Description

Technical Field

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

[0002] Metal steel parts refer to various parts and components made of metal materials, especially steel. When processing metal parts, metal parts need to be welded. Therefore, a metal steel welding device is needed. It is usually composed of electric welding tongs, wire feeding mechanism and power supply. It generates high temperature through arc discharge, melts the metal and solidifies it into a weld, thereby realizing the connection of metals. Its working principle is based on arc welding technology. When current passes through the electrode and the workpiece, the arc generates high temperature, melts the contact point, and then fills the solder to form a weld. The wire feeding mechanism in the device is responsible for providing welding wire, which is melted by arc heating and filled into the weld to complete the welding process. It is widely used in sheet metal processing in the automotive, shipbuilding, aviation and other industries.

[0003] When using an existing welding device, the metal steel piece is fixed by a clamping device, and then the welding device is started to weld the contact position of the metal steel piece. At the same time, the wire feeding device is started to continuously feed the welding wire into the welding device, thereby ensuring that the welding device can continuously weld the metal steel piece, thereby improving the welding efficiency of the welding device. However, when the welding wire in the wire reel is used up, the wire reel needs to be replaced manually to ensure the welding efficiency of the welding device. However, when replacing the wire reel, unskilled novice workers often need to spend more time than skilled workers, which can easily affect the welding efficiency of the metal steel piece and reduce the welding efficiency of the welding device.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (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.

[0017] (2) The present application sets up an ejector assembly. When the No. 1 connecting block pushes the wire reel upward, the No. 2 straight rod is pushed upward at the same time, thereby pulling the No. 1 straight rod out from the groove and releasing the fixation of the ejector plate. Then, the ejector plate is driven to move upward in the No. 3 slide groove by the No. 2 spring, thereby pushing the wire reel upward on the side of the fixed frame away from the discharge slide, and then accurately pushing the wire reel into the discharge slide, thereby improving the use effect of the replacement assembly.

[0018] (3) The present application sets a feeding assembly, puts several new welding wire reels into the feeding slide, and pushes the baffle plate downward with the center of the wheel pointing downward, thereby blocking the welding wire reels from moving downward. Then, the wheel rotates inside the circular opening, and when the center of the wheel rotates upward, the welding wire reels move downward in the feeding slide due to their own weight and fall into the fixed frame, thereby automatically placing the welding wire reels into the fixed frame, completing the replacement of the welding wire reels, and improving the welding efficiency of the welding device.

[0019] (4) The present application sets an insertion component, drives the positioning rod to be inserted into the positioning hole through the No. 4 spring, and fixes the trapezoidal slider to the fixed frame. Then the welding wire on the wire reel in the fixed frame is pulled out, and one end of the welding wire is passed through two sets of limit clamping rollers to clamp one end of the welding wire. When the fixed frame drives the welding wire reel to move in the direction of the wire feeding device, it also drives the trapezoidal slider to move. When the fixed frame drives the welding wire reel to the position of the wire feeding device, the control button is pressed through the fixed plate, thereby starting the electric slide rail to drive one end of the welding wire to move into the wire feeding device, and the welding wire enters the wire feeding device, thereby improving the welding efficiency of the welding device.

The upper ends of the two connecting plates 49 are rotatably connected, and the other ends of the two connecting plates 49 are rotatably connected to the fixed seat 48, and No. 2 slide grooves 410 are provided on both sides of the inner wall of the fixed frame 43 directly below the No. 1 slide groove 44, and the two No. 2 slide grooves 410 are slidably connected to the No. 1 connecting blocks 411, the lower surfaces of the two L-shaped sliding blocks 47 are fixedly connected to the No. 1 connecting rod 412, and the lower ends of the two No. 1 springs 413 extend to the No. 2 slide grooves 410 and are fixedly connected to the No. 1 connecting blocks 411.

[0025] like Figure 2 , Figure 3 As shown, a No. 2 connecting rod 414 is fixedly connected between the two No. 1 connecting blocks 411, a No. 1 spring 413 is provided on the lower surfaces of the two L-shaped sliders 47, and the two No. 1 connecting rods 412 pass through the two No. 1 springs 413 respectively, and a discharge slide 415 is fixedly connected to the middle position of the outer surface of the replacement box 41 away from the side of the welding robot arm 3, and the welding robot arm 3, the discharge slide 415 and a fixed frame 43 are in the same straight line.

[0026] like Figure 1 , Figure 2 As shown, a supporting device 9 is provided on the upper surface of the mounting platform 1 at the middle position of the two clamping devices 2, a rotating device 10 is provided on the side of the two clamping devices 2 away from each other, and an air intake pipe 12 is fixedly connected to the lower side of the outer cylindrical surface of the welding robot arm 3.

[0027] 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.

[0028] However, when the welding wire in the welding wire reel is used up, it is necessary to manually replace the welding wire reel to ensure the welding efficiency of the welding device. However, when replacing the welding wire reel, unskilled novice workers often need to spend more time than skilled workers, which reduces the welding efficiency of the welding device. Therefore, a replacement component 4 is set up, firstly, the welding wire reel is placed in the fixed frame 43, and under the weight of the welding wire reel itself, the two No. 1 connecting blocks 411 are driven to move downward in the No. 2 slide groove 410, and then the No. 1 connecting rod 412 drives the L-shaped slider 47 to move downward in the L-shaped slide groove 46, and then the sliding positioning block 45 is driven to move outward in the No. 1 slide groove 44 through the cooperation of the connecting plate 49 and the fixed seat 48, so that the two sliding positioning blocks 45 are inserted into the two ends of the welding wire reel, and then the welding wire reel is restricted in the fixed frame 43, and at the same time, the welding wire reel can be rotated in the fixed frame 43, so that the welding wire on the welding wire reel is easy to be drawn out, and when the welding wire on the welding wire reel is used up, the weight of the welding wire reel decreases, and then through the The No. 1 spring 413 drives the L-shaped slider 47 to move upward, and then drives the sliding positioning block 45 to move inside the No. 1 slide groove 44 through the cooperation of the connecting plate 49 and the fixing seat 48, thereby releasing the restriction on the welding wire reel, and at the same time drives the No. 1 connecting block 411 to move upward, ejecting the welding wire reel from the fixing frame 43 to the discharge slide 415, and discharges the used welding wire reel through the discharge slide 415, and then starts the U-shaped electric slide rail 42 to drive the fixing frame 43 to move, thereby driving the new welding wire reel to move to the position of the wire feeding device 11, and then manually extracts one end of the welding wire on the welding wire reel and inserts it into the wire feeding device 11, so that the replacement of the welding wire reel can be completed quickly, thereby improving the welding efficiency of the welding device. And the two No. 1 connecting blocks 411 are connected together by the No. 2 connecting rod 414, thereby ensuring the simultaneous movement of the two sliding positioning blocks 45, so that the two sliding positioning blocks 45 stably restrict the welding wire reel.

[0029] like Figure 3 , Figure 5 , Figure 6 As shown, an ejection assembly 5 is provided on one side of the inner wall of the fixed frame 43, and the ejection assembly 5 includes a No. 3 slide groove 51 opened at both ends of the lower side of the inner wall of the fixed frame 43, and the two No. 3 slide grooves 51 are both slidably connected with an ejection plate 52, and the lower surfaces of the two ejection plates 52 are provided with two No. 2 springs 53.

[0030] like Figure 6 , Figure 7As shown, a No. 4 slide groove 54 is provided inside the fixing frame 43 above the two No. 2 slide grooves 410, and a No. 1 slider 55 is slidably connected inside the two No. 4 slide grooves 54. A groove 58 is provided on the upper surface of the two ejection plates 52 near the No. 4 slide groove 54. A No. 1 straight rod 57 is fixedly connected to one side of the outer surface of the two No. 1 sliders 55, and one end of the two No. 1 straight rods 57 is inserted into the groove 58. A No. 1 slider 55 is provided on the outer surface away from the No. 1 straight rod 57. A No. 3 spring 56 is arranged, and a No. 1 trapezoidal groove 59 is provided on the lower surface of the two No. 1 sliding blocks 55, and a No. 5 sliding groove 510 is provided on the lower end of the inner wall of the two No. 4 sliding grooves 54. The two No. 5 sliding grooves 510 are slidably connected with No. 1 trapezoidal blocks 511, and the upper ends of the two No. 1 trapezoidal blocks 511 are respectively inserted into the two No. 1 trapezoidal grooves 59, and the lower surfaces of the two No. 1 trapezoidal blocks 511 are fixedly connected with No. 2 straight rods 512, and the two No. 2 straight rods 512 extend to the interior of the No. 2 sliding groove 410 respectively.

[0031] In the above embodiment, the welding wire reel is placed in the fixing frame 43 and then restricted in the fixing frame 43 by the weight of the welding wire reel itself. When the welding wire on the welding wire reel is used up, the sliding positioning block 45 is driven by the No. 1 spring 413 to be received into the No. 1 slide groove 44, and the No. 1 connecting block 411 is driven to move upward at the same time, so as to push the used welding wire reel into the discharge slide 415. However, because the No. 1 connecting block 411 is located directly below the welding wire reel, the No. 1 connecting block 411 cannot accurately push the welding wire reel to the position of the discharge slide 415 when it moves upward, thereby reducing the use effect of the replacement component 4.

[0032] Therefore, an ejection assembly 5 is provided. When the No. 1 connecting block 411 pushes the welding wire reel to move upward, the No. 2 straight rod 512 is pushed upward, so that the No. 1 trapezoidal block 511 is inserted into the No. 1 trapezoidal groove 59, thereby driving the No. 1 slider 55 to move in the No. 4 slide groove 54, and at the same time driving the No. 1 straight rod 57 to be pulled out from the inside of the groove 58, releasing the fixation of the ejection plate 52, and then driving the ejection plate 52 to move upward in the No. 3 slide groove 51 through the No. 2 spring 53, thereby pushing the welding wire reel upward on the side of the fixing frame 43 away from the discharge slide 415, and then accurately pushing the welding wire reel into the discharge slide 415, thereby improving the use effect of the replacement assembly 4.

[0033] like Figure 2 , Figure 8As shown, an alarm component 6 is provided on the side of the upper surface of the discharge slide 415 away from the replacement box 41, and the alarm component 6 includes a pressure sensor 61 fixedly connected to the side of the inner wall of the discharge slide 415 away from the replacement box 41, a single-chip computer 62 is fixedly connected to the side of the upper surface of the discharge slide 415 close to the pressure sensor 61, and the single-chip computer 62 is electrically connected to the pressure sensor 61, a controller 63 is fixedly connected to the side of the upper surface of the discharge slide 415 close to the single-chip computer 62, and the controller 63 is electrically connected to the single-chip computer 62 and the U-shaped electric slide rail 42, and an alarm light 64 is fixedly connected to the side of the upper surface of the discharge slide 415 close to the controller 63, and the alarm light 64 is electrically connected to the controller 63.

[0034] like Figure 2 , Figure 8 , Fig. 9 As shown, a loading assembly 7 is provided on one side of the outer surface of the replacement box 41 close to the discharge slide 415, and the loading assembly 7 includes a loading port 71 opened on one side of the outer surface of the replacement box 41 and located on one side of the discharge slide 415, and the loading port 71 extends to the inside of the U-shaped electric slide rail 42, and a loading slide 72 is fixedly connected to a position corresponding to the loading port 71 on one side of the outer surface of the replacement box 41, and a U-shaped frame 73 is fixedly connected to one side of the outer surface of the replacement box 41 above the loading port 71, and a baffle 74 is slidably connected to the inside of the U-shaped frame 73, and a circular opening 75 is opened on one side of the outer surface of the baffle 74, and a rotating wheel 77 is arranged inside the circular opening 75, and a motor 76 is fixedly connected to one side of the outer surface of the U-shaped frame 73, and the output end of the motor 76 passes through the U-shaped frame 73 and is fixedly connected to the rotating wheel 77, and the output end of the motor 76 is fixed to a position on the outer surface of the rotating wheel 77 away from the center of the rotating wheel 77.

[0035] In the above embodiment, the replacement component 4 and the ejection component 5 are used up, and the welding wire reel is automatically replaced after the welding wire on the welding wire reel is used up, thereby improving the welding efficiency of the welding device. However, after the used 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, which reduces the working efficiency of the replacement component 4. Therefore, an alarm component 6 is set. After the welding wire reel is discharged into the discharge slide 415 and moves downward 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, and then the pressure sensor 61 transmits the electrical signal to the single-chip microcomputer 62 for processing, and then transmits the processed electrical signal to the controller 63 for processing, and finally starts the U-shaped electric slide rail 42 to drive the fixed frame 43 to move, thereby moving the new welding wire reel to the position of the wire feeding device 11, so that after the welding wire on the welding wire reel is used up, the new welding wire reel is replaced in time, thereby improving the working efficiency of the replacement component 4.

[0036] In the above embodiment, the fixed frame 43 is driven to move by the U-shaped electric slide rail 42, thereby driving the wire reel to move, and at the same time, the used wire reel is accurately pushed into the discharge slide 415 through the ejection component 5, and then the new wire reel is promptly moved to the bottom of the wire feeding device 11 through the alarm component 6. However, when the replacement component 4 is in use, the worker still needs to manually put the new wire reel into the fixed frame 43, so that the replacement component 4 can move the new wire reel to the bottom of the wire feeding device 11 to complete the replacement of the wire reel, thereby reducing the welding efficiency of the welding device.

[0037] Therefore, a feeding assembly 7 is set up, and several new welding wire reels are placed in the feeding slide 72. Then, the center of the rotating wheel 77 is downward, pushing the baffle 74 to move downward, thereby blocking the welding wire reel from moving downward. Then, when the alarm assembly 6 controls the U-shaped electric slide 42 to drive the fixed frame 43 to move, the motor 76 is started to drive the rotating wheel 77 to rotate around the output shaft of the motor 76 inside the circular opening 75. When the center of the rotating wheel 77 rotates upward, the welding wire reel moves downward in the feeding slide 72 by its own weight, and at the same time, the baffle 74 can be pushed upward in the U-shaped frame 73. Move, so that the new welding wire reel enters the U-shaped electric slide rail 42 through the loading port 71 and falls into the fixed frame 43, thereby automatically placing the welding wire reel into the fixed frame 43, which is convenient for replacing the component 4 to move the new welding wire reel to the bottom of the wire feeding device 11, complete the replacement of the welding wire reel, and improve the welding efficiency of the welding device. Then, when the center of rotation of the rotating wheel 77 is downward, other welding wire reels can be blocked from continuing to move downward, so that only one welding wire reel can enter the U-shaped electric slide rail 42 at a time and be placed in the fixed frame 43, thereby improving the use effect of the loading component 7.

[0038] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, an insertion component 8 is provided on the upper surface of the replacement box 41 between the U-shaped electric slide rail 42 and the welding robot arm 3, and the insertion component 8 includes two fixed plates 81 fixedly connected to the position on the upper surface of the replacement box 41 between the U-shaped electric slide rail 42 and the welding robot arm 3, two fixed slide rods 82 are fixedly connected between the two fixed plates 81, a trapezoidal slider 83 is provided between the two fixed plates 81, and the two fixed slide rods 82 both penetrate the trapezoidal slider 83, an electric slide rail 84 is provided on one side of the upper surface of the trapezoidal slider 83, a second slider 85 is slidably connected inside the electric slide rail 84, an L-shaped frame 86 is fixedly connected to the upper surface of the second slider 85, and two groups of limiting clamping rollers 87 are rotatably connected to one side of the inner wall of the L-shaped frame 86, a control button 88 is fixedly connected to the outer surface of the trapezoidal slider 83 near the middle position of the replacement box 41, and the control button 88 is electrically connected to the electric slide rail 84.

[0039] like Fig.12 , Fig.13 As shown, a sixth slide groove 89 is provided on the outer surface of the trapezoidal slider 83 near the fixed frame 43, and a third slider 810 is slidably connected inside the sixth slide groove 89. A positioning rod 811 is fixedly connected to the outer surface of the third slider 810 near the fixed frame 43, and the positioning rod 811 penetrates the trapezoidal slider 83. Positioning holes 812 are provided at positions corresponding to the positioning rod 811 on one side of the outer surface of the fixed frame 43, and the positioning rod 811 is inserted into the positioning hole 812. The outer surface of the third slider 810 is away from the positioning rod. A No. 4 spring 813 is provided on one side of 811, a No. 2 trapezoidal groove 814 is provided on one side of the outer surface of the No. 3 sliding block 810, a No. 7 sliding groove 815 is provided on one side of the inner wall of the No. 6 sliding groove 89, a No. 2 trapezoidal block 816 is slidably connected inside the No. 7 sliding groove 815, and one end of the No. 2 trapezoidal block 816 extends into the No. 2 trapezoidal groove 814, a No. 3 straight rod 817 is fixedly connected to the side of the outer surface of the No. 2 trapezoidal groove 814 away from the No. 2 trapezoidal groove 814, and the No. 3 straight rod 817 and the control button 88 are located on the same side.

[0040] In the above embodiment, the fixed frame 43 is driven to move by the U-shaped electric slide rail 42, thereby driving the wire reel to move, so that after the wire reel in one fixed frame 43 is used up, the fixed frame 43 is driven to move by the U-shaped electric slide rail 42 in time, and a new wire reel is moved to the bottom of the wire feeding device 11 through another fixed frame 43. However, the worker is still required to manually extract the welding wire from the wire reel and insert the welding wire into the wire feeding device 11, so as to facilitate the welding wire to enter the welding robot arm 3 for welding work, which reduces the welding efficiency of the welding device.

[0041] Therefore, an insertion assembly 8 is provided, and the No. 3 slider 810 is driven to move in the No. 6 slide groove 89 by the No. 4 spring 813, thereby driving the positioning rod 811 to be inserted into the positioning hole 812, and the trapezoidal slider 83 is fixedly connected to the fixing frame 43, and then the welding wire on the welding wire reel in the fixing frame 43 is pulled out, and then one end of the welding wire is passed through the two sets of limit clamping rollers 87, so as to clamp one end of the welding wire. When the fixing frame 43 drives the welding wire reel to move in the direction of the wire feeding device 11, the trapezoidal slider 83 is driven at the same time between the two fixed slide rods 82 When the fixed frame 43 drives the welding 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, and then the L-shaped frame 86 and the two sets of limit clamping rollers 87 drive one end of the welding wire to move into the wire feeding device 11, and the two sets of limit clamping rollers 87 are rotatably connected with the L-shaped frame 86, so that the welding wire can move in the two sets of limit clamping rollers 87, thereby facilitating the welding wire to enter 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 then driving the positioning rod 811 to be pulled out from the positioning hole 812, releasing the fixed connection between the trapezoidal slider 83 and the fixed frame 43.

[0042] Method of use: First, manually drive the trapezoidal slider 83 to move away from the wire feeding device 11, so that the trapezoidal slider 83 moves to the position of the fixed frame 43 on one side, and then drive the positioning rod 811 to insert into the positioning hole 812 through the No. 4 spring 813, so as to fix the trapezoidal slider 83 with the fixed frame 43. When the welding wire in the welding wire reel is used up, the No. 1 spring 413 drives the two sliding positioning blocks 45 to be received into the No. 1 slide groove 44, and at the same time drives the No. 1 connecting block 411 to move upward, thereby pushing the used welding wire reel to move upward, and at the same time pushes the No. 2 straight rod 512 to move upward, thereby starting the ejection assembly 5, driving the ejection plate 52 to move upward, and then pushing the used welding wire reel to move toward the discharge slide 415. When the used welding wire reel moves to the bottom of the discharge slide 415, the alarm assembly 6 is started, thereby controlling the U-shaped electric slide rail 42 to start, driving the fixed frame 43 to drive the new welding wire reel to move toward the wire feeding device 11, and at the same time driving the trapezoidal slider 83 to move. When the fixed frame 43 moves to the position of the wire feeding device 11, the U-shaped electric slide rail 42 is stopped, and the control button 88 is pressed through the fixed plate 81 to start the electric slide rail 84, driving the welding wire to be inserted into the wire feeding device 11, and at the same time, the third straight rod 817 is pushed to drive the positioning rod 811 to be pulled out from the positioning hole 812, thereby releasing the fixed connection between the trapezoidal slider 83 and the fixed frame 43. Then, the feeding assembly 7 is started, so that the welding wire reel can move downward in the feeding slide 72 and then fall into the fixed frame 43.
