0005] 2) Using a heavy auxiliary support tool to support the workpiece. To ensure the stability of the workpiece, the auxiliary support tool is often heavy and made of high-density material. However, this method can also lead to the workpiece's inspection surface being obstructed, causing missed detections and requiring the workpiece to be flipped over and the obstructed part to be re-examined. Moreover, this method often results in the workpiece tilting, making it impossible to ensure that the workpiece is vertically upright on the inspection platform, and it is also impossible to ensure that its inspection surface is parallel to the plane of the detector.

[0006] 3) When inspecting a large number of such workpieces, if the method of holding them with metal blocks and rotating them repeatedly is still used, the staff will need to repeatedly enter and exit the lead room during the inspection process, and frequently move, replace and rotate the workpieces. This not only cannot guarantee the reliability of the imaging film, but also results in high labor intensity, extremely low efficiency, and ionizing radiation pollution, which will harm the health of the staff. Utility Model Content

[0007] To address the aforementioned technical problems in the background art, this utility model provides a small-scale workpiece radiographic digital imaging batch inspection device. In the existing radiographic digital imaging inspection system, the vertical lifting mechanisms of the detector and X-ray source can be linked and controlled by the inspection system (both can rise and fall simultaneously at the same horizontal height and speed). The X-ray source and the inspection platform are concentric and coaxial. Based on the fact that the inspection platform can rotate 360 ​​degrees around the X-ray source, and utilizing the low density and high strength of the upper plate material, it can effectively support and clamp the workpiece. Furthermore, it is not easy to form an image on the transmission film during radiographic inspection, thus not affecting the film evaluation.

[0008] The technical solution of this utility model is as follows: This utility model is a small workpiece digital imaging batch inspection device, which is special in that: the small workpiece digital imaging batch inspection device includes a workpiece fixture, the workpiece fixture includes an arc-shaped fixed base, two vertical plates and two adjustable plates. A rectangular groove is provided at the center of the upper surface of the arc-shaped fixed base. The length direction of the rectangular groove is parallel to the tangent of the arc surface of the arc-shaped fixed base. The two vertical plates are arranged parallel to each other in the rectangular groove and are located on both sides of the length direction of the rectangular groove. The two adjustable plates are located in the rectangular groove and are embedded in the middle of the two vertical plates. The two adjustable plates are connected by two springs. Each vertical plate has two screw holes symmetrically arranged. Four set screws pass through the screw holes on the two vertical plates respectively. The inner ends of the set screws abut against the adjustable plates. Two upper plates are symmetrically arranged on the upper inner side of each adjustable plate. The upper plates are connected to the adjustable plates by adjusting bolts.

[0009] Furthermore, a keyway is provided along the length of the adjustable plate, and a scale is provided above the keyway. The "0" mark on the scale coincides with the center line of the keyway and the center line along the length of the adjustable plate. The adjusting bolt is located inside the keyway and can slide left and right along the keyway.

[0010] Furthermore, an "L"-shaped groove extending downwards along the top edge is provided on the upper inner side of the upper plate.

[0011] Furthermore, the two springs are arranged in parallel and symmetrical configuration.

[0012] Furthermore, a threaded hole is provided on each side of the arc-shaped fixed base, and a fastening bolt is provided on the threaded hole.

[0013] Furthermore, the small workpiece radiographic digital imaging batch inspection device also includes an inspection platform. The inspection platform is circular and rotatable, and an arc-shaped fixed base is set on the inspection platform through fastening bolts and threaded holes.

[0014] Furthermore, there are multiple workpiece fixtures, evenly distributed around the inspection platform.

[0015] Furthermore, the spring is a high-strength, pressure-resistant metal spring, the adjusting bolt is a stainless steel M8 bolt, the set screw is a stainless steel M5 screw, and the fastening bolt is a commonly used stainless steel M12 bolt.

[0016] Furthermore, the curved fixed base, vertical plate, and adjustable plate are all made of aluminum metal.

[0017] Furthermore, the upper panel is made of polystyrene.

[0018] This utility model provides a small-scale workpiece digital imaging batch inspection device, which is applied to the existing digital imaging inspection system. The vertical lifting mechanism of the detector and X-ray source of the digital imaging inspection system can be linked through the inspection system (both can rise and fall at the same horizontal height and speed). The X-ray source and the inspection platform are concentric and coaxial. Based on the fact that the inspection platform of this utility model can rotate 360 ​​degrees around the X-ray source, it utilizes the low density and high strength of the upper plate material to effectively support and clamp the workpiece. During X-ray inspection, it is unlikely to form an image on the transmission film, thus not affecting the film evaluation. The device includes: an arc-shaped fixed base, two vertical plates, four upper plates, two adjustable plates, and a workpiece clamp consisting of two springs, eight adjusting bolts, four set screws, and two fastening screws. The fastening screws fix the arc-shaped fixed base to the inspection platform. The two vertical plates are welded to the arc-shaped base; the two adjustable plates are connected and fixed by two springs and embedded in the rectangular groove between the two vertical plates. Screwing in or out the set screw causes the spring to contract or extend, moving the two adjustable plates back and forth to clamp workpieces of different thicknesses in the thickness direction. Eight adjusting bolts connect and fix the four upper plates and the two adjustable plates. These bolts slide left and right within the keyways on the adjustable plates, moving the upper plates on either side of the "0" mark to clamp workpieces of different widths in the width direction. Each of the four upper plates has a 10mm deep "L"-shaped groove, the bottom of which protrudes 20mm above the edge of the adjustable plate. This supports the workpiece and ensures that there is no high-density material obstructing the X-ray source, workpiece, and detector during X-ray inspection. Several identical workpiece fixtures are manufactured, evenly distributed, and fixed on the inspection platform for multi-station inspection. The programmable function of the inspection system allows setting a target angle, causing the inspection platform to rotate the fixtures and workpieces around the X-ray source. Once the target angle is reached, rotation pauses for 5 seconds for automatic radiographic imaging, achieving efficient batch inspection. In this invention, the detection platform aligns the center of the X-ray source, the center of the workpiece detection surface, and the center of the detector with a straight line at each target angle, ensuring that the workpiece detection surface is perpendicular to the direction of the main X-ray beam. Therefore, this invention has the following advantages:

[0019] 1) This utility model can improve the quality of radiographic imaging film and ensure the reliability of test results.

[0020] 2) This utility model, through its adjustable function design, is applicable to a variety of workpieces of different sizes, enabling multi-station inspection. Multiple workpieces can be placed at once and inspected at one time, effectively shortening the inspection time and improving work efficiency.

[0021] 3) The workpiece tool used in this utility model is simple to operate and easy to clamp, and can quickly change workpieces, which greatly reduces the workload and labor intensity of personnel and improves work efficiency; it also reduces safety risks and avoids personnel being exposed to ionizing radiation environment for a long time, which may cause damage to personnel's health.

[0022] 4) This utility model has a wide range of applications. Its adjustable function can be applied to the X-ray inspection of square, round or irregularly shaped workpieces with a width of ≤410mm (detector panel size 427mm*427mm, effective illumination area of ​​427mm*427mm).

[0029] The overall scheme of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0030] See Figure 1 , 2 The structure of this utility model includes a workpiece fixture and a detection platform 12. The detection platform 12 is circular, and multiple screw holes for fixing are evenly distributed near the outer edge of the detection platform 12.

[0031] The workpiece fixture includes an arc-shaped fixed base 1, two vertical plates 2, two adjustable plates 3, four upper plates 4, two springs 5, eight adjusting bolts 6, four set screws 7, and two fastening screws 8.

[0032] An arc-shaped fixing base 1 is made according to the outer arc of the detection platform 12. A rectangular groove 9 with a depth of 20mm is provided at the center of the upper surface of the arc-shaped fixing base 1, and its length direction is parallel to the tangent of the arc surface of the arc-shaped fixing base.

[0033] Two fastening screws 8 pass through the screw holes evenly distributed on both sides of the arc-shaped fixed base 1 and near the outer edge of the detection platform 12, respectively, to fix the arc-shaped fixed base 1 onto the detection platform 12.

[0034] Each of the two vertical plates 2 has a threaded hole on one side; the vertical plates 2 are fixed to the arc-shaped fixed base 1 by welding, located on both sides of the length direction inside the rectangular groove 9, and closely attached to the upper and lower edges of the rectangular groove 9.

[0035] Both adjustable plates 3 have keyways 11, with a scale above each keyway 11, the "0" mark located at the center of the keyway 11. A spring 5 is welded to each side of the two adjustable plates 3 for connection, with the two springs 5 ​​arranged parallel and symmetrically, their central axes 80mm from the lower edge of the adjustable plate 3. The connected two adjustable plates 3 are embedded in a rectangular groove 9 between the two vertical plates 2. The rectangular groove 9 prevents the two adjustable plates 3 from moving left or right. Four set screws 7 pass through the threaded holes on the two vertical plates 2, with the inner ends of the set screws 7 abutting against the adjustable plates 3. Screwing the set screws 7 in and out causes the springs 5 ​​to contract or extend, moving the two adjustable plates 3 back and forth, thus adjusting the distance between them and achieving the purpose of clamping workpieces of different thicknesses in the thickness direction.

[0036] Each of the four upper plates 4 has an L-shaped groove 10 extending downwards from its top edge, 10mm deep. Below each L-shaped groove 10 on the upper plate 4 are two screw holes. Two adjusting bolts 6 pass through the keyway 11 and the screw holes on the upper plate 4, connecting and fixing the upper plate 4 and the adjustable plate 3. Every two upper plates 4 are connected and fixed to one adjustable plate 3. The adjusting bolts 6 can slide left and right within the keyway 11, causing the upper plates 4 on both sides of the "0" mark to move left and right, achieving the purpose of clamping workpieces of different widths in the width direction. At this time, the center line of the workpiece's width direction coincides with the "0" mark.

[0037] The lowest point of the "L"-shaped grooves 10 on the four upper plates 4 is 20mm higher than the upper edge of the adjustable plate 3, so as to support the workpiece and ensure that there is no high-density material blocking the X-ray source, workpiece and detector during X-ray inspection.

[0038] Spring 5 is a high-strength, pressure-resistant metal spring; adjusting bolt 6 is a stainless steel M8 bolt; set screw 7 is a stainless steel M5 screw; and fastening bolt 8 is a commonly used stainless steel M12 bolt.

[0039] The curved fixed base 1, the vertical plate 2, and the adjustable plate 3 are all made of aluminum metal.

[0040] The upper plate 4 is made of polystyrene.

[0041] Several identical workpiece fixtures are fabricated and evenly distributed on a circular inspection platform 12 to achieve multi-station inspection. Using the programmable function of the inspection system, a target angle is set, causing the inspection platform 12 to rotate the workpiece fixtures and workpieces around the X-ray source 13. Once the target angle is reached, the rotation pauses for 2 seconds to automatically perform radiographic imaging, achieving efficient batch inspection.

[0042] The detection platform 9 can also be a device available in the existing X-ray digital imaging detection system.

[0043] See Figure 3 In this utility model, the inner top vertices of the "L"-shaped grooves 10 on the two upper plates 4 of the inner adjustable plate 3 are points a1 and a2, and the outer bottom low points of the "L"-shaped grooves 10 are points b1 and b2. Correspondingly, the inner top vertices of the "L"-shaped grooves 10 on the two upper plates 4 of the outer adjustable plate 3 are points a3 and a4, and the outer bottom low points of the "L"-shaped grooves 10 are points b3 and b4.

[0044] Based on the workpiece thickness, screw the four set screws 7 in or out by the same distance so that on the upper plate 4: the distance from point a1 to a3 = the distance from point a2 to a4 = the workpiece thickness + 2mm (2mm more than the workpiece thickness, so that it can be easily picked up when changing to the next workpiece).

[0045] According to the workpiece width, slide eight adjusting bolts 6 in the keyway 11 so that the four upper plates 4 move the same distance to the left and right sides of the keyway 11 with the "0" mark on the adjustable plate 3 as the center. At this time, the distance from point b1 to b2 on the upper plate 4 should be equal to the distance from point b3 to b4, which should be equal to the workpiece width + 2mm (2mm more than the workpiece width, so that it can be easily picked up when changing to the next workpiece). Tighten the adjusting bolts 6.

[0046] The "L"-shaped grooves 10 on the four upper plates 4 at this time form a Hollow cavity. Place workpiece 13 to... Inside the cavity, the plane containing the bottom points b1, b2, b3, and b4 of the "L"-shaped groove 10 on the upper plate 4 supports the workpiece.

[0047] This method is used to uniformly fix n identical workpiece fixtures (and n workpieces) on the circular inspection platform 12.

[0048] See Figure 4 In application of this utility model, the detection system software controls the vertical lifting function of the X-ray source 13 and the detector 15, and adjusts the X-ray source lifting device 14 so that the line connecting the center of the X-ray source 13, the center of the detection surface of the workpiece 16, and the center of the detector 15 is a straight line. The workpiece 16 is a thin plate workpiece.

[0049] The target angle is determined to be 360 / n degrees. Through software programming, the inspection platform 12 is controlled to rotate automatically at a constant speed. Every 360 / n degrees, the inspection platform 12 stops rotating and remains stationary for 5 seconds. During this time, the inspection system transmits light and forms a digital radiographic film. After 5 seconds, the inspection platform 12 resumes rotation until one revolution is completed. At this point, all n workpieces have undergone digital radiographic imaging inspection.

[0050] Example 1

[0051] Digital X-ray imaging inspection was performed on a batch of disc-shaped workpieces with a diameter of 330 mm and a thickness of 12 mm.

[0052] The inspection process employed the traditional method of clamping the workpiece at its lower end with a metal block. After each radiograph, a worker entered the lead room, rotated the workpiece, and re-radiated the portion previously obscured by the metal block. Each workpiece required three entries into the lead room and three handling and turning operations, taking approximately two minutes. At this pace, completing 100 workpieces would require 300 entries and exits into the lead room and 300 manual rotations, totaling approximately 400 minutes of work time. Workers were exposed to ionizing radiation for approximately 400 minutes. Each workpiece required two radiographs, generating two films; a total of 200 films were needed to evaluate 100 workpieces.

[0053] If the workpiece is subjected to X-ray digital imaging inspection after being held by this novel practical device, the specific steps are as follows:

[0054] 1. Fastening screws 8 are passed through the threaded holes evenly distributed near the outer edge of the arc-shaped fixing base 1 and the detection platform 12 in sequence to fix the arc-shaped fixing base 1 on the detection platform 12. Ten arc-shaped fixing bases 1 are evenly fixed on the detection platform 12 in the same way.

[0055] 2. Based on the workpiece thickness of 12mm, screw the four set screws 7 in or out by the same distance so that the distance from point a1 to a3 on the upper plate 4 is equal to the distance from point a2 to a4, which is equal to the workpiece thickness + 2mm = 14mm.

[0056] 3. Based on the workpiece width = 330mm, slide the eight adjusting bolts 6 in the keyway so that the four upper plates 4 move 166mm to the left and right respectively with the "0" mark on the scale of the adjustable plate 3 as the center. At this time, on the upper plate 4: the distance from point b1 to b2 = the distance from point b3 to b4 = workpiece width + 2mm = 332mm. Tighten the adjusting bolts 6.

[0057] 4. Place workpieces #1 to #10 into the workpiece.

[0058] 5. The detection system software controls the vertical lifting function of the X-ray source 13 and the detector 15, so that the line connecting the center of the X-ray source 13, the center of the detection surface of the workpiece 16, and the center of the detector 15 is a straight line.

[0059] The target angle is determined to be 360 / 10 = 36 degrees. The detection system is programmable, and the detection platform 12 is controlled to automatically rotate at a constant speed around the X-ray source 13. Every 36 degrees of rotation, the detection platform 12 stops rotating and remains stationary for 5 seconds. During this time, the detection system transmits the X-ray and forms a digital film. After 5 seconds, the detection platform 12 resumes rotation until one full rotation is completed. At this point, all 10 workpieces have completed X-ray digital imaging inspection.

[0060] 6. Replace the workpiece with workpieces #11 to #20 and repeat the above process. Complete the inspection in sequence.

[0061] Each set of tests requires personnel to enter and exit the lead room twice, handle the workpiece twice, flip it 0 times, and hold 10 workpieces, taking approximately 5 minutes. At this pace, completing 100 workpieces requires 20 entries into the lead room, 20 handling and clamping operations, and approximately 50 minutes of work time; personnel are exposed to ionizing radiation for approximately 50 minutes, increasing work efficiency by 700%. One film is generated for each workpiece, requiring 100 films for 100 workpieces. This method significantly improves testing efficiency, reduces the safety risks for workers in ionizing radiation environments, and decreases the number of films requiring evaluation.

[0062] Example 2

[0063] Digital X-ray imaging inspection was performed on batches of square plate-shaped workpieces measuring 700mm in length, 400mm in width, and 20mm in thickness.

[0064] The previous method of clamping workpieces with metal blocks was used for inspection. From a safety perspective, because the workpieces are too long, if the metal blocks were used to clamp them in the width direction, there is a risk of the workpiece tipping over and damaging the inspection equipment as it moves with the inspection platform. Therefore, only both ends of the workpiece in the length direction are clamped (clamping only one end still poses a risk of tipping). During radiographic testing, the middle section (approximately 500mm long, larger than the detector's effective illumination area of ​​427mm x 427mm) needs to be radiographed twice, avoiding the metal blocks. After radiographing the middle section, the metal blocks are moved to the middle position, the inspection platform is moved, and both ends of the workpiece are radiographed again. Completing one workpiece requires personnel to enter the lead room 3 times, move the metal blocks once, and move the inspection platform 4 times, taking approximately 6 minutes. At this pace, completing 100 workpieces would require 300 entries into the lead room, 100 moves of the metal blocks, and 400 moves of the inspection platform, taking approximately 600 minutes of work time, during which personnel would be exposed to ionizing radiation for approximately 600 minutes. To complete one workpiece, four radiographs are required (two in the middle and one at each end), generating four negatives. A total of 400 negatives are needed to evaluate 100 workpieces.

[0065] If the workpiece is subjected to X-ray digital imaging inspection after being held by this novel practical device, the specific steps are as follows:

[0066] 1. The fastening screws 8 are passed through the threaded holes that are evenly distributed near the outer edge of the arc-shaped fixed base 1 and the detection platform 12 in sequence to fix the arc-shaped fixed base 1 on the detection platform 12. The same method is used to evenly fix 10 arc-shaped fixed bases 1 on the detection platform 12.

[0067] 2. Based on the workpiece thickness of 20mm, screw the four set screws 7 in or out by the same distance so that the distance from point a1 to a3 on the upper plate 4 is equal to the distance from point a2 to a4, which is equal to the workpiece thickness + 2mm = 22mm.

[0068] 3. Based on the workpiece width = 400mm, slide the eight adjusting bolts 6 in the keyway so that the four upper plates 4 move 201mm to the left and right respectively with the "0" mark on the scale of the adjustable plate 3 as the center. At this time, on the upper plate 4: the distance from point b1 to b2 = the distance from point b3 to b4 = workpiece width + 2mm = 402mm. Tighten the adjusting bolts 6.

[0069] 4. Place workpieces #1 to #10 into the workpiece.

[0070] 5. The detection system software controls the vertical lifting function of the X-ray source 13 and the detector 15, so that the center of the X-ray source 13, the center of the detection surface of the first part of the workpiece 16 to be detected (the workpiece length is 700mm, which is greater than the effective transmission height of the detector of 427mm, so the workpiece needs to be irradiated in two layers) and the center of the detector 15 are a straight line.

[0071] The top position (the highest point of the workpiece's inspection surface at this time) and bottom position (the lowest point of the workpiece's inspection surface at this time) of the X-ray source 13 and detector 15 are determined. The target angle is set to 360 / 10 = 36 degrees. Based on the determined top and bottom positions, the detection system automatically raises and lowers to perform two radiographic imaging operations on the workpieces, and the detection platform 12 rotates one full turn to complete the radiographic imaging of the upper half of 10 workpieces. Then, the X-ray source 13 and detector 15 automatically move down through the lifting function until the center of the X-ray source 13, the center of the inspection surface of the second inspection section of the workpiece 16, and the center of the detector 15 are aligned. The detection platform 12 continues to rotate one full turn to complete the radiographic imaging of the lower half of 10 workpieces. The detection platform 12 rotates twice at the set target angle to complete the X-ray digital imaging inspection of 10 workpieces.

[0072] 6. Replace the workpiece with workpieces 11# to 20#, and repeat the above process to complete the inspection in sequence.

[0073] All 10 workpieces were inspected. The entire process required personnel to enter the lead room twice, move the workpieces twice, move the metal blocks 0 times, hold the workpieces, rotate the inspection platform twice, and raise and lower the X-ray source and detector once, taking approximately 8 minutes. At this pace, 100 workpieces were inspected, requiring 20 entries into the lead room, 0 movement of the metal blocks, 20 rotations of the inspection platform, and 20 raising and lowerings of the X-ray source and detector, totaling approximately 160 minutes. Personnel were exposed to ionizing radiation for approximately 160 minutes, increasing work efficiency by 330%. Two films were generated for each workpiece (one for the upper layer and one for the lower layer), requiring a total of 200 films for the 100 workpieces. This method significantly improves inspection efficiency, reduces the safety risks for personnel working in an ionizing radiation environment, and reduces the workload of film evaluation by approximately 50%.
