Description

Technical Field

[0001] This utility model relates to the field of welding technology, and specifically discloses a rotary welding fixture. Background Technology

[0002] Welding fixtures play several important roles in welding operations, primarily including ensuring workpiece stability, improving welding efficiency, reducing welding deformation, ensuring welding accuracy, increasing safety, and adapting to the needs of different workpieces. During welding operations, operators use fixtures to ensure that the workpiece is held in the correct position, ensuring that the weld accuracy meets welding standards, thereby improving product quality.

[0003] Currently, in industrial sectors with high welding precision requirements, such as automobile manufacturing and energy equipment, some structures require the use of ring welded components for structural connections. Ring welded components often employ snap-fit ​​or oblique insertion methods to ensure a more secure and stable connection, preventing loosening. In actual welding operations, workers typically use fixed clamps to stably connect the two welded components. They then use welding equipment such as welding torches to spot weld or perform weld treatments at the joint, assembling the two components into a single structure. To ensure welding quality, workers perform welding operations from multiple angles around the welded components, requiring frequent adjustments to their positions. This existing technology not only consumes significant labor resources but also easily reduces welding quality during position changes, lowering welding precision and making it difficult to maintain a stable standard range, thus affecting product quality.

A first damping seat 11 is fixedly engaged at the bottom of the extension platform 2. Two second damping seats 12 are fastened to the bottom of the base platform 1, and the two second damping seats 12 are symmetrically arranged. By setting the first damping seat 11 and the second damping seat 12, the vibration frequency can be effectively reduced, increasing the stability of the overall structure.

[0025] A first frame 3 is fixedly installed on the extension stage 2. A first motor 13 is fixedly installed on the side of the first frame 3 facing away from the base stage 1. A stabilizing plate 14, which is fastened to the extension stage 2, is fixedly installed at the bottom of the first motor 13 to ensure the stability of the first motor 13. The output shaft of the first motor 13 is arranged laterally between the first frame 3 and the base stage 1. A first support plate 15 is fixedly fitted at the end of the output shaft of the first motor 13. The first support plate 15 is fastened to the first clamping plate 4.

[0026] The top of the base platform 1 is provided with a first sliding plate 16 and a second sliding plate 17 that slide laterally. A first lead screw 18 and a second lead screw 19 are rotatably mounted on the side of the base platform 1. Both ends of the first lead screw 18 and the second lead screw 19 are rotatably fitted with lead screw seats, which are all securely connected to the base platform 1. The first lead screw 18 and the second lead screw 19 are arranged parallel to each other, with the first lead screw 18 positioned above the second lead screw 19. A second motor 20 and a third motor 21 are fixedly mounted on the side of the base platform 1. The output shafts of the second motor 20 and the third motor 21 are both arranged laterally. The output shaft of the second motor 20 is connected to the first lead screw 18 via a coupling, and the output shaft of the third motor 21 is connected to the second lead screw 19 via a coupling. The first lead screw 18 and the second lead screw 19 are respectively threadedly connected to the first lead screw nut 22 and the second lead screw nut 23. The first lead screw nut 22 is fastened to the first slide plate 16 through the first receiving plate 24, and the second lead screw nut 23 is fastened to the second slide plate 17 through the second receiving plate 25. The bottom of the first slide plate 16 and the second slide plate 17 are provided with sliding grooves that slide with the top of the base platform 1. The top of the first slide plate 16 and the second slide plate 17 are respectively fixedly installed with the second frame 5 and the third frame 6. By setting the second motor 20 and the third motor 21, the first lead screw 18 and the second lead screw 19 can be driven to rotate, thereby causing the first slide plate 16 and the second slide plate 17 to slide laterally on the top of the base platform 1, thereby adjusting the arrangement position of the second frame 5 and the third frame 6.

[0027] The second frame 5 is rotatably mounted with a second clamping plate 7 on the side facing the extension stage 2, and the third frame 6 is rotatably mounted with a third clamping plate 8 on the side facing away from the extension stage 2.

[0028] A fourth frame 9 is fixedly installed on the top of the base platform 1. The fourth frame 9 is located on the side of the base platform 1 away from the outer extension platform 2. A rotating shaft 26 is rotatably installed inside the fourth frame 9. The rotating shaft 26 is arranged laterally with its two ends respectively located on both sides of the fourth frame 9. A fourth clamping plate 10 is fixedly fitted onto the end of the rotating shaft 26 facing the third clamping plate 8. A fourth motor 27 is located on the side of the base platform 1 away from the outer extension platform 2. A motor bracket is fixedly fitted onto the outside of the fourth motor 27. The motor bracket is tightly connected to the second shock absorber 12 on the right side. The output shaft of the fourth motor 27 is arranged laterally. A second pulley 29 is fixedly fitted onto the end of the output shaft of the fourth motor 27. A first pulley 28 is fixedly fitted onto the end of the rotating shaft 26 facing the fourth motor 27. A belt 30 is provided between the first pulley 28 and the second pulley 29 for transmission connection, thereby enabling the fourth motor 27 to drive the rotating shaft 26 and the fourth clamping plate 10 to rotate.

[0029] The first clamping plate 4, the second clamping plate 7, the third clamping plate 8, and the fourth clamping plate 10 are all used to clamp the welded parts. The first clamping plate 4, the second clamping plate 7, the third clamping plate 8, and the fourth clamping plate 10 are all provided with a plurality of evenly arranged clamping teeth 31. The inner tooth surface of the clamping teeth 31 is an arc-shaped groove structure. The inner tooth surface of the clamping teeth 31 contacts the welded parts, thereby stably clamping the welded parts inside the first clamping plate 4, the second clamping plate 7, the third clamping plate 8, and the fourth clamping plate 10.

[0030] The working principle of this utility model is as follows:

[0031] The operator can stably place four welding parts inside the first clamping plate 4, the second clamping plate 7, the third clamping plate 8, and the fourth clamping plate 10, respectively. By activating the second motor 20 and the third motor 21, the first lead screw 18 and the second lead screw 19 can be rotated, causing the first sliding plate 16 and the second sliding plate 17 to slide on the top of the base platform 1. This brings the second clamping plate 7 mounted on the second frame 5 closer to the first clamping plate 4, and the third clamping plate 8 mounted on the third frame 6 closer to the fourth clamping plate 10, thus bringing the welding parts into contact with each other. The operator can hold the welding equipment and bring the welding head of the equipment into contact with the contact edges of the welding parts mounted on the two first clamping plates 4 and 7. The output shaft of the first motor 13 can drive the first clamping plates 4 and 7 to rotate slowly together, causing the welding parts mounted on the first clamping plates 4 and 7 to rotate together, allowing the operator to perform welding operations on the two welding parts. Subsequently, the operator can move to one side of the fourth frame 9 and activate the fourth motor 27 to perform welding operations on the welding parts mounted on the third clamping plates 8 and 10.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
