[0001] The utility model relates to the technical field of stainless steel pipe welding fixing devices, in particular to a fixing device used for welding stainless steel pipe fittings. Background Art

[0002] Stainless steel pipe welding is a process that involves heating stainless steel pipes to a molten state using a heat source, and then joining two or more stainless steel pipes together with or without a filler material. During the welding process, the stainless steel pipes are placed on a support frame and the two butted pipes are clamped and fixed to ensure close contact between the ends of the two pipes, effectively improving the stability of the butt joint.

[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figure 1-Figure 4 As shown, the utility model proposes a fixing device for welding stainless steel pipe fittings, including a base 1, two symmetrically arranged first support plates 2 are fixedly installed on the top of the base 1, two second support plates 4 are provided between the two first support plates 2, and the bottom ends of the second support plates 4 are fixedly connected to the base 1, and a pipe positioning cylinder 5 is rotatably installed on the above-mentioned first support plate 2. One end of the pipe passes through the pipe positioning cylinder 5 and overlaps the semi-arc-shaped limit opening 41 at the top of the second support plate 4 to ensure that the pipe can be erected on the first support plate 2 and the second support plate 4; a driving Component 6, the driving component 6 consists of a bracket 61, a servo motor 62, a rotating rod 63 and two circular gears 64. The servo motor 62 is mounted above the base 1 through the bracket 61. The output end of the servo motor 62 is fixedly connected to the rotating rod 63. The circular gear 64 is fixedly mounted on the rotating rod 63. A ring gear 52 is fixedly mounted on one end of the pipe positioning cylinder 5. The ring gear 52 is meshed with the circular gear 64. When the servo motor 62 drives the rotating rod 63 to rotate, it can drive the pipe positioning cylinder 5 to rotate, which is convenient for flipping the pipe clamped and fixed at the pipe positioning cylinder 5.

[0029] Furthermore, a circular opening 21 is chiseled on the first support plate 2, and one end of the pipe positioning tube 5 passes through the circular opening 21 and is movably connected thereto. A limiting ring 51 is fixedly installed on the outer wall of the pipe positioning tube 5, and the outer diameter of the limiting ring 51 is larger than the inner diameter of the circular opening 21. Under the limitation of the ring gear 52 and the limiting ring 51, the pipe positioning tube 5 can be prevented from falling off the first support plate 2, effectively improving the stability of the rotational connection between the pipe positioning tube 5 and the first support plate 2; a clamping screw 53 is threadedly installed on the pipe positioning tube 5, and one end of the clamping screw 53 extends to the inside of the pipe positioning tube 5. When the pipe penetrates into the inside of the pipe positioning tube 5, the clamping screw 53 is rotated toward the side of the pipe. When the end of the clamping screw 53 is in close contact with the outer wall of the pipe, the pipe can be clamped and fixed, ensuring that the end of the pipe can be firmly clamped inside the pipe positioning tube 5.

[0030] Secondly, the end of the rotating rod 63 away from the servo motor 62 passes through the circular through-holes drilled on the first support plate 2 and the second support plate 4 and is movably connected thereto. Under the limitation of the support plates, the stability of the rotating rod 63 during rotation can be improved.

[0031] Furthermore, a feeding rack 3 is fixedly installed on the top of the base 1, and the feeding rack 3 is composed of a support frame 31, a side plate 32 and a roller 33. The support frame 31 is fixedly installed on the top of the base 1, and two symmetrical side plates 32 are fixedly installed on the top of the support frame 31. A roller 33 is installed between the two side plates 32 to rotate together, and one end of the pipe is overlapped on the top of the roller 33, which is convenient for pushing the pipe to move horizontally. It can save effort in the process of loading and unloading the pipe, and effectively reduce the labor intensity of the staff.

[0032] Secondly, a number of legs 12 are fixedly installed at the bottom of the base 1 to ensure that the lower surface of the base 1 can maintain a certain distance from the ground; a long strip opening 11 is opened on the base 1, and the long strip opening 11 is arranged between the two second support plates 4, and the joint between the two sections of pipe is located above the long strip opening 11. During welding operations, some of the fallen welding slag can fall from the long strip opening 11 to the ground, making it convenient to clean the welding slag.

[0033] In this embodiment, first, one end of the pipe is passed through the pipe positioning tube 5 and overlapped at the semi-arc limit opening 41 at the top of the second support plate 4. After the ends of the two sections of pipe are close to each other, the clamping screw 53 is rotated toward one side of the pipe, and then the end of the pipe is firmly clamped in the pipe positioning tube 5 to ensure that the butt ends of the two sections of pipe can be stably butt together; when the pipe is fixed, the staff holds the welding gun and stands on one side of the device, and uses the welding gun to weld the annular surface of the pipe joint; during the welding process, the servo motor 62 drives the rotating rod 63 to rotate. Since the circular gear 64 and the ring gear 52 are meshed and connected, the pipe positioning tube 5 can be driven to rotate, and then the pipe can be flipped over, and the unwelded part of the annular surface at the pipe joint can be adjusted, and the unwelded part is made to face the staff, and then the welding process of the entire annular surface can be completed.

[0034] When the pipe welding is completed, the clamping screw 53 is rotated and the clamping fixation of the pipe is released. At this time, the staff pulls the pipe to the side away from the second support plate 4, and supports the part of the pipe away from the second support plate 4 through multiple rollers 33. During the pipe pulling process, the rollers 33 will rotate accordingly, which can reduce the friction resistance encountered when the pipe is pulled, assist the movement of the pipe and achieve the effect of saving effort; when the pipe needs to be inserted into the pipe positioning tube 5, the rollers 33 can also be used to assist the movement of the pipe, reducing the physical strength consumed when pushing the pipe, and effectively reducing the labor intensity of the staff.

[0035] The fixing device in the present application can clamp and fix one end of the pipe close to the welding point through the pipe positioning tube 5. Under the joint support of the first support plate 2 and the second support plate 4, it can ensure that the two sections of pipe are stably docked together, thereby improving the stability during the welding operation. During the welding process, the pipe is flipped by relying on the driving component 6, and the direction of the welding ring surface can be adjusted without manual operation, so that the staff can complete the welding process of the entire welding ring surface while standing in the same fixed position. The operation is simpler, saves time and effort, and effectively improves the convenience of the welding operation.

[0036] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
