Description

Technical Field

[0001] This invention belongs to the field of automatic welding of cylindrical circumferential seams, specifically an automatic welding device for cylindrical circumferential seams. Background Technology

[0002] The welding of the circumferential seam of the cylinder is mostly done manually. In fact, if the cylinder is too large, various large tools and fixtures are required for manual welding. Although the quality of manual welding is generally better because it can be evaluated, it requires skilled workers. Moreover, the handling and alignment of the cylinder requires the participation of crane operators and dispatchers, which makes it impossible to reduce the number of personnel involved, resulting in extremely high costs. The cylinder itself is prone to rolling and its large weight makes alignment difficult and also poses a great danger. Therefore, an automatic welding device for the circumferential seam of the cylinder is proposed. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given the following technical problems in the existing technology: the handling and alignment of the cylinder requires the participation of cranes and command and dispatch personnel, which makes it impossible to reduce the number of personnel involved, resulting in extremely high costs; the cylinder itself is prone to rolling and has a large mass, making alignment difficult and posing a significant danger.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic welding device for cylindrical circumferential seams, including a receiving seat, a vertical arm mounted on the top of the receiving seat, and a movable vertical arm one and a movable vertical arm two mounted on the top of the receiving seat, the movable vertical arm one and the movable vertical arm two being distributed on both sides of the vertical arm, and assembly pieces mounted on the movable vertical arm one, the movable vertical arm two and the vertical arm, and clamping components mounted on the assembly pieces;

[0006] The head of the receiving seat is recessed with a movable groove, a connecting seat is installed on the lower side of the movable vertical arm, and a connecting seat is installed on the lower side of the movable vertical arm. Both the connecting seat and the connecting seat are movably connected to the movable groove.

[0007] A movable component is installed on one side of the receiving seat. The movable component includes a motor five. The power rod of the motor five is connected to a lead screw three. The lead screw three is connected to the movable seat. A long plate is fixedly connected to the movable seat. A movable groove three is recessed on the inner side of the receiving seat. The movable seat is movably connected within the movable groove three.

[0008] Activity Ditch Road 1 is the upper half of Activity Ditch Road 3.

[0009] The long piece is connected to the first connecting seat using a constraint component, and the long piece is fixedly connected to the second connecting seat;

[0010] Rotating components are installed on the inner sides of connecting seat 2 and connecting seat 1. The rotating components can deflect the movable vertical arm 2 by an arc of π / 2 when the movable vertical arm 2 moves.

[0011] As a preferred technical solution for an automatic welding device for cylindrical circumferential seams, the battery supplies power to the welding components to weld the cylindrical body. The motor drives the lead screw to rotate, causing the movable seat to move along the movable groove under the constraint of the movable groove. The movable seat moves away from the connecting seat 2, and the standing surface of the pressure seat contacts the standing surface of the lower cavity. The movable seat pulls the long plate to move, and the long plate uses the pressure seat to press the connecting seat 1 to move, and drives the connecting seat 2 to move together.

[0012] During the movement of the second connecting seat, the second connecting seat moves the first toothed plate, causing the toothed plate and the first connecting plate to engage during the engagement of the transmission teeth. During this period, the transmission teeth rotate. During this period, the first toothed plate moves the second movable vertical arm.

[0013] As a preferred technical solution for an automatic welding device for cylindrical circumferential seams, the movable vertical arm can carry the cylindrical body clamped by the clamping component to correspond and dock with another cylindrical body to be welded;

[0014] Motor 4 on movable vertical arm 2 starts. Motor 4 is fixedly connected to lead screw 5 through connecting parts. Lead screw 5 is connected to control seat. Lead screw 5 drives control seat to move. Control seat controls assembly piece to swing with clamp 1 and clamp 2, so that clamp 1 and clamp 2 move closer or further away.

[0015] The connecting seat moves along with the movable vertical arm, which in turn moves along with the cylinder clamped by the clamping component.

[0016] As a preferred technical solution for an automatic welding device for cylindrical circumferential seams, motor five can also drive screw three to rotate, causing the movable seat to return to its original position. The movable seat drives screw three to return to its original position, and the movable seat returns to its original position along with the long plate, which in turn brings the pressure seat back to its original position. The sloping wall of the pressure seat presses against the lower cavity, causing the pressure seat to move downward. The C-shaped spring plate contracts under force, causing the connecting seat one to pause at the starting point. The movable vertical arm one connected to the connecting seat one also pauses at the starting point.

[0017] During the return of the long plate to its original position, the long plate will lift the connecting seat 2 back to its original position. The connecting seat 2 drives the toothed plate 1 back to its original position. During the engagement of the toothed plates, the toothed plate 1 rotates in another direction.

The pressure seat is above the welding component, and the pressure seat is movably engaged with the lower cavity, so that the pressure seat can move with the connecting seat two.

[0023] When the pressure seat moves away from the connecting seat, the component of the force applied by the sloped wall in the horizontal direction to the lower cavity squeezes the pressure seat into the fixing pit, causing the C-shaped spring plate to deform and completely detach the pressure seat from the lower cavity.

An assembly piece 19 is mounted on the movable vertical arm 16, the movable vertical arm 2 18 and the vertical arm 17. A clamping component is mounted on the assembly piece 19.

[0058] The head of the receiving seat 12 is recessed with a movable groove 13, the lower side of the movable vertical arm 16 is provided with a connecting seat 14, and the lower side of the movable vertical arm 18 is provided with a connecting seat 22. The connecting seat 14 and the connecting seat 22 are both movably connected to the movable groove 13.

[0059] A movable component is installed on one side of the receiving seat 12. The movable component includes a motor 25. The power rod of the motor 25 is connected to a lead screw 26. The lead screw 26 is connected to a movable seat 27. A long piece 28 is fixedly connected to the movable seat 27. A movable groove 20 is recessed on the inner side of the receiving seat 12. The movable seat 27 is movably connected within the movable groove 20.

[0060] The long piece 28 is connected to the first connector 14 by a constraint component, and the long piece 28 is fixedly connected to the second connector 22;

[0061] A rotating component is installed on the inner side of the connecting seat 22 and the connecting seat 14. The rotating component can deflect the movable vertical arm 18 by an arc of π / 2 when the movable vertical arm 18 moves.

[0062] As a preferred technical solution for an automatic welding device for cylindrical circumferential seams, the battery 236 supplies electrical energy to the welding component 23 so that the welding component 23 welds the cylindrical body. The motor 25 drives the lead screw 26 to rotate, so that the movable seat 27 moves along the movable groove 20 under the constraint of the movable groove 20. The movable seat 27 moves away from the connecting seat 22, and the standing surface of the pressure seat 31 contacts the standing surface of the lower cavity 38. The movable seat 27 pulls the long plate 28 to move. The long plate 28 uses the pressure seat 31 to press the connecting seat 14 to move, and drives the connecting seat 22 to move together.

[0063] During the movement of the connecting seat 22, the connecting seat 22 moves the toothed plate 21, causing the toothed plate 21 to mesh with the transmission tooth 30 of the connecting piece 24. During this period, the transmission tooth 30 rotates. During this period, the toothed plate 21 swings with the movable vertical arm 2 18.

[0064] The movable vertical arm 218 can clamp the cylinder with the clamping component and align and connect with another cylinder to be welded;

[0065] The motor 4 35 on the movable vertical arm 2 18 starts. The motor 4 35 is fixedly connected to the lead screw 5 37 through the connector.

The control seat 36 controls the assembly piece 19 to swing with the clamp 1 40 and the clamp 2 41, so that the clamp 1 40 and the clamp 2 41 move closer or further apart.

[0066] The connecting seat 14 moves with the movable vertical arm 16, and the movable vertical arm 16 moves with the cylinder clamped by the clamping component.

Pressure seat 31 moves downward, and C-shaped spring plate 34 is compressed by force, causing connecting seat 14 to pause at the starting point. Movable vertical arm 16 connected to connecting seat 14 also pauses at the starting point.

[0068] During the return of the long plate 28 to its original position, the long plate 28 will lift the connecting seat 22 back to its original position. The connecting seat 22 drives the gear plate 21 to return to its original position. During the engagement of the gear plate 21 and the transmission gear 30, the gear plate 21 rotates in another direction. The gear plate 21 swings with the movable vertical arm 218. The motor 435 rotates the lead screw 537. The lead screw 537 controls the assembly plate 19 to separate, so that the clamping plate 40 clamps the cylinder.

[0069] The restraint components include a pressure seat 31, a sloping wall 32, a fixing pit 33, a C-shaped spring plate 34, and a lower cavity 38;

[0073] The pressure seat 31 moves toward the connecting seat 22. The pressure seat 31 is on the welding component 23. The pressure seat 31 is movably engaged with the lower cavity 38, so that the pressure seat 31 can move with the connecting seat 22.

[0074] When the pressure seat 31 moves away from the connecting seat 22, the component of the force applied by the slope wall 32 in the horizontal direction to the lower cavity 38 squeezes the pressure seat 31 into the fixing pit 33, causing the C-shaped spring plate 34 to deform, so that the pressure seat 31 is completely separated from the lower cavity 38.

The toothed plate 21 engages with the transmission tooth 30 of the connecting plate 24. The transmission tooth 30 is in a locked position. The rotation of the toothed plate 21 causes the movable vertical arm 2 18 to swing. The number of toothed plates 21 is four times that of the transmission tooth 30.

[0078] A welding component 23 is installed on the upper side of the receiving seat 12. The vertical arm 17 and the movable vertical arm 28 are distributed on both sides of the welding component 23. The welding component 23 includes a motor 232, a toothed plate 233, a gear ring 234, an adjusting component 235, a battery 236, a receiving component 237, a receiving frame 238, a constraint wheel 239, and a circular groove 2310.

[0086] The lower and upper threads of the lead screw 37 have different directions of rotation and are each connected to a control seat 36.

[0087] After the cylinder is clamped, motor 4 35 starts and drives lead screw 5 37 to rotate. The forward and reverse rotation of lead screw 5 37 causes the two control seats 36 to approach or move away from each other. The control seats 36, along with the assembly plate 19, approach or move away from each other. The assembly plate 19, along with the clamping plate 1 40 and the clamping plate 2 41, clamps or releases the cylinder.

[0088] The clamping plates 40 and 41 are staggered, and the clamping plates 40 and 41 are close to each other to clamp the cylinder;

[0089] The receiving arm 2354 has a pre-reserved mating groove on the side facing the receiving arm 2354. The orientation of the mating groove can prevent the receiving arm 2354 and the receiving frame 238 from interfering with each other.

[0090] The receiving arm 2354 rotates with the gear ring 234, causing the welding head to weld around the cylinder. The orientation of the mating groove can prevent the receiving arm 2354 and the receiving frame 238 from contacting each other.

[0091] The specific implementation method is as follows: the motor 35 on the movable vertical arm 16 and the vertical arm 17 moves the control seat 36 and the assembly piece 19 closer or further away through the lead screw 37. The assembly piece 19, along with the clamping pieces 41 and 40, moves closer to clamp one cylinder. The motor 35 on the movable vertical arm 18 moves the control seat 36 and the assembly piece 19 closer or further away through the lead screw 37. The assembly piece 19, along with the clamping pieces 41 and 40, moves closer to clamp another cylinder. The gear plate 21 controls the movable vertical arm 18 to stand up, so that the two cylinders are connected. The two cylinders are welded together by the welding components.

[0092] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project.
