Description

Technical Field

[0001] This utility model relates to the technical field of welding positioning, specifically to a high-precision welding positioning fixture for round tube workpieces. Background Technology

[0002] Welding is a process that uses heat, pressure, or both to bond two or more separate metal workpieces (or thermoplastics) together atomically, forming a permanent connection.

[0003] In traditional welding, workers manually align the two workpieces to be welded before starting the welding process. The positioning and fixing of the workpieces are also mostly done manually by the workers, which results in low precision of the welded parts.

[0004] With the continuous improvement of technology, the precision requirements for welded parts are also increasing. Traditional manual positioning and fixing can no longer meet the precision requirements. In response, existing technologies have designed a variety of clamping and positioning fixtures to meet the positioning and fixing needs of workpieces during the welding process.

[0005] However, most of the positioning fixtures currently used for welding are for positioning square tube workpieces, and there is a lack of clamping and positioning fixtures for round tube workpieces. Utility Model Content

[0006] To address the aforementioned problem—namely, the design of a clamping and positioning fixture for welding round tubular workpieces—this invention proposes a high-precision welding and positioning fixture for round tubular workpieces. This fixture includes two rotatably connected clamping mechanisms. Each clamping mechanism includes a lower angle iron, an adjusting frame connected to the lower angle iron, a screw threaded to the top of the adjusting frame, and an upper angle iron connected to the bottom of the screw. The upper angle iron is positioned directly above the lower angle iron.

[0007] A further feature of this invention is that the two adjusting frames on the two clamping mechanisms are arranged in opposite directions.

[0008] A further feature of this invention is that a supporting angle iron is connected to the bottom of the lower angle iron, the supporting angle iron is set perpendicular to the lower angle iron, and a connecting block is welded to the surface of the two supporting angle irons on the side that is close to each other, and the two connecting blocks are rotatably connected.

[0009] A further feature of this invention is that the connecting block has a through hole, the two through holes on the two connecting blocks are coaxially arranged, and are connected by bolts and nuts.

[0010] A further feature of this invention is that the through hole located at the top is a countersunk hole.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The combination of the upper and lower angle irons enables the clamping of round tube workpieces. Furthermore, the cooperation of the two clamping mechanisms ensures that the two workpieces to be welded are precisely aligned, further guaranteeing the welding accuracy.

[0013] 2. By rotating and connecting the two clamping mechanisms, it is possible to clamp and position workpieces with different welding angles, thereby making the tooling more adaptable. Attached Figure Description

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] This utility model proposes a high-precision welding positioning fixture for cylindrical workpieces, including two rotatably connected clamping mechanisms 1. Each clamping mechanism 1 includes a lower angle iron 11 with its opening facing upwards. An adjusting frame 12 is connected to the lower angle iron 11, and a nut is welded to the top of the adjusting frame 12. A screw 13 is internally threaded onto the nut and is vertically positioned. An upper angle iron 131 is rotatably connected to the bottom of the screw 13, positioned directly above the lower angle iron 11 with its opening facing downwards. The cooperation between the upper and lower angle irons 11 enables the clamping of cylindrical workpieces 2. Simultaneously, rotating the screw 13 allows adjustment of the distance between the upper and lower angle irons 11, further enabling the clamping of workpieces 2 with different diameters, thus improving its adaptability.

[0021] The two adjusting frames 12 on the two clamping mechanisms 1 are arranged in opposite directions, that is, when the two clamping mechanisms 1 are rotated to the vertical position, the two adjusting frames 12 are located on both sides of their respective lower angle irons 11. This can avoid interference with the workpiece 2 after the adjusting frames 12 are rotated.

[0022] A supporting angle iron 14 is welded to the bottom of the lower angle iron 11. The supporting angle iron 14 is set perpendicular to the lower angle iron 11 and the opening of the supporting angle iron 14 is set downward to support the clamping mechanism 1.

[0023] Connecting blocks 15 are welded to the surfaces of the two supporting angle irons 14 that are close to each other. Each connecting block 15 has a through hole at the end opposite to the supporting angle iron 14. The through holes of the two connecting blocks 15 are coaxially aligned, and a bolt passes through both holes. A nut is threaded onto the bolt. By rotating the nut, the two connecting blocks 15 can be clamped and loosened. Specifically, when the nut is tightened, the two connecting blocks 15 are fixed in place, preventing relative rotation. When the nut is loosened, the two connecting blocks 15 can rotate relative to each other, thus adjusting the included angle between the two clamping mechanisms 1.

[0024] It should be noted that the through hole at the top is set as a countersunk hole. This can prevent the bolt nut from being higher than the upper surface of the connecting block 15, and further prevent the bolt nut from interfering with the workpiece 2, thus affecting the clamping.

[0025] refer to Figure 2 When both clamping mechanisms 1 are rotated to the vertical position, the two lower angle irons 11 are on the same straight line. At this time, the purpose of butt welding of the ends of two round tube workpieces 2 can be achieved.

[0026] refer to Figure 4 When the two clamping structures are rotated to a perpendicular state, they can achieve the purpose of perpendicular welding of two cylindrical workpieces 2.

[0027] Similarly, by simply rotating the two clamping mechanisms 1 to the welding angle of the workpiece 2, the purpose of welding different workpiece 2 angles can be achieved.

[0028] In summary, the cooperation of the upper angle iron 131 and the lower angle iron 11 in this utility model can achieve the purpose of clamping the round tube workpiece 2. Furthermore, the cooperation of the two clamping mechanisms 1 can ensure that the two workpieces 2 to be welded are precisely aligned, further ensuring the welding accuracy. By rotating and connecting the two clamping mechanisms 1, it is possible to achieve the purpose of clamping and positioning workpieces 2 at different welding angles, thus making this tooling more adaptable.
