Description

Technical Field

[0001] The present invention relates to the technical field of metal steel part welding, and more specifically, to a metal steel part welding device. Background Art

[0002] Metal steel parts refer to various parts and components made of metal materials, especially steel. When processing metal parts, it is necessary to weld the metal parts. Therefore, a metal steel part welding device is required. It usually consists of parts such as an electric welding pliers, a wire feeding mechanism, and a power source. High temperature is generated through arc discharge to melt the metal and solidify it into a weld seam, thereby achieving the connection of metals. Its working principle is based on arc welding technology. When current passes through the electrode and the workpiece, an arc generates high temperature to melt the contact point, and then filler metal is filled to form a weld seam. The wire feeding mechanism in the device is responsible for providing the welding wire, which is melted by arc heating and filled into the weld seam to complete the welding process. It is widely used in sheet metal processing in industries such as automobiles, ships, and aviation.

[0003] In the existing welding device, during use, the metal steel part is fixed by a clamping device, and then the welding device is started to weld the contact position of the metal steel part. At the same time, starting the wire feeding device can continuously convey the welding wire into the welding device, thereby ensuring that the welding device can continuously weld the metal steel part and improving the welding efficiency of the welding device. However, when the welding wire in the wire spool is used up, it is necessary to manually replace the wire spool to ensure the welding efficiency of the welding device. However, when replacing the wire spool, novice workers with unskilled operations often take more time compared to skilled workers, which is extremely likely to affect the welding efficiency of the metal steel part and reduce the welding efficiency of the welding device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The present application sets a replacement component, places the welding wire reel into the fixed frame, and drives the two No. 1 connecting blocks to move downward under the weight of the welding wire reel itself, thereby driving the two sliding positioning blocks to be inserted into the two ends of the welding wire reel, restricting the welding wire reel inside the fixed frame, and allowing the welding wire reel to rotate inside the fixed frame, so as to facilitate the extraction of the welding wire on the welding wire reel. When the welding wire on the welding wire reel is used up, the weight of the welding wire reel decreases, and the No. 1 spring drives the L-shaped slider to move upward, driving the sliding positioning block to move into the No. 1 slide slot, thereby releasing the restriction on the welding wire reel, and driving the No. 1 connecting block to move upward, ejecting the welding wire reel from the fixed frame to the discharge slide. Then, the U-shaped electric slide rail is started to drive the fixed frame to move, thereby driving the new welding wire reel to move to the position of the wire feeding device, and then one end of the welding wire on the welding wire reel is manually extracted and inserted into the wire feeding device, so that the replacement of the welding wire reel can be completed quickly, thereby improving the welding efficiency of the welding device.

[0019] (2) By setting up the ejection component in this application, when the first connecting block pushes the wire spool upward, it simultaneously pushes the second straight rod upward, thereby pulling out the first straight rod from the groove and releasing the fixation of the ejection plate. Then, the second spring drives the ejection plate to move upward in the third sliding groove, thereby pushing the wire spool upward on the side away from the discharge slide inside the fixing frame, and then accurately pushing the wire spool into the discharge slide, improving the usage effect of the replacement component.

[0020] (3) By setting up the feeding component in this application, several new wire spools are placed in the feeding slide. The center of the rotating wheel is downward, pushing the baffle plate downward to block the downward movement of the wire spool. Then, the rotating wheel rotates inside the circular through-hole. When the center of the rotating wheel rotates upward, the wire spool moves downward in the feeding slide under its own weight and falls into the fixing frame, thereby automatically placing the wire spool into the fixing frame and completing the replacement of the wire spool, improving the welding efficiency of the welding device.

[0021] (4) By setting up the insertion component in this application, the fourth spring drives the positioning rod to insert into the positioning hole, fixedly connecting the trapezoidal slider to the fixing frame. Then, the wire on the wire spool in the fixing frame is drawn out, and one end of the wire is passed through two groups of limiting pinch rollers to clamp one end of the wire. When the fixing frame drives the wire spool to move towards the wire feeding device, it simultaneously drives the trapezoidal slider to move. When the fixing frame drives the wire spool to move to the position of the wire feeding device, the control button is pressed by the fixing plate, thereby starting the electric slide rail to drive one end of the wire to move into the wire feeding device, feeding the wire into the wire feeding device, improving the welding efficiency of the welding device.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1 to 13 , a metal steel part welding device, including an installation platform 1, on one side of the upper surface of the installation platform 1, a welding robot arm 3 is provided, on both sides of the upper surface of the installation platform 1 close to the welding robot arm 3, clamping devices 2 are provided, on the lower side of the outer circumferential surface of the welding robot arm 3, on the side far from the clamping device 2, a wire feeding device 11 is fixedly connected, on the outer surface of the installation platform 1, on the side close to the welding robot arm 3, a replacement component 4 is provided;

[0045] The replacement component 4 includes a replacement box 41 fixedly connected to the outer surface of the installation platform 1 on the side close to the welding robot arm 3. Inside the replacement component 4, a rectangular electric slide rail 42 is provided, and one side of the rectangular electric slide rail 42 penetrates through the upper surface of the replacement box 41. Inside the rectangular electric slide rail 42, several evenly distributed fixed frames 43 are slidably connected, and the wire spool is placed inside the fixed frame 43.

[0046] Such as Figure 2 , Figure 3 , Figure 4As shown in the figure, six fixing brackets 43 are provided. On the upper sides of both sides of the inner wall of the fixing bracket 43, first sliding grooves 44 are opened. Inside both of the first sliding grooves 44, sliding positioning blocks 45 are slidably connected. On the sides of the inner walls of both of the first sliding grooves 44 away from the sliding positioning blocks 45, L-shaped sliding grooves 46 are opened. Inside both of the L-shaped sliding grooves 46, L-shaped sliding blocks 47 are slidably connected. On the side of the outer surface of the sliding positioning block 45 close to the L-shaped sliding block 47, a fixing seat 48 is fixedly connected. On the upper ends of both of the L-shaped sliding blocks 47, connecting plates 49 are rotatably connected. And on the other ends of both of the connecting plates 49, they are rotatably connected to the fixing seat 48. On both sides of the inner wall of the fixing bracket 43, directly below the first sliding grooves 44, second sliding grooves 410 are opened. Inside both of the second sliding grooves 410, first connecting blocks 411 are slidably connected. On the lower surfaces of both of the L-shaped sliding blocks 47, first connecting rods 412 are fixedly connected. And the lower ends of both of the first springs 413 extend into the second sliding grooves 410 and are fixedly connected to the first connecting blocks 411.

[0047] As Figure 2 , Figure 3 shown in the figure, a second connecting rod 414 is fixedly connected between both of the first connecting blocks 411. On the lower surfaces of both of the L-shaped sliding blocks 47, first springs 413 are provided. And both of the first connecting rods 412 respectively pass through both of the first springs 413. At the middle position on the outer surface of the replacement box 41 away from one side of the welding robotic arm 3, a discharge slide 415 is fixedly connected. And the welding robotic arm 3, the discharge slide 415, and one fixing bracket 43 are on the same straight line.

[0048] As Figure 1 , Figure 2 shown in the figure, on the upper surface of the installation platform 1, at the middle position between the two clamping devices 2, a supporting device 9 is provided. On the sides of both of the clamping devices 2 away from each other, a rotating device 10 is provided. On the lower side of the outer cylindrical surface of the welding robotic arm 3, an air inlet pipe 12 is fixedly connected.

[0049] When in use, first place the two metal steel parts in the clamping devices 2 on both sides respectively, then start the clamping devices 2 on both sides to clamp and fix the two metal steel parts at the same time, and then start the supporting device 9 to clamp the contact position of the two metal steel parts, so as to keep the two metal steel parts in the same straight line, prevent the contact positions of the two metal steel parts from being staggered, and affect the quality of the two metal steel parts after welding, and then start the welding robot 3 to weld the contact position of the two metal steel parts, and at the same time start the rotating device 10 to drive the two metal steel parts to rotate at the same time, so as to fully weld the contact positions of the two metal steel parts, and then weld the two metal steel parts together, and the welding wire can be transported to the inside of the welding robot 3 through the wire feeding device 11 to ensure the welding efficiency of the welding device, and at the same time, the protective gas can be blown to the welding position of the two metal steel parts by the air inlet pipe 12, so as to protect the molten pool from the influence of oxygen, nitrogen and water vapor in the air during the welding process, prevent metal oxidation and contamination, and ensure the quality of the welded joint.

[0050] However, when the welding wire on the wire spool is used up, it is necessary to manually replace the wire spool to ensure the welding efficiency of the welding device. However, when replacing the wire spool, novice workers with unskilled operations often take more time than skilled workers, reducing the welding efficiency of the welding device. Therefore, a replacement component 4 is provided. First, the wire spool is placed in the fixing frame 43. Under the weight of the wire spool itself, it drives two first connecting blocks 411 to move downward in the second sliding groove 410, and then drives the L-shaped slider 47 to move downward in the L-shaped sliding groove 46 through the first connecting rod 412. Then, through the cooperation of the connecting plate 49 and the fixing seat 48, it drives the sliding positioning block 45 to move outward in the first sliding groove 44, so that the two sliding positioning blocks 45 are inserted into both ends of the wire spool, thereby restricting the wire spool inside the fixing frame 43. At the same time, the wire spool can rotate inside the fixing frame 43, facilitating the extraction of the welding wire on the wire spool. And when the welding wire on the wire spool is used up, the weight of the wire spool decreases, and then the L-shaped slider 47 is driven to move upward by the first spring 413. Then, through the cooperation of the connecting plate 49 and the fixing seat 48, the sliding positioning block 45 is driven to move inside the first sliding groove 44, thereby releasing the restriction on the wire spool. At the same time, the first connecting block 411 is driven to move upward, ejecting the wire spool from the fixing frame 43 onto the discharge slide 415, and discharging the used wire spool through the discharge slide 415. Then, the square-shaped electric slide rail 42 is started to drive the fixing frame 43 to move, thereby driving a new wire spool to move to the position of the wire feeding device 11. Then, manually extract one end of the welding wire on the wire spool and insert it into the wire feeding device 11, and thus the replacement of the wire spool can be quickly completed, improving the welding efficiency of the welding device. And the two first connecting blocks 411 are connected together by the second connecting rod 414, thereby ensuring the simultaneous movement of the two sliding positioning blocks 45 and enabling the two sliding positioning blocks 45 to stably restrict the wire spool.

[0051] As Figure 3 、 Figure 5 、 Figure 6 As shown, one side of the inner wall of the fixing frame 43 is provided with an ejection component 5. The ejection component 5 includes third sliding grooves 51 opened at both ends of the lower side of the inner wall of the fixing frame 43. Two ejection plates 52 are slidably connected inside the two third sliding grooves 51. Two second springs 53 are arranged on the lower surfaces of the two ejection plates 52.

[0052] As Figure 6 、 Figure 7As shown, above the two second chutes 410 inside the fixing frame 43, fourth chutes 54 are respectively provided. Inside the two fourth chutes 54, first sliders 55 are slidably connected. On the upper surface of the two ejector plates 52, grooves 58 are respectively provided on one side close to the fourth chutes 54. On one side of the outer surfaces of the two first sliders 55, first straight rods 57 are respectively fixedly connected, and one end of each of the two first straight rods 57 is inserted into the inside of the corresponding groove 58. On the side of the outer surfaces of the two first sliders 55 away from the first straight rods 57, third springs 56 are respectively provided. On the lower surfaces of the two first sliders 55, first trapezoidal grooves 59 are respectively provided. At the lower ends of the inner walls of the two fourth chutes 54, fifth chutes 510 are respectively provided. Inside the two fifth chutes 510, first trapezoidal blocks 511 are slidably connected, and the upper ends of the two first trapezoidal blocks 511 are respectively inserted into the two first trapezoidal grooves 59. On the lower surfaces of the two first trapezoidal blocks 511, second straight rods 512 are respectively fixedly connected, and the two second straight rods 512 respectively extend into the second chutes 410.

[0053] In the above-mentioned embodiment, when the wire spool is placed into the fixing frame 43, and then restricted in the fixing frame 43 by the weight of the wire spool itself. When the wire on the wire spool is used up, the sliding positioning block 45 is driven by the first spring 413 to retract into the first chute 44, and at the same time, the first connecting block 411 is driven to move upward, so as to eject the used wire spool into the discharge slide 415. However, because the first connecting block 411 is located directly below the wire spool, when the first connecting block 411 moves upward, it cannot accurately push the wire spool towards the position of the discharge slide 415, reducing the use effect of the replacement component 4.

[0054] Therefore, the ejecting component 5 is provided. When the first connecting block 411 pushes the wire spool to move upward, by pushing the second straight rod 512 to move upward, the first trapezoidal block 511 is enabled to insert into the first trapezoidal groove 59, thereby driving the first slider 55 to move in the fourth chute 54. At the same time, the first straight rod 57 is driven to be withdrawn from the inside of the groove 58, releasing the fixation of the ejector plate 52. Then, the second spring 53 drives the ejector plate 52 to move upward in the third chute 51, so as to push the wire spool upward on the side of the fixing frame 43 away from the discharge slide 415, and then accurately push the wire spool into the discharge slide 415, improving the use effect of the replacement component 4.

[0055] Such as Figure 2 、 Figure 8As shown, on the side of the upper surface of the discharge slide 415 away from the replacement box 41, an alarm component 6 is provided. The alarm component 6 includes a pressure sensor 61 fixedly connected to the inner wall of the discharge slide 415 on the side away from the replacement box 41. On the side of the upper surface of the discharge slide 415 close to the pressure sensor 61, a single-chip microcomputer 62 is fixedly connected, and the single-chip microcomputer 62 is electrically connected to the pressure sensor 61. On the side of the upper surface of the discharge slide 415 close to the single-chip microcomputer 62, a controller 63 is fixedly connected, and the controller 63 is electrically connected to the single-chip microcomputer 62 and the square-shaped electric slide rail 42. On the side of the upper surface of the discharge slide 415 close to the controller 63, an alarm lamp 64 is fixedly connected, and the alarm lamp 64 is electrically connected to the controller 63.

[0056] As Figure 2 , Figure 8 , Figure 9 shown, on the side of the outer surface of the replacement box 41 close to the discharge slide 415, a feeding component 7 is provided. The feeding component 7 includes a feeding port 71 opened on one side of the outer surface of the replacement box 41 on the side of the discharge slide 415, and the feeding port 71 extends into the square-shaped electric slide rail 42. At the position corresponding to the feeding port 71 on one side of the outer surface of the replacement box 41, a feeding slide 72 is fixedly connected. Above the feeding port 71 on one side of the outer surface of the replacement box 41, a U-shaped frame 73 is fixedly connected. A baffle 74 is slidably connected inside the U-shaped frame 73. A circular through-hole 75 is opened on one side of the outer surface of the baffle 74. A runner 77 is arranged inside the circular through-hole 75. On one side of the outer surface of the U-shaped frame 73, a motor 76 is fixedly connected. The output end of the motor 76 penetrates the U-shaped frame 73 and is fixedly connected to the runner 77, and the output end of the motor 76 is fixed to a position on the outer surface of the runner 77 away from the center of the runner 77.

[0057] In the above embodiment, through the replacement component 4 and the ejection component 5, after the welding wire on the welding wire reel is used up, the welding wire reel is automatically replaced, improving the welding efficiency of the welding device. However, after the used-up welding wire reel in the fixed frame 43 is discharged, the replacement box 41 cannot be started in time to move the new welding wire reel to the position of the wire feeding device 11, reducing the working efficiency of the replacement component 4. Therefore, the alarm component 6 is provided. When the welding wire reel is discharged into the discharge slide 415 and moves down to the bottom in the discharge slide 415, the pressure sensor 61 senses that the welding wire reel moves to the bottom of the discharge slide 415. Then, the pressure sensor 61 transmits an electrical signal to the single-chip microcomputer 62 for processing, and then transmits the processed electrical signal to the controller 63 for processing. Finally, the square-shaped electric slide rail 42 is started to drive the fixed frame 43 to move, so as to move the new welding wire reel to the position of the wire feeding device 11, thereby replacing the new welding wire reel in time after the welding wire on the welding wire reel is used up, improving the working efficiency of the replacement component 4.

[0058] In the above embodiments, the fixed frame 43 is driven to move by the square-shaped electric slide rail 42, thereby driving the wire spool to move. At the same time, the used wire spool is accurately pushed into the discharge slide 415 by the ejection assembly 5, and then the new wire spool is timely moved below the wire feeding device 11 by the alarm assembly 6. However, when the replacement assembly 4 is in use, the worker still needs to manually place the new wire spool into the fixed frame 43, so that the replacement assembly 4 can move the new wire spool below the wire feeding device 11 to complete the replacement of the wire spool, which reduces the welding efficiency of the welding device.

[0059] Therefore, a feeding assembly 7 is provided. Several new wire spools are placed into the feeding slide 72, and then the baffle 74 is pushed downward by the center of the rotating wheel 77 moving downward, thereby blocking the wire spool from moving downward. Then, after the alarm assembly 6 controls the square-shaped electric slide rail 42 to drive the fixed frame 43 to move, the motor 76 is started to drive the rotating wheel 77 to rotate one circle around the output shaft of the motor 76 inside the circular through hole 75. When the center of the rotating wheel 77 rotates upward, the wire spool moves downward in the feeding slide 72 by its own weight, and at the same time, it can push the baffle 74 to move upward in the U-shaped frame 73, so that the new wire spool enters the square-shaped electric slide rail 42 through the feeding port 71 and falls into the fixed frame 43, thereby automatically placing the wire spool into the fixed frame 43, facilitating the replacement assembly 4 to move the new wire spool below the wire feeding device 11 to complete the replacement of the wire spool, improving the welding efficiency of the welding device. Then, when the center of the rotating wheel 77 rotates downward, it can block other wire spools from continuing to move downward, so that only one wire spool can enter the square-shaped electric slide rail 42 and be placed into the fixed frame 43 at a time, improving the use effect of the feeding assembly 7.

[0060] As Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown in

[0061] AsFigure 12 , Figure 13 As shown, on one side of the outer surface of the trapezoidal slider 83 close to the fixed frame 43, a sixth chute 89 is provided. A third slider 810 is slidably connected inside the sixth chute 89. On one side of the outer surface of the third slider 810 close to the fixed frame 43, a positioning rod 811 is fixedly connected, and the positioning rod 811 penetrates the trapezoidal slider 83. At positions corresponding to the positioning rod 811 on one side of the outer surface of the fixed frame 43, positioning holes 812 are provided, and the positioning rod 811 is inserted into the positioning holes 812. On the side of the outer surface of the third slider 810 away from the positioning rod 811, a fourth spring 813 is provided. On one side of the outer surface of the third slider 810, a second trapezoidal groove 814 is provided. On one side of the inner wall of the sixth chute 89, a seventh chute 815 is provided. A second trapezoidal block 816 is slidably connected inside the seventh chute 815, and one end of the second trapezoidal block 816 extends into the second trapezoidal groove 814. On the side of the outer surface of the second trapezoidal block 816 away from the second trapezoidal groove 814, a third straight rod 817 is fixedly connected, and the third straight rod 817 and the control button 88 are on the same side.

[0062] In the above embodiment, the fixed frame 43 is driven to move by the square-shaped electric slide rail 42, thereby driving the wire spool to move. When the wire spool in one fixed frame 43 is used up, the fixed frame 43 is timely driven to move by the square-shaped electric slide rail 42, and a new wire spool is moved to the lower part of the wire feeding device 11 by another fixed frame 43. However, it is still necessary for the worker to manually draw out the wire of the wire spool and insert the wire into the wire feeding device 11, so as to facilitate the wire to enter the welding robot arm 3 for welding work, reducing the welding efficiency of the welding device.

[0063] Therefore, an insertion component 8 is provided. The fourth spring 813 drives the third slider 810 to move within the sixth chute 89, thereby driving the positioning rod 811 to insert into the positioning hole 812, fixedly connecting the trapezoidal slider 83 to the fixed frame 43. Then, the welding wire on the wire reel within the fixed frame 43 is drawn out, and one end of the welding wire is passed through the two groups of limiting pinch rollers 87, thereby clamping one end of the welding wire. When the fixed frame 43 drives the wire reel towards the wire feeding device 11, it simultaneously drives the trapezoidal slider 83 to slide on the two fixed sliding rods 82. When the fixed frame 43 drives the wire reel to move to the position of the wire feeding device 11, the control button 88 is pressed through the fixed plate 81, thereby starting the electric slide rail 84 to drive the second slider 85 to move. Then, through the L-shaped frame 86 and the two groups of limiting pinch rollers 87, one end of the welding wire is driven to move into the wire feeding device 11, and the two groups of limiting pinch rollers 87 are rotatably connected to the L-shaped frame 86, enabling the welding wire to move within the two groups of limiting pinch rollers 87, thereby facilitating the entry of the welding wire into the wire feeding device 11 and improving the welding efficiency of the welding device. At the same time, the fixed plate 81 pushes the third straight rod 817 to drive the second trapezoidal block 816 to move into the second trapezoidal groove 814, thereby driving the third slider 810 to move, and further driving the positioning rod 811 to be withdrawn from the positioning hole 812, releasing the fixed connection between the trapezoidal slider 83 and the fixed frame 43.

[0064] Usage method: First, manually drive the trapezoidal slider 83 to move away from the wire feeding device 11, such that the trapezoidal slider 83 moves to the position of the fixed frame 43 on one side. Then, the fourth spring 813 drives the positioning rod 811 to insert into the positioning hole 812, thereby fixing the trapezoidal slider 83 to the fixed frame 43. When the welding wire on the wire reel is used up, the two sliding positioning blocks 45 are driven by the first spring 413 to retract into the first chute 44, simultaneously driving the first connecting block 411 to move upward, thereby pushing the used-up wire reel upward, and simultaneously pushing the second straight rod 512 upward, thereby starting the ejection component 5, driving the ejection plate 52 to move upward, and further pushing the used-up wire reel towards the discharge slide 415. When the used-up wire reel moves to the bottom of the discharge slide 415, the alarm component 6 is started, thereby controlling the start of the square-shaped electric slide rail 42, driving the fixed frame 43 to drive a new wire reel towards the wire feeding device 11, and simultaneously driving the trapezoidal slider 83 to move. After the fixed frame 43 moves to the position of the wire feeding device 11, the square-shaped electric slide rail 42 is stopped, and at the same time, the control button 88 is pressed through the fixed plate 81 to start the electric slide rail 84, driving the welding wire to insert into the wire feeding device 11, and simultaneously pushing the third straight rod 817 to drive the positioning rod 811 to be withdrawn from the positioning hole 812, releasing the fixed connection between the trapezoidal slider 83 and the fixed frame 43. Then, the feeding component 7 is started, such that the wire reel can move downward within the feeding slide 72, and further fall into the fixed frame 43.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
