Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of workpiece welding detection, and in particular relates to a groove ray detection alignment device. Background Art
[0002] Heavy chemical machinery and equipment often require the detection of dissimilar steel isolation layers. After the isolation layer is welded, the welded parts need to be inspected, mainly to detect the lack of fusion defects, and the strength of the welding can be judged by the lack of fusion defect detection.
[0003] At present, the lack of fusion defect detection mainly adopts X-ray machine detection. Specifically, during the detection process, the X-ray machine is positioned so that the emitted rays should extend along the bevel direction to achieve the best detection effect. That is, by ensuring that the emitted rays extend along the bevel direction, the welding parts can be detected in all directions, and the side parts will not be missed (i.e. the detection is incomplete).
[0004] During the inspection process, the positioning of the X-ray machine can only be done manually, and there is no special device for verification. Therefore, in actual work, there is no particularly effective positioning method for the non-destructive testing of X-ray machines for X-ray flaw detection of heterogeneous steel isolation layers, and there is no mature tool to solve this problem.
[0005] At present, during the inspection process, the operator can only perform visual calibration, that is, during the inspection process, the operator's line of sight is used to determine whether the X-ray machine's rays are along the direction of the slope. However, this inspection method has very large errors or even mistakes due to different factors such as the operator's experience and vision.
[0006] Therefore, there are many uncontrollable factors, resulting in low detection accuracy. In addition, the position of the X-ray machine needs to be adjusted continuously based on the operator's line of sight, which also causes the detection time to be too long and the detection operation to be too complicated. Therefore, the detection efficiency is very low. Utility Model Content

[0042] Example 1
[0043] like Figure 1-5 As shown, a groove ray detection alignment device includes an adjustment frame mechanism, and both ends of the adjustment frame mechanism are respectively hinged with a detection adjustment plate mechanism 1.
[0044] The detection plate mechanism is used to correct the position of the ray base.
[0045] Specifically, the detection adjustment plate mechanism 1 includes an outer arc angle adjustment plate 11 and an inner arc angle adjustment plate 12 hinged in the outer arc angle adjustment plate 11 (the inner arc angle adjustment plate 12 and the outer arc angle adjustment plate 11 have transverse cross-sectional shapes that are both semicircular, and are made of stainless steel or plastic). According to the existing conventional method, angle markings A are provided on the tops of the inner arc angle adjustment plate 12 and the outer arc angle adjustment plate 11.
[0046] Specifically, the outer arc angle adjustment plate 11 and the inner arc angle adjustment plate 12 are hinged in the following manner:
[0047] An arc-shaped hinge port is provided on the outer arc-shaped angle adjustment plate 11, and the inner arc-shaped angle adjustment plate 12 is hinged in the arc-shaped hinge port (specifically, both ends of the inner arc-shaped angle adjustment plate 12 are respectively fixedly connected with hinge shafts B, and the hinge shafts B are hinged on the side walls of the arc-shaped hinge port).
[0048] At the same time, in order to keep the top surfaces of the outer arc angle adjustment plate 11 and the inner arc angle adjustment plate 12 flush, when the inner arc angle adjustment plate 12 needs to be used, several adjustment supports installed at the bottom of the outer arc angle adjustment plate 11 are adjusted. After adjustment, the outer arc angle adjustment plate 11 is flipped to the lower position without affecting the transmission of rays.
[0049] Specifically, the bottom of the outer arc angle adjustment plate 11 is supported on the bottom of the inner arc angle adjustment plate 12 by a plurality of adjustment supports. The adjustment supports are rotated until the adjustment supports lose their supporting function, and the outer arc angle adjustment plate 11 flips down to a vertical state.
[0050] The specific structure of the adjusting support is as follows:
[0051] The adjustment support member includes an adjustment screw fixedly connected to the bottom of the outer arc angle adjustment plate 11, and a T-shaped support handle 111 is threadedly connected to the adjustment screw; the support is adjusted by rotating the T-shaped support handle 111. Specifically, when the T-shaped support handle 111 is rotated until the extended portion of the T-shaped support handle 111 is no longer supported on the bottom of the inner arc angle adjustment plate 12, the outer arc angle adjustment plate 11 in the unsupported state automatically flips to a vertical state.
[0052] Specifically, during use, the outer arc angle adjustment plate 11 or the inner arc angle adjustment plate 12 is selected according to the size of the welding workpiece. For example, when detecting a small workpiece, the inner arc angle adjustment plate 12 can be used to more accurately reference the workpiece. Conversely, for a large workpiece, the large outer arc angle adjustment plate 11 can be used to more accurately reference.
[0053] The specific measurement method is:
[0054] In actual use, adjust the outer arc angle adjustment plate 11 or the inner arc angle adjustment plate 12 on the workpiece surface according to the angle of the groove drawing to be consistent with the drawing, and adjust the outer arc angle adjustment plate 11 or the inner arc angle adjustment plate 12 on the other end (adjust by rotating) and place it on the window plane of the X-ray machine. After adjusting in the above manner, adjust the X-ray machine so that the X-ray machine beam is at the 90-degree position of the scale mark.
[0055] At this time, the X-ray machine's beam can perfectly penetrate along the groove direction. In this way, it is possible to accurately find that the beam emitted by the X-ray machine passes through the isolation layer weld in parallel, and on this basis, the X-ray detection of the groove can achieve the best effect.
[0056] During use, the outer arc angle adjustment plate 11 or the inner arc angle adjustment plate 12 is selected according to the above method.
[0057] Example 2
[0058] like Figure 1-5 As shown, based on the structure of Example 1, in order to adjust the position of the detection adjustment plate mechanism 1 on both sides during use, the adjustment frame mechanism includes a horizontal adjustment rod assembly. Specifically, the horizontal adjustment rod assembly includes a central fixed rod 22, and the two ends of the central fixed rod 22 are sleeved with an adjustment sleeve rod 21, and the adjustment sleeve rod 21 is hingedly connected to the bottom position of the inner arc angle adjustment plate 12 (the adjustment sleeve rod 21 is hingedly connected to the bottom position of the inner arc angle adjustment plate 12 through a pin shaft).
[0059] Specifically, the horizontal adjustment rod assembly also includes an adjustment sleeve rod 21, which has a sleeve cavity slidably connected to the central fixed rod 22; the bottom of the adjustment sleeve rod 21 is threaded upwardly with a first adjustment screw 211 that is fastened to the central fixed rod 22.
[0060] Loosen the first adjusting screw 211 and adjust the detection adjustment plate mechanism 1 on both sides, so as to facilitate the length adjustment according to the workpiece or the X-ray machine and ensure that the detection adjustment plate mechanism 1 on the side can be located on the X-ray machine window.
[0061] Similarly, for longitudinal adjustment, the following structure is adopted:
[0062] The adjustment frame mechanism also includes a longitudinal adjustment component slidably connected to the center of the central fixed rod 22. The longitudinal adjustment component includes longitudinal adjustment rods 4 spaced apart on both sides (two corresponding through holes are provided in the center of the central fixed rod 22), and the longitudinal adjustment rod 4 is slidably connected to the central fixed rod 22. Similarly, the bottom of the central fixed rod 22 is threaded upwardly with a second adjustment screw 221 that abuts and presses against the longitudinal adjustment rod 4.
[0063] Loosen the second adjusting screw 221 to adjust the entire device longitudinally, ensuring that the detection adjustment plate mechanism 1 can be installed corresponding to the X-ray machine or the workpiece in the above manner.
[0064] Similarly, the ends of the longitudinal adjustment rod 4 are respectively connected by a height adjustment member. The height adjustment member includes a height adjustment plate 3 (the height adjustment plate 3 is L-shaped, the longitudinal adjustment rod 4 is assembled on the vertical plate portion of the height adjustment plate 3, and the integrally formed horizontal plate portion is installed on the workbench in the existing manner in actual use), the height adjustment plate 3 is provided with long adjustment openings spaced apart on both sides, and an inner vertical adjustment screw 31 is fixedly connected in the long adjustment opening; the inner vertical adjustment screw 31 is slidably connected to the longitudinal adjustment rod 4, and a pair of nuts 311 positioned on both sides of the longitudinal adjustment rod 4 are threadedly connected to the inner vertical adjustment screw 31.
[0065] Similarly, loosen the nut 311 and slide the height adjustment device to adjust the height position. After the adjustment, position the nut 311 on both sides of the longitudinal adjustment rod 4 again.
[0066] This type of adjustment frame mechanism can be adjusted in multiple directions, and thus in the actual detection process, it can cope with the complex geographical environment of the workshop and ensure that the detection adjustment plate mechanism 1 can be matched to the X-ray machine or the workpiece in the above manner.
[0067] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
