Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of tailor-made welding machines, and in particular, to a laser welding machine for tailor-made welding of automobile panels. Background Art

[0002] The welding of automobile panels is to splice thin plates of different materials, thicknesses or coatings together through laser welding technology to form high-performance automobile parts, so as to reduce the number of parts and the weight of the vehicle body and improve material utilization. The technology of panel welding is widely used in the automotive industry and is widely used in the manufacture of vehicle body structural parts. When welding automobile panels, laser welding machines are generally used.

[0003] In the prior art, when welding two or more automobile panels of the same or different materials, the rust and oil stains on the edges of the joints of the panels to be welded are first removed, and then the reference ends of the panels are aligned. Then, according to different welding methods and process requirements, the gap between the panels is determined, and then welding is performed. Before welding, the welding machine should be aligned with the welding seam and pre-moved once. The machine head should be used to check whether the center line of the weld and the moving track of the welding machine coincide. After confirming that they are correct, welding can be performed.

[0004] Since automobile plates will shift during the transportation process, the width of the gap at the docking position of the two plates will be different. If it is not adjusted in time, it will affect the welding quality, making it more difficult to adjust and correct the two plates. In particular, when there needs to be an angle between the two plates, if the angle of the two plates is adjusted first, it will be difficult to adjust the docking position. If the docking position is adjusted first to dock the two plates together, a gap will appear at the docking position of the two plates when the angle is adjusted, thereby affecting the progress of welding and reducing the efficiency of steel plate welding.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figures 1 to 7As shown, it shows a laser welding machine for welding automobile plates in one embodiment of the present invention, including an equipment frame 1, a welding frame 2 is fixedly installed on the equipment frame 1, a laser welding device 3 is installed on the welding frame 2, and also includes a supporting frame 4, a first driving member 8, a sliding frame 5, a mounting frame 6, a sliding frame 7, a shifting assembly, an alignment assembly and an angle adjustment assembly. The supporting frame 4 is slidably installed on the equipment frame 1, and two first driving members 8 are symmetrically and fixedly installed inside the equipment frame 1. The output ends of the two first driving members 8 are fixedly connected to the supporting frame 4. Two sliding frames 5 are symmetrically and slidably installed on the supporting frame 4. The tops of the two sliding frames 5 are both provided with mounting frames 6. The two mounting frames 6 are symmetrically arranged, and the two mounting frames 6 are both slidably installed. A sliding frame 7 is installed, and a shifting assembly is installed on the carrying frame 4 for simultaneously adjusting the relative positions of the two sliding frames 5 and the carrying frame 4. The shifting assembly includes a partition 9, a driving gear 10, a rack 11 and a drive motor 12. The partition 9 is fixedly mounted inside the carrying frame 4, and the partition 9 slides with the sliding frame 5. A cavity is provided between the partition 9 and the inner top wall of the carrying frame 4, and the driving gear 10 is rotatably installed inside the cavity. A rack 11 is fixedly mounted on one end of the two sliding frames 5 close to the driving gear 10, and the two racks 11 are engaged with the driving gear 10. The two racks 11 are arranged in parallel, and the drive motor 12 is fixedly mounted on the partition 9. A transmission member 13 for transmitting power is provided between the output end of the drive motor 12 and the driving gear 10.

[0025] It should be added that the transmission component 13 is composed of a worm gear, which is rotatably installed at the bottom of the partition 9, and the worm gear is coaxial with the driving gear 10 and fixedly connected. The worm is also rotatably installed at the bottom of the partition 9, and the worm is engaged with the worm gear. One end of the worm is coaxially and fixedly connected to the output end of the drive motor 12.

[0026] Specifically, when welding two locomotive plates, first place the two plates on the two sliding racks 7 respectively. At this time, the edges of the two plates that need to be welded together are close to the center position of the carrying frame 4. At this time, start the setting of the alignment component, first adjust the position of the side of the two plates to be welded, so that the positions of the two plates to be welded remain parallel, and then fix the two plates on the two sliding racks 7 respectively, and then align the two plates. At this time, turn on the drive motor 12, and the drive motor 12 drives the worm gear to rotate through the worm, and the worm gear drives the driving gear 10 to rotate, and the driving gear 10 can simultaneously drive the two racks 11 to rotate in reverse When the two plates are welded, the angle between them can be adjusted by adjusting the angle of the two plates. When the two plates are welded, the angle between them can be adjusted by adjusting the angle of the two plates. However, it is necessary to ensure that the surfaces of the two plates welded together after the angle is adjusted remain tightly connected. Then, the two plates are sent to the welding area and the welded positions of the two plates are welded.

[0027] The first driving member 8 is turned on, and the first driving member 8 drives the carrying frame 4 to move, thereby moving the two plates into the welding frame 2, and then the laser welding device 3 is turned on. The laser welding device 3 consists of a positioning system and a welding device, such as Figure 3 As shown, the positioning system can realize movement in three directions of X-axis, Y-axis and Z-axis, which is convenient for adjusting the welding position of the laser welding device 3. The two plates can be welded by the laser welding device 3, and then the first driving member 8 is retracted until the two welded plates are moved out of the welding frame 2 through the supporting frame 4, and then the alignment component is loosened, the welded automobile plate is taken out, and then the two plates to be welded are placed on the two sliding frames 7 respectively, and the above steps are repeated to weld them.

[0028] like Figures 1 to 4 As shown, the two sliding frames 7 are each equipped with an alignment component for docking the ends of the automobile plates on the two mounting frames 6 that need to be welded together. The alignment component includes a through slot 14, a second driving member 15, a docking portion and a gear portion. The two sliding frames 7 are each provided with a through slot 14 at one end away from the center position of the supporting frame 4. Two second driving members 15 are symmetrically and fixedly installed on one side of each mounting frame 6 away from the center position of the supporting frame 4. The output end of the second driving member 15 is fixedly connected to the sliding frame 7. A docking portion is provided on the two sliding frames 7 for adjusting the position of the automobile plate and fixing the automobile plate. The gear portion is installed on the supporting frame 4 and is located between the two mounting frames 6 for cooperating with the docking portion to adjust the position of the automobile plate.

[0029] Specifically, when placing two plates that need to be welded on two sliding racks 7 respectively, first adjust the positions where the two plates need to be welded together through the settings of the docking part and the gear part, so that the sides that need to be welded together are relatively parallel, and then retract the gear part, and fix the two plates on the corresponding sliding racks 7 through the setting of the docking part, and then turn on the second driving member 15, and the second driving member 15 pushes the sliding rack 7 to move until the sides of the two plates that need to be welded are docked together.

[0030] The above, such as Figure 4 、 Figure 7 As shown, the docking part includes a slide groove 16, a primary clamping block 17, a third driving member 18, a secondary clamping block 19 and a fourth driving member 20. Each sliding frame 7 is provided with a plurality of slide grooves 16 in parallel. The slide grooves 16 and the through grooves 14 are arranged perpendicular to each other. Two primary clamping blocks 17 are symmetrically and slidably provided on each slide groove 16. A plurality of third driving members 18 are provided at equal distances on both sides of the two sliding frames 7. The plurality of third driving members 18 correspond one-to-one to the plurality of primary clamping blocks 17. The output end of the third driving member 18 is fixedly connected to the primary clamping block 17. The two sliding frames 7 are provided with a secondary clamping block 19 at one end away from the center position of the carrying frame 4. The fourth driving member 20 is fixedly installed on the two mounting frames 6. The two fourth driving members 20 correspond one-to-one to the two secondary clamping blocks 19 and are fixedly connected.

[0031] Specifically, when the two plates that need to be welded are placed on the two sliding frames 7 respectively, the gear part is in the working position. At this time, the fourth driving member 20 is turned on, and the fourth driving member 20 pushes the automobile plate to move through the secondary clamping block 19. Since the welding position of the plate is close to the center position of the supporting frame 4, that is, when the fourth driving member 20 pushes the plate to move through the secondary clamping block 19, the side of the plate that needs to be welded contacts the gear part, so that under the action of the gear part, the sides of the two plates that need to be welded together are arranged relatively parallel, and then the third driving member 18 is turned on to push the primary clamping block 17 to move until the plate is fixed by the setting of the primary clamping block 17, and then the gear part is retracted, and the two plates are connected together.

[0032] It should be added that, by providing the slide groove 16 , the bottom edge of the first-level clamping block 17 is prevented from contacting the plate, thereby reducing the occurrence of unstable clamping.

[0033] The above, such as Figure 4 As shown, the shifting portion includes a baffle 21 and a fifth driving member 22 . The baffle 21 is arranged between the two mounting frames 6 . The fifth driving member 22 is fixedly installed inside the supporting frame 4 . The output end of the fifth driving member 22 is fixedly connected to the baffle 21 .

[0034] Specifically, after the welding surfaces of the two plates come into contact with the baffle 21, the fifth driving member 22 can be retracted after fixing the relative positions of the two plates and the corresponding sliding frames 7. The fifth driving member 22 drives the baffle 21 to move until the baffle 21 moves away from the position in contact with the plates.

[0035] like Figure 7 As shown, both sliding frames 5 are equipped with an angle adjustment assembly for adjusting the angle of the mounting frame 6. The angle adjustment assembly includes an outer arc frame 23, an inner arc frame 24 and a sixth driving member 25. The outer arc frame 23 is fixedly mounted on both sliding frames 5. The two outer arc frames 23 are symmetrically arranged. The outer arc frame 23 and the inner arc frame 24 are slidably matched. The center positions of the two outer arc frames 23 coincide. The sixth driving member 25 is rotatably installed inside the two outer arc frames 23. The sixth driving member 25 is rotatably connected to the inner top wall of the inner arc frame 24.

[0036] Among them, when the thickness difference between the two plates is too large, in order to avoid over-melting of the thin plate or under-melting of the thick plate, the angle of the plates is generally adjusted, for example, adjusting the angle of the thin plate away from the laser side to improve the welding quality.

[0037] Specifically, when the angle of the two plates needs to be adjusted, the corresponding sixth driving member 25 is turned on, and the sixth driving member 25 drives the inner arc frame 24 to move in the outer arc frame 23, thereby driving the mounting frame 6 at the corresponding position to move along the direction of the outer arc frame 23, thereby adjusting the angle of the automobile plate.

[0038] It should be supplemented that the first driving member 8 , the second driving member 15 , the third driving member 18 , the fourth driving member 20 , the fifth driving member 22 and the sixth driving member 25 are preferably in the form of electric cylinders.

[0039] The working principle or usage process of this application is as follows: When welding two locomotive plates, first place the two plates on the two sliding frames 7 respectively. The edges of the two plates that need to be welded together are close to the center of the supporting frame 4. At the same time, the baffle 21 is in the working position. At this time, the fourth driving member 20 is turned on. The fourth driving member 20 pushes the automobile plate to move through the secondary clamping block 19. Since the welding position of the plate is close to the center of the supporting frame 4, that is, when the fourth driving member 20 pushes the plate to move through the secondary clamping block 19, the side of the plate that needs to be welded contacts the baffle 21, so that under the action of the baffle 21, the sides of the two plates that need to be welded together are arranged relatively parallel, and then the two plates need to be fixed.

[0040] When the two plates are fixed on the corresponding sliding frame 7 respectively, the third driving member 18 is turned on to push the first clamping block 17 to move until the plate is fixed by the setting of the first clamping block 17, and then the fifth driving member 22 is retracted. The fifth driving member 22 drives the baffle 21 to move until the baffle 21 moves away from the position in contact with the plate. At this time, the two plates that need to be welded together are arranged in a relatively parallel manner, but they do not correspond to each other. The two plates need to be aligned. At this time, the driving motor 12 is turned on. The driving motor 12 drives the worm gear to rotate through the worm, and the worm gear drives the driving gear 10 to rotate. The driving gear 10 can simultaneously drive the two racks 11 to move in the opposite direction. At this time, the two sliding frames 5 can be driven to move in the opposite direction on the carrying frame 4 through the setting of the rack 11, thereby driving the mounting frame 6 to move through the setting of the inner arc frame 24 and the outer arc frame 23 until the welding positions of the two plates are aligned, and then the second driving member 15 is turned on. The second driving member 15 drives the sliding frame 7 to move until the two plates need to be welded. The side is butt-jointed.

[0041] If a certain angle needs to be created between the two plates, for example, when the thickness difference between the two plates is too large, in order to avoid over-melting of the thin plate or under-melting of the thick plate, the angle of the plate is generally adjusted, for example, the angle of the thin plate is adjusted in the direction away from the laser side. At this time, the corresponding sixth driving member 25 is turned on, and the sixth driving member 25 drives the inner arc frame 24 to move in the outer arc frame 23, thereby driving the mounting frame 6 at the corresponding position to move along the direction of the outer arc frame 23, thereby adjusting the angle of the automobile plate. However, it is necessary to ensure that the surfaces of the two plates butted together after the angle is adjusted remain tightly butted before welding them together.

[0042] At this time, the first driving member 8 is turned on, and the first driving member 8 drives the carrying frame 4 to move, thereby moving the two plates into the welding frame 2, and then the laser welding device 3 is turned on. The laser welding device 3 consists of a positioning system and a welding device, such as Figure 3 As shown, the positioning system can realize movement in three directions of X-axis, Y-axis and Z-axis, which is convenient for adjusting the welding position of the laser welding device 3. The two plates can be welded by the laser welding device 3, and then the first driving member 8 is retracted until the two welded plates are moved out of the welding frame 2 through the supporting frame 4, and then the third driving member 18 is released to take out the welded automobile plate, and then the two plates to be welded are placed on the two sliding frames 7 respectively, and the above steps are repeated to weld them.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
