Description

Technical Field

[0001] This utility model relates to the field of steel structure welding and processing technology, specifically to a steel structure welding workbench. Background Technology

[0002] Steel structures typically include structures made of steel or alloy steel, such as I-beams, square steel, steel plates, and steel pipes. To improve welding precision, welding workbenches are usually used for product manufacturing and repair.

[0003] According to the Chinese patent publication number CN214816147U, "A Steel Structure Welding Workbench", the main description is that the workers hoist two sets of steel components onto the lifting platforms of two sets of adjustment platforms. At this time, the workers can slide the adjustment platforms back and forth, and then adjust the height of the lifting platforms through the lifting components. Since the upper surface of the lifting platform is smooth, the workers can slightly adjust the angle and position of the steel components. The electromagnetic chuck is used to initially lock the two sets of steel components, so that the two sets of steel components are spliced ​​with high precision, thereby completing the welding process of the steel components efficiently and with high precision.

[0004] When welding steel structures, welding workbenches require combining two identical or different steel structures at a certain spacing and position, and then using a welding torch to move the components to facilitate welding. However, during the welding process, air bubbles are generated when the welding area comes into contact with the air in the welding environment, resulting in poor welding results.

[0005] Therefore, a steel structure welding workbench is proposed to solve the problem that air bubbles are generated when the welding part comes into contact with the air in the welding environment, resulting in poor welding effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is that air bubbles will be generated when the welding part comes into contact with the air in the welding environment, resulting in poor welding effect. Therefore, a steel structure welding workbench is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is as follows: a steel structure welding workbench, including a fixed plate, a first limiting groove is opened on the upper side of the fixed plate, a first motor is fixedly connected to the fixed plate on one side of the first limiting groove, a first bidirectional lead screw is fixedly connected to the output end of the first motor, clamping bars are threadedly connected to the two mutually distant sides of the first bidirectional lead screw, a second limiting groove is opened on the clamping bar, a second motor is fixedly connected to one side of the clamping bar, a second bidirectional lead screw is fixedly connected to the output end of the second motor, clamping plates are threadedly connected to the two mutually distant sides of the second bidirectional lead screw, a recess is opened on the opposite side of the two clamping plates, a bracket is fixedly connected to the upper end of the fixed plate, and a connecting plate is fixedly connected to the upper end of the bracket, a third [unclear - possibly a component or part] is fixedly connected to one side of the upper end of the connecting plate. The motor has a third screw fixedly connected to its output end. A movable platform is threaded onto the third screw. A third limiting groove is formed inside the movable platform. A fourth motor is fixedly connected to one side of the movable platform located at the third limiting groove. A fourth screw is fixedly connected to the output end of the fourth motor. A slider is threaded onto the fourth screw. A welding torch is fixedly connected to the bottom end of the slider. A carbon dioxide cylinder is fixedly connected to one side of the fixed plate. An air pump is fixedly connected to the upper end of the carbon dioxide cylinder. A metal hose is fixedly connected to the output end of the air pump. The metal hose passes through the movable platform, and one end of the metal hose is fixedly connected to the slider. An annular groove is formed inside the slider. The annular groove communicates with the inside of the metal hose. Air outlet pipes are evenly formed on the bottom side of the annular groove. The air outlet pipes are aligned with the direction of the welding torch flame.

[0008] As a preferred technical solution of this utility model, a baffle is fixedly connected to the bottom side of the slider. The baffle is located outside the gas outlet pipe. By setting the frustum-shaped baffle, the contact between carbon dioxide gas and the welding torch ignition point can be increased.

[0009] As a preferred technical solution of this utility model, a positioning rod is provided on the upper side of the slider. The positioning rod is fixedly connected in the third limiting groove. Several auxiliary blocks are sleeved on the positioning rod. The auxiliary blocks are fixedly connected to the metal hose. By setting the positioning rod and auxiliary blocks, the excess length of the pipe can be reduced.

[0010] As a preferred technical solution of this utility model, a spring is sleeved on the positioning rod, and both ends of the spring are fixedly connected to the auxiliary block. By setting the spring, the tension of the metal hose can be increased and the scattered distribution of the metal hose can be reduced.

[0011] As a preferred technical solution of this utility model, electric push rods are fixedly connected to both sides of the bottom end of the moving platform. A pressure plate is fixedly connected to the bottom end of the electric push rod, and the pressure plate corresponds to the fixed plate. The pressure plate is pressed down by the electric push rod, which can promote the stability of the steel structure during welding.

[0012] As a preferred technical solution of this utility model, the upper end of the fixing plate is provided with a groove, and a heating plate is fixedly connected in the groove. The heating plate is connected to an external power source through a wire. By setting the heating plate, the steel structure can be heated, which promotes the preheating of the structure to be welded and improves the welding effect.

[0013] This invention has the following advantages: by setting an annular groove on the outside of the welding torch and using multiple air outlet pipes to spray carbon dioxide, a ring-shaped air jet structure is formed under the action of the baffle, which reduces the contact between the welding torch flame and the ambient air, thereby improving the welding speed and welding effect. At the same time, the heating plate preheats the steel structure to be welded, which can reduce welding stress and cracking tendency. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-3The steel structure welding workbench shown includes a fixed plate 1. A first limiting groove is formed on the upper side of the fixed plate 1. A first motor is fixedly connected to one side of the fixed plate 1 at the first limiting groove. The first motor drives a first bidirectional lead screw 2 to rotate, which can cause the clamping bars 3 to move relative to each other. The output end of the first motor is fixedly connected to the first bidirectional lead screw 2. Clamping bars 3 are threadedly connected to both sides of the first bidirectional lead screw 2 that are far apart from each other. A second limiting groove is formed on the clamping bars 3. A second motor is fixedly connected to one side of the clamping bars 3. The second motor controls the rotation of the second bidirectional lead screw 4, which can cause the two clamping plates 5 to move closer to each other. Alternatively, a second bidirectional lead screw 4 is fixedly connected to the output end of the second motor. Two clamping plates 5 are threaded onto the two opposite sides of the second bidirectional lead screw 4. Recesses are provided on opposite sides of the two clamping plates 5. A bracket is fixedly connected to the upper end of the fixed plate 1, and a connecting plate 6 is fixedly connected to the upper end of the bracket. A third motor is fixedly connected to one side of the upper end of the connecting plate 6. The third motor drives the third screw 7 to rotate, enabling the moving platform 8 to change height. The third screw 7 is fixedly connected to the output end of the third motor, and the moving platform 8 is threaded onto the third screw 7. A third limiting groove is provided inside the moving platform 8. 9. A fourth motor is fixedly connected to one side of the third limiting groove 9 on the moving stage 8. The fourth motor drives the fourth screw 10 to rotate, which can cause the slider 11 and the welding gun 12 to move. The output end of the fourth motor is fixedly connected to the fourth screw 10. The slider 11 is threadedly connected to the fourth screw 10. The bottom end of the slider 11 is fixedly connected to the welding gun 12. A carbon dioxide cylinder 13 is fixedly connected to one side of the fixed plate 1. An air pump 14 is fixedly connected to the upper end of the carbon dioxide cylinder 13. The air pump 14 draws gas from the carbon dioxide cylinder 13, passes through a gas flow controller (not shown in the figure), and then enters the metal... The flexible hose 15 is sprayed through the annular groove 16 and the exhaust pipe 17, which can guide carbon dioxide to correspond to the position of the welding torch 12, reducing the contact between the flame and the oxygen of the external environment, thereby improving the welding quality. The output end of the air pump 14 is fixedly connected to the metal flexible hose 15. The metal flexible hose 15 passes through the moving platform 8 and one end of the metal flexible hose 15 is fixedly connected to the slider 11. The slider 11 has an annular groove 16, which communicates with the inside of the metal flexible hose 15. The exhaust pipes 17 are evenly distributed on the bottom side of the annular groove 16. The exhaust pipes 17 are arranged in a ring and are aligned with the flame direction of the welding torch 12.

[0020] The baffle 18 is fixedly connected to the bottom side of the slider 11. The baffle 18 is located outside the air outlet pipe 17. By setting the baffle 18, the air outlet of multiple air outlet pipes 17 is guided, which can increase the friction and facilitate the formation of airflow in a circular area, reducing the contact between the welding torch and the external environment.

[0021] The metal hose 15 is fixedly connected to the auxiliary block 19, the auxiliary block 19 is sleeved with the positioning rod 20, the positioning rod 20 is fixedly connected in the third limiting groove 9, and the positioning rod 20 is located on the upper side of the slider 11. By setting the auxiliary block 19, the scattered distribution of the metal hose 15 can be reduced by connecting the metal hose 15.

[0022] Among them, a spring 21 is fixedly connected between two adjacent auxiliary blocks 19. The spring 21 is sleeved on the positioning rod 20. By setting the spring 21, the constraint on the metal hose 15 can be increased, and it can be avoided from being scattered.

[0023] Among them, the fixed plate 1 corresponds to the pressure plate 23. The pressure plate 23 is fixedly connected to the bottom end of the electric push rod 22. The electric push rod 22 is fixedly connected to both sides of the bottom end of the moving table 8. By setting the pressure plate 23 in conjunction with the clamping strip 3 and the clamping plate 5, the limiting position of the structure to be welded can be improved.

[0024] The external power supply is connected to the heating plate 24 in series via wires. The heating plate 24 is fixedly connected to the groove, which is located on the upper end of the fixed plate 1. By setting the heating plate 24, preheating of the steel structure to be welded can be provided, thereby improving the welding effect.

[0025] Working principle: The steel structures to be welded are placed on both sides of the heating plate 24 so that the welding surfaces face each other and are clamped by the clamping plate 5 and clamping strip 3. Then, the first bidirectional screw 2 rotates, and the two steel structures to be welded move relative to each other. At this time, the third screw 7 rotates, the moving table 8 moves down, and the slider 11 and welding torch 12 move and weld under the action of the fourth screw 10. During the welding process, the air pump 14 draws gas from the carbon dioxide cylinder 13, passes through the metal hose 15 and the annular groove 16, and then sprays it evenly from the gas outlet pipe 17. Under the action of the baffle 18, an airflow is formed around the outside of the welding torch 12, which reduces the contact between the welding torch and the gas in the external environment during welding, reduces welding cracks, and improves welding efficiency and welding effect.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
