Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to automated steel structure welding equipment. Background Art

[0002] The automatic welding machine for structural steel is an efficient equipment that uses automation technology to weld structural steel parts. It is mainly composed of a three-axis mobile platform, a machine body and a welding head. When in use, the operator inputs the corresponding welding parameters through the machine body, such as current, voltage, welding speed, etc. The three-axis mobile platform drives the welding head to move along the part to be welded to automatically weld the weldment. When the structural steel is thicker, a single layer of welding often cannot meet the needs. Multi-layer and multi-pass welding is often performed to ensure the quality of the weld and the stability of the structure. After each layer is welded, the slag is knocked off and the weld is cleaned, and then the next layer is welded until the multi-layer welding is completed. And when the structural steel is thicker, it is easy to produce greater stress and deformation during the welding process, so it is usually necessary to preheat before welding.

[0003] During the use of existing steel structure welding automation equipment, there is generally no mechanism for automatically cleaning the welding slag during multi-layer and multi-pass welding. After welding one layer, the welding slag will cover the weld surface in the form of a solid shell. The welding slag on the weld needs to be manually broken and cleaned so that the next layer of welding can be carried out on the basis of the current weld. This method is not convenient enough, and before welding thicker structural steel, it is generally necessary to manually preheat the welding part, which is not convenient enough. Summary of the invention

[0033] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0034] Example 1

[0035] like Figures 1 to 8 As shown in the figure, it is the first embodiment of the present invention, which provides a steel structure welding automation equipment, including a three-axis mobile platform 10, on which an organic body 11 and a welding head 12 are installed; a knocking mechanism 20, which is arranged on the outside of the welding head 12 and is used to break the welding slag, and the knocking mechanism 20 includes a first shell 21 fixedly connected to the outer wall of the welding head 12, a rotating arm 22 is rotatably installed in the first shell 21, and a push block 23 is slidably installed on the rotating arm 22, and a hammer rod 24 is slidably connected to the first shell 21 along the vertical direction, and a hammer head 25 is installed at the bottom of the hammer rod 24. A lifting arm 26 is fixedly installed on the rod 24, and the lifting arm 26 is in contact with the push block 23. A spring 27 is connected between the hammer rod 24 and the first shell 21; a blower mechanism 30 is arranged on both sides of the welding head 12, and is used to preheat the welding part and blow away the broken welding slag. The blower mechanism 30 includes two second shells 31 fixedly connected to the outer walls of both sides of the welding head 12, and a fan 32 is rotatably installed inside the second shell 31. The fan 32 is transmission-connected to the rotating arm 22, and a heating component 33 is provided below the fan 32, and the heating component 33 is fixedly connected to the inner wall of the second shell 31.

[0036] It should be noted that the three-axis mobile platform 10 is a prior art, also known as a three-coordinate mobile platform. It is a platform that can achieve precise movement in the three directions of X, Y and Z. 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 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 repeated here. The body 11 is a prior art, which is used to control the welding head 12 to perform welding according to the welding parameters input by the operator. It will not be repeated here. The fan 32 is a prior art, including a frame and blades rotatably connected to the frame. A rotating shaft is often provided on the blade 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 blade to rotate, which is used to blow air to one side. It will not be repeated here. The heating component 33 is a prior art, which converts electrical energy into thermal energy through an internally arranged high-resistivity electric heating wire to heat the air blown out by the fan 32. It will not be repeated here.

[0037] When the present invention is in use, in the process of multi-layer and multi-pass welding of thicker structural steel, when one layer of welding is required, the three-axis mobile platform 10 drives the welding head 12 to move along the part to be welded and weld after it is started. At this time, the push block 23 slides along the rotating arm 22 and then retracts into the inside of the rotating arm 22, so that after the rotating arm 22 rotates, the lifting arm 26 is no longer driven to move by the push block 23. After the rotating arm 22 rotates, the fan 32 is driven to rotate, so that the fan 32 blows gas from top to bottom onto the part to be welded. After the heating component 33 works, the blown gas is heated to preheat the part to be welded outside the welding head 12. Compared with the traditional method of manually preheating the part to be welded, the convenience is improved. After one layer of welding is completed, the push block 23 slides along the rotating arm 22 and then extends to the outside of the rotating arm 22, so that after the rotating arm 22 rotates, the lifting arm 26 is driven to move by the push block 23. In this process, the push block 23 first moves to the bottom of the lifting arm 26 and connects with the bottom of the lifting arm 26. As the rotating arm 22 rotates, the push block 23 pushes up the lifting arm 26, 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. When the push block 23 moves to the end of the lifting arm 26 and separates from the lifting arm 26, the spring 27 drives the hammer rod 24 and the hammer head 25 to fall and smash the welding slag under the elastic action. After the rotating arm 22 rotates, the push block 23 repeatedly pushes up the lifting arm 26, and the spring 27 drives the lifting arm 26 through the hammer rod 24 under the elastic action. 6 moves downward, so that the lifting arm 26, the hammer rod 24 and the hammer head 25 move up and down reciprocatingly, so that the hammer head 25 repeatedly strikes the welding slag. After the three-axis moving platform 10 works, the hammer head 25 is driven by the welding head 12 to move along the welding seam to break the welding slag covered on the welding seam. In this process, the rotating arm 22 also drives the fan 32 to rotate to blow away the broken welding slag on the welding seam outside the hammer head 25. Compared with the traditional method of manually breaking the welding slag on the welding seam and cleaning it, the convenience is improved.

[0038] Among them, the blower mechanism 30 is arranged on both sides of the welding head 12 and the hammer head 25, and blows air on both sides of the welding head 12 and the hammer head 25. When performing one layer of welding, the heating component 33 on the side close to the moving direction of the welding head 12 works to preheat the welding part, and the heating component 33 on the side away from the moving direction of the welding head 12 does not work to cool the weld after welding, which is beneficial to breaking and cleaning the welding slag after welding one layer, and by adjusting the working state of the heating components 33 on both sides of the welding head 12 to adapt to the different moving directions of the welding head 12, it is convenient to eliminate the asymmetry of welding stress by making the welding direction of each layer of weld opposite in the process of multi-layer and multi-pass welding.

[0039] Example 2

[0040] Reference Figures 1 to 8, which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] like Figure 4 As shown, both sides of the rotating arm 22 are rotatably connected to the inner wall of the first shell 21, a first gear 221 is fixedly connected to the rotating arm 22, a first motor 28 is fixedly installed on the first shell 21, and a second gear 281 is fixedly connected to the output end of the first motor 28, and the second gear 281 is meshed with the first gear 221.

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

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

[0044] According to the above structure, after the first motor 28 works, it drives the rotating arm 22 to rotate. After the rotating arm 22 rotates, it drives the first transmission wheel 35 to rotate through the first bevel gear 222. The first transmission wheel 35 drives the second transmission wheel 36 to rotate through the transmission belt 37. The second transmission wheel 36 drives the fan 32 to rotate for blowing air, thereby realizing that the rotating arm 22 drives the fan 32 to blow air. 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 a driving source, reducing the number of driving sources.

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

[0046] According to the above structure, after the electric telescopic rod 29 works, the output end extends or shortens, driving 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 then drive the lifting arm 26 to move through the push block 23. At this time, after the first motor 28 works, it drives the hammer head 25 and the fan 32 to move, which is convenient for adapting to the situation of smashing and removing 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 without driving the lifting arm 26 to move through the push block 23. At this time, after the first motor 28 works, it only drives the fan 32 to move but does not drive the hammer head 25 to move, which is convenient for adapting to the situation of preheating one layer of welding.

[0047] like Figure 6 As shown, a slide plate 41 is slidably connected to the rotating arm 22, the electric telescopic rod 29 is fixedly connected to the slide plate 41, a first limiting hole 411 is opened inside the slide plate 41, a plurality of second limiting holes 223 are opened radially on the rotating arm 22, a first limiting pin 42 is slidably connected inside the first limiting hole 411 and the second limiting hole 223, a sliding hole 224 is opened radially inside the rotating arm 22, and the sliding hole 224 is slidably matched with the push block 23.

[0048] It should be noted that the force with which the hammer head 25 strikes the welding slag downward 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 in the spring 27. When the external force is removed, these energies will be converted into kinetic energy, causing the hammer head 25 to move faster and affect the speed of the hammer head 25 when striking. In terms of weight, the force with which the hammer head 25 strikes the welding slag can be changed by changing the weight of the hammer head 25.

[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 pulled out from the first limiting hole 411 and the second limiting hole 223, and the slide plate 41 is moved along the rotating arm 22. The slide plate 41 drives the push block 23 to slide along the sliding hole 224 through the first limiting pin 42, so that the first limiting hole 411 is aligned with the second limiting hole 223 at a suitable position, and the first limiting pin 42 is inserted into the first limiting hole 411 and the second limiting hole 223 to limit the slide 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 push block 23 and the rotating arm 22. The distance between the ends of the lifting arm 26 allows the push block 23 to separate from the lifting arm 26 earlier or later during the process of the push block 23 rotating with the rotating arm 22, thereby adjusting the maximum distance the lifting arm 26 moves upward, adjusting the degree of deformation of the spring 27 when the lifting arm 26 drives the hammer rod 24 to compress the spring 27, thereby adjusting the elastic potential energy stored in the deformation of the spring 27, adjusting the speed of the hammer head 25 when knocking the slag, and then adjusting the force of the hammer head 25 knocking the welding slag downward, so as to adapt to welding slag of different hardness, reduce the situation where excessive force damages the welding area, reduce the situation where too weak force makes it difficult to knock the welding slag into pieces, and improve applicability.

[0050] like Figure 6 As shown, the lifting arm 26 is connected to the hammer rod 24 in a horizontal sliding manner, a plurality of third limiting holes 261 are provided inside the lifting arm 26 along the sliding direction, a fourth limiting hole 241 is provided on the hammer rod 24, and a second limiting pin 43 is slidably connected between 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 end of the lifting arm 26 and the push block 23, the second limit pin 43 is pulled out from the inside of the fourth limit hole 241 and the third limit hole 261, and the lifting arm 26 is moved along the hammer rod 24 so that the fourth limit hole 241 is aligned with the third limit hole 261 at the appropriate position, and the second limit pin 43 is inserted into the inside of the fourth limit hole 241 and the third limit hole 261 to limit the lifting arm 26 and the hammer rod 24, thereby adjusting the distance between the end of the lifting arm 26 and the push block 23, so that the push block 23 is separated from the lifting arm 26 earlier or later during the rotation of the rotating arm 22, and then the force of the hammer head 25 to knock the welding slag downward is adjusted to facilitate adaptation to welding slag of different hardness.

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

[0053] It should be noted that the device is equipped with a plurality of hammer heads 25 of different weights to replace the hammer head 25 .

[0054] According to the above structure, the hammer head 25 and the hammer rod 24 are detachably connected through the threaded hole 251 and the threaded column 242. By disassembling and replacing hammer heads 25 of different weights to change the weight of the hammer head 25, the force with which the hammer head 25 strikes the welding slag downward is adjusted, so as to adapt to welding slag of different hardness.

[0055] like Figure 5 As shown, a plurality of limit strips 243 are fixedly connected to the hammer rod 24 along the circumferential direction, and the limit strips 243 are slidably matched with the first shell 21 along the vertical direction.

[0056] According to the above structure, the limit strip 243 cooperates with the first shell 21 to prevent the hammer rod 24 from rotating in the first shell 21 and affecting the movement of the lifting arm 26 driven by the push block 23, so that the process of the hammer rod 24 moving up and down along the first shell 21 is more stable, which is convenient for the hammer head 25 to crush the welding slag.

[0057] like Figure 8 As shown, a wind guide plate 38 is rotatably connected to the bottom of the second shell 31 , a second motor 39 is fixedly connected to the second shell 31 , and an output end of the second motor 39 is fixedly connected to the wind guide plate 38 .

[0058] It should be noted that an air inlet is provided at the top of the second shell 31 , and an air outlet is provided at the bottom of the second shell 31 .

[0059] According to the above structure, after the second motor 39 works, the output end drives the air guide plate 38 to rotate at the bottom of the second shell 31, and the angular position of the air guide plate 38 is adjusted. After the fan 32 rotates, the gas moved is discharged outward along the air guide plate 38, so that the blowing angle of the air blowing mechanism 30 can be adjusted by adjusting the angular position of the air guide plate 38, which is convenient for blowing at positions at different distances from the welding head 12 and the first transmission wheel 35, thereby improving the applicability of blowing.

[0060] like Figure 8 As shown, a filter screen 44 is disposed on the top of the second shell 31 , and the filter screen 44 is fixedly connected to the second shell 31 .

[0061] It should be noted that a plurality of filter holes are provided inside the filter screen 44, and the aperture size of the filter holes is smaller than the diameter size of impurities such as dust.

[0062] According to the above structure, the filter 44 prevents external impurities from entering the second housing 31, thereby reducing the possibility that the fan 32 blows the impurities into the welded area or weld after the fan 32 rotates.

[0063] The working principle of the present invention is as follows: when performing multi-layer and multi-pass welding on thicker structural steel, the three-axis mobile platform 10 drives the welding head 12 to move along the part to be welded and perform welding after it starts working. At this time, the rotating arm 22 rotates to drive the fan 32 to rotate and blow gas. The heating component 33 on the side close to the forward direction of the welding head 12 heats the gas blown by the fan 32 after it starts working, so that the blowing mechanism 30 preheats the part to be welded on the side close to the forward direction of the welding head 12. Compared with the traditional method of manually preheating the part to be welded, the convenience is improved. After welding one layer, the rotating arm 22 rotates and drives the hammer head 25 to move up and down to break the welding slag. After the rotating arm 22 rotates, it also drives the fan 32 to blow out the broken welding slag. Compared with the traditional method of manually breaking the welding slag on the weld and cleaning it, the convenience is improved.

[0064] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
