Description

Technical Field

[0001] This utility model relates to the field of parts inspection technology, and in particular to an enhanced tooling for X-ray inspection of nozzle annular weld seams. Background Technology

[0002] like Figure 1 The nozzle shown has a bent pipe connected to its bottom end. A flange at a certain angle is installed between the bent pipe and the nozzle body, and several positioning holes are provided on the flange. During processing, the nozzle head is welded to the top of the nozzle, forming a ring-shaped weld at the top. To inspect the welding quality, X-ray inspection is required. During inspection, the weld must be horizontal. Because there is a structural obstruction inside the ring-shaped weld after the nozzle head is welded, each X-ray can only clearly detect the left and right sides of the obstruction structure; the front and back sides cannot be clearly detected. Therefore, the ring-shaped weld needs to be rotated 90 degrees to complete the inspection. Conventional inspection involves inspecting one item at a time on the X-ray inspection equipment's worktable. During inspection, the inspector rotates the nozzle 90 degrees by feel to inspect the other two sides. This rotation angle introduces errors, and the position after rotation also deviates, requiring readjustment of the imaging equipment's focus. This results in poor consistency of inspection results and low inspection efficiency. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide an enhanced tooling for X-ray inspection of nozzle circumferential welds. This tooling is simple in structure, easy to install, and accurately positioned, enabling simultaneous inspection of circumferential welds of multiple nozzles, which greatly improves inspection efficiency and provides excellent consistency of inspection results.

[0004] This utility model provides an enhanced tooling for X-ray inspection of nozzle-shaped weld seams, comprising:

[0005] The base has several slots evenly spaced along a straight line on its top surface;

[0006] The positioning seat has at least the same number as the groove, and its bottom end is embedded in the groove to position and support the nozzle so that its annular weld is located on a horizontal plane.

[0007] A positioning component is disposed between the groove and the positioning seat, and is used to position the positioning seat by embedding it into the groove at a preset angle and at an angle of 90 degrees rotation from the preset angle.

[0008] Furthermore, the base is elongated, and the grooves are evenly distributed along the length of the base.

[0009] Furthermore, several waist-shaped holes are symmetrically opened on both sides of the top surface of the base.

[0010] Furthermore, the positioning seat includes a base, the bottom of which is embedded in the groove, and a support seat is fixedly provided on the top of the base. The support seat is provided with a positioning inclined surface adapted to the inclination angle of the nozzle flange. An clearance groove for the nozzle bend to pass through is opened on the top of the positioning inclined surface on the support seat. Several positioning pins are fixedly provided on the positioning inclined surface outside the clearance groove, each of which is clearance-fitted with each positioning hole of the flange.

[0011] Furthermore, the positioning seat is integrally molded from polytetrafluoroethylene material.

[0012] Furthermore, the positioning component includes a positioning block fixedly disposed at the bottom of the groove. The positioning block is rectangular or square, and a positioning groove adapted to the positioning block is provided at the center of the bottom surface of the positioning seat.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0029] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Please refer to Figures 1-6 An embodiment of this utility model provides an enhanced tooling for X-ray inspection of nozzle annular welds, comprising:

[0031] The base 1 has several slots 11 evenly spaced on its top surface along a straight line;

[0032] The positioning seat 2 has at least the same number as the groove 11, and its bottom end is embedded in the groove 11 to position and support the nozzle 4 so that its annular weld is on the horizontal plane.

[0033] The positioning component 3 is disposed between the groove 11 and the positioning seat 2, and is used to position the positioning seat 2 by embedding it into the groove 11 at a preset angle and at an angle of 90 degrees rotation from the preset angle.

[0034] In this embodiment, when performing X-ray inspection on the annular weld of the nozzle 4, the base 1 is first fixedly installed on the worktable of the X-ray inspection equipment, so that the arrangement direction of each groove 11 is perpendicular to the inspection direction; then, the nozzle 4 to be inspected is positioned and installed on each positioning seat 2, so that the annular weld of the nozzle 4 is in a horizontal state; then, each positioning seat 2 is installed into each groove 11 on the base 1 one by one, and each positioning seat 2 is positioned by the positioning component 3, so that it is embedded into the corresponding groove 11 at a preset angle. At this time, the left and right sides of each annular weld are inspected by the X-ray inspection equipment.

[0035] Then, the positioning seat 2 is removed and rotated 90 degrees, and then reinstalled onto the base 1 using the positioning component 3. After the reinstallation of each base 1 is completed, X-ray inspection is performed on the other two sides of each annular weld. The efficiency-enhancing tooling of this application has a simple structure, is easy to install, and has accurate positioning, enabling simultaneous inspection of annular welds with multiple nozzles 4, greatly improving inspection efficiency and ensuring good consistency of inspection results.

[0036] Preferably, the number of positioning seats 2 is twice the number of slots 11. When a group of nozzles 4 is being tested, the inspector installs the nozzle 4 to be tested on a spare positioning seat 2. After the previous group of nozzles 4 has been tested, the positioning seat 2 is directly replaced, saving the installation time of the nozzles 4 and further improving the testing efficiency.

[0037] In a preferred embodiment, such as Figure 2 and Figure 4 As shown, the base 1 is long and narrow, and the slots 11 are evenly distributed along the length of the base 1. While satisfying the configuration of the slots 11, the volume of the base 1 is minimized, the tooling weight is reduced, and the cost is saved.

[0038] In a preferred embodiment, such as Figure 2 and Figure 4 As shown, several waist-shaped holes 12 are symmetrically opened on both sides of the top surface of the base 1 so that the base 1 can be fixedly installed on the worktable of the X-ray inspection equipment by bolts.

[0039] In a preferred embodiment, such as Figure 3 and Figure 5 As shown, the positioning seat 2 includes a base 21, the bottom of which is embedded in a groove 11. A support seat 22 is fixedly installed on the top of the base 21. The support seat 22 is provided with a positioning inclined surface 23 that matches the inclination angle of the flange 41 of the nozzle 4. A clearance groove 24 is provided on the support seat 22 at the top of the positioning inclined surface 23 for the bent tube 42 of the nozzle 4 to pass through. Several positioning pins 25 are fixedly installed on the positioning inclined surface 23 outside the clearance groove 24, which respectively fit with the positioning holes 43 of the flange 41.

[0040] In this embodiment, when installing the nozzle 4, its bent pipe 42 is embedded into the clearance groove 24, and then each positioning hole 43 is aligned with the positioning pin 25, so that the positioning pin 25 is inserted into the positioning hole 43, and the flange 41 falls on the positioning slope 23. The positioning pin 25 and the positioning slope 23 cooperate to achieve the positioning support of the nozzle 4, so that its annular weld is on the horizontal plane, ensuring the accuracy of X-ray detection.

[0041] In a preferred embodiment, such as Figure 3 and Figure 5 As shown, the positioning seat 2 is integrally molded from polytetrafluoroethylene material, which meets the positioning and support requirements of the nozzle 4 and avoids affecting the detection effect of X-rays.

[0042] In a preferred embodiment, such as Figures 3-5 As shown, the positioning component 3 includes a positioning block 31 fixedly disposed at the bottom of the groove 11. The positioning block 31 is rectangular or square, and a positioning groove 32 adapted to the positioning block 31 is provided at the center of the bottom surface of the positioning seat 2.

[0043] In this embodiment, when the bottom of the positioning seat 2 is embedded in the groove 11, the positioning block 31 is embedded in the positioning groove 32; when inspecting the other side of the circumferential weld, the positioning seat 2 is rotated 90 degrees and reinstalled, and the positioning block 31 is embedded in the positioning groove 32 again, ensuring that the positioning seat 2 rotates accurately by 90 degrees, thus ensuring the accuracy and consistency of X-ray inspection.
