Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular to a round pipe auxiliary welding device. Background Art

[0002] At present, the conventional practice for welding large round tubes is to use a lifting device to lift the large round tube and place it on a roller frame to build the basic conditions for subsequent welding operations. However, due to the large weight of the large round tube, the process of lifting and transferring will inevitably cause the initially formed weld to expand due to factors such as gravity pulling and unbalanced force. As the weld becomes larger, the original precise circular structure of the round tube is destroyed and it no longer maintains its standard circular profile.

[0003] This problem of round tube deformation caused by hoisting will trigger a series of chain reactions in the subsequent processing procedures. For example, during the subsequent pipe connection, assembly and fine processing, due to the deviation of the round tube shape, additional adjustment and correction procedures are required to compensate, which will undoubtedly consume more manpower, material resources and time resources.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1~Figure 3, which is the first embodiment of the present invention, proposes a round tube auxiliary welding device, including: a support frame 1 used to be set on the ground, the support frame 1 has a support gap 11, and the support gap 11 is used to support the round tube; a welding piece 2 is movably set on the ground, and after the welding piece 2 moves, it is used to weld the round tube; one end of the inclined plate 3 is set on the ground, and the other end is erected on the support frame 1, and the round tube enters the support gap 11 through the inclined plate 3; a pushing member 4 is movably set on the support frame 1, and the pushing member 4 is used to push the round tube out of the support gap 11.

[0024] In this embodiment, the support frame 1 is placed on the floor of the workshop to ensure its stability. The support gap 11 is used to place the round tube. The welding piece 2 is installed on the ground through a track or other mobile guide device so that it can move freely in the horizontal direction, so as to perform welding operations on the round tube in the support gap 11. One end of the inclined plate 3 is fixed at a suitable position on the ground, and the other end is placed on the support frame 1, and the inclination angle of the inclined plate 3 is to ensure that the round tube can smoothly roll in and out of the support gap 11 of the support frame 1 along the inclined plate 3 from the ground under the action of gravity. A push plate can be driven by a telescopic cylinder to push the large round tube through the inclined plate 3 into the support gap 11. The pusher 4 is installed on the support frame 1 and can move linearly along the support frame 1 under the drive of a power device (such as a cylinder, a screw nut mechanism, etc.). When the welding is completed, the pusher 4 moves to push the round tube out of the support gap 11, and the round tube rolls down to the ground along the inclined plate 3. When the round tube is pushed into the support gap 11 , the pusher 4 can receive the round tube to prevent the round tube support from falling into the support gap 11 .

[0025] The support gap 11 of the support frame 1 can provide a stable support foundation for welding, ensure that the position of the round pipe remains unchanged during welding, and improve welding accuracy. The setting of the inclined plate 3 facilitates the loading operation of the round pipe, and there is no need to hoist the round pipe to the support frame 1 with a hoisting member, which not only prevents the expansion of the round pipe weld, but also saves manpower and improves the loading speed. The pusher 4 facilitates the unloading of the round pipe after welding is completed, making the entire welding process more automated, reducing manual intervention, improving production efficiency and reducing labor intensity. The pusher 4 and the inclined plate 3 are used in combination. When loading, the pusher 4 receives the round pipe so that the round pipe can stably enter the support gap 11.

[0026] Furthermore, the mounting seat 12 is used to be set on the ground; the first L-shaped frame 13 is rotatably set on the mounting seat 12; the second L-shaped frame 14 is rotatably set on the mounting seat 12; there are four first rollers 15, and the four first rollers 15 are rotatably set on the first L-shaped frame 13 and the second L-shaped frame 14 in pairs, and the four first rollers 15 form a support gap 11.

[0027] In this embodiment, the mounting base 12 is first fixed on the ground to ensure its horizontality and stability. The right-angle end of the first L-shaped frame is mounted on the mounting base 12 through a rotating shaft so that it can rotate around the shaft, and a first roller 15 is installed at each of the other two ends of the first L-shaped frame. Similarly, the right-angle end of the second L-shaped frame is also mounted on the mounting base 12 through another rotating shaft, and two other first rollers 15 are correspondingly installed at the other two ends of the second L-shaped frame. The position relationship of the four first rollers 15 is such that they together form a circular support gap 11, and the round tube can be placed therein and roll on the rollers.

[0028] The rotation setting of the first L-shaped frame and the second L-shaped frame enables the support frame 1 to adapt to round tubes of different diameters. By adjusting the relative angle between the two, the size of the support gap 11 can be changed, thereby improving the compatibility of the device with round tubes of different specifications. The setting of the first roller 15 reduces the friction force of the round tube when it moves in the support gap 11, allowing the round tube to rotate, which is beneficial to the position adjustment of the round tube during the welding process, and also reduces the wear on the surface of the round tube, thereby improving the product quality.

[0029] Further, the first rotating shaft 5 is rotatably set on the mounting seat 12, the first L-shaped frame 13 is set on the first rotating shaft 5, and the first L-shaped frame 13 is rotatably set on the mounting seat 12 through the first rotating shaft 5; the second rotating shaft 6 is rotatably set on the mounting seat 12, the second L-shaped frame 14 is set on the second rotating shaft 6, and the second L-shaped frame 14 is rotatably set on the mounting seat 12 through the second rotating shaft 6; the transmission member 7 is set on the mounting seat 12, and after the first rotating shaft 5 rotates, the second rotating shaft 6 is driven to rotate through the transmission member 7.

[0030] In this embodiment, the first rotating shaft 5 and the second rotating shaft 6 are installed on the mounting seat 12 to ensure that they can rotate freely around their own axes, and the first L-shaped frame is fixed on the first rotating shaft 5, and the second L-shaped frame is fixed on the second rotating shaft 6. The transmission member 7 can be a gear transmission, a chain transmission or a belt transmission. For example, when a gear transmission is adopted, mutually meshing gears are respectively installed on the first rotating shaft 5 and the second rotating shaft 6. When the first rotating shaft 5 rotates under the drive of a motor or other power source, the second rotating shaft 6 is driven to rotate synchronously through the gear meshing; if a chain transmission is adopted, corresponding sprockets are installed on the first rotating shaft 5 and the second rotating shaft 6, and the chain is wrapped around the two sprockets. When the first rotating shaft 5 rotates, the chain drives the second rotating shaft 6 to rotate.

[0031] The first rotating shaft 5 and the second rotating shaft 6 are linked by the transmission member 7, so that the first L-shaped frame and the second L-shaped frame can adjust the angle synchronously, ensuring the symmetry and stability of the support gap 11 during the adjustment process, which is conducive to the precise positioning and stable support of the round tube. This linkage design simplifies the operation process. Only by controlling the rotation of one rotating shaft, the adjustment of the entire support frame 1 can be achieved, which improves the operation convenience and automation of the device.

[0032] Furthermore, the other end of the inclined plate 3 is used to be erected on the second L-shaped frame 14; the first bevel gear 8 is chain-drivenly arranged on the first rotating shaft 5; the third rotating shaft 9 is rotatably arranged on the mounting seat 12; the second bevel gear 10 is arranged on one end of the third rotating shaft 9, and the first bevel gear 8 and the second bevel gear 10 are meshed; the sliding frame 41 is slidably arranged on the mounting seat 12, and the sliding frame 41 is threadedly arranged on the other end of the third rotating shaft 9; the abutment 42 is rotatably and swingably arranged on the sliding frame 41, and the abutment 42 is used to abut the round tube in the support gap 11.

[0033] In this embodiment, the first bevel gear 8 is installed at a suitable position of the first rotating shaft 5, the third rotating shaft 9 is installed on the mounting seat 12 through a bearing, and the second bevel gear 10 meshing with the first bevel gear 8 is installed at one end of the third rotating shaft 9. The sliding frame 41 is installed on the mounting seat 12 through a guide rail or a slide groove, so that it can slide linearly on the mounting seat 12, and a thread is processed on the other end of the third rotating shaft 9, and a threaded hole matching it is set on the sliding frame 41, and the sliding frame 41 is threadedly connected with the third rotating shaft 9. After the round pipe welding is completed, the driving member drives the first rotating shaft 5 to rotate, the first rotating shaft 5 drives the first bevel gear 8 to rotate, and the first bevel gear 8 drives the second bevel gear 10 to rotate. After the second bevel gear 10 rotates, the sliding frame 41 drives the abutment member 42 to approach the round pipe and push the round pipe so that the round pipe is completely located on the second L-shaped frame 14. As the pusher 4 pushes and the second L-shaped frame 14 continues to rotate, the round pipe enters the inclined plate 3 and slides down along the inclined plate 3 to achieve automatic unloading. The swing frame 43 of the abutment 42 is installed on the sliding frame 41 by means of a pin shaft or the like, so that it can swing within a certain range. Two second rollers 44 are installed on the swing frame 43. When the sliding frame 41 moves driven by the second bevel gear 10, the abutment 42 can approach or move away from the circular tube in the support gap 11, contact the circular tube through the rollers and apply thrust or pulling force.

[0034] By utilizing the meshing transmission of the first bevel gear 8 and the second bevel gear 10, the rotational motion of the first rotating shaft 5 is converted into the rotational motion of the third rotating shaft 9, thereby driving the linear movement of the sliding frame 41, realizing the power transmission and motion conversion between the pusher 4 and the adjustment mechanism of the support frame 1, saving an additional power source, and making the device structure more compact. When the angle of the round pipe needs to be adjusted separately during the welding process, the first bevel gear 8 can be designed as a structure that slides on the first rotating shaft 5, so that the first bevel gear 8 is manually slid and the first bevel gear 8 and the second bevel gear 10 are no longer meshed.

[0035] Furthermore, the swing frame 43 is swingably disposed on the sliding frame 41 ; there are two second rollers 44 , which are rotatably disposed on the swing frame 43 , and the second rollers 44 are used to abut against the round tube.

[0036] In this embodiment, a suitable shaft hole or shaft seat is provided on the sliding frame 41, and the swing frame 43 is an L-shaped frame, and the right-angle end of the swing frame 43 is installed in it through a pin shaft, so that the swing frame 43 can swing around the pin shaft at a certain angle. Two second rollers 44 are installed at the other two ends of the swing frame 43, and the second rollers 44 are installed on the swing frame 43 through bearings to ensure that the second rollers 44 can rotate freely. After the second rollers 44 rotate, they can abut on both sides of the round tube to a greater extent.

[0037] The swing design of the swing frame 43 enables the abutment member 42 to better adapt to different positions of the round tube in the support gap 11. Even if the round tube is eccentric or tilted to a certain extent, the abutment position can be automatically adjusted by the swing of the swing frame 43 to ensure the effectiveness of the push. The provision of the two second rollers 44 further reduces the friction between the round tube and improves the pushing efficiency, while also reducing the impact on the surface quality of the round tube.

[0038] Furthermore, the fourth rotating shaft 110 is rotatably disposed on the second L-shaped frame 14 , and the first roller 15 is rotatably disposed on the fourth rotating shaft 110 ; the first chain 120 is cyclically transported on the second rotating shaft 6 and the fourth rotating shaft 110 .

[0039] In this embodiment, the fourth rotating shaft 110 is installed on the second L-shaped frame so that it can rotate around its own axis, and the first roller 15 is installed on the fourth rotating shaft 110 through a bearing. Sprockets are installed on the second rotating shaft 6 and the fourth rotating shaft 110 respectively, and the first chain 120 is wrapped around the two sprockets to ensure that the first chain 120 is properly tensioned. When the second rotating shaft 6 rotates, the fourth rotating shaft 110 is driven to rotate synchronously through the first chain 120. This transmission method has a simple structure, high reliability, easy maintenance and adjustment, and reduces the operating cost of the device.

[0040] Furthermore, one end of the inclined plate 3 is slidably disposed on the ground, and the other end of the inclined plate 3 has a mounting portion 31 , which is disposed on the fourth rotating shaft 110 , and the inclined plate 3 is tangent to the first roller 15 which is disposed concentrically with the mounting portion 31 .

[0041] In this embodiment, a guide rail or a slide groove is arranged on the ground, and one end of the inclined plate 3 is installed therein through a slider, so that it can slide linearly on the ground to adjust the inclination angle and position of the inclined plate 3. A mounting portion 31 is designed at the other end of the inclined plate 3, and the mounting portion 31 is connected to the fourth rotating shaft 110 through a key connection or other fixing methods, and the outer circumference of the first roller 15 concentrically arranged between the inclined plate 3 and the mounting portion 31 is ensured to be tangent. When loading and unloading, the first L-shaped frame 13 and the second L-shaped frame 14 rotate to drive the inclined plate 3 to swing. After the inclined plate 3 swings, it is more inclined, and the loading and unloading of the round tube is more convenient, and the drop of the round tube is smaller, so that the round tube can smoothly transition from the inclined plate 3 to the first roller 15 to reduce the impact.

[0042] The sliding setting at one end of the inclined plate 3 increases the adjustability of the inclined plate 3, and can flexibly adjust the feeding height and angle of the round tube according to actual production needs. The tangent design of the inclined plate 3 and the first roller 15 ensures the smoothness of the round tube feeding process, avoids surface damage or position deviation of the round tube caused by collision or jamming during feeding, and improves the feeding accuracy and reliability.

[0043] Furthermore, the second chain 130 is circulated and conveyed on the inclined plate 3; the movable plate 140 is set on the second chain 130, and the movable plate 140 is moved and set on the inclined plate 3 through the second chain 130. After the movable plate 140 moves to one end of the inclined plate 3, it is set parallel to the ground. After the movable plate 140 moves to the other end of the inclined plate 3, it is set perpendicular to the inclined plate 3.

[0044] In this embodiment, sprockets are installed on both sides of the inclined plate 3, the second chain 130 is wound around the sprockets to form a circulating conveying structure, and the moving plate 140 is fixed on the second chain 130. When the second chain 130 rotates under the drive of the motor or other power source, the moving plate 140 moves on the inclined plate 3 along with the chain. By controlling the movement direction and speed of the chain, the moving plate 140 is in a horizontal state when it is at one end of the inclined plate 3, so that the round tube is placed thereon conveniently. When the moving plate 140 moves to the other end of the inclined plate 3, it automatically flips to a vertical state with the inclined plate 3, and guides the round tube onto the first roller 15 in the support gap 11.

[0045] The circular movement design of the moving plate 140 on the inclined plate 3 realizes the automatic feeding function of the round tubes, and there is no need to manually place the round tubes one by one on the inclined plate 3, which improves the feeding efficiency and reduces the labor intensity. The different posture conversions of the moving plate 140 at both ends of the inclined plate 3 ensure the stability of the round tubes during the feeding process, avoid the round tubes from slipping or getting stuck when rolling on the inclined plate 3, and improve the safety and reliability of the production process.

[0046] Furthermore, the third chain 150 is cyclically transported on the fourth rotating shaft 110 and the other end of the inclined plate 3 , and the third chain 150 drives the first chain 120 and the second chain 130 to move synchronously.

[0047] In this embodiment, sprockets are installed on the fourth rotating shaft 110 and the other end of the inclined plate 3, respectively, and the third chain 150 is wrapped around the two sprockets, and the third chain 150 is connected to the first chain 120 and the second chain 130 through a chain connector, so that they can work together. When welding the round tube, only the angle of the round tube is adjusted, and the round tube will not be accidentally cut. In this embodiment, the first chain 120 can be removed, and after the welding is completed, the first chain 120 can be manually reinstalled. When the first chain 120 rotates under the power drive, it drives the third chain 150 and the second chain 130 to rotate synchronously, realizing the rotation of the first roller 15 on the support frame 1, the movement of the moving plate 140 on the inclined plate 3, and the orderly transmission and processing of the round tube in the entire device.

[0048] The third chain 150 realizes the linkage control of multiple key components in the whole device, so that the movement between the components is coordinated and consistent, and the overall operation stability and reliability of the device are improved. By driving multiple components to move through a power chain, the power system structure of the device is simplified, the equipment cost and maintenance difficulty are reduced, and the automation control and programming operation of the whole welding device are also facilitated.

[0049] Reference Figure 4~Figure 5 , which is the first embodiment of the present invention, further, the frame 170 is lifted and lowered on the base 160 , and the welding piece 2 is slidably disposed on the frame 170 .

[0050] In this embodiment, the base 160 is fixed to the workshop floor by means of anchor bolts, etc., a lifting mechanism such as a screw lift, a hydraulic lift, etc. is installed on the base 160, the frame 170 is installed at the moving end of the lifting mechanism, and the frame 170 is lifted and lowered by the action of the lifting mechanism. A guide rail or a slide rail is installed on the frame 170, and the weldment 2 is installed on the frame 170 through a slider, so that the weldment 2 can slide horizontally on the frame 170, and welding equipment such as a welding power source and a welding gun are installed on the weldment 2.

[0051] The lifting arrangement of the frame 170 enables the welding piece 2 to adapt to the welding requirements of round pipes of different diameters and heights. By adjusting the height of the frame 170, the welding gun of the welding piece 2 can be placed in the best welding position. The sliding design of the welding piece 2 on the frame 170 further expands the working range of the welding piece 2, enabling it to perform welding operations in the axial direction of the round pipe, realizing all-round welding of the round pipe, and improving the welding quality and efficiency.

[0052] Working process: After the round tube is bent into a cylindrical shape, it is pushed onto the horizontal movable plate 140. At this time, the two first rollers 15 on the first L-shaped plate face the round tube. As the driving member drives the first L-shaped frame 13 and the second L-shaped frame 14 to rotate, the transmission member 7, the first chain 120, and the third chain 150 work together to drive the second chain 130 to move. After the second chain 130 moves, it first drives the movable plate 140 to swing. After the swing, it ensures that the round tube is stuck between the movable plate 140 and the inclined plate 3. The second chain 130 continues to move. The moving plate 140 moves upward along the inclined plate 3. With the action of the first chain 120, the inclination angle of the inclined plate 3 is gradually increased. After the moving plate 140 drives the round tube to move to the other end of the inclined plate 3, the round tube is completely supported on the second L-shaped plate. At this time, the second roller 44 of the abutment 42 just contacts the round tube. With the continued driving of the driving member, the second roller 44 acts on the round tube, so that the round tube is slowly clamped in the support gap 11, until the second roller 44 is disengaged from the round tube, and the round tube is clamped in the support gap 11. After welding is completed, the driving member drives the first rotating shaft 5 to rotate, the first bevel gear 8 drives the second bevel gear 10 to rotate, and the sliding frame 41 drives the second roller 44 on the swing plate to approach the round tube. After the first rotating shaft 5 continues to rotate, the second rotating shaft 6 is driven to rotate through the transmission member 7, and the first L-shaped frame 13 and the second L-shaped frame 14 lift the round tube together. After lifting to the highest position, the second roller 44 contacts the round tube and pushes the round tube in the direction of the second plate, and pushes the round tube onto the second L-shaped plate. Since the round tube is heavy, in order to ensure that the round tube can roll down along the inclined plate 3 smoothly, this scheme can design a telescopic cylinder and a support plate on the mounting seat 12. After the first L-shaped frame 13 and the second L-shaped frame 14 lift the round tube to the highest position together, the telescopic cylinder is extended to drive the support plate to lift the round tube, so that the second roller 44 can push the round tube in the direction of the second L-shaped plate. As the first L-shaped plate and the second L-shaped plate continue to rotate, the round tube is guided by the second L-shaped plate and rolls onto the inclined plate 3, and the moving plate 140 drives the round tube to slowly roll down to the ground. It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
