[0022] 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.

[0023] like Figure 1-3As shown, a welding fixture for a stainless steel corrugated compensator (cat's ear type) includes a circular base 1, a circular block 2, a support plate 3, a placement mechanism 4, and a clamping mechanism 5. The circular block 2 is located on the top of the circular base 1 and is detachable for easy replacement with flanges of different sizes. The support plate 3 is fixedly sleeved on the outer wall of the circular block 2, and a flange is sleeved on the circular block 2. Both the placement mechanism 4 and the clamping mechanism 5 are mounted on the circular base 1. The placement mechanism 4 includes a moving block 43, a connecting rod 47, a trapezoidal block 48, and a spring 49. The moving block 43 is slidably connected to the circular base. The top of the circular base 1 is provided with cat ears. A hole is provided on the movable block 43. One end of the connecting rod 47 is slidably connected inside the hole. A trapezoidal block 48 is fixedly connected to the other end of the connecting rod 47. A spring 49 is located inside the connecting rod 47, and its two ends are fixedly connected to the inner wall of the connecting rod 47 and the outer wall of the movable block 43, respectively. The inclined surface of the trapezoidal block 48 contacts the placed cat ears, and fixation is achieved through the inclined surface abutment, allowing the fixture to fix cat ears of different sizes. A limit groove 41 is provided on the top of the circular base 1. The bottom of the moving block 43 is fixedly connected to a slider 42, which is slidably connected inside a limiting groove 41. A limiting rod is fixedly connected inside the limiting groove 41, and the limiting rod passes through the slider 42 and is slidably connected to the slider 42. The limiting groove 41, slider 42, and limiting rod are provided to ensure the stable horizontal movement of the moving block 43. A connecting plate 44 is fixedly connected to the outer wall of the moving block 43, and a fastening bolt 45 is threaded onto the connecting plate 44. By setting the fastening bolt 45 and the connecting plate 44, the moving block 43 can be moved to a suitable position. After positioning, the movable block 43 can be fixed by tightening the fastening bolt 45. By adjusting the position of the movable block 43, cat ears can be welded onto flanges of different sizes. A positioning rod 46 is fixedly connected to the top of the movable block 43, and the cat ears are fitted onto the positioning rod 46. By setting the positioning rod 46, the placed cat ears can be initially positioned. A vertical rod 6 is set on the top of the round seat 1, and the vertical rod 6 passes through the mounting hole on the flange. The vertical rod 6 can be detached and installed. By setting the vertical rod 6, the position of the cat ears welded onto each flange can be consistent.

[0024] Specifically, by pulling the connecting rod 47, the trapezoidal block 48 is moved away from the moving block 43, and then the cat ear is placed on the positioning rod 46. The pulled trapezoidal block 48 is released so that it is reset under the action of the spring 49 to clamp and fix the cat ear, so as to avoid displacement during welding and affect the welding quality.

[0025] like Figure 1 , 4As shown, the clamping mechanism 5 includes a clamping block 51, a moving rod 52, a limiting hole 53, a rectangular groove 54, and a bidirectional threaded rod 55. The moving rod 52 is fixedly connected to the bottom of the clamping block 51. The rectangular groove 54 is opened at the bottom of the round base 1, and the limiting hole 53 is opened at the top of the round base 1. The moving rod 52 passes through the limiting hole 53 and is slidably connected to it. There are two clamping blocks 51 and two moving rods 52. The clamping block 51 is provided with an arc surface, which can improve the clamping effect. The position of the clamping block 51 will not interfere with the placement mechanism 4 when it moves. The bidirectional threaded rod 55 is rotatably connected inside the rectangular groove 54 via a bearing, and the bidirectional threaded rod 55 passes through the movable rod 52 and is threadedly connected to the movable rod 52. By setting the bidirectional threaded rod 55, the two movable rods 52 can be driven to move closer or further apart when rotated. One end of the bidirectional threaded rod 55 passes through the inner wall of the rectangular groove 54 and extends to the outside of the round seat 1. One end of the bidirectional threaded rod 55 is fixedly connected to a rotating block 56, and the bidirectional threaded rod 55 is rotatably connected to the round seat 1. The rotating block 56 facilitates the rotation of the bidirectional threaded rod 55.

[0026] Specifically, the flange is positioned by placing it on the support plate 3 and allowing the upright 6 to pass through the mounting hole on the flange. The rotating block 56 drives the bidirectional threaded rod 55 to rotate, and the bidirectional threaded rod 55 drives the clamping block 51 to clamp and fix the flange through the moving rod 52, thereby improving the stability of the welding.

[0027] The working principle of this utility model is as follows: By placing the flange on the support plate 3 and allowing the upright rod 6 to pass through the mounting hole on the flange, the flange is positioned. Rotating the rotating block 56 drives the bidirectional threaded rod 55 to rotate. The bidirectional threaded rod 55 drives the clamping block 51 to clamp and fix the flange through the moving rod 52, thereby improving the stability of welding. By pulling the connecting rod 47, the trapezoidal block 48 is moved away from the moving block 43. Then, the cat ear is placed on the positioning rod 46. Releasing the pulled trapezoidal block 48 allows it to reset under the action of the spring 49, clamping and fixing the cat ear, thus preventing displacement during welding and affecting the welding quality.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
