Description

TECHNICAL FIELD

[0002] The structural steel automatic welding machine is a high-efficiency equipment for welding structural steel parts by using automatic technology, which mainly comprises a three-axis moving platform, a machine body and a welding head. When in use, an operator inputs corresponding welding parameters such as current, voltage and welding speed through the machine body, and the three-axis moving platform drives the welding head to move along the part to be welded to automatically weld the welded part. When the structural steel is thick, single-layer welding cannot meet the requirements, and multi-layer and multi-pass welding is often used to ensure the quality of the weld and the stability of the structure. After each layer of welding is completed, the slag is knocked and the weld is cleaned, and then the next pass is welded until the multi-layer welding is completed. When the structural steel is thick, large stress and deformation are easily generated during the welding process, and therefore, preheating is usually required before welding.

Detailed Implementation

[0033] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0034] Example 1

[0035] like Figures 1 to 8 As shown, this is the first embodiment of the present invention. This embodiment provides an automated steel structure welding device, including a three-axis moving platform 10, on which an organism 11 and a welding head 12 are mounted; a striking mechanism 20 is disposed on the outside of the welding head 12 for breaking welding slag. The striking mechanism 20 includes a first housing 21 fixedly connected to the outer wall of the welding head 12, a rotating arm 22 rotatably mounted in the first housing 21, a push block 23 slidably mounted on the rotating arm 22, a hammer rod 24 slidably connected in the vertical direction in the first housing 21, and a hammer head 25 mounted at the bottom of the hammer rod 24. A lifting arm 26 is fixedly installed on the rod 24, and the lifting arm 26 abuts against the push block 23. A spring 27 is connected between the hammer rod 24 and the first housing 21. A blower mechanism 30 is set on both sides of the welding head 12 and is used to preheat the part to be welded and blow away the broken welding slag. The blower mechanism 30 includes two second housings 31 that are fixedly connected to the outer walls of both sides of the welding head 12. A fan 32 is rotatably installed inside the second housing 31. The fan 32 is connected to the rotating arm 22. A heating component 33 is provided below the fan 32 and is fixedly connected to the inner wall of the second housing 31.

[0036] It should be noted that the three-axis moving platform 10 is existing technology, also known as a three-coordinate moving platform. It is a platform that achieves precise movement in the X, Y, and Z directions. It mainly includes an X-axis moving part, a Y-axis moving part, and a Z-axis moving part. Each axis is connected to a servo motor to achieve automatic adjustment, so as to drive the welding head 12 to move along the part to be welded and facilitate the welding of the welding head 12. It will not be described in detail here. The body 11 is existing technology and is used to control the welding head 12 to perform welding according to the welding parameters input by the operator. It will not be described in detail here. The fan 32 is existing technology and includes a frame and blades rotatably connected in the frame. The blades are usually provided with a rotating shaft as the input end of the fan 32. By connecting the output end of the motor to the input end of the fan 32, the motor drives the blades to rotate for blowing air to one side. It will not be described in detail here. The heating component 33 is existing technology. It converts electrical energy into heat energy through an internally set high resistivity electric heating wire to heat the air blown out by the fan 32. It will not be described in detail here.

[0037] In use, during the multi-layer multi-pass welding of thick structural steel, when a layer of welding is needed, the three-axis moving platform 10 drives the welding head 12 to move along the part to be welded and performs welding after working, at this time the push block 23 is retracted to the inside of the rotating arm 22 after sliding along the rotating arm 22, so that the rotating arm 22 is no longer driven by the push block 23 to move the lifting arm 26 after rotating, the rotating arm 22 drives the fan 32 to rotate after rotating, so that the fan 32 blows the gas from top to bottom on the part to be welded, and the heating assembly 33 works to heat the blown gas to preheat the part to be welded outside the welding head 12. Compared with the traditional way of manually preheating the part to be welded, the convenience is improved, and when a layer of welding is completed, the push block 23 is extended to the outside of the rotating arm 22 after sliding along the rotating arm 22, so that the rotating arm 22 drives the lifting arm 26 to move through the push block 23 after rotating. In this process, the push block 23 first moves to the lower side of the lifting arm 26 and contacts the bottom of the lifting arm 26, and as the rotating arm 22 rotates, the push block 23 lifts the lifting arm 26 upward, so that the lifting arm 26 drives the hammer rod 24 and the hammer head 25 to move upward. At this time, the spring 27 is compressed, and when the push block 23 moves to the end of the lifting arm 26 and is separated from the lifting arm 26, the spring 27 drives the hammer rod 24 and the hammer head 25 to fall and crush the welding slag under the action of elasticity. The rotating arm 22 rotates to repeatedly lift the lifting arm 26 by the push block 23, and the spring 27 drives the lifting arm 26 to move downward through the hammer rod 24 under the action of elasticity, so that the lifting arm 26, the hammer rod 24 and the hammer head 25 move up and down repeatedly, so that the hammer head 25 repeatedly strikes the welding slag. The three-axis moving platform 10 drives the hammer head 25 to move along the weld through the welding head 12 to crush the welding slag covering the weld. In this process, the rotating arm 22 also drives the fan 32 to rotate to blow away the welding slag on the outside of the hammer head 25 that has been crushed. Compared with the traditional way of manually crushing and cleaning the welding slag on the weld, the convenience is improved.

[0038] Among them, the air blowing mechanism 30 is arranged on both sides of the welding head 12 and the hammer head 25, and air is blown to both sides of the welding head 12 and the hammer head 25. When a layer of welding is performed, the heating assembly 33 on the side close to the moving direction of the welding head 12 works to preheat the part to be welded, and the heating assembly 33 on the side away from the moving direction of the welding head 12 does not work to cool the welded weld. It is beneficial to crush and clean the welding slag after welding a layer, and by adjusting the working state of the heating assembly 33 on both sides of the welding head 12 to adapt to different moving directions of the welding head 12, it is convenient to make the welding direction of each layer of weld opposite to eliminate the asymmetry of welding stress during multi-layer multi-pass welding.

[0042] According to the above structure, the output end of the first motor 28 drives the second gear 281 to rotate after the first motor 28 works, and the second gear 281 drives the rotating arm 22 to rotate through the first gear 221, so as to conveniently drive the hammer head 25 to knock the slag and drive the fan 32 to rotate and blow air by driving the rotating arm 22.

[0043] As Figure 4 and Figure 8 shown, the two sides of the rotating arm 22 are fixedly connected with a first bevel gear 222, the inner wall of the second shell 31 is rotatably connected with a second bevel gear 34, the second bevel gear 34 is engaged with the first bevel gear 222, the second bevel gear 34 is fixedly connected with a first transmission wheel 35, the input end of the fan 32 is fixedly connected with a second transmission wheel 36, and the second transmission wheel 36 and the first transmission wheel 35 are connected with a transmission belt 37.

[0044] According to the above structure, the first motor 28 drives the rotating arm 22 to rotate after the first motor 28 works, and the rotating arm 22 drives the first transmission wheel 35 to rotate through the first bevel gear 222 after the rotating arm 22 rotates, the first transmission wheel 35 drives the second transmission wheel 36 to rotate through the transmission belt 37, and the second transmission wheel 36 drives the fan 32 to rotate to blow air, so as to realize that the rotating arm 22 drives the fan 32 to blow air, and the first motor 28 not only drives the hammer head 25 to move up and down, but also drives the fan 32 to rotate, so that the hammer head 25 and the fan 32 share one driving source, and the number of driving sources is reduced.

[0045] As Figure 6 shown, the rotating arm 22 is slidably installed with an electric telescopic rod 29, and the output end of the electric telescopic rod 29 is fixedly connected with the push block 23.

[0046] According to the above structure, the output end of the electric telescopic rod 29 is extended or shortened after the electric telescopic rod 29 works, and drives the push block 23 to slide along the rotating arm 22, when the electric telescopic rod 29 drives the push block 23 to slide and extend to the outside of the rotating arm 22, it is convenient for the rotating arm 22 to rotate and drive the lifting arm 26 to move through the push block 23, at this time, the first motor 28 drives the hammer head 25 and the fan 32 to act after working, it is convenient to adapt to the situation of knocking and removing the welding slag, when the electric telescopic rod 29 drives the push block 23 to slide and shrink to the inside of the rotating arm 22, it is convenient for the rotating arm 22 to rotate and not to drive the lifting arm 26 to move through the push block 23, at this time, the first motor 28 only drives the fan 32 to act without driving the hammer head 25 to act after working, it is convenient to adapt to the situation of one layer of welding preheating.

[0047] As shown in Figure 6 The rotating arm 22 is slidably connected with a sliding plate 41, the electric telescopic rod 29 is fixedly connected with the sliding plate 41, the inside of the sliding plate 41 is provided with a first limiting hole 411, the rotating arm 22 is provided with a plurality of second limiting holes 223 along the radial direction, the first limiting hole 411 and the second limiting hole 223 are slidably connected with a first limiting pin 42, the inside of the rotating arm 22 is provided with a sliding hole 224 along the radial direction, and the sliding hole 224 is slidably connected with the push block 23.

[0048] It should be noted that the force of the hammer head 25 to knock the welding slag is mainly affected by the speed and weight of the hammer head 25, in terms of speed, the greater the deformation of the spring 27 after compression, the greater the elastic potential energy stored by the spring 27, when the external force is removed, these energies will be converted into kinetic energy, so that the hammer head 25 moves at a higher speed, and in terms of weight, by changing the weight of the hammer head 25, the force of the hammer head 25 to knock the welding slag can be changed.

[0049] According to the above structure, when it is necessary to adjust the distance between the push block 23 and the end of the lifting arm 26, the first limiting pin 42 is extracted from the inside of the first limiting hole 411 and the second limiting hole 223, the sliding plate 41 is moved along the rotating arm 22, the sliding plate 41 drives the push block 23 to slide along the sliding hole 224 through the first limiting pin 42, the first limiting hole 411 is aligned with the second limiting hole 223 at the appropriate position, the first limiting pin 42 is inserted into the inside of the first limiting hole 411 and the second limiting hole 223 and limits the sliding plate 41 and the rotating arm 22, so that the relative position of the push block 23 and the rotating arm 22 remains fixed, thereby adjusting the distance between the push block 23 and the end of the lifting arm 26, so that the push block 23 is separated from the lifting arm 26 earlier or later in the process of rotating the rotating arm 22, thereby adjusting the maximum distance of the lifting arm 26 moving upward, adjusting the deformation degree of the spring 27 when the lifting arm 26 drives the hammer rod 24 to compress the spring 27, thereby adjusting the size of the elastic potential energy stored by the deformation of the spring 27, adjusting the speed of the hammer head 25 when knocking the slag, and further adjusting the force of the hammer head 25 knocking down the welding slag, so as to adapt to welding slag of different softness and hardness, reduce the damage to the welding area caused by excessive force, reduce the difficulty of knocking the slag caused by insufficient force, and improve the applicability.

[0050] As shown in Figure 6 , the lifting arm 26 and the hammer rod 24 are connected in sliding connection in the horizontal direction, the inside of the lifting arm 26 is provided with a plurality of third limiting holes 261 in the sliding direction, and the fourth limiting hole 241 is provided on the hammer rod 24. The second limiting pin 43 is in sliding connection with the inside of the fourth limiting hole 241 and the third limiting hole 261.

[0051] According to the above structure, when it is necessary to adjust the distance between the push block 23 and the end of the lifting arm 26, the first limiting pin 42 is extracted from the inside of the first limiting hole 411 and the second limiting hole 223, the sliding plate 41 is moved along the rotating arm 22, the sliding plate 41 drives the push block 23 to slide along the sliding hole 224 through the first limiting pin 42, the first limiting hole 411 is aligned with the second limiting hole 223 at the appropriate position, the first limiting pin 42 is inserted into the inside of the first limiting hole 411 and the second limiting hole 223 and limits the sliding plate 41 and the rotating arm 22, so that the relative position of the push block 23 and the rotating arm 22 remains fixed, thereby adjusting the distance between the push block 23 and the end of the lifting arm 26, so that the push block 23 is separated from the lifting arm 26 earlier or later in the process of rotating the rotating arm 22, thereby adjusting the maximum distance of the lifting arm 26 moving upward, adjusting the deformation degree of the spring 27 when the lifting arm 26 drives the hammer rod 24 to compress the spring 27, thereby adjusting the size of the elastic potential energy stored by the deformation of the spring 27, adjusting the speed of the hammer head 25 when knocking the slag, and further adjusting the force of the hammer head 25 knocking down the welding slag, so as to adapt to welding slag of different softness and hardness, reduce the damage to the welding area caused by excessive force, reduce the difficulty of knocking the slag caused by insufficient force, and improve the applicability.

[0052] As shown in Figure 7 , the end of the hammer rod 24 close to the hammer head 25 is fixedly connected with a threaded column 242, and the end of the hammer head 25 close to the hammer rod 24 is provided with a threaded hole 251, which is in threaded connection with the threaded column 242.

[0055] As shown in Figure 5 The hammer rod 24 is fixedly connected with several limiting strips 243 along the circumference, and the limiting strips 243 are slidingly matched with the first shell 21 in the vertical direction.

[0056] According to the above structure, the limiting strips 243 are matched with the first shell 21 to avoid the rotation of the hammer rod 24 in the first shell 21, which affects the movement of the push block 23 driving the lifting arm 26, so that the process of the hammer rod 24 moving up and down along the first shell 21 is more stable, and the hammer head 25 is convenient for crushing the welding slag.
