[0032] Other objects and advantages of this utility model will become clear by explaining the preferred embodiments of the present application below.

[0033] like Figures 1 to 5 As shown, the horizontal welding positioner has a base 1 and a transmission box 2 located on the upper part of one side of the base 1 in the longitudinal direction. The transmission box 2 has a main shaft 3 supported and rotatable. The transmission box 2 is provided with a power element that is connected to the main shaft 3 to drive the main shaft 3 to rotate. The power element can be, for example, an electric motor.

[0034] A chuck 4 is provided at the end of the spindle 3. The chuck 4 has multiple jaws to clamp the first workpiece 5, ensuring good coaxiality. A tailstock unit 19 is provided on the upper part of the other side of the base 1 along its length direction, opposite to the chuck 4. The tailstock unit 19 and the base 1 are aligned along the length direction of the base 1 (e.g., ...). Figure 1 The tailstock unit 19 is slidably connected to the base 1 (as shown in the diagram), and has a tip 23 for pressing against the second workpiece 6. In some embodiments, the tailstock unit 19 is connected to the base 1 via a main slide rail 18, which may be, for example, a linear guide rail.

[0035] The horizontal welding positioner also includes an adjustment unit 9 for supporting the welding torch 7. The adjustment unit 9 is slidably connected to the base 1 along the length of the base 1, thereby adapting to the welding requirements of workpieces of different lengths. In some embodiments, the adjustment unit 9 is connected to the base 1 via a secondary slide rail 17. The secondary slide rail 17 can be, for example, a linear guide rail.

[0036] In this embodiment, the first workpiece 5 is fixed by the chuck 4, and the second workpiece 6 and the first workpiece 5 are pressed together by the tailstock unit 19. Then, the gap to be welded between the first workpiece 5 and the second workpiece 6 is welded by the welding torch 7. During the welding process, the chuck 4 drives the first workpiece 5 and the second workpiece 6 to rotate, and completes the welding of the complete weld around the workpiece.

[0037] In some embodiments, the tailstock unit 19 includes a tailstock bracket 20, the upper part of which is provided with a guide rod 22, the guide rod 22 being slidably connected to the tailstock bracket 20 in the length direction; the tailstock bracket 20 is also provided with a pressing drive member 21, the pressing drive member 21 being connected to the guide rod 22 and used to push and pull the guide rod 22 to move in the length direction of the horizontal welding positioner; the tip 23 is located at the end of the guide rod 22 facing the transmission box 2.

[0038] In this embodiment, the guide rod 22 is slidably connected to the tailstock bracket 20, and a center point 23 is provided at the end of the guide rod 22 to ensure the accuracy requirements when the first workpiece 5 and the second workpiece 6 rotate. The clamping drive 21 pushes and pulls the guide rod 22 along the length direction through the linkage plate 24, thereby quickly completing the workpiece clamping and unloading work after welding, improving work efficiency. The clamping drive 21 can be, for example, a cylinder.

[0039] In some embodiments, the adjustment unit 9 includes a swing seat 11, which is connected to the base 1 via a swing pin 25. The extension direction of the swing pin 25 is the same as the length direction. Through the above-mentioned swingable connection method, it is convenient to adjust the relative position of the welding torch 7 and the workpiece, thereby adapting to the welding requirements of workpieces with different diameters.

[0040] In some embodiments, the adjustment unit 9 includes a first sliding seat 13, which is slidably connected to the swing seat 11 in a direction perpendicular to the length direction. The first sliding seat 13 can be connected to the swing seat 11, for example, via a first slide rail 12. A further driving element 10 is fixedly connected to the swing seat 11, and the output end of the driving element 10 is connected to the first sliding seat 13. This allows the driving element 10 to push or pull the first sliding seat 13 to move along a direction perpendicular to the length direction, thereby facilitating the adjustment of the relative position between the welding torch 7 and the workpiece to adapt to the welding requirements of workpieces of different sizes.

[0041] In some embodiments, the adjustment unit 9 includes a second sliding seat 15, which is slidably connected to the first sliding seat 13 in the length direction. The welding torch 7 is connected to the second sliding seat 15 via a bracket 8. In this embodiment, the slidable connection between the second sliding seat 15 and the first sliding seat 13 allows for fine-tuning of the position of the welding torch 7 in the length direction, improving work efficiency. In this embodiment, a lead screw 14 can be used to drive the second sliding seat 15 to slide. For example, a nut that cooperates with the lead screw 14 can be provided on the second sliding seat 15. When the lead screw 14 rotates, it can drive the second sliding seat 15 to move in the length direction through the nut.

[0042] In some embodiments, the first workpiece 5 and the second workpiece 6 are cylindrical; the horizontal welding positioner further includes a front blocking plate 26 that abuts against the first workpiece 5 and a rear blocking plate 16 that abuts against the second workpiece 6. The front blocking plate 26 is connected to the chuck 4, and the rear blocking plate 16 is connected to the center point 23. The workpiece is fixed by the front blocking plate 26 and the rear blocking plate 16, which facilitates clamping and improves work efficiency and accuracy.

[0043] The apparatus of this application has been described in detail with reference to the preferred technical solutions. However, it should be noted that, without departing from the spirit of this application, those skilled in the art can make any modifications, alterations, and variations based on the above disclosure. This application includes the above-described specific embodiments and any equivalent forms thereof.
