Description

Technical Field

[0001] This utility model relates to the field of industrial CT equipment technology, and more specifically, to a flat panel detector adjustment mechanism and an industrial CT device. Background Technology

[0002] Industrial computed tomography (CT) equipment is a core precision testing device in the fields of industrial non-destructive testing, quality control, and reverse engineering.

[0003] In industrial CT equipment using related technologies, flat panel detectors mostly adopt a fixed installation structure, and their installation position and spatial posture remain fixed and cannot be adaptively adjusted.

[0004] Therefore, how to provide a flat panel detector adjustment mechanism that allows staff to easily adjust the orientation of the flat panel detector to improve imaging quality is a problem that urgently needs to be solved. Utility Model Content

[0005] In order to solve or improve the technical problem that the installation position and spatial attitude of the flat panel detector in the related technology remain fixed and cannot be adaptively adjusted, one objective of this utility model is to provide a flat panel detector adjustment mechanism.

[0006] Another objective of this invention is to provide an industrial CT device.

[0007] To achieve the above objectives, the first aspect of this utility model provides a flat panel detector adjustment mechanism, comprising: a fixed plate; an adjustment plate for connecting the flat panel detector; an adjustment shaft, one end of which passes through the fixed plate and is threadedly connected to the fixed plate; the other end of which is ball-jointed to the adjustment plate; the adjustment shaft is used to adjust the distance between the adjustment plate and the fixed plate; an attitude adjustment component, passing through the fixed plate and threadedly connected to the fixed plate, which abuts against the adjustment plate and adjusts the attitude of the adjustment plate; and a position locking component, passing through the fixed plate and the adjustment plate, which locks the position of the adjustment plate.

[0008] This utility model aims to provide a flat panel detector adjustment mechanism. By adjusting the rotating shaft, the attitude adjustment component, and the position locking component in coordination, the operator can adjust the rotation or pitch of the adjustment plate to adjust the attitude (including position and angle) of the flat panel detector. This is convenient and quick, and helps to improve the imaging quality of industrial CT equipment, thereby improving the detection accuracy.

[0009] It should be noted that the adjustment plate is connected to the fixed plate via an adjustment shaft, and there is only one adjustment plate. Operators can adjust the rotation or pitch of the same adjustment plate. Compared to designs using two adjustment plates in related technologies, firstly, this simplifies the structure, reduces the number of parts, and lowers costs; secondly, the structure is more compact, reducing space requirements and making it suitable for confined spaces, thus broadening its applicability.

[0010] In some technical solutions, the adjusting shaft may optionally include a first part and a second part connected together; the fixing plate is provided with a mounting hole, the first part passes through the mounting hole, and the first part is threadedly connected to the mounting hole; the adjusting plate is provided with a mounting groove on the side facing the fixing plate, at least a portion of the first part is provided in the mounting groove, and the first part is ball-jointed with the mounting groove.

[0011] In this technical solution, by setting an adjustment shaft, firstly, the first part is threadedly engaged with the mounting hole, which can precisely control the axial feed of the adjustment shaft and realize the quantitative adjustment of the distance between the adjustment plate and the fixed plate; secondly, the second part forms a ball joint structure with the mounting groove, so that when the distance between the adjustment plate and the fixed plate is not zero, the adjustment plate can be adjusted in multiple angles such as pitch and rotation, breaking through the single degree of freedom limitation of the traditional fixed shaft structure and providing a more flexible attitude adjustment space for the flat panel detector.

[0012] In some technical solutions, the first part can optionally be a hemisphere, and the shape of the mounting groove can be adapted to the shape of the first part.

[0013] In this technical solution, the first part and the mounting groove cooperate to form a stable spherical rotating pair. The operator can rotate the adjustment plate around the center of the hemisphere in multiple directions and at multiple angles to achieve rotational or pitch adjustment.

[0014] In some technical solutions, optionally, the end of the first part away from the second part is provided with an internal hexagonal hole.

[0015] In this technical solution, workers can use a hex wrench to rotate the adjusting shaft through the internal hexagonal hole, thereby precisely controlling the axial feed of the adjusting shaft and realizing the quantitative adjustment of the distance between the adjusting plate and the fixed plate.

[0016] In some technical solutions, optionally, the attitude adjustment component includes: a rotation adjustment component, which passes through the fixed plate and is threadedly connected to the fixed plate; the rotation adjustment component is used to abut against the adjustment plate and to drive the adjustment plate to rotate relative to the fixed plate around the axis of the adjustment shaft for attitude adjustment; and a pitch adjustment component, which passes through the fixed plate and is threadedly connected to the fixed plate and is used to abut against the adjustment plate; when the distance between the adjustment plate and the fixed plate is not zero, the pitch adjustment component is used to drive the adjustment plate to pitch relative to the fixed plate for attitude adjustment.

[0017] In this technical solution, by setting up rotation adjustment components and pitch adjustment components, the operator can adjust the attitude of the adjustment plate and the flat panel detector, and can achieve stepless adjustment, which is beneficial to improving the accuracy of attitude adjustment.

[0018] In some technical solutions, optionally, the fixing plate protrudes outward on the side facing the adjusting plate to form a frame structure; the adjusting plate is located inside the frame structure; the rotating adjusting component passes through the frame structure, and the rotating adjusting component is threadedly connected to the frame structure.

[0019] In this technical solution, the frame structure, relative to the rotating adjustment component, mainly serves as a mounting carrier. This design ensures that during the rotation of the adjustment component, one end of the component pushes the adjustment plate to rotate around the axis of the adjustment shaft, which helps improve the stability of the rotation process.

[0020] In some technical solutions, the rotating adjustment component may optionally be installed at the corner of the fixed plate.

[0021] In this technical solution, by optimizing the spatial layout, it is beneficial to avoid motion interference and increase the lever arm, so that the process of adjusting the rotation posture of the adjustment plate by rotating the adjustment component is more labor-saving.

[0022] In some technical solutions, optionally, the adjusting plate is provided with a connecting hole; the fixed plate is provided with an arc-shaped groove; one end of the position locking member is provided with a first end cap, and the other end of the position locking member passes through the arc-shaped groove and the connecting hole; when the first end cap is in contact with the fixed plate, the adjusting plate and the fixed plate are relatively fixed; when the first end cap is not in contact with the fixed plate, the adjusting plate can rotate relative to the fixed plate.

[0023] In this technical solution, when the first end cap is in contact with the fixed plate, the position locking component is in a tightened state, and the adjusting plate is relatively fixed to the fixed plate. When the first end cap is not in contact with the fixed plate, the position locking component is in a loosened state, and the adjusting plate can rotate relative to the fixed plate. Operators can tighten or loosen the position locking component by rotating it, thereby locking or unlocking the adjusting plate. The operation is simple, convenient, and quick.

[0024] In some technical solutions, optionally, during the process of the adjusting plate rotating relative to the fixed plate around the axis of the adjusting shaft, the position locking element moves within the arc-shaped groove.

[0025] In this technical solution, by setting an arc groove, the adjusting plate can make way for the fixed plate during its rotation, thus avoiding motion interference; it can also guide the rotation process to a certain extent.

[0026] The second aspect of this utility model provides an industrial CT device, comprising: a flat panel detector adjustment mechanism as described in any of the above technical solutions; a flat panel detector disposed on an adjustment plate of the flat panel detector adjustment mechanism; and an X-ray source for emitting X-rays to the flat panel detector to enable the flat panel detector to form an image.

[0027] Since industrial CT equipment includes the flat panel detector adjustment mechanism of any of the above technical solutions, it has the beneficial effects of any of the above technical solutions, which will not be elaborated here.

[0028] Additional aspects and advantages of the present invention will become apparent in the following description or may be learned by practice of the present invention. Attached Figure Description

Detailed Implementation

[0035] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, embodiments of the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] Industrial Computed Tomography (ICT) equipment is a core precision testing device in the fields of industrial non-destructive testing, quality control, and reverse engineering. Based on the principle of ionizing radiation penetration imaging, ICT equipment uses a radiation source (such as an X-ray tube or gamma-ray source) to emit ionizing rays. After the rays penetrate the workpiece, their intensity decreases due to differences in material, density, and thickness at different parts of the workpiece. A flat panel detector then collects the attenuated ray signal. Finally, a computer system performs data reconstruction, noise reduction, and analysis on the collected signal to generate a three-dimensional tomographic image or model that clearly shows internal defects (such as porosity, cracks, and shrinkage cavities), assembly relationships, and key dimensions of the workpiece. This enables non-destructive testing, quality assessment, and reverse modeling of industrial products.

[0038] In industrial CT equipment using related technologies, flat panel detectors mostly employ a fixed installation structure, with their installation position and spatial orientation remaining constant and unadjustable. Because the orientation of the flat panel detector cannot be adjusted, operators cannot tailor the detector's angle and position according to the specific characteristics of the workpiece being inspected, actual imaging requirements, or the placement of the X-ray source. This leads to problems such as uneven signal reception and misalignment of the effective detection area during X-ray signal acquisition, making it difficult to optimize imaging results. Insufficient imaging quality may even result in missed detection of minute internal defects in the workpiece or increased dimensional measurement errors, affecting detection accuracy.

[0039] This utility model aims to provide a flat panel detector adjustment mechanism and an industrial CT device. By adjusting the rotating shaft, the attitude adjustment component, and the position locking component in coordination, the operator can adjust the rotation or pitch of the adjustment plate to adjust the attitude (including position and angle) of the flat panel detector. This is convenient and quick, and helps to improve the imaging quality of the industrial CT device, thereby improving the detection accuracy.

[0040] In related technologies, the adjustment mechanism of a flat panel detector includes two adjustment plates, one for rotational adjustment and the other for pitch adjustment. The limitations of this design are that it occupies a relatively large space, is costly, and is unsuitable for confined spaces.

[0041] In this invention, the adjustment plate is connected to the fixed plate via an adjustment shaft, and there is only one adjustment plate. Operators can adjust the rotation or pitch of the same adjustment plate. Compared to related technologies that use two adjustment plates (one for rotation and the other for pitch), firstly, this design simplifies the structure, reduces the number of parts, and lowers costs; secondly, the structure is more compact, reducing space requirements and making it suitable for confined spaces, thus broadening its applicability.

[0042] The following reference Figures 1 to 4 This invention describes a flat panel detector adjustment mechanism and an industrial CT device according to some embodiments of the present invention.

[0043] In one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the flat panel detector adjustment mechanism 1 includes a fixed plate 10, an adjustment plate 12, an adjustment shaft 14, an attitude adjustment component 16, and a position locking component 18.

[0044] The adjusting plate 12 is used to connect the flat panel detector 20. One end of the adjusting shaft 14 passes through the fixed plate 10, and the adjusting shaft 14 and the fixed plate 10 are connected by a thread; the other end of the adjusting shaft 14 is connected to the adjusting plate 12 by a ball joint. The adjusting shaft 14 is used to adjust the distance between the adjusting plate 12 and the fixed plate 10.

[0045] The attitude adjustment component 16 is threaded through the fixed plate 10 and is used to abut against the adjustment plate 12. The attitude adjustment component 16 is used to adjust the attitude of the adjustment plate 12.

[0046] The position locking member 18 passes through the fixed plate 10 and the adjusting plate 12, and is used to lock the position of the adjusting plate 12.

[0047] The fixing plate 10 and the adjusting plate 12 mainly serve as mounting carriers for the flat panel detector 20. Operators can adjust the position and orientation of the flat panel detector 20 by changing the position and orientation of the adjusting plate 12.

[0048] The adjusting plate 12 is connected to the fixed plate 10 via the adjusting shaft 14. The operator can change the distance between the adjusting plate 12 and the fixed plate 10 by rotating the adjusting shaft 14. Since the adjusting shaft 14 and the adjusting plate 12 are ball-jointed, when the surface of the adjusting plate 12 is in contact with the surface of the fixed plate 10 (the distance between the adjusting plate 12 and the fixed plate 10 is zero) and the position locking member 18 is loosened, the operator can adjust the rotational attitude of the adjusting plate 12 using the attitude adjusting member 16. When the surface of the adjusting plate 12 is not in contact with the surface of the fixed plate 10 (the distance between the adjusting plate 12 and the fixed plate 10 is not zero) and the position locking member 18 is loosened, the operator can adjust the rotational attitude of the adjusting plate 12 using the attitude adjusting member 16, and can also adjust the pitch attitude of the adjusting plate 12 using the attitude adjusting member 16.

[0049] It should be noted that one end of the position locking member 18 is provided with a first end cap 182, and the other end of the position locking member 18 passes through the fixed plate 10 and the adjusting plate 12. When the first end cap 182 is in contact with the fixed plate 10, the position locking member 18 is in a tightened state, and the adjusting plate 12 is relatively fixed to the fixed plate 10; when the first end cap 182 is not in contact with the fixed plate 10, the position locking member 18 is in a loosened state, and the adjusting plate 12 can rotate relative to the fixed plate 10.

[0050] This utility model aims to provide a flat panel detector adjustment mechanism 1. By adjusting the rotation shaft 14, the attitude adjustment component 16 and the position locking component 18 in cooperation, the operator can adjust the rotation attitude or pitch attitude of the adjustment plate 12 to adjust the attitude (including position and angle) of the flat panel detector 20. This is convenient and quick, and helps to improve the imaging quality of the industrial CT equipment 2, thereby improving the detection accuracy.

[0051] It should be noted that the adjustment plate 12 is connected to the fixed plate 10 via the adjustment shaft 14, and there is only one adjustment plate 12. Operators can adjust the rotation or pitch of the same adjustment plate 12. Compared to the design of using two adjustment plates 12 in related technologies, firstly, it simplifies the structure, reduces the number of parts, and lowers costs; secondly, the structure is more compact, reducing space occupation and making it suitable for confined spaces, thus broadening its applicability.

[0052] The advantages of the flat panel detector adjustment mechanism 1 of this utility model are:

[0053] Firstly, it has a compact structure and a simple principle. Secondly, it is suitable for places with limited space and has good adjustability. Thirdly, the distance between the flat panel detector 20 and the X-ray source 22 can be adjusted by adjusting the rotating shaft 14, which increases the versatility of the imaging effect. Fourthly, by reducing one plate (compared to the design method of setting two adjustment plates in related technologies, one adjustment plate 12 is reduced) to achieve the same adjustment requirements, it is beneficial to reduce processing costs. Fifthly, by adjusting the cooperation of the rotating shaft 14, the attitude adjustment component 16 and the position locking component 18, the attitude adjustment of the flat panel detector 20 is more convenient and faster, and stepless adjustment can be achieved.

[0054] It should be emphasized that the adjustment plate 12 is connected to the fixed plate 10 via the adjustment shaft 14. The number of adjustment plates 12 is singular, which helps reduce the number of parts, improves space utilization, and also reduces costs and increases efficiency, achieving the same requirements with less structural cost. The flat panel detector adjustment mechanism 1 of this invention fully considers ergonomics, which helps reduce the difficulty for users to adjust the posture of the flat panel detector 20. Furthermore, the flat panel detector adjustment mechanism 1 of this invention can perform small-distance adjustments to the FDD (Flat Detector Distance, the distance between the flat panel detector 20 and the X-ray source 22), which helps improve imaging effects.

[0055] In one specific embodiment, the number of fixed plates 10 is one, and the number of adjusting plates 12 is one.

[0056] In one specific embodiment, the position locking element 18 is a locking screw.

[0057] In some embodiments, the number of position locking elements 18 may be at least one, that is, there may be one or more position locking elements 18. Taking into account the locking effect on the position of the adjustment plate 12, the space occupied, the cost and other factors, the position locking elements 18 are flexibly set according to actual needs.

[0058] Alternatively, when there are multiple position locking elements 18, the multiple position locking elements 18 are arranged in a circumferential array.

[0059] Optionally, when there are multiple position locking elements 18, the multiple position locking elements 18 are located on different arcs, and the multiple arcs are arranged with the same center.

[0060] In one specific embodiment, the number of position locking elements 18 is five. Of the five position locking elements 18, two are located on a first arc, and the other two are located on a second arc. The center of the circle opposite the first arc is the same as the center of the circle opposite the second arc.

[0061] This design has two advantages. First, when the posture of the adjustment plate 12 needs to be adjusted, all five position locking parts 18 can be loosened. Since the first and second arcs are set to be concentric, it helps to avoid motion interference. Second, when the position of the adjustment plate 12 needs to be locked, it helps to improve the locking effect.

[0062] In some embodiments, optionally, such as Figure 2 As shown, the adjusting shaft 14 includes a first part 142 and a second part 144 connected together. The fixing plate 10 has a mounting hole 102, through which the first part 142 passes, and the first part 142 is threadedly connected to the mounting hole 102. The adjusting plate 12 has a mounting groove 122 on the side facing the fixing plate 10, and at least a portion of the second part 144 is disposed within the mounting groove 122, with the second part 144 and the mounting groove 122 being ball-jointed.

[0063] Optionally, the first part 142 and the second part 144 are fixedly connected by welding or bonding, which is simple, convenient and quick to process.

[0064] Optionally, the first part 142 and the second part 144 are integrated into one piece, which has better mechanical properties and higher connection strength compared to post-processing, and helps to reduce the number of parts and improve assembly efficiency.

[0065] The outer wall of the first part 142 is provided with external threads, and the inner wall of the mounting hole 102 is provided with internal threads. The first part 142 and the mounting hole 102 are threadedly engaged.

[0066] The adjusting plate 12 has a recessed mounting groove 122 on the side facing the fixing plate 10. The shape of the mounting groove 122 is adapted to the shape of the second part 144, and the second part 144 and the mounting groove 122 are ball-jointed. The second part 144 can rotate at multiple angles relative to the mounting groove 122 in three-dimensional space.

[0067] When the surface of the adjusting plate 12 abuts against the surface of the fixed plate 10 (the distance between the adjusting plate 12 and the fixed plate 10 is zero) and the position locking member 18 is in the loosened state, the operator can adjust the rotational attitude of the adjusting plate 12 through the attitude adjustment member 16. When the surface of the adjusting plate 12 does not abut against the surface of the fixed plate 10 (the distance between the adjusting plate 12 and the fixed plate 10 is not zero) and the position locking member 18 is in the loosened state, the operator can adjust the rotational attitude of the adjusting plate 12 through the attitude adjustment member 16, and can also adjust the pitch attitude of the adjusting plate 12 through the attitude adjustment member 16.

[0068] By setting the adjustment shaft 14, firstly, the threaded engagement between the first part 142 and the mounting hole 102 allows for precise control of the axial feed of the adjustment shaft 14, enabling quantitative adjustment of the distance between the adjustment plate 12 and the fixed plate 10; secondly, the ball joint structure between the second part 144 and the mounting groove 122 allows for multi-angle pitch, rotation, and other attitude adjustments of the adjustment plate 12 when the distance between the adjustment plate 12 and the fixed plate 10 is non-zero, breaking through the single degree of freedom limitation of the traditional fixed shaft structure and providing a more flexible attitude adjustment space for the flat panel detector 20.

[0069] In some embodiments, the mounting groove 122 may optionally be provided with a self-lubricating layer. The self-lubricating layer is made of polytetrafluoroethylene. By providing a self-lubricating layer, frictional resistance during relative rotation can be reduced, while avoiding a decrease in precision caused by wear of the mating surfaces.

[0070] In some embodiments, the first part 142 is optionally a hemisphere, and the shape of the mounting groove 122 is adapted to the shape of the first part 142.

[0071] Through the cooperation of the first part 142 and the mounting groove 122, a stable spherical rotating pair is formed. The operator can rotate the adjustment plate 12 around the center of the hemisphere in multiple directions and at multiple angles to achieve rotational or pitch attitude adjustment.

[0072] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the end of the first part 142 away from the second part 144 is provided with an internal hexagonal hole 1422.

[0073] The internal hexagonal hole 1422 is used to accommodate a hexagonal wrench. The operator can use the hexagonal wrench to rotate the adjusting shaft 14 through the internal hexagonal hole 1422, thereby precisely controlling the axial feed of the adjusting shaft 14 and realizing the quantitative adjustment of the distance between the adjusting plate 12 and the fixed plate 10.

[0074] The distance between the flat panel detector 20 and the X-ray source 22 can be adjusted by adjusting the rotating shaft 14, which increases the versatility of the imaging effect.

[0075] In some embodiments, optionally, such as Figure 1 , Figure 2 and Figure 3 As shown, the attitude adjustment component 16 includes a rotation adjustment component 162 and a pitch adjustment component 164.

[0076] The rotating adjustment component 162 is inserted through the fixed plate 10 and is threadedly connected to the fixed plate 10. The rotating adjustment component 162 is used to abut against the adjustment plate 12 and to drive the adjustment plate 12 to rotate relative to the fixed plate 10 around the axis of the adjustment shaft 14 for attitude adjustment.

[0077] The pitch adjustment component 164 is threaded through the fixed plate 10 and is used to abut against the adjustment plate 12. When the distance between the adjustment plate 12 and the fixed plate 10 is not zero, the pitch adjustment component 164 is used to drive the adjustment plate 12 to adjust its pitch attitude relative to the fixed plate 10.

[0078] Optionally, the fixing plate 10 is provided with a first screw hole, and the wall of the first screw hole is provided with internal threads. The outer wall of the rotary adjustment component 162 is provided with external threads. Therefore, the rotary adjustment component 162 and the first screw hole are threadedly fitted.

[0079] When it is necessary to adjust the rotational attitude of the adjustment plate 12, first loosen the position locking member 18 (the position locking member 18 is in the loosened state), and then drive the adjustment plate 12 to rotate relative to the fixed plate 10 around the axis of the adjustment shaft 14 by rotating the rotation adjustment member 162.

[0080] By setting the rotating adjustment component 162, the operator can adjust the attitude of the adjustment plate 12 and the flat panel detector 20, and can achieve stepless adjustment, which is beneficial to improving the accuracy of attitude adjustment.

[0081] It should be noted that the number of rotating adjustment components 162 is at least one, that is, there can be one or more rotating adjustment components 162. Considering the effect of adjusting the rotational attitude of the adjustment plate 12, the space occupied, the cost and other factors, the rotating adjustment components 162 can be flexibly set according to actual needs.

[0082] In one specific embodiment, the number of rotation adjustment members 162 is two.

[0083] In one specific embodiment, the rotating adjustment element 162 is a rotating adjustment screw.

[0084] Optionally, the fixing plate 10 is provided with a second screw hole, and the wall of the second screw hole is provided with internal threads. The outer wall of the pitch adjustment component 164 is provided with external threads. Therefore, the pitch adjustment component 164 and the second screw hole are threadedly fitted.

[0085] When it is necessary to adjust the pitch attitude of the adjustment plate 12, first loosen the position locking piece 18, and lift the adjustment plate 12 a certain distance by rotating the adjustment shaft 14 (the distance between the adjustment plate 12 and the fixed plate 10 is not zero). Then, by rotating the pitch adjustment piece 164, the adjustment plate 12 is driven to adjust the pitch attitude relative to the fixed plate 10 around the axis of the adjustment shaft 14.

[0086] By setting the pitch adjustment component 164, the staff can adjust the attitude of the adjustment plate 12 and the flat panel detector 20, and can achieve stepless adjustment, which is beneficial to improving the accuracy of attitude adjustment.

[0087] It should be noted that the number of pitch adjustment components 164 is at least one; that is, there can be one or more pitch adjustment components 164. Considering the effect of pitch attitude adjustment on the adjustment plate 12, the space occupied, the cost, and other factors, the pitch adjustment components 164 can be flexibly set according to actual needs. In addition, the distance between the adjustment plate 12 and the fixed plate 10 is non-zero, indicating that the surface of the adjustment plate 12 does not abut or contact the surface of the fixed plate 10.

[0088] In one specific embodiment, there are four pitch adjustment elements 164. The four pitch adjustment elements 164 are respectively located at the four corners near the adjustment plate 12.

[0089] In one specific embodiment, the pitch adjustment element 164 is a pitch adjustment screw.

[0090] In some embodiments, the flat panel detector 20 is optionally mounted on the adjustment plate 12. The adjustment plate 12 and the fixing plate 10 are circumferentially locked together by five locking screws. Initially, the adjustment plate 12 and the fixing plate 10 can be installed without gaps, and in this state, the adjustment shaft 14 is at its lowest position.

[0091] When it is necessary to adjust the rotational attitude of the adjustment plate 12, first loosen the locking screw, and then adjust the rotational attitude by rotating the two adjustment screws.

[0092] When the pitch attitude of the adjustment plate 12 needs to be adjusted, first loosen the locking screws, and then rotate the adjustment shaft 14 with an Allen wrench (for example, rotate the adjustment shaft 14 clockwise to move the adjustment shaft 14 axially by about 2mm). At this time, there is a certain gap between the adjustment plate 12 and the fixed plate 10 (for example, the gap is 2mm). Then, the pitch attitude is adjusted by using the four pitch adjustment screws. At the same time, the rotation attitude can also be adjusted by using the two rotation adjustment screws.

[0093] In some embodiments, optionally, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixing plate 10 protrudes outward from the side facing the adjusting plate 12 to form a frame structure 104. The adjusting plate 12 is disposed within the frame structure 104. The rotating adjusting member 162 passes through the frame structure 104, and the rotating adjusting member 162 is threadedly connected to the frame structure 104.

[0094] It should be noted that the frame structure 104 and the fixing plate 10 are an integral structure. Compared with the post-processing method, it has better mechanical properties and higher connection strength, which helps to reduce the number of parts and improve assembly efficiency.

[0095] In addition, there is a gap between the adjustment plate 12 and the edge of the frame structure 104 to ensure that no motion interference occurs when the operator adjusts the rotational posture of the adjustment plate 12.

[0096] By rotating the rotating adjustment component 162, the operator can drive the adjustment plate 12 to rotate relative to the fixed plate 10 around the axis of the adjustment shaft 14. The frame structure 104, relative to the rotating adjustment component 162, mainly serves as a mounting carrier. This design ensures that during the rotation of the rotating adjustment component 162, one end of the component pushes the adjustment plate 12 to rotate around the axis of the adjustment shaft 14, thus improving the stability of the rotation process.

[0097] In some embodiments, the frame structure 104 may optionally be provided with weight-reduction holes. By providing weight-reduction holes, weight reduction and material saving can be achieved.

[0098] In some embodiments, optionally, such as Figure 1 As shown, the rotating adjustment member 162 is inserted at the corner of the fixed plate 10.

[0099] Optimizing the spatial layout helps avoid motion interference and increases the lever arm, making it easier for workers to adjust the rotational posture of the adjustment plate 12 using the rotating adjustment component 162.

[0100] In one specific embodiment, there are two rotating adjustment members 162. The two rotating adjustment members 162 are respectively located at two corner positions on the same side wall of the adjustment plate 12. This design allows the rotating adjustment members 162 to exert a more balanced thrust on the adjustment plate 12, which helps to improve the smoothness of the adjustment process.

[0101] In some embodiments, optionally, such as Figure 3 As shown, the adjustment plate 12 is provided with a connection hole 124, and the fixing plate 10 is provided with an arc groove 106.

[0102] One end of the position locking member 18 is provided with a first end cap 182, and the other end of the position locking member 18 passes through the arc groove 106 and the connecting hole 124.

[0103] When the first end cap 182 is in contact with the fixed plate 10, the adjusting plate 12 is fixed relative to the fixed plate 10; when the first end cap 182 is not in contact with the fixed plate 10, the adjusting plate 12 can rotate relative to the fixed plate 10.

[0104] When the first end cap 182 is in contact with the fixed plate 10, the position locking member 18 is in a tightened state, and the adjusting plate 12 is relatively fixed to the fixed plate 10. When the first end cap 182 is not in contact with the fixed plate 10, the position locking member 18 is in a loosened state, and the adjusting plate 12 can rotate relative to the fixed plate 10. The operator can tighten or loosen the position of the adjusting plate 12 by rotating the position locking member 18, which is simple, convenient and quick to operate.

[0105] It should be noted that even when the position locking member 18 is in the loosened state, a portion of the structure within the position locking member 18 is still in a threaded engagement with the connecting hole 124, only the first end cap 182 does not contact the fixing plate 10. Therefore, the position locking member 18 will not lock the position of the adjusting plate 12 at this time.

[0106] In some embodiments, optionally, during the rotation of the adjusting plate 12 relative to the fixed plate 10 about the axis of the adjusting shaft 14, the position locking member 18 moves within the arcuate groove 106.

[0107] By setting the arc groove 106, it can make way for the adjustment plate 12 during the rotation of the fixed plate 10, thus avoiding motion interference; it can also guide the rotation process to a certain extent.

[0108] In one embodiment of this utility model, such as Figure 4As shown, the industrial CT equipment 2 includes a flat panel detector adjustment mechanism 1, a flat panel detector 20, and a radiation source 22 as described in any of the above embodiments. The flat panel detector 20 is mounted on an adjustment plate 12 of the flat panel detector adjustment mechanism 1. Operators can adjust the position and orientation of the flat panel detector 20 by changing the position and orientation of the adjustment plate 12.

[0109] The X-ray source 22 is used to emit X-rays to the flat panel detector 20 so that the flat panel detector 20 can form an image.

[0110] Optionally, the radiation source 22 is an X-ray tube or a gamma-ray source.

[0111] The industrial CT equipment 2 is based on the principle of ionizing radiation penetration imaging. The X-ray source 22 emits X-rays. After the X-rays penetrate the workpiece to be inspected, their intensity is attenuated according to the material, density and thickness of different parts of the workpiece. The attenuated X-ray signal is then collected by the flat panel detector 20. Finally, the computer system performs data reconstruction, noise reduction and analysis on the collected signal to generate a three-dimensional tomographic image or stereo model.

[0112] Since the industrial CT equipment 2 includes the flat panel detector adjustment mechanism 1 in any of the above embodiments, it has the beneficial effects of any of the above embodiments, which will not be repeated here.
