[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figure 2-9 As shown, this utility model discloses a welding fixture for X-ray tube core anode welding, including a controller 1, a welding torch 2 electrically connected to the controller 1, a drive motor 7 electrically connected to the controller 1, a support base 3, a fine-tuning plate 4, a mounting base 5, and a fixing base 6.
[0029] The top surface of the support base 3 has a first through hole, and a mounting bracket 31 extends upward from the side of the support base 3, with the drive motor 7 housed within the support base 3. It should be understood that the drive motor 7 is housed within the support base 3, and the rotating rod of the drive motor 7 is vertically upward.
[0030] One end of the fine-tuning plate 4 is rotatably mounted on the top of the mounting bracket 31.
[0031] Mounting base 5 is provided on the top surface of support base 3, wherein mounting base 5 is provided with a second through hole corresponding to the first through hole, and the rotating shaft of drive motor 7 passes through the first through hole and the second through hole.
[0032] The bottom end of the fixed base 6 is connected to the rotating shaft of the drive motor 7, so that the fixed base 6 can be driven to rotate by the drive motor 7. It should be understood that the fixed base 6 is set above the mounting base 5, and the mounting base 5 will not rotate when the rotating shaft of the drive motor 7 drives the fixed base 6 to rotate.
[0033] In this embodiment, the top of the mounting base 6 is provided with a mounting groove 61 for mounting the X-ray tube 20, and the welding torch 2 is disposed on the other end of the fine-tuning plate 4 and faces the mounting groove 61. It should be understood that since the X-ray tube 20 is mounted in the mounting groove 61 of the mounting base 6, when the drive motor 7 drives the mounting base 6 to rotate, it will simultaneously drive the X-ray tube 20 to rotate. During the rotation of the X-ray tube 20, the welding torch 2 can be used to weld the connection between the metal shell 02 and the bearing 01 of the X-ray tube 20, which improves the stability of the welding process and ensures the welding quality of the metal shell 02 and the bearing 01, thereby effectively improving the service life of the product.
[0034] In this embodiment, the top of the side wall of the mounting groove 61 of the fixing base 6 is provided with a first locking structure 62, a second locking structure 63 and a third locking structure 64 for locking the metal shell 02 of the X-ray tube core 20.
[0035] Specifically, the first locking structure 62 includes a first mounting block 621 disposed at the top of the side wall of the mounting groove 61 of the fixed base 6 and a first clamping block 622 threadedly connected to the first mounting block 621. One end of the first clamping block 622 is provided with a first slot 623 for locking the metal shell 02 of the X-ray tube 20. The second locking structure 63 includes a second mounting block 631 disposed at the top of the side wall of the mounting groove 61 of the fixed base 6 and a second clamping block 632 threadedly connected to the second mounting block 631. One end of the second clamping block 632 is provided with a second slot 633 for locking the metal shell 02 of the X-ray tube 20. The third locking structure 64 includes a third mounting block 641 disposed at the top of the side wall of the mounting groove 61 of the fixed base 6 and a third clamping block 642 threadedly connected to the third mounting block 641. One end of the third clamping block 642 is provided with a third slot 643 for locking the metal shell 02 of the X-ray tube 20. It should be understood that the first locking structure 62, the second locking structure 63 and the third locking structure 64 are triangularly distributed on the top of the fixing base 6, which can more securely lock the metal shell 02 to the fixing base 6. After the X-ray tube core is welded, the first clamping block 622, the second clamping block 632 and the third clamping block 642 can be removed from the corresponding mounting blocks, and the locking state of the metal shell 02 can be released.
[0036] Furthermore, the bottom wall of the mounting groove 61 of the fixing base 6 is provided with a first sliding groove 65, a second sliding groove 66, and a third sliding groove 67 at intervals. A first slider 651 is slidably disposed in the first sliding groove 65, a second slider 661 is slidably disposed in the second sliding groove 66, and a third slider 671 is slidably disposed in the third sliding groove 67. A first clamping plate 6511 extends upward from the first slider 651, a second clamping plate 6611 extends upward from the second slider 661, and a third clamping plate 6711 extends upward from the third slider 671. The target disk 03 of the X-ray tube core 20 is located in the clamping space formed by the first clamping plate 6511, the second clamping plate 6611, and the third clamping plate 6711. It should be understood that the clamping space (hereinafter referred to as the clamping space) formed by the first clamping plate 6511, the second clamping plate 6611 and the third clamping plate 6711 can be changed according to the size of the target plate. When the first slider 651, the second slider 661 and the third slider 671 slide out along the corresponding slide groove in a direction away from the center of the fixed base 6, the clamping space will become larger to accommodate a larger target plate. When the first slider 651, the second slider 661 and the third slider 671 slide in along the corresponding slide groove in a direction closer to the center of the fixed base 6, the clamping space will shrink, so as to accommodate a smaller target plate size while clamping the target plate.
[0037] Specifically, the first slider 651, the second slider 661 and the third slider 671 are provided with grooves 69 on both sides, and the fourth slide groove 681, the fifth slide groove 682 and the sixth slide groove 683 are provided with slide bars that match the grooves 69 on both sides, so that the first slider 651, the second slider 661 and the third slider 671 can be limited and slid in the fourth slide groove 681, the fifth slide groove 682 and the sixth slide groove 683.
[0038] Furthermore, the bottom end of the fixed base 6 extends downward to provide an extension 68 connected to the rotation shaft of the drive motor 7. The top end of the extension 68 is provided with a fourth slide groove 681 corresponding to the first slide groove 65, a fifth slide groove 682 corresponding to the second slide groove 66, and a sixth slide groove 683 corresponding to the third slide groove 67. The first slider 651 is slidably disposed in the first slide groove 65 and the fourth slide groove 681, the second slider 661 is disposed in the second slide groove 66 and the fifth slide groove 682, and the third slider 671 is disposed in the third slide groove 67 and the sixth slide groove 683.
[0039] Preferably, the fixing base 6 is cylindrical and the extension 68 is cylindrical, wherein the outer diameter of the extension 68 is smaller than the outer diameter of the fixing base 6, the length of the first slide groove 65 is longer than the length of the fourth slide groove 681, the length of the second slide groove 66 is longer than the length of the fifth slide groove 682, and the length of the third slide groove 67 is longer than the length of the sixth slide groove 683. It should be understood that, since the fourth slide groove 681, the fifth slide groove 682, and the sixth slide groove 683 prevent the first slider 651, the second slider 661, and the third slider 671 from falling off during sliding, and the first slide groove 65, the second slide groove 66, and the third slide groove 67 can also accommodate the first clamping plate 6511, the second clamping plate 6611, and the third clamping plate 6711, the first slide groove 65, the second slide groove 66, and the third slide groove 67 can provide more adjustment space for the sliders, allowing the clamping space to be expanded. In addition, one end of the first slide groove 65, the second slide groove 66, and the third slide groove 67 is exposed outside the top of the extension 68.
[0040] In this embodiment, one end of the fine-tuning plate 4 extends to form an extension plate 41. The extension plate 41 has symmetrically arranged first slots 411 and second slots 412. A first screw passes through the first slot 411, and a second screw passes through the second slot 412, so that the extension plate 41 is mounted on the top of the mounting bracket 31 using the first and second screws. It should be understood that the top of the mounting bracket 31 has a first threaded hole corresponding to the first slot 411 and a second threaded hole corresponding to the second slot 412, spaced apart. The first screw passes through the first slot 411 and is threaded into the first threaded hole, and the second screw passes through the second slot 412 and is threaded into the second threaded hole. Tightening or loosening the first and second screws allows the extension plate 41 to rotate, thereby rotating the fine-tuning plate 4 and adjusting the orientation of the welding 2.
[0041] Specifically, both the first slot 411 and the second slot 412 are elongated arc shapes. It should be understood that the extension plate 41 can rotate along the elongated arc shape of the first slot 411 and the second slot 412. The fine-tuning plate 4 can be manually rotated according to actual needs. The first screw and the second screw inserted therein can keep the welding torch 2 at an appropriate and safe distance from the X-ray tube core to prevent over-rotation and welding of the wrong place by the welding torch 2.
[0042] In this embodiment, the welding torch 2 is detachably mounted on the other end of the fine-tuning plate 4 via a clamping block 42. It should be understood that the side end of the clamping block 42 is threadedly connected to the fine-tuning plate 4 with screws, allowing for the replacement of different welding torches 2 as needed.
[0043] Furthermore, the controller 1, welding torch 2, and drive motor 7 in this application can all be implemented using existing products, and their principles and structures will not be described in detail here.
[0044] Specific working principle:
[0045] The X-ray tube 20 is installed in the mounting slot 61 of the mounting base 6, and then the X-ray tube 20 is fixed by the three locking structures at the top of the mounting base 6. Then, the direction of the welding torch 2 can be adjusted by rotating the extension plate 41. After the position is adjusted accurately, the drive motor 7 can be started by the controller 1 to make the mounting base 6 rotate with the X-ray tube 20. At this time, the welding torch 2 can continuously weld the welding point 04, so that the anode target and the metal shell can be stably and firmly welded together, thereby improving the product strength and service life.
