Description

Technical Field

[0001] The present invention belongs to the technical field of container processing, and in particular relates to a container production welding device. Background Art

[0002] A container is a standardized, large-scale, reusable cargo transportation container, which is widely used in sea, railway and road transportation. Its design purpose is to ensure that goods can be standardized, convenient and safe during global transportation. The structure of a container is usually made of metal materials (such as steel or aluminum). Therefore, during its production and processing, welding technology is required to connect and fix each component. During the welding process, it usually includes the welding between the bottom frame, the top frame and the side plates, as well as the welding between the bottom frame, the top frame and the bottom plate and the top plate.

[0003] However, when traditional welding equipment welds between the bottom frame, the top frame and the side plates of a container, the following technical problems often exist: 1. It is impossible to realize continuous welding of the welding gun between the bottom frame and the four side plates and the top frame. After welding one side plate, it is necessary to manually adjust the position of the welding gun, reposition it and then weld the next side plate. This process not only consumes a lot of time, reduces the welding efficiency, but also frequent manual intervention easily leads to welding position deviation and affects the stability of welding quality; 2. The welding current and welding speed usually need to be manually adjusted according to experience. The technical levels of different operators vary greatly, making it difficult to accurately match the welding parameters with the requirements of different welding positions and materials. For example, when welding the bottom frame and the side plates, due to the gravity effect, the welding speed and current need to be reasonably controlled to ensure good weld formation; while when welding the top frame and the side plates, in order to prevent the molten pool from sinking, the welding parameters need to be changed accordingly, but it is very difficult for traditional equipment to achieve such accurate and automatic adjustment. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems raised in the above background art, and provide a container production welding device that can continuously weld four side plates to the bottom frame or the top frame by a welding gun, improving the continuity of the container during the welding process.

[0009] Preferably, a suction groove is opened on the side wall of the suction cup. The suction groove is communicated with an air pump arranged inside the suction cup.

[0010] Preferably, an adjusting motor for controlling the swinging angle of the adjusting rod is fixedly connected to the hinge seat.

The two electromagnets repel each other with the same poles. The second sliding rheostat is electrically connected to the two electromagnets.

[0014] Compared with the existing technology, the advantages of this container production welding equipment are as follows: 1. By setting the circumferential welding mechanism, during the production process of the container, the rotating rod can be driven to perform circumferential movement along the circumferential chute, thereby driving the mounting plate and the welding gun to perform circumferential movement, enabling the welding gun to continuously weld the four side plates to the bottom frame or the top frame, improving the continuity of the container during the welding process, and thus improving the welding efficiency and the production efficiency of the container.

[0015] 2. By setting the clamping mechanism, before welding, the clamping plates move closer to each other along the two fixed screw rods to clamp and fix the bottom frame. The top frame is clamped and fixed by the electric gripper. Subsequently, the electric gripper is lowered to the designated welding position by the long-range electric telescopic rod. The side plates are adsorbed and fixed by the suction cups, and the side plates are transported to the designated welding position, that is, the position where the side plates are in contact with the bottom frame and the top frame, through the short-range electric telescopic rod. Thus, the clamping and positioning work of each component of the container before welding can be completed without manual operation by the staff, with a high degree of automation.

[0016] 3. By setting the adjusting mechanism, after the welding between the bottom frame and each side plate is completed, the adjusting rod can be swung by the adjusting motor, changing the state of the adjusting rod from downward inclination to upward inclination, so that the welding gun can continue to weld between the top frame and each side plate, further improving the continuity of the welding work.

[0017] 4. By setting the control mechanism, during the process of adjusting the welding position, the change in the inclination state of the adjusting rod will cause the force analysis of the counterweight block in the adjusting cavity to change. When the adjusting rod inclines downward, driving the welding gun to weld the bottom frame and the side plates in a downward inclination, the welding current of the welding gun is relatively large, and at the same time, the driving motor drives the rotating rod at a relatively fast speed, accelerating the welding speed and having a higher welding efficiency. When the adjusting rod inclines upward, driving the welding gun to weld the top frame and the side plates in an upward inclination, the current in the circuit where the welding gun and the driving motor are located is relatively small, the welding current of the welding gun is relatively small, and the speed of the welding gun during circumferential movement is relatively slow to ensure the stability of the molten pool and avoid the sinking of the molten pool and uneven weld seams.

[0018] 5. By setting the towing rope, when the inclination state of the adjusting rod changes, the position change of the counterweight block in the adjusting cavity will drive the adjusting roller to rotate through the towing rope, so that the adjusting roller can drive the welding gun to perform a certain range of angle adjustment. The angle of the adjusted welding gun is symmetrically arranged with respect to the horizontal line compared with the angle of the welding gun before adjustment, ensuring the accuracy of the welding position.

[0019] 6. By setting the extension mechanism, during the circumferential movement of the mounting plate, when the mounting plate moves to the corner of the circumferential guide rail, the welding gun moves to the included angle position between the two side plates. At this time, the protruding position on the guide block pushes the guide wheel to move along the strip-shaped groove, increasing the magnetic repulsion force between the two electromagnets, enabling the sliding part to displace relative to the fixed part, and inserting the welding gun into the included angle position between the two side plates to improve the welding effect on the included angle position.

Specific embodiments

[0022] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] Embodiment: Refer to Figures 1 to 6 , a container production welding device, including: The workbench 1, as the basic support structure of the entire device, provides a platform for the installation and operation of other components. A welding platform 11 is fixedly connected to its upper end. The welding platform 11 is used to carry the container components to be welded, ensuring the stability of the components during the welding process. A welding gun 12 is movably installed on the welding platform 11. As a key component directly performing the welding operation, the welding gun 12 can move flexibly on the welding platform 11 to complete the welding work of each component of the container; The clamping mechanism 2 is used to clamp and fix the bottom frame, top frame and side plates before welding, ensuring the accurate position of each component during welding and avoiding displacement during the welding process, which may affect the welding quality. The clamping mechanism 2 includes a first fixing component 21, a second fixing component 22 and a third fixing component 23.

[0024] The first fixing component 21 includes two fixing grooves 211 symmetrically opened at the upper end of the welding platform 11. A fixing screw is rotatably connected in the fixing groove 211. A fixing motor for driving the fixing screw is provided in the welding platform 11. A clamping plate 212 is threadedly connected to the fixing screw. The clamping plate 212 is slidably connected to the inner wall of the fixing groove 211. After the fixing motor is started, it drives the fixing screw to rotate, and the clamping plate 212 moves closer to or away from each other along the two fixing screws, so as to realize the clamping and fixing of the bottom frame.

[0025] The second fixing component 22 includes a plurality of support plates 221 fixedly connected to the upper end of the welding platform 11. A short-range electric telescopic rod 222 is fixedly connected to the support plate 221. The short-range electric telescopic rod 222 can adjust the telescopic length according to actual needs. The telescopic end of the short-range electric telescopic rod 222 is fixedly connected to a suction cup 223.

[0026] The third fixing component 23 includes a top plate 231 fixedly connected to the side wall of the workbench 1. A long-range electric telescopic rod 232 is fixedly connected to the lower end of the top plate 231. The telescopic end of the long-range electric telescopic rod 232 is fixedly connected to two symmetrically arranged electric claws. The telescopic end of the long-range electric telescopic rod 232 is fixedly connected to two symmetrically arranged electric claws. The electric claws are used to clamp the top frame. The top plate 231 is lowered to the specified welding position through the long-range electric telescopic rod 232 to complete the positioning of the top frame.

[0027] Specifically, an adsorption groove is opened on the side wall of the suction cup 223. The adsorption groove is communicated with an air pump arranged inside the suction cup 223. When the air pump is started, negative pressure is formed in the adsorption groove, thereby enhancing the adsorption force of the suction cup 223 on the side plate and ensuring the stability of the side plate during the welding process.

[0028] The circumferential welding mechanism 3 is used to continuously weld the bottom frame and the side plates on the circumferential side, improving the welding efficiency and quality. The circumferential welding mechanism 3 includes a fixed disk 31 fixedly connected to the upper end of the welding platform 11, and the fixed disk 31 provides a stable installation foundation for the circumferential guide rail 32. The circumferential guide rail 32 is fixedly connected to the circumference of the fixed disk 31, and the circumferential guide rail 32 provides a track for the movement of the rotating rod 34 and the mounting plate 37. A circumferential chute 33 is opened on the inner bottom wall of the circumferential guide rail 32, and a rotating rod 34 is movably installed in the circumferential chute 33. The rotating rod 34 can freely rotate and move in the circumferential chute 33. A driving motor is provided below the circumferential guide rail 32. As a power source, the output end of the driving motor is fixedly connected to the rotating rod 34. After the driving motor is started, it drives the rotating rod 34 to rotate. A moving gear 35 is fixedly connected to the part of the rotating rod 34 extending into the circumferential guide rail 32. A circumferential tooth groove 36 is opened on one inner wall of the circumferential guide rail 32. The moving gear 35 meshes with the circumferential tooth groove 36, so that when the rotating rod 34 rotates, it can make a circumferential movement along the circumferential guide rail 32. The top end of the rotating rod 34 is rotatably connected to a mounting plate 37 for driving the welding gun 12. The mounting plate 37 moves with the movement of the rotating rod 34, and then drives the welding gun 12 to continuously weld the bottom frame and the side plates.

[0029] Specifically, an L-shaped limiting rod 5 is fixedly connected to the lower end of the mounting plate 37. A circumferential limiting groove 51 is opened on the circumferential outer wall of the circumferential guide rail 32. The L-shaped limiting rod 5 is slidably connected to the inner wall of the circumferential limiting groove 51. The mounting plate 37 is limited by the L-shaped limiting rod 5 and the circumferential limiting groove 51 to prevent the mounting plate 37 from shifting during the movement, ensuring the accurate movement track of the welding gun 12 and improving the welding accuracy.

[0030] The adjusting mechanism 4 is used to adjust the position of the welding gun 12 to realize the switching of the welding position of the welding gun 12 and meet the welding requirements of different parts. The adjusting mechanism 4 includes a hinge seat 41 arranged on the side wall of the mounting plate 37. The hinge seat 41 provides a hinge point for the adjusting rod 42, enabling it to swing around the hinge seat 41. An adjusting motor 43 for controlling the swinging angle of the adjusting rod 42 is fixedly connected to the hinge seat 41. After the adjusting motor 43 is started, the swinging angle of the adjusting rod 42 can be accurately controlled. The end of the adjusting rod 42 far from the hinge seat 41 is rotatably connected to an adjusting roller 44. The adjusting roller 44 can rotate under the drive of the adjusting rod 42. A telescopic block 45 is fixedly connected to the adjusting roller 44. The welding gun 12 is fixedly connected to the telescopic block 45. The swinging of the adjusting rod 42 and the rotation of the adjusting roller 44 can realize the adjustment of the position and angle of the welding gun 12.

[0031] The control mechanism 6 is used to synchronously adjust the welding current of the welding gun 12 and the welding speed of the welding gun 12 when the welding position is switched to ensure the welding quality.

[0032] The control mechanism 6 includes an adjustment cavity 61 and a control cavity 62 opened inside the adjustment rod 42. The adjustment cavity 61 provides a moving space for the counterweight 63. A counterweight 63 is hermetically and slidably connected inside the adjustment cavity 61. A stress spring 64 is provided between the counterweight 63 and the inner wall of the adjustment cavity 61, and the stress spring 64 plays a role in buffering and resetting. One side of the counterweight 63 close to the control cavity 62 is fixedly connected with a push rod 65. The push rod 65 extends into the control cavity 62 and is fixedly connected with a first sliding plate 66. A first resistance rod 67 is fixedly connected inside the control cavity 62. The first resistance rod 67 penetrates and is slidably connected to the first sliding plate 66. A first sliding rheostat is formed between the first sliding plate 66 and the first resistance rod 67. The welding gun 12 and the driving motor are electrically connected to the first sliding rheostat. When the inclination state of the adjustment rod 42 changes, the position of the counterweight 63 in the adjustment cavity 61 changes, driving the first sliding plate 66 to slide on the first resistance rod 67 through the push rod 65, thereby changing the resistance value in the circuit and realizing the adjustment of the welding current of the welding gun 12 and the rotation speed of the driving motor.

[0033] Specifically, one end of the counterweight 63 far from the stress spring 64 is fixedly connected with a traction rope 7. The traction rope 7 extends outside the adjustment rod 42 and is fixedly connected with the adjustment roller 44. A torsion spring 71 is provided between the adjustment roller 44 and the adjustment rod 42. When the inclination state of the adjustment rod 42 changes, the position change of the counterweight 63 in the adjustment cavity 61 will drive the adjustment roller 44 to rotate through the traction rope 7. The torsion spring 71 plays a certain buffering and resetting role, enabling the adjustment roller 44 to drive the welding gun 12 to perform an angular adjustment of a certain amplitude. The angle of the adjusted welding gun 12 and the angle of the welding gun 12 before adjustment are symmetrically arranged with respect to the horizontal line, ensuring the accuracy of the welding position.

[0034] An extension mechanism 8 is provided on the mounting plate 37, which is used to extend the welding gun 12 when the welding gun 12 moves to the corner positions of the two side plates, ensuring that the welding gun 12 can penetrate into the corner positions and improving the welding quality. The extension mechanism 8 includes a strip-shaped groove 81 opened at the upper end of the mounting plate 37, and the strip-shaped groove 81 provides a sliding track for the support rod 82. A support rod 82 is slidably connected in the strip-shaped groove 81, and the support rod 82 can slide freely in the strip-shaped groove 81. The upper end of the support rod 82 is rotatably connected with a guide wheel 83. Guide blocks 84 are fixedly connected to the respective corners of the circumferential guide rail 32 through connecting rods. The corners of the guide blocks 84 are convexly arranged outward, and the guide wheel 83 contacts and rolls with the guide block 84. When the mounting plate 37 moves to the corner of the circumferential guide rail 32, the protruding position on the guide block 84 pushes the guide wheel 83 to move along the strip-shaped groove 81. A second sliding piece 85 is fixedly connected to the support rod 82, and a second resistance rod 86 is fixedly connected to the upper end of the mounting plate 37. A second sliding rheostat is formed between the second sliding piece 85 and the second resistance rod 86. The telescopic block 45 includes a fixed part 87 fixedly connected to the adjusting roller 44. A sliding part 88 is slidably connected to the fixed part 87. The welding gun 12 is fixedly connected to the sliding part 88. A compression spring 89 is provided between the fixed part 87 and the sliding part 88. Electromagnets 810 are provided on the side walls of the fixed part 87 and the sliding part 88 that are close to each other. The two electromagnets 810 repel each other with the same poles. The second sliding rheostat is electrically connected to the two electromagnets 810. The movement of the guide wheel 83 drives the second sliding piece 85 to slide on the second resistance rod 86, increasing the current in the circuit where the two electromagnets 810 are located, increasing the magnetic repulsion force between the electromagnets 810, overcoming the elastic force of the compression spring 89, enabling the sliding part 88 to displace relative to the fixed part 87, and extending the welding gun 12 into the included angle position between the two side plates, improving the welding effect on the included angle position.

[0035] The functional principle of the present invention can be elaborated through the following operation methods: Before performing the container welding operation, first start the clamping mechanism 2, turn on the fixed motor, the fixed motor drives the fixed screw to rotate, so that the clamping plate 212 slides along the inner wall of the fixed groove 211 and moves closer to clamp the bottom frame. At the same time, start the electric claw, use the long-range electric telescopic rod 232 to lower the top plate 231, so that the electric claw clamps the top frame. Start the air pump, and the suction disc 223 generates negative pressure through the suction groove to adsorb the side plate, and then the short-range electric telescopic rod 222 pushes the side plate to the designated welding position where it fits with the bottom frame and the top frame, completing the clamping and positioning of each component; Then, start the drive motor of the circumferential welding mechanism 3, the drive motor drives the rotating rod 34 to rotate, the moving gear 35 on the rotating rod 34 meshes with the circumferential tooth groove 36, so that the rotating rod 34 makes a circumferential movement along the circumferential sliding groove 33, and further drives the mounting plate 37 and the welding gun 12 to make a circular movement around the connection between the bottom frame and the side plate, starting the welding operation; During the welding process, when the welding gun 12 switches from welding the bottom frame and the side plate to welding the top frame and the side plate, the adjustment motor 43 of the adjustment mechanism 4 is started. The adjustment motor 43 drives the adjustment rod 42 to swing, changing the position of the welding gun 12. At the same time, the change in the inclination state of the adjustment rod 42 causes the counterweight 63 in the control mechanism 6 to move within the adjustment cavity 61. When the adjustment rod 42 inclines downward to weld the bottom frame and the side plate, the counterweight 63 moves away from the mounting plate 37 under the action of gravity, and pushes the first sliding piece 66 to slide on the first resistance rod 67 through the push rod 65, reducing the circuit resistance, increasing the welding current of the welding gun 12 and the rotational speed of the drive motor, and improving the welding speed. When the adjustment rod 42 inclines upward to weld the top frame and the side plate, the counterweight 63 approaches the mounting plate 37, and the position of the first sliding piece 66 on the first resistance rod 67 changes, increasing the circuit resistance, reducing the welding current of the welding gun 12 and the rotational speed of the drive motor, ensuring the stability of the molten pool. During the swinging process of the adjustment rod 42, the counterweight 63 drives the adjustment roller 44 to rotate through the traction rope 7, enabling the welding gun 12 to perform angle adjustment and ensuring the accuracy of the welding position. When the welding gun 12 moves to the corner position of the two side plates, the extension mechanism 8 starts to work. The mounting plate 37 moves to the corner of the circumferential guide rail 32. The guide block 84 pushes against the guide wheel 83, causing the support rod 82 to slide within the strip-shaped groove 81. The second sliding piece 85 moves on the second resistance rod 86, increasing the current in the circuit where the electromagnet 810 is located. The magnetic repulsion force between the electromagnets 810 increases, pushing the sliding part 88 to move relative to the fixed part 87, and the welding gun 12 penetrates into the included angle position, improving the welding effect.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
