Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary equipment, and in particular to sheet welding auxiliary equipment. Background Art

[0002] During the manufacturing process of oil drill pipe centralizers, the raised structures on their surfaces play a crucial role. These raised structures not only affect the centralizer's performance and stability in the wellbore but also directly impact the efficiency and safety of drilling operations. However, due to technical and process limitations, some of the raised structures on oil drill pipe centralizers currently require welding to secure them.

[0003] In actual production scenarios, manual welding presents numerous uncontrollable factors. Despite the skills and experience of welders, faced with the high-precision requirement of evenly distributing bumps across the stabilizer surface, manual operation often makes it difficult to ensure that each bump is positioned exactly as designed. The manual welding process is affected by a variety of factors, including worker fatigue, concentration, and the stability of their technique, making uneven bump distribution a common occurrence. This uneven distribution of bumps can negatively impact the performance of oil drill pipe centralizers, such as reducing their effectiveness in the wellbore, increasing friction and wear between the drill pipe and the wellbore wall, and even potentially causing drilling accidents, posing significant safety risks and economic losses to oil production operations.

[0033] Reference Figures 1 to 3, which is the first embodiment of the present utility model, proposes a workpiece welding auxiliary equipment for uniformly welding workpieces on a petroleum drill pipe centralizer, including a frame 1, the frame 1 having a first mounting portion 101 and a second mounting portion 102; a first clamping jaw 2 is rotatably set on the first mounting portion 101; a second clamping jaw 3 is rotatably and slidably set on the second mounting portion 102, coinciding with the axis of the first clamping jaw 2 and arranged oppositely; there are several arc-shaped mounting frames 4, one end of the first arc-shaped mounting frame 4 is hinged on the first clamping jaw 2, and several arc-shaped mounting frames 4 are connected end to end to form a mounting ring, and the arc-shaped mounting frame 4 has a mounting groove 401 for placing the workpiece.

[0034] In this embodiment, a workpiece welding assist device is designed to address the uneven welding problem of the protrusion on oil drill pipe centralizers in related art. In actual production, the frame 1 is meticulously crafted from high-strength alloy steel, offering exceptional stability and durability. The first mounting portion 101 and second mounting portion 102 are precision-machined to ensure accurate and reliable installation. The first jaw 2 is pivotally mounted on the first mounting portion 101 via a high-precision shaft. The shaft's surface has been specially treated to achieve low friction and high wear resistance, enabling easy and flexible angle adjustment of the first jaw 2 to accommodate various welding requirements. The second jaw 3 is pivotally and slidably mounted on the second mounting portion 102, enabling precise position adjustment and free rotation as needed. It seamlessly mates with the first jaw 2 to accommodate oil drill pipe centralizers of varying sizes and shapes. The curved mounting bracket 4 is constructed from a high-temperature and corrosion-resistant special alloy, providing sufficient strength and rigidity to withstand the high temperatures and stresses of the welding process. One end of the first curved mounting bracket 4 is hinged to the first clamping jaw 2 via a sturdy hinge. The hinge design allows the curved mounting bracket 4 to swing freely within a certain range, facilitating the installation and adjustment of the workpiece. Several curved mounting brackets 4 are connected end to end to form a mounting ring. The connection uses a precise snap-fit ​​structure to ensure the integrity and stability of the mounting ring. The mounting groove 401 is carefully designed based on the shape of the workpiece, with a contour that perfectly fits the workpiece, ensuring that the workpiece can be stably placed within it without displacement or shaking during the welding process.

[0035] The device's ingenious design enables uniform welding of workpieces onto oil drill pipe centralizers, significantly improving welding quality and efficiency. The flexible configuration of the first and second jaws (2, 3) accommodates centralizers of varying sizes and shapes, making the device widely applicable. The curved mounting bracket (4) facilitates and stabilizes workpiece placement, improving welding precision and consistency. Furthermore, high-quality materials and sophisticated machining ensure the device's durability and reliability, reducing maintenance costs and operational risks.

[0036] Furthermore, there are two mounting rings, and the first arc-shaped mounting frames 4 of the two mounting rings are hinged to the first clamping jaw 2 and the second clamping jaw 3 respectively.

[0037] In this embodiment, the first curved mounting bracket 4 of the first mounting ring is hinged to the first jaw 2 via a high-strength hinge. This hinged connection is secure and reliable, capable of withstanding significant tension and torque. The first curved mounting bracket 4 of the second mounting ring is similarly hinged to the second jaw 3 via a sturdy hinge, allowing the two mounting rings to be adjusted and operated independently. During use, workpieces can be placed on both mounting rings simultaneously as needed. By adjusting the position and angle of the first and second jaws 2 and 3, the workpieces can be precisely aligned with the welding position on the oil drill pipe centralizer. This allows welding operations to be performed simultaneously on both mounting rings, significantly reducing welding time and improving production efficiency.

[0038] The advantage lies in the fact that the two mounting rings greatly facilitate welding operations. On the one hand, they enable the simultaneous welding of multiple workpieces, significantly improving production efficiency and meeting the needs of large-scale production. On the other hand, the articulated design at different positions allows for more flexible adjustment of the mounting rings, accommodating varying welding angles and positions, enhancing the versatility and practicality of the equipment.

[0039] Furthermore, the shape of the mounting groove 401 is adapted to the shape of the workpiece.

[0040] In this embodiment, the design of the mounting slot 401 fully considers the diversity of workpiece shapes and is adjusted according to the specific shape and size of the workpiece.

[0041] Furthermore, the second clamping jaw 3 has a positioning portion 301 and also includes a positioning rod 5. The positioning rod 5 is slidably arranged on the frame 1. After the positioning rod 5 slides, one end of the positioning rod 5 abuts against or releases the abutment with the positioning portion 301.

[0042] In this embodiment, the positioning rod 5 is slidably mounted on the frame 1 via a high-precision slideway. The slideway is made of high-quality aluminum alloy with excellent wear resistance and guiding properties. One end of the positioning rod 5 is designed to match the positioning portion 301 of the second clamping jaw 3. When the second clamping jaw 3 needs to be positioned, the operator can easily slide the positioning rod 5 so that one end of the positioning rod 5 tightly abuts the positioning portion 301 of the second clamping jaw 3, thereby fixing the position of the second clamping jaw 3 and ensuring that the second clamping jaw 3 does not move or shake during the welding process. When the second clamping jaw 3 needs to be adjusted, the operator simply slides the positioning rod 5 away to release the abutment state, and the position and angle of the second clamping jaw 3 can be freely adjusted.

[0043] The advantage is that the positioning rod 5 provides reliable positioning of the second clamping jaw 3. During the welding process, it effectively fixes the position of the second clamping jaw 3, improving welding precision and stability. Furthermore, the sliding design makes operation more convenient and quick, allowing operators to quickly position and release the clamping jaw when needed, improving work efficiency. Furthermore, the high-quality materials and sophisticated processing ensure the durability and reliability of the positioning rod 5, reducing equipment maintenance costs.

[0044] Furthermore, it also includes a guide plate 6, which is arranged on the frame 1. The guide plate 6 has a guide portion 601. After the mounting ring rotates, it abuts against or releases the abutment with the guide portion 601.

[0045] In this embodiment, the guide plate 6 is made of sturdy stainless steel and is securely fastened to the frame 1 by bolts. The guide portion 601 of the guide plate 6 is curved, and its surface is finely polished for excellent smoothness and wear resistance. As the mounting ring rotates, it can closely abut or release against the guide portion 601. The curved surface of the guide portion 601 guides the rotation direction of the mounting ring, ensuring that the workpiece is accurately aligned with the welding position. The curvature and size of the guide portion 601 are carefully designed to perfectly match the rotation trajectory of the mounting ring, making the rotation of the mounting ring smoother and more precise.

[0046] The advantage is that the guide plate 6 provides precise guidance for the rotation of the mounting ring, significantly improving the precision and accuracy of welding. During the welding process, the curved surface of the guide portion 601 effectively guides the rotation of the mounting ring, avoiding workpiece position deviations caused by inaccurate rotation. Furthermore, the strong material and sophisticated processing of the guide plate 6 ensure its durability and reliability, providing long-term and stable guidance for the rotation of the mounting ring. Furthermore, the design of the guide portion 601 makes operation more convenient, reduces human error, and improves work efficiency.

[0047] Furthermore, the first clamping jaw 2 has a first scale 201 , and the first mounting portion 101 has a second scale 1011 .

[0048] In this embodiment, the first clamping jaw 2 is engraved with a clear first scale 201. The scale lines are engraved using high-precision laser engraving technology, ensuring clarity and wear resistance. A corresponding second scale 1011 is engraved on the first mounting portion 101. The precision of the scale is rigorously calibrated to ensure accurate reflection of the position and angle of the first clamping jaw 2. During use, the operator can precisely adjust the position and angle of the first clamping jaw 2 by reading the scale, ensuring accurate alignment of the workpiece with the weld position on the oil drill pipe centralizer. The scale design also facilitates repeated operations, improving work efficiency and weld consistency.

[0049] The advantages of this method are that the arrangement of first scale 201 and second scale 1011 provides the operator with an accurate reference, making the position and angle adjustment of first clamping jaw 2 more convenient and precise. During the welding process, the operator can quickly adjust first clamping jaw 2 according to the scale, ensuring welding accuracy and consistency. Furthermore, the clear and wear-resistant scale allows the operator to accurately adjust the scale over time, thereby improving the reliability and service life of the equipment.

[0050] Furthermore, it also includes a first fastener 7 , which is arranged on the first clamping jaw 2 ; and a second fastener 8 is arranged on the second clamping jaw 3 .

[0051] In this embodiment, the first fastener 7 and second fastener 8, respectively, utilize a high-strength bolt and nut structure, undergoing a special surface treatment for excellent rust and corrosion resistance. The first fastener 7 is mounted on the first clamping jaw 2. By tightening the bolts, the first clamping jaw 2 is securely fixed to the oil drill pipe centralizer, ensuring that the first clamping jaw 2 does not loosen or shift during the welding process. The second fastener 8 is mounted on the second clamping jaw 3. Similarly, by tightening the bolts, the second clamping jaw 3 is securely fixed to the centralizer. The rational design of the fasteners allows for easy operation and quick tightening and loosening.

[0052] The advantage is that the arrangement of the first and second fasteners 7 and 8 provides reliable support for the clamping jaws. This effectively secures the position of the clamping jaws during welding, improving welding stability and precision. Furthermore, the convenient design allows operators to quickly tighten and loosen the clamps, improving work efficiency. Furthermore, the high-strength material and excellent surface treatment ensure the durability and reliability of the fasteners, reducing equipment maintenance costs.
