Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy welding, and specifically to a rapid positioning welding device for aluminum profile processing. Background Art

[0002] Aluminum alloy profiles are one of the most widely used non-ferrous metal structural materials in industry. Common processing of aluminum alloy profiles includes welding. Among them, after splicing multiple sections of aluminum alloy profiles into a rectangle, welding the splicing joints is a common welding method.

[0003] The prior art discloses a Chinese patent with the application number CN202411845188.X, an aluminum alloy door and window seamless welding system, which discloses that two groups of welding torches are provided, and each group of welding torches is arranged vertically and horizontally. An adjustable guide rail based on a positioning mechanism is provided. Thus, during the process of moving in a single direction, through the two groups of welding torches and the automatic guidance of the adjustable guide rail, the one-time covering welding of all joints on the upper and lower sides of the aluminum alloy door and window can be synchronously completed, avoiding the trouble of welding on the other side.

[0004] Although the above device can complete the welding of aluminum alloy doors and windows, there are still some problems: 1. When welding the splicing joints after splicing aluminum alloy profiles into a rectangular frame, since the diagonals of the splicing joints are set against the hypotenuses and the lengths and widths of different rectangular frames are different, it is impossible to apply diagonal welding to rectangular frames of different specifications during welding. 2. When welding the spliced aluminum alloy profiles, in order to ensure the welding quality, it is necessary to stabilize the diagonals of the aluminum alloy. However, the positions of the diagonals of different specifications of spliced aluminum alloys are different, so it is difficult to fix them during welding. Summary of the Invention

[0005] The purpose of the present invention is to provide a rapid positioning welding device for aluminum profile processing, so as to solve the problems of diagonal welding of splicing frames suitable for aluminum alloy profiles of different specifications and fixing during welding proposed in the above background art.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A rapid positioning welding device for aluminum profile processing, including a base. On both sides of the upper end face of the base, side plates are symmetrically installed. On the side close to each other of the two side plates, a bidirectional telescopic plate is fixedly installed.

[0008] Further, the welding unit includes a moving slot opened on the inner side of the C-shaped frame. An electric push plate is slidably installed in the moving slot through an electric slider. The telescopic end of the electric push plate is fixedly installed with a top frame. The middle part of the top frame is provided with a through setting on both sides. At the cross section of the top frame, a lower frame is fixedly installed. Cleaning rollers are rotatably installed on both sides of the lower frame. An I-shaped plate is slidably installed in the middle of the top frame through an electric slider. A welding torch is fixedly installed in the middle of the lower end face of the I-shaped plate. Vertical rods that penetrate and slide with the I-shaped plate are arranged on both sides of the welding torch. A baffle is jointly installed at the lower end faces of the two vertical rods. The middle part of the baffle is provided with a rectangular through setting, and collecting grooves with a beveled edge are opened on both sides of the upper end face of the baffle.

[0009] Further, a preheating box is fixedly installed on one side of the inner cavity of the lower frame. A recycling box is fixedly installed on the side of the inner cavity of the lower frame away from the preheating box. An air cylinder is fixedly installed on the outside of one side of the lower frame. An outer plate is fixedly installed on the front side of the air cylinder. A shaft rod is rotatably installed in the middle of the outer plate. Belt wheels are fixedly installed on both the shaft rod and one of the cleaning rollers. A belt is jointly installed between the belt wheels. A cam is fixedly installed at the other end of the shaft rod. A control rod is fixedly installed on one side of the cam.

[0010] Further, a compression rod is slidably installed in the middle of the air cylinder. The side of the air cylinder close to the lower frame is communicated with the recycling box through a connecting pipe. A one-way valve is arranged in the recycling box. One side of the compression rod is arranged in a T shape and a rectangular slot is opened in the middle. The control rod slides in the rectangular slot thereof.

[0011] A gas pipe communicating with its inner cavity is fixedly installed at the rear of the air pump, and one end of the gas pipe far away from the air pump is communicated with the preheating box.

[0012] Further, the positioning unit includes ear plates fixedly connected to the outside of the C-shaped frame. A guide rod is slidably installed between the upper and lower ear plates on the same side. A T-shaped part is slidably installed in the middle of the guide rod, and springs are arranged outside the guide rod on both the upper and lower sides of the T-shaped part.

[0013] Further, adjustment grooves are symmetrically opened on the left and right sides of one side of the T-shaped part. A top groove communicating with its interior is opened on the upper end surface of the adjustment groove. An inner rod is fixedly installed in the adjustment groove. An adjustment plate is slidably installed outside the inner rod. Clamping blocks arranged symmetrically are fixedly installed on one side of the left and right adjustment plates. A terminal shaft is fixedly installed on the upper end surface of the adjustment plate. By approaching each other of the two symmetric clamping blocks, it is convenient to position and clamp the diagonal corners of the spliced aluminum profiles for welding.

[0014] Further, a rectangular groove is opened on the upper end surface of the T-shaped part. A rectangular block is slidably installed in the rectangular groove through an electric slider. A folding plate is fixedly installed on the upper end surface of the rectangular block. Symmetrically arranged outer grooves are opened on both sides of the folding plate, and the outer parts of the two terminal shafts are respectively sleeved in the outer grooves on both sides.

[0015] Further, the adjusting plates are arranged in two groups symmetrically up and down. When the two adjusting plates in each group rotate, it is convenient to synchronously weld the upper and lower surfaces of the diagonal corners of different specifications of aluminum profiles spliced into rectangular parts with different lengths and widths.

[0016] Advantages of the present invention: 1. When welding aluminum alloy profiles, the present invention can not only weld two-section aluminum alloy profiles, but also quickly weld between multiple aluminum alloy profiles spliced into rectangular parts with different lengths and widths, thereby improving the working efficiency during welding. And when welding the frames spliced by aluminum alloy profiles with different lengths and widths, the positioning unit flexibly abuts and fixes the profiles, effectively avoiding the situation that the profiles loosen during welding and affecting the welding effect.

[0017] 2. When the present invention welds the aluminum alloy profiles spliced into frames of different lengths and widths, the motor is turned on to drive the gear to rotate. When the gear rotates, it synchronously drives the racks on both sides to slide up and down. When the racks on both sides slide relatively or towards each other, the upper and lower control plates approach or move away from each other at this time. When the two control plates approach each other, the rotation angle between the two adjusting plates becomes larger, thereby increasing the distance between the welding units on both sides. When the two control plates move away from each other, the rotation angle between the two adjusting plates becomes smaller, and the distance between the welding units on both sides is reduced at this time. By adjusting the distance between the welding units on both sides, it can be applied to the welding at the diagonal corners of the frames formed by splicing aluminum alloy profiles of different lengths and widths.

[0018] 3. Through the cleaning of the cleaning roller on the part to be welded soon, the present invention can pre-clean the welding part of the aluminum alloy profile, effectively avoiding the situation that the splicing part to be welded of the aluminum alloy profile affects the welding quality due to impurities. Compared with the existing device, the present invention can pre-clean the welding part while welding the splicing part of the aluminum alloy profile, and at the same time perform continuous linear welding on the splicing part.

[0019] 4. Compared with the existing device, the present invention can preheat the required welding part during the welding of aluminum alloy profiles to improve the welding quality. And through the setting of the recycling box, it can also recycle the heat generated during the welding of aluminum alloy profiles. Through the recycling of heat, on the one hand, it can dissipate the heat of the welding part in time, and on the other hand, it can reuse the recycled heat.

[0020] 5. When fixing the aluminum alloy profile before welding, the electric slider is turned on to drive the rectangular block to slide in the rectangular groove. By the left and right sliding of the rectangular block in the rectangular groove, the folding plate can drive the two end shafts to approach or move away from each other. When the two end shafts approach each other, the two regulating plates slide towards each other on the two inner rods respectively, and at this time the two clamping blocks approach each other to achieve the abutting fixation of the diagonal outside of the splicing part of the aluminum alloy profile.

Specific embodiments

[0023] 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 making creative efforts belong to the protection scope of the present invention.

[0024] As shown in the attached Figures 1-8As shown in the figure, a rapid positioning welding device for aluminum profile processing includes a base 1. On both sides of the upper end face of the base 1, side plates 11 are symmetrically installed. On the side close to each other of the two side plates 11, double-direction telescopic plates 12 are fixedly installed. Connecting plates 13 are installed at the upper and lower telescopic ends of the double-direction telescopic plate 12. A middle frame 14 is jointly installed between the two connecting plates 13 on the same horizontal line. The upper and lower middle frames 14 are arranged symmetrically up and down. On the side far away from each other of the two middle frames 14, gears 20 are rotatably installed through motors. On one side of the gear 20, two adjusting plates 21 which are vertically staggered and coaxially arranged are rotatably installed. On both sides of the adjusting plate 21, round shafts 210 are fixedly installed. An adjusting unit which is slidably connected with the middle frame 14 is arranged above the round shaft 210. At both ends of the adjusting plate 21, U-shaped frames 30 are fixedly installed. Welding units are arranged on the side close to each other of the upper and lower U-shaped frames 30. A positioning unit for fixing the aluminum profile is jointly installed between the upper and lower welding units. In the middle of the upper end face of the base 1, a cross table 10 is fixedly installed. Above the cross table 10, aluminum alloy profiles are spliced into a rectangle.

[0025] Through the telescoping of the double-direction telescopic rod 12, the connecting plates 13 drive the upper and lower middle frames 14 to approach or move away from each other. When the upper and lower middle frames 14 approach each other, the upper welding unit and the lower welding unit approach each other, so as to perform synchronous welding up and down on the connection where the aluminum alloy grooves are spliced into a rectangle. Through the setting of the adjusting unit, the angle between the two vertically staggered adjusting plates 21 can be adjusted. Through the adjustment of the angle between the two adjusting plates 21, it can be applicable to the welding of different-sized rectangular frames spliced by aluminum alloy profiles with different lengths and widths, making the whole device more applicable when welding aluminum alloy profiles. Through the setting of the positioning unit, when the adjusting plate 21 rotates, it always rotates along with the adjusting plate 21, so as to realize the positioning and abutting of the diagonal of the aluminum alloy after splicing, so as to keep the aluminum alloy stable during welding, effectively avoiding the situation that the welded part slides and is unstable during welding. Compared with the existing device, the present invention can not only weld two-section aluminum alloy profiles when welding aluminum alloy profiles, but also can quickly weld between multiple aluminum alloy profiles spliced into rectangular parts with different lengths and widths, thus improving the working efficiency during welding. And when welding the frames spliced by aluminum alloy profiles with different lengths and widths, the positioning unit flexibly abuts and fixes the profiles, effectively avoiding the situation that the profiles loosen during welding and affecting the welding effect.

[0026] As attached Figure 2 、 Figure 3As shown in the figure, the adjusting unit includes a rack 22. The rack 22 is located on both sides of the gear 20 and meshes with the gear 20 respectively. Control plates 23 are fixedly installed at the far ends of the two racks 22 away from each other. The two sides of the control plate 23 are arranged in a V shape. Control grooves 230 are formed at both ends of the control plate 23. The two control grooves 230 are respectively located outside the two circular shafts 210 on both sides and sleeved thereon.

[0027] When welding aluminum alloy profiles spliced into frames of different lengths and widths, the motor is turned on to drive the gear 20 to rotate. When the gear 20 rotates, it synchronously drives the two racks 22 on both sides to slide up and down. When the two racks 22 slide relatively or towards each other, the two control plates 23 move closer to or away from each other. When the two control plates 23 move closer to each other, the rotation angle between the two adjusting plates 31 becomes larger, thereby increasing the distance between the two welding units on both sides. When the two control plates 23 move away from each other, the rotation angle between the two adjusting plates 31 becomes smaller, and at this time, the distance between the two welding units on both sides is reduced. By adjusting the distance between the two welding units on both sides, it can be applied to the welding of the diagonal corners of aluminum alloy profiles spliced into frames of different lengths and widths.

[0028] As shown in the Figure 4 , Figure 6 figure, the welding unit includes a moving groove 31 formed inside the U-shaped frame 30. An electric push plate 32 is slidably installed in the moving groove 31 through an electric slider. The telescopic end of the electric push plate 32 is fixedly installed with a top frame 41. The middle part of the top frame 41 is provided with a through hole on both sides. The cross-section of the top frame 41 is fixedly installed with a lower frame 42. Cleaning rollers 43 are rotatably installed on both sides of the lower frame 42. An I-shaped plate 411 is slidably installed in the middle of the top frame 41 through an electric slider. A welding torch 412 is fixedly installed in the middle of the lower end surface of the I-shaped plate 411. Vertical rods 413 that penetrate and slide through the I-shaped plate 411 are arranged on both sides of the welding torch 412. A baffle plate 414 is jointly installed on the lower end surfaces of the two vertical rods 413. The middle part of the baffle plate 414 is provided with a rectangular through hole, and collecting grooves with a beveled edge are formed on both sides of the upper end surface of the baffle plate 414.

[0029] When welding the diagonal of the frame assembled by aluminum alloy profiles, turn on the electric push plate 32. At this time, the telescopic ends of the upper and lower electric push plates 32 approach each other, so that the upper and lower top frames 41 move towards the frame assembled by aluminum alloy profiles. Until the cleaning roller 43 contacts the rectangular frame assembled by aluminum alloy, at this time, the middle of the baffle 414 is on the same horizontal line as the weld. Then turn on the welding torch 412, and the welding torch 412 welds the weld at the joint of the aluminum alloy profiles through the baffle 414. Drive the electric push plate 32 to move in the moving groove 31 by turning on the electric slider. At this time, the top frame 41 and the lower frame 42 drive the welding torch 412 to continuously move and weld the joint. And when the lower frame 42 moves, the cleaning roller 43 can contact the joint of the aluminum alloy first. When the lower frame 42 moves, the cleaning roller 43 rolls on the joint to be welded, so as to clean the place to be welded. Through the cleaning of the cleaning roller 43 on the joint to be welded, the joint to be welded of the aluminum alloy profile can be pre-cleaned, effectively avoiding the situation that the joint to be welded of the aluminum alloy profile is affected by impurities and affects the welding quality. Compared with the existing device, the present invention can pre-clean the welding joint when welding the joint of the aluminum alloy profile, and at the same time perform continuous linear welding on the joint.

[0030] As shown in the Figure 7 accompanying drawings, a preheating box 44 is fixedly installed on one side of the inner cavity of the lower frame 42, a recycling box 45 is fixedly installed on the side of the inner cavity of the lower frame 42 away from the preheating box 44, an air cylinder 46 is fixedly installed on the outer side of the lower frame 42, an outer plate is fixedly installed on the front side of the air cylinder 46, a shaft rod is rotatably installed in the middle of the outer plate, belt wheels are fixedly installed on the shaft rod and one of the cleaning rollers 43, a belt is commonly installed between the belt wheels, a cam 462 is fixedly installed at the other end of the shaft rod, and a control rod is fixedly installed on one side of the cam 462.

[0031] When the preheating box 44 is turned on, it can preheat the splicing part to be welded through the preheating box 44 when the welding torch 412 welds the welding part. By preheating the aluminum alloy splicing part in advance, the welding quality of the aluminum alloy profile can be effectively improved. And when the lower frame 42 moves to drive the cleaning roller 43 to rotate to pre-clean the splicing part, the rotation of the cleaning roller 43 can also drive the shaft rod on the outer plate to rotate through the setting of the belt pulley and the belt. When the shaft rod rotates, it synchronously drives the cam 462 to rotate. When the cam 462 rotates, it drives the compression rod 461 to be compressed in the air cylinder 46 through the control rod, so that the recovery box 45 recovers the high heat generated during the welding of the welding torch 412. The heat recovered during welding is transmitted into the lower frame 42 through the air transmission pipe 463. Compared with the existing device, the present invention can preheat the required welding part during the welding of the aluminum alloy profile to improve the welding quality, and through the setting of the recovery box 45, it can also recover the heat generated during the welding of the aluminum alloy profile. Through the recovery of the heat, on the one hand, it can dissipate the heat of the welding part in time, and on the other hand, it can reuse the recovered heat.

[0032] As shown in the Figure 6 accompanying drawings, a compression rod 461 is slidably installed in the middle of the air cylinder 46. One side of the air cylinder 46 close to the lower frame 42 is communicated with the recovery box 45 through a connecting pipe. A one-way valve is arranged in the recovery box 45. One side of the compression rod 461 is arranged in a T shape and a rectangular groove is opened in the middle. The control rod is slidably located in the rectangular groove thereof.

[0033] A gas transmission pipe 463 communicating with its inner cavity is fixedly installed at the rear of the air cylinder 46. One end of the gas transmission pipe 463 away from the air cylinder 46 is communicated with the preheating box 44.

[0034] As shown in the Figure 4 and Figure 5 accompanying drawings, the positioning unit includes an ear plate 33 fixedly connected to the outside of the U-shaped frame 30. A guide rod 34 is slidably installed between the upper and lower two ear plates 33 on the same side. A T-shaped part 35 is slidably installed in the middle of the guide rod 34. Springs are arranged on both the upper and lower sides of the T-shaped part 35 outside the guide rod 34.

[0035] Regulating grooves 351 are symmetrically opened on one side of the T-shaped part 35. A top groove 352 communicating with its internal is opened on the upper end surface of the regulating groove 351. An inner rod 353 is fixedly installed in the regulating groove 351. A regulating plate 354 is slidably installed outside the inner rod 353. Clamping blocks 355 arranged symmetrically are fixedly installed on one side of the left and right two regulating plates 354. An end shaft 356 is fixedly installed on the upper end surface of the regulating plate 354. The diagonal corners of the spliced aluminum profile can be clamped and fixed for welding by the mutual approach of the two symmetric clamping blocks 355.

[0036] When fixing the aluminum alloy profile before welding, the electric slider is turned on to drive the rectangular block 358 to slide in the rectangular groove 357. By sliding the rectangular block 358 left and right in the rectangular groove 357, the folding plate 359 can drive the two end shafts 356 to approach or move away from each other. When the two end shafts 356 approach each other, the two regulating plates 354 slide towards each other on the two inner rods 353 respectively. At this time, the two clamping blocks 355 approach each other to achieve abutting fixation on the diagonal outside of the splicing joint of the aluminum alloy profile.

[0037] A rectangular groove 357 is formed on the upper end surface of the T-shaped part 35. A rectangular block 358 is slidably installed in the rectangular groove 357 through an electric slider. A folding plate 359 is fixedly installed on the upper end surface of the rectangular block 358. Symmetrically arranged outer grooves 3590 are formed on both sides of the folding plate 359, and the outer parts of the two end shafts 356 are sleeved in the outer grooves 3590 on both sides respectively.

[0038] As shown in the Figure 3 attachment, there are two sets of symmetrically arranged adjusting plates 21, which are arranged up and down. When each group of two adjusting plates 21 rotate, they can synchronously weld the upper and lower surfaces of the diagonals of different specifications of aluminum profiles spliced into rectangular parts with different lengths and widths.

[0039] In use, the bidirectional telescopic rod 12 expands and contracts, so that the connecting plate 13 drives the upper and lower middle frames 14 to approach or move away from each other. When the upper and lower middle frames 14 approach each other, the upper welding unit and the lower welding unit approach each other, so as to synchronously weld the upper and lower joints of the aluminum alloy profile spliced into a rectangle. Through the setting of the adjusting unit, the angle between the two adjusting plates 21 arranged up and down and staggered can be adjusted. By adjusting the angle between the two adjusting plates 21, it can be applied to the welding of rectangular frames spliced by aluminum alloy profiles with different lengths and widths. When the whole device welds the aluminum alloy profile, the applicability is more extensive. Through the setting of the positioning unit, when the adjusting plate 21 rotates, it can always rotate following the adjusting plate 21, so as to realize the positioning abutment at the diagonal of the spliced aluminum alloy, so as to keep the aluminum alloy stable during welding, effectively avoiding the situation of sliding and instability at the welding joint during welding. Compared with the existing device, when welding the aluminum alloy profile, the present invention can not only weld the two-section aluminum alloy profile, but also quickly weld between multiple aluminum alloy profiles spliced into rectangular parts with different lengths and widths, thus improving the working efficiency during welding. And when welding the frame spliced by aluminum alloy profiles with different lengths and widths, the positioning unit flexibly abuts and fixes the profiles, effectively avoiding the situation that the profiles loosen during welding and affecting the welding effect. When welding the aluminum alloy profiles spliced into frames with different lengths and widths, the motor is turned on to drive the gear 20 to rotate. When the gear 20 rotates, it synchronously drives the racks 22 on both sides to slide up and down. When the racks 22 on both sides slide relatively or towards each other, the upper and lower control plates 23 approach or move away from each other. When the two control plates 23 approach each other, the rotation angle between the two adjusting plates 31 becomes larger, thereby increasing the distance between the welding units on both sides. When the two control plates 23 move away from each other, the rotation angle between the two adjusting plates 31 becomes smaller, and at this time, the distance between the welding units on both sides is reduced. By adjusting the distance between the welding units on both sides, it can be applied to the welding at the diagonal corners of the frames spliced by aluminum alloy profiles. When welding the diagonal corners of the frames spliced by aluminum alloy profiles, the electric push plate 32 is turned on. At this time, the telescopic ends of the upper and lower electric push plates 32 approach each other, so that the upper and lower top frames 41 move towards the frame spliced by aluminum alloy profiles. Until the cleaning roller 43 contacts the rectangular frame spliced by aluminum alloy, at this time, the middle of the baffle 414 is on the same horizontal line as the weld. Then the welding torch 412 is turned on, and the welding torch 412 welds the weld at the splicing part of the aluminum alloy profiles through the baffle 414. The electric slider is turned on to drive the electric push plate 32 to move in the moving groove 31. At this time, the top frame 41 and the lower frame 42 drive the welding torch 412 to perform continuous moving welding on the splicing part. And when the lower frame 42 moves, the cleaning roller 43 can contact the splicing part of the aluminum alloy first. When the lower frame 42 moves, the cleaning roller 43 rolls on the splicing part to be welded, so as to clean the place to be welded. By cleaning the place to be welded by the cleaning roller 43, the splicing part of the aluminum alloy profiles to be welded can be pre-cleaned, effectively avoiding the situation that the splicing part of the aluminum alloy profiles to be welded is affected by impurities and affects the welding quality. Compared with the existing device, the present invention can pre-clean the welding part and perform continuous linear welding on the splicing part when welding the splicing part of the aluminum alloy profiles; When the preheating box 44 is turned on, the preheating box 44 can preheat the splicing joint to be welded when the welding torch 412 welds the welding joint. By preheating the aluminum alloy splicing joint in advance, the welding quality of the aluminum alloy profile can be effectively improved. When the lower frame 42 moves to drive the cleaning roller 43 to rotate to pre-clean the splicing joint, the rotation of the cleaning roller 43 can also drive the shaft rod on the outer plate to rotate through the setting of the pulley and the belt. When the shaft rod rotates, the cam 462 rotates synchronously. When the cam 462 rotates, the compression rod 461 is driven by the control rod to be compressed in the air cylinder 46, so that the recovery box 45 recovers the high heat generated during the welding of the welding torch 412. The heat recovered during welding is transmitted into the lower frame 42 through the air transmission pipe 463. Compared with the existing device, the present invention can preheat the required welding joint during the welding of the aluminum alloy profile to improve the welding quality. And through the setting of the recovery box 45, the high temperature generated during the welding of the aluminum alloy profile can also be recovered. Through the recovery of the heat, on the one hand, the welding joint can be timely dissipated, and on the other hand, the recovered heat can be reused. When fixing the aluminum alloy profile before welding, the electric slider is turned on to drive the rectangular block 358 to slide in the rectangular groove 357. By the left and right sliding of the rectangular block 358 in the rectangular groove 357, the folding plate 359 can drive the two end shafts 356 to approach or move away from each other. When the two end shafts 356 approach each other, the two regulating plates 354 slide closer to each other on the two inner rods 353 respectively.
