However, since the position of the metal X-ray tube is not fixed during manual grinding, the fit strength of the grinder on the metal X-ray tube is very likely to change during the grinding process, resulting in an uneven surface after the weld is removed, which is easy to damage the original size of the metal X-ray tube, thereby affecting the disassembly of other parts inside the metal X-ray tube.

[0037] This embodiment provides a weld grinding auxiliary jig to solve the problem that the X-ray tube 1 cannot be fixed during the weld grinding process.

[0038] Specifically, Figures 1 to 4 As shown, the weld grinding auxiliary jig is used to support the X-ray tube 1, and divides the X-ray tube 1 into an anode segment 11 and a cathode segment 12 along the axial direction of the X-ray tube 1. The outer diameter of the anode segment 11 is smaller than the outer diameter of the cathode segment 12, and a target plate 13 is provided inside the cathode segment 12. The weld grinding auxiliary jig includes a supporting base plate 2, a limiting ring 3 and a supporting ring 4, wherein a first supporting area 21 and a second supporting area 22 are provided on the supporting base plate 2, the anode segment 11 can be placed upright in the first supporting area 21, and the cathode segment 12 can be placed upright in the second supporting area 22; the limiting ring 3 is spaced apart and connected to the supporting base plate 2, the limiting ring 3, the first supporting area 21 and the second supporting area 22 are coaxially arranged, and the limiting ring 3 can surround the outer periphery of the cathode segment 12; the supporting ring 4 is spaced apart and connected to the supporting base plate 2, the supporting ring 4 is located between the limiting ring 3 and the supporting base plate 2, the inner diameter of the supporting ring 4 is configured to be larger than the outer diameter of the anode segment 11, the outer diameter of the supporting ring 4 is configured to be smaller than the inner diameter of the cathode segment 12, and the target plate 13 can be placed on the side of the supporting ring 4 away from the supporting base plate 2.

[0039] When grinding the weld of the cathode segment 12, the anode segment 11 is passed through the limiting ring 3 and the support ring 4 and placed in parallel at the first support area 21, thereby supporting the X-ray tube 1. At the same time, the limiting ring 3 is used to radially limit the cathode segment 12 to prevent the X-ray tube 1 from tilting. When grinding the weld of the anode segment 11, the cathode segment 12 is passed through the limiting ring 3 and placed in parallel at the second support area 22 to support the X-ray tube 1. At the same time, the target plate 13 is placed on the side of the support ring 4 away from the support base plate 2, so that the support ring 4 supports the target plate 13, thereby achieving the effect of improving the support stability of the X-ray tube 1. In the process of grinding the weld, the position of the X-ray tube 1 can be maintained stable, thereby improving the stability of the fit of the grinder to the X-ray tube 1, thereby improving the flatness of the weld removal surface, so that the X-ray tube 1 can maintain its original size, and improve the integrity of other parts inside the X-ray tube 1 during the disassembly process.

[0040] It should be pointed out that the X-ray tube 1 mentioned in this embodiment is a common component in the art, and its specific detailed structure will not be repeated here.

[0041] like Figure 2 As shown, the X-ray tube 1 includes a cathode cover 14 and an anode fixed end. The cathode weld 15 generated during welding between the cathode cover 14 and the end opening of the cathode segment 12 is located at the connection between the cathode cover 14 and the end opening of the cathode segment 12. The cathode weld 15 is an annular structure centered on the axis of the X-ray tube 1.Figure 3 As shown, the anode fixed - end weld 16 generated during the welding process at the end - opening of the anode fixed - end and the anode section 11 is located at the connection between the end - opening of the anode section 11 and the anode fixed - end. The anode fixed - end weld 16 is an annular structure centered on the axis of the X - ray tube 1.

[0042] When removing the cathode weld 15, in this embodiment, the inner wall of the limit ring 3 is spaced from the side wall of the cathode section 12 to adapt to X - ray tubes 1 of different diameters. In other embodiments, the limit ring 3 is attached to the outer wall of the cathode section 12 to improve the effect of radially limiting the X - ray tube 1.

[0043] Further, as Figure 1 shown, the weld grinding auxiliary jig further includes a first support portion 31. The limit ring 3 is connected to the support base plate 2 through the first support portion 31, so that the limit ring 3 is fixed on the support base plate 2 under the support of the first support portion 31, playing a role in fixedly supporting the limit ring 3. As Figure 4 shown, the first support portion 31 and the support base plate 2 are connected by countersunk head screws 32. In this embodiment, as Figure 1 shown, the first support portion 31 is a cylindrical structure. In other embodiments, the first support portion 31 can also be a cuboid or a long strip - shaped structure.

[0044] Further, the number of the first support portions 31 is multiple. The multiple first support portions 31 are evenly distributed along the circumferential direction of the limit ring 3. The multiple first support portions 31 act together along the circumferential direction of the limit ring 3 to improve the stability of supporting the limit ring 3. In this embodiment, as Figure 1 shown, the number of the first support portions 31 is 4. In other embodiments, the number of the first support portions 31 can also be 3 or 5, etc.

[0045] Optionally, as Figure 1 shown, the weld grinding auxiliary jig further includes a second support portion 41. The support ring 4 is connected to the support base plate 2 through the second support portion 41, so that the support ring 4 is fixed on the support base plate 2 under the support of the second support portion 41, playing a role in fixedly supporting the support ring 4. As Figure 4 shown, the second support portion 41 and the support base plate 2 are connected by countersunk head screws 32. In this embodiment, as Figure 1 shown, the second support portion 41 is a cylindrical structure. In other embodiments, the second support portion 41 can also be a cuboid or a long strip - shaped structure.

[0046] Further, the number of the second support portions 41 is multiple. The multiple second support portions 41 are evenly distributed along the circumferential direction of the support ring 4. The multiple second support portions 41 act together along the circumferential direction of the support ring 4 to improve the stability of supporting the support ring 4. In this embodiment, as Figure 1As shown, the number of the second supporting parts 41 is four. In other embodiments, the number of the second supporting parts 41 can also be three, five or the like.

[0047] Further, the weld grinding auxiliary fixture further includes a rotating mechanism 5. The rotating mechanism 5 includes a fixed part 51 and a rotating part 52. The fixed part 51 is arranged on the first supporting area 21. The rotating part 52 is rotationally connected with the fixed part 51 with the axis of the first supporting area 21 as the rotation axis. The anode section 11 can be placed upright on the rotating part 52, so as to realize the rotation of the X-ray tube 1 relative to the weld grinding auxiliary fixture, so that during the process of grinding the cathode weld 15, the X-ray tube 1 can rotate, which is convenient for grinding the annular cathode weld 15. Moreover, the arrangement of the rotating mechanism 5 can also avoid the problem that the end of the anode section 11 rubs against the supporting bottom plate 2 during the rotation of the X-ray tube 1. In this embodiment, the rotating mechanism 5 is a thrust bearing. The above-mentioned fixed part 51 is the bearing stator of the thrust bearing, and the rotating part 52 is the bearing rotor of the thrust bearing. In this embodiment, the inner wall of the limiting ring 3 is arranged at an interval from the side wall of the cathode section 12. Therefore, when the X-ray tube 1 rotates, the friction between the inner wall of the limiting ring 3 and the side wall of the cathode section 12 can be avoided, and further, the X-ray tube 1 can rotate more smoothly and will not damage the side wall of the cathode section 12.

[0048] In other embodiments, the rotating mechanism 5 includes a support rod and a support plate. One end of the support rod is arranged on the first supporting area 21, and the other end of the support rod is rotationally connected with the support plate with the axis of the first supporting area 21 as the rotation axis. That is, the above-mentioned fixed part 51 is the support rod, and the rotating part 52 is the support plate.

[0049] Optionally, the support ring 4 is provided with a convex structure 42. The convex structure 42 is arranged along the circumferential direction of the support ring 4 and extends in the direction away from the support bottom plate 2. When the target disc 13 is placed on the support ring 4, the convex structure 42 can surround the outer periphery of the target disc 13, achieving the effect of radially limiting the target disc 13, preventing the X-ray tube 1 from having a radial displacement, and improving the stability of fixing the X-ray tube 1. The convex structure 42 is arranged in a fitting manner with the target disc 13 to improve the effect of limiting the target disc 13. In another embodiment, the convex structure 42 is arranged at an interval from the target disc 13 to adapt to different models of X-ray tubes 1, especially to adapt to target discs 13 with different diameters. When there is no fitting between the target disc 13 and the convex structure 42, a small gap is left between the target disc 13 and the convex structure 42. The range of the gap value is 0.1 mm to 5.0 mm. Therefore, the target disc 13 can move a small range along its radial direction, and this structural design can prevent the target disc 13 from having a large radial displacement.

[0050] In this embodiment, as Figure 1 shown, the convex structure 42 extends along the circumferential direction of the support ring 4 and is connected end to end to form a ring.

[0051] In other embodiments, the convex structure 42 includes a plurality of bumps, and the plurality of bumps are evenly distributed along the circumferential direction of the support ring 4.

[0052] This embodiment also provides a weld grinding device, which can improve the flatness of the surface of the weld removal, so that the X-ray tube 1 can maintain its original size, and further improve the integrity of other parts inside the X-ray tube 1 during the disassembly process.

[0053] Specifically, the weld grinding device includes a frame (not shown in the figure), a grinding mechanism 6 and the above-mentioned weld grinding auxiliary jig. The weld grinding auxiliary jig and the grinding mechanism 6 are both arranged on the frame. The grinding mechanism 6 is used to grind the weld of the X-ray tube 1 placed on the weld grinding auxiliary jig. The grinding mechanism 6 is arranged on the frame, which improves the fixing stability of the grinding mechanism 6. The weld grinding device adopts the above-mentioned weld grinding auxiliary jig. When grinding the weld of the cathode section 12, the anode section 11 of the X-ray tube 1 is placed upright at the first support area 21. When grinding the weld of the anode section 11, the cathode section 12 of the X-ray tube 1 is placed upright at the second support area 22, and the target disk 13 is placed on the side of the support ring 4 away from the support base plate 2. Thus, when grinding the cathode weld 15 and the anode fixed-end weld 16 of the X-ray tube 1, the X-ray tube 1 can be fixed, preventing the problem that the position of the X-ray tube 1 changes during the weld grinding process, and further improving the flatness of the surface of the weld removal, so that the X-ray tube 1 can maintain its original size, and further improving the integrity of other parts inside the X-ray tube 1 during the disassembly process.

[0054] Further, the grinding mechanism 6 includes a first support rod 61, a second support rod 62, a grinding member 63 and a fixed base 64. Among them, one end of the first support rod 61 is connected to the grinding member 63, the other end of the first support rod 61 is rotatably connected to one end of the second support rod 62, the other end of the second support rod 62 is rotatably connected to the fixed base 64, and the fixed base 64 is arranged on the frame. The second support rod 62 is a telescopic rod, so as to facilitate adjusting the position of the grinding member 63 to adapt to different models of X-ray tubes 1 and X-ray tubes 1 at different positions. Specifically, when grinding the cathode weld 15, the first support rod 61 and the grinding member 63 are extended to the same horizontal position as the cathode weld 15 by stretching the second support rod 62, and the grinding member 63 is fitted to the cathode weld 15 by rotating the first support rod 61; when grinding the anode fixed-end weld 16, the first support rod 61 and the grinding member 63 are extended to the same horizontal position as the anode fixed-end weld 16 by stretching the second support rod 62, and the grinding member 63 is fitted to the anode fixed-end weld 16 by rotating the first support rod 61. As Figures 5 to 6 shown, in this embodiment, the fixed base 64 is fixed to the bracket by screws. In other embodiments, the fixed base 64 is fixed to the bracket by magnetic attraction.

[0055] In this embodiment, the grinding member 63 is a knife sharpener. In other embodiments, the grinding member 63 may also be sandpaper, a grindstone, a grinding wheel, or the like.

[0056] Furthermore, the weld grinding device further includes a rotation driving mechanism 7. The rotation driving mechanism 7 is disposed on the frame. The rotation driving mechanism 7 is used to drive the X-ray tube 1 to rotate about its own axis. When grinding the weld, the operation of manually rotating the X-ray tube 1 is omitted. Moreover, disposing the rotation driving mechanism 7 on the frame can improve the fixing stability of the rotation driving mechanism 7, and further improve the stability of the driving force magnitude applied by the rotation driving mechanism 7 to the X-ray tube 1.

[0057] Even further, the rotation driving mechanism 7 includes a third support rod 71, a fourth support rod 72, and a rotation driving member 73. Among them, one end of the third support rod 71 is connected to the rotation driving member 73, the other end of the third support rod 71 is rotatably connected to one end of the fourth support rod 72, and the other end of the fourth support rod 72 is rotatably connected to the frame. The fourth support rod 72 is a telescopic rod to facilitate adjusting the position of the rotation driving member 73 to adapt to X-ray tubes 1 of different models and X-ray tubes 1 at different positions. Specifically, when grinding the cathode weld 15, the fourth support rod 72 is lengthened to extend the third support rod 71 and the rotation driving member 73 to the same horizontal position as the side wall of the cathode section 12. The third support rod 71 is rotated to fit the rotation driving member 73 against the side wall of the cathode section 12. The rotation driving member 73 drives the X-ray tube 1 to rotate about its own axis through the rotational friction force. When grinding the anode fixed-end weld 16, the fourth support rod 72 is shortened to adjust the third support rod 71 and the rotation driving member 73 to the same horizontal position as the side wall of the cathode section 12. The third support rod 71 is rotated to fit the rotation driving member 73 against the side wall of the cathode section 12. The rotation driving member 73 drives the X-ray tube 1 to rotate about its own axis through the rotational friction force. In this embodiment, the rotation driving member 73 is a rubber wheel. The wheel body of the rubber wheel is used to contact the outer wall of the cathode section 12 of the X-ray tube 1 respectively. The rubber wheel can be driven to rotate manually or by a motor to drive the X-ray tube 1 to rotate. Of course, in other embodiments, the rotation driving mechanism may also be other structures. For example, the rotation driving mechanism includes a pulley and a belt. The belt is sleeved on the pulley, and the belt can be sleeved on the side wall of the cathode section 12 of the X-ray tube 1. The pulley drives the X-ray tube 1 to rotate through the belt.

[0058] In another embodiment, the X-ray tube 1 can be manually rotated manually.

[0059] The following briefly describes the usage method of the weld grinding auxiliary jig provided in this embodiment:

[0060] Please refer to Figures 1 to 4, when removing the cathode weld 15, the anode section 11 of the X-ray tube 1 is oriented downward. The anode section 11 is supported by the rotating mechanism 5 and can rotate. The X-ray tube 1 is rotated manually or by driving the housing of the cathode section 12 of the X-ray tube 1 through the rotation driving mechanism, and the cathode weld 15 is polished by the polishing mechanism 6 to remove the cathode weld 15. After the cathode weld 15 is removed, the cathode cover 14 can be taken off to expose the target disc 13.

[0061] When removing the anode fixed-end weld 16, the X-ray tube 1 is rotated 180 degrees. The cathode section 12 is placed upright at the second support area 22 of the support base plate 2, and the target disc 13 is placed on the support ring 4. The internal target disc 13 is supported by the support ring 4 to prevent the target disc 13 from falling. Then, the X-ray tube 1 is rotated manually or by driving the housing of the cathode section 12 of the X-ray tube 1 through the rotation driving mechanism, and the anode fixed-end weld 16 is polished by the polishing mechanism 6 to remove the anode fixed-end weld 16.

[0062] It should be noted that generally the target disc 13 is rotationally connected to the cathode section 12 and / or the anode section 11. Therefore, placing the target disc 13 on the support ring 4 and rotating the X-ray tube 1 will not cause wear to the target disc 13.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
