Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically to a workbench for pipeline welding. Background Technology

[0002] In pipeline engineering, pipe welding is a key process for connecting pipes and constructing complex pipeline systems. To ensure welding quality and the safety of the pipeline system, the welding process requires precise control and stable operation. During the welding process, pipe clamps are widely used as an important auxiliary tool to fix and support pipes, ensuring that the pipes remain stable during welding and avoiding displacement or deformation caused by external forces.

[0003] Traditional welding workbenches typically use clamps to hold pipes and workpieces in place. However, traditional clamps are often only suitable for workpieces of specific shapes and sizes. For pipes with complex shapes or varying sizes, they are difficult to hold effectively, causing the workpiece to loosen during welding, which affects welding quality and precision. Furthermore, the machining angle of traditional workbenches is usually fixed, making it difficult to flexibly adjust the angle of the workpiece according to welding requirements. This forces welders to frequently move the workpiece or adjust the welding equipment when welding at different positions, which is extremely inconvenient and seriously affects welding efficiency and quality. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a workbench for pipe welding, which solves the technical problem that traditional fixtures in related technologies / existing technologies can only adapt to workpieces of specific shapes and sizes, and it is difficult to achieve effective fixation for pipe workpieces with complex shapes or variable sizes.

[0005] The device includes a base, a processing table rotatably connected to the upper surface of the base, a mounting bracket fixedly connected to the upper surface of the base, a welding equipment body fixedly mounted on the surface of the mounting bracket, a workpiece body on the surface of the processing table, a motor on the surface of the processing table, a bidirectional lead screw fixedly connected to the output end of the motor, movable sleeves threaded to both ends of the bidirectional lead screw, movable plates fixedly connected to the surface of the movable sleeves, a backing plate fixedly connected to the surface of one movable plate, an arc-shaped support plate and an assembly base fixedly connected to the surface of the other movable plate, a sliding plate slidably connected to the inner wall of the assembly base, a locking rod fixedly connected to the lower surface of the sliding plate, a telescopic spring abutting the upper surface of the sliding plate, a force-bearing rod fixedly connected to the upper surface of the sliding plate, an embedded block fixedly connected to the surface of the arc-shaped support plate, and a rotating mechanism for adjusting the processing angle of the processing table on the surface of the base.

[0006] The above technical solution avoids the traditional operation of manually holding the workpiece for welding, improving the safety and stability of welding. The arc-shaped support plate can be flexibly replaced, and the backing plate is large and does not need to be replaced, allowing personnel to clamp workpieces of different sizes, ensuring clamping and welding effects. The quick-assembly and disassembly design allows personnel to flexibly change clamping components according to different workpiece sizes, improving work efficiency. The angle of the processing table can be adjusted by rotating the mechanism, thereby adjusting the angle of the workpiece, allowing personnel to quickly weld different positions on the workpiece, improving the flexibility and convenience of welding.

[0007] As a further improvement to the above solution, the rotating mechanism includes an annular slide groove, a second motor is fixedly connected inside the annular slide groove, a load-bearing plate is fixedly connected to the output end of the second motor, and several rotating rods are fixedly connected to the lower surface of the load-bearing plate.

[0008] Through the above technical solution, the cooperation between the annular slide and the rotating rod makes the rotation of the processing table more stable and reliable, ensuring the stability of the workpiece body during the welding process and helping to improve the welding quality.

[0009] As a further improvement to the above solution, one side of the workpiece body is in contact with the backing plate, and the other side of the workpiece body is in contact with the arc-shaped support plate.

[0010] With the above technical solution, the backing plate and the arc-shaped support plate contact the square side and the arc-shaped side of the workpiece body respectively, which can apply clamping force to the workpiece body from different directions, ensuring that the workpiece body is firmly fixed on the processing table, preventing the workpiece body from shifting during the welding process, thereby ensuring the accuracy and quality of welding.

[0011] As a further improvement to the above solution, the surface of the embedded block is provided with positioning holes, and the surface of the movable plate below the assembly base is provided with cavities.

[0012] As a further improvement to the above solution, the cavity is adapted to the embedded block, and the positioning hole is adapted to the locking rod.

[0013] As a further improvement to the above solution, limit crossbars penetrate both sides of the outer surface of the movable screw sleeve, and a protective shell is fixedly connected to the upper surface of the processing table.

[0014] As a further improvement to the above solution, the motor is fixedly connected to the inner wall of the protective shell, the limiting crossbar is fixedly connected to the inner wall of the protective shell, and the bidirectional lead screw is rotatably connected to the inner wall of the protective shell.

[0015] As a further improvement to the above solution, the load-bearing plate is fixedly connected to the middle of the lower surface of the processing table, and the rotating rod is slidably connected to the inside of the annular groove.

[0016] The beneficial effects of this utility model are as follows: This invention uses a backing plate and an arc-shaped support plate to clamp the square and arc-shaped sides of the workpiece body respectively, ensuring that the workpiece is firmly fixed on the processing table. Furthermore, the arc-shaped support plate can be quickly disassembled and replaced. Pulling the force rod allows for quick unlocking and locking of the locking rod and positioning hole, adapting to workpieces of different sizes and avoiding the hassle of frequently replacing the entire clamping device due to changes in workpiece size, thus improving work efficiency. The angle of the processing table can be adjusted via a rotating mechanism within the base. Motor 2 drives the load-bearing plate and rotating rod to rotate within the annular groove, enabling flexible rotation of the processing table. This avoids the inconvenience of welding operations caused by a fixed workpiece angle, allowing welders to quickly weld different positions on the workpiece, further enhancing the flexibility and convenience of welding.

[0025] like Figures 1-5The diagram illustrates a pipe welding workbench according to an embodiment of the present invention, comprising a base 1, a processing table 2 rotatably connected to the upper surface of the base 1, a mounting bracket 3 fixedly connected to the upper surface of the base 1, a welding equipment body 4 fixedly mounted on the surface of the mounting bracket 3, a workpiece body 5 disposed on the surface of the processing table 2, a motor 6 disposed on the surface of the processing table 2, a bidirectional lead screw 7 fixedly connected to the output end of the motor 6, movable sleeves 8 threadedly connected to both ends of the bidirectional lead screw 7, movable plates 9 fixedly connected to the surface of the movable sleeves 8, and a backing plate fixedly connected to the surface of one of the movable plates 9. 10. Another movable plate 9 has an arc-shaped support plate 11 and an assembly base 12 fixedly connected to its surface. The inner wall of the assembly base 12 is slidably connected to a sliding plate 13. A locking rod 14 is fixedly connected to the lower surface of the sliding plate 13. A telescopic spring 15 abuts against the upper surface of the sliding plate 13. A force-bearing rod 16 is fixedly connected to the upper surface of the sliding plate 13. An embedded block 17 is fixedly connected to the surface of the arc-shaped support plate 11. The surface of the base 1 is provided with a rotating mechanism for adjusting the processing angle of the processing table 2. The workpiece body 5 consists of an arc-shaped part and a square part, and the square part and the arc-shaped part have been externally spot-welded together. First, the operator places the workpiece body 5, composed of curved and square parts, in the center of the processing table 2. Then, the motor 6 is started, and its output bidirectional lead screw 7 rotates, causing the movable sleeves 8 on both sides to move the movable plates 9 synchronously towards the center. The support plate 10 and the curved support plate 11 then move towards the center. The support plate 10 pushes the square side of the workpiece body 5, and the curved support plate 11 pushes the curved side of the workpiece body 5, fixing the workpiece body 5 onto the processing table 2. During welding, the welding equipment body 4 can be connected to an external robotic arm for multi-directional welding. The curved support plate 11 can be flexibly replaced and disassembled according to the size of the workpiece body 5. When the force rod 16 is pulled upward, the sliding plate 13 rises and compresses the telescopic spring 15, the locking rod 14 disengages from the embedded block 17, unlocking the embedded block 17, so that the arc-shaped support plate 11 can be separated from the movable plate 9 below the assembly base 12; during installation, the force rod 16 is pulled to retract the locking rod 14, inserting the embedded block 17 into the movable plate 9, the force rod 16 is released, the locking rod 14 descends and inserts into the embedded block 17, locking the embedded block 17. During the welding process, the angle of the processing table 2 can be adjusted by the rotation mechanism inside the base 1, thereby adjusting the angle of the workpiece body 5, which facilitates welding at different positions of the workpiece body 5.

[0026] In some examples, the rotating mechanism includes an annular slide 22, with a motor 23 fixedly connected inside the annular slide 22. A load-bearing plate 24 is fixedly connected to the output end of the motor 23. Several rotating rods 25 are fixedly connected to the lower surface of the load-bearing plate 24. When the motor 23 starts, it drives the load-bearing plate 24 to rotate. The load-bearing plate 24 slides in the annular slide 22 through the rotating rods 25, thereby driving the processing table 2 to rotate and realize the adjustment of the angle of the processing table 2.

[0027] Furthermore, one side of the workpiece body 5 is in contact with the backing plate 10, and the other side of the workpiece body 5 is in contact with the arc-shaped support plate 11. When the workpiece body 5 is placed on the processing table 2, one side of it is in contact with the backing plate 10, and the other side is in contact with the arc-shaped support plate 11. The backing plate 10 and the arc-shaped support plate 11 cooperate with each other to fix the workpiece body 5 on the surface of the processing table 2.

[0028] refer to Figure 4 The surface of the embedded block 17 is provided with positioning holes 18, and the surface of the movable plate 9 below the assembly base 12 is provided with a cavity 19.

[0029] Furthermore, the cavity 19 is adapted to the embedded block 17, and the positioning hole 18 is adapted to the locking rod 14.

[0030] Furthermore, limit crossbars 20 are passed through both sides of the outer surface of the movable screw sleeve 8, and a protective shell 21 is fixedly connected to the upper surface of the processing table 2. The limit crossbars 20 limit the movement of the movable screw sleeve 8, preventing the movable screw sleeve 8 from deviating or shaking when the bidirectional screw 7 rotates, and ensuring that the movable screw sleeve 8 can drive the movable plate 9 to move smoothly and accurately.

[0031] like Figure 3 As shown, motor 6 is fixedly connected to the inner wall of protective shell 21, limit crossbar 20 is fixedly connected to the inner wall of protective shell 21, and bidirectional lead screw 7 is rotatably connected to the inner wall of protective shell 21.

[0032] Furthermore, the load-bearing plate 24 is fixedly connected to the middle of the lower surface of the processing table 2, and the rotating rod 25 is slidably connected to the inside of the annular groove 22.

[0033] In this embodiment, firstly, the workpiece body 5, composed of an arc-shaped part and a square part, is placed in the middle of the processing table 2. The square side of the workpiece body 5 is in contact with the backing plate 10, and the arc-shaped side is in contact with the arc-shaped support plate 11. The motor 6 is started, and the bidirectional lead screw 7 at its output end begins to rotate. Since the threads at both ends of the bidirectional lead screw 7 are opposite, the movable sleeves 8 on both sides will move towards the middle synchronously. The movable sleeves 8 drive the movable plate 9 to move towards the middle, thereby pushing the backing plate 10 and the arc-shaped support plate 11 closer to the workpiece body 5. The backing plate 10 pushes the square side of the workpiece body 5, and the arc-shaped support plate 11 pushes the arc-shaped side of the workpiece body 5. Finally, the workpiece body 5 is firmly fixed on the processing table 2 to ensure that the workpiece will not be displaced during the welding process.

[0034] Secondly, when it is necessary to replace the arc-shaped support plate 11 to accommodate workpieces 5 of different sizes, pull the force rod 16 upward. The force rod 16 drives the sliding plate 13 to rise, while squeezing the telescopic spring 15. As the sliding plate 13 rises, the locking rod 14 disengages from the positioning hole 18 in the embedded block 17, unlocking the embedded block 17. At this time, the arc-shaped support plate 11 can be separated from the movable plate 9 below the assembly base 12 through the embedded block 17 on its surface. When replacing the new arc-shaped support plate 11, pull the force rod 16 again to retract the locking rod 14 into the assembly base 12. Insert the embedded block 17 of the new arc-shaped support plate 11 into the cavity 19 of the movable plate 9. Release the force rod 16, and the locking rod 14 descends under the elastic force of the telescopic spring 15 and inserts into the positioning hole 18 of the embedded block 17, completing the quick installation of the arc-shaped support plate 11.

[0035] During the welding process, the welding equipment body 4 can be connected to an external robotic arm to achieve multi-directional welding operations. At the same time, the angle of the processing table 2 can be flexibly adjusted through the rotating mechanism inside the base 1, thereby adjusting the angle of the workpiece body 5. When the motor 23 starts, the load-bearing plate 24 at its output end begins to rotate. The rotating rod 25 on the lower surface of the load-bearing plate 24 slides in the annular groove 22, driving the processing table 2 to rotate around the central axis of the base 1, so that the welding personnel can quickly weld different positions of the workpiece body 5.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
