Description

Technical Field

[0001] This application relates to the technical field of metal pipe processing, and in particular to an automated welding equipment for metal pipes. Background Technology

[0002] Metal pipe fittings mainly refer to pipe accessories that play a role in connecting and sealing metal pipes. According to their structural type, they are divided into flanges, tees, crosses, elbows, etc.; according to their material, they can be divided into forged pipe fittings, cast pipe fittings, welded pipe fittings, and steel pipe fittings; and according to whether the surface is galvanized, they can be divided into galvanized pipe fittings and non-galvanized pipe fittings.

[0003] Metal pipe fittings require welding equipment to join two sets of pipe fittings during processing. Existing metal pipe fittings have smooth surfaces, and the angle and position of the pipe fittings need to be maintained during installation. However, most welding processes still rely on workers to support the pipe fittings, which can easily lead to shaking and other issues during the fixing process. This lack of stability can cause misalignment or displacement at the connection point of the two sets of metal pipe fittings during welding, affecting the welding efficiency and quality.

[0004] Therefore, those skilled in the art have provided an automated welding equipment for metal pipe fittings to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides an automated welding equipment for metal pipe fittings.

[0006] The automated welding equipment for metal pipe fittings provided in this application adopts the following technical solution:

[0007] An automated welding equipment for metal pipe fittings includes a base plate. Two collars are provided on the left and right sides of the base plate. Two support rods are symmetrically installed below each collar, with the bottom of the support rods fixed to the upper surface of the base plate. A second turntable is rotatably connected inside one collar. Two fixing plates are installed on the upper side of the second turntable. A second hydraulic cylinder is installed between the two fixing plates on the side of the second turntable. A first arc-shaped limiting plate is installed at the telescopic end of the second hydraulic cylinder. A first turntable is rotatably connected to the inner ring of the other collar. Multiple connecting rods are circumferentially fixed between the opposite sides of the second and first turntables. A horizontal plate is installed between the collar sides of the second and first turntables. A first hydraulic rod is installed at the center of the lower surface of the horizontal plate. A second arc-shaped limiting plate is installed at the telescopic end of the first hydraulic rod. A support plate is vertically installed at the upper edge of the base plate. A drive motor is installed on the upper side of the support plate, with the output end of the drive motor fixed to the center of the first turntable.

[0008] Preferably, both ends of the arched surface of the second arc-shaped limiting plate are fixedly connected to limiting rods, and the two limiting rods pass through the two corners of the horizontal plate respectively.

[0009] Preferably, both the second turntable and the first turntable are fixedly fitted with annular guide rails on their outer rings, and the two annular guide rails are respectively fitted inside the two collars.

[0010] Preferably, both the second turntable and the first turntable have slots at their centers.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By passing one pipe fitting through the center of turntable No. 2 and overlapping it with the slot at the center of turntable No. 1, and passing another pipe fitting through the corresponding holes on the two fixed plates, with the bottom end of the pipe fitting overlapping the horizontal welding area, and then activating two hydraulic rods No. 1 and hydraulic cylinder No. 2, the No. 2 arc-shaped limiting plate and the No. 1 arc-shaped limiting plate are moved to limit the two pipe fittings. The entire welding process does not require continuous manual support and stability, effectively ensuring the continuous stability of the pipe fittings during the welding process and improving the welding effect.

[0013] 2. By starting the drive motor, the first turntable is rotated, which in turn drives the second turntable to rotate with multiple connecting rods. This, in turn, drives the fixing plate on the side of the second turntable, the second hydraulic cylinder, and the first arc-shaped limiting plate to rotate. This allows the welding angle of the vertically placed pipe fittings to be changed within a certain adjustment range, making it easier to adapt to different welding requirements.

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.

[0019] refer to Figure 1 and Figure 2 as well as Figure 3 As shown, this application discloses an automated welding equipment for metal pipe fittings, including a base plate 1. Two collars 8 are provided on the left and right sides above the base plate 1. Two support rods 2 are symmetrically installed below each collar 8, and the bottom of the support rods 2 is fixed to the upper surface of the base plate 1. A second turntable 15 is rotatably connected inside one collar 8. Two fixing plates 11 are installed on the upper side of the second turntable 15. A second hydraulic cylinder 9 is installed between the two fixing plates 11 on the side of the second turntable 15. A first arc-shaped limiting plate 10 is installed at the telescopic end of the second hydraulic cylinder 9. The other side... The inner ring of ring 8 is rotatably connected to turntable 13. Turntable 15 and turntable 13 are circumferentially fixedly connected to each other. A horizontal plate 5 is installed between the side of ring 8 and turntable 15 and turntable 13. A hydraulic rod 6 is installed at the center of the lower surface of the horizontal plate 5. A second arc-shaped limiting piece 16 is installed at the telescopic end of hydraulic rod 6. A support plate 3 is installed vertically at the upper edge of the base plate 1. A drive motor 4 is installed on the upper side of the support plate 3, and the output end of the drive motor 4 is fixed to the center of turntable 13.

[0020] The horizontal pipe extends from the center of the second turntable 15, with one end of the pipe overlapping the slot at the center of the first turntable 13 on the other side, providing lateral support for the pipe. Then, another pipe is extended from the corresponding holes on the two fixed plates 11, with the bottom end of the pipe overlapping the welding area of ​​the horizontally placed pipe. Next, the two hydraulic rods 6 and 9 are activated, causing them to push the second arc-shaped limiting plate 16 and the first arc-shaped limiting plate 10 to move to a tight fit with the side of the pipe, thus limiting the two pipes. During the entire welding process, no manual support is required, effectively ensuring the continuous stability of the pipe during welding and improving the welding effect.

[0021] Simultaneously, the drive motor 4 can be started to drive the first turntable 13 to rotate. Then, the rotating first turntable 13, together with multiple connecting rods 12, drives the second turntable 15 to rotate. This can drive the fixing plate 11 on the side of the second turntable 15, the second hydraulic cylinder 9, and the first arc-shaped limiting plate 10 to rotate, so as to change the welding angle of the vertically placed pipe within a certain adjustment range, which is convenient to better adapt to different welding needs.

[0022] refer to Figure 1 and Figure 2 as well as Figure 3 As shown, limit rods 7 are fixedly connected to both ends of the arch surface of the second arc-shaped limit piece 16, and the two limit rods 7 pass through the two corners of the horizontal plate 5 respectively, so that the second arc-shaped limit piece 16 can move along the guide path of the limit rods 7 on both sides, increasing the stability of the second arc-shaped limit piece 16 during the movement process.

[0023] refer to Figure 3 As shown, annular guide rails 14 are fixedly fitted on the outer rings of turntable 15 and turntable 13, and the two annular guide rails 14 are respectively fitted inside the two collars 8 to prevent turntable 13 and turntable 15 from disengaging from the collars 8 during rotation.

[0024] refer to Figure 1 and Figure 2 as well as Figure 3 As shown, slots are provided at the center of both turntable 15 and turntable 13. The slot of turntable 15 extends through its center, while the slot of turntable 13 does not extend through its center. This facilitates support for horizontally placed pipes and also makes it easier to fix the center of turntable 13 to the output end of the drive motor 4.
