Description

Technical Field

[0001] The present application relates to the field of welding equipment, and in particular to a laser welding device with a flipping mechanism. Background Art

[0002] Welding tooling is used in manufacturing fields such as aviation, construction, and automobile production. Excellent welding tooling equipment can greatly improve the welding processing technology level and product quality, improve production efficiency, reduce production costs, and bring significant advantages to mechanical production and processing.

[0003] In the related technology, the workpiece needs to be turned over during the specific welding process to weld the welding position on the back. The traditional turning mechanism only has the function of turning over, and the workpiece needs to be cooled and the welding slag removed after welding. This makes it impossible to carry out the welding, cooling and subsequent slag removal steps in the workpiece processing process simultaneously, which will affect the overall processing efficiency of the workpiece and is not conducive to the daily processing and production of the workpiece. Summary of the invention

[0004] The present application provides a laser welding device with a flipping mechanism, the purpose of which is to optimize the welding, cooling and subsequent slag removal steps in the workpiece processing process, so that the welding, cooling and slag removal steps can be carried out simultaneously during the processing process, thereby helping to improve the overall processing efficiency of the workpiece and facilitating the daily processing and production of the workpiece.

[0005] The present application provides a laser welding device with a flipping mechanism, which adopts the following technical solution: A laser welding device with a flipping mechanism comprises an operating table, a sliding mechanism is provided on one side of the operating table, the sliding mechanism comprises a first sliding seat, a second sliding seat and a third sliding seat, the first sliding seat and the second sliding seat slide on a horizontal plane along the X and Y directions respectively, the third sliding seat slides in a vertical direction along the Z direction, and a welding gun is installed on the third sliding seat; The operating table is provided with a flipping mechanism, which is used to flip the welding tooling; the flipping mechanism is provided with a first plate body and a second plate body, the first plate body and the second plate body are both slidably arranged in a direction close to or away from the tooling, and the first plate body and the second plate body are both provided with a cooling surface and a slag removal surface, and the cooling surface and the slag removal surface are used to cool and remove slag from the tooling after the tooling welding is completed; The flipping mechanism is provided with a driving mechanism, the driving mechanism is connected to the first plate body and the second plate body, and the driving mechanism is used to drive the first plate body and the second plate body to slide towards or away from the tooling.

[0006] By adopting the above technical solution, in this setting mode, after the top surface welding of the tooling is completed, the tooling is flipped 180° through the flipping mechanism so that the bottom surface of the tooling faces upward, thereby facilitating the welding of the bottom surface of the tooling. At the same time, after the top surface welding is completed, it is flipped downward, and the top surface is cooled and deslaged by the first plate body and the second plate body at this time, so that during the welding process of the bottom surface of the tooling, the top surface of the tooling is cooled and deslaged synchronously. After the bottom surface welding is completed, the bottom surface is cooled and deslaged by the first plate body and the second plate body.

[0007] The purpose of doing so is to shorten the processing time of the tooling as a whole. Compared with the processing method of traditional tooling, it is necessary to wait until the top and bottom surfaces are fully welded before cooling and slag removal. In the embodiment of the present application, after the welding of the top surface of the tooling is completed, it is not necessary to wait for the welding of the bottom surface to be completed before cooling and slag removal can be directly carried out, so that the cooling and slag removal of the top surface can be carried out simultaneously with the welding of the bottom surface, thereby effectively avoiding the occurrence of processing intervals during the tooling processing, and there is no need to wait until the welding of the bottom surface is completed before cooling, slag removal and other processes. The welding, cooling and subsequent slag removal steps in the workpiece processing process are optimized by using a flip mechanism and a first plate body and a second plate body provided on the flip mechanism, so that the welding, cooling and slag removal steps can be carried out simultaneously during the processing process, thereby helping to improve the overall processing efficiency of the workpiece and facilitating the daily processing and production of the workpiece.

[0008] Preferably, the flipping mechanism includes a lifting slide rail, a lifting plate, a lifting seat, a rotating shaft, a first rotating seat, a second rotating seat and a moving seat, the lifting slide rail is vertically arranged, the lifting slide rail is provided with a first sliding groove along its length direction, the lifting plate is slidably installed in the first sliding groove, the lifting seat is integrally connected with one side of the lifting plate, the rotating shaft is inserted into the lifting seat in the horizontal direction, and the two ends of the rotating shaft respectively extend out of the two sides of the lifting seat, the first rotating seat and the second rotating seat are respectively rotatably connected to the two ends of the rotating shaft, the moving seat is vertically arranged, a horizontal slide rail is installed on one side of the lifting slide rail in the horizontal direction, the moving seat is slidably installed on the horizontal slide rail, the moving seat is used to drive the first rotating seat to rotate, and the rotating shaft drives the tooling to flip while rotating.

[0009] By adopting the above technical solution, the initial state of the tooling welding is that the lifting seat is located at the bottom of the lifting slide rail. At this time, the tooling is connected to the rotating shaft on the lifting seat through the fastening seat, and two positioning seats for clamping and positioning the tooling are installed on the operating table. The tooling is clamped and positioned by the corresponding two positioning seats, and the welding torch welds the top surface of the tooling. After the top surface welding is completed, the two positioning seats move away from each other. At this time, the lifting plate rises under the drive of the cylinder and synchronously drives the lifting seat to rise. As the lifting seat rises, when the first rotating seat rises to the top of the moving seat, the moving seat drives the first rotating seat to rotate. While the first rotating seat rotates, it synchronously drives the rotating shaft and the second rotating seat to rotate. While the rotating shaft rotates, it drives the tooling to flip.

[0010] The first rotating seat rotates under the drive of the moving seat, thereby driving the rotating shaft to rotate through the first rotating seat, and then driving the tooling and the second rotating seat to flip through the rotating shaft.

[0011] Preferably, the first rotating seat includes an upper rotating member and a lower rotating member. The upper rotating member and the lower rotating member are distributed one above the other. Both the upper rotating member and the lower rotating member are composed of a rotating plate and a rotating rod integrally connected. Both rotating plates are integrally connected to the rotating shaft, and the included angle between the two rotating plates is 120°. The moving seat is composed of a moving plate, a left pressing plate, and a right pressing plate. The moving plate is integrally in a "U" - shaped structure. The left pressing plate and the right pressing plate are integrally formed on the left and right sides of the top of the moving plate along the horizontal direction. The left pressing plate and the right pressing plate are used to drive the upper rotating member and the lower rotating member to rotate, and while the upper rotating member and the lower rotating member rotate, they synchronously drive the rotating shaft to rotate.

[0012] By adopting the above technical solution, specifically, as the lifting seat rises, when the first rotating seat rises to the top of the moving seat, in this state, the rotating rod of the upper rotating member is located below the right pressing plate. As the lifting seat continues to rise, when the rotating rod of the upper rotating member abuts against the bottom of the right pressing plate, since the height of the right pressing plate is fixed, after the rotating rod abuts against the bottom of the pressing plate, the rotating rod cannot continue to rise with the lifting seat. At this time, the rotating rod starts to rotate as the pressing plate presses down, and drives the rotating plate to rotate, and then drives the tooling to flip through the rotating shaft. As the rotating shaft rotates, the positions of the upper rotating member and the lower rotating member are exchanged during the rotation process: the upper rotating member rotates to the lower position, and the lower rotating member rotates to the upper position.

[0013] After the tooling is flipped, the lifting seat descends until the tooling is clamped and positioned by the corresponding positioning seat and welding of the bottom surface begins. During this process, when the upper rotating member that has rotated to the bottom moves down to the bottom, the upper rotating member drives the moving seat to slide in the horizontal direction. Here, the purpose of the sliding of the moving seat is because, after the upper rotating member and the lower rotating member exchange positions, the position between the left pressure plate of the lower rotating member that rotates to the top is misaligned, that is, the lower rotating member is not directly below the left pressure plate at this time. This will result in that when the lifting seat rises again and the lower rotating member rises to the left pressure plate, the rotating rod of the lower rotating member is not directly below the left pressure plate, which means that the left pressure plate cannot press down the rotating rod of the lower rotating member, and the tooling cannot be flipped.

[0014] The purpose of sliding the moving seat is to move the rotating rod of the lower rotating member to just below the left pressure plate, so that when the lifting seat rises again, the left pressure plate can press down the rotating rod on the lower rotating member to start the next flip.

[0015] Preferably, a driving member is integrally formed at the middle end of the bottom of the movable plate, and the driving member is in a triangular structure as a whole, and its left and right sides are wedge-shaped surfaces. The driving member cooperates with the rotating rod in a wedge shape to drive the movable plate to slide.

[0016] By adopting the above technical solution, when the moving plate is driven to slide, the rotating rod on the upper rotating member that rotates to the bottom corresponds to the left wedge surface of the driving member. As the lifting seat moves downward, when the rotating rod on the upper rotating member abuts against the left wedge surface of the driving member, the rotating rod will squeeze the left wedge surface of the driving member during the gradual downward movement, thereby driving the driving member to slide to the right, and then driving the moving plate to slide to the right through the driving member. When the moving plate slides to the right, it can drive the left pressure plate to move right to just above the rotating rod of the lower rotating member. When the lifting seat rises again, the left pressure plate can press down the rotating rod of the lower rotating member, thereby starting the flipping of the next side.

[0017] Preferably, the driving mechanism includes a first driving block, a second driving block, an adapter plate, a adapter rod and a mounting plate, the first driving block is vertically arranged, the second driving block is located below the first driving block, the ends of the first driving block and the second driving block that are close to each other are both wedge-shaped, and the wedges of the two are matched, the side wall of the first driving block is integrally connected to the end of the lifting plate, the adapter plate is integrally installed on the bottom of the second driving block, the adapter rod is integrally connected to the adapter plate, the adapter rod is an "L"-shaped structure as a whole, one end of the adapter rod is integrally connected to the bottom of the adapter plate, and the other end of the adapter rod is fixed with a mounting box, and the first plate body and the second plate body are both arranged in the mounting box.

[0018] By adopting the above technical solution, specifically when driving the first plate body and the second plate body, the lifting plate drives the first driving block to lift and lower during the lifting process, thereby driving the second driving block to slide through the first driving block, and during the sliding process, the second driving block drives the installation box to slide toward or away from the tooling through the adapter plate and the adapter rod, thereby driving the first plate body and the second plate body to cool and remove slag from the tooling.

[0019] Preferably, a second arc-shaped slide groove is formed on the side wall of the mounting plate, and a slider sliding in the second slide groove is fixed to the side wall of the second driving block, and the slider drives the second driving block to slide during the sliding process in the second slide groove.

[0020] The purpose of adopting the above technical solution is that when the tooling is cooling and removing slag, the installation box needs to slide from one side of the tooling to the other side of the tooling. Since the tooling needs to be lifted and lowered when flipping, the movement trajectory of the installation box needs to be able to slide while maintaining the lifting, which requires the movement trajectory of the installation box to be arc-shaped. The arc-shaped second slide groove and the slider sliding in the second slide groove are used to realize the movement trajectory of the second driving block to be arc-shaped, and the movement trajectory of the installation box is arc-shaped through the adapter plate and the adapter rod.

[0021] Preferably, the cooling surface and the slag removing surface are both rotatably mounted on the first plate body and the second plate body, and the cooling surface and the slag removing surface on the first plate body and the second plate body are staggered.

[0022] By adopting the above technical solution, when the welding of the top surface of the tooling is completed, the lifting seat rises, so that the tooling is turned over. The installation box drives the first plate body and the second plate body to rise while sliding toward the other side of the tooling. When the tooling is turned over, the welded top surface faces down, and the unwelded bottom surface faces up. At this time, the cooling surface of the first plate body faces up, and the slag removal surface of the second plate body faces up. After the tooling is turned over, it starts to descend. During this process, the installation box drives the first plate body and the second plate body to descend synchronously, and drives the first plate body and the second plate body to slide. During the sliding process of the first plate body and the second plate body, the first plate body cools the top surface during the sliding process, and the second plate body closely follows the first plate body. After the cooling surface on the first plate body cools the top surface, the slag removal surface on the second plate body that follows the first plate body removes slag from the cooled part of the top surface.

[0023] The purpose of doing so is that it is more appropriate to remove the slag when the weld is cooled to a certain temperature. If the weld temperature is too high, the slag removal may affect the structure and properties of the weld metal, and may even cause cracks, which in turn may affect the welding quality of the tooling. In the embodiment of the present application, after the cooling surface on the first plate cools the top surface, the slag removal plate on the second plate removes the slag from the portion where the top surface has been cooled, thereby effectively ensuring the welding quality of the tooling.

[0024] After the top surface welding is completed, during the process of flipping and descending, the first plate body and the second plate body slide from one side of the tooling to the other side of the tooling. During this sliding process, the cooling surface on the first plate body first cools the top surface, and then the slag removal surface on the second plate body removes slag from the part where the top surface cooling is completed.

[0025] The purpose of setting the cooling surface and slag removal surface on the first plate body and the second plate body as a rotating installation method is because: after the bottom surface welding is completed, the lifting seat rises. During this rising process, the top surface is cooled and slag removed twice by the first plate body and the second plate body. However, since the first cooling and slag removal of the top surface is performed with the first plate body in front and the second plate body in the back, when the bottom surface welding is completed, the lifting seat rises. At this time, when the installation box rises, the first plate body is in the back and the second plate body is in the front. If this is the case, the slag removal surface on the second plate body is first deslagging, and then the cooling surface on the first plate body is cooled. This does not conform to the process of cooling the tooling first and then deslagging.

[0026] Therefore, the cooling surface and slag removal surface on the first plate body and the second plate body are set to a rotating installation mode. When the bottom surface welding is completed, the lifting seat rises. During this process, the cooling surface and slag removal surface on the first plate body and the second plate body are rotated so that the slag removal surface of the first plate body faces upward and the cooling surface of the second plate body faces upward. In this way, during the rising process of the installation box, the top surface can be cooled first by the cooling surface on the second plate body, and then the slag removal surface on the first plate body can be used to remove slag from the cooled part of the top surface, thereby meeting the requirement of cooling the tooling first and then removing slag, which is beneficial to ensuring the welding quality of the tooling.

[0027] Preferably, a motor is installed on one side of the installation box, a driving gear is installed at the driving end of the motor, a driven gear is installed on the side wall of the installation box, the driving gear and the driven gear are meshed and connected, the first plate body and the second plate body are respectively installed with a first gear and a second gear, a rotating shaft is installed horizontally between the first gear, the second gear and the corresponding first plate body and the second plate body, the driven gear is rotatably connected to the rotating shaft on the first plate body, and a pulley is installed between the first gear and the second gear.

[0028] By adopting the above technical solution, specifically, when the cooling surface and the slag removal surface on the first plate body and the second plate body need to be rotated, the motor is turned on, and the motor drives the driving gear to rotate. During the rotation process, the driving gear meshes with the driven gear, driving the driven gear to rotate. During the rotation process of the driven gear, the corresponding rotating shaft is driven to rotate, and the rotating shaft drives the first gear to rotate. The first gear drives the second gear to rotate through the pulley, and then drives the corresponding rotating shaft to rotate through the second gear. The cooling surface and the slag removal surface on the first plate body and the second plate body rotate under the drive of the corresponding rotating shaft, thereby realizing the flipping of the cooling surface and the rotating surface on the first plate body and the second plate body.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the top surface welding of the tooling is completed, the tooling is flipped 180° through the flipping mechanism so that the bottom surface of the tooling faces upward, thereby facilitating the welding of the bottom surface of the tooling. At the same time, after the top surface welding is completed, it is flipped downward, and the top surface is cooled and deslaged by the first plate body and the second plate body. This allows the top surface of the tooling to be cooled and deslaged during the welding process of the bottom surface of the tooling. After the bottom surface welding is completed, the bottom surface is cooled and deslaged by the first plate body and the second plate body.

[0030] The purpose of doing this is to shorten the overall processing time of the tooling. Compared with the traditional tooling processing method, it is necessary to wait until the top and bottom surfaces are fully welded before cooling and slag removal. In the embodiment of the present application, after the top surface welding of the tooling is completed, it is not necessary to wait for the bottom surface welding to be completed before cooling and slag removal can be carried out directly, so that the top surface cooling and slag removal can be carried out simultaneously with the bottom surface welding, which can effectively avoid processing intervals during the tooling processing, and there is no need to wait until the bottom surface welding is completed before cooling, slag removal and other processes. The welding, cooling and subsequent slag removal steps in the workpiece processing process are optimized by using a flipping mechanism and a first plate body and a second plate body provided on the flipping mechanism, so that the welding, cooling and slag removal steps in the processing process can be carried out simultaneously, which is beneficial to improve the overall processing efficiency of the workpiece and facilitate the daily processing and production of the workpiece; 2. Therefore, the cooling surface and the slag removal surface on the first plate body and the second plate body are set to a rotating installation mode. When the bottom surface welding is completed, the lifting seat rises. During this process, the cooling surface and the slag removal surface on the first plate body and the second plate body are rotated so that the slag removal surface of the first plate body faces upward and the cooling surface of the second plate body faces upward. In this way, during the rising process of the installation box, the top surface can be first cooled by the cooling surface on the second plate body, and then the slag removal surface on the first plate body can be used to remove the slag from the cooled part of the top surface, thereby meeting the requirement of cooling the tooling first and then removing the slag, which is conducive to ensuring the welding quality of the tooling; 3. When the cooling surface and slag removal surface on the first plate and the second plate need to be rotated, turn on the motor, the motor drives the driving gear to rotate, the driving gear meshes with the driven gear during the rotation process, and drives the driven gear to rotate. During the rotation of the driven gear, the corresponding rotating shaft is driven to rotate, the rotating shaft drives the first gear to rotate, the first gear drives the second gear to rotate through the pulley, and then drives the corresponding rotating shaft to rotate through the second gear. The cooling surface and slag removal surface on the first plate and the second plate rotate under the drive of the corresponding rotating shaft, so as to realize the flipping of the cooling surface and rotating surface on the first plate and the second plate.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0034] Example: The present application discloses a laser welding device with a flipping mechanism. Figure 1 , including an operating table 1, the operating table 1 is in the shape of a rectangular parallelepiped as a whole, and is arranged horizontally. A sliding mechanism is arranged on one side of the operating table 1, and the sliding mechanism includes a first sliding seat 2, a second sliding seat 3 and a third sliding seat 4. The first sliding seat 2 and the second sliding seat 3 slide on the horizontal plane along the X and Y directions respectively, and the third sliding seat 4 slides in the vertical direction along the Z direction. A welding gun 5 is installed on the third sliding seat 4. A sliding rail for the first sliding seat 2 to slide is installed on the peripheral side of the operating table 1 along the X direction, and a sliding rail for the second sliding seat 3 to slide is installed on the top of the first sliding seat 2 along the Y direction. At the same time, a sliding rail for the third sliding seat 4 to slide is installed on the side wall of the second sliding seat 3 along the Z direction. In the embodiment of the present application, the first sliding seat 2, the second sliding seat 3 and the third sliding seat 4 are all driven by corresponding cylinders. A control platform is installed on one side of the operating table 1, and the specific sliding trajectories of the first sliding seat 2, the second sliding seat 3 and the third sliding seat 4 are controlled by the control platform.

[0035] The welding gun 5 is driven to slide in the three directions of X, Y and Z by the first sliding seat 2, the second sliding seat 3 and the third sliding seat 4, which is beneficial to improve the flexibility of the welding gun 5 in the welding tooling process, making the tooling more convenient and efficient in the entire welding process.

[0036] Reference Figure 1 and Figure 2 , the operating table 1 is provided with a flipping mechanism, which is used to flip the welded tooling. When the top surface welding of the tooling is completed, the tooling is flipped 180° by the flipping mechanism so that its bottom surface faces upward, and then the bottom surface of the tooling is welded by the welding gun 5. The flipping mechanism is provided with a first plate body 6 and a second plate body 7, which are both slidably arranged in the direction of approaching or moving away from the tooling, and the first plate body 6 and the second plate body 7 are provided with corresponding cooling surfaces 8 and slag removal surfaces 9, and the first plate body 6 and the second plate body 7 are used to cool and remove slag from the tooling after the tooling welding is completed. The flipping mechanism is provided with a driving mechanism, which is connected to the first plate body 6 and the second plate body 7, and the driving mechanism is used to drive the first plate body 6 and the second plate body 7 to slide in the direction of approaching or moving away from the tooling, so as to realize the cooling and slag removal of the first plate body 6 and the second plate body 7 on the side of the tooling where welding is completed.

[0037] In this arrangement, when the top surface welding of the tooling is completed, the tooling is flipped 180° by the flipping mechanism so that the bottom surface of the tooling faces upward, thereby facilitating the welding of the bottom surface of the tooling. At the same time, after the top surface welding is completed, it is flipped downward, and the top surface is cooled and deslaged by the first plate body 6 and the second plate body 7. This allows the top surface of the tooling to be cooled and deslaged during the welding process of the bottom surface of the tooling. When the bottom surface welding is completed, the bottom surface is cooled and deslaged by the first plate body 6 and the second plate body 7.

[0038] The purpose of doing so is to shorten the processing time of the tooling as a whole. Compared with the processing method of traditional tooling, it is necessary to wait until the top and bottom surfaces are fully welded before cooling and slag removal. In the embodiment of the present application, after the welding of the top surface of the tooling is completed, it is not necessary to wait for the welding of the bottom surface to be completed before cooling and slag removal can be directly carried out, so that the cooling and slag removal of the top surface can be carried out simultaneously with the welding of the bottom surface, thereby effectively avoiding the occurrence of processing intervals during the tooling processing, and there is no need to wait until the welding of the bottom surface is completed before cooling, slag removal and other processes. The welding, cooling and subsequent slag removal steps in the workpiece processing process are optimized by using a flip mechanism and a first plate body 6 and a second plate body 7 provided on the flip mechanism, so that the welding, cooling and slag removal steps can be carried out simultaneously during the processing process, thereby helping to improve the overall processing efficiency of the workpiece and facilitating the daily processing and production of the workpiece.

[0039] Specifically, refer to Figure 2 and Figure 3 The flip mechanism includes a lifting rail 10, a lifting plate 11, a lifting seat 12, a rotating shaft 13, a first rotating seat 14, a second rotating seat 15 and a moving seat 16. The lifting rail 10 is arranged vertically, and a first sliding groove 17 is provided along the length direction of the lifting rail 10. The lifting plate 11 is slidably installed in the first sliding groove 17, and the lifting plate 11 is driven by a corresponding cylinder. The lifting seat 12 is integrally connected to one side of the lifting plate 11, and the lifting plate 11 is used to drive the lifting seat 12 to slide in the vertical direction. The rotating shaft 13 is inserted into the lifting seat 12 in the horizontal direction, and the two ends of the rotating shaft 13 extend out of the two sides of the lifting seat 12 respectively. The first rotating seat 14 and the second rotating seat 15 are respectively connected to the two ends of the rotating shaft 13. When the rotating shaft 13 rotates, it synchronously drives the first rotating seat 14 and the second rotating seat 15 to rotate. At the same time, the tooling to be welded is fixedly connected to the end of the rotating shaft 13 through the corresponding fastening seat. The movable seat 16 is arranged vertically, and a horizontal slide rail 18 is installed on one side of the lifting slide rail 10 in the horizontal direction. The movable seat 16 is slidably installed on the horizontal slide rail 18. The movable seat 16 is used to drive the first rotating seat 14 to rotate. When the first rotating seat 14 rotates, the rotating shaft 13 and the second rotating seat 15 are driven to rotate synchronously. When the rotating shaft 13 rotates, it drives the tooling to flip.

[0040] For ease of understanding, in the embodiments of the present application, the top surface is taken as an example of the first welding surface for illustration.

[0041] The initial state of the tooling welding is that the lifting seat 12 is located at the bottom of the lifting slide rail 10. At this time, the tooling is connected to the rotating shaft 13 on the lifting seat 12 through the fastening seat, and two positioning seats for clamping and positioning the tooling are installed on the operating table 1. The tooling is clamped and positioned by the corresponding two positioning seats, and the welding torch 5 welds the top surface of the tooling. After the top surface welding is completed, the two positioning seats move away from each other. At this time, the lifting plate 11 rises under the drive of the cylinder and synchronously drives the lifting seat 12 to rise. As the lifting seat 12 rises, when the first rotating seat 14 rises to the top of the moving seat 16, the moving seat 16 drives the first rotating seat 14 to rotate. While the first rotating seat 14 rotates, it synchronously drives the rotating shaft 13 and the second rotating seat 15 to rotate. While the rotating shaft 13 rotates, it drives the tooling to flip.

[0042] The first rotating seat 14 rotates under the drive of the moving seat 16, thereby driving the rotating shaft 13 to rotate through the first rotating seat 14, and then driving the tooling and the second rotating seat 15 to flip through the rotating shaft 13.

[0043] One end of the second rotating seat 15 is connected to the rotating shaft 13 on the lifting seat 12, and a spring is installed at the other end of the second rotating seat 15. The other end of the spring is connected to the connecting plate at the bottom of the lifting seat 12. The spring on the second rotating seat 15 is used to assist the corresponding upper rotating member 141 and lower rotating member 142 to rotate.

[0044] Specifically, referring to Figure 2 and Figure 3 , the first rotating seat 14 includes an upper rotating member 141 and a lower rotating member 142. The upper rotating member 141 and the lower rotating member 142 are distributed one above the other. Both the upper rotating member 141 and the lower rotating member 142 are composed of a rotating plate 19 and a rotating rod 20 that are integrally connected. The two rotating plates 19 are both integrally connected to the rotating shaft 13, and the included angle between the two rotating plates 19 is 120°. The moving seat 16 is composed of a moving plate 161, a left pressing plate 162, and a right pressing plate 163. The moving plate 161 has an overall "U" - shaped structure. The left pressing plate 162 and the right pressing plate 163 are both integrally formed on the left and right sides of the top of the moving plate 161 along the horizontal direction. The left pressing plate 162 and the right pressing plate 163 are used to drive the upper rotating member 141 and the lower rotating member 142 to rotate. While the upper rotating member 141 and the lower rotating member 142 rotate, they synchronously drive the rotating shaft 13 to rotate.

[0045] For ease of understanding, in the embodiments of the present application, the example where the upper rotating member 141 is below the right pressing plate 163 and the lower rotating member 142 is below the left pressing plate 162 is used for illustration. In the actual production process, it can be determined according to the specific operation situation.

[0046] Specifically, as the lifting seat 12 rises, when the first rotating seat 14 rises to the top of the moving seat 16, in this state, the rotating rod 20 of the upper rotating member 141 is located below the right pressure plate 163. As the lifting seat 12 continues to rise, when the rotating rod 20 of the upper rotating member 141 abuts against the bottom of the right pressure plate 163, since the height of the right pressure plate 163 is fixed, after the rotating rod 20 abuts against the bottom of the pressure plate, the rotating rod 20 cannot continue to rise with the lifting seat 12. At this time, the rotating rod 20 begins to rotate with the downward pressure of the pressure plate, and drives the rotating plate 19 to start rotating, and then drives the tooling to flip through the rotating shaft 13. As the rotating shaft 13 rotates, the positions of the upper rotating member 141 and the lower rotating member 142 are exchanged during the rotation process: the upper rotating member 141 rotates to the bottom, and the lower rotating member 142 rotates to the top.

[0047] After the tooling is flipped, the lifting seat 12 descends until the tooling is clamped and positioned by the corresponding positioning seat to start welding on the bottom surface. During this process, when the upper rotating member 141 rotates to the bottom and moves down to the bottom, the upper rotating member 141 drives the moving seat 16 to slide in the horizontal direction. Here, the purpose of the sliding of the moving seat 16 is because, after the upper rotating member 141 and the lower rotating member 142 exchange positions, the position between the left pressure plate 162 of the lower rotating member 142 rotated to the top is misaligned, that is, the lower rotating member 142 at this time is not directly below the left pressure plate 162. This will result in that when the lifting seat 12 rises again and the lower rotating member 142 rises to the left pressure plate 162, the rotating rod 20 of the lower rotating member 142 is not directly below the left pressure plate 162, which also causes the left pressure plate 162 to be unable to press down the rotating rod 20 of the lower rotating member 142, and the tooling cannot be flipped.

[0048] The purpose of sliding the movable seat 16 is to move the rotating rod 20 of the lower rotating member 142 to just below the left pressure plate 162, so that when the lifting seat 12 rises again, the left pressure plate 162 can press down the rotating rod 20 on the lower rotating member 142, thereby starting the next flip.

[0049] Specifically, refer to Figure 2 and Figure 3 The middle part of the bottom of the moving plate 161 is integrally formed with a driving member 21, which is a triangular structure with wedge-shaped surfaces on the left and right sides. The driving member 21 can cooperate with the rotating rod 20 in a wedge shape, thereby driving the moving plate 161 to slide.

[0050] Specifically, when the moving plate 161 is driven to slide, the rotating rod 20 on the upper rotating member 141 rotates to the bottom and corresponds to the left wedge surface of the driving member 21. As the lifting seat 12 moves downward, when the rotating rod 20 on the upper rotating member 141 abuts against the left wedge surface of the driving member 21, the rotating rod 20 will squeeze the left wedge surface of the driving member 21 during the gradual downward movement, thereby driving the driving member 21 to slide to the right, and then driving the moving plate 161 to slide to the right through the driving member 21. While the moving plate 161 slides to the right, it can drive the left pressure plate 162 to move right to the top of the rotating rod 20 of the lower rotating member 142. When the lifting seat 12 rises again, the left pressure plate 162 can press down the rotating rod 20 of the lower rotating member 142, thereby starting the flipping of the next side.

[0051] Specifically, refer to Figure 2 and Figure 3 The driving mechanism includes a first driving block 22, a second driving block 23, an adapter plate 24, a transfer rod 25 and a mounting plate 26. The first driving block 22 is arranged vertically, and the second driving block 23 is located below the first driving block 22. The ends of the first driving block 22 and the second driving block 23 that are close to each other are both wedge-shaped, and the two wedges cooperate. The side wall of the first driving block 22 is integrally connected with the end of the lifting plate 11. The lifting plate 11 drives the first driving block 22 to be lifted and lowered synchronously while lifting and lowering. When the first driving block 22 descends, it drives the second driving block 23 to slide. The adapter plate 24 is integrally installed at the bottom of the second driving block 23, and the transfer rod 25 is integrally connected with the adapter plate 24. The transfer rod 25 is an "L"-shaped structure as a whole. One end of the transfer rod 25 is integrally connected with the bottom of the adapter plate 24, and the other end of the transfer rod 25 is welded with a mounting box 27. The first plate body 6 and the second plate body 7 are both arranged in the mounting box 27.

[0052] Specifically, when the first plate body 6 and the second plate body 7 are driven, the lifting plate 11 drives the first driving block 22 to lift and lower during the lifting process, thereby driving the second driving block 23 to slide through the first driving block 22. During the sliding process, the second driving block 23 drives the installation box 27 to slide toward or away from the tooling through the adapter plate 24 and the adapter rod 25, thereby driving the first plate body 6 and the second plate body 7 to cool and remove slag from the tooling.

[0053] Further, refer to Figure 2 and Figure 3The side wall of the mounting plate 26 is provided with an arc-shaped second chute 28, and the side wall of the second driving block 23 is welded with a slider sliding in the second chute 28. The slider drives the second driving block 23 to slide during the sliding process in the second chute 28. The purpose of doing so is that when the tooling is cooling and removing slag, the mounting box 27 needs to slide from one side of the tooling to the other side of the tooling. Since the tooling needs to be lifted and lowered when flipping, the movement trajectory of the mounting box 27 needs to be able to slide while maintaining the lifting, which requires the movement trajectory of the mounting box 27 to be an arc. The arc-shaped second chute 28 and the slider sliding in the second chute 28 are used to realize the arc-shaped movement trajectory of the second driving block 23, and the arc-shaped movement trajectory of the mounting box 27 is realized through the adapter plate 24 and the adapter rod 25.

[0054] Furthermore, multiple groups of return springs are installed in the horizontal direction on the mounting plate 26, and these return springs are connected to the second driving block 23. The return springs are used to drive the second driving block 23 to reset and help the second driving block 23 to slide. A return spring is also installed between the second driving block 23 and the adapter plate 24, and the return spring is used to assist the adapter rod 25 and the second driving block 23 to reset in the vertical direction.

[0055] Furthermore, the cooling surface 8 and the slag removal surface 9 are both rotatably mounted on the first plate body 6 and the second plate body 7, and the cooling surface 8 and the slag removal surface 9 on the first plate body 6 and the second plate body 7 are staggered. When the cooling surface 8 on the first plate body 6 faces upward, the slag removal surface 9 on the second plate body 7 faces upward; when the slag removal surface 9 on the first plate body 6 faces upward, the cooling surface 8 on the second plate body 7 faces upward. In this embodiment, a plurality of through holes are provided on the cooling surface 8, and the through holes are filled with cold air. When the tooling is cooled, the cold air in the cooling surface 8 flows out of the through holes to cool the tooling. A plurality of brushes are installed on the slag removal surface 9, and the brushes are used to remove slag from the tooling.

[0056] In this embodiment, the initial state is: the cooling surface 8 of the first plate body 6 faces upward, and the slag removal surface 9 of the second plate body 7 faces upward.

[0057] When the welding of the top surface of the tooling is completed, the lifting seat 12 rises to make the tooling flip over. The installation box 27 drives the first plate body 6 and the second plate body 7 to rise while sliding toward the other side of the tooling. When the tooling is flipped over, the welded top surface faces down and the unwelded bottom surface faces up. At this time, the cooling surface 8 of the first plate body 6 faces up and the slag removal surface 9 of the second plate body 7 faces up. After the tooling is flipped over, it starts to descend. During this process, the installation box 27 drives the first plate body 6 and the second plate body 7 to descend synchronously and drives the first plate body 6 and the second plate body 7 to slide. During the sliding process of the first plate body 6 and the second plate body 7, the first plate body 6 cools the top surface during the sliding process, and the second plate body 7 closely follows the first plate body 6. After the cooling surface 8 on the first plate body 6 cools the top surface, the slag removal surface 9 on the second plate body 7 closely following the first plate body 6 removes slag from the cooled part of the top surface.

[0058] The purpose of doing so is that it is more appropriate to remove the slag when the weld is cooled to a certain temperature. If the weld temperature is too high, the slag removal may affect the structure and properties of the weld metal, and may even cause cracks, which in turn may affect the welding quality of the tooling. In the embodiment of the present application, after the cooling surface 8 on the first plate body 6 cools the top surface, the slag removal plate on the second plate body 7 removes the slag from the portion where the top surface has been cooled, thereby effectively ensuring the welding quality of the tooling.

[0059] After the top surface welding is completed, during the process of flipping and descending, the first plate body 6 and the second plate body 7 slide from one side of the tooling to the other side of the tooling. During this sliding process, the cooling surface 8 on the first plate body 6 first cools the top surface, and then the slag removal surface 9 on the second plate body 7 removes slag from the part where the top surface cooling is completed.

[0060] Similarly, when the bottom surface welding is completed, the lifting seat 12 rises, the bottom surface is turned downward, and then the bottom surface is cooled and slag is removed through the first plate body 6 and the second plate body 7.

[0061] The purpose of setting the cooling surface 8 and the slag removal surface 9 on the first plate body 6 and the second plate body 7 in a rotating installation mode is because: when the bottom surface welding is completed, the lifting seat 12 rises, and during this rising process, the top surface is cooled and slag removed for the second time through the first plate body 6 and the second plate body 7. However, since the first cooling and slag removal of the top surface is performed with the first plate body 6 in front and the second plate body 7 in the back, when the bottom surface welding is completed, the lifting seat 12 rises, and when the installation box 27 rises at this time, the first plate body 6 is in the back and the second plate body 7 is in the front, if this is the case, then the slag removal surface 9 on the second plate body 7 is first deslagging, and then the cooling surface 8 on the first plate body 6 is cooled, which does not conform to the process of cooling the tooling first and then deslagging.

[0062] Therefore, the cooling surface 8 and the slag removal surface 9 on the first plate body 6 and the second plate body 7 are set to a rotating installation mode. When the bottom surface welding is completed, the lifting seat 12 rises. During this process, the cooling surface 8 and the slag removal surface 9 on the first plate body 6 and the second plate body 7 are rotated so that the slag removal surface 9 of the first plate body 6 faces upward and the cooling surface 8 of the second plate body 7 faces upward. In this way, during the rising process of the installation box 27, the top surface can be first cooled by the cooling surface 8 on the second plate body 7, and then the slag removal surface 9 on the first plate body 6 can be used to remove the slag from the cooled part of the top surface, thereby meeting the requirement of cooling the tooling first and then removing the slag, which is beneficial to ensuring the welding quality of the tooling.

[0063] Specifically, refer to Figure 2 and Figure 4 A motor 29 is installed on one side of the installation box 27, a driving gear 30 is installed at the driving end of the motor 29, and a driven gear 31 is installed on the side wall of the installation box 27, and the driving gear 30 and the driven gear 31 are meshed and connected. The driving gear 30 is driven by the motor 29 to rotate, and the driving gear 30 meshes with the driven gear 31 during the rotation process, driving the driven gear 31 to rotate. The first plate body 6 and the second plate body 7 are respectively installed with a first gear 32 and a second gear 33, and a rotating shaft 34 is installed between the first gear 32, the second gear 33 and the corresponding first plate body 6 and the second plate body 7 in the horizontal direction, and the driven gear 31 is rotatably connected with the rotating shaft 34 on the first plate body 6. A pulley 35 is installed between the first gear 32 and the second gear 33.

[0064] Specifically, when the cooling surface 8 and the slag removal surface 9 on the first plate body 6 and the second plate body 7 need to be rotated, the motor 29 is turned on, and the motor 29 drives the driving gear 30 to rotate. The driving gear 30 meshes with the driven gear 31 during the rotation process, driving the driven gear 31 to rotate. During the rotation of the driven gear 31, the corresponding rotating shaft 34 is driven to rotate, and the rotating shaft 34 drives the first gear 32 to rotate. The first gear 32 drives the second gear 33 to rotate through the pulley 35, and then drives the corresponding rotating shaft 34 to rotate through the second gear 33. The cooling surface 8 and the slag removal surface 9 on the first plate body 6 and the second plate body 7 rotate under the drive of the corresponding rotating shaft 34, thereby realizing the flipping of the cooling surface 8 and the rotating surface on the first plate body 6 and the second plate body 7.

[0065] The implementation principle of a laser welding device with a flipping mechanism in the embodiment of the present application is: When the top surface welding of the tooling is completed, the tooling is flipped 180° by the flipping mechanism so that the bottom surface of the tooling faces upward, thereby facilitating the welding of the bottom surface of the tooling. At the same time, after the top surface welding is completed, it is flipped downward, and the top surface is cooled and deslaged by the first plate body 6 and the second plate body 7. This allows the top surface of the tooling to be cooled and deslaged during the welding process of the bottom surface of the tooling. When the bottom surface welding is completed, the bottom surface is cooled and deslaged by the first plate body 6 and the second plate body 7.

[0066] The purpose of doing so is to shorten the processing time of the tooling as a whole. Compared with the processing method of traditional tooling, it is necessary to wait until the top and bottom surfaces are fully welded before cooling and slag removal. In the embodiment of the present application, after the welding of the top surface of the tooling is completed, it is not necessary to wait for the welding of the bottom surface to be completed before cooling and slag removal can be directly carried out, so that the cooling and slag removal of the top surface can be carried out simultaneously with the welding of the bottom surface, thereby effectively avoiding the occurrence of processing intervals during the tooling processing, and there is no need to wait until the welding of the bottom surface is completed before cooling, slag removal and other processes. The welding, cooling and subsequent slag removal steps in the workpiece processing process are optimized by using a flip mechanism and a first plate body 6 and a second plate body 7 provided on the flip mechanism, so that the welding, cooling and slag removal steps can be carried out simultaneously during the processing process, thereby helping to improve the overall processing efficiency of the workpiece and facilitating the daily processing and production of the workpiece.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
